University of La Romana > Research > Scientific Production Abierto Inglés The wafer map is a data visualization of a thin semiconductor fabric made of crystalline silicon, such as defects or test results. The wafer map is a base for creating electronic coordinate circuits and photovoltaic cells. During the wafer map production, any fault results in a product failure. The wafer map faults are undetectable to the naked eye, which is a big challenge. Hotspot detection in wafer maps is significantly important to evaluate the manufacturing process and. improve product yield. The hotspot detection in the wafer maps is the primary aim of this research. A novel wafer map hotspot detector (WHD) is proposed based on three stack fully connected conventional neural network layers and a dense layer. Data augmentation uses the segmented images of the wafers to build the proposed model. The proposed model is evaluated through several evalua-tion parameters and state-of-the-art studies comparative analysis. The proposed model achieved a 94% training and 90% testing performance accuracy for hotspot detection and shows better results than existing approaches. This study helps semiconductor engineers improve wafer manufacturing designs and efficiency in the semiconductor industry.

Subjects > Social Sciences Ibero-american International University > Research > Doctoral Thesis Cerrado Español El presente documento detalla el proceso de creación de la red neuronal artificial (RNA) para el tratamiento de efluentes mediante la determinación de la dosificación de ácido, coagulante y floculante. El proceso abarca desde el análisis de la información de las muestras de los efluentes, la creación del modelo de RNA y la predicción de dosificaciones. Este tipo de red, que se caracteriza por su organización en capas y conexiones estrictamente hacia delante, utiliza algoritmos de entrenamiento del tipo supervisado. El entrenamiento de las redes neuronales consiste en el ajuste de sus parámetros con el objetivo de generar el resultado deseado a la salida de la red. Antes de poder aplicar algún algoritmo de optimización debemos definir nuestra función de coste o pérdida. La función de pérdida es aquella expresión matemática que queremos minimizar o maximizar dependiendo del problema que estemos abordando. Una función de coste típica es la definida por la ecuación, donde se utiliza la media de la suma de los errores cuadráticos para evaluar el rendimiento de la red. Este proceso se realiza por cada ejemplo en el dataset de entrenamiento, siendo m el número de muestras. Fi = Salida de la red para el dato i. El descenso del gradiente es el método utilizado para la optimización de redes de neuronas. Esta técnica realiza actualizaciones de manera iterativa de cada parámetro de la red en aquella dirección que minimice más la función de coste. Para obtener esta dirección se calcula la derivada parcial de la función de coste con respecto a cada parámetro de manera individual. Antes de realizar el entrenamiento es necesario inicializar los parámetros de la red, siendo este un factor importante que puede determinar la convergencia o no. Fase de entrenamiento. Debido a que el objetivo final es poder determinar los niveles adecuados de dosificación para que el ph final en los efluentes cumplan con los estándares ambientales, el modelo de predicción puede adaptarse de forma que tome todas las variables, incluidas la dosificación de coagulante y floculante, y el objetivo sea la predicción del ph final. Dada un conjunto de condiciones iniciales, y un conjunto de dosificaciones el modelo será capaz de predecir el ph resultante. Este enfoque donde los niveles de dosificación de coagulante y floculante cumplen la función de variables independientes en vez de variables dependientes nos obliga a crear una matriz de valores predeterminados, donde cada una de estas configuraciones de dosificación sería evaluada por la red para obtener el valor de ph final. Mínima pre-configuración de parámetros antes de poner en marcha cada batch del proceso. Cuando se da esta señal de inicio, se activa la bomba centrífuga #3 y empieza a llenarse el tanque de ácido. Cuando eso ocurre, apaga la bomba de llenado y después de 10 segundos se activa el agitador del tanque de ácido a 15 Hz y 10 segundos después se dosifica la cantidad de peróxido seteada. Luego de 30 segundos más se dosifica el ácido según el valor seteado ya sea manualmente o mediante la red neuronal. Cuando el agua termina de caer al tanque de coagulante, luego de 10 segundos se activa el agitador del tanque de ácido a 18 Hz y 10 segundos después se dosifica la cantidad de coagulante seteada manualmente o por la red neuronal.

University of La Romana > Research > Scientific Production Abierto Inglés Histopathological evaluation is necessary for the diagnosis and grading of prostate cancer, which is still one of the most common cancers in men globally. Traditional evaluation is time-consuming, prone to inter-observer variability, and challenging to scale. The clinical usefulness of current AI systems is limited by the need for comprehensive pixel-level annotations. The objective of this research is to develop and evaluate a large-scale benchmarking study on a weakly supervised deep learning framework that minimizes the need for annotation and ensures interpretability for automated prostate cancer diagnosis and International Society of Urological Pathology (ISUP) grading using whole slide images (WSIs). This study rigorously tested six cutting-edge multiple instance learning (MIL) architectures (CLAM-MB, CLAM-SB, ILRA-MIL, AC-MIL, AMD-MIL, WiKG-MIL), three feature encoders (ResNet50, CTransPath, UNI2), and four patch extraction techniques (varying sizes and overlap) using the PANDA dataset (10,616 WSIs), yielding 72 experimental configurations. The methodology used distributed cloud computing to process over 31 million tissue patches, implementing advanced attention mechanisms to ensure clinical interpretability through Grad-CAM visualizations. The optimum configuration (UNI2 encoder with ILRA-MIL, 256 256 patches, 50% overlap) achieved 78.75% accuracy and 90.12% quadratic weighted kappa (QWK), outperforming traditional methods and approaching expert pathologist-level diagnostic capability. Overlapping smaller patches offered the best balance of spatial resolution and contextual information, while domain-specific foundation models performed noticeably better than generic encoders. This work is the first large-scale, comprehensive comparison of weekly supervised MIL methods for prostate cancer diagnosis and grading. The proposed approach has excellent clinical diagnostic performance, scalability, practical feasibility through cloud computing, and interpretability using visualization tools.

University of La Romana > Research > Scientific Production Abierto Inglés Introduction: Jackfruit cultivation is highly affected by leaf diseases that reduce yield, fruit quality, and farmer income. Early diagnosis remains challenging due to the limitations of manual inspection and the lack of automated and scalable disease detection systems. Existing deep-learning approaches often suffer from limited generalization and high computational cost, restricting real-time field deployment. Methods: This study proposes CNNAttLSTM, a hybrid deep-learning architecture integrating Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM) units, and an attention mechanism for multi-class classification of algal leaf spot, black spot, and healthy jackfruit leaves. Each image is divided into ordered 56×56 spatial patches, treated as pseudo-temporal sequences to enable the LSTM to capture contextual dependencies across different leaf regions. Spatial features are extracted via Conv2D, MaxPooling, and GlobalAveragePooling layers; temporal modeling is performed by LSTM units; and an attention mechanism assigns adaptive weights to emphasize disease-relevant regions. Experiments were conducted on a publicly available Kaggle dataset comprising 38,019 images, using predefined training, validation, and testing splits. Results: The proposed CNNAttLSTM model achieved 99% classification accuracy, outperforming the baseline CNN (86%) and CNN–LSTM (98%) models. It required only 3.7 million parameters, trained in 45 minutes on an NVIDIA Tesla T4 GPU, and achieved an inference time of 22 milliseconds per image, demonstrating high computational efficiency. The patch-based pseudo-temporal approach improved spatial–temporal feature representation, enabling the model to distinguish subtle differences between visually similar disease classes. Discussion: Results show that combining spatial feature extraction with temporal modeling and attention significantly enhances robustness and classification performance in plant disease detection. The lightweight design enables real-time and edge-device deployment, addressing a major limitation of existing deep-learning techniques. The findings highlight the potential of CNNAttLSTM for scalable, efficient, and accurate agricultural disease monitoring and broader precision agriculture applications.

University of La Romana > Research > Scientific Production Abierto Inglés Autonomous unmanned aerial vehicles (UAVs) offer cost-effective and flexible solutions for a wide range of real-world applications, particularly in hazardous and time-critical environments. Their ability to navigate autonomously, communicate rapidly, and avoid collisions makes UAVs well suited for emergency response scenarios. However, real-time path planning in dynamic and unpredictable environments remains a major challenge, especially in confined tunnel infrastructures where accidents may trigger fires, smoke propagation, debris, and rapid environmental changes. In such conditions, conventional preplanned or model-based navigation approaches often fail due to limited visibility, narrow passages, and the absence of reliable localization signals. To address these challenges, this work proposes an end-to-end emergency response framework for tunnel accidents based on Multi-Agent Reinforcement Learning (MARL). Each UAV operates as an independent learning agent using an Independent Q-Learning paradigm, enabling real-time decision-making under limited computational resources. To mitigate premature convergence and local optima during exploration, Grey Wolf Optimization (GWO) is integrated as a policy-guidance mechanism within the reinforcement learning (RL) framework. A customized reward function is designed to prioritize victim discovery, penalize unsafe behavior, and explicitly discourage redundant exploration among agents. The proposed approach is evaluated using a frontier-based exploration simulator under both single-agent and multi-agent settings with multiple goals. Extensive simulation results demonstrate that the proposed framework achieves faster goal discovery, improved map coverage, and reduced rescue time compared to state-of-the-art GWO-based exploration and random search algorithms. These results highlight the effectiveness of lightweight MARL-based coordination for autonomous UAV-assisted tunnel emergency response. ur Rehman, Hafiz Muhammad Raza and Gul, M.

University of La Romana > Research > Scientific Production Abierto Inglés New energy vehicles (NEVs) has emerged as a sustainable alternative to conventional vehicles, however have unresolved reliability challenges due to their complex electronic systems and varying operating conditions. Faults in drivetrain and battery systems, occurring at rates up to 12% annually, present significant barriers to the widespread adoption of NEVs. This study proposes a robust fault detection framework that applies multiple machine learning and deep learning models to address these challenges. The research utilizes the benchmark NEV fault diagnosis dataset, which contains real-world sensor data from NEVs. The models tested include logistic regression, passive-aggressive classifier, ridge classifier, perceptron, gated recurrent unit (GRU), convolutional neural network, and artificial neural network. The proposed ensemble GRULogX model stands out among the implemented model, leveraging GRU with logistic regression and other key classifiers, and achieved 99% accuracy, demonstrating high precision and recall. Cross-validation and hyperparameter optimization were adopted to further ensure the model’s generalizability and reliability. This research enhances the fault detection capabilities of NEVs, thereby improving their reliability and supporting the wider adoption of clean energy transportation solutions.

University of La Romana > Research > Scientific Production Abierto Inglés This research incorporates an intelligent transportation system (ITS) of smart cities with a newly developed ensemble model, termed EPYolov7x, through the association of particle swarm optimization (PSO) and YOLOv7x for high-accuracy traffic congestion prediction. In the proposed model, PSO is used for hyperparameter optimization for the YOLO model. Experimental results suggest a mean average precision (mAP) of 98.6% with an inference speed of 106 FPS on the UA-DETRAC dataset. It also provides good precision and real-time performance; both are essential for the practical deployment of ITS.

University of La Romana > Research > Scientific Production Abierto Inglés This research incorporates an intelligent transportation system (ITS) of smart cities with a newly developed ensemble model, termed EPYolov7x, through the association of particle swarm optimization (PSO) and YOLOv7x for high-accuracy traffic congestion prediction. In the proposed model, PSO is used for hyperparameter optimization for the YOLO model. Experimental results suggest a mean average precision (mAP) of 98.6% with an inference speed of 106 FPS on the UA-DETRAC dataset. It also provides good precision and real-time performance; both are essential for the practical deployment of ITS. The study findings confirm that PSO-based hyperparameter optimization improves the detection accuracy for complex traffic scenarios. The obtained results indicate superior performance compared to existing approaches. The proposed model can facilitate sustainable urban mobility toward a safer future with optimal computation.

University of La Romana > Research > Scientific Production Abierto Inglés Human activity recognition (HAR) is essential in many applications, such as smart homes, assisted living, healthcare monitoring, rehabilitation, physiotherapy, and geriatric care. Conventional methods of HAR use wearable sensors, e.g., acceleration sensors and gyroscopes. However, they are limited by issues such as sensitivity to position, user inconvenience, and potential health risks with long-term use. Optical camera systems that are vision-based provide an alternative that is not intrusive; however, they are susceptible to variations in lighting, intrusions, and privacy issues. The paper uses an optical method of recognizing human domestic activities based on pose estimation and deep learning ensemble models. The skeletal keypoint features proposed in the current methodology are extracted from video data using PoseNet to generate a privacy-preserving representation that captures key motion dynamics without being sensitive to changes in appearance. A total of 30 subjects (15 male and 15 female) were sampled across 2734 activity samples, including nine daily domestic activities. There were six deep learning architectures, namely, the Transformer (Transformer), Long Short-Term Memory (LSTM), Gated Recurrent Unit (GRU), Multilayer Perceptron (MLP), One-Dimensional Convolutional Neural Network (1D CNN), and a hybrid Convolutional Neural Network–Long Short-Term Memory (CNN–LSTM) architecture. The results on the hold-out test set show that the CNN–LSTM architecture achieves an accuracy of 98.78% within our experimental setting. Leave-One-Subject-Out cross-validation further confirms robust generalization across unseen individuals, with CNN–LSTM achieving a mean accuracy of 97.21% ± 1.84% across 30 subjects. The results demonstrate that vision-based pose estimation with deep learning is a useful, precise, and non-intrusive approach to HAR in smart healthcare and home automation systems.

University of La Romana > Research > Scientific Production Abierto Inglés Accurate short-term electricity load forecasting is essential for reliable and efficient smart city energy management, particularly in environments characterized by high-dimensional, heterogeneous, and noisy multivariate signals. However, existing forecasting models often struggle to simultaneously capture nonlinear temporal dependencies, multi-scale periodicity, and static contextual influences within a unified framework. To address this challenge, this study proposes a hybrid deep learning architecture that integrates Bidirectional Long Short-Term Memory (BiLSTM) for temporal modeling, an additive attention mechanism for adaptive time-step weighting, Fast Fourier Transform (FFT)-based frequency residual learning for periodicity extraction, and embedding-based static feature fusion for contextual representation. The model is evaluated on the ISO-NE Smart City Energy Dataset for next-hour electricity load forecasting using a two-week input window (336 hours). Experimental results demonstrate that the proposed hybrid framework significantly improves predictive accuracy, achieving an RMSE of 25.51 kW and an R of 0.9905, outperforming recurrent, convolutional, and transformer-based baselines under identical evaluation settings. Ablation analysis confirms that temporal attention and frequency-domain residual modeling contribute substantially to performance gains. These findings indicate that joint temporal–spectral modeling combined with static contextual fusion provides a robust and effective solution for complex smart-city electricity forecasting tasks.

University of La Romana > Research > Scientific Production Abierto Inglés This study presents a novel integrative approach for the analysis of high-dimensional gene expression data, leveraging the complementary strengths of unsupervised clustering and supervised classification. Using K-means clustering, the dataset is stratified into three distinct clusters, revealing intrinsic biological patterns and relationships. The resulting cluster assignments are subsequently employed as pseudo-labels to train machine learning models, including support vector machines, random forest, and a stacking ensemble classifier. To validate and enhance the robustness of clustering, complementary methodologies such as hierarchical clustering and DBSCAN are employed, with results visualized through PCA-driven dimensionality reduction. The high predictive accuracy achieved by the classifiers underscores the separability and reliability of the identified clusters. Furthermore, feature importance analysis highlighted key genetic determinants within each cluster, offering actionable insights into potential biomarkers and critical genomic features. This framework bridges the gap between exploratory unsupervised learning and predictive supervised modeling, providing a scalable and interpretable methodology for analyzing complex genomic datasets.

La transición energética hacia la neutralidad climática en 2050 plantea para la Unión Europea desafíos sin precedentes, especialmente en lo relativo a la sustitución progresiva de los combustibles fósiles por fuentes renovables sostenibles. En este contexto, la bioenergía —y en particular la biomasa forestal— constituye actualmente la principal fuente de energía renovable del continente y se proyecta como un vector estratégico para la descarbonización de sectores difíciles de electrificar, como la industria o la generación térmica. Sin embargo, su desarrollo se encuentra condicionado por un intenso debate político y científico sobre sus implicaciones ambientales, su sostenibilidad y su relación con la gestión forestal. La presente investigación analiza de forma rigurosa el papel que desempeñará la biomasa en el modelo energético europeo proyectado para 2050, comparando la demanda energética estimada en los principales escenarios de descarbonización con la disponibilidad sostenible de recursos forestales. Para ello, se realiza un estudio exhaustivo del sistema energético europeo, una revisión crítica del estado de los bosques y del potencial de biomasa, y un análisis comparativo basado en modelos integrados ampliamente utilizados por la Comisión Europea (PRIMES, GAINS, GLOBIOM).Los resultados evidencian que la bioenergía seguirá siendo necesaria para alcanzar los objetivos climáticos, siempre que su aprovechamiento se mantenga dentro de límites sostenibles y se refuercen los criterios de gestión forestal. El estudio concluye que, bajo supuestos razonables de sostenibilidad, la oferta potencial de biomasa forestal podría cubrir la demanda proyectada para 2050, sin comprometer la salud de los ecosistemas ni la función sumidero de los bosques europeos. Asimismo, se identifican riesgos, incertidumbres y diferencias regionales que deben considerarse en la planificación energética, así como recomendaciones para garantizar un uso equilibrado y sostenible de la biomasa en el marco del Pacto Verde Europeo.

La gestión sostenible del recurso hídrico un desafío critico en Honduras, en lo que respecta a
variabilidad climática y crecimiento poblacional. El estudio se realiza en la microcuenca quebrada grande,
principal fuente de abastecimiento de agua para el sector I de la ciudad de La Ceiba, en el departamento de
Atlántida, Honduras. El objetivo es crear un modelo de gestión hídrica que evalúe la demanda actual y futura
del recurso hídrico para apoyar la planificación y la toma de decisiones y garantizar el abastecimiento
sostenible de agua potable. La metodología combina un diseño no experimental descriptivo con un análisis de
datos hidrometeorológicos (precipitación y temperatura), mediciones de caudal in situ, caracterización
morfológica mediante SIG, la aplicación del método de Thornthwaite para el balance hídrico y el análisis de
la demanda poblacional actual y proyectada a 10 años. Los resultados muestran que la microcuenca tiene una
mayor capacidad de recarga hídrica (6.694. Mm3/año), aventajada por una cobertura forestal superior al 98% y
suelos con capacidad de infiltración. La oferta hídrica es más alta que la demanda actual con 1.284 Mm3 en
2024 y proyectado de 1.512 Mm3 en 2034, haciendo uso del 19 y 23% de su capacidad de retención y se
identifica una marcada estacionalidad en la disponibilidad de recurso hídrico. Para para garantizar la
sostenibilidad del recurso frente a la variabilidad climática y el futuro crecimiento demográfico, se
concluye que, aunque exista una condición de superávit hídrico, es necesario implementar un modelo de
gestión integral que incluya estrategias de conservación, gestión adaptativa y gobernanza participativa

Desde la inauguración del primer tanatorio en 1968 hasta la actualidad, en España se han construido
más de 2.500 edificaciones de este tipo, configurando una red territorial que constituye la expresión
visible del sector funerario, una industria que genera una facturación anual de 1.679 millones de euros
(Panasef, 2024). A lo largo de más de cinco décadas, esta tipología ha experimentado un desarrollo irregular
pero sostenido, alcanzando en las últimas dos décadas un notable avance cualitativo derivado tanto de la
competencia empresarial como de la creciente demanda social por espacios funerarios de mayor calidad
arquitectónica y simbólica.La investigación se dirige principalmente a arquitectos y profesionales del
ámbito funerario, aunque sus resultados proyectan un beneficio hacia la sociedad en general como usuarios
potenciales de estos espacios. El estudio propone una lectura crítica de los tanatorios construidos en
España entre 2001 y 2020, mediante su catalogación y análisis a partir de cuatro categorías de variables
(ambientales, funcionales, formales y técnicas) con el fin de identificar los factores que contribuyen a que
un tanatorio se configure como un espacio de despedida efectivo y significativo previo a la incineración o
inhumación: el penúltimo espacio. Metodológicamente, el trabajo se estructura en tres fases: (1) formulación
de una metodología para el análisis y catalogación de la muestra, (2) aplicación del modelo al conjunto de
casos seleccionados y (3) elaboración de recomendaciones orientadas tanto al diseño de nuevos tanatorios
como a la renovación de los existentes. Con ello se busca favorecer la evolución de esta tipología mediante
la experiencia acumulada, promover la integración de servicios de cremación , referenciando las buenas
prácticas de los crematorios belgas, e incorporar criterios de sostenibilidad y flexibilidad en la
arquitectura funeraria contemporánea.

En Bolivia, la actividad agroindustrial ha seguido un enfoque de planificación estrictamente sectorial, característica de economías centralizadas donde predominan jerarquías verticales. En áreas con vocación agropecuaria, los gobiernos municipales carecen de competencias para tomar decisiones en políticas agroindustriales. Desde una perspectiva socioeconómica, la agroindustria no beneficia directamente a las comunidades rurales. Esto demanda, desde el ámbito de la administración pública, integrar los procesos de gestión del desarrollo local y la gestión de desarrollo agroindustrial a nivel municipal, considerando la participación de actores locales. Esta investigación busca diseñar un modelo de gestión agroindustrial desde el gobierno municipal, basado en un enfoque de cadenas productivas, que permita contribuir a la articulación entre la gestión agroindustrial y el desarrollo local en el ámbito municipal, aprovechando recursos internos y externos, y considerando al municipio con vocación agropecuaria y agroindustrial como un sistema integrado de valor. Métodos. La investigación utilizó un enfoque combinado: cuantitativo mediante encuestas y talleres para analizar la gestión agroindustrial y su impacto en el desarrollo local; y cualitativo a través de entrevistas para entender los procesos de gestión municipal en el contexto boliviano. El diagnóstico fue exploratorio, descriptivo y explicativo, reflejando las etapas del estudio bajo una óptica sistémica. Resultados. El modelo fue validado con una metodología aplicada en el municipio de Vitichi, en el departamento de Potosí, logrando transformaciones positivas en el desarrollo local con la agroindustria como eje integrador bajo un enfoque de cadena productiva. Conclusiones. La gestión agroindustrial juega un papel crucial en el desarrollo local como pilar de la economía rural, promoviendo la transformación productiva, agregando valor, aumentando los ingresos y mejorando la seguridad alimentaria a través de un desarrollo endógeno sostenible.

This study proposes a SHAP interpretable, multi-domain supervised learning framework for predicting academic award recognition using thirty two publication count-based bibliometric indices. A balanced dataset was constructed across four disciplines, namely Computer Science, Neuroscience, Mathematics, and Civil Engineering, comprising verified awardees from recognized professional societies and matched non-awardee researchers. Eight classifiers were evaluated under stratified five fold cross validation, assessed via accuracy, precision, recall, F1-score, and ROC AUC. The framework achieved domain-specific F1-scores of 0.70 in Computer Science, 0.73 in Neuroscience, 0.72 in Civil Engineering, and 0.78 in Mathematics, with SVM and XGBoost demonstrating the strongest cross-domain robustness across disciplines. SHAP analysis consistently identified normalized h index, h2 family, q2 index, and g index as dominant cross-domain predictors, while domain-specific indicators, including Rm and w indices in Neuroscience and P index in Civil Engineering, reflected disciplinary recognition patterns. By unifying publication-based feature engineering, multi-domain classification, and SHAP explainability within a single reproducible pipeline, this framework offers a scalable, transparent, and evidence-based tool for institutional researcher evaluation.

University of La Romana > Research > Scientific Production Abierto Inglés Evaluating groundwater quality in irrigated areas is crucial for sustainable agriculture, especially as limited water resources and climate change pose significant threat to groundwater resources. Spatial information on groundwater quality is essential for effective management and utilization of water resources, particularly in intensive cropping areas such as irrigated regions in IBIS, Pakistan. However, recent advancements in machine learning (ML) techniques have highlighted that conventional groundwater quality assessment methods are costly and time-consuming, especially for developing nations. Accurate and efficient ML models can address this challenge in agricultural water management by optimally identifying the categories of water quality. This study is conducted to predict groundwater quality using an innovative ensemble-boosting methodology. The data is collected from Rahim Yar Khan’s irrigation system by the Scarp Monitoring Organization. Four irrigation water quality indicators, including sodium adsorption ratio, total dissolved solids, residual sodium carbonate, and electrical conductivity, are used to predict groundwater quality by applying four ML models. The performance of the ML models is assessed using mean squared error, correlation coefficients (r), and root mean square error measures. The proposed Gradient Boosting (GB) approach combines the advantages of interpretable tree models and boosting approaches. Experimental results validate the utility of the proposed approach with a 99% accuracy in predicting groundwater quality, compared to conventional ML techniques. Based on the proposed GB model and the inverse distance weighting interpolation technique, the groundwater quality distribution in the Hazardous Area is 17.34%, the Marginal Area is 79.36%, and the Safe Area is 3.30%. Enhancement and validation of groundwater quality index predictions are carried out using k-fold validation and hyperparameter tuning. Results indicate that the ML models have the potential to accurately delineate different groundwater quality zones for managing water resources and ensuring sustainable agriculture. Water quality assessment through the proposed approach can help managing the groundwater for the regions susceptible to deterioration of water quality thus contributing to better irrigation governance.

The performance of the ML models is assessed using mean squared error, correlation coefficients (r), and root mean square error measures. The proposed Gradient Boosting (GB) approach combines the advantages of interpretable tree models and boosting approaches. Experimental results validate the utility of the proposed approach with a 99% accuracy in predicting groundwater quality, compared to conventional ML techniques. Based on the proposed GB model and the inverse distance weighting interpolation technique, the groundwater quality distribution in the Hazardous Area is 17.34%, the Marginal Area is 79.36%, and the Safe Area is 3.30%. Enhancement and validation of groundwater quality index predictions are carried out using k-fold validation and hyperparameter tuning. Results indicate that the ML models have the potential to accurately delineate different groundwater quality zones for managing water resources and ensuring sustainable agriculture. Water quality assessment through the proposed approach can help managing the groundwater for the regions susceptible to deterioration of water quality thus contributing to better irrigation governance.

University of La Romana > Research > Scientific Production Abierto Inglés Predictive modeling for lung cancer severity often struggles with the high dimensionality and multi-domain nature of risk factors. While individual contributors like smoking are well-documented, the relative predictive weight of lifestyle, environmental, and genetic domains remains insufficiently quantified in integrated frameworks. This study proposes an explainable machine learning approach using an XGBoost classifier to evaluate these three distinct risk domains. Utilizing the UCI Machine Learning Repository Lung Cancer Dataset, we implemented a domain-wise ablation study to isolate the predictive signal of each factor group. To ensure scientific rigor and address the “black box” nature of ensemble models, we employed 5-fold stratified cross-validation and SHAP (Shapley Additive Explanations) for feature-level transparency. Our results demonstrate that the integrated model achieves a classification accuracy of 95.7% (AUC-ROC = 0.98) on this dataset. Notably, ablation analysis revealed that the Lifestyle domain retained the highest standalone predictive performance (92.9%), followed by the Genetic/Clinical domain (94.6%), while the Environmental domain showed a more pronounced performance drop (73.3%), suggesting differential information density across risk categories. SHAP analysis identified cumulative smoking exposure as the primary feature influencing model predictions within this dataset. This study presents a proof-of-concept interpretable framework for lung cancer risk stratification, demonstrating that domain-wise ablation combined with explainable AI can provide transparent, feature-level insight to support rather than replace clinical judgment in settings where comprehensive diagnostic testing may be limited.

University of La Romana > Research > Scientific Production Abierto Inglés Identifying the emotional state of individuals has useful applications, particularly to reduce the risk of suicide. Users’ thoughts on social media platforms can be used to find cues on the emotional state of individuals. Clinical approaches to suicide ideation detection primarily rely on evaluation by psychologists, medical experts, etc., which is time-consuming and requires medical expertise. Machine learning approaches have shown potential in automating suicide detection. In this regard, this study presents a soft voting ensemble model (SVEM) by leveraging random forest, logistic regression, and stochastic gradient descent classifiers using soft voting. In addition, for the robust training of SVEM, a hybrid feature engineering approach is proposed that combines term frequency-inverse document frequency and the bag of words. For experimental evaluation, “Suicide Watch” and “Depression” subreddits on the Reddit platform are used. Results indicate that the proposed SVEM model achieves an accuracy of 94%, better than existing approaches. The model also shows robust performance concerning precision, recall, and F1, each with a 0.93 score. ERT and deep learning models are also used, and performance comparison with these models indicates better performance of the SVEM model. Gated recurrent unit, long short-term memory, and recurrent neural network have an accuracy of 92% while the convolutional neural network obtains an accuracy of 91%. SVEM’s computational complexity is also low compared to deep learning models. Further, this study highlights the importance of explainability in healthcare applications such as suicidal ideation detection, where the use of LIME provides valuable insights into the contribution of different features. In addition, k-fold cross-validation further validates the performance of the proposed approach.

University of La Romana > Research > Scientific Production Abierto Inglés The Polyphagous Shot Hole Borer (PSHB) is a highly invasive beetle that has been spreading like an epidemic across agricultural and forestry landscapes in recent years. Its rapid and destructive spread has turned it into a major global threat, causing widespread damage that continues to grow with time. Countries like South Africa, the United States, and Australia have implemented extensive measures to control the spread of PSHB, including the establishment of specialized agricultural support centers for early detection. However, there is still a strong need to make PSHB detection more accessible, allowing even non-experts to easily identify infections at an early stage. Artificial Intelligence (AI) has shown great promise in plant disease detection, but a major challenge in the case of PSHB was the lack of a suitable dataset for training AI models. In the proposed work, we first created a dedicated dataset by collecting images of trees infected with PSHB. We applied a range of preprocessing techniques to refine the dataset and prepare it for AI applications. Building on this, we developed a novel AI-based method, where we trained a deep learning model using a multi-convolutional layer network combined with a Fourier transformation layer. Additionally, an attention mechanism and advanced feature extraction techniques were incorporated to further boost model performance. As a result, the proposed approach achieved an impressive top accuracy of 92.3% in detecting PSHB infections, showing the potential of AI to offer a simple, efficient, and highly accurate solution for early disease detection.

University of La Romana > Research > Scientific Production Abierto Inglés Vulnerability of potato crops to diseases and pest infestation can affect its quality and lead to significant yield losses. Timely detection of such diseases can help take effective decisions. For this purpose, a deep learning-based object detection framework is designed in this study to identify and classify major potato diseases and pests under real-world field conditions. A total of 2,688 field images were collected from two research farms in Punjab, Pakistan, across multiple growth stages in various seasonal conditions. Excluding 285 symptoms-free images from the earliest collection led to 2,403 images which were annotated into four biotic-stress classes: blight disease (n = 630), leaf spot disease (n = 370), leafroll virus (viral symptom complex; n = 888), and Colorado potato beetle (larvae/adults; n = 515), indicating class imbalance. Several state-of-the-art models were used including YOLOv8 variants (n/s/m), YOLOv7, YOLOv5, and Faster R-CNN, and the results are discussed in relation to recent potato disease classification studies involving cropped leaf images. Stratified splitting (70% training, 20% validation, 10% testing) was applied to preserve class distribution across all subsets. YOLOv8-medium achieve the best performance with mean average precision (mAP)@0.5 of 98% on the held-out test images. Results for stable 5-fold cross-validation show a mean mAP@0.5 of 97.8%, which offers a balance between accuracy and inference time. Model robustness was evaluated using 5-fold cross-validation and repeated training with different random seeds, showing a low variance of ±0.4% mAP. Results demonstrate promising outcomes under the real-world field conditions, while, broader cross-region and cross-season validation is intended for the future.

Ibero-american International University > Research > Articles and Books Abierto Inglés Secure and scalable authentication remains a fundamental challenge in Internet of Things (IoT) networks due to constrained device resources, dynamic topology, and the absence of centralized trust infrastructures. Conventional password-based and certificate-driven authentication schemes incur high computation, storage, and communication overhead, limiting their suitability for large-scale deployments. To address these limitations, this paper proposes ScLBS, a federated learning (FL)–based self-certified authentication scheme for distributed and sustainable IoT environments. ScLBS integrates self-certified public key cryptography with FL-driven trust adaptation, enabling decentralized public key derivation without reliance on third-party certificate authorities or exposure of private credentials. A zero-knowledge mechanism combined with location-aware authentication strengthens resistance to impersonation, Sybil, and replay attacks. Hierarchical key management supported by a -tree enables efficient group rekeying and preserves forward and backward secrecy under dynamic membership. Formal security verification is conducted under the Dolev–Yao adversary model using ProVerif, confirming secrecy of private and session keys (SKs) and correctness of authentication. Extensive NS-3 simulations and ablation analysis demonstrate that ScLBS achieves lower authentication delay, reduced message overhead, improved network utilization, and decreased energy consumption compared to representative IoT authentication schemes, while maintaining bounded FL overhead. These results indicate that ScLBS provides a balanced trade-off between security strength, scalability, and resource efficiency for constrained IoT networks. Chithaluru, Premkumar and Jyothi, B.

University of La Romana > Research > Scientific Production Abierto Inglés The digital era, while offering unparalleled access to information, has also seen the rapid proliferation of fake news, a phenomenon with the potential to distort public perception and influence sociopolitical events. The need to identify and mitigate the spread of such disinformation is crucial for maintaining the integrity of public discourse. This research introduces a multi-view learning framework that achieves high precision by systematically integrating diverse feature perspectives. Using a diverse dataset of news articles, the approach combines several feature extraction methods, including TF-IDF for individual words (unigrams) and word pairs (bigrams), and counts vectorization to represent text in multiple ways. To capture additional linguistic and semantic information, advanced features, such as readability scores, sentiment scores, and topic distributions generated by latent Dirichlet allocation (LDA), are also extracted. The framework implements a multi-view learning strategy, where separate views focus on basic text, linguistic, and semantic features, feeding into a final ensemble model. Models like logistic regression, random forest, and LightGBM are employed to analyze each view, and a stacked ensemble integrates their outputs. Through rigorous tenfold cross-validation, our proposed multi-view ensemble achieves a state-of-the-art accuracy of 0.9994, outperforming strong baselines, including single-view models and a BERT-based classifier.

University of La Romana > Research > Scientific Production Abierto Inglés Botnets are used for malicious activities such as cyber-attacks, spamming, and data theft and have become a significant threat to cyber security. Despite existing approaches for cyber attack detection, botnets prove to be a particularly difficult problem that calls for more advanced detection methods. In this research, a stacking classifier is proposed based on K-nearest neighbor, support vector machine, decision tree, random forest, and multilayer perceptron, called KSDRM, for botnet detection. Logistic regression acts as the meta-learner to combine the predictions from the base classifiers into the final prediction with the aim of increasing the overall accuracy and predictive performance of the ensemble. The UNSW-NB15 dataset is used to train machine learning models and evaluate their effectiveness in detecting cyber-attacks on IoT networks. The categorical features are transformed into numerical values using label encoding. Machine learning techniques are adopted to recognize botnet attacks to enhance cyber security measures. The KSDRM model successfully captures the complex patterns and traits of botnet attacks and obtains 99.99% training accuracy. The KSDRM model also performs well during testing by achieving an accuracy of 97.94%. Based on 3, 5, 7, and 10 folds, the k-fold cross-validation results show that the proposed method’s average accuracy is 99.89%, 99.88%, 99.89%, and 99.87%, respectively. Further, the demonstration of experiments and results shows the KSDRM model is an effective method to identify botnet-based cyber attacks. The findings of this study have the potential to improve cyber security controls and strengthen networks against changing threats.

University of La Romana > Research > Scientific Production Abierto Inglés In the rapidly advanced and evolving information technology industry, adequate client engagement plays a critical role as it is very important to understand the client’s concerns, and requirements, have the records, authorizations, and go-ahead of previously agreed requirements, and provide the feasible solution accordingly. Previously multiple solutions have been proposed to enhance the efficiency of client engagement, but they lack traceability, trust, transparency, and conflict in agreements of previous contracts. Due to the lack of these shortcomings, the client requirement is getting delayed which is causing client escalations, integrity issues, project failure, and penalties. In this study, we proposed the UniferCollab framework to overcome the issues of collaboration between various teams, transparency, the record of client authorizations, and the go-ahead on previous developments by implementing blockchain technology. We store the data on the permissible network in the proposed approach. It allows us to compile all the requirements and information shared by clients on permissible blockchain to secure a large amount of data which enhances the traceability of all the requirements. All the authorizations from the client generate push notifications for any changes in their current system executed through smart contracts. It removes the ambiguity between various development teams if the client has only shared the requirement with one team. The data is stored in the decentralized network from where information is gathered which resolves the traceability, transparency, and trust issues. Lastly, evaluations involved a total of 800 hypertext transfer protocol (HTTP) requests tested using Postman with blockchain block sizes ranging from 0.568 KB to 550 KB and an average size increase of 280 KB was observed as new blocks were added. The longest chain in the network was observed during 800 repetitions of blockchain operations. Latency analysis revealed that delays in processing HTTP requests were influenced by decentralized node processing, local machine response times, and internet bandwidth through various experiments. Results show that the proposed framework resolves all client engagement issues in implementation between all stakeholders which enhances trust, and transparency improves client experience and helps us manage disputes effectively.

El propósito de este estudio es efectuar un análisis meticuloso que aproveche el excedente del sargazo buscando minimizar los efectos al medio ambiente, confeccionando un conglomerado en proporciones recomendables cuya mezcla de hormigón con sargazo posiblemente se pueda utilizar en el sector de la construcción. El sargazo es un alga pelágica que forma parte de la flora oceánica de las regiones tropicales siendo fundamental para el equilibrio de los ecosistemas marinos, sin embargo, su frecuencia y aumento constante en los últimos años en las costas del Mar Caribe y Golfo de México, ha producido un desequilibrio natural, cambios sustanciales por una mezcla de olores fétidos y alta toxicidad ocasionado por la liberación excesiva de ácido sulfhídrico que lo contiene, ya que tan solo en 2018 se identificaron alrededor de 160 000 toneladas, desde el norte desde la Isla Contoy hasta Tulum al sur, generando considerables afectaciones al turismo y a los habitantes que viven de los servicios que éstos prestan. La necesidad de obtener materiales alternativos al concreto convencional se han incrementado; en esa búsqueda, el concreto reforzado con fibras ha presentado características de una solución con viabilidad técnica y económica, así, se han utilizado diferentes tipos de fibras: acero, vidrio, carbón, fibras minerales y naturales (madera, yute, bambú, coco, henequén, asbesto, lana, entre otros), fibras de polipropileno y muchas otras fibras sintéticas como el nylon. Bajo muestras controladas minuciosamente y probadas en laboratorio, se buscará obtener una mezcla de concreto con sargazo con resistencia apropiada para su uso, además, otra prueba detallada será que, si al ir aumentando la cantidad el sargazo como componente principal de la mezcla tan solo con agua, dé como resultado una mayor resistencia o no, apegándonos a las normas internacionales, vigentes.

En vista del aumento en el consumo de energía eléctrica y la limitación de recursos energéticos, es evidente que se deben buscar soluciones para optimizar el consumo, promover la integración de fuentes renovables y reducir el impacto ambiental. Los Sistemas de Gestión de Energía para el Hogar (HEMS) se presentan como una alternativa razonable que ayudan a optimizar el consumo, a reducir las emisiones de gases de efecto invernadero y contribuyen a combatir el calentamiento global. Por otro lado, la inteligencia artificial (IA) se ha venido utilizando en diversos campos y, en el contexto de la reducción del consumo de energía, ha propiciado una transformación significativa en los HEMS, desempeñando un gran papel en la mejora tanto de la eficiencia como de la sostenibilidad energética.En este trabajo se desarrolla un modelo de predicción de consumo de energía que integraalgoritmos de inteligencia artificial en un sistema de administración de energía en el hogar(HEMS), maximizando la eficiencia energética y reduciendo los efectos negativos sobre el medio ambiente. En particular vamos a integrar un algoritmo de Aprendizaje Profundo (DL),aprovechando sus ventajas para mejorar la toma de decisiones en HEMS. El diseño del sistema se basa en un banco de pruebas que contiene cinco dispositivos típicos del hogar, cada uno conectado a un medidor inteligente. Los datos de consumo energético se ingresan al módulo de IA, donde el algoritmo de predicción genera predicciones del consumo que ayudaran a los usuarios a tomar decisiones sobre el consumo energético y optimizar su consumo futuro.

A thorough examination of hate speech detection methods in a variety of settings, such as code-mixed, multilingual, visual, audio, and textual scenarios, is presented in this paper. Unlike previous research focusing on single modalities, our study thoroughly examines hate speech identification across multiple forms. We classify the numerous types of hate speech, showing how it appears on different platforms and emphasizing the unique difficulties in multi-modal and multilingual settings. We fill research gaps by assessing a variety of methods, including deep learning, machine learning, and natural language processing, especially for complicated data like code-mixed and cross-lingual text. Additionally, we offer key technique comparisons, suggesting future research avenues that prioritize multi-modal analysis and ethical data handling, while acknowledging its benefits and drawbacks. This study attempts to promote scholarly research and real-world applications on social media platforms by acting as an essential resource for improving hate speech identification across various data sources.

La industria 4.0 se ha ido instalando en todos los sectores productivos en la actualidad y la agroindustria azucarera no es la excepción, sin embargo, aún existen brechas que acortar. En esta investigación se presenta un modelo de evaluación de madurez de industria 4.0 para el sector azucarero, así como su aplicación en un estudio de casos en el Ingenio Azucarero Melchor Ocampo y la asociación de agricultores del valle El Grullo Autlan. Si bien existen varios modelos de evaluación no hay uno enfocado para este tipo de industria. Para la construcción del modelo se hizo una exhaustiva revisión bibliográfica tomándose como base modelos de industria 4.0 y de tecnología habilitadora tanto de uso general cómo de la agroindustria y en particular de la azucarera, así mismo se consideraron indicadores de la agenda para el desarrollo sostenible de la ONU y de indicadores de la Global Reporting Initiative. El modelo consta de cuatro dimensiones; capacidad tecnológica, capacidad organizativa, capacidad estratégica y capacidad sustentable, en los cuáles se integran 10 criterios, 30 indicadores y 67 preguntas consecuentemente. Para la aplicación se formó un grupo experimental que se le aplicó el modelo desarrollado y uno grupo de control al cual solo se le aplicó una posprueba para validar la hipótesis de estudio: “El uso del modelo de evaluación de Industria 4.0 de la agroindustria azucarera por las partes interesadas favorece a una identificación de sus capacidades tecnológicas, organizativas, estratégicas y sostenibles en la Industria 4.0, en comparación de las que no lo utilizan.” Los resultados confirmaron esta hipótesis, ya que el grupo que utilizó el MEAI previamente mostró mayor identificación de dichas capacidades en la prueba final, evidenciándose con las medidas de tendencia central y la prueba U de Mann-Whitney.

La gestión de proyectos ha sido un campo en constante evolución, buscando siempre mejorar sus procesos y resultados. Uno de los aspectos clave en esta mejora continua es la capacidad de aprender de experiencias pasadas (lecciones aprendidas), el cual bien aplicado, ayuda a la buena toma de decisiones y por ende a lograr el éxito en la gestión de proyectos. Sin embargo, a pesar de la importancia reconocida de las lecciones aprendidas y de las ventajas potenciales, su gestión eficaz sigue siendo un desafío para muchas organizaciones. Para resolver este problema, se identifica la necesidad de desarrollar una metodología que permita una gestión simple, flexible y efectiva de las lecciones aprendidas. Una de las herramientas tecnológicas que ayudaría a mejorar el uso de estas lecciones aprendidas, es la inteligencia artificial (IA), debido a su ventaja de aprendizaje y mejoría con el tiempo, además de su adaptación rápida a las necesidades requeridas. En este trabajo doctoral se desarrolla el diseño de un algoritmo de inteligencia artificial (IA), que consiste en el diseño y entrenamiento de una red neuronal artificial (RNA), para optimizar la generación y aplicación de la gestión de lecciones aprendidas a lo largo del ciclo de vida de un proyecto, permitiendo su identificación, clasificación y aplicación efectiva, de manera que la red neuronal identifique patrones y tendencias que contribuyan a mejorar la toma de decisiones y la ejecución de futuros proyectos. Los resultados de esta investigación presentan la identificación de casos de usos que establece un hilo conductor en la implementación y el desarrollo de dos RNA, una para la predicción de resultados de una actividad de un proyecto y otra para recomendar valores de recursos (costo, tiempo u otro). La valides mostrada en los resultadas es que en la primera RNA su exactitud está cerca al 100%, en ambas la perdida es cercana a 0%, por lo que se concluye que las RNA diseñadas se han entrenado con excelentes resultados.

University of La Romana > Research > Scientific Production Abierto Inglés Forest fires pose significant threats to ecosystems, human life, and the global climate, necessitating rapid and reliable detection systems. Traditional fire detection approaches, including sensor networks, satellite monitoring, and centralized image analysis, often suffer from delayed response, high false positives, and limited deployment in remote areas. Recent deep learning-based methods offer high classification accuracy but are typically computationally intensive and unsuitable for low-power, real-time edge devices. This study presents an autonomous, edge-based forest fire and smoke detection system using a lightweight MobileNetV2 convolutional neural network. The model is trained on a balanced dataset of fire, smoke, and non-fire images and optimized for deployment on resource-constrained edge devices. The system performs near real-time inference, achieving a test accuracy of 97.98% with an average end-to-end prediction latency of 0.77 s per frame (approximately 1.3 FPS) on the Raspberry Pi 5 edge device. Predictions include the class label, confidence score, and timestamp, all generated locally without reliance on cloud connectivity, thereby enhancing security and robustness against potential cyber threats. Experimental results demonstrate that the proposed solution maintains high predictive performance comparable to state-of-the-art methods while providing efficient, offline operation suitable for real-world environmental monitoring and early wildfire mitigation. This approach enables cost-effective, scalable deployment in remote forest regions, combining accuracy, speed, and autonomous edge processing for timely fire and smoke detection.

The model is trained on a balanced dataset of fire, smoke, and non-fire images and optimized for deployment on resource-constrained edge devices. The system performs near real-time inference, achieving a test accuracy of 97.98% with an average end-to-end prediction latency of 0.77 s per frame (approximately 1.3 FPS) on the Raspberry Pi 5 edge device. Predictions include the class label, confidence score, and timestamp, all generated locally without reliance on cloud connectivity, thereby enhancing security and robustness against potential cyber threats. Experimental results demonstrate that the proposed solution maintains high predictive performance comparable to state-of-the-art methods while providing efficient, offline operation suitable for real-world environmental monitoring and early wildfire mitigation. This approach enables cost-effective, scalable deployment in remote forest regions, combining accuracy, speed, and autonomous edge processing for timely fire and smoke detection.

The proposed approach integrates DenseNet with ResNet-50, VGG-19, and GoogLeNet using an innovative bonding process that establishes algorithmic channeling between these models. The goal targets compact efficient image feature vectors that process data in parallel regardless of input color or grayscale consistency and work across different datasets and semantic categories. Image patching techniques with corner straddling and isolated responses help detect peaks and junctions while addressing anisotropic noise through curvature-based computations and auto-correlation calculations. An integrated channeled algorithm processes the refined features by uniting local-global features with primitive-parameterized features and regioned feature vectors. Using K-nearest neighbor indexing methods analyze and retrieve images from the harmonized signature collection effectively. Extensive experimentation is performed on the state-of-the-art datasets including Caltech-101, Cifar-10, Caltech-256, Cifar-100, Corel-10000, 17-Flowers, COIL-100, FTVL Tropical Fruits, Corel-1000, and Zubud.

University of La Romana > Research > Scientific Production Abierto Inglés Epileptic seizures are neurological events characterized by sudden and excessive electrical discharges in the brain, leading to disruptions in brain function. Epileptic seizures can lead to life-threatening situations such as status epilepticus, which is characterized by prolonged or recurrent seizures and may lead to respiratory distress, aspiration pneumonia, and cardiac arrhythmias. Therefore, there is a need for an automated approach that can efficiently diagnose epileptic seizures at an early stage. The primary objective of this study is to develop a highly accurate approach for the early diagnosis of epileptic seizures. We use electroencephalography (EEG) signal data based on different brain activities to conduct experiments for epileptic seizure detection. For this purpose, a novel transfer learning technique called random forest-gated recurrent unit (RFGR) is proposed. The EEG brain activity signal data is fed into the RFGR model to generate a new feature set. The newly generated features are based on the class prediction probabilities extracted by the RFGR and are utilized to train models. Extensive experiments are carried out to investigate the performance of the proposed approach. Results demonstrate that the RFGR, when used with the random forest model, outperforms state-of-the-art techniques, achieving a high accuracy of 99.00 %. Additionally, explainable artificial intelligence analysis is utilized to provide transparent and understandable explanations of the decision-making processes of the proposed approach.

University of La Romana > Research > Scientific Production Abierto Inglés The emergence of social media platforms led to the sharing of ideas, thoughts, events, and reviews. The shared views and comments contain people’s sentiments and analysis of these sentiments has emerged as one of the most popular fields of study. Sentiment analysis in the Urdu language is an important research problem similar to other languages, however, it is not investigated very well. On social media platforms like X (Twitter), billions of native Urdu speakers use the Urdu script which makes sentiment analysis in the Urdu language important. In this regard, an ensemble model RRLS is proposed that stacks random forest, recurrent neural network, logistic regression (LR), and support vector machine (SVM). The Internet Movie Database (IMDB) movie reviews and Urdu tweets are examined in this study using Urdu sentiment analysis. The Urdu hack library was used to preprocess the Urdu data, which includes preprocessing operations including normalizing individual letters, merging them, including spaces, etc. concerning punctuation. The problem of accurately encoding Urdu characters and replacing Arabic letters with their Urdu equivalents is fixed by the normalization module. Several models are adopted in this study for extensive evaluation of their accuracy for Urdu sentiment analysis. While the results promising, among machine learning models, the SVM and LR attained an accuracy of 87%, according to performance criteria such as F-measure, accuracy, recall, and precision. The accuracy of the long short-term memory (LSTM) and bidirectional LSTM (BiLSTM) was 84%. The suggested ensemble RRLS model performs better than other learning algorithms and achieves a 90% accuracy rate, outperforming current methods. The use of the synthetic minority oversampling technique (SMOTE) is observed to improve the performance and lead to 92.77% accuracy.

Este trabajo tiene como objetivo evaluar el desempeño de los Planes Municipales de Desarrollo (PMD) que contribuya a la planificación prospectiva del Municipio de Florencia - Caquetá desde la perspectiva de los Objetivos de Desarrollo Sostenible (ODS); en un horizonte de 20 años. Asimismo, aborda el análisis de la medición del desempeño de la administración municipal durante los últimos 16 años, cuyos resultados muestran un bajo posicionamiento en el ranking nacional por municipios según la medición anual realizada por el Departamento Nacional de Planeación (DNP, 2018), en el cual ocupó el puesto 197 en 2008 y el puesto 667 en 2009, con indicadores de pobreza (41,3%) muy superiores al promedio nacional (27,8%). La metodología que se utilizó se sustenta en un alcance descriptivo longitudinal con un enfoque mixto, que abordó desde el modelo prospectivo, partiendo de un diagnóstico situacional hasta la construcción de escenarios y acciones estratégicas. Se uso el método de análisis de correspondencia y descriptivo para caracterizar el objeto de estudio definido por dimensiones y variables. La recolección de información se hizo a partir de un cuestionario estructurado y talleres a un grupo de expertos (política pública, gremiales y comunitarios) sobre el objeto de estudio con el fin de determinar las variables claves, con las cuales se simularon los escenarios prospectivos desde el software MICMAC, MACTOR y SMIC. Los resultados permiten reconocer los beneficios de implementar métodos prospectivos en la medición de desempeño de entidades territoriales y sus resultados a futuro. Finalmente, se concluye cuáles son las principales decisiones por tomar en el presente del municipio, y su impacto en la construcción de escenarios fiscales y de responsabilidad en la gestión integral.

El río Rímac, es la principal fuente de agua de la cuenca hidrológica de la ciudad de Lima. Sin embargo, es el más deteriorado por la actividad humana. Las alteraciones en el uso de la tierra afectan significativamente el flujo base del río, lo que provoca una menor disponibilidad de agua para la agricultura y los residentes de la región. La cuenca del río Rímac ha sido degradada por las actividades antropogénicas, lo que limita su capacidad de servicios ecosistémicos como la regulación hídrica. Poco más del 42% corresponde a suelo desnudo y 48% del área de la cuenca está cubierta por vegetación natural compuesta por bosques, arbustos, pajonal y humedales. El presente estudio tiene como objetivo simular el efecto del cambio de uso del suelo producido por un portafolio de proyectos de infraestructura natural sobre el caudal base del río Rímac. El periodo de simulación de datos es del 2011 al 2016.La presente investigación se ha dividido en dos etapas, en la primera se contempla la generación de un portafolio de proyectos de infraestructura natural mediante el uso del modelo RIOS, en la segunda, se pretende determinar la eficiencia hídrica del portafolio de proyectos mediante el uso del modelo SWAT. Se identificaron tres portafolios de proyectos de infraestructura natural de 1) 2,800 hectáreas, 2) 6,500 hectáreas y 3) 10,700 hectáreas respectivamente. Basados principalmente en la recuperación de tres tipos de ecosistemas (infraestructura natural): bosques degradados, arbustos degradados y pajonal altoandino degradado. Es posible afirmar que, de acuerdo con los resultados obtenidos, a mayor infraestructura natural, mayor caudal base. Los Portafolios 1, 2 y 3 tienen un efecto positivo sobre el caudal base, produciendo mayor caudal que el escenario de línea base respectivamente. Este estudio presenta varias limitaciones que no han sido analizadas. Una de ellas tiene que ver con la evaluación de los efectos del cambio climático sobre el caudal base del río Rímac, así como la recuperación de los usos de suelo, como por ejemplo recuperar suelos desnudos y suelos agrícolas.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Accurate solar and photovoltaic (PV) power forecasting is essential for optimizing grid integration, managing energy storage, and maximizing the efficiency of solar power systems. Deep learning (DL) models have shown promise in this area due to their ability to learn complex, non-linear relationships within large datasets. This study presents a systematic literature review (SLR) of deep learning applications for solar PV forecasting, addressing a gap in the existing literature, which often focuses on traditional ML or broader renewable energy applications. This review specifically aims to identify the DL architectures employed, preprocessing and feature engineering techniques used, the input features leveraged, evaluation metrics applied, and the persistent challenges in this field. Through a rigorous analysis of 26 selected papers from an initial set of 155 articles retrieved from the Web of Science database, we found that Long Short-Term Memory (LSTM) networks were the most frequently used algorithm (appearing in 32.69% of the papers), closely followed by Convolutional Neural Networks (CNNs) at 28.85%. Furthermore, Wavelet Transform (WT) was found to be the most prominent data decomposition technique, while Pearson Correlation was the most used for feature selection. We also found that ambient temperature, pressure, and humidity are the most common input features. Our systematic evaluation provides critical insights into state-of-the-art DL-based solar forecasting and identifies key areas for upcoming research. Future research should prioritize the development of more robust and interpretable models, as well as explore the integration of multi-source data to further enhance forecasting accuracy. Such advancements are crucial for the effective integration of solar energy into future power grids.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Accurate solar and photovoltaic (PV) power forecasting is essential for optimizing grid integration, managing energy storage, and maximizing the efficiency of solar power systems. Deep learning (DL) models have shown promise in this area due to their ability to learn complex, non-linear relationships within large datasets. This study presents a systematic literature review (SLR) of deep learning applications for solar PV forecasting, addressing a gap in the existing literature, which often focuses on traditional ML or broader renewable energy applications. This review specifically aims to identify the DL architectures employed, preprocessing and feature engineering techniques used, the input features leveraged, evaluation metrics applied, and the persistent challenges in this field. Through a rigorous analysis of 26 selected papers from an initial set of 155 articles retrieved from the Web of Science database, we found that Long Short-Term Memory (LSTM) networks were the most frequently used algorithm (appearing in 32.69% of the papers), closely followed by Convolutional Neural Networks (CNNs) at 28.85%. Furthermore, Wavelet Transform (WT) was found to be the most prominent data decomposition technique, while Pearson Correlation was the most used for feature selection. We also found that ambient temperature, pressure, and humidity are the most common input features. Our systematic evaluation provides critical insights into state-of-the-art DL-based solar forecasting and identifies key areas for upcoming research. Future research should prioritize the development of more robust and interpretable models, as well as explore the integration of multi-source data to further enhance forecasting accuracy. Such advancements are crucial for the effective integration of solar energy into future power grids.

La présente thèse a pour objectif de proposer aux habitants de la localité de PK 18 au Cameroun des formulations pour la construction de leur logement en brique de terre comprimée.
La caractérisation du sol a révélé que celui-ci est un sable argileux. Diverses formulations ont été effectuées pour des proportions de 15 % de sciure de bois constituée du mélange de deux essences de bois (Sapelli ; Iroko) dans les proportions (100 % ; 0 %), (25 % ; 75 %), (50 % ; 50 %), (75 % ; 25 %) et (0 % ; 100 %) et stabilisées avec 8 % de ciment ou de chaux éteinte. Les briques de terre ont été produites sous une pression de compactage statique de 3,6 MPa.
Nous avons observé que l’ajout de 15 % de sciure de bois améliore globalement les propriétés physiques et thermiques, mais diminue les propriétés mécaniques des BTC. Nous avons également observé que les propriétés mécaniques, physiques et thermiques n’évoluent pas systématiquement dans le même sens que la proportion d’essence présente dans le mélange de sciure et ayant les meilleures propriétés correspondantes. D’autre part, l’ajout de 8 % de ciment ou de chaux améliore globalement les propriétés physiques et mécaniques et augmente les propriétés thermiques des BTC.
Enfin, à l’exception de l’échantillon terre + Sapelli + chaux, treize formulations des BTC stabilisées aux liants ont été proposées aux habitants de la localité de PK 18 pour la construction des logements. Cependant, pour les BTC non stabilisées au liant, seules les formulations terre + 15 % Iroko et terre + 15 % sciure (25 % Sapelli + 75 % Iroko) sont convenables. Un modèle de portique a enfin été proposé pour estimer la résistance à la compression des BTC via l’essai de flexion 3 points.

University of La Romana > Research > Scientific Production Abierto Inglés Background Deep learning models assist ophthalmologists in early detection of diseases from retinal images and timely treatment. Aim Owing to robust and accurate results from deep learning models, we aim to use convolutional neural network (CNN) to provide a non-invasive method for early detection of eye diseases. Methodology We used a hybridized CNN with deep learning (DL) based on two separate CNN blocks, to identify multiple Optic Disc Cupping, Diabetic Retinopathy, Media Haze, and Healthy images. We used the RFMiD dataset, which contains various categories of fundus images representing different eye diseases. Data augmenting, resizing, coping, and one-hot encoding are used among other preprocessing techniques to improve the performance of the proposed model. Color fundus images have been analyzed by CNNs to extract relevant features. Two CCN models that extract deep features are trained in parallel. To obtain more noticeable features, the gathered features are further fused utilizing the Canonical Correlation Analysis fusion approach. To assess the effectiveness, we employed eight classification algorithms: Gradient boosting, support vector machines, voting ensemble, medium KNN, Naive Bayes, COARSE- KNN, random forest, and fine KNN. Results With the greatest accuracy of 93.39%, the ensemble learning performed better than the other algorithms. Conclusion The accuracy rates suggest that the deep learning model has learned to distinguish between different eye disease categories and healthy images effectively. It contributes to the field of eye disease detection through the analysis of color fundus images by providing a reliable and efficient diagnostic system.

University of La Romana > Research > Scientific Production Abierto Inglés In the rapidly evolving landscape of artificial intelligence (AI) and the Internet of Things (IoT), the significance of device diagnostics and prognostics is paramount for guaranteeing the dependable operation and upkeep of intricate systems. The capacity to precisely diagnose and preemptively predict potential failures holds the potential to considerably amplify maintenance efficiency, diminish downtime, and optimize resource allocation. The wealth of information offered by telemetry data gathered from IoT devices presents an opportunity for diagnostics and prognostics applications. However, extracting valuable insights and making well-timed decisions from this extensive data reservoir remains a formidable challenge. This study proposes a novel AI-driven framework that integrates forward chaining and backward chaining algorithms to analyze telemetry data from IoT devices. The proposed methodology utilizes rule-based inference to detect real-time anomalies and predict potential future failures, providing a dual-layered approach for diagnostics and prognostics. The results show that the diagnostics engine using forward chaining detects real-time issues like “High Temperature” and “Low Pressure,” while the prognostics engine with backward chaining predicts potential future occurrences of these issues, enabling proactive prevention measures. The experimental results demonstrate that adopting this approach could offer valuable assistance to authorities and stakeholders.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Faced with anomalies in medical images, Deep learning is facing major challenges in detecting, diagnosing, and classifying the various pathologies that can be treated via medical imaging. The main challenges encountered are mainly due to the imbalance and variability of the data, as well as its complexity. The detection and classification of skin diseases is one such challenge that researchers are trying to overcome, as these anomalies present great variability in terms of appearance, texture, color, and localization, which sometimes makes them difficult to identify accurately and quickly, particularly by doctors, or by the various Deep Learning techniques on offer. In this study, an innovative and robust hybrid architecture is unveiled, underscoring the symbiotic potential of wavelet decomposition in conjunction with EfficientNet models. This approach integrates wavelet transformations with an EfficientNet backbone and incorporates advanced data augmentation, loss function, and optimization strategies. The model tested on the publicly accessible HAM10000 and ISIC2017 datasets has achieved an accuracy rate of 94.7%, and 92.2% respectively.

University of La Romana > Research > Scientific Production Abierto Inglés Background/Objectives: Estimating energy and macronutrients from food images is clinically relevant yet challenging, and rigorous evaluation requires transparent accuracy metrics with uncertainty and clear acknowledgement of reference data limitations across heterogeneous sources. This study assessed ChatGPT-5, a general-purpose vision-language model, across four scenarios differing in the amount and type of contextual information provided, using a composite dataset to quantify accuracy for calories and macronutrients. Methods: A total of 195 dishes were evaluated, sourced from Allrecipes.com, the SNAPMe dataset, and Home-prepared, weighed meals. Each dish was evaluated under Case 1 (image only), Case 2 (image plus standardized non-visual descriptors), Case 3 (image plus ingredient lists with amounts), and Case 4 (replicates Case 3 but excluding the image). The primary endpoint was kcal Mean Absolute Error (MAE); secondary endpoints included Median Absolute Error (MedAE) and Root Mean Square Error (RMSE) for kcal and macronutrients (protein, carbohydrates, and lipids), all reported with 95% Confidence Intervals (CIs) via dish-level bootstrap resampling and accompanied by absolute differences (Δ) between scenarios. Inference settings were standardized to support reproducibility and variance estimation. Source stratified analyses and quartile summaries were conducted to examine heterogeneity by curation level and nutrient ranges, with additional robustness checks for error complexity relationships. Results and Discussion: Accuracy improved from Case 1 to Case 2 and further in Case 3 for energy and all macronutrients when summarized by MAE, MedAE, and RMSE with 95% CIs, with absolute reductions (Δ) indicating material gains as contextual information increased. In contrast to Case 3, estimation accuracy declined in Case 4, underscoring the contribution of visual cues. Gains were largest in the Home-prepared dietitian-weighed subset and smaller yet consistent for Allrecipes.com and SNAPMe, reflecting differences in reference curation and measurement fidelity across sources. Scenario-level trends were concordant across sources, and stratified and quartile analyses showed coherent patterns of decreasing absolute errors with the provision of structured non-visual information and detailed ingredient data. Conclusions: ChatGPT-5 can deliver practically useful calorie and macronutrient estimates from food images, particularly when augmented with standardized nonvisual descriptors and detailed ingredients, as evidenced by reductions in MAE, MedAE, and RMSE with 95% CIs across scenarios. The decline in accuracy observed when the image was omitted, despite providing detailed ingredient information, indicates that visual cues contribute meaningfully to estimation performance and that improvements are not solely attributable to arithmetic from ingredient lists. Finally, to promote generalizability, it is recommended that future studies include repeated evaluations across diverse datasets, ensure public availability of prompts and outputs, and incorporate systematic comparisons with non-artificial-intelligence baselines.

University of La Romana > Research > Scientific Production Abierto Inglés The agriculture field is the basis of a country’s change and financial system. Crops are the main source of revenue for the people. One of the farmer’s most challenging problems is choosing the right crops for their land. This critical decision has a direct impact on productivity and profit. Wrong crop selection not only reduces yields but also causes food shortages, creating more problems for farmers. The best crop depends on many parameters such as illustration humidity, N, K, P, pH, rainfall, and temperature of the soil. Getting advice from experts is not an easy task. This requires intelligent models in crop recommendations that use machine-learning models to suggest suitable crops for soil and other environmental conditions. Temperature, humidity, and pH are important data for growing crops in agriculture. In this study, we gather and preprocess relevant data. To recommend the most suitable crop, we propose a novel ensemble learning approach called RFXG based on random forest (RF) and extreme gradient boosting (XGB) to suggest the best crop out of the twenty-two major crops. To measure the capability of the proposed approach, various machine learning models are utilized including extra tree classifier, multilayer perceptron, RF, decision trees, logistic regression, and XGB classifiers. To get the best performance, optimization of hyperparameter, and K-fold cross-validation procedures are performed. Experimental outcomes show that the proposed RFXG technique achieves a recommendation accuracy is 98%. Specifically, the proposed solution provides immediate recommendations to help farmers make timely decisions.

Subjects > Social Sciences Ibero-american International University > Research > Doctoral Thesis Cerrado Español La presente tesis de doctorado aborda el problema de la toma de decisiones empresariales, haciendo énfasis en qué tanto se tiene en cuenta o no los efectos medioambientales de los proyectos que una empresa como Ecopetrol lleva a cabo en Colombia, teniendo en cuenta que la industria de los combustibles fósiles es una de las que más contribuye en la producción de gases efecto invernadero, lo que a su vez ocasiona efectos negativos en el fenómeno del cambio climático. En este orden de ideas, se analizó la situación actual de la empresa, tanto en cuanto a su contribución con la economía nacional, como en su compromiso con el cuidado de los ecosistemas donde opera. Se observa que la empresa si toma medidas para disminuir los efectos de sus operaciones en el medio ambiente, pero estas no son suficientes. De otro lado, se analiza, si la empresa, y la industria petrolera en general, tiene en cuenta o no el factor de la Huella Ecológica (HE) en su modelo de toma de decisiones y cuáles serían los beneficios socioeconómicos de hacerlo. Se concluye que la empresa, aun conociendo los beneficios de este indicador no lo considera formalmente dentro de sus principios de Responsabilidad Social Empresarial, pero sus ejecutivos coinciden en afirmar que sí es necesario y pertinente adoptar un modelo más enfocado en la sostenibilidad ambiental, tomando como referencia el factor de la HE. Teniendo esto en cuenta, tras el análisis de la situación actual, se ofrece un modelo alternativo de toma de decisiones con un enfoque claramente socio-ambiental.

Subjects > Social Sciences Ibero-american International University > Research > Doctoral Thesis Cerrado Español La presente tesis de doctorado aborda el problema de la toma de decisiones empresariales, haciendo énfasis en qué tanto se tiene en cuenta o no los efectos medioambientales de los proyectos que una empresa como Ecopetrol lleva a cabo en Colombia, teniendo en cuenta que la industria de los combustibles fósiles es una de las que más contribuye en la producción de gases efecto invernadero, lo que a su vez ocasiona efectos negativos en el fenómeno del cambio climático. En este orden de ideas, se analizó la situación actual de la empresa, tanto en cuanto a su contribución con la economía nacional, como en su compromiso con el cuidado de los ecosistemas donde opera. Se observa que la empresa si toma medidas para disminuir los efectos de sus operaciones en el medio ambiente, pero estas no son suficientes. De otro lado, se analiza, si la empresa, y la industria petrolera en general, tiene en cuenta o no el factor de la Huella Ecológica (HE) en su modelo de toma de decisiones y cuáles serían los beneficios socioeconómicos de hacerlo. Se concluye que la empresa, aun conociendo los beneficios de este indicador no lo considera formalmente dentro de sus principios de Responsabilidad Social Empresarial, pero sus ejecutivos coinciden en afirmar que sí es necesario y pertinente adoptar un modelo más enfocado en la sostenibilidad ambiental, tomando como referencia el factor de la HE. Teniendo esto en cuenta, tras el análisis de la situación actual, se ofrece un modelo alternativo de toma de decisiones con un enfoque claramente socio-ambiental. Dicho modelo fue sometido, usando el método Delphi, a la revisión de trece expertos y de dicho ejercicio metodológico se llega a una propuesta final que es la contribución más importante de la presente tesis doctoral a la industria petrolera colombiana.

La salud de la población juega un papel determinante en el desarrollo económico y social del país y debido a la emergencia sanitaria desatada por el COVID 19, la necesidad de atención médica en Guatemala se ha agravado. En ese sentido, las instituciones encargadas de la prestación de servicios de salud pública tienen destinado presupuesto para construir infraestructura hospitalaria. Dentro de ese esquema se identifica que los procesos de finalización e inauguración de nuevos centros hospitalarios sobrepasa el tiempo planificado impactando negativamente en la salud de la población y esto se debe a cambios en el diseño y aumento del presupuesto durante el desarrollo de dichos proyectos. Sobre la base de lo expuesto y a través de un diagnóstico de necesidades, utilizando un instrumento dicotómico cerrado y entrevistas, se propone implementar un manual de recomendaciones para diseños de infraestructura de hospitales públicos mediante Building Information Modeling (BIM) en Guatemala. Metodológicamente, se adoptó el enfoque de Proyecto Especial apoyado en una investigación descriptiva, y de campo. Siendo importante destacar la inclusión de estrategias de implementación y difusión a través de normas y requisitos obligatorios, características y recomendaciones de la metodología para instituciones encargadas del desarrollo de infraestructura para hospitales. Finalmente, la implementación BIM tendrá un impacto positivo en la atención de la salud de la población en general, aporte social sobre políticas de transparencia, incremento del potencial económico a través del ahorro de costos y supervisión, mejora del índice de atención medica en infraestructura estandarizada y modernización de diseños de infraestructura hospitalaria. Aunado a la situación, se pueden seguir realizando estudios de investigación científica a la infraestructura de hospitales a través de las dimensiones BIM y la actualización de planes, programas y manuales derivados del presente trabajo.

University of La Romana > Research > Scientific Production Abierto Inglés This study emphasizes a multi-pronged approach to improving the energy efficiency of Multi-Effect Evaporator (MEE) in the paper industry. By incorporating traditional Energy-Saving Schemes (ESSs) and innovative renewable energy sources, the study demonstrates significant potential for reducing energy consumption and environmental impact, making it a decisive pathway for industrial sustainability. Key ESS strategies include Thermo-Vapor Compressors, Feed Preheaters, and Steam- and Feed-Split, which are employed to enhance Steam Economy (SE) to evaluate MEE efficiency. This integration results in a 67.93% enhancement in SE, reducing energy consumption significantly. Further, SE enhancement is achieved by integrating flash tanks that capture and reuse excess heat, which boosts SE by an additional 5.89%, leading to a total improvement of 73% without additional energy consumption. A significant innovation in the study is the integration of Linear Fresnel Reflectors (LFRs) based solar collectors and turbine-based wind energy sources to power the MEE and reduce reliance on conventional energy. This hybrid system decreases energy dependence by 62% for the base MEE and 34% for the hybrid MEE. The results are validated by comparing them with existing studies, confirming the effectiveness of the proposed method and offering significant energy and environment savings.

University of La Romana > Research > Scientific Production Abierto Inglés Maize is a staple crop worldwide, essential for food security, livestock feed, and industrial uses. Its health directly impacts agricultural productivity and economic stability. Effective detection of maize crop health is crucial for preventing disease spread and ensuring high yields. This study presents VG-GNBNet, an innovative transfer learning model that accurately detects healthy and infected maize crops through a two-step feature extraction process. The proposed model begins by leveraging the visual geometry group (VGG-16) network to extract initial pixel-based spatial features from the crop images. These features are then further refined using the Gaussian Naive Bayes (GNB) model and feature decomposition-based matrix factorization mechanism, which generates more informative features for classification purposes. This study incorporates machine learning models to ensure a comprehensive evaluation. By comparing VG-GNBNet's performance against these models, we validate its robustness and accuracy. Integrating deep learning and machine learning techniques allows VG-GNBNet to capitalize on the strengths of both approaches, leading to superior performance. Extensive experiments demonstrate that the proposed VG-GNBNet+GNB model significantly outperforms other models, achieving an impressive accuracy score of 99.85%. This high accuracy highlights the model's potential for practical application in the agricultural sector, where the precise detection of crop health is crucial for effective disease management and yield optimization.

University of La Romana > Research > Scientific Production Abierto Inglés Wheat is one of the world’s most widely cultivated cereal crops and is a primary food source for a significant portion of the population. Wheat goes through several distinct developmental phases, and accurately identifying these stages is essential for precision farming. Determining wheat growth stages accurately is crucial for increasing the efficiency of agricultural yield in wheat farming. Preliminary research identified obstacles in distinguishing between these stages, negatively impacting crop yields. To address this, this study introduces an innovative approach, MobDenNet, based on data collection and real-time wheat crop stage recognition. The data collection utilized a diverse image dataset covering seven growth phases ‘Crown Root’, ‘Tillering’, ‘Mid Vegetative’, ‘Booting’, ‘Heading’, ‘Anthesis’, and ‘Milking’, comprising 4496 images. The collected image dataset underwent rigorous preprocessing and advanced data augmentation to refine and minimize biases. This study employed deep and transfer learning models, including MobileNetV2, DenseNet-121, NASNet-Large, InceptionV3, and a convolutional neural network (CNN) for performance comparison. Experimental evaluations demonstrated that the transfer model MobileNetV2 achieved 95% accuracy, DenseNet-121 achieved 94% accuracy, NASNet-Large achieved 76% accuracy, InceptionV3 achieved 74% accuracy, and the CNN achieved 68% accuracy. The proposed novel hybrid approach, MobDenNet, that synergistically merges the architectures of MobileNetV2 and DenseNet-121 neural networks, yields highly accurate results with precision, recall, and an F1 score of 99%. We validated the robustness of the proposed approach using the k-fold cross-validation. The proposed research ensures the detection of growth stages with great promise for boosting agricultural productivity and management practices, empowering farmers to optimize resource distribution and make informed decisions.

These shapes are fundamental in mathematics education and geometric problem-solving, serving as intuitive visual aids for understanding complex concepts and theories. Recognizing hand-drawn shapes accurately enables more efficient digitization of handwritten notes, enhances educational tools, and improves user interaction with mathematical software. This research proposes an innovative machine learning algorithm for the automatic classification of mathematical geometric shapes to identify and interpret these shapes from handwritten input, facilitating seamless integration with digital systems. We utilized a benchmark dataset of mathematical shapes based on a total of 20,000 images with eight classes circle, kite, parallelogram, square, rectangle, rhombus, trapezoid, and triangle. We introduced a novel machine-learning algorithm CnN-RFc that uses convolution neural networks (CNN) for spatial feature extraction and the random forest classifier for probabilistic feature extraction from image data. Experimental results illustrate that using the CnN-RFc method, the Light Gradient Boosting Machine (LGBM) algorithm surpasses state-of-the-art approaches with high accuracy scores of 98% for hand-drawn shape classification.

University of La Romana > Research > Scientific Production Abierto Inglés A bone fracture is a medical condition characterized by a partial or complete break in the continuity of the bone. Fractures are primarily caused by injuries and accidents, affecting millions of people worldwide. The healing process for a fracture can take anywhere from one month to one year, leading to significant economic and psychological challenges for patients. The detection of bone fractures is crucial, and radiographic images are often relied on for accurate assessment. An efficient neural network method is essential for the early detection and timely treatment of fractures. In this study, we propose a novel transfer learning-based approach called MobLG-Net for feature engineering purposes. Initially, the spatial features are extracted from bone X-ray images using a transfer model, MobileNet, and then input into a tree-based light gradient boosting machine (LGBM) model for the generation of class probability features. Several machine learning (ML) techniques are applied to the subsets of newly generated transfer features to compare the results. K-nearest neighbor (KNN), LGBM, logistic regression (LR), and random forest (RF) are implemented using the novel features with optimized hyperparameters. The LGBM and LR models trained on proposed MobLG-Net (MobileNet-LGBM) based features outperformed others, achieving an accuracy of 99% in predicting bone fractures. A cross-validation mechanism is used to evaluate the performance of each model. The proposed study can improve the detection of bone fractures using X-ray images.

Un problema al DHCP es la conectividad, en donde los dispositivos conectados pueden ocasionar saturación del rango de direcciones IP. Un 60% de los dispositivos conectados a una red inalámbrica ocupan una IP durante todo el tiempo de arrendamiento sin ser utilizada, debido a su movilidad entre las redes disponibles, por lo que una configuración unificada en el tiempo de arrendamiento y el rango de direcciones IP en cada segmento de red resulta en un uso ineficiente de las IP. En este trabajo, tras analizar el comportamiento de conectividad y el rendimiento del DHCP en la red inalámbrica del campus de la Zona Poniente de la Universidad Autónoma de San Luis Potosí, se plantea el desarrollo de un modelo de optimización dinámica del DHCP para la asignación de direcciones IP mediante un algoritmo implementado en software libre como una solución al problema de saturación en las subredes del campus. Los resultados muestran que este algoritmo desarrollado permitió mejorar la conectividad en las redes inalámbricas en un 98% al ajustar sus tiempos de arrendamiento y en un 100% al gestionar adecuadamente la distribución del rango de direcciones IP en cada segmento de red. Este algoritmo funciona como un agente intermedio que se encarga de inspeccionar el comportamiento y rendimiento de DHCP y buscar de manera autónoma la solución inmediata a la saturación de direcciones IP en la subred.

A gestão de projetos tem passado por gradativa evolução através da consolidação de várias práticas disponíveis no mundo, sejam elas acessíveis virtualmente ou difundidas de forma aplicada e exemplificada no lançamento de novos produtos. No entanto, consolidar a gestão de projetos com a execução das atividades, contemplando todas as dimensões necessárias, torna-se algo desafiador para a grande maioria dos gestores. Neste trabalho, buscou-se otimizar as etapas de processos na gestão de projetos de uma empresa multinacional localizada em Manaus, Brasil, com o intuito de que todas as fases fossem executadas e o projeto finalizado. Um dos pontos principais desta pesquisa esteve relacionado ao modo de como realizar o aproveitamento do conhecimento e habilidades dos participantes da equipe de gestão de projeto. Dependendo da escolha, pode tornar o desempenho do gerenciamento do projeto mais produtivo e com resultados previsíveis. O estudo foi fundamentado a partir de duas premissas básicas: a primeira teve foco na escolha da equipe de projetos e a segunda na definição de um método científico utilizado que impossibilitasse aos envolvidos realizarem tarefas que não estivessem em conformidade com a execução detalhada no projeto. Para realizar a gestão dos projetos, foi necessário que o líder de projeto definisse sua equipe de acordo com as interações necessárias das atividades, estabelecendo critérios que minimizassem erros e obtivessem resultados promissores desde a implantação à conclusão do projeto. Como resultado, foi possível adotar as ferramentas abordadas e praticadas durante todo o processo da implantação de um projeto, através da aplicação de um questionário que facilitou o entendimento das dúvidas da equipe, fazendo com o que a liderança pudesse direcionar mais eficazmente as atividades, alcançando os objetivos planejados e validado através da equipe de projeto, que foi fundamental para sua conclusão e êxito.

En Colombia, aún coexisten diversos problemas ambientales muy a pesar de la vinculación de Colombia a la Organización para la Cooperación y el Desarrollo Económico – OCDE en el año 2018, lo que implicaría mejoras ambientales. Por ello, el presente estudio se orienta a criticar la realidad medio-ambiental en Bucaramanga y Barrancabermeja (Santander, COLOMBIA) considerando los compromisos ambientales del país ante la Organización para la Cooperación y el Desarrollo Económico (OCDE) desde el análisis de los planes y proyectos desarrollados durante el proceso de admisión y final adhesión de Colombia a la OCDE, casos: Bucaramanga y Barrancabermeja. La investigación es de nivel descriptivo en donde es clave el análisis tanto del conocimiento como de la percepción de los diferentes actores involucrados en el tema para lo cual se utilizó como técnicas la entrevista y la encuesta que contó como instrumento un cuestionario policotomizado, el cual se aplicó de manera presencial, tomando cuatro dimensiones específicas en materia medio ambiental: (a) minería, (b) recursos hídricos (c) manejo de residuos sólidos y (d) aire. Finalmente, se logró identificar la realidad medio-ambiental durante y después del proceso de admisión de Colombia a la OCDE; teniendo como resultados una realidad medio ambiental que sigue en desventaja ya que el país ha dejado de cumplir mayormente con los compromisos por una falta de organización y planeación por parte del gobierno colombiano a pesar de todas las condiciones establecidas por el organismo internacional dadas por la incorporación. Se espera que, con este acceso a la OCDE, Colombia como nación pueda ser más comprometida y estar mejor asesorada por los países integrantes, con el fin de avanzar de colectivamente hacia el desarrollo sostenible del país.

La seguridad y confiabilidad de los activos en el sector de Petróleo y Gas se considera fundamental para maximizar la disponibilidad y minimizar el tiempo de inactividad en la producción y las operaciones. La industria, debido al envejecimiento de los activos (elementos mecánicos), está revisando la planificación del mantenimiento de los equipos críticos a través del Mantenimiento centrado en la confiabilidad (RCM). Este proyecto de investigación se centra en Tibú que es la zona de la explotación petrolera mas grande del nor-oriente colombiano, en producción a la fecha de 113 pozos activos, con 41 unidades hidráulicas de velocidad variable 2 (VSH-2) y el resto corresponde a otro tipo de equipos. La extracción de crudo mediante equipos mecánicos como las VSH-2, es factor primordial en el sector petrolero cuando los yacimientos pierden presión y no fluyen naturalmente y es necesario ayudar al yacimiento para estimular la extracción del crudo del pozo. El principal problema objeto de estudio es establecer el rediseño del elemento mecánico VSH-2 mediante la identificación de la frecuencia de falla y los costos generados mediante el mantenimiento correctivo y preventivo. Como parte de la metodología, se utilizo el método de Análisis de Modo y Efecto de Fallas (AMEF), los datos recopilados en los historiales de mantenimiento en base a datos utilizando el software SAP, considerando a su vez la experiencia del grupo de mantenimiento del campo Tibú. Los principales resultados mostraron que el rediseño del elemento mecánico VSH-2 se aumento significativamente la confiabilidad del sistema de extracción mecánica de crudo cambiando el sistema de maguera por tubería de acero inoxidable 316. Basado en datos de confiabilidad, los resultados mostraron que con el rediseño se se aumento la fiabilidad del sistema en un 90% con 92,000 h de trabajo en la frecuencia de fallas presentadas por el sistema en relación con la Manguera Manifold a Acumulador Nitrógeno por el modo de falla fuga externa medio auxiliar que era de 11,900 h. Finalmente, con este rediseño se tuvieron en cuenta normas y teorías de mantenimiento (planes y rutas) lo que permitió aumentar tanto la confiablidad del sistema de extracción mecánica de petróleo como los recursos financieros del campo de extracción de petróleo relacionado con paradas debido a mantenimiento.

Uno de los principales desafíos para optimizar el acceso a internet es evitar la saturación de la red, ya que la alta demanda puede llevar a lentitud e ineficiencias. Aproximadamente el 60% de las solicitudes de usuarios en una red resultan en accesos repetidos al mismo contenido, lo cual consume ancho de banda significativo y puede sobrecargar los puntos de acceso a internet. Para abordar este problema, la implementación de una granja de servidores caché en modo transparente ofrece una solución eficiente. Esta configuración permite almacenar temporalmente el contenido de acceso frecuente en servidores locales, reduciendo así la necesidad de recuperar repetidamente datos de fuentes externas. En este trabajo, tras analizar el comportamiento de acceso a internet y el rendimiento de los recursos de red en la Universidad Autónoma de San Luis Potosí, se propone un modelo de optimización mediante una granja de servidores caché en modo transparente basada en software libre. Esta solución disminuye la demanda de ancho de banda interceptando y almacenando en caché los datos solicitados con frecuencia. Los resultados muestran una mejora del 98% en el tiempo de respuesta para solicitudes de contenido repetido y una notable disminución en la saturación del acceso a internet.

Existing automatic inspection approaches lack high robustness, as well as portability, and have movement restrictions and complexity. This study presents the design and development of a scalable, comprehensive automated inspection, cleaning, and evaluation mechanism (CAICEM) for large-sized pipelines and barrels with diameters in the range of 105 mm–210 mm. The proposed system is divided into electrical and mechanical assemblies that are independently designed, tested, fabricated, integrated, and controlled with industrial grid controllers and processors. These actuators are suitably programmed to provide the desired actions through toggle switches on a simple housing subassembly. The stress analysis and material specifications are obtained using ANSYS to ensure robustness and practicability. Later, on-ground testing and optimization are performed before industrial prototyping. The inspection system of the proposed mechanism includes barrel-mounted and brush-mounted cameras with sensors utilized to keep track of the pipeline deposits and monitor user activity. The experimental results demonstrate that the proposed mechanism is cost-effective and achieves the desired objectives with minimum human efforts in the least possible time for both smooth and rifled large-diameter pipes and barrels.

La presente investigación aborda el estudio de las asistencias tecnológicas, abreviadas como AT, para evidenciar la falta de información, sistematización y pérdida de estos recursos en Chile. Su objetivo es crear una herramienta para sistematizar el análisis de costo y responder a la mala gestión de asistencia tecnológica personalizada a través de la figura del experto en AT en Chile, con el fin de resguardar los recursos nacionales y satisfacer las necesidades personales de los usuarios. La falta de recursos materiales y culturales se evidenciará a partir de una revisión sistemática establecida por la Sociedad de Tecnología e Ingeniería de Rehabilitación de Norte América; mientras que la sistematización del análisis de costo y gestión, junto con la validación de la figura de experto en AT, se realizará a través de un enfoque mixto, cuantitativo y cualitativo de encuestas y entrevistas a expertos en el área que se desempeñan en el diseño, fabricación, modificación y distribución de esta tecnología personalizada en América Latina. Se espera evidenciar que la falta de conocimiento crea pérdidas en los recursos en el Estado al entregar productos estandarizados que no responden a sus necesidades individuales y geográficas. Al sistematizar los procesos de análisis de costo y gestión de AT, se pueden identificar los elementos y las metodologías necesarias para la adecuación y distribución efectiva de estas tecnologías para trabajar en conjunto con el usuario y articular soluciones personalizadas a sus necesidades cotidianas.

University of La Romana > Research > Scientific Production Abierto Inglés Gender classification plays a vital role in various applications, particularly in security and healthcare. While several biometric methods such as facial recognition, voice analysis, activity monitoring, and gait recognition are commonly used, their accuracy and reliability often suffer due to challenges like body part occlusion, high computational costs, and recognition errors. This study investigates gender classification using gait data captured by Ultra-Wideband radar, offering a non-intrusive and occlusion-resilient alternative to traditional biometric methods. A dataset comprising 163 participants was collected, and the radar signals underwent preprocessing, including clutter suppression and peak detection, to isolate meaningful gait cycles. Spectral features extracted from these cycles were transformed using a novel integration of Feedforward Artificial Neural Networks and Random Forests , enhancing discriminative power. Among the models evaluated, the Random Forest classifier demonstrated superior performance, achieving 94.68% accuracy and a cross-validation score of 0.93. The study highlights the effectiveness of Ultra-wideband radar and the proposed transformation framework in advancing robust gender classification.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Objectives: Mechanical ventilator plays a vital role in saving millions of lives. Patients with COVID-19 symptoms need a ventilator to survive during the pandemic. Studies have reported that the mortality rates rise from 50% to 97% in those requiring mechanical ventilation during COVID-19. The pumping of air into the patient’s lungs using a ventilator requires a particular air pressure. High or low ventilator pressure can result in a patient’s life loss as high air pressure in the ventilator causes the patient lung damage while lower pressure provides insufficient oxygen. Consequently, precise prediction of ventilator pressure is a task of great significance in this regard. The primary aim of this study is to predict the airway pressure in the ventilator respiratory circuit during the breath. Methods: A novel hybrid ventilator pressure predictor (H-VPP) approach is proposed. The ventilator exploratory data analysis reveals that the high values of lung attributes R and C during initial time step values are the prominent causes of high ventilator pressure. Results: Experiments using the proposed approach indicate H-VPP achieves a 0.78 R2, mean absolute error of 0.028, and mean squared error of 0.003. These results are better than other machine learning and deep learning models employed in this study. Conclusion: Extensive experimentation indicates the superior performance of the proposed approach for ventilator pressure prediction with high accuracy. Furthermore, performance comparison with state-of-the-art studies corroborates the superior performance of the proposed approach.

Patients with COVID-19 symptoms need a ventilator to survive during the pandemic. Studies have reported that the mortality rates rise from 50% to 97% in those requiring mechanical ventilation during COVID-19. The pumping of air into the patient’s lungs using a ventilator requires a particular air pressure. High or low ventilator pressure can result in a patient’s life loss as high air pressure in the ventilator causes the patient lung damage while lower pressure provides insufficient oxygen. Consequently, precise prediction of ventilator pressure is a task of great significance in this regard. The primary aim of this study is to predict the airway pressure in the ventilator respiratory circuit during the breath.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Extracting knowledge from hybrid data, comprising both categorical and numerical data, poses significant challenges due to the inherent difficulty in preserving information and practical meanings during the conversion process. To address this challenge, hybrid data processing methods, combining complementary rough sets, have emerged as a promising approach for handling uncertainty. However, selecting an appropriate model and effectively utilizing it in data mining requires a thorough qualitative and quantitative comparison of existing hybrid data processing models. This research aims to contribute to the analysis of hybrid data processing models based on neighborhood rough sets by investigating the inherent relationships among these models. We propose a generic neighborhood rough set-based hybrid model specifically designed for processing hybrid data, thereby enhancing the efficacy of the data mining process without resorting to discretization and avoiding information loss or practical meaning degradation in datasets. The proposed scheme dynamically adapts the threshold value for the neighborhood approximation space according to the characteristics of the given datasets, ensuring optimal performance without sacrificing accuracy. To evaluate the effectiveness of the proposed scheme, we develop a testbed tailored for Parkinson’s patients, a domain where hybrid data processing is particularly relevant. The experimental results demonstrate that the proposed scheme consistently outperforms existing schemes in adaptively handling both numerical and categorical data, achieving an impressive accuracy of 95% on the Parkinson’s dataset. Overall, this research contributes to advancing hybrid data processing techniques by providing a robust and adaptive solution that addresses the challenges associated with handling hybrid data, particularly in the context of Parkinson’s disease analysis.

University of La Romana > Research > Scientific Production Abierto Inglés The provision of Wireless Fidelity (Wi-Fi) service in an indoor environment is a crucial task and the decay in signal strength issues arises especially in indoor environments. The Line-of-Sight (LOS) is a path for signal propagation that commonly impedes innumerable indoor objects damage signals and also causes signal fading. In addition, the Signal decay (signal penetration), signal reflection, and long transmission distance between transceivers are the key concerns. The signals lose their power due to the existence of obstacles (path of signals) and hence destroy received signal strength (RSS) between different communicating nodes and ultimately cause loss of the packet. Thus, to solve this issue, herein we propose an advanced model to maximize the LOS in communicating nodes using a modern indoor environment. Our proposal comprised various components for instance signal enhancers, repeaters, reflectors,. these components are connected. The signal attenuation and calculation model comprises of power algorithm and hence it can quickly and efficiently find the walls and corridors as obstacles in an indoor environment. We compared our proposed model with state of the art model using Received Signal Strength (RSS) and Packet Delivery Ratio (PDR) (different scenario) and found that our proposed model is efficient.

University of La Romana > Research > Scientific Production Cerrado Inglés The correct analysis of medical images requires the medical knowledge and expertise of radiologists to understand, clarify, and explain complex patterns and diagnose diseases. After analyzing, radiologists write detailed and well-structured reports that contribute to the precise and timely diagnosis of patients. However, manually writing reports is often expensive and time-consuming, and it is difficult for radiologists to analyze medical images, particularly images with multiple views and perceptions. It is challenging to accurately diagnose diseases, and many methods are proposed to help radiologists, both traditional and deep learning-based. Automatic report generation is widely used to tackle this issue as it streamlines the process and lessens the burden of manual labeling of images. This paper introduces a systematic literature review with a focus on analyses and evaluating existing research on medical report generation. This SLR follows a proper protocol for the planning, reviewing, and reporting of the results. This review recognizes that the most commonly used deep learning models are encoder-decoder frameworks (45 articles), which provide an accuracy of around 92–95%. Transformers-based models (20 articles) are the second most established method and achieve an accuracy of around 91%. The remaining articles explored in this SLR are attention mechanisms (10), RNN-LSTM (10), Large language models (LLM-10), and graph-based methods (4) with promising results. However, these methods also face certain limitations such as overfitting, risk of bias, and high data dependency that impact their performance. The review not only highlights the strengths and challenges of these methods but also suggests ways to handle them in the future to increase the accuracy and timely generation of medical reports.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Public concern regarding health systems has experienced a rapid surge during the last two years due to the COVID-19 outbreak. Accordingly, medical professionals and health-related institutions reach out to patients and seek feedback to analyze, monitor, and uplift medical services. Such views and perceptions are often shared on social media platforms like Facebook, Instagram, Twitter, etc. Twitter is the most popular and commonly used by the researcher as an online platform for instant access to real-time news, opinions, and discussion. Its trending hashtags (#) and viral content make it an ideal hub for monitoring public opinion on a variety of topics. The tweets are extracted using three hashtags #healthcare, #healthcare services, and #medical facilities. Also, location and tweet sentiment analysis are considered in this study. Several recent studies deployed Twitter datasets using ML and DL models, but the results show lower accuracy. In addition, the studies did not perform extensive comparative analysis and lack validation. This study addresses two research questions: first, what are the sentiments of people toward medical services worldwide? and second, how effective are the machine learning and deep learning approaches for the classification of sentiment on healthcare tweets? Experiments are performed using several well-known machine learning models including support vector machine, logistic regression, Gaussian naive Bayes, extra tree classifier, k nearest neighbor, random forest, decision tree, and AdaBoost. In addition, this study proposes a transfer learning-based LSTM-ETC model that effectively predicts the customer’s satisfaction level from the healthcare dataset. Results indicate that despite the best performance by the ETC model with an 0.88 accuracy score, the proposed model outperforms with a 0.95 accuracy score. Predominantly, the people are happy about the provided medical services as the ratio of the positive sentiments is substantially higher than the negative sentiments. The sentiments, either positive or negative, play a crucial role in making important decisions through customer feedback and enhancing quality.

El sector pesquero, más conocido como industria pesquera, es una parte del sector primario, o más bien una actividad económica e importante en el mundo, puesto que forma parte de la dieta del ser humano y de procesos industriales. Para llevar a cabo el proceso del pescado es necesariamente descongelarlo, esto se logra por medio de vapor sobrecalentado que se produce en una caldera la cual utiliza combustóleo como energía primaria, esto hace que aumente los costos de producción. Este trabajo tiene la finalidad de diseñar un sistema hibrido que sea eficiente, que reduzca los costos y aproveche la energía solar para el precalentamiento del agua. El sistema consiste en reducir el consumo de combustóleo aprovechando la energía térmica solar mediante tubos evacuados, el análisis del sistema se realizará por primera ley de la termodinámica, buscando la eficiencia del sistema, la cantidad de CO2 que dejan de exponerse a la atmósfera, los costos de implementación y el retorno de inversión de la propuesta.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The wheat crop that fulfills 35% of human food demand is facing several problems due to a lack of transparency, security, reliability, and traceability in the existing agriculture supply chain. Many systems have been developed for the agriculture supply chain to overcome such issues, however, monopolistic centralized control is the biggest hurdle to realizing the use of such systems. It has eventually gained consumers’ trust in branded products and rejected other products due to the lack of traceable supply chain information. This study proposes a blockchain-based framework for supply chain traceability which provides trustable, transparent, secure, and reliable services for the wheat crop. A crypto token called wheat coin (WC) has been introduced to keep track of transactions among the stakeholders of the wheat supply chain. Moreover, an initial coin offering (ICO) of WC, crypto wallets, and an economic model are proposed. Furthermore, a smart contract-based transaction system has been devised for the transparency of wheat crop transactions and conversion of WC to fiat and vice versa. We have developed the interplanetary file system (IPFS) to improve data availability, security, and transparency which stores encrypted private data of farmers, businesses, and merchants. Lastly, the results of the experiments show that the proposed framework shows better performance as compared to previous crop supply chain solutions in terms of latency to add-blocks, per-minute transactions, average gas charge for the transaction, and transaction verification time. Performance analysis with Bitcoin and Ethereum shows the superior performance of the proposed system.

Los granos de café son uno de los productos agrícolas más valiosos del mundo. El proceso de tostado es esencial para obtener de las mejores características organolépticas, teniendo en cuenta los patrones del flujo de aire y su relación con la temperatura dentro de la cámara de tostado. Para ello se realizó el estudio de la caracterización experimental y por simulación numérica del comportamiento térmico de una tostadora de café tipo tambor rotatorio de 2 kg por convección in-terna forzada. En la caracterización experimental se usó un kilo de café de la variedad Catuaí, manipulando cuatro velocidades medias por el ducto de entrada de aire a la cámara de tostado, que son los tratamientos de V0, V1, V2 y V3 con tres muestras por grupo. Realizaron la calificación organoléptica, 3 catadores certifica-dos de la empresa Narsa Innova de Chanchamayo-Perú. Con las muestras más representativas de cada grupo, se realizó el análisis estadístico de varianza de dos factores, encontrando que tiene influencia en la calificación organoléptica la variación de la velocidad del aire. También se encontró que el tratamiento V2 (2 m/s), tiene el promedio más alto de la calificación organoléptica con 83.21 puntos, con un tiempo total de tostado de 870 s y un tiempo de desarrollo de 120 s. Por otro lado, la caracterización numérica se realizó por transferencia de calor en estado transitorio, en un parasólido con arreglo matricial de los granos de 6×3×3, con una porosidad del 14.8 %, distribuidos dentro de un prisma rectangular. Aquí también encontramos las mejores condiciones de transferencia de calor para el tratamiento V2, donde los granos pasan los 195 °C cerca a los 600 s, con un tiempo de desarrollo suficiente para adquirir las mejores características organolépticas.

A efectos del cambio climático, a nivel mundial se genera una crisis del agua, la Ciudad de La Paz donde se sitúa Kañuma no es la excepción. Las reservas de agua dulce, disminuyen cada vez más por efectos del cambio climático, deforestación y consecuencia de la contaminación, incidiendo en la calidad y cantidad de agua potable, lo que obligará a implementar alternativas de captación de agua. En este sentido, los Large Fog Collectors (colectores de niebla) serán utilizados para captar agua del aire por medio de condensación, se emplazarán en el campus de la Universidad Privada Boliviana, elegida como centro de operaciones, serán los principales auspiciadores brindando el financiamiento en convenio con la Universidad de Illinois. El gradiente térmico en la zona escogida (Kañuma), se establecerá como un factor que favorece el efecto de condensación en gran magnitud. Los colectores de niebla, estarán compuesto por parantes y mallas Raschel. El uso de una estación meteorológica será clave para la determinación de los parámetros de cálculo y estimación para un buen diseño de LFC’s. Empleando el método científico de investigación, se implementará la Investigación formal Cuasi – Experimental, determinando las relaciones causa-efecto en la población de estudio. La única diferencia con una metodología experimental, estará delimitada en que las variables climatológicas del lugar no son controlables (velocidad del viento, porcentaje de sombra, temperatura, etc). Para el propósito se utilizarán distintos modelos de colectores de niebla, dos ubicados en un sector de mayor presión atmosférica, de geometría más larga que ancha y otro más ancho que largo, y con la misma disposición geométrica, otros dos en un sector de menor presión atmosférica. Se estima que se generará mayor volumen de agua captada cuando en la disposición geométrica, el largo sea mayor que el ancho.

University of La Romana > Research > Scientific Production Abierto Inglés Aim: The development of predictive models for patients treated by emergency medical services (EMS) is on the rise in the emergency field. However, how these models evolve over time has not been studied. The objective of the present work is to compare the characteristics of patients who present mortality in the short, medium and long term, and to derive and validate a predictive model for each mortality time. Methods: A prospective multicenter study was conducted, which included adult patients with unselected acute illness who were treated by EMS. The primary outcome was noncumulative mortality from all causes by time windows including 30-day mortality, 31- to 180-day mortality, and 181- to 365-day mortality. Prehospital predictors included demographic variables, standard vital signs, prehospital laboratory tests, and comorbidities. Results: A total of 4830 patients were enrolled. The noncumulative mortalities at 30, 180, and 365 days were 10.8%, 6.6%, and 3.5%, respectively. The best predictive value was shown for 30-day mortality (AUC = 0.930; 95% CI: 0.919–0.940), followed by 180-day (AUC = 0.852; 95% CI: 0.832–0.871) and 365-day (AUC = 0.806; 95% CI: 0.778–0.833) mortality. Discussion: Rapid characterization of patients at risk of short-, medium-, or long-term mortality could help EMS to improve the treatment of patients suffering from acute illnesses.

La mayoría de edificaciones de uso Educativo construidas en el Distrito de Iquitos, Provincia de Maynas, Departamento de Loreto, no cumplen con el Reglamento Nacional de Edificaciones, asimismo, con la Ley General de Salud, Ley N°26842 y de las 3 premisas básicas de la sustentabilidad, social y económica. La metodología utilizada para esta investigación, toma como muestra a los recintos de dos (02) edificaciones de uso educativo, ubicados en el Centro Urbano de la Ciudad de Iquitos, realizando el Diagnóstico situacional acústico de todos los ambientes, de las dos (02) instituciones educativas del presente estudio. Asimismo, la siguiente investigación evalúa algunas variables de las condiciones actuales de confort acústico que poseen las dos (02) Edificaciones de Uso Educativo. Por lo tanto, el interés social que ha motivado esta elección es que todas las edificaciones de uso Educativo mantienen el déficit de los diversos tipos de confort que se deben incorporar en los espacios arquitectónicos como es el higrotérmico, acústico, lumínico, olfativo, visual y psicológico. Específicamente para el análisis del confort acústico, ya que este caso ha generado problemas personales y familiares a la salud, provocando estrés y otras molestias, que resulta importante permanecer en entornos libres de ruidos molestos, insonorizando el medio ambiente, tapando el ruido proveniente de la calle o los sonidos generados al interior del espacio sin dejar que se filtren hacia el exterior, evitando que el ruido pase de un entorno a otro. Logrando que las ondas de los sonidos se reflejen o sean absorbidas por las superficies de la madera sin emitir ningún sonido desde el otro lado, ya que la madera tiene propiedades acústicas y térmicas inherentes que aumentan sus capacidades estructurales.

University of La Romana > Research > Scientific Production Abierto Inglés The classification of bird species is of significant importance in the field of ornithology, as it plays an important role in assessing and monitoring environmental dynamics, including habitat modifications, migratory behaviors, levels of pollution, and disease occurrences. Traditional methods of bird classification, such as visual identification, were time-intensive and required a high level of expertise. However, audio-based bird species classification is a promising approach that can be used to automate bird species identification. This study aims to establish an audio-based bird species classification system for 264 Eastern African bird species employing modified deep transfer learning. In particular, the pre-trained EfficientNet technique was utilized for the investigation. The study adapts the fine-tune model to learn the pertinent patterns from mel spectrogram images specific to this bird species classification task. The fine-tuned EfficientNet model combined with a type of Recurrent Neural Networks (RNNs) namely Gated Recurrent Unit (GRU) and Long short-term memory (LSTM). RNNs are employed to capture the temporal dependencies in audio signals, thereby enhancing bird species classification accuracy. The dataset utilized in this work contains nearly 17,000 bird sound recordings across a diverse range of species. The experiment was conducted with several combinations of EfficientNet and RNNs, and EfficientNet-B7 with GRU surpasses other experimental models with an accuracy of 84.03% and a macro-average precision score of 0.8342.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Predicting depression intensity from microblogs and social media posts has numerous benefits and applications, including predicting early psychological disorders and stress in individuals or the general public. A major challenge in predicting depression using social media posts is that the existing studies do not focus on predicting the intensity of depression in social media texts but rather only perform the binary classification of depression and moreover noisy data makes it difficult to predict the true depression in the social media text. This study intends to begin by collecting relevant Tweets and generating a corpus of 210000 public tweets using Twitter public application programming interfaces (APIs). A strategy is devised to filter out only depression-related tweets by creating a list of relevant hashtags to reduce noise in the corpus. Furthermore, an algorithm is developed to annotate the data into three depression classes: ‘Mild,’ ‘Moderate,’ and ‘Severe,’ based on International Classification of Diseases-10 (ICD-10) depression diagnostic criteria. Different baseline classifiers are applied to the annotated dataset to get a preliminary idea of classification performance on the corpus. Further FastText-based model is applied and fine-tuned with different preprocessing techniques and hyperparameter tuning to produce the tuned model, which significantly increases the depression classification performance to an 84% F1 score and 90% accuracy compared to baselines. Finally, a FastText-based weighted soft voting ensemble (WSVE) is proposed to boost the model’s performance by combining several other classifiers and assigning weights to individual models according to their individual performances. The proposed WSVE outperformed all baselines as well as FastText alone, with an F1 of 89%, 5% higher than FastText alone, and an accuracy of 93%, 3% higher than FastText alone. The proposed model better captures the contextual features of the relatively small sample class and aids in the detection of early depression intensity prediction from tweets with impactful performances.

Hoy en día, un medio a través del cual los Clientes interactúan con las Compañías son los conocidos Contact Centers o mejor llamados “Centros de Contacto”; éstos, tienen como objetivo brindar la atención a los Clientes sobre los Productos o Servicios que se ofrecen. La Tecnología IVR (Interactive Voice Response / Respuesta de Voz Interactiva) permite que los Clientes se puedan autoservir para poder realizar las Operaciones de su interés; por otro lado, ya sea a petición del propio Cliente o de la lógica del IVR, se puede realizar la transferencia de la llamada del Cliente hacia un Ejecutivo Telefónico y éste será quien le apoyará en las Operaciones solicitadas de una forma segura. La experiencia del cliente al usar el IVR es de suma relevancia; pues el IVR tiene como objetivo proveer de menús y opciones sencillas e intuitivas donde se brinden las Operaciones más relevantes hacia los Clientes. El presente trabajo está enfocado en el Desarrollo de un Modelo Predictivo usando Técnicas de Machine Learning (Aprendizaje Automático), el cual nos permitirá “predecir” la experiencia del Cliente al usar el IVR; o en otras palabras, entender que pasará si nuestra Empresa objeto de estudio sigue ofreciendo el mismo menú y opciones existentes hacia sus Clientes y si eso repercutirá en la experiencia que estos tienen y con esto, encontrar las áreas de oportunidad en esa interacción Cliente-IVR a través de éste canal de comunicación. La Experiencia del Cliente es de suma importancia, ya que, a través de esta es cómo los Clientes catalogan los productos y servicios que ofrece una empresa. El presente estudio, seguirá el método científico en sus distintas fases, a fin de dar el soporte necesario para el desarrollo de nuestro modelo.

El propósito de esta tesis es desarrollar un modelo para determinar la madurez digital de las Pymes manufactureras del Estado de Nuevo León considerando su heterogeneidad, necesidades organizacionales y tecnológicas, así como proponer estrategias de avance en su transformación digital. Primero se consultó la literatura actualizada en diferentes bases de datos, referente al tema de la Industria 4.0 y la transformación digital, su contexto a nivel internacional, nacional y en Nuevo León y los principales modelos, teorías y metodologías de maduración digital en las organizaciones. A partir de ello se construyó el marco teórico de la variable dependiente grado de madurez digital y se definieron las variables independientes capacidad de absorción del conocimiento, nivel de infraestructura tecnológica, cultura organizacional, capacidad de in-novación y entorno de la empresa con base en los factores que influyen en la madurez digital. Posteriormente se diseñó un modelo preliminar de madurez digital para las Pymes manufactureras de Nuevo León que incluyó dos instrumentos de medición cuantitativa y cualitativa, encuesta y entrevista semi-estructurada, los cuales fueron analizados por expertos y aplicados a una muestra piloto para comprobar su fiabilidad. Después se aplicó a la muestra total seleccionada para obtener los datos que se analizaron usando métodos estadísticos de regresión lineal múltiple para evaluar las variables. Adicionalmente se obtuvieron los retos y oportunidades a los que se enfrentan las Pymes en su avance en la transformación digital, la aplicación de las tecnologías digitales en sus productos, servicios y procesos, y los habilitadores e inhibidores que influyen en su madurez digital. Como resultado se generó el modelo de medición de madurez digital para las Pymes manufactureras del Estado de Nuevo León, así como un marco general de estrategias para la transformación digital que favorece la competitividad de estas organizaciones en las cadenas de valor regionales y globales.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés With the outbreak of the COVID-19 pandemic, social isolation and quarantine have become commonplace across the world. IoT health monitoring solutions eliminate the need for regular doctor visits and interactions among patients and medical personnel. Many patients in wards or intensive care units require continuous monitoring of their health. Continuous patient monitoring is a hectic practice in hospitals with limited staff; in a pandemic situation like COVID-19, it becomes much more difficult practice when hospitals are working at full capacity and there is still a risk of medical workers being infected. In this study, we propose an Internet of Things (IoT)-based patient health monitoring system that collects real-time data on important health indicators such as pulse rate, blood oxygen saturation, and body temperature but can be expanded to include more parameters. Our system is comprised of a hardware component that collects and transmits data from sensors to a cloud-based storage system, where it can be accessed and analyzed by healthcare specialists. The ESP-32 microcontroller interfaces with the multiple sensors and wirelessly transmits the collected data to the cloud storage system. A pulse oximeter is utilized in our system to measure blood oxygen saturation and body temperature, as well as a heart rate monitor to measure pulse rate. A web-based interface is also implemented, allowing healthcare practitioners to access and visualize the collected data in real-time, making remote patient monitoring easier. Overall, our IoT-based patient health monitoring system represents a significant advancement in remote patient monitoring, allowing healthcare practitioners to access real-time data on important health metrics and detect potential health issues before they escalate.

Our system is comprised of a hardware component that collects and transmits data from sensors to a cloud-based storage system, where it can be accessed and analyzed by healthcare specialists. The ESP-32 microcontroller interfaces with the multiple sensors and wirelessly transmits the collected data to the cloud storage system. A pulse oximeter is utilized in our system to measure blood oxygen saturation and body temperature, as well as a heart rate monitor to measure pulse rate. A web-based interface is also implemented, allowing healthcare practitioners to access and visualize the collected data in real-time, making remote patient monitoring easier. Overall, our IoT-based patient health monitoring system represents a significant advancement in remote patient monitoring, allowing healthcare practitioners to access real-time data on important health metrics and detect potential health issues before they escalate.

Ibero-american International University > Research > Articles and Books Abierto Inglés Retinitis pigmentosa (RP) is a group of genetic retinal disorders characterized by progressive vision loss, culminating in blindness. Identifying pigment signs (PS) linked with RP is crucial for monitoring and possibly slowing the disease’s degenerative course. However, the segmentation and detection of PS are challenging due to the difficulty of distinguishing between PS and blood vessels and the variability in size, shape, and color of PS. Recently, advances in deep learning techniques have shown impressive results in medical image analysis, especially in ophthalmology. This study presents an approach for classifying pigment marks in color fundus images of RP using a modified squeeze-and-excitation ResNet (SE-ResNet) architecture. This variant synergizes the efficiency of residual skip connections with the robust attention mechanism of the SE block to amplify feature representation. The SE-ResNet model was fine-tuned to determine the optimal layer configuration that balances performance metrics and computational costs. We trained the proposed model on the RIPS dataset, which comprises images from patients diagnosed at various RP stages. Experimental results confirm the efficacy of the proposed model in classifying different types of pigment signs associated with RP. The model yielded performance metrics, such as accuracy, sensitivity, specificity, and f-measure of 99.16%, 97.70%, 96.93%, 90.47%, 99.37%, 97.80%, 97.44%, and 90.60% on the testing set, based on GT1 & GT2 respectively. Given its performance, this model is an excellent candidate for integration into computer-aided diagnostic systems for RP, aiming to enhance patient care and vision-related healthcare services.

At varying stages of requirement specification, multiple ambiguities emerge. Ambiguities may appear at several levels including the syntactic, semantic, domain, lexical, and pragmatic levels. The primary objective of this study is to identify requirements’ pragmatic ambiguity. Pragmatic ambiguity occurs when the same set of circumstances can be interpreted in multiple ways. It requires consideration of the context statement of the requirements. Prior research has developed methods for obtaining concepts based on individual nodes, so there is room for improvement in the requirements interpretation procedure. This research aims to develop a more effective model for identifying pragmatic ambiguity in requirement definition. To better interpret requirements, we introduced the Concept Maximum Matching (CMM) technique, which extracts concepts based on edges. The CMM technique significantly improves precision because it permits a more accurate interpretation of requirements based on the relative weight of their edges. Obtaining an F-measure score of 0.754 as opposed to 0.563 in existing models, the evaluation results demonstrate that CMM is a substantial improvement over the previous method.

University of La Romana > Research > Scientific Production Abierto Inglés Non-Insulin-Dependent Diabetes Mellitus (NIDDM) is a chronic health condition caused by high blood sugar levels, and if not treated early, it can lead to serious complications i.e. blindness. Human Activity Recognition (HAR) offers potential for early NIDDM diagnosis, emerging as a key application for HAR technology. This research introduces DiabSense, a state-of-the-art smartphone-dependent system for early staging of NIDDM. DiabSense incorporates HAR and Diabetic Retinopathy (DR) upon leveraging the power of two different Graph Neural Networks (GNN). HAR uses a comprehensive array of 23 human activities resembling Diabetes symptoms, and DR is a prevalent complication of NIDDM. Graph Attention Network (GAT) in HAR achieved 98.32% accuracy on sensor data, while Graph Convolutional Network (GCN) in the Aptos 2019 dataset scored 84.48%, surpassing other state-of-the-art models. The trained GCN analyzed retinal images of four experimental human subjects for DR report generation, and GAT generated their average duration of daily activities over 30 days. The daily activities in non-diabetic periods of diabetic patients were measured and compared with the daily activities of the experimental subjects, which helped generate risk factors. Fusing risk factors with DR conditions enabled early diagnosis recommendations for the experimental subjects despite the absence of any apparent symptoms. The comparison of DiabSense system outcome with clinical diagnosis reports in the experimental subjects was conducted using the A1C test. The test results confirmed the accurate assessment of early diagnosis requirements for experimental subjects by the system. Overall, DiabSense exhibits significant potential for ensuring early NIDDM treatment, improving millions of lives worldwide.

University of La Romana > Research > Scientific Production Abierto Inglés Objective Epileptic seizures are neurological events that pose significant risks of physical injuries characterized by sudden, abnormal bursts of electrical activity in the brain, often leading to loss of consciousness and uncontrolled movements. Early seizure detection is essential for timely treatments and better patient outcomes. To address this critical issue, there is a need for an advanced artificial intelligence approach for the early detection of epileptic seizure disorder. Methods This study primarily focuses on designing a novel ensemble approach to perform early detection of epileptic seizure disease with high performance. A novel ensemble approach consisting of a fast, independent component analysis random forest (FIR) and prediction probability is proposed, which uses electroencephalography (EEG) data to investigate the efficacy of the proposed approach for early detection of epileptic seizures. The FIR model extracts independent components and class prediction probability features, creating a new feature set. The proposed model combined integrated component analysis (ICA) with predicting probability to enhance seizure recognition accuracy scores. Extensive experimental evaluations demonstrate that FIR assists machine learning models to obtain superior results compared to original features. Results The research gap is addressed using combined features to improve the performance of epileptic seizure detection compared to a single feature set. In particular, the ensemble model FIR with support vector machine (FIR + SVM) outperforms other methods, achieving an accuracy of 98.4% for epileptic seizure detection. Conclusions The proposed FIR has the potential for early diagnosis of epileptic seizures and can significantly help the medical industry with enhanced detection and timely interventions.

Con la globalización son muchos los retos a los que diferentes organizaciones se enfrentan cada día para sobrevivir en el acelerado y competitivo mercado mundial, apostando por la innovación o las más disruptivas técnicas que garanticen el éxito de sus proyectos. Es por ello que la presente investigación busca dar a conocer los efectos de la llamada revolución industrial 4.0 y sus diferentes tecnologías en la gestión tradicional de proyectos, analizando el impacto en sus distintas fases, así como en los roles o perfiles involucrados en cada una.Para entender esta evolución se analizarán los cambios tecnológicos de nuestra historia contemporánea, desde la primera revolución industrial, que representó una transición entre la producción manual a la mecanización, reinventando la cultura de trabajo (Romano et al. 2017); hasta finalmente llegar a los avances tecnológicos actuales. Sobre esto últimos, se analizarán tendencias y su relación con la gestión de proyectos, advirtiendo retos, como el uso de habilidades amplias como la Inteligencia Artificial (AI), inteligencia extendida (EI), y la robótica; todo bajo un esquema de análisis cualitativo que considerará todos los datos obtenidos entendiendo que la gestión de proyectos ha sido una disciplina empresarial crítica con los años y con los constantes cambios sociales, ambientales, económicos y tecnológicos en el horizonte se hace necesario considerar cómo estos cambios afectarán la forma en que las organizaciones administran y ejecutan los proyectos. (Browniee, 2019) Por lo que se podría esperar cambios en roles y estructuras de la gestión de proyectos de la mano de inteligencias artificiales y tecnologías altamente dotadas que reduzcan los tiempos de entregas, minimicen los riesgos y garanticen una máxima eficiencia que hasta ahora no era posible, para lo cual se gestor de proyectos tendría que adaptarse técnicamente.

University of La Romana > Research > Scientific Production Abierto Inglés Malaria is an extremely malignant disease and is caused by the bites of infected female mosquitoes. This disease is not only infectious among humans, but among animals as well. Malaria causes mild symptoms like fever, headache, sweating and vomiting, and muscle discomfort; severe symptoms include coma, seizures, and kidney failure. The timely identification of malaria parasites is a challenging and chaotic endeavor for health staff. An expert technician examines the schematic blood smears of infected red blood cells through a microscope. The conventional methods for identifying malaria are not efficient. Machine learning approaches are effective for simple classification challenges but not for complex tasks. Furthermore, machine learning involves rigorous feature engineering to train the model and detect patterns in the features. On the other hand, deep learning works well with complex tasks and automatically extracts low and high-level features from the images to detect disease. In this paper, EfficientNet, a deep learning-based approach for detecting Malaria, is proposed that uses red blood cell images. Experiments are carried out and performance comparison is made with pre-trained deep learning models.

University of La Romana > Research > Scientific Production Abierto Inglés Malaria is an extremely malignant disease and is caused by the bites of infected female mosquitoes. This disease is not only infectious among humans, but among animals as well. Malaria causes mild symptoms like fever, headache, sweating and vomiting, and muscle discomfort; severe symptoms include coma, seizures, and kidney failure. The timely identification of malaria parasites is a challenging and chaotic endeavor for health staff. An expert technician examines the schematic blood smears of infected red blood cells through a microscope. The conventional methods for identifying malaria are not efficient. Machine learning approaches are effective for simple classification challenges but not for complex tasks. Furthermore, machine learning involves rigorous feature engineering to train the model and detect patterns in the features. On the other hand, deep learning works well with complex tasks and automatically extracts low and high-level features from the images to detect disease. In this paper, EfficientNet, a deep learning-based approach for detecting Malaria, is proposed that uses red blood cell images. Experiments are carried out and performance comparison is made with pre-trained deep learning models. In addition, k-fold cross-validation is also used to substantiate the results of the proposed approach. Experiments show that the proposed approach is 97.57% accurate in detecting Malaria from red blood cell images and can be beneficial practically for medical healthcare staff.

According to the World Business Council for Sustainable Development (WBCSD), the built environment contributes around 10 % of global GDP but is also a major source of emissions, land use, and resource consumption. The built environment also consumes one-third of global energy and produces 40 % of greenhouse gas (GHG) emissions. The United Nations has set up the 2030 Sustainable Development Goals (SDGs), which emphasize the significance of transforming the built environment to cope with issues such as net-zero emissions, resilient infrastructure, circular economy, health, etc. Researchers have emphasized that digitalization is one of the factors that can meet the aforementioned targets in a built environment with a sustainability aspect. Digitalization in any field is realized with the assimilation of Industry 4.0 enabling technologies with sustainably built infrastructure. It has been identified that; there are limited studies where all Industry 4.0 enabling technologies are detailed discussed. Based upon the above facts, this study aims to analyze and identify the progress of distinct Industry 4.0 enabling technologies including the Internet of Things (IoT), Cloud Computing, Edge Computing/Fog Computing, Big Data Analytics, Artificial Intelligence (AI), Machine Learning (ML), Blockchain, Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR), Digital Twin, Metaverse, and Robotics implementation in the built environment.

University of La Romana > Research > Scientific Production Abierto Inglés Thyroid illness encompasses a range of disorders affecting the thyroid gland, leading to either hyperthyroidism or hypothyroidism, which can significantly impact metabolism and overall health. Hypothyroidism can cause a slowdown in bodily processes, leading to symptoms such as fatigue, weight gain, depression, and cold sensitivity. Hyperthyroidism can lead to increased metabolism, causing symptoms like rapid weight loss, anxiety, irritability, and heart palpitations. Prompt diagnosis and appropriate treatment are crucial in managing thyroid disorders and improving patients’ quality of life. Thyroid illness affects millions worldwide and can significantly impact their quality of life if left untreated. This research aims to propose an effective artificial intelligence-based approach for the early diagnosis of thyroid illness. An open-access thyroid disease dataset based on 3,772 male and female patient observations is used for this research experiment. This study uses the nominal continuous synthetic minority oversampling technique (SMOTE-NC) for data balancing and a fine-tuned light gradient booster machine (LGBM) technique to diagnose thyroid illness and handle class imbalance problems. The proposed SNL (SMOTE-NC-LGBM) approach outperformed the state-of-the-art approach with high-accuracy performance scores of 0.96. We have also applied advanced machine learning and deep learning methods for comparison to evaluate performance. Hyperparameter optimizations are also conducted to enhance thyroid diagnosis performance. In addition, we have applied the explainable Artificial Intelligence (XAI) mechanism based on Shapley Additive exPlanations (SHAP) to enhance the transparency and interpretability of the proposed method by analyzing the decision-making processes. The proposed research revolutionizes the diagnosis of thyroid disorders efficiently and helps specialties overcome thyroid disorders early.

University of La Romana > Research > Scientific Production Abierto Inglés Humans can carry various diseases, some of which are poorly understood and lack comprehensive solutions. Such a disease can exists in human eye that can affect one or both eyes is diabetic retinopathy (DR) which can impair function, vision, and eventually result in permanent blindness. It is one of those complex complexities. Therefore, early detection of DR can significantly reduce the risk of vision impairment by appropriate treatment and necessary precautions. The primary aim of this study is to leverage cutting-edge models trained on diverse image datasets and propose a CNN model that demonstrates comparable performance. Specifically, we employ transfer learning models such as DenseNet121, Xception, Resnet50, VGG16, VGG19, and InceptionV3, and machine learning models such as SVM, and neural network models like (RNN) for binary and multi-class classification. It has been shown that the proposed approach of multi-label classification with softmax functions and categorical cross-entropy works more effectively, yielding perfect accuracy, precision, and recall values. In particular, Xception achieved an impressive 82% accuracy among all the transfer learning models, setting a new benchmark for the dataset used. However, our proposed CNN model shows superior performance, achieving an accuracy of 95.27% on this dataset, surpassing the state-of-the-art Xception model. Moreover, for single-label (binary classifications), our proposed model achieved perfect accuracy as well. Through exploration of these advances, our objective is to provide a comprehensive overview of the leading methods for the early detection of DR. The aim is to discuss the challenges associated with these methods and highlight potential enhancements.

This article investigates the influence of process and geometric parameters on deformation during mild steel Submerged arc welding (SAW). This article focuses on optimizing welding process parameters to reduce distortion and improve product quality. The intent of this study is to investigate the effects of technical and geometrical parameters on deformation during submerged arc welding of mild steel using ANSYS and experimental values employing element type brick 8 node 70. The temperature distribution was analyzed using the double ellipsoidal heat source model developed by Goldak, and the amount of deformation was predicted by changing the plate thickness, welding speed and current. The finite element method (FEM) was used to simulate the welding process and obtain an approximate solution. ANSYS software was used for modeling and analysis. The effect of four main parameters of the series (A, B, C, D) on the distortion was analyzed. The simulation results were compared with the experimental values. The study revealed that the maximum distortion determined for SET A was 1.341 mm, corresponding to the experimental value of 1.20 mm. SET B resulted in a maximum distortion of 0.88 mm, corresponding to an experimental value of 0.60 mm. The increase in heat-input in SET C increased the strain/distortion from 1.341 to 2.989 mm, which closely matches the experimental value of 2.60 mm. Increasing the welding speed for SET D reduces the deformation from 2.989 to 2.230 mm, in good agreement with the experimental value of 2.012 mm. SET E investigated the effect of different plate thicknesses on deformation, and the thicker the plate, the lower the maximum deformation. This research can aid in the optimization of welding process parameters and the reduction of distortion in the finished product by forecasting the maximum distortion by varying these parameters. The novelty of this study lies in its investigation of the influence of various variables on the welding process and the distortion that results, which has the potential to significantly enhance the welding process and the caliber of the final product. The findings of this study can be applied in the shipbuilding and automotive industries.

This study explored the impact of varying weight percentages of TiMoVWCr high-entropy alloy (HEA) powder addition on A356 composites produced using friction stir processing (FSP). Unlike previous research that often focused on singular aspects, such as mechanical properties, or microstructural analysis, this investigation systematically examined the multifaceted performance of A356 composites by comprehensively assessing the microstructure, interfacial bonding strength, mechanical properties, and wear behavior. The study identified a uniform distribution of TiMoVWCr HEA powder in the composition A356/2%Ti2%Mo2%V2%W2%Cr, highlighting the effectiveness of the FSP technique in achieving homogeneous dispersion. Strong bonding between the reinforcement and matrix material was observed in the same composition, indicating favorable interfacial characteristics. Mechanical properties, including tensile strength and hardness, were evaluated for various compositions, demonstrating significant improvements across the board. The addition of 2%Ti2%Mo2%V2%W2%Cr powder enhanced the tensile strength by 36.39%, while hardness improved by 62.71%. Similarly, wear resistance showed notable enhancements ranging from 35.56 to 48.89% for different compositions. Microstructural analysis revealed approximately 1640.59 grains per square inch for the A356/2%Ti2%Mo2%V2%W2%Cr processed composite at 500 magnifications. In reinforcing Al composites with Ti, Mo, V, W, and Cr high-entropy alloy (HEA) particles, each element imparted distinct benefits. Titanium (Ti) enhanced strength and wear resistance, molybdenum (Mo) contributed to improved hardness, vanadium (V) promoted hardenability, tungsten (W) enhanced wear resistance, and chromium (Cr) provided wear resistance and hardness. Anticipating the potential applications of the developed composite, the study suggests its suitability for the aerospace sector, particularly in casting lightweight yet high-strength parts such as aircraft components, engine components, and structural components, underlining the significance of the investigated TiMoVWCr HEA powder-modified A356 composites.

Subjects > Social Sciences Ibero-american International University > Research > Doctoral Thesis Cerrado Español La competencia global y el entorno turbulento ha provocado cambios fundamentales en el entorno competitivo de las industrias manufactureras, obligándolas a revisar sus procesos productivos, reducir costos operativos y ser más eficientes en el uso de sus recursos. Las organizaciones desean encontrar la fórmula con la mejor estrategia para el logro de sus objetivos y a menudo sufren de la escasez de una metodología sistemática y consistente. Los metas claves son lograr cero desperdicios, cero inventarios, cero defectos, cero paros y cero accidentes. En este sentido organizaciones han implementado metodologías o nuevos sistemas de gestión integral de manufactura para mejorar simultáneamente su rendimiento. El World Class Manufacturing es un sistema de gestión integral de operaciones de manufactura creado por el Dr. Hajime Yamashina en conjunto con algunas corporaciones multinacionales y el WCM Association. El sistema es una de las estrategias más innovadoras creadas para mejorar integralmente las organizaciones, ya que su metodología permite determinar las necesidades específicas financieras de la organización, permite priorizar las acciones basadas en estas necesidades y así focalizar los recursos directamente a estas necesidades.

Subjects > Social Sciences Ibero-american International University > Research > Doctoral Thesis Cerrado Español La competencia global y el entorno turbulento ha provocado cambios fundamentales en el entorno competitivo de las industrias manufactureras, obligándolas a revisar sus procesos productivos, reducir costos operativos y ser más eficientes en el uso de sus recursos. Las organizaciones desean encontrar la fórmula con la mejor estrategia para el logro de sus objetivos y a menudo sufren de la escasez de una metodología sistemática y consistente. Los metas claves son lograr cero desperdicios, cero inventarios, cero defectos, cero paros y cero accidentes. En este sentido organizaciones han implementado metodologías o nuevos sistemas de gestión integral de manufactura para mejorar simultáneamente su rendimiento. El World Class Manufacturing es un sistema de gestión integral de operaciones de manufactura creado por el Dr. Hajime Yamashina en conjunto con algunas corporaciones multinacionales y el WCM Association. El sistema es una de las estrategias más innovadoras creadas para mejorar integralmente las organizaciones, ya que su metodología permite determinar las necesidades específicas financieras de la organización, permite priorizar las acciones basadas en estas necesidades y así focalizar los recursos directamente a estas necesidades. Sus técnicas se basan en el concepto de cero residuos, cero paros operativos, cero defectos y cero inventarios. Esta estrategia se vuelve adecuada para empresas que buscan minimizar los costos de sus actividades, aumentar su excelencia y, por lo tanto, la competitividad en todos los sectores. Tomando como base los datos estadísticos económicos en México y la importancia que tiene el sector automotriz en la economía se pretende detallar cuales los factores críticos de éxito que afectan la implementación exitosa del World Class Manufacturing en organizaciones automotrices en México.

University of La Romana > Research > Scientific Production Abierto Inglés In contemporary society, depression has emerged as a prominent mental disorder that exhibits exponential growth and exerts a substantial influence on premature mortality. Although numerous research applied machine learning methods to forecast signs of depression. Nevertheless, only a limited number of research have taken into account the severity level as a multiclass variable. Besides, maintaining the equality of data distribution among all the classes rarely happens in practical communities. So, the inevitable class imbalance for multiple variables is considered a substantial challenge in this domain. Furthermore, this research emphasizes the significance of addressing class imbalance issues in the context of multiple classes. We introduced a new approach Feature group partitioning (FGP) in the data preprocessing phase which effectively reduces the dimensionality of features to a minimum. This study utilized synthetic oversampling techniques, specifically Synthetic Minority Over-sampling Technique (SMOTE) and Adaptive Synthetic (ADASYN), for class balancing. The dataset used in this research was collected from university students by administering the Burn Depression Checklist (BDC). For methodological modifications, we implemented heterogeneous ensemble learning stacking, homogeneous ensemble bagging, and five distinct supervised machine learning algorithms. The issue of overfitting was mitigated by evaluating the accuracy of the training, validation, and testing datasets. To justify the effectiveness of the prediction models, balanced accuracy, sensitivity, specificity, precision, and f1-score indices are used. Overall, comprehensive analysis demonstrates the discrimination between the Conventional Depression Screening (CDS) and FGP approach. In summary, the results show that the stacking classifier for FGP with SMOTE approach yields the highest balanced accuracy, with a rate of 92.81%. The empirical evidence has demonstrated that the FGP approach, when combined with the SMOTE, able to produce better performance in predicting the severity of depression. Most importantly the optimization of the training time of the FGP approach for all of the classifiers is a significant achievement of this research.

Le Cameroun, situé en Afrique centrale, joue un rôle de premier plan en termes d'échanges, avec environ la moitié du PIB de la zone de la Commission économique et monétaire de l'Afrique centrale. Pourtant, la qualité des dépenses publiques au Cameroun serait l'un des griefs qui pèsent sur sa croissance économique. Cette sous-performance est généralement liée à la gestion de projets, levier essentiel pour le développement du pays. La construction d'infrastructures est l'un des enjeux de la politique de développement du Cameroun. Les acteurs de mise en œuvre des projets ont une faible maîtrise de la préparation des projets d’investissement public. Cette carence des acteurs dans la connaissance et la pratique de la maturation a un impact énorme dans la consommation des crédits et l'exécution des projets qui entraîne inévitablement l'abandon des projets, la multiplication des avenants, la malfaçon et le manque de satisfaction de la part des bénéficiaires. Ainsi, après avoir effectué une analyse SWOT de la maturité des projets d’investissement public camerounais, cette étude explore 191 projets (17 grands projets de première génération et 174 projets du programme PLANUT) entrepris au cours de la dernière décennie, afin de sonder l’influence de la maturation des projets sur le délai, le coût et la qualité. Les résultats du test d'hypothèses à l'aide de l'analyse de corrélation de Spearman ont révélé que des quinze hypothèses énoncées, treize ont été acceptées. Il ressort également que le niveau général de maturité de cette étude était respectivement de 68 % et 26% pour les deux groupes de l’échantillon étudié. Le niveau de maturité d'un projet d'investissement public au Cameroun affecte positivement sa livraison, alors que certaines variables de maturité n'expliquent pas significativement les coûts avec certains paramètres, mais influencent d'autres. Des recommandations pour une meilleure gestion des projets dans le pays sont énoncées.

En el año 2008 se realizó la transferencia en la que se asumieron las competencias de la Administración de Justicia en Cantabria (España) y se inició el reto de digitalizar dicha administración para dar un salto tecnológico al siglo XXI.El problema a afrontar era cómo planificar y ejecutar un plan de acción de mejora tecnológica en el complejo entorno de la administración de justicia de Cantabria, para alcanzar el expediente judicial electrónico. La problemática no radica únicamente en el complejo entorno en que se ha de realizar la modernización tecnológica, sino la situación socio cultural en que se realiza (limitaciones de tiempo tanto por la necesidad política de obtener resultados a corto-medio plazo como por la necesidad de justificar las inversiones en base al proyecto de ayudas europeas). El proceso requería actuaciones a diferentes niveles: organizativos, estratégicos, tecnológicos y humanos. En base a la problemática presentada se emplean metodologías acordes a la necesidad; para definir la estructura del grupo de toma de decisiones, se establecen metodologías de decisión de grupo y metodología en la conducción de reuniones para la operación eficaz de grupos de trabajo; para los desarrollos, despliegues y seguimiento de los proyectos tecnológicos desplegados se emplea la meto-dología ISO/IEC 21500:2013 (ISO, 2013), SCRUM y el modelo Cascada (para definir el modelo organizacional de justicia de forma lógica). Por último, para el análisis de los datos obtenidos se usa análisis estadístico descriptivo para valorar la eficacia/eficiencia del procedimiento implementado, el método Rash para analizar la percepción de los usuarios acerca del sistema implementado, el método ANOVA para comparar la variabilidad dentro de cada grupo con la variabilidad entre los grupos y el método de clusterización para identificar grupos con percepciones valorativas similares.Con la culminación del proyecto se ha demostrado un aumento de la transparencia, eficacia y eficiencia de los órganos judiciales, se han reducido los tiempos en la resolución de asuntos, se ha logrado garantizar la interoperabilidad entre órganos judiciales y profesionales y se ha conseguido un aumento de la satisfacción de los usuarios con el servicio prestado.

La gestión del mantenimiento es una tarea crucial en las organizaciones empresariales, ya que garantiza la eficiencia del negocio, la protección del medio ambiente y la seguridad de los activos físicos. Para lograrlo, se requiere de la gestión adecuada de recursos, conocimientos, talento humano, cronogramas, riesgos y procesos necesarios, aplicando cualquiera de los modelos de mantenimiento más comunes, como (TPM , RCM , WCM ). Sin embargo, para las IPS en Cúcuta, Colombia, esta tarea puede resultar especialmente difícil debido a la falta de metodologías específicas y a la gran cantidad de activos críticos a mantener. Por esta razón, se llevó a cabo una investigación con el objetivo de diseñar una Guía Metodológica híbrida entre RCM y PMBOK para la gestión de mantenimiento de equipos biomédicos críticos en IPS de mediana complejidad en Cúcuta. La investigación incluyó la caracterización de las normativas, variables, procesos e indicadores relacionados; el diseño de la guía metodológica híbrida; y un análisis comparativo de los resultados y validación final por expertos. Para recopilar información se utilizaron instrumentos evaluativos basados en normas vigentes y en un instrumento diagnóstico de cumplimiento de la guía metodológica. Los datos y resultados obtenidos se analizaron mediante ponderación, pruebas de hipótesis y juicio de expertos, lo que llevó a la creación de una guía Metodológica resultante permite a las IPS de mediana complejidad en Cúcuta tener un enfoque más proactivo en la gestión del mantenimiento de equipos biomédicos críticos, reduciendo los costos asociados con la reparación y reemplazo de equipos, así como los costos indirectos asociados con la interrupción del servicio de salud. En resumen, esta investigación destaca la importancia de la gestión del mantenimiento en las organizaciones empresariales y su impacto en la eficiencia del negocio y la seguridad de los activos físicos

University of La Romana > Research > Scientific Production Abierto Inglés Wafer mappings (WM) help diagnose low-yield issues in semiconductor production by offering vital information about process anomalies. As integrated circuits continue to grow in complexity, doing efficient yield analyses is becoming more essential but also more difficult. Semiconductor manufacturers require constant attention to reliability and efficiency. Using the capabilities of convolutional neural network (CNN) models improved by hierarchical attention module (HAM), wafer hotspot detection is achieved throughout the fabrication process. In an effort to achieve accurate hotspot detection, this study examines a variety of model combinations, including CNN, CNN+long short-term memory (LSTM) LSTM, CNN+Autoencoder, CNN+artificial neural network (ANN), LSTM+HAM, Autoencoder+HAM, ANN+HAM, and CNN+HAM. Data augmentation strategies are utilized to enhance the model’s resilience by optimizing its performance on a variety of datasets. Experimental results indicate a superior performance of 94.58% accuracy using the CNN+HAM model. K-fold cross-validation results using 3, 5, 7, and 10 folds indicate mean accuracy of 94.66%, 94.67%, 94.66%, and 94.66%, for the proposed approach, respectively. The proposed model performs better than recent existing works on wafer hotspot detection. Performance comparison with existing models further validates its robustness and performance.

University of La Romana > Research > Scientific Production Abierto Inglés Nanotechnology has opened new avenues for advanced research in various fields of soft materials. Materials scientists, chemists, physicists, and computational mathematicians have begun to take a keen interest in soft materials due to their potential applications in nanopatterning, membrane separation, drug delivery, nanolithography, advanced storage media, and nanorobotics. The unique properties of soft materials, particularly self-assembly, have made them useful in fields ranging from nanotechnology to biomedicine. The discovery of new morphologies in the diblock copolymer system in curved geometries is a challenging problem for mathematicians and theoretical scientists. Structural frustration under the effects of confinement in the system helps predict new structures. This mathematical study evaluates the effects of confinement and curvature on symmetric diblock copolymer melt using a cell dynamic simulation model. New patterns in lamella morphologies are predicted. The Laplacian involved in the cell dynamic simulation model is approximated by generating a 17-point stencil discretized to a polar grid by the finite difference method. Codes are programmed in FORTRAN to run the simulation, and IBM open DX is used to visualize the results.

La valuación inmobiliaria es una base fundamental en el quehacer de la dinámica económica en los bienes raíces. Para conocer el valor de los inmuebles es necesario realizar un análisis de los factores que, de acuerdo con las características propias y condiciones particulares de cada ubicación, son los que aglutinan el valor final. Los procedimientos son variables y en este trabajo se propone una metodología novedosa que involucra la aplicación de la fórmula de la interacción urbana para llevar a cabo este análisis en la Ciudad de San Salvador. Los componentes intrínsecos que conforman el valor inmobiliario están relacionados con cada una de las variables que lo afectan y estos dependen de la ubicación relativa y del entorno económico-temporal. Para su cálculo se obtuvo la magnitud de la relatividad existente entre el activo sujeto, el punto de interés y el referente del cual conocemos su magnitud. Las magnitudes de la variable independiente se obtuvieron a partir del estudio de mercado en forma de función matemática. La variable dependiente fue la magnitud alcanzada relativa a la distancia de relación entre la ubicación del referente y el nodo urbano; además se analizaron las magnitudes del tamaño del predio, ubicación en la manzana, infraestructura de servicios y la seguridad, cuya composición de variables conformó el valor hedónico. La aplicación de la interacción urbana dio como resultado el dimensionamiento del valor unitario del suelo para una ubicación en especial. Se generó también un mapa en línea con gráficos que facilitan el análisis de sectores con la información recabada.

Ibero-american International University > Research > Articles and Books Abierto Inglés Diabetic retinopathy (DR) can be defined as visual impairment caused by prolonged diabetes affecting the blood vessels in the retina. Globally, it stands as the primary contributor to blindness, impacting approximately 191 million individuals. While prior research has addressed DR classification using retinal fundus images, existing methods often focus on isolated lesion detection, lacking a comprehensive framework for the simultaneous identification of all lesions. Previous studies concentrated on early-stage features like exudates, aneurysms, hemorrhages, and blood vessels, sidelining severe-stage lesions such as cotton wool spots, venous beading, very severe intraretinal microvascular abnormalities (IRMA), diffuse intraretinal hemorrhages, capillary degeneration, highly activated microglia, and retinal pigment epithelium (RPE) damage. In this study, a deep learning approach is proposed to classify DR fundus images by severity levels, utilizing GoogleNet and ResNet models based on adaptive particle swarm optimizer (APSO), for enhanced feature extraction. The extracted features from the hybrid model are further used with different machine learning models like random forest, support vector machine, decision tree, and linear regression models. Experimental results showcased the proposed hybrid framework outperforming advanced approaches with a remarkable 94% accuracy on the benchmark dataset. This method demonstrates potential enhancements in precision, recall, accuracy, and F1 score for different DR severity levels.

Ibero-american International University > Research > Articles and Books Cerrado Inglés An extensive examination reveals that Wireless Sensor Networks (WSNs) offer a promising solution for essential sensing and event-driven data communication needs. WSNs hold significant potential for event-driven communication, primarily owing to their decentralized and infrastructure-free operational characteristics. However, the traditional WSN’s inherent static nature imposes limitations on its applicability, particularly in scenarios requiring generic operating characteristics or routing protocols for Vehicle-to-Vehicle (V2V) communication. This constraint arises from the immobility of sensor nodes within the network. Nonetheless, adopting a forward-looking perspective that incorporates mobility into WSNs opens up opportunities to create a mobile-WSN solution tailored for V2V communication. In response to the challenges posed by mobile-WSNs and the pursuit of a cost-effective V2V communication solution, a Lightweight Energy-Efficient Cross-layer Routing (LRECR) scheme has been proposed for WSN-VANET-based networks. The proposed routing model aims to enhance the timely delivery of Real-Time Data (RTD) with low latency, provide optimal resources for Non-Real Time (NRT) data delivery, optimize resource allocation, minimize delay, reduce energy consumption, and lower buffer and holding costs. These comprehensive parameters empower mobile-WSNs to fulfill the requirements of a Quality of Service (QoS)-oriented and energy-efficient V2V communication system.

Ibero-american International University > Research > Articles and Books Cerrado Inglés An extensive examination reveals that Wireless Sensor Networks (WSNs) offer a promising solution for essential sensing and event-driven data communication needs. WSNs hold significant potential for event-driven communication, primarily owing to their decentralized and infrastructure-free operational characteristics. However, the traditional WSN’s inherent static nature imposes limitations on its applicability, particularly in scenarios requiring generic operating characteristics or routing protocols for Vehicle-to-Vehicle (V2V) communication. This constraint arises from the immobility of sensor nodes within the network. Nonetheless, adopting a forward-looking perspective that incorporates mobility into WSNs opens up opportunities to create a mobile-WSN solution tailored for V2V communication.

Las pérdidas en tiempos de viaje y calidad de vida, ocasionadas por la congestión en las ciudades de hoy, prioriza la construcción de infraestructura vial enfatizada en la red vial para el auto, que aumenta el daño social y ambiental, que no se abordan con la rigurosidad matemática que deberían. En ese sentido, la forma de evaluar el mejor escenario de inversión en proyectos de infraestructura de transporte urbano y/o de sistemas inteligentes relacionados, tanto antes de (ex ante), como después de la puesta en marcha (ex post), es la planificación basada en medidas de desempeño operacional y aplicarlas en un proceso de evaluación de alternativas, como apoyo para la toma de decisiones y el monitoreo continuo. Este es el objetivo de la investigación y la propuesta, sobre la base de los análisis de la situación actual, de la red vial limeña, como caso de análisis. La metodología empleada para el desarrollo del trabajo, incluye los estados del arte y de la práctica más actual en el campo de la Ingeniería de tránsito urbano; y por lo tanto, pretende traer a la realidad de las ciudades latinoamericanas, los procedimientos establecidos en las ciudades de países desarrollados y adaptarlos de la mejor manera posible. El resultado será proponer un modelo procedimental basado en cálculos determinísticos y estocásticos, para resolver la problemática del derroche del dinero público en la construcción de proyectos de transporte y tránsito urbano, que no producen los beneficios de sistemas efectivos, económicamente rentables y equitativo para los residentes. Este modelo de evaluación del desempeño operacional es, sin duda, una buena herramienta y un punto de referencia prospectivo para medir la sostenibilidad en relación con el desarrollo urbano.

En la actualidad, se requiere que la información sea representada visualmente de forma adecuada, que permita a las empresas una correcta interpretación y permita una toma de decisiones eficaz. La visualización de datos juega un papel importante en las empresas y las Instituciones de Educación Superior (IES) no son la excepción, la visualización de datos permite convertir los datos en imágenes y darle un contexto a la información, para poder ser entendida y tomar decisiones acertadas en corto tiempo, para conseguir esto se debe utilizar distintas técnicas y modelos de visualización que permitan una representación gráfica adecuada, que sea fácil de interpretar. La mayoría de técnicas y modelos de visualización de datos identificados en la revisión de literatura debe adaptarse al tipo de información que se va a representar y en muchas ocasiones es complicado encontrar el modelo ideal y más aún si se trata de datos académicos generados por las IES. En este contexto, este trabajo propone el desarrollo de un modelo de visualización de datos que permita mejorar la representación visual de datos en la gestión académica, como caso de estudio en la Universidad Tecnológica Israel (UISRAEL) en Ecuador, el modelo propuesto debe adaptarse a la información académica generada por esta IES, para el desarrollo de este trabajo se utilizará un enfoque metodológico mixto con datos cualitativos y cuantitativos, una vez que el modelo este completamente fundamentado y diseñado, se pretende que el modelo sea aceptado utilizando el juicio de expertos en el área, de esta manera se pretende validar el estudio propuesto.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The IoT (Internet of Things) has played a promising role in e-healthcare applications during the last decade. Medical sensors record a variety of data and transmit them over the IoT network to facilitate remote patient monitoring. When a patient visits a hospital he may need to connect or disconnect medical devices from the medical healthcare system frequently. Also, multiple entities (e.g., doctors, medical staff, etc.) need access to patient data and require distinct sets of patient data. As a result of the dynamic nature of medical devices, medical users require frequent access to data, which raises complex security concerns. Granting access to a whole set of data creates privacy issues. Also, each of these medical user need to grant access rights to a specific set of medical data, which is quite a tedious task. In order to provide role-based access to medical users, this study proposes a blockchain-based framework for authenticating multiple entities based on the trust domain to reduce the administrative burden. This study is further validated by simulation on the infura blockchain using solidity and Python. The results demonstrate that role-based authorization and multi-entities authentication have been implemented and the owner of medical data can control access rights at any time and grant medical users easy access to a set of data in a healthcare system. The system has minimal latency compared to existing blockchain systems that lack multi-entity authentication and role-based authorization.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Pneumonia is a potentially life-threatening infectious disease that is typically diagnosed through physical examinations and diagnostic imaging techniques such as chest X-rays, ultrasounds or lung biopsies. Accurate diagnosis is crucial as wrong diagnosis, inadequate treatment or lack of treatment can cause serious consequences for patients and may become fatal. The advancements in deep learning have significantly contributed to aiding medical experts in diagnosing pneumonia by assisting in their decision-making process. By leveraging deep learning models, healthcare professionals can enhance diagnostic accuracy and make informed treatment decisions for patients suspected of having pneumonia. In this study, six deep learning models including CNN, InceptionResNetV2, Xception, VGG16, ResNet50 and EfficientNetV2L are implemented and evaluated. The study also incorporates the Adam optimizer, which effectively adjusts the epoch for all the models. The models are trained on a dataset of 5856 chest X-ray images and show 87.78%, 88.94%, 90.7%, 91.66%, 87.98% and 94.02% accuracy for CNN, InceptionResNetV2, Xception, VGG16, ResNet50 and EfficientNetV2L, respectively. Notably, EfficientNetV2L demonstrates the highest accuracy and proves its robustness for pneumonia detection. These findings highlight the potential of deep learning models in accurately detecting and predicting pneumonia based on chest X-ray images, providing valuable support in clinical decision-making and improving patient treatment.

University of La Romana > Research > Scientific Production Abierto Inglés Leukemia is a type of blood cell cancer that is in the bone marrow’s blood-forming cells. Two types of Leukemia are acute and chronic; acute enhances fast and chronic growth gradually which are further classified into lymphocytic and myeloid leukemias. This work evaluates a unique deep convolutional neural network (CNN) classifier that improves identification precision by carefully examining concatenated peptide patterns. The study uses leukemia protein expression for experiments supporting two different techniques including independence and applied cross-validation. In addition to CNN, multilayer perceptron (MLP), gated recurrent unit (GRU), and recurrent neural network (RNN) are applied. The experimental results show that the CNN model surpasses competitors with its outstanding predictability in independent and cross-validation testing applied on different features extracted from protein expressions such as amino acid composition (AAC) with a group of AAC (GAAC), tripeptide composition (TPC) with a group of TPC (GTPC), and dipeptide composition (DPC) for calculating its accuracies with their receiver operating characteristic (ROC) curve. In independence testing, a feature expression of AAC and a group of GAAC are applied using MLP and CNN modules, and ROC curves are achieved with overall 100% accuracy for the detection of protein patterns. In cross-validation testing, a feature expression on a group of AAC and GAAC patterns achieved 98.33% accuracy which is the highest for the CNN module. Furthermore, ROC curves show a 0.965% extraordinary result for the GRU module. The findings show that the CNN model is excellent at figuring out leukemia illnesses from protein expressions with higher accuracy.

Subjects > Teaching Ibero-american International University > Research > Doctoral Thesis Cerrado Español Se presenta la tesis doctoral orientada al uso, manejo y conservación del ecosistema subterráneo Hoyo del Aire, localizado en la región cárstica del municipio de La Paz, en el departamento de Santander – Colombia. Este ambiente hipogeo cuenta con dos sectores: el hoyo propiamente dicho con una profundidad superior a 260 m y una formación boscosa en el fondo, y una caverna interna con fauna y formaciones espeleológicas. El estudio involucró la recopilación de información literaria especializada, aplicación de técnicas de descenso–ascenso en alturas para el ingreso al fondo del Hoyo del Aire, conocimiento de la flora, fauna y espeleotemas más representativos, descripción cualitativa de los recursos naturales, así como valoración del potencial ecoturístico de la zona. La cobertura vegetal del fondo del hoyo contiene grupos de plantas muy diversas y propias de ambientes cálidos. A nivel de fauna se reportaron especies de aves, insectos y artrópodos nativos de Colombia.

The area of optical color picture encryption has recently emerged as one of the most talked-about subjects in the pitch of data security. Although it has been suggested that certain techniques used to encrypt color images, the majority of these techniques have traditionally been based on symmetric cryptographic modules. This paper present an alternate method for encrypting color images, which involves the utilization of an optical asymmetric cryptosystem. In this approach, we make use of a random modulus decomposition strategy in the gyrator domain, in addition to multiple wavelength and indexed picture methods. This allows to achieve optimal results. In order to establish fundamental characteristics for encryption keys, such as gyrator domain and decomposition masks P1 and P2. These fundamental parameters include, but are not limited to, random phase codes that are utilized by the optical cryptosystem. In addition, we have used this tool concurrently for the purposes of picture compression and encryption in order to achieve our goals. A performance analysis of the system has also been carried out, during which its sensitivity to a number of encryption factors, such as gyrator transform order and robustness, was evaluated. In addition, we have investigated the safety of the optical asymmetric cryptosystem while it is being used to decrypt information. In conclusion, we give numerical findings that verify the viability and efficiency of the optical cryptosystem for the encryption of color images.

El presente trabajo presenta una propuesta de modelo de redensificación para áreas urbanas, con el objetivo de mejorar la calidad de vida de los residentes urbanos. La premisa fundamental es la optimización del uso de la infraestructura preexistente en el desarrollo residencial y otros servicios. Como caso de estudio, se examinará la zona conurbada de Zacatecas-Guadalupe, dos municipios pertenecientes al estado de Zacatecas, México. Se analizarán las ventajas, desventajas y el análisis de costos y beneficios de diversas alternativas de redensificación, ya sea a través de viviendas unifamiliares, que han predominado en la zona desde su fundación, o mediante la introducción de viviendas multifamiliares en edificios verticales. Esta propuesta busca elevar los estándares de vida al ofrecer nuevas viviendas en zonas urbanas consolidadas y en desarrollo, que estén equipadas con servicios esenciales, como abastecimiento, educación, cultura, deporte, recreación, agua potable y energía eléctrica, entre otros. El objetivo es mejorar la movilidad de los residentes mediante un transporte público eficiente y accesible, permitiendo la realización de actividades sin requerir una inversión significativa de recursos económicos o tiempo. El enfoque de la investigación se basará en una revisión exhaustiva de documentos y un estudio de campo que refleje la situación actual de la zona conurbada de Zacatecas-Guadalupe. Esto permitirá establecer estrategias de redensificación y definir un área de acción específica, eligiendo zonas con una alta concentración de equipamiento urbano y conectadas a los principales ejes de transporte público. Además, se analizarán programas, documentos legales y contribuciones de entidades gubernamentales involucradas en el tema.

Estudios preliminares del sistema metrológico actual de Ghana revelan la necesidad de generar un nuevo sistema. El sistema presenta deficiencias fundamentales, ya que no cumple con especificaciones normativas, legales, técnicas y requerimientos administrativos, de infraestructura, instalaciones y capacitación. Por ejemplo, la administración de metrología está a cargo de la Autoridad de Normalización, cuyo principal mandato es la formulación de normas. Aunque el vigente decreto de pesas y medidas de 1975 declara como obligatorio el uso de unidades de medida inglesas, actualmente se realizan mediciones en el sistema internacional. Además, no existe un laboratorio metrológico nacional ni personal calificado para asegurar la trazabilidad de las actividades metrológicas al sistema internacional. Estas deficiencias afectan los sectores sociales y comerciales, ya que los mercados y acuerdos internacionales actuales requieren que los productos y servicios cumplan con normativas de calidad. Un sistema metrológico nacional que cumpla con criterios internacionales protege calidad de vida, garantiza equidad en comercio y promueve competitividad industrial. Lograr esto implica realizar mediciones, puesto que "solo se puede valorar lo que se mide, y solo se puede mejorar lo que se puede valorar". Esto genera confianza en productos o servicios tanto para los productores como para los consumidores. En este contexto, esta investigación propone el rediseño del sistema metrológico ghanés para que cumpla con criterios internacionales y aborde los sectores socioeconómicos, garantizando la calidad, Innovación y competitividad. Para ello, se analizó la infraestructura y las instalaciones existentes, la adecuación al marco legislativo, los organismos certificadores, los laboratorios de calibración y sus acreditaciones de acuerdo con los criterios internacionales. Las herramientas utilizadas en el estudio incluyeron la recopilación, el análisis y la síntesis de información existente, observaciones, encuestas y entrevistas con los actores relevantes en la infraestructura de calidad y las autoridades reguladoras.

University of La Romana > Research > Scientific Production Abierto Inglés With the rapid increase of users over social media, cyberbullying, and hate speech problems have arisen over the past years. Automatic hate speech detection (HSD) from text is an emerging research problem in natural language processing (NLP). Researchers developed various approaches to solve the automatic hate speech detection problem using different corpora in various languages, however, research on the Urdu language is rather scarce. This study aims to address the HSD task on Twitter using Roman Urdu text. The contribution of this research is the development of a hybrid model for Roman Urdu HSD, which has not been previously explored. The novel hybrid model integrates deep learning (DL) and transformer models for automatic feature extraction, combined with machine learning algorithms (MLAs) for classification. To further enhance model performance, we employ several hyperparameter optimization (HPO) techniques, including Grid Search (GS), Randomized Search (RS), and Bayesian Optimization with Gaussian Processes (BOGP). Evaluation is carried out on two publicly available benchmarks Roman Urdu corpora comprising HS-RU-20 corpus and RUHSOLD hate speech corpus. Results demonstrate that the Multilingual BERT (MBERT) feature learner, paired with a Support Vector Machine (SVM) classifier and optimized using RS, achieves state-of-the-art performance. On the HS-RU-20 corpus, this model attained an accuracy of 0.93 and an F1 score of 0.95 for the Neutral-Hostile classification task, and an accuracy of 0.89 with an F1 score of 0.88 for the Hate Speech-Offensive task. On the RUHSOLD corpus, the same model achieved an accuracy of 0.95 and an F1 score of 0.94 for the Coarse-grained task, alongside an accuracy of 0.87 and an F1 score of 0.84 for the Fine-grained task.

Soft stories are a common reason for building collapses during severe earthquakes. This paper investigates a solution for seismic rehabilitation with hysteretic dampers for a building in Spain affected by the Lorca earthquake in 2011. The building had reinforced concrete frames, stronger beams than columns, a soft first story, and masonry walls. The dimensions of hysteretic dampers are presented in terms of their mechanical properties as stiffness, strength, and yield deformation. The energy-based method provides the stiffness, strength, and energy dissipation capacity required by hysteretic dampers to get the entire structure to endure the design earthquake without exceeding the maximum imposed drift on the first story. The seismic performance of the upgraded structure is evaluated by nonlinear dynamic analyses, considering the energy that contributes to structural damage expressed in terms of equivalent velocity based on the Seismic Standard NCSE-02, the accelerograms of the Lorca earthquake, and 23 historic earthquakes scaled to the energy input. In conclusion, the solution improves seismic performance. Hysteretic dampers increase the stiffness of the soft story and take it to similar levels to the upper stories. The modes of vibration are translational, the drift of the first story decreases by 50%, and drifts of the upper stories are kept low. The damage is concentrated on the hysteretic dampers instead of the main structure, and plastic joints are concentrated on the base of the first-story columns, which is an acceptable mechanism to dissipate energy to avoid the main structure collapse.

It has previously been shown that epilithic bacterial biopolymers used as coatings influenced the physical properties (surface hardness and color change) at different levels and decreased the surface disaggregation of experimental limestone when evaluated at the laboratory level. A short-term study (30 days) was conducted to evaluate the performance under natural conditions of limestone blocks exposed to tropical conditions of a selected bacterial biopolymer (TM1B-488, after the producing bacterium) and a previously unreported Mayan plant biopolymer known as “Escobilla”, Sida rhombifolia (Malvaceae) used in conservation procedures. Surface hardness (Leeb units) and color (L*a*b* coordinates) were measured and statistically tested for two types of limestone blocks (sound and deteriorated limestone). Both biopolymers increased surface hardness, decreased surface disaggregation, and did not alter color. Escobilla polymer is a carbohydrate-rich biopolymer characterized by tangential filtration, global chemical composition, and monosaccharide composition of hydrolyzed polymer. These results indicate that biopolymers of a heteropolysaccharide nature are constituted by some anionic charge residues that could contribute to surface stabilization and consolidation, but compatibility with traditional building materials (mortars) and longer time of exposure (a year) are necessary to fully assess their applicability in the restoration of architectural heritage.

University of La Romana > Research > Scientific Production Abierto Inglés Telephysiotherapy has emerged as a vital solution for delivering remote healthcare, particularly in response to global challenges such as the COVID-19 pandemic. This study seeks to enhance telephysiotherapy by developing a system capable of accurately classifying physiotherapeutic exercises using PoseNet, a state-of-the-art pose estimation model. A dataset was collected from 49 participants (35 males, 14 females) performing seven distinct exercises, with twelve anatomical landmarks then extracted using the Google MediaPipe library. Each landmark was represented by four features, which were used for classification. The core challenge addressed in this research involves ensuring accurate and real-time exercise classification across diverse body morphologies and exercise types. Several tree-based classifiers, including Random Forest, Extra Tree Classifier, XGBoost, LightGBM, and Hist Gradient Boosting, were employed. Furthermore, two novel ensemble models called RandomLightHist Fusion and StackedXLightRF are proposed to enhance classification accuracy. The RandomLightHist Fusion model achieved superior accuracy of 99.6%, demonstrating the system’s robustness and effectiveness. This innovation offers a practical solution for providing real-time feedback in telephysiotherapy, with potential to improve patient outcomes through accurate monitoring and assessment of exercise performance.

University of La Romana > Research > Scientific Production Abierto Inglés Plant stress reduction research has advanced significantly with the use of Artificial Intelligence (AI) techniques, such as machine learning and deep learning. This is a significant step toward sustainable agriculture. Innovative insights into the physiological responses of plants mostly crops to drought stress have been revealed through the use of complex algorithms like gradient boosting, support vector machines (SVM), recurrent neural network (RNN), and long short-term memory (LSTM), combined with a thorough examination of the TYRKC and RBR-E3 domains in stress-associated signaling proteins across a range of crop species. Modern resources were used in this study, including the UniProt protein database for crop physiochemical properties associated with specific signaling domains and the SMART database for signaling protein domains. These insights were then applied to deep learning and machine learning techniques after careful data processing. The rigorous metric evaluations and ablation analysis that typified the study’s approach highlighted the algorithms’ effectiveness and dependability in recognizing and classifying stress events. Notably, the accuracy of SVM was 82%, while gradient boosting and RNN showed 96%, and 94%, respectively and LSTM obtained an astounding 97% accuracy. The study observed these successes but also highlights the ongoing obstacles to AI adoption in agriculture, emphasizing the need for creative thinking and interdisciplinary cooperation. In addition to its scholarly value, the collected data has significant implications for improving resource efficiency, directing precision agricultural methods, and supporting global food security programs. Notably, the gradient boosting and LSTM algorithm outperformed the others with an exceptional accuracy of 96% and 97%, demonstrating their potential for accurate stress categorization.

Chemical modification of guar gum was done by graft copolymerization of monomer hydroxyethyl methacrylate (HEMA) using azobisisobutyronitrile (AIBN) as initiator. Optimal reaction parameters were settled by varying one reaction condition and keeping the other constant. The optimum reaction conditions worked out were solvent system: binary, [H2O] = 15.00 mL, [acetone] = 5.00 mL, [HEMA] = 82.217× 10−2 mol/L, [AIBN] = 3.333 × 10−2 mol/L, reaction time = 3 h, reaction temperature = 60 °C on to 1.00 g guar gum with Pg = 1694.6 and %GE = 68,704.152. Pure guar gum polymer and grafts were analyzed by several physicochemical investigation techniques like FTIR, SEM, XRD, EDX, and swelling studies. Percent swelling of the guar gum polymer and grafts was investigated at pH 2.2, 7.0, 7.4 and 9.4 concerning time. The finest yield of Ps was recorded at pH 9.4 with time 24 h for graft copolymer. Guar gum and grafted samples were explored for the sorption of toxic dye Bismarck brown Y from the aqueous solution with respect to variable contact time, pH, temperature and dye concentration so as to investigate the stimuli responsive sorption behaviour. Graft copolymers showed better results than guar gum with percent dye uptake (Du) of 97.588 % in 24 h contact time, 35 °C temperature, 9.4 pH at 150.00 ppm dye feed concentration as compared to Guar gum which only showed 85.260 % dye uptake at alike dye fed concentration. The kinetic behaviour of the polymeric samples was evaluated by applying many adsorption isotherms and kinetic models. The value of 1/n was between 0 → 1 showing that there was physisorption of the BB dye that took place on the surface of the polymers. Thermodynamics of BB Y adsorption onto hydrogels was investigated concerning the Van't Hoff equation. -∆G° values obtained from the curve proved the spontanity of the process. Within the context of adsorption efficiency, an investigation was conducted to examine the process of sorption of Bismarck brown Y dye from aqueous solutions. The graft copolymers demonstrated remarkable adsorption abilities, achieving a dye uptake (Du) of 97.588 % over a 24-h period at a temperature of 35 °C, pH level of 9.4, and a dye concentration of 150.00 ppm. The raised adsorption capacity was additionally corroborated by the application of several adsorption isotherms and kinetic models, which indicated that physisorption is the prevailing process/mechanism. Additionally, the thermodynamic research, utilising the Van't Hoff equation, validated the spontaneity of the adsorption phenomenon, as evidenced by the presence of a negative ∆G° values. The thermodynamic analysis revealed herein establishes a strong scientific foundation for the effectiveness of adsorbent composed of graft copolymers based on guar gum. The research conclude the efficiency of the guar gum based grafted copolymers for the water remediation as efficient adsorbents. The captured dye can be re-utilised and the hydrogels can be used for the same purpose in number of cycles.

University of La Romana > Research > Scientific Production Abierto Inglés Driving while drowsy poses significant risks, including reduced cognitive function and the potential for accidents, which can lead to severe consequences such as trauma, economic losses, injuries, or death. The use of artificial intelligence can enable effective detection of driver drowsiness, helping to prevent accidents and enhance driver performance. This research aims to address the crucial need for real-time and accurate drowsiness detection to mitigate the impact of fatigue-related accidents. Leveraging ultra-wideband radar data collected over five minutes, the dataset was segmented into one-minute chunks and transformed into grayscale images. Spatial features are retrieved from the images using a two-dimensional Convolutional Neural Network. Following that, these features were used to train and test multiple machine learning classifiers. The ensemble classifier RF-XGB-SVM, which combines Random Forest, XGBoost, and Support Vector Machine using a hard voting criterion, performed admirably with an accuracy of 96.6%. Additionally, the proposed approach was validated with a robust k-fold score of 97% and a standard deviation of 0.018, demonstrating significant results. The dataset is augmented using Generative Adversarial Networks, resulting in improved accuracies for all models. Among them, the RF-XGB-SVM model outperformed the rest with an accuracy score of 99.58%.

University of La Romana > Research > Scientific Production Abierto Inglés This paper studies the latest and state-of-the-art underwater thermal energy harvesting algorithms and techniques designed in the latest decade (2014-2024). The techniques are classified based on their unique operations for energy harvesting. This classification includes thermal energy harvesting using a phase change material (PCM), thermoelectric generator (TEG) and multi-source harvesting. Every class of techniques is described by its operation using a schematic diagram and a mathematical model to fully understand its working principle. Moreover, every individual technique is also described in terms of its operation, amount of harvested energy/power and the aspect(s) where margin of further improvement exists. Also, a comparative analysis of the classified algorithms is performed with each other as well as with other underwater energy harvesting techniques (solar, piezoelectric, wave) to highlight their effectiveness and feasibility in a diverse set of underwater and various other applications. The classified techniques are also compared in terms of harvested output to indicate their harvesting efficiency. Furthermore, the publications made in the latest decade in terms of thermal energy harvesting using PCM, TEG and multi-source methods are also graphically depicted. Such a description of the studied techniques and classified methods is unique from the already existing underwater energy harvesting reviews in literature where an in-depth and thorough analysis is absent, rather only marginal description is given. The harvesting results indicate that hybrid (multi-source) and PCM methods have the greatest amount of harvested power and energy, respectively. Finally, the research challenges in underwater thermal energy harvesting are specified and areas of further research are highlighted for future investigation.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Named Entity Recognition (NER) is a natural language processing task that has been widely explored for different languages in the recent decade but is still an under-researched area for the Urdu language due to its rich morphology and language complexities. Existing state-of-the-art studies on Urdu NER use various deep-learning approaches through automatic feature selection using word embeddings. This paper presents a deep learning approach for Urdu NER that harnesses FastText and Floret word embeddings to capture the contextual information of words by considering the surrounding context of words for improved feature extraction. The pre-trained FastText and Floret word embeddings are publicly available for Urdu language which are utilized to generate feature vectors of four benchmark Urdu language datasets. These features are then used as input to train various combinations of Long Short-Term Memory (LSTM), Bidirectional LSTM (BiLSTM), Gated Recurrent Unit (GRU), CRF, and deep learning models. The results show that our proposed approach significantly outperforms existing state-of-the-art studies on Urdu NER, achieving an F-score of up to 0.98 when using BiLSTM+GRU with Floret embeddings. Error analysis shows a low classification error rate ranging from 1.24% to 3.63% across various datasets showing the robustness of the proposed approach. The performance comparison shows that the proposed approach significantly outperforms similar existing studies.

University of La Romana > Research > Scientific Production Abierto Inglés Accurately predicting the remaining useful life (RUL) of lithium-ion (Li-ion) batteries is vital for improving battery performance and safety in applications such as consumer electronics and electric vehicles. While the prediction of RUL for these batteries is a well-established field, the current research refines RUL prediction methodologies by leveraging deep learning techniques, advancing prediction accuracy. This study proposes AccuCell Prodigy, a deep learning model that integrates auto-encoders and long short-term memory (LSTM) layers to enhance RUL prediction accuracy and efficiency. The model’s name reflects its precision (“AccuCell”) and predictive strength (“Prodigy”). The proposed methodology involves preparing a dataset of battery operational features, split using an 80–20 ratio for training and testing. Leveraging 22 variations of current (critical parameter) across three Li-ion cells, AccuCell Prodigy significantly reduces prediction errors, achieving a mean square error of 0.1305%, mean absolute error of 2.484%, and root mean square error of 3.613%, with a high R-squared value of 0.9849.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The essence of quantum machine learning is to optimize problem-solving by executing machine learning algorithms on quantum computers and exploiting potent laws such as superposition and entanglement. Support vector machine (SVM) is widely recognized as one of the most effective classification machine learning techniques currently available. Since, in conventional systems, the SVM kernel technique tends to sluggish down and even fail as datasets become increasingly complex or jumbled. To compare the execution time and accuracy of conventional SVM classification to that of quantum SVM classification, the appropriate quantum features for mapping need to be selected. As the dataset grows complex, the importance of selecting an appropriate feature map that outperforms or performs as well as the classification grows. This paper utilizes conventional SVM to select an optimal feature map and benchmark dataset for predicting air quality. Experimental evidence demonstrates that the precision of quantum SVM surpasses that of classical SVM for air quality assessment. Using quantum labs from IBM’s quantum computer cloud, conventional and quantum computing have been compared. When applied to the same dataset, the conventional SVM achieved an accuracy of 91% and 87% respectively, whereas the quantum SVM demonstrated an accuracy of 97% and 94% respectively for air quality prediction. The study introduces the use of quantum Support Vector Machines (SVM) for predicting air quality. It emphasizes the novel method of choosing the best quantum feature maps. Through the utilization of quantum-enhanced feature mapping, our objective is to exceed the constraints of classical SVM and achieve unparalleled levels of precision and effectiveness. We conduct precise experiments utilizing IBM’s state-of-the-art quantum computer cloud to compare the performance of conventional and quantum SVM algorithms on a shared dataset.

It aims to enhance signal quality by adjusting the characteristics of the received signal. Particle swarm optimization (PSO) algorithms have shown promise in optimizing the tap weights of the equalizer.

For the sentiment analysis, a deep transformer-based Bidirectional Encoder Representations from Transformers (BERT) model with three dense layers of neural networks is proposed. Additionally, machine and deep learning models with fine-tuned parameters are utilized for a comparative analysis. Experimental results demonstrate the superior performance of the proposed BERT model, achieving an accuracy of 96.49%.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Chronic obstructive pulmonary disease (COPD) is a severe and chronic ailment that is currently ranked as the third most common cause of mortality across the globe. COPD patients often experience debilitating symptoms such as chronic coughing, shortness of breath, and fatigue. Sadly, the disease frequently goes undiagnosed until it is too late, leaving patients without the care they desperately need. So, COPD detection at an early stage is crucial to prevent further damage to the lungs and improve quality of life. Traditional COPD detection methods often rely on physical examinations and tests such as spirometry, chest radiography, blood gas tests, and genetic tests. However, these methods may not always be accurate or accessible. One of the key vital signs for detecting COPD is the patient’s respiration rate. However, it is crucial to consider a patient’s medical and demographic characteristics simultaneously for better detection results. To address this issue, this study aims to detect COPD patients using artificial intelligence techniques. To achieve this goal, a novel framework is proposed that utilizes ultra-wideband (UWB) radar-based temporal and spectral features to build machine learning and deep learning models. This new set of temporal and spectral features is extracted from respiration data collected non-invasively from 1.5 m distance using UWB radar. Different machine learning and deep learning models are trained and tested on the collected dataset. The findings are promising, with a high accuracy score of 100% for COPD detection. This means that the proposed framework could potentially save lives by identifying COPD patients at an early stage. The k-fold cross-validation technique and performance comparison with the state-of-the-art studies are applied to validate its performance, ensuring that the results are robust and reliable. The high accuracy score achieved in the study implies that the proposed framework has the potential for the efficient detection of COPD at an early stage.

University of La Romana > Research > Scientific Production Abierto Inglés Behavioral economics and artificial intelligence (AI) have been two rapidly growing fields of research over the past few years. While behavioral economics aims to combine concepts from psychology, sociology, and neuroscience with classical economic thoughts to understand human decision-making processes in the complex economic environment, AI on the other hand, focuses on creating intelligent machines that can mimic human cognitive abilities such as learning, problem-solving, decision-making, and language understanding. The intersection of these two fields has led to thrilling research theories and practical applications. This study provides a bibliometric analysis of the literature on AI and behavioral economics to gain insight into research trends in this field. We conducted this bibliometric analysis using the Web of Science database on articles published between 2012 and 2022 that were related to AI and behavioral economics. VOSviewer and Bibliometrix R package were utilized to identify influential authors, journals, institutions, and countries in the field. Network analysis was also performed to identify the main research themes and their interrelationships. The analysis revealed that the number of publications on AI and behavioral economics has been increasing steadily over the past decade. We found that most studies focused on customer and consumer behavior, including topics such as decision-making under uncertainty, neuroeconomics, and behavioral game theory, combined mainly with machine learning and deep learning techniques. We also identified several emerging themes, including the use of AI in nudging and prospect theory in behavioral finance, as well as undeveloped themes such as AI-driven behavioral macroeconomics. The findings suggests that there is a need for more interdisciplinary collaboration between researchers in behavioral economics and AI. We also suggest that future research on AI and behavioral economics further consider the ethical implications of using AI and behavioral insights in decision-making. This study can serve as a valuable resource for researchers interested in AI and behavioral economics.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The precise prediction of power estimates of wind–solar renewable energy sources becomes challenging due to their intermittent nature and difference in intensity between day and night. Machine-learning algorithms are non-linear mapping functions to approximate any given function from known input–output pairs and can be used for this purpose. This paper presents an artificial neural network (ANN)-based method to predict hybrid wind–solar resources and estimate power generation by correlating wind speed and solar radiation for real-time data. The proposed ANN allows optimization of the hybrid system’s operation by efficient wind and solar energy production estimation for a given set of weather conditions. The proposed model uses temperature, humidity, air pressure, solar radiation, optimum angle, and target values of known wind speeds, solar radiation, and optimum angle. A normalization function to narrow the error distribution and an iterative method with the Levenberg–Marquardt training function is used to reduce error. The experimental results show the effectiveness of the proposed approach against the existing wind, solar, or wind–solar estimation methods. It is envisaged that such an intelligent yet simplified method for predicting wind speed, solar radiation, and optimum angle, and designing wind–solar hybrid systems can improve the accuracy and efficiency of renewable energy generation.

Companies must refine and develop methods to simplify and optimize the procurement process in a highly competitive environment. This paper presents a methodology to help managers of project-based organizations analyze procurement processes to determine the optimal framework for simultaneously addressing multiple objectives. These goals include minimizing the time between the generation and required approval for a purchase, identifying unnamed activities, and allocating the budget efficiently. In this paper, we apply process mining algorithms to a dataset consisting of event logs on Oracle Financials-based enterprise resource planning (ERP) procurement processes in ERP systems and demonstrate interesting results leading to project procurement intelligence (PPI). The provided log data is the real-life data consisting of 180,462 events referring to seven activities within 43,101 cases. The logged procurement processes are filtered and analyzed using the open-source process mining frameworks PrOM and Disco. As a result of the process mining activities, a simulation of the discovered process model derived from the event log of the entire procurement process is presented, and the most frequent potential behaviors are identified. This analysis and extraction of frequent processes from corporate event logs help organizations understand, adapt, and redesign procurement operations and, most importantly, make them more efficient and of higher quality. This study shows that after the successful formulation of guiding principles, data refinement, and process structure optimization, the case study results are considered significant by the organization’s management.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Internet of Things (IoT) has made significant strides in energy management systems recently. Due to the continually increasing cost of energy, supply–demand disparities, and rising carbon footprints, the need for smart homes for monitoring, managing, and conserving energy has increased. In IoT-based systems, device data are delivered to the network edge before being stored in the fog or cloud for further transactions. This raises worries about the data’s security, privacy, and veracity. It is vital to monitor who accesses and updates this information to protect IoT end-users linked to IoT devices. Smart meters are installed in smart homes and are susceptible to numerous cyber attacks. Access to IoT devices and related data must be secured to prevent misuse and protect IoT users’ privacy. The purpose of this research was to design a blockchain-based edge computing method for securing the smart home system, in conjunction with machine learning techniques, in order to construct a secure smart home system with energy usage prediction and user profiling. The research proposes a blockchain-based smart home system that can continuously monitor IoT-enabled smart home appliances such as smart microwaves, dishwashers, furnaces, and refrigerators, among others. An approach based on machine learning was utilized to train the auto-regressive integrated moving average (ARIMA) model for energy usage prediction, which is provided in the user’s wallet, to estimate energy consumption and maintain user profiles. The model was tested using the moving average statistical model, the ARIMA model, and the deep-learning-based long short-term memory (LSTM) model on a dataset of smart-home-based energy usage under changing weather conditions. The findings of the analysis reveal that the LSTM model accurately forecasts the energy usage of smart homes.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Artificial intelligence has made substantial progress in medicine. Automated dental imaging interpretation is one of the most prolific areas of research using AI. X-ray and infrared imaging systems have enabled dental clinicians to identify dental diseases since the 1950s. However, the manual process of dental disease assessment is tedious and error-prone when diagnosed by inexperienced dentists. Thus, researchers have employed different advanced computer vision techniques, and machine- and deep-learning models for dental disease diagnoses using X-ray and near-infrared imagery. Despite the notable development of AI in dentistry, certain factors affect the performance of the proposed approaches, including limited data availability, imbalanced classes, and lack of transparency and interpretability. Hence, it is of utmost importance for the research community to formulate suitable approaches, considering the existing challenges and leveraging findings from the existing studies. Based on an extensive literature review, this survey provides a brief overview of X-ray and near-infrared imaging systems. Additionally, a comprehensive insight into challenges faced by researchers in the dental domain has been brought forth in this survey. The article further offers an amalgamative assessment of both performances and methods evaluated on public benchmarks and concludes with ethical considerations and future research avenues.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés In the field of natural language processing, machine translation is a colossally developing research area that helps humans communicate more effectively by bridging the linguistic gap. In machine translation, normalization and morphological analyses are the first and perhaps the most important modules for information retrieval (IR). To build a morphological analyzer, or to complete the normalization process, it is important to extract the correct root out of different words. Stemming and lemmatization are techniques commonly used to find the correct root words in a language. However, a few studies on IR systems for the Urdu language have shown that lemmatization is more effective than stemming due to infixes found in Urdu words. This paper presents a lemmatization algorithm based on recurrent neural network models for the Urdu language. However, lemmatization techniques for resource-scarce languages such as Urdu are not very common. The proposed model is trained and tested on two datasets, namely, the Urdu Monolingual Corpus (UMC) and the Universal Dependencies Corpus of Urdu (UDU). The datasets are lemmatized with the help of recurrent neural network models. The Word2Vec model and edit trees are used to generate semantic and syntactic embedding. Bidirectional long short-term memory (BiLSTM), bidirectional gated recurrent unit (BiGRU), bidirectional gated recurrent neural network (BiGRNN), and attention-free encoder–decoder (AFED) models are trained under defined hyperparameters. Experimental results show that the attention-free encoder-decoder model achieves an accuracy, precision, recall, and F-score of 0.96, 0.95, 0.95, and 0.95, respectively, and outperforms existing models Hafeez, Rabab and Anwar, Muhammad Waqas and Jamal, Muhammad Hasan and Fatima, Tayyaba and Martínez Espinosa, Julio César and Dzul López, Luis Alonso and Bautista Thompson, Ernesto and Ashraf, Imran UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, ulio.martinez@unini.edu.mx, luis.dzul@uneatlantico.es, ernesto.bautista@unini.edu.mx, UNSPECIFIED

Ibero-american International University > Research > Articles and Books Abierto Inglés This paper presents a current- and voltage-driven protection scheme for transmission lines based on a hybrid mix of Stockwell transform (ST) and Hilbert transform (HT). Use of both current and voltage waveforms to detect and categorize faults, improves the reliability of this protection scheme and avoids false tripping. Current and voltage waveforms captured during a period of fault are analyzed using ST to compute a median intermediate fault index (MIFI), a maximum value intermediate fault index (MVFI), and a summation intermediate fault index (SIFI). Current and voltage signals are analyzed via applying HT to compute a Hilbert fault index (HFI). The proposed hybrid current and voltage fault index (HCVFI) is obtained from the MIFI, MVFI, SIFI, and HFI. A threshold magnitude for this hybrid current and voltage fault index (HCVFITH) is set to 500 to identify the faulty phase. The HCVFIT is selected after testing the method for various conditions of different fault locations, different fault impedances, different fault occurrence angles, and reverse flows of power. Fault classification is performed using the number of faulty phases and an index for ground detection (IGD). The ground involved in a fault is detected by comparison of peak IGD magnitude with a threshold for ground detection (THGD). THGD is considered equal to 1000 in this study. The study is carried out using a two-terminal transmission line modeled in MATLAB software. The performance of the proposed technique is better compared to a discrete wavelet transform (DWT)-based technique, a time–frequency approach, and an alienation method. Our algorithm effectively detected an AG fault, observed on a practical transmission line.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Automated dental imaging interpretation is one of the most prolific areas of research using artificial intelligence. X-ray imaging systems have enabled dental clinicians to identify dental diseases. However, the manual process of dental disease assessment is tedious and error-prone when diagnosed by inexperienced dentists. Thus, researchers have employed different advanced computer vision techniques, as well as machine and deep learning models for dental disease diagnoses using X-ray imagery. In this regard, a lightweight Mask-RCNN model is proposed for periapical disease detection. The proposed model is constructed in two parts: a lightweight modified MobileNet-v2 backbone and region-based network (RPN) are proposed for periapical disease localization on a small dataset. To measure the effectiveness of the proposed model, the lightweight Mask-RCNN is evaluated on a custom annotated dataset comprising images of five different types of periapical lesions. The results reveal that the model can detect and localize periapical lesions with an overall accuracy of 94%, a mean average precision of 85%, and a mean insection over a union of 71.0%. The proposed model improves the detection, classification, and localization accuracy significantly using a smaller number of images compared to existing methods and outperforms state-of-the-art approaches Fatima, Anum and Shafi, Imran and Afzal, Hammad and Mahmood, Khawar and Díez, Isabel de la Torre and Lipari, Vivian and Brito Ballester, Julién and Ashraf, Imran UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, vivian.lipari@uneatlantico.es, julien.brito@uneatlantico.es, UNSPECIFIED

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Monitoring tool conditions and sub-assemblies before final integration is essential to reducing processing failures and improving production quality for manufacturing setups. This research study proposes a real-time deep learning-based framework for identifying faulty components due to malfunctioning at different manufacturing stages in the aerospace industry. It uses a convolutional neural network (CNN) to recognize and classify intermediate abnormal states in a single manufacturing process. The manufacturing process for aircraft factory products comprises different phases; analyzing the components after the integration is labor-intensive and time-consuming, which often puts the company’s stake at high risk. To overcome these challenges, the proposed AI-based system can perform inspection and defect detection and alleviate the probability of components’ needing to be re-manufacturing after being assembled. In addition, it analyses the impact value, i.e., rework delays and costs, of manufacturing processes using a statistical process control tool on real-time data for various manufactured components. Defects are detected and classified using the CNN and teachable machine in the single manufacturing process during the initial stage prior to assembling the components. The results show the significance of the proposed approach in improving operational cost management and reducing rework-induced delays. Ground tests are conducted to calculate the impact value followed by the air tests of the final assembled aircraft. The statistical results indicate a 52.88% and 34.32% reduction in time delays and total cost, respectively.

Desde a descoberta do fogo, impulsionador da energética baseada no uso da lenha, depois carvão, combustíveis fósseis, eletricidade, além da polêmica solução energética via fusão e fissão nuclear, a problemática energética esteve e estará sempre interferindo no sistema produtivo e movimentos sociais, mundialmente. Há preocupação quanto ao consumo, conservação e distribuição de energia elétrica, devido o aspecto evolutivo do ser humano, que busca preservar o meio ambiente, dominando novas técnicas para fazer uso dos recursos energéticos disponíveis na natureza sem impactar demais o ambiente de convívio. No mundo existem problemas de fornecimento de energia elétrica, não é diferente no Brasil. A evolução das novas tecnologias e o aproveitamento do sistema natural, o Sol, surge novo horizonte de possibilidade denominada como “geração de energia por sistema fotovoltaico”, que encontra no Brasil boas condições de implantação relacionadas às características climáticas. Esta pesquisa busca verificar e analisar a contribuição da aquisição de conjunto de painéis fotovoltaicos com a capacidade de geração de 1MWp proveniente do projeto de Eficiência Energético (PEE), avaliar o monitoramento, controle e desempenho da operação de sistema híbrido e a instalação de usina minirede com fonte de energia renováveis. O objetivo é identificar como a implantação de usina de minigeração de energia fotovoltaica em uma universidade federal, pode contribuir para a comunidade universitária referente à diminuição de custos e à preservação ambiental. Serão analisados resultados econômicos, no setor financeiro, e no consumo de energia no Campus Universitária da Universidade Federal do Paraná (UFPR). A metodologia utilizada foi descritivo-exploratória, qualitativa, realizado questionário aberto e entrevista semiestruturada. Concluiu-se que o sistema pode trazer benefícios a longo prazo, maior parte dos entrevistados considera o grande potencial do Brasil na expansão da exploração de outras fontes de energia, da hidroelétrica, que além de onerosa, traz menos vantagens relacionadas aos contextos ambiental e social.

El objetivo general de esta investigación es el diseño de una matriz como herramienta para la evaluación de requerimientos de calidad, medio ambiente y seguridad para una empresa automotriz ubicada en Reynosa Tamaulipas, México, abordando el problema que se genera debido al impacto en la organización por los incumplimientos en la falta de estandarización y evaluación de requerimientos de cliente y normativos. Esta investigación se presenta y desarrolla con el uso de los métodos lógicos de deducción, análisis y síntesis de mejora continua, la metodología de Ishikawa o diagrama pescado, la metodología de análisis de causa y efecto y de evaluación de riesgos. Analizados los cambios de las normas y sus requerimientos se observa que los principales hallazgos en las auditorias son con relación al cumplimento en la evaluación de requerimientos del cliente debido a que las implementaciones de los sistemas de gestión en las organizaciones se llevan a cabo en diferentes etapas y este desfase en la gestión de los proyectos complica la estandarización y genera la posibilidad de riesgos. La matriz como herramienta para la evaluación de requerimientos de calidad, medio ambiente y seguridad nos brinda la pauta para eficientizar la gestión de la organización, al eliminar la duplicidad de documentos, de controles no aplicables y entrenamientos repetitivos, también nos permite reducir al mínimo la carga de trabajo y esfuerzos que se genera debido al análisis de requerimientos de los sistemas como apartados aislados y no de forma global.

La integración de modelos de desarrollo sostenible muestra una visión compartida, holística y de largo plazo, donde se busca prosperidad y oportunidades económicas. Por su parte, la construcción sostenible representa un compromiso con el Medio Ambiente así́ como, una especial atención al impacto ambiental. La generación y demanda de energía renovable asociada en la operación de una PTAR permite combinar sistemas de captación de energía eléctrica mediante redes fotovoltaicas y la automatización mediante sistemas de lenguaje de programación PHP y administración de objetos javascript integrados en HTML perteneciente a la categoría de código abierto y, con la ventaja de ser gratuito. Para ello, se tomó una muestra 2000 pobladores de la zona de Chilón y se determinaron parámetros tales como ángulos de salida del sol, declinaciones, excentricidades, radiaciones difusas, directas, índices de claridad, radiaciones sobre planos inclinados y horizontales para obtener la irradiación global de la zona de chilón de 868.13Wh/m2/día. Conociendo la cantidad de radiación global sobre el plano inclinado que llega en la zona, se encontró que la hora solar pico (HSP), tuvo un valor de 5, mientras que la energía diaria captada por los 10 paneles solares con potencia de 340 W colocados en serie fue de 10,059.2 W al día; con una corriente de 797.0833 Amperes, considerando el uso de 2 baterías de 650 Amperes para la PTAR propuesta (con dimensiones de construcción de 8 x 14 m de forma rectangular interconectada al sedimentador y al sistema de aireación de 15.9 HP equivalente a 11,856.63 W estimando un 10 % de holgura igual 13,124.32 W). Los datos fueron obtenidos mediante ecuaciones tomadas de la literatura.

Ibero-american International University > Research > Articles and Books Abierto Inglés Internet security is a major concern these days due to the increasing demand for information technology (IT)-based platforms and cloud computing. With its expansion, the Internet has been facing various types of attacks. Viruses, denial of service (DoS) attacks, distributed DoS (DDoS) attacks, code injection attacks, and spoofing are the most common types of attacks in the modern era. Due to the expansion of IT, the volume and severity of network attacks have been increasing lately. DoS and DDoS are the most frequently reported network traffic attacks. Traditional solutions such as intrusion detection systems and firewalls cannot detect complex DDoS and DoS attacks. With the integration of artificial intelligence-based machine learning and deep learning methods, several novel approaches have been presented for DoS and DDoS detection. In particular, deep learning models have played a crucial role in detecting DDoS attacks due to their exceptional performance. This study adopts deep learning models including recurrent neural network (RNN), long short-term memory (LSTM), and gradient recurrent unit (GRU) to detect DDoS attacks on the most recent dataset, CICDDoS2019, and a comparative analysis is conducted with the CICIDS2017 dataset. The comparative analysis contributes to the development of a competent and accurate method for detecting DDoS attacks with reduced execution time and complexity. The experimental results demonstrate that models perform equally well on the CICDDoS2019 dataset with an accuracy score of 0.99, but there is a difference in execution time, with GRU showing less execution time than those of RNN and LSTM.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Traffic accidents present significant risks to human life, leading to a high number of fatalities and injuries. According to the World Health Organization’s 2022 worldwide status report on road safety, there were 27,582 deaths linked to traffic-related events, including 4448 fatalities at the collision scenes. Drunk driving is one of the leading causes contributing to the rising count of deadly accidents. Current methods to assess driver alcohol consumption are vulnerable to network risks, such as data corruption, identity theft, and man-in-the-middle attacks. In addition, these systems are subject to security restrictions that have been largely overlooked in earlier research focused on driver information. This study intends to develop a platform that combines the Internet of Things (IoT) with blockchain technology in order to address these concerns and improve the security of user data. In this work, we present a device- and blockchain-based dashboard solution for a centralized police monitoring account. The equipment is responsible for determining the driver’s impairment level by monitoring the driver’s blood alcohol concentration (BAC) and the stability of the vehicle. At predetermined times, integrated blockchain transactions are executed, transmitting data straight to the central police account. This eliminates the need for a central server, ensuring the immutability of data and the existence of blockchain transactions that are independent of any central authority. Our system delivers scalability, compatibility, and faster execution times by adopting this approach. Through comparative research, we have identified a significant increase in the need for security measures in relevant scenarios, highlighting the importance of our suggested model.

According to the World Health Organization’s 2022 worldwide status report on road safety, there were 27,582 deaths linked to traffic-related events, including 4448 fatalities at the collision scenes. Drunk driving is one of the leading causes contributing to the rising count of deadly accidents. Current methods to assess driver alcohol consumption are vulnerable to network risks, such as data corruption, identity theft, and man-in-the-middle attacks. In addition, these systems are subject to security restrictions that have been largely overlooked in earlier research focused on driver information. This study intends to develop a platform that combines the Internet of Things (IoT) with blockchain technology in order to address these concerns and improve the security of user data. In this work, we present a device- and blockchain-based dashboard solution for a centralized police monitoring account. The equipment is responsible for determining the driver’s impairment level by monitoring the driver’s blood alcohol concentration (BAC) and the stability of the vehicle. At predetermined times, integrated blockchain transactions are executed, transmitting data straight to the central police account. This eliminates the need for a central server, ensuring the immutability of data and the existence of blockchain transactions that are independent of any central authority. Our system delivers scalability, compatibility, and faster execution times by adopting this approach. Through comparative research, we have identified a significant increase in the need for security measures in relevant scenarios, highlighting the importance of our suggested model.

Ibero-american International University > Research > Articles and books Abierto Inglés Ubiquitous data monitoring and processing with minimal latency is one of the crucial challenges in real-time and scalable applications. Internet of Things (IoT), fog computing, edge computing, cloud computing, and the edge of things are the spine of all real-time and scalable applications. Conspicuously, this study proposed a novel framework for a real-time and scalable application that changes dynamically with time. In this study, IoT deployment is recommended for data acquisition. The Pre-Processing of data with local edge and fog nodes is implemented in this study. The threshold-oriented data classification method is deployed to improve the intrusion detection mechanism’s performance. The employment of machine learning-empowered intelligent algorithms in a distributed manner is implemented to enhance the overall response rate of the layered framework. The placement of respondent nodes near the framework’s IoT layer minimizes the network’s latency. For economic evaluation of the proposed framework with minimal efforts, EdgeCloudSim and FogNetSim++ simulation environments are deployed in this study. The experimental results confirm the robustness of the proposed system by its improvised threshold-oriented data classification and intrusion detection approach, improved response rate, and prediction mechanism. Moreover, the proposed layered framework provides a robust solution for real-time and scalable applications that changes dynamically with time.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés A novel approach is presented in this study for the classification of lower limb disorders, with a specific emphasis on the knee, hip, and ankle. The research employs gait analysis and the extraction of PoseNet features from video data in order to effectively identify and categorize these disorders. The PoseNet algorithm facilitates the extraction of key body joint movements and positions from videos in a non-invasive and user-friendly manner, thereby offering a comprehensive representation of lower limb movements. The features that are extracted are subsequently standardized and employed as inputs for a range of machine learning algorithms, such as Random Forest, Extra Tree Classifier, Multilayer Perceptron, Artificial Neural Networks, and Convolutional Neural Networks. The models undergo training and testing processes using a dataset consisting of 174 real patients and normal individuals collected at the Tehsil Headquarter Hospital Sadiq Abad. The evaluation of their performance is conducted through the utilization of K-fold cross-validation. The findings exhibit a notable level of accuracy and precision in the classification of various lower limb disorders. Notably, the Artificial Neural Networks model achieves the highest accuracy rate of 98.84%. The proposed methodology exhibits potential in enhancing the diagnosis and treatment planning of lower limb disorders. It presents a non-invasive and efficient method of analyzing gait patterns and identifying particular conditions.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Cricket has a massive global following and is ranked as the second most popular sport globally, with an estimated 2.5 billion fans. Batting requires quick decisions based on ball speed, trajectory, fielder positions, etc. Recently, computer vision and machine learning techniques have gained attention as potential tools to predict cricket strokes played by batters. This study presents a cutting-edge approach to predicting batsman strokes using computer vision and machine learning. The study analyzes eight strokes: pull, cut, cover drive, straight drive, backfoot punch, on drive, flick, and sweep. The study uses the MediaPipe library to extract features from videos and several machine learning and deep learning algorithms, including random forest (RF), support vector machine, k-nearest neighbors, decision tree, linear regression, and long short-term memory to predict the strokes. The study achieves an outstanding accuracy of 99.77% using the RF algorithm, outperforming the other algorithms used in the study. The k-fold validation of the RF model is 95.0% with a standard deviation of 0.07, highlighting the potential of computer vision and machine learning techniques for predicting batsman strokes in cricket. The study’s results could help improve coaching techniques and enhance batsmen’s performance in cricket, ultimately improving the game’s overall quality.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Classification is a commonly used technique in data mining and is applied in various fields such as sentiment analysis, fraud detection, and fault diagnosis. Multiclass classification, which involves more than two classes, is more complex than binary classification. There are mainly two ways to approach multiclass classification, one is to expand the binary classifier into a multiclass classifier through various strategies and the other is to divide the multiclass classification problem into multiple binary problems (binarization). Two popular approaches for binarization are One vs One (OvO) and One vs All (OvA). It is simpler to aggregate the outputs of all binary classifiers as the number of classifiers decreases. However, it causes an imbalance of positive and negative sample numbers, which affects the classification effect of each binary classifier. In this article, we contribute to the field of ensemble learning and multi-class classification by proposing a new method called Ensemble Partition Sampling (EPS). This article presents a new approach to multiclass classification using an "Ensemble Partition Sampling" method within the "one-vs-all" (OvA) framework. The primary goal of this method is to tackle the problem of data imbalance by incorporating ensemble learning and preprocessing techniques into each binary dataset. The study found that Ensemble Partition Sampling (EPS) is the most effective method for imbalanced and multiclass imbalanced classification, outperforming other methods including OvA, SMOTE, k-means-SMOTE, Bagging-RB, DES-MI, OvO-EASY, and OvO-SMB. The study used CART, Random Forest, and SVM as classifiers, and the results consistently showed that EPS outperformed all other algorithms. The findings suggest that EPS is a highly effective method for improving classification performance in imbalanced and multiclass imbalanced datasets.

Hybrid membranes with three different thicknesses, PMDS_C1, PMDS_C2, and PMDS_C3 (0.21 ± 0.03 mm, 0.31 ± 0.05 mm, and 0.48 ± 0.07 mm), were synthesized by the sol–gel method using polydimethylsiloxane, hydroxy-terminated, and cyanopropyltriethoxysilane. The presence of cyano, methyl, and silicon-methyl groups was confirmed by FTIR analysis. Contact angle analysis revealed the membranes’ hydrophilic nature. Solvent resistance tests conducted under vortex and ultrasonic treatments (45 and 60 min) demonstrated a preference order of acetonitrile > methanol > water. Furthermore, the membranes exhibited stability over 48 h when exposed to different pH conditions (1, 3, 6, and 9), with negligible mass losses below 1%. The thermogravimetric analysis showed that the material was stable until 400 °C. Finally, the sorption analysis showed its capacity to detect furfural, 2-furylmethylketone, 5-methylfurfural, and 2-methyl 2-furoate. The thicker membrane was able to adsorb and slightly desorb a higher concentration of furanic compounds due to its high polarity provided by the addition of the cyano groups. The results indicated that the membranes may be suitable for sorbent materials in extracting and enriching organic compounds.

This study explores the triggering factors of anemia among pregnant females in India, utilizing data from the Demographic and Health Survey 2019–21. Chi-squared and gamma tests were conducted to find out the relationship between anemia and various socioeconomic and sociodemographic elements. Furthermore, ordinal logistic regression and multinomial logistic regression were used to gain deeper insight into the factors that affect anemia among pregnant women in India. According to these findings, anemia affects about 50% of pregnant women in India. Anemia is significantly associated with various factors such as geographical location, level of education, and wealth index. The results of our study indicate that enhancing education and socioeconomic status may serve as viable approaches for mitigating the prevalence of anemia disease developed in pregnant females in India. Employing both Ordinal and Multinominal logistic regression provides a more comprehensive understanding of the risk factors associated with anemia, enabling the development of targeted interventions to prevent and manage this health condition. This paper aims to enhance the efficacy of anemia prevention and management strategies for pregnant women in India by offering an in-depth understanding of the causative factors of anemia.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés A new artificial intelligence-based approach is proposed by developing a deep learning (DL) model for identifying the people who violate the face mask protocol in public places. To achieve this goal, a private dataset was created, including different face images with and without masks. The proposed model was trained to detect face masks from real-time surveillance videos. The proposed face mask detection (FMDNet) model achieved a promising detection of 99.0% in terms of accuracy for identifying violations (no face mask) in public places. The model presented a better detection capability compared to other recent DL models such as FSA-Net, MobileNet V2, and ResNet by 24.03%, 5.0%, and 24.10%, respectively. Meanwhile, the model is lightweight and had a confidence score of 99.0% in a resource-constrained environment. The model can perform the detection task in real-time environments at 41.72 frames per second (FPS).

The organic polymer known as Polypyrrole (Ppy) is synthesized when pyrrole monomers are polymerized. Excellent thermal stability, superior electrical conductivity, and environmental stability are all characteristics of Polypyrrole. Chemical oxidative polymerization was used to synthesize Ppy using Ferric chloride (FeCl3) as an oxidizing agent and surfactant CTAB in aqueous solution. Oxidant (FeCl3) to pyrrole varied in different molar ratios (2, 3, 4 and 5). It was found that increasing this ratio up to 4 increases PPy's conductivity. XRD, FTIR, and SEM were used to characterize Ppy. The conductive nature of Ppy was studied by I–V characteristics. The best conductive polymer is studied for the NH3 gas response.

In this context, the optimization of the Logistic Regression, Random Forest, and Neural Network classifiers, together with different techniques, attributes, and algorithms (Hyperparameters, SMOTE, SMOTE_SVM, and ADASYN) resulted in a set of metrics for decision-making, prioritizing the reduction of false negatives. The best model was the Neural Network model in combination with SMOTE_SVM, obtaining a recall index of 0.75 and an f1-Score of 0.60. Likewise, the robustness of the Random Forest classifier for imbalanced data was demonstrated by achieving, with an optimal threshold of 0.427, very similar metrics to those obtained by the consensus of the three best models found. This demonstrates that, for Random Forest, the optimal prediction probability threshold is an excellent alternative to resampling techniques with different optimal thresholds. Finally, it is hoped that this research paper will contribute to boost the application of this simple but powerful technique, which is highly underrated with respect to data resampling techniques for imbalanced data.

For this purpose, multiple routing techniques exist to ensure security and privacy in IoT Systems. One such technique is the routing protocol for low power and lossy networks (RPL) which is an IPv6 protocol commonly used for routing in IoT systems. Formal modeling of an IoT system can validate the reliability, accuracy, and consistency of the system. This paper presents the formal modeling of RPL protocol and the analysis of its security schemes using colored Petri nets that applies formal validation and verification for both the secure and non-secure modes of RPL protocol. The proposed approach can also be useful for formal modeling-based verification of the security of the other communication protocols.

Ibero-american International University > Research > Articles and books Abierto Inglés A high penetration of renewable energy (RE) in utility grids creates the problems of power system flexibility, high transmission losses, and voltage variations. These problems can be solved using a hybrid combination of transmission network restructuring and optimal placement of distributed energy generator (DEG) units. Hence, this work investigated a technologically and economically feasible solution for improving the flexibility of power networks and reducing losses in a practical transmission utility network by implementing a restructuring of the network and optimal deployment of the distributed energy generators (DEGs). Two solutions for this network restructuring were proposed. Furthermore, a grid-oriented genetic algorithm (GOGA) was designed by combining the conventional genetic algorithm (GA) and mathematical solutions to identify optimal DEG placement. A power system restructuring and GOGA flexibility index (PSRGFI) was formulated for the assessment of network flexibility. A cost–benefit assessment was also performed to estimate the payback period for the investment required for restructuring of the network and DEG placement. The least-square approximation technique was applied for load projection for the year 2031 considering the base year 2021. It was established that minimization of transmission losses, reduction in voltage deviations, and improvement of network flexibility were achieved through hybrid application of network restructuring and DEG placement using GOGA. A network loss saving of 61.19 MW was achieved via optimal restructuring and GOGA. For the projected year 2031, the PSRGFI increased from 30.94 to 132.78 after the placement of DEGs using GOGA and optimal restructuring, indicating that network flexibility increased significantly. The payback period for the investment was very small, equal to 0.985 years. The performance of the designed method was superior to the GA-based method, simulated annealing technique, and bee colony algorithm (BCA) used for placement of DEG units in the test network. The study was completed using MATLAB software, considering data from a practical transmission network owned by Rajasthan Rajya Vidyut Prasaran Nigam Ltd. (RVPN), India.

Ibero-american International University > Research > Articles and Books Abierto Inglés Forecasting of sediment load (SL) is essential for reservoir operations, design of water resource structures, risk management, water resource planning and for preventing natural disasters in the river basin systems. Direct measurement of SL is difficult, labour intensive, and expensive. The development of an accurate and reliable model for forecasting the SL is required. Sediment transport is highly non-linear and is influenced by a variety of factors. Forecasting of the SL using various conventional methods is not highly accurate because of the association of various complex phenomena. In this study, major key factors such as rock type (RT), relief (R), rainfall (RF), water discharge (WD), temperature (T), catchment area (CA), and SL are recognized in developing the one-step-ahead SL forecasting model in the Mahanadi River (MR), which is among India’s largest rivers. Artificial neural networks (ANN) in conjunction with multi-objective genetic algorithm (ANN-MOGA)-based forecasting models were developed for forecasting the SL in the MR. The ANN-MOGA model was employed to optimize the two competing objective functions (bias and error variance) with simultaneous optimization of all associated ANN parameters. The performances of the proposed novel model were finally compared to other existing methods to verify the forecasting capability of the model. The ANN-MOGA model improved the performance by 12.81% and 10.19% compared to traditional AR and MAR regression models, respectively. The results suggested that hybrid ANN-MOGA models outperform traditional autoregressive and multivariate autoregressive forecasting models. Overall, hybrid ANN-MOGA intelligent techniques are recommended for the forecasting of SL in rivers Yadav, Arvind and Ali Albahar, Marwan and Chithaluru, Premkumar and Singh, Aman and Alammari, Abdullah and Kumar, Gogulamudi Vijay and Miró Vera, Yini Airet UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, aman.singh@uneatlantico.es, UNSPECIFIED, UNSPECIFIED, yini.miro@uneatlantico.es

Over a trillion bytes of data are generated and shared on social media through the internet in a single day, and the authenticity of digital data is currently a major problem. Cryptography and image watermarking are domains that provide multiple security services, such as authenticity, integrity, and privacy. In this paper, a digital image watermarking technique is proposed that employs the least significant bit (LSB) and canny edge detection method. The proposed method provides better security services and it is computationally less expensive, which is the demand of today’s world. The major contribution of this method is to find suitable places for watermarking embedding and provides additional watermark security by scrambling the watermark image. A digital image is divided into non-overlapping blocks, and the gradient is calculated for each block. Then convolution masks are applied to find the gradient direction and magnitude, and non-maximum suppression is applied. Finally, LSB is used to embed the watermark in the hysteresis step. Furthermore, additional security is provided by scrambling the watermark signal using our chaotic substitution box. The proposed technique is more secure because of LSB’s high payload and watermark embedding feature after a canny edge detection filter. The canny edge gradient direction and magnitude find how many bits will be embedded. To test the performance of the proposed technique, several image processing, and geometrical attacks are performed.

For this purpose, four different models are utilized to examine the impact of innovative HRM department practices on the performance of small and medium enterprises (SMEs) in a country. The dependent variable, firm performance, is proxified by different variables such as labor productivity, product innovation, process innovation, and marketing innovation. For empirical analysis, primary data are collected using a questionnaire. Estimation is conducted using ordinary least squares (OLS) and logit regression techniques. The estimated results indicate that most innovative HRM practices have a statistically significant impact on firm performance in terms of labor productivity, product, process, and marketing innovations. These results imply that SMEs in a country may observe the benefits of devoting greater attention to innovative HRM practices to achieve their future growth potential.

El Sistema de Investigación de la Universidad Estatal a Distancia (UNED) ha buscado, desde su creación, propiciar una dinámica sistémica para la gestión de sus proyectos, apoyada en herramientas tecnológicas diseñadas a la medida. Esta perspectiva reta la visión tradicional de gestión de proyectos de investigación y abre posibilidades de innovación en este ámbito. Así, surge Gestiona, un software en línea para la captura de la información producida por los proyectos pertenecientes a dicho sistema de investigación. Como objetivo se ha buscado la mejora continua de Gestiona y su adaptación a los cambios del sistema de investigación de la UNED, considerando como criterio de efectividad la mínima pérdida de información posible a partir de los datos generados por los proyectos. El presente trabajo muestra cómo, una indagación sistémica del comportamiento de los actores que intervienen en los proyectos, ha permitido la mejora continua de la herramienta y la captura de datos relevantes en Gestiona, para la toma de decisiones por parte de las personas gestoras de los proyectos de investigación. Los resultados obtenidos muestran la efectividad de la indagación sistémica como una alternativa para la mejora continua de la gestión de proyectos. Asimismo, se presentan oportunidades de mejora emergentes como una característica valiosa propia del proceso de indagación sistémica.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Agriculture is a critical domain, where technology can have a significant impact on increasing yields, improving crop quality, and reducing environmental impact. The use of renewable energy sources such as solar power in agriculture has gained momentum in recent years due to the potential to reduce the carbon footprint of farming operations. In addition to providing a source of clean energy, solar tracking systems can also be used for remote weather monitoring in the agricultural field. The ability to collect real-time data on weather parameters such as temperature, humidity, and rainfall can help farmers make informed decisions on irrigation, pest control, and other crop management practices. The main idea of this study is to present a system that can improve the efficiency of solar panels to provide constant power to the sensor in the agricultural field and transfer real-time data to the app. This research presents a mechanism to improve the arrangement of a photovoltaic (PV) array with solar power and to produce maximum energy. The proposed system changes its direction in two axes (azimuth and elevation) by detecting the difference between the position of the sun and the panel to track the sun using a light-dependent resistor. A testbed with a hardware experimental setup is designed to test the system’s capability to track according to the position of the sun effectively. In the end, real-time data are displayed using the Android app, and the weather data are transferred to the app using a GSM/WiFi module. This research improves the existing system, and results showed that the relative increase in power generation was up to 52%. Using intelligent artificial intelligence techniques with the QoS algorithm, the quality of service produced by the existing system is improved.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés An Internet of Things (IoT) network is prone to many ways of threatening individuals. IoT sensors are lightweight, lack complicated security protocols, and face threats to privacy and confidentiality. Hackers can attack the IoT network and access personal information and confidential data for blackmailing, and negatively manipulate data. This study aims to propose an IoT threat protection system (IoTTPS) to protect the IoT network from threats using an ensemble model RKSVM, comprising a random forest (RF), K nearest neighbor (KNN), and support vector machine (SVM) model. The software-defined networks (SDN)-based IoT network datasets such as KDD cup 99, NSL-KDD, and CICIDS are used for threat detection based on machine learning. The experimental phase is conducted by using a decision tree (DT), logistic regression (LR), Naive Bayes (NB), RF, SVM, gradient boosting machine (GBM), KNN, and the proposed ensemble RKSVM model. Furthermore, performance is optimized by adding a grid search hyperparameter optimization technique with K-Fold cross-validation. As well as the NSL-KDD dataset, two other datasets, KDD and CIC-IDS 2017, are used to validate the performance. Classification accuracies of 99.7%, 99.3%, 99.7%, and 97.8% are obtained for DoS, Probe, U2R, and R2L attacks using the proposed ensemble RKSVM model using grid search and cross-fold validation. Experimental results demonstrate the superior performance of the proposed model for IoT threat detection.

The experimental phase is conducted by using a decision tree (DT), logistic regression (LR), Naive Bayes (NB), RF, SVM, gradient boosting machine (GBM), KNN, and the proposed ensemble RKSVM model. Furthermore, performance is optimized by adding a grid search hyperparameter optimization technique with K-Fold cross-validation. As well as the NSL-KDD dataset, two other datasets, KDD and CIC-IDS 2017, are used to validate the performance. Classification accuracies of 99.7%, 99.3%, 99.7%, and 97.8% are obtained for DoS, Probe, U2R, and R2L attacks using the proposed ensemble RKSVM model using grid search and cross-fold validation. Experimental results demonstrate the superior performance of the proposed model for IoT threat detection.

La energía es un factor que influye determinadamente al cambio climático contribuyendo en un 60% a las emisiones de efecto invernadero, por lo que los gobiernos del mundo entero se han comprometido a disminuir estas emisiones para lograr el objetivo 7 del desarrollo sostenible 2030 de las Naciones Unidas: Energía asequible y no contaminante. Por ello, miles de proyectos se han llevado a cabo desde la Conferencia en Río de Janeiro, en 2012.Desafortunadamente, la mayoría de las empresas que llevan a cabo estos proyectos con tecnologías energéticas sustentables, no contemplan una evaluación integral de los proyectos, por lo que durante la implementación se presentan problemas legales, sociales y ambiéntales ente otros, ocasionando suspensión de obra de manera temporal o definitiva con pérdidas financieras considerables.En el presente trabajo se analizan los procesos aplicados por las empresas constructoras sobre la implementación de los proyectos de energía, revisando el grado de integralidad de las variables social, ambiental, político, legal, técnico, tecnológico, financiero, económico y comercial que garantice el éxito del proyecto. Debido a que llevar a cabo una metodología como la que se propone en proyectos de gran envergadura requiere de grandes inversiones monetarias, la validación se llevará a cabo mediante la opinión de expertos en energía de las empresas seleccionadas por el investigador, analizando los datos obtenidos para determinar las variables que se emplean en la implementación. Es decir, la implementación de la metodología no es del alcance de esta propuesta.La metodología de investigación aplicada será estudio de campo, con un diseño cualitativo descriptivo y transversal; tomando una población de empresas enfocadas a proyectos de energía con criterios de inclusión y exclusión, considerando las variables de estudio que impactan en el desarrollo de la metodología. Si bien encontramos propuestas metodológicas anteriores, dentro de ellas se desarrollan los diversos aspectos que comprenden el proyecto de manera aislada, pero los aspectos transversales, que conforman el proyecto como un sistema interrelacionado, no se analizan de manera integral.Adicionalmente, el estudio se complementa con la experiencia de expertos que han desarrollado previamente proyectos de esta naturaleza, permitiendo el diseño del proceso metodológico innovador para la evaluación integral de proyectos de energía que mitigue los impactos negativos.

In this investigation, microwave radiation was used alongside a combination of Ni powder, Si powder, and La2O3 (Lanthanum oxide) powder to create surface cladding on SS-304 steel. To complete the microwave cladding process, 900 W at 2.45 GHz was used for 120 s. “Response surface methodology (RSM)” was utilized to attain the optimal combination of microwave cladding process parameters. The surface hardness of the cladding samples was taken as a response. The optimal combination of microwave cladding process parameters was found to be Si (wt.%) of 19.28, a skin depth of 4.57 µm, irradiation time of 118 s, and La2O3 (wt.%) of 11 to achieve a surface hardness of 287.25 HV. Experimental surface hardness at the corresponding microwave-cladding-process parameters was found to be 279 HV. The hardness of SS-304 was improved by about 32.85% at the optimum combination of microwave cladding process parameters. The SEM and optical microscopic images showed the presence of Si, Ni, and La2O3 particles. SEM images of the “cladding layer and surface” showed the “uniform cladding layer” with “fewer dark pixels” (yielding higher homogeneity). Higher homogeneity reduced the dimensional deviation in the developed cladding surface. XRD of the cladded surface showed the presence of FeNi, Ni2Si, FeNi3, NiSi2, Ni3C, NiC, and La2O3 phases. The “wear rate and coefficient of friction” of the developed cladded surface with 69.72% Ni, 19.28% Si, and 11% La2O3 particles were found to be 0.00367 mm3/m and 0.312, respectively. “Few dark spots” were observed on the “corroded surface”. These “dark spots” displayed “some corrosion (corrosion weight loss 0.49 mg)” in a “3.5 wt.% NaCl environment”.

This paper presents the enhancement of power system dynamic stability through the optimal design of a power system stabilizer and UPFC using an ant lion optimization (ALO) technique to enhance transmission line capacity. The gained damping ratio, eigenvalue and time domain results of the suggested ALO technique were compared with a base case system, ALO-based PSS and ALO-based PSS-UPFC to test the effectiveness of the proposed system in different loading cases. Eigenvalues gained from an ant lion approach-based UPFC with a PSS and a base case system are compared to examine the robustness of the ALO method for various loading conditions. Thus, this paper addresses the mechanism regarding the power system dynamic stability of transmission lines by integrating the optimal size of a PSS and UPFC into the power system. Therefore, the main contribution of this manuscript is the optimal coordination of a power system stabilizer, power oscillation damper and unified power flow using ant lion optimization for the mitigation of low-frequency oscillation.

Los cambios provocados por la globalización han construido una nueva realidad para los medios de producción y comunicación, la calidad de vida y el comportamiento, favoreciendo el surgimiento de proyectos en todo el mundo. Durante el gobierno del Partido de los Trabajadores (2003-2016), Brasil siguió esta tendencia, transformándose en un gran sitio de construcción, donde la ingeniería de exploración de petróleo y gas asumió un papel importante para la economía nacional. La alta demanda mundial de energía y el descubrimiento de la provincia del presal permitirían al país convertirse en exportador de energía y superpotencia para el año 2030, definiendo el carácter estratégico de los megaproyectos de exploración de petróleo y gas en la Cuenca de Santos, São Paulo. El programa de gobierno en la era del PT ofreció a Brasil un terreno fértil para el desarrollo económico, pero también para la ilegalidad, cuando una nueva realidad sacada a la luz en 2014 por la Operación Lava Jato desencadenó el mayor escándalo de corrupción en la historia de Brasil. La combinación de complejidad y corrupción provocó retrasos en la entrega de petróleo al mercado de consumo y enormes pérdidas financieras. La situación exigía iniciativas de apoyo a la gestión de horarios que estén a la altura del desafío, donde la respuesta esperada es la aplicación de un método de análisis de horarios – el Método FORTE v. 1.0 – responsable de la primera iniciativa integrada dirigida al cumplimiento, gestión de proyectos y conocimiento corporativo, ajustada a la realidad de los grandes proyectos de ingeniería en Brasil. La situación requería una solución de TI con diferentes características – Oracle Primavera P6 – y el resultado de la iniciativa es un conjunto de logros más allá de la gestión de proyectos, permeando todo el tejido organizacional.

Detecting LSS is a significantly important yet difficult task. It is detected by analyzing the area of the anteroposterior diameter of the patient’s lumbar spine. Currently, the versatility and accuracy of LSS segmentation algorithms are limited. The objective of this research is to use magnetic resonance imaging (MRI) to automatically categorize LSS. This study presents a convolutional neural network (CNN)-based method to detect LSS using MRI images. Radiological grading is performed on a publicly available dataset. Four regions of interest (ROIs) are determined to diagnose LSS with normal, mild, moderate, and severe gradings. The experiments are performed on 1545 axial-view MRI images. Furthermore, two datasets—multi-ROI and single-ROI—are created. For training and testing, an 80:20 ratio of randomly selected labeled datasets is used, with fivefold cross-validation. The results of the proposed model reveal a 97.01% accuracy for multi-ROI and 97.71% accuracy for single-ROI. The proposed computer-aided diagnosis approach can significantly improve diagnostic accuracy in everyday clinical workflows to assist medical experts in decision making. The proposed CNN-based MRI image segmentation approach shows its efficacy on a variety of datasets.

Ibero-american International University > Research > Articles and Books Abierto Inglés COVID-19 is an infectious disease caused by the deadly virus SARS-CoV-2 that affects the lung of the patient. Different symptoms, including fever, muscle pain and respiratory syndrome, can be identified in COVID-19-affected patients. The disease needs to be diagnosed in a timely manner, otherwise the lung infection can turn into a severe form and the patient’s life may be in danger. In this work, an ensemble deep learning-based technique is proposed for COVID-19 detection that can classify the disease with high accuracy, efficiency, and reliability. A weighted average ensemble (WAE) prediction was performed by combining three CNN models, namely Xception, VGG19 and ResNet50V2, where 97.25% and 94.10% accuracy was achieved for binary and multiclass classification, respectively. To accurately detect the disease, different test methods have been proposed and developed, some of which are even being used in real-time situations. RT-PCR is one of the most successful COVID-19 detection methods, and is being used worldwide with high accuracy and sensitivity. However, complexity and time-consuming manual processes are limitations of this method. To make the detection process automated, researchers across the world have started to use deep learning to detect COVID-19 applied on medical imaging. Although most of the existing systems offer high accuracy, different limitations, including high variance, overfitting and generalization errors, can be found that can degrade the system performance. Some of the reasons behind those limitations are a lack of reliable data resources, missing preprocessing techniques, a lack of proper model selection, etc., which eventually create reliability issues. Reliability is an important factor for any healthcare system. Here, transfer learning with better preprocessing techniques applied on two benchmark datasets makes the work more reliable.

This work therefore proposes to study the different possible scenarios for the replacement of light fuel oil (LFO) thermal power plants connected to the electrical network in northern Cameroon by renewable energy plants. Several scenarios such as the combination of solar photovoltaic (PV) with a pumped hydro storage system (PHSS), Wind and PHSS and PV-Wind-PHSS have been studied. The selected scenarios are evaluated based on two factors such as the system’s total cost (TC) and the loss of load probability (LOLP). To achieve the results, metaheuristics such the non-dominated sorting whale optimization algorithm (NSWOA) and non-dominated sorting genetic algorithm-II (NSGA-II) have been applied under MATLAB software. The optimal sizing of the components was done using hourly meteorological data and the hourly power generated by the thermal power plants connected to the electrical grid. Both algorithms provided satisfactory results. However, the total cost in the PV-PHSS, Wind-PHSS, and PV-Wind-PHSS scenarios with NSWOA is, respectively, 1%, 6%, and 0.2% lower than with NSGA-II. According to NSWOA results, the total cost for the PV-Wind-PHSS scenario at LOLP 0% is 4.6% and 17% less than the Wind-PHS and PV-PHSS scenarios, respectively. The profitability study of all three scenarios showed that the project is profitable regardless of the scenario considered.

This is achieved by optimal deployment of optimally sized renewable energy (RE) generators using GOMOHSA. Performance indexes such as active power loss minimization index (APMLI), the reactive power loss minimization index (RPMLI), and the total voltage deviation improvement index (TVDII) are introduced to evaluate the health of the test network with different load scenarios. Performance of proposed GOMOHSA has been tested for five different operating scenarios of loads and RE generation. It is established that the proposed GOMOHSA finds the optimal deployment of optimally sized RE generators, and the investment cost of deployment of these RE generators can be recovered within a time period that is less than 5 years. Performance of GOMOHSA is superior compared to a conventional genetic algorithm (GA) in terms of performance indexes, RE generator capacity, payback period, and parameter sensitivity. Study is performed using MATLAB software for loading scenario of base year 2021 and projected year 2031.

Performance indexes such as active power loss minimization index (APMLI), the reactive power loss minimization index (RPMLI), and the total voltage deviation improvement index (TVDII) are introduced to evaluate the health of the test network with different load scenarios. Performance of proposed GOMOHSA has been tested for five different operating scenarios of loads and RE generation. It is established that the proposed GOMOHSA finds the optimal deployment of optimally sized RE generators, and the investment cost of deployment of these RE generators can be recovered within a time period that is less than 5 years. Performance of GOMOHSA is superior compared to a conventional genetic algorithm (GA) in terms of performance indexes, RE generator capacity, payback period, and parameter sensitivity. Study is performed using MATLAB software for loading scenario of base year 2021 and projected year 2031.

Ibero-american International University > Research > Articles and books Abierto Inglés In this paper, the electrical parameters of a hybrid power system made of hybrid renewable energy sources (HRES) generation are primarily discussed. The main components of HRES with energy storage (ES) systems are the resources coordinated with multiple photovoltaic (PV) cell units, a biogas generator, and multiple ES systems, including superconducting magnetic energy storage (SMES) and pumped hydro energy storage (PHES). The performance characteristics of the HRES are determined by the constant power generation from various sources, as well as the shifting load perturbations. Constant power generation from a variety of sources, as well as shifting load perturbations, dictate the HRES’s performance characteristics. As a result of the fluctuating load demand, there will be steady generation but also fluctuating frequency and power. A suitable control strategy is therefore needed to overcome the frequency and power deviations under the aforementioned load demand and generation conditions. An integration in the environment of fractional order (FO) calculus for proportion-al-integral-derivative (PID) controllers and fuzzy controllers, referred to as FO-Fuzzy-PID controllers, tuned with the opposition-based whale optimization algorithm (OWOA), and compared with QOHSA, TBLOA, and PSO has been proposed to control the frequency deviation and power deviations in each power generation unites. The results of the frequency deviation obtained by using FO-fuzzy-PID controllers with OWOA tuned are 1.05%, 2.01%, and 2.73% lower than when QOHSA, TBLOA, and PSO have been used to tune, respectively. Through this analysis, the algorithm’s efficiency is determined. Sensitivity studies are also carried out to demonstrate the robustness of the technique under consideration in relation to changes in the sizes of the HRES and ES system parameters.

La elaboración de materiales biodegradables surge como alternativa para disminuir la contaminación causada por los desechos plásticos, los cuales se acumulan en el ambiente a gran velocidad, como respuesta se buscan materiales biodegradables que permitan el sostenimiento del ecosistema a través de materiales renovables. El estudio se enfocó en la optimización de la formulación mediante un diseño experimental que permitió obtener una combinación óptima de los ingredientes para un bioplástico con las mejores propiedades mecánicas y de barrera de un material para envases, destacando el enfoque experimental Box-Behnken de superficie de respuesta que incluye al almidón de yuca como un elemento muy versátil y útil en la industria mejorando la textura, la apariencia y la calidad del material final; El aceite esencial de limón que puede conferir propiedades antimicrobianas y mejorar la estabilidad térmica del bioplástico y el colágeno de escamas de pescado con una excelente capacidad para formar películas debido a su contenido en aminoácidos y su estructura molecular sumando a las cualidades del bioplástico tener una buena resistencia y flexibilidad, obteniendo un material con propiedades parecidas aún material de polimérico convencional. Esta información puede ser útil para futuros estudios que busquen desarrollar bioplásticos con propiedades y características similares. Sin embargo, es importante tener en cuenta que el estudio tuvo algunas limitaciones en el tiempo de biodegradación del bioplástico en condiciones de desecho por pérdida de peso y el efecto imperceptible a la concentración estipulada del aceite esencial como antimicrobiano. En general, los resultados del estudio tienen implicaciones importantes para la industria agroalimentaria, ya que los bioplásticos pueden ofrecer una alternativa más sostenible a los plásticos tradicionales.

The Secure Hash Algorithm (SHA-256) hashed value of preliminary data (block) is retained in one block along with transaction data in tree form and timestamp in a chain of blocks.

These constraints can be overcome by incorporating encryption algorithms into accepting blocks of data. In this paper, we propose a secure intelligent computational model for a large-scale interconnected IoT environment; an analytical modeling technique is considered for the proposed system. The proposed system takes advantage of the potential security feature of blockchain, which is considered the most appropriate secure communication system in an IoT. A computational model is built using the proposed blockchain technology to incorporate a secure and intelligent communication system.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The rising popularity of online shopping has led to a steady stream of new product evaluations. Consumers benefit from these evaluations as they make purchasing decisions. Many research projects rank products using these reviews, however, most of these methodologies have ignored negative polarity while evaluating products for client needs. The main contribution of this research is the inclusion of negative polarity in the analysis of product rankings alongside positive polarity. To account for reviews that contain many sentiments and different elements, the suggested method first breaks them down into sentences. This process aids in determining the polarity of products at the phrase level by extracting elements from product evaluations. The next step is to link the polarity to the review’s sentence-level features. Products are prioritized following user needs by assigning relative importance to each of the polarities. The Amazon review dataset has been used in the experimental assessments so that the efficacy of the suggested approach can be estimated. Experimental evaluation of PRUS utilizes rank score ( RS ) and normalized discounted cumulative gain ( nDCG ) score. Results indicate that PRUS gives independence to the user to select recommended list based on specific features with respect to positive or negative aspects of the products.

Ibero-american International University > Research > Articles and books Abierto Inglés This paper introduces a power quality (PQ) detection and categorization algorithm actuated by multiple signal processing techniques and rule-based decision tree (RBDT). This is aimed to recognize PQ events of simple nature and higher order multiplicity with less computational time using hybridization of the signal processing techniques. A voltage waveform with a PQ event (PQE) is processed using the Stockwell transform (ST) to compute the Stockwell PQ detection index (SPDI). The voltage waveform is also processed using the Hilbert transform (HT) to compute the Hilbert PQ detection index (HPDI). A voltage waveform is also decomposed using the Discrete Wavelet transform (DWT) to compute the classification feature index (CFI) [CFI1 to CFI4]. A combined PQ detection index (CPDI) is computed by multiplication of the SPDI, the HPDI and CFI1 to CFI4. Incidence of a PQE on a voltage signal is located with the help of a location PQ disturbance index (LPDI) which is computed by differentiating the CPDI with respect to time. CFI5, CFI6 and CFI7 are computed from the SPDI, the HPDI and the CPDI, respectively. Categorization of PQ events is performed using CFI1 to CFI7 by the rule-based decision tree (RBDT) with the help of simple decision rules. We conclude that the proposed algorithm is effective to identify the PQE with an accuracy of 98.58% in a noise-free environment and 97.62% in the presence of 20 dB SNR (signal-to-noise ratio) noise. Ten simple nature PQEs and eight combined PQ events (CPQEs) with multiplicity of two, three and four are effectively detected and categorized using the algorithm. The algorithm is also tested to detect a sag PQ event due to a line-to-ground (LG) fault incident on a practical distribution utility network. The performance of the investigated method is compared with a DWT-based technique in terms of accuracy of classification with and without noise, maximum computational time of PQ detection and multiplicity of PQE which can be effectively detected. A simulation is performed using the MATLAB software. MATLAB codes are used for modelling the PQE disturbances and the proposed algorithm using mathematical formulations.

Ibero-american International University > Research > Articles and books Cerrado Inglés Correct identification of tumor in brain images is critical for treatment. In the medical domain, class distributions of recorded data could differ with locations and require high levels of privacy while collaboratively training the deep learning (DL) models for classifications. The main aim of this paper is to propose a privacy-preserving collaborative model for the classification of brain tumor in heterogeneously distributed magnetic resonance imaging (MRI) images. In this paper, initially, an open-source dataset has been acquired and analyzed as per the required competencies. The acquired dataset has four types of MRI images: pituitary tumor, meningioma tumor, glioma tumor, and no tumor. First, the acquired dataset was analyzed using DL and transfer learning algorithms. By applying implementations of basic algorithms, better algorithms were identified for further implementations in a federated learning ecosystem. DenseNet201-based transfer learning was identified as a better neural network and further utilized for collaborative transfer learning implementations. Here, the paper also focused on developing a suitable system for a heterogeneous distributed tumor database. Heterogeneous data were converted from the available data by applying nonidentical data distribution. The study discovered that the federated DL models, involving multiple clients, exhibited superior performance compared to conventional pretrained models. The proposed framework possesses distinctive characteristics that distinguish it from existing classification methods for brain tumor identification, particularly in terms of ensuring data privacy for edge devices with limited resources. Due to these additional features, the framework stands as the optimal alternative solution for early diagnosis of brain tumor.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Railway track faults may lead to railway accidents and cause human and financial loss. Spatial, temporal, and weather elements, and wear and tear, lead to ballast, loose nuts, misalignment, and cracks leading to accidents. Manual inspection of such defects is time-consuming and prone to errors. Automatic inspection provides a fast, reliable, and unbiased solution. However, highly accurate fault detection is challenging due to the lack of public datasets, noisy data, inefficient models, etc. To obtain better performance, this study presents a novel approach that relies on mel frequency cepstral coefficient features from acoustic data. The primary objective of this study is to increase fault detection performance. As well as designing an ensemble model, we utilize selective features using chi-square(chi2) that have high importance with respect to the target class. Extensive experiments were carried out to analyze the efficiency of the proposed approach. The experimental results suggest that using 60 features, 40 original features, and 20 chi2 features produces optimal results both regarding accuracy and computational complexity. A mean accuracy score of 0.99 was obtained using the proposed approach with machine learning models using the collected data. Moreover, this performance was significantly better than that of existing approaches; however, the performance of models may vary in real-world settings.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Non-word and real-word errors are generally two types of spelling errors. Non-word errors are misspelled words that are nonexistent in the lexicon while real-word errors are misspelled words that exist in the lexicon but are used out of context in a sentence. Lexicon-based lookup approach is widely used for non-word errors but it is incapable of handling real-word errors as they require contextual information. Contrary to the English language, real-word error detection and correction for low-resourced languages like Urdu is an unexplored area. This paper presents a real-word spelling error detection and correction approach for the Urdu language. We develop an extensive lexicon of 593,738 words and use this lexicon to develop a dataset for real-word errors comprising 125562 sentences and 2,552,735 words. Based on the developed lexicon and dataset, we then develop a contextual spell checker that detects and corrects real-word errors. For the real-word error detection phase, word-gram features are used along with five machine learning classifiers, achieving a precision, recall, and F1-score of 0.84,0.79, and 0.81 respectively. We also test the proposed approach with a 40% error density. For real-word error correction, the Damerau-Levenshtein distance is used along with the n-gram model for further ranking of the suggested candidate words, achieving an accuracy of up to 83.67%.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Recent developments in quantum computing have shed light on the shortcomings of the conventional public cryptosystem. Even while Shor’s algorithm cannot yet be implemented on quantum computers, it indicates that asymmetric key encryption will not be practicable or secure in the near future. The National Institute of Standards and Technology (NIST) has started looking for a post-quantum encryption algorithm that is resistant to the development of future quantum computers as a response to this security concern. The current focus is on standardizing asymmetric cryptography that should be impenetrable by a quantum computer. This has become increasingly important in recent years. Currently, the process of standardizing asymmetric cryptography is coming very close to being finished. This study evaluated the performance of two post-quantum cryptography (PQC) algorithms, both of which were selected as NIST fourth-round finalists. The research assessed the key generation, encapsulation, and decapsulation operations, providing insights into their efficiency and suitability for real-world applications. Further research and standardization efforts are required to enable secure and efficient post-quantum encryption. When selecting appropriate post-quantum encryption algorithms for specific applications, factors such as security levels, performance requirements, key sizes, and platform compatibility should be taken into account.

Silicon photonics is rapidly evolving as an advanced chip framework for implementing quantum technologies. With the help of silicon photonics, general-purpose programmable networks with hundreds of discrete components have been developed. These networks can compute quantum states generated on-chip as well as more extraordinary functions like quantum transmission and random number generation. In particular, the interfacing of silicon photonics with complementary metal oxide semiconductor (CMOS) microelectronics enables us to build miniaturized quantum devices for next-generation sensing, communication, and generating randomness for assembling quantum computers. In this review, we assess the significance of silicon photonics and its interfacing with microelectronics for achieving the technology milestones in the next generation of quantum computers and quantum communication. To this end, especially, we have provided an overview of the mechanism of a homodyne detector and the latest state-of-the-art of measuring squeezed light along with its integration on a photonic chip. Finally, we present an outlook on future studies that are considered beneficial for the wide implementation of silicon photonics for distinct data-driven applications with maximum throughput.

Research conducted in this field has been evolving with new techniques that necessitate periodic comparative analyses. Software project success largely depends on accurate software cost estimation as it gives an idea of the challenges and risks involved in the development. The great diversity of ML and Non-ML techniques has generated a comparison and progressed into the integration of these techniques. Based on varying advantages it has become imperative to work out preferred estimation techniques to improve the project development process. This study aims to present a systematic literature review (SLR) to investigate the trends of the articles published in the recent one and a half decades and to propose a way forward. This systematic literature review has proposed a three-stage approach to plan (Tollgate approach), conduct (Likert type scale), and report the results from five renowned digital libraries. For the selected 52 articles, artificial neural network model (ANN) and constructive cost model (COCOMO) based approaches have been the favored techniques. The mean magnitude of relative error (MMRE) has been the preferred accuracy metric, software engineering, and project management are the most relevant fields, and the promise repository has been identified as the widely accessed database.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Safety critical spare parts hold special importance for aviation organizations. However, accurate forecasting of such parts becomes challenging when the data are lumpy or intermittent. This research paper proposes an artificial neural network (ANN) model that is able to observe the recent trends of error surface and responds efficiently to the local gradient for precise spare prediction results marked by lumpiness. Introduction of the momentum term allows the proposed ANN model to ignore small variations in the error surface and to behave like a low-pass filter and thus to avoid local minima. Using the whole collection of aviation spare parts having the highest demand activity, an ANN model is built to predict the failure of aircraft installed parts. The proposed model is first optimized for its topology and is later trained and validated with known historical demand datasets. The testing phase includes introducing input vector comprising influential factors that dictate sporadic demand. The proposed approach is found to provide superior results due to its simple architecture and fast converging training algorithm once evaluated against some other state-of-the-art models from the literature using related benchmark performance criteria. The experimental results demonstrate the effectiveness of the proposed approach. The accurate prediction of the cost-heavy and critical spare parts is expected to result in huge cost savings, reduce downtime, and improve the operational readiness of drones, fixed wing aircraft and helicopters. This also resolves the dead inventory issue as a result of wrong demands of fast moving spares due to human error.

Ibero-american International University > Research > Articles and books Abierto Inglés Stress is now a serious disease that exists due to changes in working life and food ecosystems around the world. In general, it is difficult for a person to know if they are under stress. According to previous research, temperature, heart rate variability (HRV), humidity, and blood pressure are used to assess stress levels with the use of instruments. With the development of sensor technology and wireless connectivity, people around the world are adopting and using smart devices. In this study, a bio signal detection device with Internet of Things (IoT) capability with a galvanic skin reaction (GSR) sensor is proposed and built for real-time stress monitoring. The proposed device is based on an Arduino controller and Bluetooth communication. To evaluate the performance of the system, physical stress is created on 10 different participants with three distinct tasks namely reading, visualizing the timer clock, and watching videos. MATLAB analysis is performed for identifying the three different levels of stress and obtaining the threshold values as if the person GSR voltage i.e., relaxed for <1.75 volts; Normal: between 1.75 and 1.44 volts and stressed: >1.44 volts. In addition, LabVIEW is used as a data acquisition system, and a Blueterm mobile application is also used to view the sensor reading received from the device through Bluetooth communication.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Disaster management is a critical area that requires efficient methods and techniques to address various challenges. This comprehensive assessment offers an in-depth overview of disaster management systems, methods, obstacles, and potential future paths. Specifically, it focuses on flood control, a significant and recurrent category of natural disasters. The analysis begins by exploring various types of natural catastrophes, including earthquakes, wildfires, and floods. It then delves into the different domains that collectively contribute to effective flood management. These domains encompass cutting-edge technologies such as big data analysis and cloud computing, providing scalable and reliable infrastructure for data storage, processing, and analysis. The study investigates the potential of the Internet of Things and sensor networks to gather real-time data from flood-prone areas, enhancing situational awareness and enabling prompt actions. Model-driven engineering is examined for its utility in developing and modeling flood scenarios, aiding in preparation and response planning. This study includes the Google Earth engine (GEE) and examines previous studies involving GEE. Moreover, we discuss remote sensing; remote sensing is undoubtedly a valuable tool for disaster management, and offers geographical data in various situations. We explore the application of Geographical Information System (GIS) and Spatial Data Management for visualizing and analyzing spatial data and facilitating informed decision-making and resource allocation during floods. In the final section, the focus shifts to the utilization of machine learning and data analytics in flood management. These methodologies offer predictive models and data-driven insights, enhancing early warning systems, risk assessment, and mitigation strategies. Through this in-depth analysis, the significance of incorporating these spheres into flood control procedures is highlighted, with the aim of improving disaster management techniques and enhancing resilience in flood-prone regions.

University of La Romana > Research > Scientific Production Abierto Inglés Artificial intelligence (AI)-based models have emerged as powerful tools in financial markets, capable of reducing investment risks and aiding in selecting highly profitable stocks by achieving precise predictions. This holds immense value for investors, as it empowers them to make data-driven decisions. Identifying current and future trends in multi-class forecasting techniques employed within financial markets, particularly profitability analysis as an evaluation metric is important. The review focuses on examining stud-ies conducted between 2018 and 2023, sourced from three prominent academic databases. A meticulous three-stage approach was employed, encompassing the systematic planning, conduct, and analysis of the se-lected studies. Specifically, the analysis emphasizes technical assessment, profitability analysis, hybrid mod-eling, and the type of results generated by models. Articles were shortlisted based on inclusion and exclusion criteria, while a rigorous quality assessment through ten quality criteria questions, utilizing a Likert-type scale was employed to ensure methodological robustness. We observed that ensemble and hybrid models with long short-term memory (LSTM) and support vector machines (SVM) are being more adopted for financial trends and price prediction. Moreover, hybrid models employing AI algorithms for feature engineering have great potential at par with ensemble techniques. Most studies only employ performance metrics and lack utilization of profitability metrics or investment or trading strategy (simulated or real-time). Similarly, research on multi-class or output is severely lacking in financial forecasting and can be a good avenue for future research.

This holds immense value for investors, as it empowers them to make data-driven decisions. Identifying current and future trends in multi-class forecasting techniques employed within financial markets, particularly profitability analysis as an evaluation metric is important. The review focuses on examining stud-ies conducted between 2018 and 2023, sourced from three prominent academic databases. A meticulous three-stage approach was employed, encompassing the systematic planning, conduct, and analysis of the se-lected studies. Specifically, the analysis emphasizes technical assessment, profitability analysis, hybrid mod-eling, and the type of results generated by models. Articles were shortlisted based on inclusion and exclusion criteria, while a rigorous quality assessment through ten quality criteria questions, utilizing a Likert-type scale was employed to ensure methodological robustness. We observed that ensemble and hybrid models with long short-term memory (LSTM) and support vector machines (SVM) are being more adopted for financial trends and price prediction. Moreover, hybrid models employing AI algorithms for feature engineering have great potential at par with ensemble techniques. Most studies only employ performance metrics and lack utilization of profitability metrics or investment or trading strategy (simulated or real-time). Similarly, research on multi-class or output is severely lacking in financial forecasting and can be a good avenue for future research.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés With a view of the post-COVID-19 world and probable future pandemics, this paper presents an Internet of Things (IoT)-based automated healthcare diagnosis model that employs a mixed approach using data augmentation, transfer learning, and deep learning techniques and does not require physical interaction between the patient and physician. Through a user-friendly graphic user interface and availability of suitable computing power on smart devices, the embedded artificial intelligence allows the proposed model to be effectively used by a layperson without the need for a dental expert by indicating any issues with the teeth and subsequent treatment options. The proposed method involves multiple processes, including data acquisition using IoT devices, data preprocessing, deep learning-based feature extraction, and classification through an unsupervised neural network. The dataset contains multiple periapical X-rays of five different types of lesions obtained through an IoT device mounted within the mouth guard. A pretrained AlexNet, a fast GPU implementation of a convolutional neural network (CNN), is fine-tuned using data augmentation and transfer learning and employed to extract the suitable feature set. The data augmentation avoids overtraining, whereas accuracy is improved by transfer learning. Later, support vector machine (SVM) and the K-nearest neighbors (KNN) classifiers are trained for lesion classification. It was found that the proposed automated model based on the AlexNet extraction mechanism followed by the SVM classifier achieved an accuracy of 98%, showing the effectiveness of the presented approach.

Ibero-american International University > Research > Articles and books Abierto Inglés This paper introduced a method using hybrid combination of network restructuring and optimal placement of optimally sized distributed generators (DG) to reduce loss and improve voltage profile in a practical transmission network for scenario of high load demand for a period of ten years. A study is performed for four study cases which includes the test transmission network without considering optimal DG placement and network restructuring, considering network restructuring, optimal placement of DG units using proposed grid parameter oriented harmony search algorithm (GPOHSA) and considering hybrid combination of network restructuring and DG placement using GPOHSA. Network restructuring is achieved by addition of a new 400 kV Grid-substation (GSS) and a 220 kV GSS along with associated transmission system. GPOHSA is obtained by a modification in the conventional harmony search algorithm (HSA) where grid coordinates are used for locating the individuals in an objective space. Performance Improvement Indicators such as real power loss reduction indicator (SPLRI), reactive power loss reduction indicator (SQLRI) and summation of node voltage deviation reduction indicator (SNVDRI) are proposed to evaluate performance of each case of study. The period of investment return is assessed to evaluate the pay back period of the investments incurred in network restructuring and DG units. It is established that hybrid combination of network restructuring and DG units placement using GPOHSA is effective to meet the increased load demand for time period of ten years with reduced losses and improved voltage profile. Investment incurred on the network restructuring and DG units placement will be recovered in a time period of 4 years. Effectiveness of the GPOHSA is better relative to the conventional genetic algorithm (GA) for DG unit placement. The study is performed using the MATLAB software on a practical transmission network in India.

Ibero-american International University > Research > Articles and Books Abierto Inglés In this paper, a novel ultra-wideband UWB antenna element with triple-band notches is proposed. The proposed UWB radiator element operates from 2.03 GHz up to 15.04 GHz with triple rejected bands at the WiMAX band (3.28–3.8 GHz), WLAN band (5.05–5.9 GHz), and X-band (7.78–8.51 GHz). In addition, the radiator supports the Bluetooth band (2.4–2.483 GHz). Three different techniques were utilized to obtain the triple-band notches. An alpha-shaped coupled line with a stub-loaded resonator (SLR) band stop filter was inserted along the main feeding line before the radiator to obtain a WiMAX band notch characteristic. Two identical U-shaped slots were etched on the proposed UWB radiator to achieve WLAN band notch characteristics with a very high degree of selectivity. Two identical metallic frames of an octagon-shaped electromagnetic band gap structure (EBG) were placed along the main feeding line to achieve the notch characteristic with X-band satellite communication with high sharpness edges. A novel UWB multiple-input multiple-output (MIMO) radiator is proposed. The proposed UWB-MIMO radiator was fabricated on FR-4 substrate material and measured. The isolation between every two adjacent ports was below −20 dB over the FCC-UWB spectrum and the Bluetooth band for the four MIMO antennas. The envelope correlation coefficient (ECC) between the proposed antennas in MIMO does not exceed 0.05. The diversity gains (DG) for all the radiators are greater than 9.98 dB.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Blockchain and machine learning (ML) has garnered growing interest as cutting-edge technologies that have witnessed tremendous strides in their respective domains. Blockchain technology provides a decentralized and immutable ledger, enabling secure and transparent transactions without intermediaries. Alternatively, ML is a sub-field of artificial intelligence (AI) that empowers systems to enhance their performance by learning from data. The integration of these data-driven paradigms holds the potential to reinforce data privacy and security, improve data analysis accuracy, and automate complex processes. The confluence of blockchain and ML has sparked increasing interest among scholars and researchers. Therefore, a bibliometric analysis is carried out to investigate the key focus areas, hotspots, potential prospects, and dynamical aspects of the field. This paper evaluates 700 manuscripts drawn from the Web of Science (WoS) core collection database, spanning from 2017 to 2022. The analysis is conducted using advanced bibliometric tools (e.g., Bibliometrix R, VOSviewer, and CiteSpace) to assess various aspects of the research area regarding publication productivity, influential articles, prolific authors, the productivity of academic countries and institutions, as well as the intellectual structure in terms of hot topics and emerging trends. The findings suggest that upcoming research should focus on blockchain technology, AI-powered 5G networks, industrial cyber-physical systems, IoT environments, and autonomous vehicles.

Universidad Internacional do Cuanza > Teaching > Final Degree Projects Abierto Inglés Power Quality (PQ) has become a significant issue in power networks. Power quality disturbances must be precisely and appropriately identified. This activity involves identifying, classifying, and mitigating power quality problems. A case study of the Awada industrial zone in Ethiopia is taken into consideration to show the practical applicability of the proposed work. It is found that the current harmonic distortion levels exceed the restrictions with a maximum percentage Total Harmonic Distortion of Current (THDI) value of up to 23.09%. The signal processing technique, i.e., Stockwell Transform (ST) is utilized for the identification of power quality issues, and it covers the most important and common power quality issues. The Support Vector Machine (SVM) method is used to categorize power quality issues, which enhances the classification procedure. The ST scored better in terms of accuracy than the Wavelet Transform (WT), Fourier Transform (FT), and Hilbert Transform (HT), obtaining 97.1%, as compared to 91.08%, 88.91%, and 86.8%, respectively. The maximum classification accuracy of SVM was 98.3%. To lower the current level of harmonic distortion in the industrial sector, a Distribution Static Compensator (D-STATCOM) is developed in the current control mode. To evaluate the performance of the D-STATCOM, the performance of the distribution network with and without D-STATCOM is simulated. The simulation results show that THDI is reduced to 4.36% when the suggested D-STATCOM is applied in the system.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés This study sought to investigate how different brain regions are affected by Alzheimer’s disease (AD) at various phases of the disease, using independent component analysis (ICA). The study examines six regions in the mild cognitive impairment (MCI) stage, four in the early stage of Alzheimer’s disease (AD), six in the moderate stage, and six in the severe stage. The precuneus, cuneus, middle frontal gyri, calcarine cortex, superior medial frontal gyri, and superior frontal gyri were the areas impacted at all phases. A general linear model (GLM) is used to extract the voxels of the previously mentioned regions. The resting fMRI data for 18 AD patients who had advanced from MCI to stage 3 of the disease were obtained from the ADNI public source database. The subjects include eight women and ten men. The voxel dataset is used to train and test ten machine learning algorithms to categorize the MCI, mild, moderate, and severe stages of Alzheimer’s disease. The accuracy, recall, precision, and F1 score were used as conventional scoring measures to evaluate the classification outcomes. AdaBoost fared better than the other algorithms and obtained a phenomenal accuracy of 98.61%, precision of 99.00%, and recall and F1 scores of 98.00% each.

Ibero-american International University > Research > Articles and Books Cerrado Inglés The Internet of Things (IoT) is a network of interconnected devices that includes low-end devices (sensors) and high-end devices (servers). The routing protocol used the Low-Power and Lossy Networks (RPL) protocol, which was designed to collect data in Low-Power and Lossy Networks (LLN) efficiently and reliably. The RPL rank property specifies how sensor nodes are placed in Destination Oriented Directed Acyclic Graphs (DODAG) based on an Objective Function (OF). The OF includes information such as the Expected Transmission Count (ETX) and packet delivery rate. The rank property aids in routing path optimization, reducing control overhead, and maintaining a loop-free topology by using rank-based data path validation. However, it causes many issues, such as optimal parent selection, next-hop node selection, and network instability. We proposed an Enhanced Opportunistic Rank-based Parent Node Selection for Sustainable and Smart IoT Networks to address these issues. The optimal parent node is determined by forecasting the expected energy of each node using Received Signal Strength (RSS) and an enhanced reinforcement learning algorithm. The proposed method addresses the issue of selecting the next-hop neighbor node and improves routing stability. Furthermore, when a large number of new nodes try to join the sustainable IoT-based smart cities, the proposed technique provides optimal load balance Chithaluru, Premkumar and Singh, Aman and Mahmoud, Mahmoud Shuker and Kumar, Sunil and Vidal Mazón, Juan Luis and Alkhayyat, Ahmed and Anand, Divya UNSPECIFIED, aman.singh@uneatlantico.es, UNSPECIFIED, UNSPECIFIED, juanluis.vidal@uneatlantico.es, UNSPECIFIED, divya.anand@uneatlantico.es

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Objective This study aims to develop a lightweight convolutional neural network-based edge federated learning architecture for COVID-19 detection using X-ray images, aiming to minimize computational cost, latency, and bandwidth requirements while preserving patient privacy. Method The proposed method uses an edge federated learning architecture to optimize task allocation and execution. Unlike in traditional edge networks where requests from fixed nodes are handled by nearby edge devices or remote clouds, the proposed model uses an intelligent broker within the federation to assess member edge cloudlets' parameters, such as resources and hop count, to make optimal decisions for task offloading. This approach enhances performance and privacy by placing tasks in closer proximity to the user. DenseNet is used for model training, with a depth of 60 and 357,482 parameters. This resource-aware distributed approach optimizes computing resource utilization within the edge-federated learning architecture. Results The experimental results demonstrate significant improvements in various performance metrics. The proposed method reduces training time by 53.1%, optimizes CPU and memory utilization by 17.5% and 33.6%, and maintains accurate COVID-19 detection capabilities without compromising the F1 score, demonstrating the efficiency and effectiveness of the lightweight convolutional neural network-based edge federated learning architecture. Conclusion Existing studies predominantly concentrate on either privacy and accuracy or load balancing and energy optimization, with limited emphasis on training time. The proposed approach offers a comprehensive performance-centric solution that simultaneously addresses privacy, load balancing, and energy optimization while reducing training time, providing a more holistic and balanced solution for optimal system performance.

In present investigation, the impact of nanoparticle concentration on the machining accomplishment of Hastelloy C-276 has been examined in turning operation. The outputs like temperature, surface roughness, chip reduction coefficient (CRC), tool wear, and friction coefficient along with angle of shear have been estimated. The graphene nanoparticles (GnP) have been blended into soybean oil in distinct weight/volume ratio of 0.5, 1 and 1.5%. The experimental observations revealed that higher concentration of nanoparticles has enhanced the heat carrying capacity of amalgamation by 12.28%, surface roughness (27.88%), Temperature (16.8%), tool wear (22.5%), CRC (17.5%), coefficient of friction (46.36%) and shear angle (15%). Scanning electron microscopy identified nose wear, abrasion, adhesion and loss of tool coating. Further, lower tool wear has been noticed at 1.5% concentration, while the complete failure of insert has been reported during 116 m/min, 0.246 mm/rev having 0.5% concentration. ANOVA results exhibited that surface roughness is highly influenced by speed rate (41.66%) trailed by feed rate (28.16%) and then after concentration (13.68%). Temperature is dominated by cutting speed (69.31%), concentration (14.53%) and feed rate (13.25%). Likewise, tool wear was majorly altered by cutting speed (67.2%) accompanied by feed rate (23.90%) and thirdly concentration of GnP (5.03%).

Tuberculosis (TB) is an airborne disease caused by Mycobacterium tuberculosis. It is imperative to detect cases of TB as early as possible because if left untreated, there is a 70% chance of a patient dying within 10 years. The necessity for supplementary tools has increased in mid to low-income countries due to the rise of automation in healthcare sectors. The already limited resources are being heavily allocated towards controlling other dangerous diseases. Modern digital radiography (DR) machines, used for screening chest X-rays of potential TB victims are very practical. Coupled with computer-aided detection (CAD) with the aid of artificial intelligence, radiologists working in this field can really help potential patients. In this study, progressive resizing is introduced for training models to perform automatic inference of TB using chest X-ray images. ImageNet fine-tuned Normalization-Free Networks (NFNets) are trained for classification and the Score-Cam algorithm is utilized to highlight the regions in the chest X-Rays for detailed inference on the diagnosis. The proposed method is engineered to provide accurate diagnostics for both binary and multiclass classification. The models trained with this method have achieved 96.91% accuracy, 99.38% AUC, 91.81% sensitivity, and 98.42% specificity on a multiclass classification dataset. Moreover, models have also achieved top-1 inference metrics of 96% accuracy and 98% AUC for binary classification. The results obtained demonstrate that the proposed method can be used as a secondary decision tool in a clinical setting for assisting radiologists.

Many researchers have already introduced behavior-aware protocols for a better understanding of architecture and realistic modeling of behavioral characteristics, similarities, and aggregation of mobile users. We are introducing the similarity analytical framework for the mobile encountering analysis to allow for more direct integration between the physical world and cyber-based systems. In this research, we propose a method for finding the similarity behavior of users’ mobility patterns based on location and time. This research was conducted to develop a technique for producing co-occurrence matrices of users based on their similar behaviors to determine their encounters. Our approach, named SAA (similarity analysis approach), makes use of the device info i.e., IP (internet protocol) and MAC (media access control) address, providing an in-depth analysis of similarity behaviors on a daily basis. We analyzed the similarity distributions of users on different days of the week for different locations based on their real movements. The results show similar characteristics of users with common mobility behaviors based on location and time to showcase the efficacy. The results show that the proposed SAA approach is 33% more accurate in terms of recognizing the user’s similarity as compared to the existing similarity approach.

Consequently, the impact analysis of innovation on the performance of an organization holds great importance. This paper presents a two-stage analytical framework to examine the impact of business innovation on a firm’s performance, especially firms from the manufacturing sector. The prime objective is to identify the factors that have an impact on firm-level innovation, and to examine the impact of firm-level innovation on business performance. The framework and its analysis are based on the latest World Bank enterprise survey, with a sample size of 696 manufacturing firms. The first stage of the proposed framework establishes the analytical results through Bivariate Probit, which indicates that research and development (R&D) has a significantly positive impact on the product, process, marketing, and organizational innovations. It thus highlights the important role of the allocation of lump-sum amounts for R&D activities. The statistical analysis shows that innovation does not depend on the size of the firms. Moreover, the older firms are found to be wiser at conducting R&D than newer firms that are reluctant to take risks. The second stage of the proposed framework separately analyzes the impacts of the product and organizational innovation, and the process and marketing innovation on the firm performance, and finds them to be statistically significant and insignificant, respectively.

The virus spreads from people, contaminated places, and nozzle droplets that necessitate strict precautionary measures. Consequently, different safety precautions have been implemented to fight COVID-19 such as wearing a facemask, restriction of social gatherings, keeping 6 feet distance, etc. Despite the warnings, highlighted need for such measures, and the increasing severity of the pandemic situation, the expected number of people adopting these precautions is low. This study aims at assessing and understanding the public perception of COVID-19 safety precautions, especially the use of facemask. A unified framework of sentiment lexicon with the proposed ensemble EB-DT is devised to analyze sentiments regarding safety precautions. Extensive experiments are performed with a large dataset collected from Twitter. In addition, the factors leading to a negative perception of safety precautions are analyzed by performing topic analysis using the Latent Dirichlet allocation algorithm. The experimental results reveal that 12% of the tweets correspond to negative sentiments towards facemask precaution mainly by its discomfort. Analysis of change in peoples’ sentiment over time indicates a gradual increase in the positive sentiments regarding COVID-19 restrictions.

The location prediction of mineral reservoirs like oil, gas, or metals in deep water is a challenge during the extraction of these resources. Moreover, the problem of ores and mineral deposits on the seafloor comes into play. The abovementioned challenges necessitate for the deployment of underwater wireless sensor networks (UWSNs). Anchor-based localization techniques are segregated into range-free and range-based processes. Range-based schemes depend on various techniques like angle of arrival (AoA), time of arrival (ToA), time difference of arrival (TDoA), and received signal strength indicator (RSSI). In this article, the localization of these leakages is performed by using range-based metrics for calculating the distance among anchor nodes (ANs) and target nodes (TNs). This estimated distance is further optimized to minimize the estimation error. A multilateralism procedure is used to estimate the optimal position of each TN. The results exhibit that the proposed algorithm shows a high performance when compared to previous works, in terms of minimum energy consumption, lower packet loss, rapid location estimation, and lowest localization error. The benefit of using the proposed methodology greatly impacts on identifying the leakage area in mobility-assisted UWSN, where rapid reporting helps to lower the loss of resources.

Fog computing can resolve these issues to some extent, yet it is still in its infancy. Despite several existing works, these works lack fault-tolerant fog computing, which necessitates further research. Fault tolerance enables the performing and provisioning of services despite failures and maintains anti-fragility and resiliency. Fog computing is highly diverse in terms of failures as compared to cloud computing and requires wide research and investigation. From this perspective, this study primarily focuses on the provision of uninterrupted services through fog computing. A framework has been designed to provide uninterrupted services while maintaining resiliency. The geographical information system (GIS) services have been deployed as a test bed which requires high computation, requires intensive resources in terms of CPU and memory, and requires low latency. Keeping different types of failures at different levels and their impacts on service failure and greater response time in mind, the framework was made anti-fragile and resilient at different levels.

Por otro lado, se conoce que las sales minerales tienen precios elevados en el mercado, por lo que los pequeños ganaderos han optado por suministrar sal corriente a los bovinos, lo cual actualmente es solo un costo, porque nutricionalmente no se está haciendo ningún aporte a los animales, por lo que se ha decido, crear una empresa productora de sales minerales de alta calidad para bovinos, amigable con el medio ambiente, de origen mineral y a un costo que permita a los pequeños ganaderos la compra de la misma, buscando la rentabilidad y productividad de los ellos. Considerando lo antes mencionado, se realiza un análisis de mercado e indicadores técnico-financieros que permitieron determinar la viabilidad para la creación de una empresa productora de sales minerales para ganadería, porque no solo se buscó apoyar el sector ganadero, sino también buscar puntos de equilibrio que permitieran la creación y la sostenibilidad de la compañía emergente.Una vez realizado el análisis técnico-financiero, apoyado del estudio de mercado y todo el marco legal y nutricional relacionado con empresas productoras de sales minerales para bovinos, se ha encontrado que la compañía es rentable, basándose en los resultados obtenidos para cada uno delos indicadores financieros como VAN, TIR y B/C y con una recuperación estimada de capital en 2 año, aunque la proyección inicial es de 3 años.Debido a que la rentabilidad y productividad de la ganadería depende de los suplementos y alimentación de los animales, el mercado ganadero respecto a las sales se vuelve de gran importancia e innovador, por lo que después de crear esta compañía y empezar producciones con gran aceptabilidad por los clientes se concluye que la compañía tiene prospección de viabilidad y sostenibilidad en el tiempo, sin embargo, existen factores externos que pueden afectar el funcionamiento normal de la empresa, tal y como los tiempos de respuesta de los entes gubernamentales, tiempos de entrega de resultados por parte de los laboratorios analíticos, los que afectan la rotación del producto terminado, incremento de precios debido a problemáticas sociales que se relaciona directamente con el transporte de las mismas. Los factores externos antes mencionados, pueden son tenidos en cuenta en las programaciones con el fin de mitigar el impacto de los mismos en el funcionamiento de la empresa.

El agua es un recurso natural indispensable para el desarrollo múltiples actividades de la praxis cotidiana, no obstante, su uso está limitado por su calidad. Por consiguiente, resulta imprescindible analizar las condiciones específicas de cada cuerpo hídrico, para poder determinan los posibles usos que se le puedan dar y del mismo modo definir los impactos que puede ocasionar sobre la salud humana y el medio ambiente. Esta investigación se centra en analizar la calidad del agua de la quebrada Manizales, uno de los principales afluentes hídricos de la ciudad de Manizales (Colombia), sobre la cual se vierten aguas residuales domésticas y no domésticas. Y, tiene como objetivo principal analizar las alteraciones fisicoquímicas que se generan por los vertimientos industriales. Para ello se emplea una metodología de investigación cuasi experimental, mediante la toma de muestras en dos puntos de monitoreo aguas arriba y aguas abajo del parque industrial Juanchito, durante dos semanas, en horarios diurnos y nocturnos. Obteniendo como resultado el reporte de metales pesados como el Mercurio y el Plomo en concentraciones de 0,00951 mg/L y 0,14 mg/L, respectivamente. Valores que exceden los límites de referencia permisibles por la normatividad ambiental colombiana y que pueden llegar a ser perjudiciales para la salud humana.

La delegación es una forma legítima que tienen los Estados centralizados o seccionales de transferir capacidades jurídicas, administrativas, operacionales y de gestión en general a entidades descentralizadas del propio Estado o entes del sector privado. En el Ecuador existen varias formas de delegar competencias y gestiones financieras, administrativas y operativas a cargo de empresas estatales extranjeras, privadas nacionales o extranjeras e incluso por medio de alianzas público-privadas. Los puertos marítimos del Ecuador forman parte de los sectores estratégicos del Estado por sus condiciones de infraestructura, ubicación geopolítica y facilidades de conectividad, elementos que los hacen atractivos para los inversionistas nacionales e internacionales especializados en los negocios marítimos, situación que los transforma en aliados valiosos para el comercio internacional y el tránsito de pasajeros turísticos. La estructura jurídica fundamental que soporta la acción de concesionar o delegar áreas de sectores estratégicos del Estado ecuatoriano —en este caso los puertos marítimos— tiene sustento legal en la Constitución de la República, el Código Orgánico de la Producción Comercio e Inversiones, la Ley Orgánica de Incentivos Para Asociaciones Público Privadas, el Código Orgánico Administrativo y Ley Orgánica de la Contraloría General del Estado, entre otros cuerpos legales. El objetivo fundamental para la delegación e incluso la concesión de los puertos marítimos en el Ecuador obedece a la búsqueda de una gestión eficiente y eficaz para crear un entorno competitivo, sostenido en un ordenamiento jurídico que le permite lograr una dinámica efectiva que incentiva el comercio multilateral. El Estado ecuatoriano pretende que las ventajas comparativas y competitivas de infraestructuras y posicionamiento estratégico sirvan para generar un desarrollo sostenido basado en la capacidad de brindar servicios portuarios ágiles, seguros y con costes competitivos.

Varias organizaciones y profesionales de la gestión de proyectos centran su atención en el desempeño en la realización de proyectos. Durante varios años, Camerún se ha dedicado a la realización de grandes proyectos de construcción potencialmente comparables a megaproyectos, como el proyecto de construcción del segundo puente sobre el Wouri. El objetivo general de este estudio fue analizar el nivel de desempeño del proyecto para construir el segundo puente sobre el Wouri. Esta investigación se desarrolló a partir de un enfoque cualitativo por un lado y un enfoque cuantitativo por el otro. Esta investigación eligió la entrevista semiestructurada a través de un cuestionario y la investigación documental como instrumentos de recolección de datos. Los participantes estaban compuestos por un representante de la autoridad contratante, un representante del propietario del proyecto, un representante del jefe del servicio contratado, un representante del ingeniero contratado, un representante del asistente del propietario del proyecto y dos representantes de la empresa que realiza el trabajo. Los datos recopilados se analizaron utilizando el software de análisis de datos Statistical Package for the Social Sciences (SPSS) y el software EXCEL. Parece que no se cumplieron los plazos y costes de ejecución, pero se cumplió el nivel de calidad inicialmente previsto. Los resultados de esta investigación son similares a los hallazgos de OPS (2011), Standish group (2018) y PMI (2015) en cuanto a investigaciones sobre el desempeño de proyectos con alto porcentaje de fallas en megaproyectos.

Recientemente la investigación en secadores solares se enfoca en determinar la cinética de secado y su descripción a partir de modelos matemáticos, sin embargo, los estudios exergéticos son relativamente limitados. Se requieren estudios teóricos y experimentales para romper la barrera del conocimiento con este enfoque, que permitan evaluar el máximo potencial de trabajo útil desperdiciado por un sistema (pérdida de exergía) a medida que se equilibra con un entorno de referencia (medio ambiente). Este trabajo presenta, mediante la instrumentación de secadores solares tipo gabinete, el modelado matemático y análisis exergético, para evaluar los procesos de transferencia de calor y masa del secado de soya en climas cálidos-húmedos, específicamente en la ciudad de San Francisco de Campeche, Campeche. El paradigma de investigación es cuantitativo puesto que se recolectaron datos para probar una hipótesis con base en la medición numérica y análisis estadístico, con el fin de establecer pautas de comportamiento. Se analizó el comportamiento de la irradiancia, temperatura ambiente y humedad relativa y su relación con la pérdida de peso. Se comparó el desempeño térmico de secadores solares directos (tipo gabinete) con convección natural y convección forzada con un horno convencional eléctrico a temperaturas controladas (55 °C y 65 °C). Se obtuvieron datos de contenido de humedad para realizar la cinética de secado y evaluar los modelos matemáticos propuestos. De igual manera, se realizó un análisis de colorimetría para estudiar el efecto del secado sobre las características visuales del producto. Las eficiencias exergéticas promedio fueron 47.40 % y 53.67 % para la convección natural y convección forzada, respectivamente. Se estimaron los indicadores de sustentabilidad exergética como son: potencial de mejora, índice de sustentabilidad y relación de energía residual.

Ibero-american International University > Teaching > Master's Final Projects Cerrado Español La empresa constructora CONSTRUCOR&BAI S.A. empieza sus operaciones el 28 de julio del 2017, es una empresa cuya actividad está orientada al sector de la construcción. Al ser una pyme, está en un sector bastante competitivo y por tener pocos años de existencia en el mercado, se ha evidenciado la falta de estrategias que le permitan administrar de manera eficiente cada una de las áreas que conforman la organización. Una de las herramientas que dan orientación a las empresas para la consecución de sus objetivos en todas sus áreas, está el Cuadro de Mando Integral (CMI), el cual consiste en un conjunto de indicadores que brindan a los ejecutivos de las organizaciones una visión comprensiva del negocio. El objetivo general del presente trabajo de investigación está en desarrollar un proyecto de Cuadro de Mando Integral en la empresa CONSTRUCOR&BAI S.A., en las áreas financiera, atención a clientes, aprendizaje y procesos internos. La metodología aplicada fue de enfoque cuali-cuantitativo, aplicando como instrumento de recolección de datos la encuesta y la entrevista. En cada una de ellas, se aplicó como instrumento el cuestionario, el cual consta de 27 preguntas de tipo cerrado para empleados y 21 preguntas para clientes, referentes a aspectos fundamentales del CMI. En cuanto a la entrevista, se la aplicó para los directivos de la empresa CONSTRUCOR&BAI S.A., con un cuestionario de 10 preguntas abiertas, quienes tuvieron la oportunidad de dar su opinión referente a la temática investigativa para su respectivo análisis. La muestra seleccionada constó de 8 empleados, entre los cuales están 2 funcionarios de mandos altos y 6 empleados de mando bajo dentro de la empresa, al igual que se seleccionaron los 20 clientes que cuenta la empresa. Dentro de los resultados hallados, se evidenció el profesionalismo que existe en los empleados, lo cual implica que la empresa cuenta con un personal preparado para las funciones designadas. En lo que respecta a los puntos débiles, se evidencia la falta de un plan estratégico para administrar de forma eficiente cada uno de los planes y proyectos contratados. Otro de los aspectos a tomar en cuenta, están los equipos y maquinarias que no están modernizados para el desarrollo de las obras, y existen atrasos en los tiempos de entrega. Como parte de la propuesta, se establecieron 6 pasos fundamentales para lograr el éxito esperado. Se concluye que, con la implementación del CMI ayudará a la gerencia a la identificación de los procesos decisivos en generar valor agregado a la empresa.

En la industria Petrolera de la República Argentina, los suelos que resultan del producto de la limpieza de tanques o saneamiento de derrames de petróleos pesados, generan un problema de gran impacto en materia ambiental y de productividad. Desde el punto de vista ambiental, durante la limpieza de estos eventos se generan grandes volúmenes de residuos que se acopian transitoriamente en piletas “a cielo abierto”. En cuanto al aspecto productivo, la presencia de estos sedimentos en los tanques resta capacidad de almacenar y producir petróleo. El presente proyecto constó de varias etapas: las cuales se pueden enmarcar en estudios preliminares, de tratamiento propiamente dicho y posterior análisis de viabilidad económica. El primer paso constó de un análisis del caso de estudio, para el cual se seleccionó un volumen de suelos con hidrocarburos acopiados en sitios destinados para acopios transitorios y su posterior tratamiento. El trabajo fue diseñado tomando una porción de 800 m3 de suelos afectados por hidrocarburos, los cuales fueron muestreados con fines de realizar el estudio de viabilidad técnica realizando un ensayo de biodegradabilidad. El mismo demandó 15 días de ensayos en laboratorios dando por resultado que el suelo seleccionado es tratable bajo la metodología de Biorremediación bajo la técnica de biopilas aireadas mecánicamente. Estos ensayos se realizaron con los laboratorios de la Facultad de Ingeniería de la Universidad Nacional de Cuyo. Posteriormente procedimos al acondicionamiento del suelo y al armado de la biopila, el acondicionamiento constó del agregado de nutrientes de forma que alcanzara para una biodegradación mensual del 35 al 30%, luego se realizó la humectación del suelo alcanzando la humedad deseada para este tipo de tratamientos. Posteriormente se realizó armado de la biopila para dar inicio al tratamiento propiamente dicho. En cuanto a las concentraciones de hidrocarburos en suelo iniciaron con una concentración que rondó el 10% (100.000 ppm), esta concentración llegó hasta el 12%. A partir de esta concentración la curva de los hidrocarburos fue decayendo hasta llegar al objetivo de limpieza que es el 1% o 10.000 ppm. Este proceso demandó 18 meses de trabajo, pero se cumplió con la meta de limpieza. Posteriormente se realizó la evaluación económica del trabajo final, el cual se basó en comparar los tiempos de tratamiento del mismo volumen de suelo bajo la técnica de biorremediación con la técnica de incineración de residuos. El resultado final de este estudio indica que transportar e incinerar este volumen de suelo demandaría unos 12 meses vs los 18 meses de tratamiento bajo la metodología del proyecto. Luego se procedió a realizar el análisis de los costos de ambas tecnologías el cual por lógica la incineración es 10 veces más costosa que la biorremediación de suelos. En conclusión, se puede decir que la biorremediación de suelos mediante la técnica de biopilas aireadas mecánicamente es aplicable para resolución los suelos afectados por hidrocarburos de alto peso molecular.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español En el presente proyecto se han utilizado técnicas, herramientas y metodologías de la administración y gestión de operaciones, las cuales nos ayudaron a mejorar los balances para asignar eficientemente los recursos en las series TCSD y FFSD en el área de IDC Samtec CR. Para esto, se plantearon objetivos que fueran razonablemente alcanzables y que pudieran definir la ruta de trabajo de una forma ordenada y sistema. Es por ello, que el estudio inició con entender la distribución del proceso y su layout, el cómo estaba conformada la secuencia de operaciones en cada una de las etapas de fabricación y no menos importante, en analizar el flujo de proceso a través de toda la cadena de valor y determinar cuáles eran las debilidades del área. Samtec es una empresa multinacional desarrollada en la industria electrónica y ha tenido un crecimiento importante durante el año 2021 y lo que lleva del 2022, pero sin un estudio detallado que le ayude a determinar cuál es verdaderamente su capacidad instalada y como debe de gestionar sus recursos en los diferentes procesos. También, se crean herramientas de cálculo numérico para que el administrador tenga un panorama general de cuando, donde y como asignar los insumos disponibles dentro del área IDC. Estos métodos integran acciones para la toma de decisiones y así comprender en el corto plazo cuales son las necesidades inmediatas para lograr cumplir con los pedidos del cliente de una forma planeada, organizada y controlada. Para esto fue requerido un estudio de tiempos, la actualización de la cantidad de unidades producidas por hora, conocer la cantidad de personal necesario dentro de la línea de producción, la maquinaria, herramienta y equipo que se tiene en cada una de las estaciones de trabajo entre otros insumos importantes dentro del análisis. Por otro lado, al tener un mejor uso y manejo eficiente de los recursos, el aporte dentro de los indicadores de calidad, productividad, entrega de órdenes a tiempo y scrap será notorio en el tiempo dentro del área. Hoy en día la responsabilidad de la eficiencia y los resultados están posicionados en los administradores y dueños de los procesos y este proyecto abre esa visión de gestión.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Population and industrial growth in Mexico’s Bajío region demand greater electricity consumption. The production of electricity from fuel oil has severe implications on climate change and people’s health due to SO2 emissions. This study describes the simulation of eight different scenarios for SO2 pollutant dispersion. It takes into account distance, geoenvironmental parameters, wind, terrain roughness, and Pasquill–Gifford–Turner atmospheric stability and categories of dispersion based on technical information about SO2 concentration from stacks and from one of the atmospheric monitoring stations in Salamanca city. Its transverse character, its usefulness for modeling, and epidemiological, meteorological, and fluid dynamics studies, as suggested by the models approved by the Environmental Protection Agency (EPA), show a maximum average concentration of 399 µg/m3, at an average distance of 1800 m. The best result comparison in the scenarios was scenery 8. Maximum nocturnal dispersion was shown at a wind speed of 8.4 m/s, and an SO2 concentration of 280 µg/m3 for stack 4, an atypical situation due to the geography of the city. From the validation process, a relative error of 14.7 % was obtained, which indicates the reliability of the applied Gaussian model. Regarding the mathematical solution of the model, this represents a reliable and low-cost tool that can help improve air quality management, the location or relocation of atmospheric monitoring stations, and migration from the use of fossil fuels to environmentally friendly fuels.

So, water quality prediction, an essential element for a healthy society, has become a task of great significance to protecting the water environment. Existing approaches focus predominantly on either water quality or water consumption prediction, utilizing complex algorithms that reduce the accuracy of imbalanced datasets and increase computational complexity. This study proposes a simple architecture of neural networks which is more efficient and accurate and can work for predicting both water quality and water consumption. An artificial neural network (ANN) consisting of one hidden layer and a couple of dropout and activation layers is utilized in this regard.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Building energy consumption prediction has become an important research problem within the context of sustainable homes and smart cities. Data-driven approaches have been regarded as the most suitable for integration into smart houses. With the wide deployment of IoT sensors, the data generated from these sensors can be used for modeling and forecasting energy consumption patterns. Existing studies lag in prediction accuracy and various attributes of buildings are not very well studied. This study follows a data-driven approach in this regard. The novelty of the paper lies in the fact that an ensemble model is proposed, which provides higher performance regarding cooling and heating load prediction. Moreover, the influence of different features on heating and cooling load is investigated. Experiments are performed by considering different features such as glazing area, orientation, height, relative compactness, roof area, surface area, and wall area. Results indicate that relative compactness, surface area, and wall area play a significant role in selecting the appropriate cooling and heating load for a building. The proposed model achieves 0.999 R2 for heating load prediction and 0.997 R2 for cooling load prediction, which is superior to existing state-of-the-art models. The precise prediction of heating and cooling load, can help engineers design energy-efficient buildings, especially in the context of future smart homes Chaganti, Rajasekhar and Rustam, Furqan and Daghriri, Talal and Díez, Isabel de la Torre and Vidal Mazón, Juan Luis and Rodríguez Velasco, Carmen Lilí and Ashraf, Imran UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, juanluis.vidal@uneatlantico.es, carmen.rodriguez@uneatlantico.es, UNSPECIFIED

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Developments in medical care have inspired wide interest in the current decade, especially to their services to individuals living prolonged and healthier lives. Alzheimer’s disease (AD) is the most chronic neurodegeneration and dementia-causing disorder. Economic expense of treating AD patients is expected to grow. The requirement of developing a computer-aided technique for early AD categorization becomes even more essential. Deep learning (DL) models offer numerous benefits against machine learning tools. Several latest experiments that exploited brain magnetic resonance imaging (MRI) scans and convolutional neural networks (CNN) for AD classification showed promising conclusions. CNN’s receptive field aids in the extraction of main recognizable features from these MRI scans. In order to increase classification accuracy, a new adaptive model based on CNN and support vector machines (SVM) is presented in the research, combining both the CNN’s capabilities in feature extraction and SVM in classification. The objective of this research is to build a hybrid CNN-SVM model for classifying AD using the MRI ADNI dataset. Experimental results reveal that the hybrid CNN-SVM model outperforms the CNN model alone, with relative improvements of 3.4%, 1.09%, 0.85%, and 2.82% on the testing dataset for AD vs. cognitive normal (CN), CN vs. mild cognitive impairment (MCI), AD vs. MCI, and CN vs. MCI vs. AD, respectively. Finally, the proposed approach has been further experimented on OASIS dataset leading to accuracy of 86.2%.

El sistema de inteligencia competitiva (SIC) es una disciplina emergente que está provocando un creciente interés y se han convertido en una herramienta clave para el éxito en la toma de decisiones de las empresas pero, al no conocerla o utilizarla, ponen en grave riesgo la supervivencia de las empresas (Ezquer & Castellano, 2010). El objetivo de la investigación es determinar el patrón que siguen las organizaciones en los ciclos de inteligencia, contrainteligencia y modelos organizacionales como estrategias de mejora para la toma de decisiones en el SIC de las empresas. La metodología estuvo basada en el diseño de investigación documental con la utilización de un registro de codificación y un instrumento o tabla para el análisis de contenido cualitativo sobre una muestra de 60 documentos producidos durante los años 2015 -2020.En el resultado se determinó el patrón de los ciclos de inteligencia, contrainteligencia y modelos organizacionales durante los años 2015-2020. En el ciclo de inteligencia fueron: planificación / planificar, colección / colectar, análisis / analizar y difusión / difundir. En el ciclo de contrainteligencia fueron: planificación / planificar, recopilación, análisis y difusión; durante los años 2019-2020 no se consiguieron resultados. Y, en el modelo organizacional fueron unidad y consultoría. En la conclusión se determinó que los SIC en las organizaciones pueden ser abordados vinculando herramientas como la inteligencia y la contrainteligencia adaptándolas al modelo de la organización, y con ello generar ventajas competitivas para la toma de decisiones en las organizaciones. Además, se consiguió corroborar que existen deficiencias en los ciclos de contrainteligencia durante los años 2019-2020 y que es el menos comprendido frente al desarrollo estructural de lo que es inteligencia.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español En la investigación cientifica sobre la Clasificación de riesgos en el manejo y transporte de cargas para la prevención de los problemas osteomusculares en los trabajadores de exportadora de cacao Verapaz, un tema relacionado al trabajo que realizan hombre y mujeres en la comercialización del cacao de cuatro comunidades del departamento de Alta Verapaz.La exportadora de Cacao Verapaz es la organización que dirige la producción y comercialización del cacao en Alta Verapaz, Guatemala. El objetivo general de la investigación es desarrollar un programa para la clasificación de riesgos en el manejo y transporte de cargas para la aplicación de procedimientos técnicos y operativos que eviten la aparición de problemas osteomusculares en los trabajadores de la exportadora de cacao Verapaz, dándole enfoque preventivo y para buscar oportunidades de mejora en el área de la prevencion de riesgos, por lo que se toman los objetivos específicos de: Identificar las tareas que tienen riesgo extremadamente alto, alto y moderado en el manejo de cargas para los trabajadores, así como clasificar el nivel de riesgo en el manejo de cargas, para posteriormente desarrollar un programa para el control de riesgos de trabajadores clasificados en el nivel de riesgo extremadamente alto, alto y moderado y al mismo tiempo proponer medidas de prevención, sustitución y eliminación de riesgos que implican desarrollar problemas osteomusculares. Para dicha investigación se utiliza una metodología cuantitativa con un diseño de Investigación Descriptivo. Se tiene un universo de 930 trabajadores de sexo masculino y femenino de las regiones de Cahabón, La Chúa, San Juan Chivite, y la finca Chimelb todos de Alta Verapaz y se toma una muestra por conveniencia no probabilística de 25 trabajadores, con los criterio de inclusión a) sexo masculino, b) edad de 18 a 40 años, c) trabajadores de selección manual del cacao d) trabajador encargado del volteo del cacao en caja de fermentación d) trabajadores encargados de transporte del cacao hacia el secado en el sol e) trabajadores que trasportan y apilan la carga en bodega de forma manual se aplican criterios de exclusión tales como a) trabajadores vacacionistas. b) trabajadores que no tienen horario de trabajo establecido c) trabajadores con menos de un año de trabajo en manejo de cargas d) trabajadores que trasportan las cargas en grupos e) trabajadores que refieran enfermedades preexistentes. Para la realización de la investigación se utiliza como técnica de recolección de datos la herramienta de inspección MAC (Manual Handling Assessment Charts) desarrollada por la Dirección de Salud y Seguridad en Inglaterra. Health and Safety Executive, UK. (2003). Técnica que utiliza una escala cuantitativa para medir el riesgo y un código de colores para calificar cada factor. La inspección se realiza a trabajadores que realizan las tareas de levantamiento, descenso y transporte individual de la carga, durante un periodo de ocho horas por una semana, identificando factores ambientales.Los resultados más importantes que se tienen son primer resultado manejo, descenso y trasporte de cargas con un peso superior al establecido en Acuerdo Gubernativo 29-2014 de Guatemala, un segundo resultado importante es una mala distancia entre los brazos y el cuerpo al levantar, defender y transportar la carga, otro resultado importante es un mal acoplamiento mano objeto debido a una mala técnica y a herramientas que no poseen una forma adecuada de sujeción, así mismo el transporte de la carga de forma manual y con peso superior al establecido coloca este tarea como un riesgo extremadamente alto al subir el peso por sobre la cabeza y transportarlo a una distancia superior a diez metros. Como oportunidad de mejora inmediata se plantea un programa de prevención con principios de Biomecánica, mecanización del peso permitido, selección/uso adecuado de las herramientas manuales y el análisis para la mitigación de los riesgos no tolerados por medio de medidas administrativa y organización de tareas en el trabajo. La estrategia a utilizar es el entrenamiento a los trabajadores en un periodo de seis meses y posteriormente evaluar las tareas con reducción de riesgos por medio de los indicadores:•Reducción del peso de la carga mínimo a 45 kilogramos para hombres mayores de 22 años en adelante.•80 % de trabajadores no inclinan la espalda y mantiene una postura ergonómica correcta.•100 % de trabajadores colocan los brazo pegados al cuerpo para hacer la fuerza física.•El 100% de los trabajadores que recolectan cacao hacen giros no mayores a 30 grados, evitando lateralización de tronco.•El 100 % de los trabajadores aplica la técnica correcta para el manejo de la carga.

Subjects > Engineering Ibero-american International University > Research > Articles and books Cerrado Inglés According to the World Health Organization (WHO), Parkinson’s disease (PD) is a neurodegenerative disease of the brain that causes motor symptoms including slower movement, rigidity, tremor, and imbalance in addition to other problems like Alzheimer’s disease (AD), psychiatric problems, insomnia, anxiety, and sensory abnormalities. Techniques including artificial intelligence (AI), machine learning (ML), and deep learning (DL) have been established for the classification of PD and normal controls (NC) with similar therapeutic appearances in order to address these problems and improve the diagnostic procedure for PD. In this article, we examine a literature survey of research articles published up to September 2022 in order to present an in-depth analysis of the use of datasets, various modalities, experimental setups, and architectures that have been applied in the diagnosis of subjective disease. This analysis includes a total of 217 research publications with a list of the various datasets, methodologies, and features. These findings suggest that ML/DL methods and novel biomarkers hold promising results for application in medical decision-making, leading to a more methodical and thorough detection of PD. Finally, we highlight the challenges and provide appropriate recommendations on selecting approaches that might be used for subgrouping and connection analysis with structural magnetic resonance imaging (sMRI), DaTSCAN, and single-photon emission computerized tomography (SPECT) data for future Parkinson’s research.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Asthma is a deadly disease that affects the lungs and air supply of the human body. Coronavirus and its variants also affect the airways of the lungs. Asthma patients approach hospitals mostly in a critical condition and require emergency treatment, which creates a burden on health institutions during pandemics. The similar symptoms of asthma and coronavirus create confusion for health workers during patient handling and treatment of disease. The unavailability of patient history to physicians causes complications in proper diagnostics and treatments. Many asthma patient deaths have been reported especially during pandemics, which necessitates an efficient framework for asthma patients. In this article, we have proposed a blockchain consortium healthcare framework for asthma patients. The proposed framework helps in managing asthma healthcare units, coronavirus patient records and vaccination centers, insurance companies, and government agencies, which are connected through the secure blockchain network. The proposed framework increases data security and scalability as it stores encrypted patient data on the Interplanetary File System (IPFS) and keeps data hash values on the blockchain. The patient data are traceable and accessible to physicians and stakeholders, which helps in accurate diagnostics, timely treatment, and the management of patients. The smart contract ensures the execution of all business rules. The patient profile generation mechanism is also discussed. The experiment results revealed that the proposed framework has better transaction throughput, query delay, and security than existing solutions Farooq, Muhammad Shoaib and Suhail, Maryam and Qureshi, Junaid Nasir and Rustam, Furqan and de la Torre Díez, Isabel and Vidal Mazón, Juan Luis and Rodríguez Velasco, Carmen Lilí and Ashraf, Imran UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, juanluis.vidal@uneatlantico.es, carmen.rodriguez@uneatlantico.es, UNSPECIFIED

Asthma patients approach hospitals mostly in a critical condition and require emergency treatment, which creates a burden on health institutions during pandemics. The similar symptoms of asthma and coronavirus create confusion for health workers during patient handling and treatment of disease. The unavailability of patient history to physicians causes complications in proper diagnostics and treatments. Many asthma patient deaths have been reported especially during pandemics, which necessitates an efficient framework for asthma patients. In this article, we have proposed a blockchain consortium healthcare framework for asthma patients. The proposed framework helps in managing asthma healthcare units, coronavirus patient records and vaccination centers, insurance companies, and government agencies, which are connected through the secure blockchain network. The proposed framework increases data security and scalability as it stores encrypted patient data on the Interplanetary File System (IPFS) and keeps data hash values on the blockchain. The patient data are traceable and accessible to physicians and stakeholders, which helps in accurate diagnostics, timely treatment, and the management of patients. The smart contract ensures the execution of all business rules. The patient profile generation mechanism is also discussed. The experiment results revealed that the proposed framework has better transaction throughput, query delay, and security than existing solutions Farooq, Muhammad Shoaib and Suhail, Maryam and Qureshi, Junaid Nasir and Rustam, Furqan and de la Torre Díez, Isabel and Vidal Mazón, Juan Luis and Rodríguez Velasco, Carmen Lilí and Ashraf, Imran UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, juanluis.vidal@uneatlantico.es, carmen.rodriguez@uneatlantico.es, UNSPECIFIED

En México por cientos de años los sitios de disposición de relaves con metales pesados (MPs), están presentes en las regiones áridas y semiáridas. A finales del siglo pasado y en la actualidad, la producción de desechos mineros se ha incrementado considerablemente y su dispersión ocasiona problemas a la salud humana y el medio ambiente. No obstante, en estos sitios existen plantas silvestres adaptadas para sobrevivir y reproducirse en suelos altamente contaminados, con potencial para fitorremediación. Dos jales de una mina localizada en Sombrerete, Zac. fue inspeccionada para identificar especies de plantas que basado en la concentración acumulada en los brotes de arsénico y plomo y su factor de bioconcentración, sean favorables para fitorremediación. El plan de muestreo se desarrolló conforme a la norma oficial mexicana: NMX-AA-132-SCFI-2006. El análisis del contenido de As y Pb se realizó de acuerdo a la NOM-147-SEMARNAT/SSA1-2004, mediante Espectrometría de Absorción Atómica. La flora asociada está conformada por 9 especies agrupadas en 5 familias. La familia mejor representada fue Asteraceae. Respecto a las concentraciones de las plantas, estas acumulan MPs superiores a los niveles de fitotoxicidad comúnmente aceptados, y pueden ser favorables para el establecimiento de una cubierta vegetal sobre otros jales en la región de Sombrerete. Las plantas silvestres que mostraron valores máximos de arsénico en sus brotes, fueron Asphodelus fistulosus (447 mg/kg), Pennisetum villosum (342 mg/kg) y Purshia mexicana (268 mg/kg). Por consiguiente, según el factor de bioconcentración ninguna de las especies mostró concentraciones de metales en los brotes por arriba del criterio del contenido de una hiperacumuladora,. Mientras que las concentraciones para plomo, en todas las plantas fueron muy bajas. De acuerdo a los procesos de recuperación de los metales, el tiempo que tienen los residuos mineros, las condiciones específicas y las concentraciones de As y PB en el substrato rizosférico de los jales, así como la tolerancia y los procesos de adaptación al ambiente extremo; la mayoría de las especies de arbustos de matorral xerófilo tienen comportamiento de excluidoras y con potencial aplicación de fitoestabilizadoras de As en las regiones áridas y semiáridas.

Generando especial interés en el estudio de medidas de adaptación que eviten establecer prácticas erróneas, debido a que sus efectos podrán ser más contraproducentes que los beneficios generados (Naciones Unidas 2017). El presente estudio evalúa el efecto de la aplicación de riego el cultivo de palma de aceite como medida adaptativa al cambio climático por medio de la utilización de modelos de simulación de producción agrícola calibrados para condiciones del Pacifico Central de Costa Rica.Para poder realizar lo planteado, se realizó un análisis clúster sobre el conjunto de unidad de producción, permitiendo identificar un grupo de lotes de trabajo representativos. Sobre este grupo se generaron simulaciones de sistemas de producción calibradas en el software APSIM. En estos modelos calibrados se corrieron tres escenarios; una Línea base para el periodo 2000-2019, un escenario de cambio climático para mediados de siglo del 2040 al 2059 (ECC1) y otro para finales de siglo del 2080 al 2099 (ECC2). La comparación de las corridas de Línea base contra ECC1 y ECC2 permitió cuantificar los efectos del cambio climático sobre el rendimiento del cultivo de palma de aceite. Finalmente, en las simulaciones los ECC 1 y 2 se aplicó irrigación como medida adaptativa. Determinando los valores de agua disponible en el suelo que mantenga los rendimientos generados en la Línea base.Se establece que para el ECC1 se tendrá una disminución de las lluvias acumuladas anuales del 5.55% y un aumento en la temperatura promedio de 1.73°C, variaciones que generan una disminuirá del rendimiento de la producción del cultivo de un 7.86%. Para el ECC2 las variaciones son mayores con una disminución de la precipitación del 18.06% y un aumento de la temperatura de 3.31°C, afectando el rendimiento en un 37.86% respecto de la producción media de la Línea Base (21.63 t/ha/año). Se concluye que, según las simulaciones realizadas, el riego permite adaptar las condiciones de agua disponible en el suelo, al punto que mantener los rendimientos de la Línea base del cultivo de palma para los escenarios de cambio climático propuestos (ECC1 y ECC2). En ambos casos, en el análisis interanual mostro un incremento en los requerimientos hídricos del cultivo de palma de aceite conforme se establece la época seca. Además, que conforme el ECC se vuelva más intenso el agua disponible en el suelo disminuye aumentando los requerimientos de riego del cultivo de palma de aceite.

A population explosion has resulted in garbage generation on a large scale. The process of proper and automatic garbage collection is a challenging and tedious task for developing countries. This paper proposes a deep learning-based intelligent garbage detection system using an Unmanned Aerial Vehicle (UAV). The main aim of this paper is to provide a low-cost, accurate and easy-to-use solution for handling the garbage effectively. It also helps municipal corporations to detect the garbage areas in remote locations automatically. This automation was derived using two Convolutional Neural Network (CNN) models and images of solid waste were captured by the drone. Both models were trained on the collected image dataset at different learning rates, optimizers and epochs. This research uses symmetry during the sampling of garbage images. Homogeneity regarding resizing of images is generated due to the application of symmetry to extract their characteristics. The performance of two CNN models was evaluated with the state-of-the-art models using different performance evaluation metrics such as precision, recall, F1-score, and accuracy. The CNN1 model achieved better performance for automatic solid waste detection with 94% accuracy

Las empresas constructoras en Panamá no cuentan con profesionales, procesos ni la cultura organizacional necesaria para lograr los resultados esperados, existe una deficiente dirección; esto origina proyectos no culminados dentro del plazo, costo ni con la calidad esperada, otros no se terminan, gastos inasumibles, mala imagen empresarial, penalizaciones, pérdida de clientes, conflictos internos y externos. El origen del problema es que en Panamá no existe una metodología aplicable por los profesionales como guía general para proyectos de construcción. Esta investigación será descriptiva, utilizando el método inductivo, se partirá de normativas internacionales de metodologías tradicionales y ágiles actualmente aplicadas separadamente en el campo de dirección de proyectos. Mediante la presente investigación, se desarrollará una metodología híbrida en la que lo tradicional y lo ágil se complementan, con dicha integración se espera lograr gestiones robustas que incrementen la posibilidad de éxito en los proyectos de construcciones panameñas. El enfoque será mixto integrando datos cuantitativos y cualitativos. En esta investigación, se utilizará como base la Norma Internacional “Directrices para la Dirección y Gestión de Proyectos, ISO 21500”, que proporciona una descripción de alto nivel sobre conceptos y procesos de dirección de proyectos; los que se integrarán con conceptos y técnicas de metodologías ágiles. Al culminar esta investigación se espera validar una metodología híbrida de dirección para proyectos de construcción más dinámica y flexible, que permita a los directores planificar, ejecutar y dirigir más adecuadamente los proyectos de construcción en Panamá; logrando proyectos más exitosos, mayores beneficios económicos para las empresas constructoras, clientes más satisfechos y profesionales más capacitados.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español La mora (Rubus glaucus Benth), una fruta de alta demanda en el mercado por su aporte nutricional y cualidades agroindustriales. En Ecuador, es cultivada por pequeños y medianos productores de la sierra. La provincia con el nivel de producción más alto en 2019 fue Tungurahua con el 39 % de la producción nacional y rendimiento de 7.46 t/ha. El consumo de mora ha disminuido por temor de consumidores de comprar una fruta que está relacionada altas aplicaciones de agroquímicos. El uso de éstos se relaciona con un mayor costo de producción; y, riesgo para el ambiente y salud de agricultores como también de consumidores. Como objetivo general tenemos el diferenciar el impacto ambiental y económico de la producción convencional y agroecológica de mora en Tungurahua, Ecuador. Se realizó una revisión del manejo agronómico de los cultivos de mora con los productores de Tungurahua a través de entrevistas. Se registró una base de datos, donde se detalló: área de cultivo, agroquímicos utilizados detallando ingrediente activo y su concentración, número de aplicaciones y dosis de producto. En base a esta información se determinó la tasa de impacto ambiental de cada uno de los agricultores entrevistados. Se determinó la rentabilidad de cada agricultor entrevistado, determinando la tasa interna de retorno, periodo de recuperación de inversión y valor actual neto. Se obtuvieron los siguientes resultados y conclusiones. Se obtuvo una reducción del 24.54% de impacto ambiental con un manejo limpio en comparación con un manejo convencional del cultivo de mora. Al realizar el cálculo de indicadores de rentabilidad, los resultados nos proporcionaron excelentes resultados para inversión en este cultivo, como también el tiempo de recuperación de la inversión nos indica que en definitiva el cultivo es factible y vale la pena la inversión.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español En el Ecuador, una de las enfermedades de mayor preocupación es la diabetes mellitus por la cantidad de personas que la padecen y el número de fallecidos que se le atribuyen. En el año 2019 los hospitales declararon un total de 16.621 pacientes con Diabetes y según el registro estadístico de defunciones emitido por el INEC, es considerada como segunda causa principal de muerte del país al presentar una tasa de letalidad del 6.7% con un total de 4.890 fallecidos, justo por debajo de las enfermedades isquémicas del corazón que reportó una tasa letal del 11.7% representada por un total de 8.574 fallecidos. Por otro lado, a pesar de la influencia del ámbito genético, la alimentación juega un papel muy importante tanto para su desarrollo en una persona sana como para que aquella persona que la padece logre tener control de esta y pueda mantener un buen estilo de vida; sin embargo existen muchas razones por las que una mala alimentación es adquirida, una de ellas es la escasa cantidad de alternativas de alimentos pensados para el cuidado de la salud del consumidor o destinados a un sector específico de personas como es el caso de las personas diabéticas que debido a determinada actividad o rutina de ejercicio se ven limitadas a beber agua en lugar de las bebidas hidratantes del mercado debido al aporte de azúcar que estas brindan y que pueden generar un efecto adverso como la hiperglucemia al ser consumida en exceso. Ante esto, el presente trabajo tiene como objetivo el desarrollo de una bebida isotónica a base de fibra prebiótica soluble y determinar su efecto en la hidratación y en los niveles de glucemia de personas diabéticas tipo 2 como prototipo de nueva alternativa de recuperar electrolitos y mantener la salud intestinal sin inducir a hiperglucemia. Para este fin se realizó una investigación que permitió conocer los tipos de bebidas hidratantes, su composición y el papel de una buena hidratación en el organismo, así como también explorar las alternativas que el mercado local ofrece para la hidratación de personas diabéticas mediante una visita de campo a supermercados y una encuesta que permitió identificar el conocimiento de las personas sobre este tipo de productos. Finalmente, se logró desarrollar la bebida planteada pero sin embargo no fue posible cumplir el objetivo propuesto ya que la bebida desarrollada al ser comparada con el agua estadísticamente, no presentó diferencias significativas en el efecto sobre los indicadores del nivel de hidratación, es decir, los resultados sanguíneos obtenidos mostraron una pequeña diferencia en sus valores post-ingesta reflejando un descenso de la osmolalidad, pero de manera estadística no fueron significativos dichos efectos, por lo que se recomienda realizar una reformulación del producto y ampliar el tamaño de muestra en un posterior estudio para tener resultados mucho más reales.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español En el Ecuador, una de las enfermedades de mayor preocupación es la diabetes mellitus por la cantidad de personas que la padecen y el número de fallecidos que se le atribuyen. En el año 2019 los hospitales declararon un total de 16.621 pacientes con Diabetes y según el registro estadístico de defunciones emitido por el INEC, es considerada como segunda causa principal de muerte del país al presentar una tasa de letalidad del 6.7% con un total de 4.890 fallecidos, justo por debajo de las enfermedades isquémicas del corazón que reportó una tasa letal del 11.7% representada por un total de 8.574 fallecidos. Por otro lado, a pesar de la influencia del ámbito genético, la alimentación juega un papel muy importante tanto para su desarrollo en una persona sana como para que aquella persona que la padece logre tener control de esta y pueda mantener un buen estilo de vida; sin embargo existen muchas razones por las que una mala alimentación es adquirida, una de ellas es la escasa cantidad de alternativas de alimentos pensados para el cuidado de la salud del consumidor o destinados a un sector específico de personas como es el caso de las personas diabéticas que debido a determinada actividad o rutina de ejercicio se ven limitadas a beber agua en lugar de las bebidas hidratantes del mercado debido al aporte de azúcar que estas brindan y que pueden generar un efecto adverso como la hiperglucemia al ser consumida en exceso. Ante esto, el presente trabajo tiene como objetivo el desarrollo de una bebida isotónica a base de fibra prebiótica soluble y determinar su efecto en la hidratación y en los niveles de glucemia de personas diabéticas tipo 2 como prototipo de nueva alternativa de recuperar electrolitos y mantener la salud intestinal sin inducir a hiperglucemia.

As máscaras de protecção facial tornaram de uso obrigatório pela população em geral, nesta época da pandemia de Covid-19 mas a falta de consciência dos danos que advém do descarte incorrecto leva a danos ambientais. Foi proposto como objectivo deste estudo em contribuir os efeitos das máscaras descartáveis quanto a poluição do meio ambiente incentivando o descarte correcto das mesmas. Destaca-se o método de revisão narrativa e acomoda-se como um estudo de natureza qualitativa e teve a observação no local dos acontecimentos e também realizou-se uma busca na base de informações da MEDLINE, SciELO e Google Scholar e não se deixou de fora as recomendações oficiais maioritariamente da Organização Mundial da Saúde. A recolha de informação foi feita com base num questionário. Os resultados desta pesquisa são considerados satisfatório porque respondem aos objectivos traçados para o presente estudo. Concluiu-se que é necessário continuar com as acções de sensibilização da população em matérias de educação ambiental de modo que as pessoas percebam quais são os problemas ambientais que precisam de soluções para que o futuro ambiental não seja prejudicado e ter uma consciência quanto aos impactos ambientais. Continuar também a combater o alastramento da doença e no mínimo reduzir o uso das máscaras descartáveis optando pelo material reciclável como as máscaras caseiras que podem ser reutilizadas. Recomenda-se o descarte das máscaras de forma correcta e que se façam mais pesquisas capazes de educar e sensibilizar as populações sobre a gestão de residuos sólidos.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés To address the current pandemic, multiple studies have focused on the development of new mHealth apps to help in curbing the number of infections, these applications aim to accelerate the identification and self-isolation of people exposed to SARS-CoV-2, the coronavirus known to cause COVID-19, by being in close contact with infected individuals. The main objectives of this paper are: (1) Analyze the current status of COVID-19 apps available on the main virtual stores: Google Play Store and App Store for Spain, and (2) Propose a novel mobile application that allows interaction and doctor-patient follow-up without the need for real-time consultations (face-to-face or telephone). In this research, a search for eHealth and telemedicine apps related to Covid-19 was performed in the main online stores: Google Play Store and App Store, until May 2021. Keywords were entered into the search engines of the online stores and relevant apps were selected for study using a PRISMA methodology. For the design and implementation of the proposed app named COVINFO, the main weaknesses of the apps studied were taken into account in order to propose a novel and useful app for healthcare systems. The search yielded a total of 50 apps, of which 24 were relevant to this study, of which 23 are free and 54% are available for Android and iOS operating systems (OS). The proposed app has been developed for mobile devices with Android OS being compatible with Android 4.4 and higher. This app enables doctor-patient interaction and constant monitoring of the patient's progress without the need for calls, chats or face-to-face consultation in real time. This work addresses design and development of an application for the transmission of the user's symptoms to his regular doctor, based on the fact that only 16.6% of existing applications have this functionality. The COVINFO app offers a novel service: asynchronous doctor-patient communication, as well as constant monitoring of the patient’s condition and evolution. This app makes it possible to better manage the time of healthcare personnel and avoid overcrowding in hospitals, with the aim of preventing the collapse of healthcare systems and the spread of the coronavirus.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Español Patient care and convenience remain the concern of medical professionals and caregivers alike. An unconscious patient confined to a bed may develop fluid accumulation and pressure sores due to inactivity and deficiency of oxygen flow. Moreover, weight monitoring is crucial for an effective treatment plan, which is difficult to measure for bedridden patients. This paper presents the design and development of a smart and cost-effective independent system for lateral rotation, movement, weight measurement, and transporting immobile patients. Optimal dimensions and practical design specifications are determined by a survey across various hospitals. Subsequently, the proposed hoist-based weighing and turning mechanism is CAD-modeled and simulated. Later, the structural analysis is carried out to select suitable metallurgy for various sub-assemblies to ensure design reliability. After fabrication, optimization, integration, and testing procedures, the base frame is designed to mount a hydraulic motor for the actuator, a DC power source for self-sustenance, and lockable wheels for portability. The installation of a weighing scale and a hydraulic actuator is ensured to lift the patient for weight measuring up to 600 pounds or lateral turning of 80 degrees both ways. The developed system offers simple operating characteristics, allows for keeping patient weight records, and assists nurses in changing patients’ lateral positions both ways, comfortably massage patients’ backs, and transport them from one bed to another. Additionally, being lightweight offers reduced contact with the patient to increase the healthcare staff’s safety in pandemics; it is also height adjustable and portable, allowing for use with multiple-sized beds and easy transportation across the medical facility. The feedback from paramedics is encouraging regarding reducing labor-intensive nursing tasks, alleviating the discomfort of long-term bed-ridden patients, and allowing medical practitioners to suggest better treatment plans Shafi, Imran and Farooq, Muhammad Siddique and De La Torre Díez, Isabel and Breñosa, Jose and Martínez Espinosa, Julio César and Ashraf, Imran UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, josemanuel.brenosa@uneatlantico.es, ulio.martinez@unini.edu.mx, UNSPECIFIED

El índice de calidad del agua determinado en el rio Chirapi se mantuvo sin variación significativa durante los dos años (tres
muestreos octubre-noviembre del 2017 y un muestreo noviembre 2019) de estudio. Al analizar los 6 puntos de estudio se evidencia que hay un decrecimiento en el índice de calidad desde el primer punto hasta el sexto punto se tiene un ICA
promedio de: 86, 83, 82, 85, 79, 61 respectivamente. Lo que equivale a un ICA de carácter bueno en los primeros 5 puntos y
regular en el último. De los nueve parámetros sugeridos en el análisis del ICA-NSF se eliminó el aporte de variación de temperatura debido a que la temperatura ambiental varía mucho en función de las condiciones meteorológicas como lluvia, cielos despejado o cubierto, presencia de vegetación, etc. El principal factor que interviene en el decrecimiento del ICA es el incremento de coliformes fecales y DBO5 debido a las descargas domésticas.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español Según Instituto Interamericano de Cooperación para la Agricultura (IICA, 2015), en Costa Rica se ocupa un 41,7% del territorio en actividades agropecuarias. Las mismas han sido señaladas por su fuerte emisión de gases de efecto invernadero (GEI); sin embargo, dicha actividad promueve la formación de reservorios de carbono en el suelo. Por medio de la producción de materia seca neta fotosíntesis y su posterior deposición como materia orgánica; esto causa una relación entre la ganadería y el cambio climático, al lograr que parte de los GEI se depositen en el suelo.Se realizaron comparaciones entre tres diferentes usos de suelo (bosque, cultivos perenes, semi perennes y anuales) por medio de calicatas. Se dio a conocer el porcentaje de carbono, densidad aparente y carbono orgánico total del suelo a cada 20 cm de profundidad en cada calicata. Se tenía el conocimiento que podían existir diferencias entre los diferentes escenarios, sin embargo, la intención del proyecto fue conocer el cuanto, en un tiempo definido, dependiendo del uso de suelo. El estudio se realizó en la finca FEIMA-Turrialba, Costa Rica; en un suelo Anthrosol con una particularidad, el cual el material parental, viene de otro sitio, precisamente donde se encuentra la represa de Angostura, en Turrialba, Cartago, Costa Rica. El material en su momento llegó por medio de maquinaria y el ser humano hace aproximadamente 20 años. Ha sido del mismo propietario y el uso al suelo ha sido el mismo desde que se formó. Esta particularidad permitió definir y realizar una comparación en igualdad de condiciones y tiempo en los diferentes escenarios. El suelo con la cobertura de cultivo semi perenne (banano), fue el obtuvo mayor porcentaje de carbono en los primeros 20 cm, seguidamente por los cultivos anuales. En cuanto la variable de la densidad aparente, no hubo diferencias significativas en ninguna comparación de las coberturas. Obteniendo resultados entre 1.1-1.3 g/cm3 indicando que no hay compactación en el suelo sin importar la cobertura en donde se encuentre. En referencia al carbono orgánico total, cobertura con cultivo semi perenne fue el que obtuvo mayor cantidad de COS, un total de 169 ton/ha, seguido por los cultivos anuales de 154 ton/ha.

Ibero-american International University > Teaching > Master's Final Projects Cerrado Español En la presente investigación se realizó un Diagnóstico y propuesta del modelo Z2 Altman en la empresa Constructora Etinar S.A. de la ciudad de Guayaquil-Ecuador en el periodo 2017 -2020, en donde se verificó la situación económica y financiera de la empresa durante el periodo antes mencionado. A partir de ello, se tuvo como objetivo, elaborar un diagnóstico financiero y una propuesta a futuro de poder aplicar en la empresa el modelo econométrico Z2 Altman y así detectar si la misma estaría en una posible bancarrota o insolvencia financiera. La metodología que se aplicó es el trabajo de campo y documental, en la primera técnica se efectúa una entrevista al gerente general y contador general de la empresa para así contar con información valiosa que pueda ayudar con la aplicación de cada uno de los objetivos planteados y en la segunda técnica se realiza el análisis vertical, horizontal y los ratios financieros del balance de situación y cuenta de resultados. Los resultados obtenidos permiten rebelar la situación financiera de la empresa, en donde se encuentra económicamente con cierta variabilidad pero estable durante todo el periodo, identificando que el año 2017 fue el mejor de todos ya que el total de sus activos fue de $32.132.243,00 con utilidad neta de $940.322,00 siendo el de mayor crecimiento durante los 4 años y referente a la aplicación del modelo Z2 Altman se alcanzó resultados muy interesantes en donde la empresa para el año 2017 estuvo en zona gris pero no en peligro de quiebra y el resto de años no tuvo ningún peligro de quiebra, es decir los resultados fueron muy positivos. Se determina que el modelo econométrico Z2-Score de Edward Altman usa una técnica estadística de nombre análisis discriminante múltiple lo cual es totalmente práctico y de fácil aplicación, en donde sus resultados nos permiten conocer el escenario económico durante el periodo 2017 – 2020 suministrando información positiva para la toma de decisiones de los accionistas y directivos de la empresa Etinar S.A. concluyendo que es totalmente viable y necesario aplicar este modelo en un futuro.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español La diversidad de actividades industriales en la actualidad, incorporan en sus procesos el uso constante de agua ya sea como materia prima o como un recurso adicional para llevar a cabo sus procesos; este uso constante repercute en un deterioro en la calidad de esta una vez ha terminado el proceso productivo, por lo que es responsabilidad de cada empresa el tratamiento de las aguas residuales generadas para no alterar los ecosistemas ni generar impactos ambientales negativos. En el caso del sector petrolero el agua es un subproducto generado a partir de la extracción de petróleo y gas de los pozos productores, y es catalogada como el mayor producto contaminante del proceso productivo, debido a la cantidad diaria producida y a sus características fisicoquímicas y biológicas que hacen complejo su tratamiento y disposición final. En este documento; el estudio se centra en el diseño de una planta de tratamiento de aguas residuales adaptable a las características fisicoquímicas y biológicas del agua de producción de campo platanillo, generando así una reestructuración, nuevo diseño o complemento de la planta de tratamiento de inyección de agua (PIA) ya existente. La metodología desarrollada para el proyecto se realiza bajo enfoque cuantitativo y cualitativo y bajo el esquema de diseño de proyecto, del tipo cuasiexperimental, con un corte transversal; mediante el cual se presenta la oportunidad y necesidad de mejora de la planta de tratamiento de aguas de formación de campo, para mejorar las características del efluente a inyectar, reduciendo los impactos ambientales negativos que surgen al momento de la inyección del agua al pozo inyector establecido en campo y aumentando la eficiencia del proceso de tratamiento, aprovechando el agua tratada para usos sostenibles como riego, uso agrícola o vertimiento a cuerpos de agua.En el desarrollo del trabajo se centra al lector en la normatividad ambiental aplicable en Colombia, fundamentos de pretratamientos, tratamientos primarios, secundarios y terciarios; así como en las características de los fluidos provenientes de pozos productores, para posteriormente entrar en el proceso de caracterización del agua de formación de campo platanillo, el diseño de la planta de tratamiento y la evaluación de los resultados a través de la simulación del proceso con ayuda de los resultados obtenidos de la caracterización del efluente.Finalmente se simula el proceso con ayuda del software GPS-X, utilizando el modelo estacionario y variables cinéticas y estequiométricos establecidas por defecto en el programa; estableciendo en el tratamiento etapas de pretratamiento, tratamiento primario, secundario y tratamiento terciario; como parte final se proponen como estrategias para el uso sostenible del agua de formación, actividades como riego, uso agrícola, reutilización en actividades propias de campo; así como también se recomienda que las opciones de vertimiento y reinyección deben ser actividades consideradas entre las ultimas opciones de destino de efluentes.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español Inversiones MR, S.A. de C.V. es una empresa familiar fundada en 2004, ubicada en El Salvador, Centroamérica que se dedica a brindar servicios de ingeniería térmica.En sus inicios solamente se ofrecían servicios de mantenimiento y reparación de calderas de vapor y con el paso del tiempo se han ido agregando servicios y productos a disposición de sus clientes.Como complemento al mantenimiento y reparación de calderas, se invirtió en la compra de analizadores de combustión para ofrecer el servicio de lectura, análisis y emisión de certificados de gases de combustión en calderas para cumplimiento de normativas que marcan los límites para la emisión de gases al medio ambiente.Por tratarse de una empresa familiar en un principio el fundador fue quien se capacitó para el manejo de los analizadores y luego su hijo también recibió capacitaciones en la fabrica de analizadores de gases Bacharach en Pittsburgh, PA en Estados Unidos. Dicha marca es distribuida por la empresa desde 2012.Por motivos de costos y desconocimiento sobre trámites de exportación se coordinaba un viaje anual para calibrar tanto analizadores propios de la empresa como analizadores propiedad de algunos clientes para quienes era complicado coordinar la disponibilidad de enviar sus analizadores por lo que se decidió montar un laboratorio de calibración local avalado por el fabricante.Debido a que solamente personal limitado tuvo la oportunidad de capacitarse con el fabricante para la reparación, mantenimiento y calibración de los equipos estas actividades están limitadas a la disponibilidad de tiempo de estas personas quienes desempeñan labores gerenciales-administrativas por lo que es necesario transferir los conocimientos y delegar en otros empleados las labores del laboratorio de calibración.Por lo tanto resulta de suma importancia diseñar un manual de procedimiento para la gestión del laboratorio de calibración de analizadores de gases de combustión que sirva como guía técnica para el o los empleados encargados de brindar los servicios de calibración puedan brindar los servicios contando con la supervisión del personal originalmente capacitado para dicha labor.El diseño de la investigación fue no experimental ya que los fenómenos observados fueron tomados tal como se dan en su contexto natural, además fue de tipo descriptivo ya que el fin de estudio es describir los procesos que lleva a cabo la organización. Considerando la información obtenida con antelación, la investigación inicialmente fue exploratoria ya que se investigaron los problemas que existen en la organización, lo cual reveló el funcionamiento de la empresa para posteriormente sugerir soluciones. Se realizó una encuesta a los clientes actuales para evaluar su apreciación sobre los servicios brindados dando resultados favorables a la empresa.

El objeto del trabajo fue dar solución al problema de los residuos sólidos voluminosos del área metropolitana de la provincia de Misiones (AMPGC), diseñando un sistema de tratamiento acorde a su vulnerabilidad económica, ecológica y social, en virtud de erradicar los puntos de arrojo y minibasurales urbanos y los basurales suburbanos. Para lo cual se realizó una caracterización de sus residuos sólidos urbanos aplicando la norma ASTM D5231-92 y de sus residuos de construcción y demolición empleando el modelo de transferencias ponderadas. Respecto a los residuos de poda y desbrozado, residuos metálicos, neumáticos fuera de uso y residuos de aparatos eléctricos y electrónicos, se estimó su volumen de generación relevando los distintos programas de retiro implementados por cada municipio del AMPGC. En referencia a la caracterización de los residuos sólidos urbanos, la materia orgánica (51,80%) fue la más representativa, seguida por los materiales con potencial de reciclado, como plástico (13,90%), vidrio (7,90%), papel y cartón (7,80%), tetrabrik (2,60%) y metales/aluminio (2,20%). Para la determinación de residuos de construcción y demolición se partió de la planilla de cómputo y presupuesto de una construcción característica para luego organizar los elementos materiales a los que se les aplicó el modelo matemático de transferencias ponderadas, lo cual propició convertir los elementos consumidos en volumen de residuos generados. Como limitación del método de caracterización de residuos sólidos urbanos, se determinó que los resultados son representativos de cada ciudad y de la estación invernal. Con ello se diseñó el Centro Integral de Tratamiento compuesto por operaciones unitarias para cada corriente de residuos al que se incluyó un Centro de Interpretación Ambiental y un Observatorio de Residuos. Se mantuvo como modo de disposición final el uso del relleno sanitario existente, donde se dispondrán los residuos voluminosos sin valor energético o de recupero, transformados previamente para su aceptación.

En este trabajo de investigación se llevó a cabo el diseño de un generador eléctrico alternativo que mediante la inducción electromagnética de los conductores eléctricos permitió obtener energía eléctrica para satisfacer la necesidad de iluminación de las empresas pesqueras de la parroquia de Chanduy del cantón Santa Elena del Ecuador. La metodología utilizada tuvo un enfoque cuantitativo a través del cual se aplicó una encuesta a 36 funcionarios administrativos gerenciales y 59 funcionarios técnicos u operativos pertenecientes a 50 empresas ubicadas en Chanduy para obtener datos en relación al grado de satisfacción (calidad y continuidad) sobre la energía eléctrica que recibe este sector industrial pesquero. Los resultados obtenidos determinaron que no existe un total grado de conformidad respecto a la calidad de energía eléctrica que se recibe en Chanduy, ya que ambos grupos de encuestados coincidieron en que no se logra cubrir de forma completa las necesidades de iluminación, aspecto que resulta fundamental para el desarrollo de sus actividades ya que muchas de estas se llevan a cabo no solo en horario nocturno, sino incluso en horario matutino y vespertino. De esta manera, el diseño de este generador eléctrico fue una actividad necesaria para el sector de Chanduy, realizado de forma sistemática y analizando cada uno de los aspectos que pudieron condicionar la efectividad de su funcionamiento, incluyendo el contexto geográfico de esta parroquia y las condiciones físicas de cada una de las empresas participantes en el estudio. Todo esto con la finalidad de que esta propuesta fuera ajustada de manera eficiente y lograra satisfacer las demandas de dicho sector. Con la finalidad de validar la operación en el generador alternativo y tener la certeza de su funcionamiento, se mantuvo en operación y observación durante una semana y en este periodo de tiempo no presento cambios en su operación y funcionamiento.

Los Sistemas de gestión de Calidad en la actualidad se han convertido en una necesidad en un mercado globalizado así mismo la gestión en la seguridad y salud en el trabajo (SST) es una obligación legal y social para todas las organizaciones, adicionalmente estos sistemas brindan ventajas competitivas para las empresas y sus trabajadores. Es por ello que el diseñar un Sistema Integrado de Calidad y Seguridad y Salud en el trabajo se considera un elemento fundamental para el éxito de cualquier organización y así lo ha entendido la alta gerencia de la empresa Industria de Alimento Don Pancito S.A.S, objeto del desarrollo del proyecto Final. Para poder entrar en el mercado global, es necesario implementar sistemas de gestión, no solo para competir, si no para poder responder a la creciente demanda del mercado y poder brindar los estándares de calidad del producto, medio ambiente, seguridad y salud ocupacional, los cuales trabajan en el mantenimiento y mejoramiento continuo. La Industria de Alimento Don Pancito S.A.S., con el propósito de lograr productos con altos estándares de calidad decidió implantar un sistema integrado de gestión de calidad con base en cuatro normas de referencia las cuales son BPM, normas HACCP, la norma ISO 9001:2015 y la norma ISO 45001, que se desarrollaran en conjunto para lograr garantizar la inocuidad de sus productos, satisfacer las necesidades del cliente y ser competitivos en el mercado global. Así mismo el diseño propuesto encuentra su justificación al plantearse necesidades de conducir procesos estratégicos, operacionales y de apoyo a fin de fomentar la mejora continua e integración de todas las áreas internas de la organización. También busca dar cabida a todos los entes que interactúan con la organización y deben obtener satisfacción de la organización. Esto se logra, mediante el apego de la organización a una misión, visión, valores para asegurar encaminar la organización en este sentido. Molina Arteta, Angie Melissa artetangie@gmail.com

El nivel de investigación es correlacional, no experimental, se realizó entre los años 2020-2022. Respecto a la metodología es de enfoque cuantitativo. Los instrumentos de recolección de datos se aplicaron a cincuenta (50) gerentes agropecuarios en las Unidades de Producción Agropecuaria de Arroz, Café, y Piaractus brachypomus y Oreochromis sp., del Norte de Santander. Los resultados determinan correlación directa y estadísticamente significativa entre la falta de competencia de los gerentes y la falta de articulación con el sector público como factores que afectan la innovación en las MIPYMES agropecuarias (p < 0.05). Igualmente se evidenció correlación positiva entre la falta de competencias de los gerentes y la falta de articulación con el sector privado, la falta de transferencia tecnológica y gestión del conocimiento, como factores que afectan la innovación en las MIPYMES agropecuarias (p< 0.05). Asimismo, hay correlación positiva y estadísticamente significativa entre la falta de transferencia tecnológica y gestión del conocimiento, como factores determinantes de la poca innovación en estas empresas agropecuarias (p < 0.05). Se pudo determinar que la gestión gerencial, gerencial específicamente las competencias gerenciales se afectan y difieren significativamente respecto a las inversiones realizadas por los empresarios en el pago de servicios técnicos a universidades o instituciones, observándose una mayor falta de competencias gerenciales en aquellos empresarios que han invertido pocos recursos en la prestación de servicios técnicos (p < 0.05). Finalmente se diseñó el modelo de gestión adaptativa de proyectos a la gestión de las MIPYMES agropecuarias del Norte de Santander. Se concluye que la gestión adaptativa de proyectos es una alternativa adecuada a la gestión gerencial de las MANS. Contreras Rangel, Jael jael.contreras@doctorado.unini.edu.mx

Ibero-american International University > Teaching > Final Master Projects Cerrado Español Esa investigación, se desarrolló en el Barrio Malvinas Argentinas, de la ciudad de Río Grande en la provincia de Tierra del Fuego. Está orientada en obtener información sobre antecedentes en el barrio con respecto a los residuos sólidos y también en diseñar un plan de gestión en donde se propongan estrategias de minimización de residuos sólidos para el barrio, en donde los habitantes se comprometan a cuidar el medio. Dentro de la ciudad de Río Grande, todavía no existe normativa alguna que regule ni la recolección de residuos diferenciada ni su posterior tratamiento, habiendo quedado atrasada en el tiempo con respecto a las nuevas metodologías que se aplican en el resto del país para ambos puntos. Por lo que esta investigación, tuvo como objetivo, indagar sobre lo que los habitantes conocen, y también incentivarlos a que, por sus propios medios, gestionen una minimización en la producción diaria de residuos sólidos utilizando acciones como el reciclaje y la reutilización de los materiales diarios, como también la separación de lo fermentable de lo no fermentable para producir compostaje, retribuyendo a la naturaleza con tierra rica en materia orgánica. El fin de esta investigación, fue concientizar a los habitantes, en primera instancia de este barrio, para que en un futuro no muy lejano y si así lo deseen, sea un tema a tratar por los políticos de turno, por lo que este trabajo pueda funcionar como puntapié inicial en el tema, donde se pueda dar la recolección diferenciada de los residuos, y también su posterior tratamiento. Sobre todas las cosas, que se genere un ida y vuelta entre los habitantes y las entidades correspondientes, donde se haga hincapié en la educación ambiental.

Vale indicar que la zona en donde se establecerá el primer local será en el casco bancario de la ciudad de Guayaquil.Por otra parte, se evidencia que el período de recuperación es menor a dos años y medio, además se presenta una TIR del 47,2% lo cual indica que el presente proyecto es viable de implementar. Así mismo, los datos económicos presentan un escenario bastante favorable dentro de la propuesta de implementar este emprendimiento en la ciudad más importante del Ecuador.

El acceso al agua potable es una necesidad inevitable en las sociedades. Debido a la escasez de este recurso, es necesario replantear la manera en que se gestiona su servicio de distribución de tal forma que sea cada vez más eficiente. Uno de los indicadores más importantes para ofrecer el servicio de agua y lograr su sostenibilidad es el Agua No Facturada (ANF). En el Perú, este indicador bordea el 35% (SUNASS 2019), los cual sugiere que aproximadamente un tercio del agua producida no es facturada. Bajo estas circunstancias es imposible determinar qué parte de ese tercio ha sido desperdiciado y qué parte ha sido utilizado, pero no contabilizado. Esta investigación propone un modelo para el monitoreo y administración remota de la red de distribución de agua potable aplicando tecnologías IoT en la ciudad de Huacho, Perú. El estudio es no experimental – transaccional, y se realiza de manera descriptiva. Además de establecer el marco sobre el cual el sistema debe diseñarse, se realiza un análisis multicriterio basado en TOPSIS para seleccionar la red IoT más adecuada para su implementación. Asimismo, se realiza un estudio de los equipos necesarios tomando en cuenta sus características técnicas, los registros legales correspondientes y los requerimientos del sistema.A partir de las propiedades de los datos obtenidos, se proponen criterios de análisis para establecer situaciones anormales dentro del comportamiento de la red de agua basándonos en la Norma Metrológica Peruana vigente, y de esta manera explorar las posibles causas y el impacto de cada una de ellas. Los resultados obtenidos nos muestran que es posible implementar un sistema de Telemetría para la red de distribución de agua, que aumente la eficiencia del servicio y utilizando la tecnología IoT más adecuada para el lugar de estudio.

La investigación tuvo como objetivo diseñar e implantar una metodología basada en la transformación digital de forma ágil y en tiempos cortos que permitiera a las empresas PYME del sector de logística ligera del Perú incrementar su competitividad considerando sus necesidades y capacidades empresariales. Para la investigación se utilizó un enfoque de investigación mixto con un diseño exploratorio secuencial (DEXPLOS), observacional y experimental; siendo que la población en estudio fueron 750 PYMES con una muestra de 255 empresas y muestreo probabilístico estratificado. Los criterios de inclusión fueron: tener definidas sus estrategias competitivas, mínimo un año de operación y licencias de funcionamiento y postal. El instrumento de investigación fue un cuestionario compuesto por 189 preguntas distribuidas en variables como estrategia, rentabilidad, nivel técnico, productividad, calidad y trazabilidad cuyo objetivo fue el de identificar el estado de Transformación Digital de cada PYME y generar una hoja de ruta personalizada que permitiera establecer las acciones a implantar para mejorar el estado inicial. Los resultados iniciales permitieron identificar que solamente el 17.53 % de PYMES superaron el nivel intermedio y su utilidad promedio se situó en 23,37 %, sin embargo, cuatro meses posteriores a la implementación de la hoja de ruta resultante de la metodología, el número de PYMES que superaron el nivel intermedio se incrementó a 27.28 % y la utilidad promedio mejoró al 23.37 % lo que representa un incremento de la competitividad del 11.85 %.Por lo tanto, se concluyó que la implementación de la metodología propuesta permite elevar a corto plazo la competitividad de las PYMES de logística ligera a través del incremento del nivel de la Transformación Digital mediante un modelo personalizado y acorde a sus necesidades y capacidades.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español El presente trabajo estuvo orientado al diseño de una planta de tratamiento de aguas residuales (PTAR) para la empresa Bioingeniería Autosustentable S.A. de C.V. en la ciudad de Metepec, Estado de México. Bioingeniería es una empresa dedicada al diseño, construcción, operación y mantenimiento de PTAR´S. A dicha empresa le es solicitado el diseño de una PTAR para sanear las aguas residuales de la industria de jugos denominada Jugos del Bajío dedicada al envasado de jugo o pulpa de fruta, dicha empresa de jugos tiene la necesidad de sanear sus aguas residuales para contribuir a un cuidado ambiental. Con este proyecto se busca cubrir la necesidad de sanear las aguas residuales generadas y al mismo tiempo se tiene la oportunidad de generar el proyecto para sanear las aguas residuales. El objetivo general fue diseñar una PTAR (diseño de un sistema de tratamiento de aguas residuales). Para el diseño de la PTAR se tomaron en cuenta diferentes situaciones que intervinieron en su desarrollo, como el caudal de descarga, características fisicoquímicas del agua residual, área disponible para la instalación de la PTAR. La metodología para el desarrollo de este proyecto tomo en cuenta la realización de análisis para la caracterización del agua residual, para la caracterización se contrató un laboratorio acreditado ante la Entidad Mexicana de Acreditación (EMA) dicho laboratorio utilizo como base el método de muestreo NMX-AA-003-1980, el muestreo se realizó de 6 muestras en un periodo de 24hrs debido a que así se recomienda en la NOM-002-SEMARNAT-1996 en su tabla 2 frecuencia de muestreo según el tiempo que opera el proceso productor de las aguas residuales. Se identificaron los parámetros a considerar para el diseño de la PTAR como Demanda Bioquímica de Oxígeno al 5to día (DBO5), Demanda Química de Oxigeno (DQO), Solidos Suspendidos Totales (SST) entre otros, así mismo la solicitud fue que el agua residual tratada cumpliera con la NOM-002-SEMARNAT-1996 dicha norma es para la descarga de aguas residuales tratadas y descargadas al sistema de alcantarillado municipal. Por lo que el contenido y estructura de dicho proyecto se genera con la caracterización del agua residual, se verifico la biodegradabilidad del agua residual para someterla a un proceso biológico de depuración, así mismo se analizó la presencia de agentes tóxicos, al mismo tiempo se generó un diagrama de bloques que nos ayudó a conocer que etapas del proceso son necesarias para adecuar el agua a las condiciones de saneamiento como lo son en pH y temperatura, dicho diagrama de bloques evoluciono hasta quedar plasmadoen un arreglo general el cual culmino con nuestro diseño de la PTAR, para llegar hasta esta evolución se pasó por el proceso de utilizar parámetros de diseño especialmente para el reactor y sedimentador los cuales son elementos base en el proceso de saneamiento, utilizando variables biocinéticas y otras, como lo son el coeficiente de crecimiento y decaimiento celular, tiempo medio de retención celular, relación alimento/microorganismo, ya que todo esto en conjunto proporcionaron las volumetrías necesarias para el sistema de tratamiento de aguas residuales.

Ibero-american International University > Research > Articles and Books Cerrado Inglés The Internet of Things (IoT) is a revolutionary technique of sharing data for smart devices that generates huge amounts of data from smart healthcare systems. Therefore, healthcare systems utilize the convergence power and traffic analysis of sensors that cannot be satisfactorily handled by the IoT. In this article, a novel mutation operator is devised and incorporated with the differential evolution (DE) algorithm. Two tests have been conducted in the validation process. Firstly, the newly dual adaption-based operators incorporated with the differential evolution algorithm are being proposed. The proposed approach provides sufficient diversity and enhances the search speed of nature’s local and global search environments in the problem. The proposed method incorporates the application of IoT-based smart healthcare. Second, an application-based test has been conducted, in which the proposed approach is applied to the application in the smart healthcare system. Therefore, IoT sensor deployment is an optimization problem to minimize service time, delay, and energy loss by considering the communication constraint between sensors(objects). The proposed algorithm is applied in this article to solve this optimization problem. Further, in the experimentation and comparative study, the proposed method is superior to the standard evolutionary algorithms in IoT applications concerning the minimum number of function evaluations and minimization of traffic services.

Se plantea como Objetivo General, “Formular una propuesta de implementación de Inteligencia Artificial en áreas de Atención al Cliente, a través de la aplicación de un chatbot para los comercios de bienes y servicios que cuenten con una tienda virtual u e-commerce, en la ciudad de Asunción - Paraguay”. Para ello la Metodología utilizada fue de enfoque Cuantitativo, para medir la realidad objetiva investigada, es decir despúes de hacer la pregunta de investigación (encuesta) se ha planteado una respuesta alternativa, buscando comprobarla a través de técnicas de recolección de información estableciendo datos estandarizados, como por ejemplo haciendo la misma pregunta con igual número de respuesta, con las mismas formas a toda la población de estudio, ha permitido en nuestro caso de la encuestas presentar de manera estadística los resultados, que han arrojados unos indicadores muy alentadores como por ejemplo; el 80% de las respuestas de nuestro chatbot fueron correctas a las consultas planteadas por cada usuario o el sistema ha entendido correctamente, respondiendo con bastante claridad a cada pregunta; además se ha observado una reducción de mensajes vía correo electrónico, por implementación del chatbot en la tienda virtual de figpaltrading.com; también hemos experimentado un aumento de ventas en el mes de implementación del Chat Bot, lo que implica una cantidad cada vez mayor de clientes que han necesitado la asistencia en la operativa de atención al cliente para todo tipo de consultas en la tienda virtual, no requiriendo la contratación de más personal para el efecto, hecho que corrobora la escabilidad de nuestro chatbot. Se demuestra que la implementación de IA a través de la aplicación de un chat bot favorece el desarrollo y crecimiento de las plataformas de e-commerce, representando mayores ingresos por la escabilidad y mejora de servicio de atención al cliente antes y despues de cada compra. Al mismo tiempo, estamos utilizando un canal más barato, ni SMS, ni llamadas, ni email, sino un canal de Chat, contando con una interfaz super amigable, que ayudará que los usuarios usen más ese tipo de contacto a mediano y largo plazo.

Este estudio de investigación se realizó con la finalidad de determinar los efectos de la cadena de valor del café en el desarrollo socioeconómico de los pequeños cafetaleros de Corquín, departamento de Copán-Honduras, para proponer estrategias participativas que contribuyan a fortalecer la productividad y posicionar el rubro, para ello se han realizado diversas acciones en las que se incluye el diagnosticar los diferentes eslabones de la cadena del café que intervienen en el desarrollo socioeconómico de los pequeños cafetaleros de Corquín, analizar el actual desarrollo socioeconómico de estos y la planeación de estrategias participativas en pro del desarrollo que contribuyan fortalecer la productividad y posicionar el rubro del café enfocándose en la producción de los pequeños cafetaleros. La metodología que se empleó se encuentra conformada por un enfoque mixto, un alcance descriptivo y un diseño no-experimental transversal para la parte cuantitativa e investigación acción para la parte cualitativa, la población que se utilizó se encontró conformada por 140 pequeños cafetaleros y 14 organizaciones, siendo a estos a los cuales se les aplicaron las entrevistas y encuestas empleadas para la recolección de la información. Entre los resultados se muestra la importancia de las organizaciones gubernamentales y no gubernamentales en el proceso productivo del café y como estas han ayudado a que se impulsen las zonas cafetaleras de Honduras y de la región investigada, además se ha podido constatar que la mayor parte de los pequeños cafetaleros tiene el mayor de los cuidados en cuanto a control de malezas, plagas y enfermedades, tratan de emplear mayormente como tecnología la fertilización de los cultivos, además estos han logrado mejorar sus condiciones de vida por medio de las cosechas recolectadas de sus plantaciones, esto les ha permitido optar por tener mejores condiciones en sus viviendas, se muestra que la mayor parte de las carreteras se encuentran en buen estado lo que facilita la movilización del café extraído de las fincas hacia las viviendas y posteriormente hacia el exterior de las fincas. Como conclusión se menciona la importancia de seguir impulsando el desarrollo de los cafetaleros por medio de la integración de mejores procesos de capacitación, apoyo en cuanto a la dotación de mayor cantidad de insumos y la oportunidad de crecimiento a través de la comercialización de los productos, además, se menciona que la calidad de la producción no depende exclusivamente de los pequeños cafetaleros, sino que en este proceso se involucran otros participantes como ser los proveedores de insumos, lo cuales dotan a las fincas de todo el material y herramientas necesarias para poder obtener un cultivo con la calidad deseada, además del involucramiento de las organizaciones públicas y privadas las que han impulsado el desarrollo de los pequeños cafetaleros a través de diversas acciones y estrategias.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The diagnosis of early-stage lung cancer is challenging due to its asymptomatic nature, especially given the repeated radiation exposure and high cost of computed tomography(CT). Examining the lung CT images to detect pulmonary nodules, especially the cell lung cancer lesions, is also tedious and prone to errors even by a specialist. This study proposes a cancer diagnostic model based on a deep learning-enabled support vector machine (SVM). The proposed computer-aided design (CAD) model identifies the physiological and pathological changes in the soft tissues of the cross-section in lung cancer lesions. The model is first trained to recognize lung cancer by measuring and comparing the selected profile values in CT images obtained from patients and control patients at their diagnosis. Then, the model is tested and validated using the CT scans of both patients and control patients that are not shown in the training phase. The study investigates 888 annotated CT scans from the publicly available LIDC/IDRI database. The proposed deep learning-assisted SVM-based model yields 94% accuracy for pulmonary nodule detection representing early-stage lung cancer. It is found superior to other existing methods including complex deep learning, simple machine learning, and the hybrid techniques used on lung CT images for nodule detection. Experimental results demonstrate that the proposed approach can greatly assist radiologists in detecting early lung cancer and facilitating the timely management of patients.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The diagnosis of early-stage lung cancer is challenging due to its asymptomatic nature, especially given the repeated radiation exposure and high cost of computed tomography(CT). Examining the lung CT images to detect pulmonary nodules, especially the cell lung cancer lesions, is also tedious and prone to errors even by a specialist. This study proposes a cancer diagnostic model based on a deep learning-enabled support vector machine (SVM). The proposed computer-aided design (CAD) model identifies the physiological and pathological changes in the soft tissues of the cross-section in lung cancer lesions. The model is first trained to recognize lung cancer by measuring and comparing the selected profile values in CT images obtained from patients and control patients at their diagnosis. Then, the model is tested and validated using the CT scans of both patients and control patients that are not shown in the training phase. The study investigates 888 annotated CT scans from the publicly available LIDC/IDRI database. The proposed deep learning-assisted SVM-based model yields 94% accuracy for pulmonary nodule detection representing early-stage lung cancer. It is found superior to other existing methods including complex deep learning, simple machine learning, and the hybrid techniques used on lung CT images for nodule detection.

Por lo tanto, en toda institución debe existir un líder capaz de guiar por el camino correcto a los colaboradores y a la misma institución, en pocas palabras debe ser el motivador, orientador, colaborador, comunicador, innovador y sobre todo solucionador de problemas. Por ello la presente investigación tiene como objetivo general analizar el Liderazgo y su incidencia en el desempeño laboral de los trabajadores del Gobierno Autónomo Descentralizado Municipal del Cantón Caluma, para posteriormente brindar sugerencias que permita elevar la incidencia del liderazgo en el funcionamiento eficaz de la institución antes mencionada. La metodología utilizada en el presente proyecto de investigación es de tipo cuantitativa y cualitativa, en cuanto a la población la compone todo el personal del Gobierno Autónomo Descentralizado Municipal del Cantón Caluma, que está conformada por ciento noventa y cinco trabajadores y al ser un universo de estudio pequeño se procedió a aplicar la encuesta a la totalidad de los trabajadores, es decir, desde el personal de limpieza hasta la máxima autoridad. Las técnicas e instrumentos de investigación utilizadas para la recolección de datos fueron: la encuesta/cuestionario y entrevista, es decir, el primer instrumento se aplicó a los trabajadores, mientras que la entrevista fue aplicado a la máxima autoridad de la institución. Los resultados del estudio indican que dentro de la organización no existe un correcto Liderazgo, debido a factores como: falta de comunicación, coordinación, no es sociable con los trabajadores, no cumple con los objetivos en el tiempo indicado etc. Por tal razón, se propuso un plan de acción, basado en el modelo de Fiedler con la finalidad de elevar la incidencia del Liderazgo en el funcionamiento eficaz del Gobierno Autónomo Descentralizado Municipal del Cantón Caluma. Además, se evidencia que en la institución no existe una comunicación afectiva y amigable entre sus trabajadores, tampoco han recibido capacitaciones, no existe compañerismo y en su mayoría lo califican a su líder como regular, ya que no aporta de manera positiva al desarrollo organizacional; así como también no soluciona los conflictos generados en la institución antes mencionada. El modelo de Fiedler se eligió, debido a que es una teoría utilizada para evaluar las cualidades de Liderazgo existente en la institución del Gobierno Autónomo Descentralizado Municipal del Cantón Caluma de la Provincia Bolívar, es decir, las empresas u organizaciones deben utilizar el presente modelo de Fiedler para ayudarse a cambiar la situación para que coincida con el líder en lugar de buscar nuevos líderes que coincidan con la situación. Además, este modelo también se puede usar para delegar a diferentes miembros de la administración las tareas o proyectos para los que son más adecuados.Por lo tanto, el autor Fiedler, argumenta que los líderes orientados a tareas son más efectivos o simplemente más eficaces en situaciones extremas de alto o bajo control, pero es importante mencionar que los líderes orientados a las relaciones tienden a ser más efectivos en situaciones extremas de control intermedio moderado.En la actualidad, las demandas del trabajo requieren que el líder esté completamente preparado para dirigir y administrar la organización, solo así es posible motivar a los empleados y aumentar la eficiencia de la empresa. El presente modelo de Fiedler, fue creado por el autor Fred Edward Fiedler, uno de los investigadores de psicología industrial y organizacional del siglo XX (1965 – 1967), con el propósito de gestionar la elección de líderes adecuados para cada tipo de grupo (Ruiz, 2019).El modelo de Fiedler, se encuentra en el libro de: A Theory of Leadership Effectiveness del autor Fred Edward Fiedler que fue publicado el 1 de enero de 1967.

La proliferación de proyectos de desarrollo en África en general y en Camerún en particular durante la última década contrasta con sus resultados que en la mayoría de los casos son ambiguos. Estas actuaciones dependen en gran medida de las estrategias y decisiones adoptadas por los actores que interactúan. El análisis estratégico es, por tanto, un enfoque fundamental para comprender mejor los resultados de los programas de desarrollo. En este marco encaja el método MACTOR (Godet, 2007), una aplicación de la racionalidad actancial en el análisis de las interacciones humanas. Permite identificar a todos los actores activos y pasivos que intervienen en un proyecto y definir la matriz de alianzas, conflictos, estrategias, tácticas y objetivos que persiguen estos actores. Este método abre la vía a un análisis activo de la gestión de los proyectos de desarrollo para identificar mejor sus puntos fuertes y débiles. Este artículo es una revisión sistemática de las cuestiones en juego en este método y su aplicación en el contexto camerunés. Destaca los determinantes teóricos del método y su relevancia en el análisis de gestión de proyectos bajo una racionalidad actancial.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Facial emotion recognition (FER) is an important and developing topic of research in the field of pattern recognition. The effective application of facial emotion analysis is gaining popularity in surveillance footage, expression analysis, activity recognition, home automation, computer games, stress treatment, patient observation, depression, psychoanalysis, and robotics. Robot interfaces, emotion-aware smart agent systems, and efficient human–computer interaction all benefit greatly from facial expression recognition. This has garnered attention as a key prospect in recent years. However, due to shortcomings in the presence of occlusions, fluctuations in lighting, and changes in physical appearance, research on emotion recognition has to be improved. This paper proposes a new architecture design of a convolutional neural network (CNN) for the FER system and contains five convolution layers, one fully connected layer with rectified linear unit activation function, and a SoftMax layer. Additionally, the feature map enhancement is applied to accomplish a higher detection rate and higher precision. Lastly, an application is developed that mitigates the effects of the aforementioned problems and can identify the basic expressions of human emotions, such as joy, grief, surprise, fear, contempt, anger, etc. Results indicate that the proposed CNN achieves 92.66% accuracy with mixed datasets, while the accuracy for the cross dataset is 94.94%.

Ibero-american International University > Research > Articles and Books Abierto Inglés The demand for digitization has inspired organizations to move towards cloud computing, which has increased the challenge for cloud service providers to provide quality service. One of the challenges is energy consumption, which can shoot up the cost of using computing resources and has raised the carbon footprint in the atmosphere; therefore, it is an issue that it is imperative to address. Virtualization, bin-packing, and live VM migration techniques are the key resolvers that have been found to be efficacious in presenting sound solutions. Thus, in this paper, a new live VM migration algorithm, live migration with efficient ballooning (LMEB), is proposed; LMEB focuses on decreasing the size of the data that need to be shifted from the source to the destination server so that the total energy consumption of migration can be reduced. A simulation was performed with a specific configuration of virtual machines and servers, and the results proved that the proposed algorithm could trim down energy usage by 18%, migration time by 20%, and downtime by 20% in comparison with the existing approach of live migration with ballooning (LMB) Gupta, Neha and Gupta, Kamali and Qahtani, Abdulrahman M. and Gupta, Deepali and Alharithi, Fahd S. and Singh, Aman and Goyal, Nitin UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, aman.singh@uneatlantico.es, UNSPECIFIED

Estimation of suspended sediment yield (SSY) is essential for management, planning, and designing in any river basin system. Estimation of SSY is critical due to its complex nonlinear processes, which are not captured by conventional regression methods. Rainfall, temperature, water discharge, SSY, rock type, relief, and catchment area data of 11 gauging stations were utilized to develop robust artificial intelligence (AI), similar to an artificial-neural-network (ANN)-based model for SSY prediction. The developed highly generalized global single ANN model using a large amount of data was applied at individual gauging stations for SSY prediction in the Mahanadi River basin, which is one of India’s largest peninsular rivers. It appeared that the proposed ANN model had the lowest root-mean-squared error (0.0089) and mean absolute error (0.0029) along with the highest coefficient of correlation (0.867) values among all comparative models (sediment rating curve and multiple linear regression). The ANN provided the best accuracy at Tikarapara among all stations. The ANN model was the most suitable substitute over other comparative models for SSY prediction. It was also noticed that the developed ANN model using the combined data of eleven stations performed better at Tikarapara than the other ANN which was developed using data from Tikarapara only. These approaches are suggested for SSY prediction in river basin systems due to their ease of implementation and better performance.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español La mortalidad y la incidencia por cáncer en el mundo, en Chile y en la Macro Región Sur, a la que se circunscribe este proyecto, ha crecido sostenidamente en los últimos 25 años, lo que lo convierte en un problema de salud pública. Por ello, el Ministerio de Salud Chileno insta a los Servicios de Salud, a intencionar esfuerzos para fortalecer la Red Asistencial Oncológica, a fin de resolver la demanda terapéutica, especialmente en quimioterapia y radioterapia, mejorando así el acceso y oportunidad a los tratamientos para el cáncer. El diseño de proyecto seleccionado como tipología de estudio, tiene como objetivo proponer un Diseño para la Red Oncológica Terapéutica para la Macro Región Sur, traducido en carteras terapéuticas más resolutivas para pacientes oncológicos y en mapas de derivación que cambian el actual flujo de pacientes que ingresan a tratamiento en cada Servicio de Salud involucrado. La metodología que utiliza el estudio comprende recopilación bibliográfica y estadística de daño por cáncer, a nivel de país y de la red asistencial analizada, a fin de explicitar la importancia del proyecto. La estadística de incidencia por cáncer, se utiliza para realizar un estudio de oferta y demanda, determinando brechas de prestaciones y recursos asistenciales necesarios para su resolución. Los resultados más relevantes, corresponden a la magnitud de la demanda de recursos asistenciales estimados, que superan en forma importante a la oferta existente. Es así como, la demanda sillones para quimioterapia es 2,6 veces la oferta, la demanda de camas hospitalarias para pacientes con cáncer es 3,9 veces la oferta y la demanda de aceleradores lineales es 4,5 veces la oferta. Estos resultados son la base del Diseño de Red, que aborda la reestructuración de la atención terapéutica en la Red Oncológica Macro Regional Sur y sus mapas de derivación, aportando además el fundamento para que los Servicios de Salud involucrados como Gestores de Red, planifiquen y gestionen su resolución. De las conclusiones más relevantes, consignar que la propuesta de Diseño de Red es sólo el punto de partida para las intervenciones que deben ser planificadas en conjunto por el colectivo los Servicios de Salud de la Red Macro Regional Sur. La tarea mayor, será el levantamiento de los proyectos de inversión en aquellos establecimientos que modifican su cartera de servicios para aumentar resolutividad, y luego, la gestión de los recursos financieros y humanos para la ejecución e implementación de los mismos. Otro importante esfuerzo, corresponderá a la formación de los profesionales médicos requeridos, ya que el sistema chileno de formación de especialidades médicas, presenta importantes restricciones, exigiendo que cada Servicio de Salud gestione cada cupo directamente con Minsal. Finalmente señalar que, se requiere que Minsal aborde la ampliación del registro poblacional de cáncer, ya que éste sólo existe en 5 de 29 Servicios de Salud, información de gran utilidad para una mayor precisión de la demanda.

Estos resultados son la base del Diseño de Red, que aborda la reestructuración de la atención terapéutica en la Red Oncológica Macro Regional Sur y sus mapas de derivación, aportando además el fundamento para que los Servicios de Salud involucrados como Gestores de Red, planifiquen y gestionen su resolución. De las conclusiones más relevantes, consignar que la propuesta de Diseño de Red es sólo el punto de partida para las intervenciones que deben ser planificadas en conjunto por el colectivo los Servicios de Salud de la Red Macro Regional Sur. La tarea mayor, será el levantamiento de los proyectos de inversión en aquellos establecimientos que modifican su cartera de servicios para aumentar resolutividad, y luego, la gestión de los recursos financieros y humanos para la ejecución e implementación de los mismos. Otro importante esfuerzo, corresponderá a la formación de los profesionales médicos requeridos, ya que el sistema chileno de formación de especialidades médicas, presenta importantes restricciones, exigiendo que cada Servicio de Salud gestione cada cupo directamente con Minsal. Finalmente señalar que, se requiere que Minsal aborde la ampliación del registro poblacional de cáncer, ya que éste sólo existe en 5 de 29 Servicios de Salud, información de gran utilidad para una mayor precisión de la demanda.

Antecedentes: En la península de Yucatán, algunas zonas del manglar han sido rellenadas con escombros y basura, donde posteriormente se establecieron zonas habitacionales.
Preguntas: ¿Puede usarse el conocimiento de la estructura forestal y el almacén de carbono para establecer la línea base para la conservación de los manglares urbanos?
Especies de estudio: Rhizophora mangle L., Laguncularia racemosa Gaertn f., Avicennia germinans L. y Conocarpus erectus L.
Sitio y años de estudio: Isla del Carmen, Campeche, año 2017.
Métodos: Se establecieron unidades de muestreo para evaluar la vegetación y medir el carbono aéreo y subterráneo en dos zonas de manglar, la primera fue rellenada con escombros y otra sin cambios del suelo.
Resultados: La zona rellenada con escombros presentó un área basal de 25.4 m2 ha-1, donde A. germinans fue la especie dominante con 675 árboles ha-1, con promedios de 5.5 m en altura y 13.4 cm de diámetro. La otra zona sin cambios del suelo presentó un área basal de 27.8 m2 ha-1, siendo también A. germinans la especie más abundante con 731 árboles ha-1, pero su altura fue más baja (5.0 m) y su diámetro a la altura del pecho mayor (15.2 cm) que en la otra zona. El carbono total almacenado en la segunda zona (383 Mg C ha-1) fue mayor que en la primera (321 Mg C ha-1).
Conclusiones: El valor ecológico de la vegetación y la captura de carbono contribuye en el fortalecimiento de medidas de conservación y protección del manglar ante las invasiones urbanas.

Por lo tanto, se estableció como objetivo el realizar un estudio de mercado que determine la pre-factibilidad técnica-económica de la implementación de una empresa productora y comercializadora de baldosas de cauchos, a través del procesamiento de neumáticos fuera de uso en el cantón Naranjito. Esto conllevo a determinar las probabilidades de éxito en la comercialización del producto, a través de un estudio de mercado, a establecer los recursos técnicos necesarios para la implementación de la empresa productora y comercializadora de baldosas de caucho y a realizar un estudio económico-financiero, a través de índices financieros que demuestren la vialidad del proyecto. La fundamentación teórica se la realizó en base a estudios o trabajos provenientes de revistas, artículos científicos tesis de pregrado entre otros. En cuanto a las técnicas de recolección de información requiere un estudio transversal y descriptivo, la población corresponde a la población económicamente activa por grupos ocupacionales del cantón Naranjito de acuerdo con el último censo población realizado por el Instituto Nacional de Estadísticas y Censos (INEC), la técnica utilizada fue la encuesta. Los resultados obtenidos permitieron conocer que las personas mantienen una frecuencia buena de compra de pisos o adoquines para las distintas necesidades del consumidor, entre ellos los distribuidores de esta clase de productos, el atributo que influye más en la selección de estos productos son los precios debido a que gran parte de los consumidores son distribuidores, otros se inclinan por la variedad de diseños, que es un aspecto importante para brindar variedad y un grupo prefiere las garantías del producto, entre otros aspectos que sumados con la viabilidad económica en la cual se realizó la descripción de los activos, los gastos, costos e ingresos que ayudaron a determinar la inversión total del proyecto, cabe mencionar que es estimó una proyección a cinco años, la inversión total fue de $432962.53, valor que será recuperado a inicios del último año proyectado, los indicadores financieros permitieron analizar el VAN el cual es positivo, el mismo que ascendió a $287149.23 y una TIR de 36% que supera la tasa de descuento (13%) demostrando que la empresa podrá cumplir con todas sus obligaciones, es decir, se cumple con la viabilidad de la propuesta. Esto conllevo a desarrollar los componentes tanto administrativos, operativos y técnicos para complementar la propuesta con el desarrollo de la filosofía corporativa de la empresa (misión, visión y valores), luego se especificará cada cargo de la empresa en un organigrama estructural seguido de la descripción de funciones, además se desarrolla la producción de bienes y finalmente la descripción del plan de estrategias, todo esto permitió establecer una propuesta sustentada que puede ser puesta en marcha en cualquier momento, aprovechando parte del mercado insatisfecho de las baldosas.

En este documento se presenta el estudio de la eficiencia de dos concentradores solares: un colector cilindro parabólico y un colector de disco con motor Stirling, los cuales permiten aprovechar la energía solar para obtener otro tipo de energía. Los combustibles fósiles han contribuido enormemente en la generación de energía en todo el planeta, pero a la vez han producido alta contaminación afectando el medio ambiente. Estos combustibles no son renovables y esto ha permitido emplear las energías renovables como una alternativa para la generación de energía eléctrica. La energía solar se convierte en térmica por medio de colectores que enfocan los rayos solares sobre un tubo en el cual, un fluido de trabajo se calienta y produce el calor. La electricidad se genera mediante el uso de paneles solares o utilizando el vapor para mover una turbina conectada a un generador de corriente. Debido a que la ciudad de Armenia, Colombia cuenta con un buen recurso solar, se realizó el diseño y montaje de un concentrador cilindro parabólico con un área de 1,0 m2, una distancia focal de 17 cm, aluminio como material reflector y agua como fluido de trabajo. Se realizaron pruebas semanales midiendo durante 6 meses los valores de las temperaturas de entrada y salida del tubo, la temperatura de salida del agua, la temperatura ambiente y la radiación solar. Se calculó la eficiencia térmica y óptica del colector. Adicionalmente se implementó un disco parabólico de 60 cm de diámetro con un motor Stirling pequeño. Las pruebas se realizaron semanalmente durante 5 meses midiendo la temperatura ambiente, temperatura en el reflector y en el absorbedor y se calculó la eficiencia del sistema. Para ambos colectores se desarrolló su respectivo sistema de seguimiento solar automático con el fin de obtener una mayor concentración de la radiación.

Diante do contexto atual, o aumento da produtividade, e a busca incansável para o aumento da receita, gerir um departamento de manutenção é enfrentar, diariamente, quebras e problemas inesperados. Os custos variáveis da operação e manutenção das máquinas, infelizmente, são proporcionais à idade destes. Considerando-se o fato de que a manutenção é essencial, demonstra-se, neste estudo, como é a escolha de uma linha de produção, para aplicação do conceito de TPM (Manutenção produtiva total), e exemplificação das medidas adotadas para atingir a zero perda. Este trabalho limita-se às etapas de planejamento, implantação e avalição dos resultados que foram alcançados com metodologia TPM.

Les projets sont réalisés dans le but de trouver des solutions à certains problèmes. Ainsi, plusieurs organisations et praticiens du management des projets portent leurs attentions sur la performance des projets. Depuis quelques années, le Cameroun s’est engagé dans la réalisation de grands chantiers de construction au Cameroun potentiellement assimilables à des mégaprojets. Il est donc bénéfique de s’interroger sur la performance de ces mégaprojets. L’objectif général de cette recherche était d’évaluer l’effet du savoir-faire des acteurs de la construction sur les performances des mégaprojets de construction au Cameroun. Cette étude a été réalisée particulièrement sur quatre mégaprojets de construction au Cameroun. Il s’agissait du projet de construction du second pont sur le fleuve Wouri, du projet de construction de la première phase de l’autoroute Yaoundé - Douala, du projet de construction du complexe sportif de Japoma et du projet de construction du barrage hydroélectrique de Nachtigal. Cette recherche a été une étude empirique de nature mixte. Les entretiens semi-directifs et les recherches documentaires ont été les principaux moyens de collecte des informations. Les données collectées ont été analysées et traiter à l’aide d’un logiciel d’analyse de données. A l’issue de cette recherche, il ressort que pour tous les mégaprojets étudiés, les délais d’exécution n’ont pas été respectés. Pour 75% de ces mégaprojets, les coûts initialement prévus ont été dépassés. En revanche, les exigences de qualité ont été respectées pour tous ces mégaprojets. Les savoir-faire tels que la formation, la préparation et les capacités managériales des acteurs influencent significativement les performances des mégaprojets de construction au Cameroun.

Au Sénégal, dans la frange Nord de la zone des Niayes, les applications des produits phytosanitaires des cultures maraichères sont essentiellement effectuées à partir de matériels de pulvérisation manuelle. Ces pratiques engendrent souvent des dérives au-delà de la zone cible, ce qui peut favoriser des affections liées à la toxicologie et à l’éco toxicologie des pesticides chez les êtres vivants et les organismes non cible dans la zone.L’objectif visé est de connaitre les risques liés aux effets de dérive des traitements phytosanitaires sur la santé humaine et sur l’environnement ainsi que l’efficacité de ces produits utilisés pour une meilleure optimisation de la production maraichère dans les Niayes du Sénégal.Pour ce faire, des enquêtes de terrain ont été menées auprès de 122 producteurs et ainsi que des essais expérimentaux en milieu paysan pour déterminer d’une part la perception de leurs pratiques phytosanitaires sur la santé et l’environnement et d’autre part les effets de dérive sur la population maraîchère et la biodiversité. L’étude a montré que : (i) les chenilles (Hélicoverpa armigera, Tuta absoluta…), les pucerons (Aphis sp), les aleurodes (Bémisia sp), les thrips (Mégalothrips sp) et la mouche des fruits (Cératitis sp) sont les arthropodes les plus présentes ; (ii) les matières actives les plus utilisées par les producteurs sont : le profénofos 53%, le diméthoate 9%, Acétamipride/Lambda-cyhalothrine 8%, abamectines 7%, Chlorpyriphos-méthyl 6% ,le chlorpyriphos-éthyl 5%, le Bacillus thuringiensis 4%, l’Emamectine benzoate 2%, le metamidophos 2%, le malathion 2%, le Dicofol 1% et le deltaméthrin 1% etc. ; (iii) la moyenne générale du nombre d’impacts des gouttelettes de dérive est comprise entre 69 et 102 d’impacts de gouttelettes par cm2 selon la distance de la zone de dérive ; (iv) la distance potentielle de dérive appliquée sur la culture de la tomate avec l’utilisation d’un pulvérisateur à dos manuel est de 6,875 m ; (v) les différentes formulations (Préfénofos, Diméthoate,Chlorpyriphos-éthyl) et dosages étudiés ne sont pas significatifs et même avec le témoin non traité. Néamoins il faut signaler que la formulation de la matière active Chlorpyriphos ethyl a un écart positif légèrement plus élevé que les autres et son comportement est constante pratiquement dans tous les sites. L’utilisation abusive, incontrôlée et les mauvaises pratiques ont fortement augmenté les risques de contamination des utilisateurs et la réduction de l’émergence arthropodes auxiliaires des cultures. De nouvelles mesures d’utilisation rationnelle, des bonnes pratiques doivent être étudiées et partagées avec les maraichers afin de réduire les effets de dérive.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español El presente documento pretende identificar, evaluar y mitigar los riesgos físicos y químicos del área de Laboratorio metalúrgico de la empresa EcuaCorriente S.A. aplicando la metodología NTP 330. Esta es una normativa española usada a nivel internacional para evaluar riesgos. Mediante normativas vigentes en Ecuador se pretende reconocer si las mediciones de los riesgos, se encuentran en estado bajo, medio o alto. También se desarrolla y se establece un programa de control de riesgos y del manejo de productos químicos, basándonos en normativas ecuatorianas como lo son las INEN. Como resultado del trabajo se encontró que en las diferentes sub-áreas de trabajo se midieron los riesgos físicos como ruido, iluminación y temperatura se encuentran cumpliendo todos los parámetros y especificaciones con absoluta normalidad, siendo adecuados los diferentes niveles, en el caso del ruido en el grupo de trabajo de Preparación de muestras, fue en donde se encontró los valores de ruido más altos (dB), gracias a esta medición higiénica se pudo determinar ello. En el caso de los riesgos químicos, el grupo de trabajo de la sub-área de análisis de muestras, mediante el monitoreo y la medición de los gases cumplen con los valores máximos permisibles, es importante recalcar que se midió Monóxido de Carbono (CO), Dióxido de Carbono (CO2), Hidróxido de Azufre (H2S) y Oxígeno (O2). Los resultados encontrados cumplen con los parámetros y los valores permisibles en la ley. Uno de los ideales de este trabajo es que se pretende erradicar o disminuir al máximo posible los riesgos en cada sub área del Laboratorio Metalúrgico.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español El presente proyecto de investigación tuvo como objetivo evaluar la efectividad de ocho productos mejoradores de adherencia (aditivos) en mezclas asfálticas de granulometría densa en caliente diseñadas bajo el Protocolo AMAAC a nivel II, con el fin de analizar y evaluar la efectividad diversos productos que se encuentran en el mercado y así diseñar carpetas asfálticas para pavimentos flexibles de alto desempeño eliminando los problemas de stripping o pérdida del recubrimiento causado por la presencia de agua en el interior de la mezcla y raveling o pérdida de agregados en la superficie de la mezcla causado por el paso de las llantas de los vehículos.Una vez seleccionados los ocho aditivos mejoradores de adherencia se procedió a aditivar un asfalto convencional AC-20 con cada producto y con dos dosificaciones 0.3% y 0.5% respecto al peso del asfalto, y se almacenaron en latas de aluminio de 10 litros. Los materiales evaluados son de origen calizo y de río, ya que por sus características físicas y químicas poseen una baja afinidad con el asfalto, es decir que las partículas de los pétreos tienen una baja adherencia con las partículas de los ligantes asfálticos.Para cumplir con los objetivos del proyecto se realizó la investigación en un laboratorio de mezclas asfálticas, evaluando en un primer momento el porcentaje de desprendimiento en mezclas sueltas con cada aditivo y en sus diversas dosificaciones, seleccionando el aditivo con mejores resultados. Posteriormente, con el asfalto aditivado seleccionado se realizó un diseño de mezcla de granulometría densa en caliente bajo Protocolo AMAAC a nivel II: caracterización de materiales, diseño volumétrico y se sometió a pruebas de alto desempeño TSR y Hamburgo.Los resultados obtenidos son presentados en la sección correspondiente con imágenes, tablas y gráficas comparando la efectividad del producto mejorador de adherencia. La confiabilidad del proyecto se obtuvo mediante pruebas de laboratorio normadas por la Asociación Mexicana del Asfalto A.C. (AMAAC), Sociedad Americana para Pruebas y Materiales (ASTM), La Asociación Americana de Oficiales de Carreteras Estatales y Transporte (AASHTO) y los equipos certificados y calibrados del laboratorio de mezclas de Ergon Asfaltos México.Como resultado de la investigación, se evidencia la existencia de materiales que se encuentran en diversas zonas de México con baja afinidad al asfalto, por lo cual es necesario buscar alternativas que sean factibles técnicamente, pero sobre todo económicamente, por lo cual una de las alternativas más socorridas por empresas contratistas en proyectos carreteros es la aditivación de asfaltos, mejorando las propiedades de los ligantes y por ende la calidad y periodo de vida de las carreteras.

(AMAAC), Sociedad Americana para Pruebas y Materiales (ASTM), La Asociación Americana de Oficiales de Carreteras Estatales y Transporte (AASHTO) y los equipos certificados y calibrados del laboratorio de mezclas de Ergon Asfaltos México.Como resultado de la investigación, se evidencia la existencia de materiales que se encuentran en diversas zonas de México con baja afinidad al asfalto, por lo cual es necesario buscar alternativas que sean factibles técnicamente, pero sobre todo económicamente, por lo cual una de las alternativas más socorridas por empresas contratistas en proyectos carreteros es la aditivación de asfaltos, mejorando las propiedades de los ligantes y por ende la calidad y periodo de vida de las carreteras.

El objetivo general de esta investigación es evaluar y validar diferentes plataformas digitales para encontrar la herramienta más pertinente en la transferencia de conocimientos a través del trabajo colaborativo para disminuir la reprobación y deserción en la carrera de Ingeniería de Software de la Universidad Politécnica de Santa Rosa Jáuregui. Realizada la evaluación y seleccionada la plataforma, se podrá proponer a ésta mejoras que la complementen. El problema de deserción que se ha venido reportando desde la primera generación en dicha carrera en el año de 2011 indica un índice de 37%. Esta cifra ha venido oscilando para tener un punto crítico en el año de 2015 con el 75%. Particularmente, en el área de programación de la carrera se tiene un índice de reprobación del 60% al 80% que al final se convierte en deserción. El problema científico que se plantea es la necesidad de ofrecer una herramienta en el contexto de las tecnologías de in-formación y comunicaciones que a través de un trabajo colaborativo permita que el alumno mejore su rendimiento académico mediante el uso de una plataforma digital. La investigación tiene un enfoque mixto; en ella se encuentran elementos cualitativos y cuantitativos. En cuanto a su finalidad, la investigación es exploratoria, descriptiva y correlacional. En ella, se comparan 2 plataformas digitales para determinar cuál de ellas mejora la transferencia de cono-cimientos a través del trabajo colaborativo y reduce la reprobación. Los resultados de este trabajo muestran que el Blog ofrece mejores resultados que el WhatsApp para disminuir la reprobación en la carrera de Ingeniería de Software impartida en la Universidad Politécnica de Santa Rosa Jáuregui. La plataforma digital del Blog representa la mejor alternativa como una plataforma digital que incide en el aprendizaje activo que disminuye la reprobación de los alumnos y mejora el rendimiento escolar.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español En la actualidad, en el distrito de Chinchao, no se cuenta con un relleno sanitario para la disposición adecuada de los residuos sólidos, la cantidad de residuos que a diario se generan solamente en la zona urbana, es de 4.096 Tn/día (MPCH, 2019), y todos estos residuos están siendo dispuestos en un solo botadero denominado botadero municipal de Acomayo, sin considerar los aspectos de tratamiento, segregación, reaprovechamiento y educación ambiental, elementos importantes para una verdadera Gestión Integral de Residuos Sólidos, conociendo dicha problemática, nos hemos propuesto realizar el presente trabajo de investigación, cuyo objetivo principal fue determinar el impacto ambiental generado por el botadero municipal de la ciudad de Acomayo.El diseño de la investigación es no experimental, de tipo descriptivo, correlacional y explicativa, con un enfoque cualitativo y de corte transversal. El método empleado en la investigación para realizar la evaluación de los impactos ambientales fue la matriz de causa efecto de Leopold, asimismo para realizar la categorización del botadero municipal se realizó mediante el modelo 1 y 2 para la categorización de botaderos planteados por CONAM y CEPIS/OPS, 2014. De los resultados obtenidos en la evaluación del impacto ambiental mediante la matriz de Leopold, tenemos que la agregación total de los impactos es de - 614, en la cual la mayor agregación de impactos se obtuvo con las acciones de acumulación de residuos sólidos con -114 y presencia de lixiviados con -123, asimismo se encontró que los factores ambientales más afectados, fueron la estructura y calidad del suelo con un valor de agregación de impactos de -100 y el aire con un valor de agregación de impactos de -94. Con respecto a la categorización del botadero municipal, utilizando la metodología 1 de categorización según prioridad de clausura, se obtuvo un valor de 23%, ubicándolo como un botadero de Riesgo Bajo, y la categorización mediante la metodología 2, según los impactos, se obtuvo un valor de 42%, ubicándolo como un botadero de Riesgo Moderado, por lo que amerita la conversión del actual botadero a un relleno sanitario.Los resultados obtenidos servirán para que las autoridades puedan tomar decisiones urgentes en el diseño de plan de manejo integral de residuos sólidos y la construcción de un relleno sanitario, así mismo la sensibilización de la población en contribuir con la protección del medio ambiente.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español A lo largo de la historia el ser humano ha necesitado conservar sus alimentos, principalmente la carne, para ello ha utilizado diversos aditivos para curar esta proteína, como es el caso del Nitrito de Sodio, el problema radica en que este aditivo está relacionado con aparición de algunos tipos de cáncer, por lo cual, se ha buscado una alternativa natural al Nitrito de Sodio.Con esto en mente, el objetivo es evaluar el posible uso de la pasta de achiote (Bixa orellana) en la industria alimentaria cárnica, como sustituto natural del Nitrito de Sodio, con ello se pretende contestar a la pregunta ¿es posible el uso de la pasta de achiote (Bixa orellana) en la industria alimentaria cárnica, como sustituto natural del Nitrito de Sodio? Para responder a esta pregunta, se realizará una investigación bibliográfica sobre diferentes estudios en los cuales se demuestren las propiedades colorantes, conservantes y antimicrobianas del achiote (Bixa orellana), de estas se extraerán las mediciones de CMI (Concentración Mínima Inhibitoria) y la CBM (Concentración Bactericida Mínima), posteriormente se creará una pasta de achiote (Bixa orellana) al 12,88% m/v de Ácido Acético, que se sometió a análisis con muestras que contenían Staphylococcus aureus y Escherichia coli, luego se compararon los datos para determinar si muestran consistencia como inhibidor bacteriano o bactericida.De acuerdo a estos resultados, se puede concluir:Según los datos de los estudios consultados y los datos obtenidos de los análisis de las muestras, el achiote tiene potencial en la industria alimentaria cárnica, pero, específicamente para la pasta de achiote creada y conservada en vinagre, se obtuvo una CMI de 1.49 g/mL y una CBM fue de 2.45 g/mL para aquellas muestras con presencia de Staphylococcus aureus, mientras que para las que tenían presencia de Escherichia coli, la CMI registrada fue de 1.59 g/mL y la CBM de 2.56 g/mL.La coloración y el sabor obtenidos mediante la pasta de achiote resultan ser muy similares o superiores a los obtenidos con Nitrito de Sodio, con la diferencia en que según (Araúz, 2020), el principal componente de las semillas de achiote es la Bixina, la cual es muy segura para el consumo humano, ya que estudios de toxicidad, en ratas, han demostrado que la bixina posee baja o nula toxicidad en ratas a las que se le administró 1 000 mg por kilogramo de peso corporal.Es por ello que se debe buscar un sustito seguro para el curado de las carnes, y todo apunta a que este puede ser la pasta de achiote.Con la utilización de la pasta de achiote como sustituto del Nitrito de Sodio como conservante y colorante, se lograría reactivar las economías de comunidades agrícolas de América Tropical, con lo cual el impacto de este cambio sería no solo a nivel de salud de los consumidores, sino que también, se impactaría positivamente en la economía, máxime en estos tiempos de pandemia, en los cuales es menester buscar formas de reactivar la economía.

En una sociedad globalizada, la ciberdelincuencia se ha vuelto un problema importante, generando riesgos de información indispensable, como contraseñas, datos personales, entre otros. Sin mencionar, las grandes sumas de dinero que los ataques cibernéticos logran alcanzar cada año. Esta situación ha tomado tal magnitud, que las medidas de seguridad convencionales no son suficientes para brindarnos seguridad en un entorno digital. Por tal motivo, surge la necesidad de implementar nuevas herramientas de protección informática, de las cuales han destacado los “Honeypots”. Estos últimos ha tomado relevancia, además de proteger, proporcionar seguridad; se consideran sistemas de tipo “trampa” que sirve para observar los diferentes comportamientos de ciberataques para posteriormente analizar la intrusión, los métodos que se utilizaron. El presente artículo pretende como objetivo general, el estudio del comportamiento activo de un Honeypot para posteriormente determinar su rendimiento, precisar su grado de eficiencia en la detección y clasificación de intrusos de ciberataques. Para tal propósito, se implementará una metodología tecnológica, integrada por cinco (5) Fases: diagnóstico, diseño de un plan, recursos, monitoreo y evaluación, tal como lo plantea Arias (2016). Se elaborará un estudio que implique el uso de un Honeypot con monitoreo constante en tres tipos de situaciones diferentes que simulen un ataque cibernético, en distintos grados de intensidad: sin ataques alguno, ataques inferiores a 5 ciclos por minutos (Ataques leves), ataques superiores a 10 ciclos por minutos (Ataques fuertes). Los resultados obtenidos son altamente aceptables; el honeypot obtuvo un 95% de eficiencia en la detección de ciber ataques simulados con un rendimiento de 95.4%.

Con el objetivo general de determinar las áreas con potencial de riesgo a contaminar las aguas subterráneas mediante un análisis multicriterio, con el fin de sentar las bases para el ordenamiento ecológico del territorio. El tema de investigación se aborda desde un enfoque determinístico, que se presenta en los estudios del territorio como una aproximación determinística cartográfica. La metodología implementada es de corte Mixta con un diseño de investigación explicativo perteneciente a la subcategoría cuasiexperimental. Como resultados y conclusiones generales de este estudio, se devela que los valores altos a extremos de riesgo se encuentran fuertemente correlacionados a: suelos degradados que son considerados inapropiados para la retención de vectores de contaminación; pendientes del terreno que van de 6-12 %; zonas no saturadas conformada por una litología de depósitos aluviales (arena y gravas) donde se han desarrollado asentamientos sin sistemas de alcantarillado y grandes extensiones de actividades agrícolas; se identifica como zona de interés por sus altos valores de riesgo a el valle de Iguala – Cocula. Por último, se logra establecer ocho líneas de gestión del territorio las cuales son: 1) Consolidación de asentamientos; 2) Mejoramiento de asentamientos; 3) Zonas de aprovechamiento sustentable; 4) Zonas restrictivas; 5) Zonas de restauración; 6) Zonas de conservación; 7) Zona de amortiguamiento minero; 8) Zonas de protección.

L’évaluation de son plateau technique médical permet de comprendre les relations qui existent entre les équipements biomédicaux appropriés utilisés par des ressources humaines qualifiées qui évoluent dans des infrastructures sanitaires adéquates selon un référentiel de base conçu. Ce dernier dénommé « NEONAT » est inspiré des normes et standards internationaux en l’adaptant au contexte de l’Afrique Subsaharienne. L’étude, menée dans les structures sanitaires du Sénégal entre 2021 et 2022, a adopté une méthodologie de recherche axée autour d’un système de notation des données collectées. Les scores obtenus ont révélé que les équipements constituent 41% du plateau technique médical de néonatologie tandis que les infrastructures occupent 29%. Par contre, les ressources humaines ont un poids égal à 31%. Par ailleurs, il en résulte que la pérennisation du parc matériel biomédical de néonatologie dépend de son entretien préventif et de sa maintenance curative. Etant donné que la technologie évolue de façon exponentielle, la mise à jour des connaissances des utilisateurs des exigences techniques de fonctionnement des équipements est primordiale. Elle permet de maîtriser les bases fondamentales afin de garantir une haute fiabilité des résultats obtenus et d’accroître la durée de vie de ces équipements. Le sondage sur les besoins de formation continue des acteurs concernés a révélé un taux de 100 %. Le niveau d’aptitude à la maintenance des utilisateurs est très faible et se chiffre à 23 %. Les équipements lourds occupent 60 % des pannes les plus fréquentes. Les technologies de l’information et de la communication liées au fonctionnement des équipements sont pratiquement méconnues. La proposition d’un modèle optimisé et l’élaboration d’un curriculum harmonisé de formation continue pour une prise en charge correcte des équipements biomédicaux destinés aux nouveau-nés permettent de contribuer dans la lutte contre la mortalité et la morbidité néo-natales.

Le sondage sur les besoins de formation continue des acteurs concernés a révélé un taux de 100 %. Le niveau d’aptitude à la maintenance des utilisateurs est très faible et se chiffre à 23 %. Les équipements lourds occupent 60 % des pannes les plus fréquentes. Les technologies de l’information et de la communication liées au fonctionnement des équipements sont pratiquement méconnues. La proposition d’un modèle optimisé et l’élaboration d’un curriculum harmonisé de formation continue pour une prise en charge correcte des équipements biomédicaux destinés aux nouveau-nés permettent de contribuer dans la lutte contre la mortalité et la morbidité néo-natales.

The development of biodegradable materials arises as an alternative to reduce the pollution caused by plastic waste to the environment, with this premise this study was proposed to develop plastic biopolymers from bioactive compounds with different matrices modified cassava starch (5 – 12 %), fish scale collagen (10 – 40 %), lemon essential oil (0,5 - 1,5 %) and gelatinization temperature (70 – 80 °C); A Box Behnken response surface experimental design was used; with the determination of their mechanical properties (maximum stress, Young's modulus, shear strength, stress at break and percentage elongation at break). According to the results found, it was determined that the modified cassava starch had the greatest influence on the mechanical properties, taking into account its importance to create more resistant materials, but it evidences plasticizing difficulties, where the fish scale collagen has a significant influence. In addition, it is evidenced that lemon essential oil had a great influence on Young's modulus (46,28 ± 2,31 MPa) and the percentage of elongation (69,69 ± 2,16 %); while the gelatinization temperature of 80 °C is not recommended for this type of starch-protein matrices due to damage of the structure; determining a better mechanical resistance and a great increase of Young's modulus. In conclusion, the characteristics and performance of the film based on cassava starch, collagen flakes and lemon essential oil have a positive impact on the maximum level of mechanical efficiency of the biodegradable films, achieving a better performance in their mechanical properties.

First, the compliance evaluation with the Sustainable Development Goals (SDGs) within the framework of the 2030 Agenda served to diagnose and determine, through fuzzy sets, a global sustainability index for the sample, resulting in a value of 0.638, in accordance with the overall average for the region. Probabilistic predictions were then made on the sustainability of the projects using a series of supervised learning classifiers (SVM, Random Forest, AdaBoost, KNN, etc.), with the SMOTE resampling technique, which provided a significant improvement toward the results of the different metrics of the base models. In this context, the Support Vector Machine (SVM) + SMOTE was the best classification algorithm, with accuracy of 0.92. Lastly, the extrapolation of this methodology is to be expected toward other realities and local circumstances, contributing to the fulfillment of the SDGs and the development of individual and collective capacities through the management and direction of projects.

En la investigación se analiza el comportamiento de la IED en América Latina y su disminución a partir del año 2012, situación que se agrava por la pandemia de la COVID - 19 a partir del año 2020. En este contexto se estudian los métodos tradicionales utilizados en América Latina para la evaluación de la inversión extranjera y se realiza una fundamentación teórica del método Multicriterio AHP, sus ventajas para la utilización en la toma de decisiones y al mismo tiempo se advierte que dicho método tiene una escasa experiencia de su utilización en la inversión extranjera en la región. Posteriormente se explica el proceso de negociación en el DR-CAFTA y el impacto de la inversión extranjera en la subregión que permite confirmar que el DR- CAFTA no ha contribuido al incremento del bienestar de la población de los países y en especial en República Dominicana. Si bien los resultados de la IED han sido desfavorables, los bajos montos de la inversión local son insuficientes y se necesita incrementar la IED para el desarrollo. Por esa razón, se hace necesario determinar a partir de los factores seleccionados a través del modelo multicriterio AHP, los países más atractivos para la IED y realizar las propuestas de política económica para que los países receptores sean más atractivos para esta inversión. La metodología de investigación es mixta, se utilizan métodos cuantitativo y cualitativo, los resultados esperados están relacionados con la determinación de los factores para la selección de los países más atractivos del DR-CAFTA para la IED a través del método AHP y la propuesta de las proyecciones para el incremento de la IED en la subregión. La hipótesis investigativa es que la estabilidad política, la libertad económica, las condiciones de riesgo y los niveles de corrupción son factores claves para la selección de los países más atractivos para la IED en el DR-CAFTA.

Ibero-american International University > Research > Articles and Books Cerrado Inglés Recently, the Internet of Medical Things (IoMT) could offload healthcare services to 5 G edge computing for low latency. However, some existing works assumed altruistic patients will sacrifice Quality of Service (QoS) for the global optimum. For priority-aware and deadline-sensitive healthcare, this sufficient and simplified assumption will undermine the engagement enthusiasm, i.e., unfairness. To address this issue, we propose a long-term proportional fairness-driven 5 G edge healthcare, i.e., FairHealth. First, we establish a long-term Nash bargaining game to model the service offloading, considering the stochastic demand and dynamic environment. We then design a Lyapunov-based proportional-fairness resource scheduling algorithm, which decouples the long-term fairness problem into single-slot sub-problems, realizing a trade-off between service stability and fairness. Moreover, we propose a block-coordinate descent method to iteratively solve non-convex fair sub-problems. Simulation results show that our scheme can improve 74.44% of the fairness index (i.e., Nash product), compared with the classic global time-optimal scheme.

Ibero-american International University > Research > Articles and books Abierto Inglés The rapid expansion of Internet of Things (IoT) devices deploys various sensors in different applications like homes, cities and offices. IoT applications depend upon the accuracy of sensor data. So, it is necessary to predict faults in the sensor and isolate their cause. A novel primitive technique named fall curve is presented in this paper which characterizes sensor faults. This technique identifies the faulty sensor and determines the correct working of the sensor. Different sources of sensor faults are explained in detail whereas various faults that occurred in sensor nodes available in IoT devices are also presented in tabular form. Fault prediction in digital and analog sensors along with methods of sensor fault prediction are described. There are several advantages and disadvantages of sensor fault prediction methods and the fall curve technique. So, some solutions are provided to overcome the limitations of the fall curve technique. In this paper, a bibliometric analysis is carried out to visually analyze 63 papers fetched from the Scopus database for the past five years. Its novelty is to predict a fault before its occurrence by looking at the fall curve. The sensing of current flow in devices is important to prevent a major loss. So, the fall curves of ACS712 current sensors configured on different devices are drawn for predicting faulty or non-faulty devices. The analysis result proved that if any of the current sensors gets faulty, then the fall curve will differ and the value will immediately drop to zero. Various evaluation metrics for fault prediction are also described in this paper. At last, this paper also addresses some possible open research issues which are important to deal with false IoT sensor data. Uppal, Mudita and Gupta, Deepali and Anand, Divya and S.

Renewable energy sources are integrated to maintain the demand of consumers, mitigate the active and reactive power losses, and maintain the voltage profile. Renewable energy sources are not supplied all day and, to meet the peak demand, extra electricity may be supplied through e-Vehicles. E-Vehicles with random integration may cause system unbalancing problems and need a solution. The objective of this paper is to integrate e-Vehicles with the grid as a backup source of energy through the grid-to-vehicle optimization approach by reducing active and reactive power losses and maintaining voltage profile. In this paper, three case studies are discussed: (i) integration of renewable energy sources alone; (ii) integration of e-Vehicles alone; (iii) integration of renewable energy sources and e-Vehicles in hybrid mode. The simulation results show the effectiveness of the integration and the active and reactive power losses are minimum when we used the third case.

Las opiniones de los expertos en gestión de proyectos son divergentes entre quienes se muestran escépticos sobre su vínculo con HRM y quienes sostienen que HRM es una palanca global para el éxito del proyecto. Este estudio tiene como objetivo enriquecer este debate centrándose en la existencia de un vínculo entre la gestión de recursos humanos y la gestión de proyectos PYME. La hipótesis general del estudio se basa en el principio de que las prácticas de GRH de las PYMES pueden traducirse en objetividad en los procedimientos de contratación, la relevancia de los sistemas retributivos, los rigores en las acciones formativas y el desarrollo de habilidades determinan los niveles de productividad organizacional. El diseño metodológico adoptado es la técnica de muestreo basada en deseos de administrar un cuestionario a una muestra de 87 partes interesadas en el estudio. Los resultados revelan que las prácticas de gestión de recursos humanos tienen vínculos significativos con la productividad de las pymes. Estos resultados podrían explicarse por las características específicas de la gestión de recursos humanos en las pymes. A modo de discusión, dado que se realizan pocos estudios sobre la gestión de proyectos PYME, ¿no deberían los futuros metodólogos dar protagonismo a la exploración de esta perspectiva de investigación?

La gestión de proyectos es una disciplina que influye en forma directa en el éxito o fracaso de cualquier proyecto, la industria del software no es la excepción. La currícula académica de las universidades se centra en brindar los conocimientos necesarios para que los estudiantes adquieran las competencias técnicas y metodológicas necesarias para lograr la correcta ejecución de un proyecto. Sin embargo, el énfasis en materias de gestión de proyectos, así como su práctica en proyectos reales presenta una dificultad adicional y por consiguiente una dedicación menor que el resto de las áreas de conocimiento. En este artículo se responde las siguientes preguntas de investigación: i) ¿Cuántas horas se dedican los estudiantes a la gestión de proyectos? y ii) ¿Las horas de gestión de proyectos se relacionan con la metodología aplicada? En este trabajo de investigación se utilizó un enfoque cuantitativo de carácter no experimental, donde se analizaron los datos provenientes de 349 proyectos de tesis de titulación universitaria de carreras de ciencias de la computación provenientes de dos universidades. Los proyectos analizados se centran en 3 metodologías de gestión: la propuesta por el Project Management Institute (PMI), una específica para proyectos de software y el framework SCRUM. Finalmente, en función de los resultados obtenidos se demuestra que en el contexto académico no existen diferencias considerables que relacionen el esfuerzo con la metodología aplicada y que el esfuerzo en tareas de gestión se ubica en el intervalo de entre 5% y 15% siendo consistente con la literatura presentada.

Ibero-american International University > Teaching > Master's Final Projects Cerrado Español La provincia de Santa Elena, es una de las más importantes del Ecuador, por sus diversos atractivos turísticos y sus hermosas playas. Se encuentra dividida políticamente en tres cantones que son La Libertad, Salinas y Santa Elena. Sin embargo, presenta una grave problemática ambiental que se relaciona con la mala disposición de sus residuos sólidos urbanos. Por tales motivos, se ha planteado una investigación desde el punto de vista económico, que busca verificar si se considera los costos de disposición final dentro de sus modelos financieros. Se planteó la hipótesis de que los municipios tienen botaderos a cielo abierto, debido a que solo costean las componentes de barrido y recolección sin considerar la disposición final. Dentro de los resultados se encontraron que: para el cantón Salinas, La Libertad y Santa Elena, el costo unitario de la gestión integral por tonelada es de $71, $69 y $ 51 dólares respectivamente. De estos totales, el costo unitario de la disposición final representa entre $ 3 y $ 4 dólares por tonelada. Del mismo modo, otro resultado importante son los elevados costos administrativos de los sistemas de aseo, debido a la burocracia en los municipios. Con estos resultados, se valida la hipótesis planteada y se evidencia que, dentro de los presupuestos municipales, no se considera los costos de disposición final y este es el motivo principal de que los sitios de disposición sean botaderos a cielo abierto. Por esta razón se plantea una solución que considera un relleno sanitario ubicado de forma técnica en el sector Ayamblo en Salinas, que va a permitir atender por 20 años a todos los cantones de la Provincia. Para ello, las municipalidades deberán presupuestar alrededor de $28 por tonelada para poder sostener todas las operaciones e inversiones en el nuevo relleno propuesto. Dentro de las principales conclusiones, se resalta el hecho de que no se considera los costos de la disposición final en los sistemas actuales de aseo. Además, los municipios poseen estructuras tarifarias obsoletas que no cubren los gastos operativos actuales y se traducen en subsidios elevados. La alternativa de un relleno sanitario provincial es la mejor solución desde el punto de visto técnico, que se apega a la realidad económica del país. Para poder mejorar los sistemas de aseo, se debe empezar garantizando una correcta disposición. Luego de esto se puede ir empezando paulatinamente la mejora en otras componentes. Finalmente se recomienda extrapolar el presente estudio a otras provincias del Ecuador. García Paredes, Augusto David garciaaugusto95@gmail.com

Ibero-american International University > Teaching > Final Master Projects Cerrado Español El objetivo de la presente investigación fue conocer la gestión pública en la ejecución de presupuesto del Gobierno Regional Huánuco, para la gestión de una propuesta que mejore el gasto público, para cuál se aplicó un estudio de tipo proyectivo, descriptivo y no experimental y de enfoque cuantitativo, con la técnica de la observación, así como los instrumentos de análisis de documentos y fichas de observación. La población de estudio fueron los proyectos de inversión en infraestructura de la Región Huánuco, y la muestra no probabilística de tipo intencional, donde se analizó las 10 obras de mayor envergadura y 384 beneficiarios de las obras en la Región Huánuco. Cuyos resultados responden al objetivo antes planteado, observando la gestión pública desde la percepción de los beneficiarios, encontrando que el 85% y 90% de la población que expuso una baja planificación y organización del gobierno regional de Huánuco con respecto a los proyectos de inversión y que abarca a las obras de infraestructura efectuadas en la Provincia de Ambo, Pillcomarca, Ciudad de Llata, Tingo María, Rupa Rupa y la Región de Huánuco, verificándose un incumplimiento en la ejecución de la obra y diferencias con respecto al monto programado y acumulado, desde los años 2012, 2016 al 2019. Asimismo, el porcentaje de ejecución presupuestal de las obras alcanza el 18.63% en la ampliación del sistema de agua potable e instalación del sistema de alcantarillado de la ciudad de Llata, provincia de Huamalíes - Huánuco, así como solo un 40.00% en la obra de mejoramiento de la capacidad resolutiva del hospital de Tingo María. En conclusión, estos hallazgos evidenciaron que la gestión pública tuvo una baja planificación y organización en la ejecución del presupuesto, por lo tanto, se verifica un incumplimiento en la ejecución y disparidad en los presupuestos programados. Por lo que se presentó, una propuesta de gestión pública para la Región Huánuco, con la finalidad de mejorar la eficiencia en la ejecución de la infraestructura que permita satisfacer oportunamente la demanda de la Región.

El Área Metropolitana de Misiones no cuenta con un adecuado tratamiento de residuos de construcción y demolición (RCD) por parte de los municipios que la integran, por lo que no alcanzan las bases del desarrollo sostenible. El objeto del artículo fue presentar un modelo para la cuantificación de RCD, desarrollando un caso de estudio correspondiente a la cimentación de 154 viviendas sociales ubicadas en el área de referencia mediante la aplicación del Método de Transferencias Ponderadas, la adopción de dicho método se basó en emplear distintas bases de costos de construcción y cuantificar los RCD que se espera generar en la obra, obteniendo la información de cada elemento, material del pliego y la planilla de cómputo, y el presupuesto del proyecto para luego organizarla según la codificación de la Lista Europea de Residuos. Finalmente, se aplicó el modelo matemático generado a partir del Método de Transferencias Ponderadas, lo que propicio convertir los recursos consumidos en volumen de residuos de hormigón, acero y tierra generados durante la cimentación de 154 viviendas sociales. Se concluyó que el modelo cumple las premisas del trabajo y que su aplicación permitirá apoyar la toma de decisiones respecto a la gestión de RCD.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español La medición de la conciencia ambiental es una tarea complicada debido a que es una variable compleja formada por dimensiones, subdimensiones e indicadores; sin embargo, constituye un primer paso para la toma de decisiones con respecto a la problemática ambiental que se presenta de manera global en el mundo, regionalmente cada país y específicamente cada área. Por lo tanto, en el estudio, se buscó determinar la relación del grado de conciencia ambiental con los factores socioeconómicos de los individuos de la población adulta del Distrito de Trujillo (La Libertad - Perú), a través de una metodología de investigación cualitativa, un diseño no experimental de tipo correlacional y un corte es transversal; optando por una muestra probabilística de la población de personas adultas, mayores de 18 años del Distrito de Trujillo. Asimismo, con ese objetivo, se diseñó un instrumento de medición, constituido por un cuestionario integrado por dos partes: una de datos generales de los individuos y la otra de 18 preguntas sobre conciencia ambiental; cumpliendo dicho instrumento con los requisitos de validez y confiabilidad para medir el grado de conciencia ambiental en una escala de puntaje de 0 a 90. Después, se recogieron y procesaron los datos generales con información relativa a los factores socioeconómicos (sexo, rango de edad, estrato socioeconómico y nivel educativo) de cada individuo, siendo analizada luego mediante las pruebas estadísticas: Kolmogorov - Smirnov para determinar la distribución normal de la muestra y ANOVA de un factor complementado por HSD de Tukey para determinar la diferencia entre los grupos de la población; observando que todos los grupos presentaban un grado medio de conciencia ambiental (> 36 puntos, < 54 puntos) y concluyendo que: primero, las medias del grado de conciencia ambiental de los grupos por sexo no son significativamente diferentes; luego, las medias del grado de conciencia ambiental de los grupos por rangos de edad son significativamente diferentes a excepción de grupos de rangos que son iguales; después, las medias del grado de conciencia ambiental de los grupos por estrato socioeconómico no son significativamente diferentes; y finalmente, las medias del grado de conciencia ambiental de los grupos por nivel de estudios son significativamente diferentes.

Sin embargo, algunas empresas por diferentes motivos, nunca optan por su implementación. El objetivo general de esta investigación es desarrollar una guía para la implementación de un sistema de gestión de calidad en la academia de baile Second Home Studio en Tarragona, España. La metodología utilizada se enfoca en la elaboración de un diagnóstico de la academia, así como la creación de una guía para implementar un sistema de gestión de calidad con base en las Normas ISO 9000, ISO 9001 e ISO 9004. El diagnóstico se efectuó por medio de la aplicación de preguntas abiertas para recopilar información general de la empresa, así como la aplicación de una encuesta de autoevaluación a los directores y una encuesta de satisfacción tipo Likert para los alumnos inscritos. El diagnóstico de la academia refleja que actualmente existe una muy buena percepción por parte de los directores, así como de los alumnos, con respecto al grado de calidad de los servicios brindados. Entre las principales fortalezas se encuentra la existencia de una estrategia y política empresarial, prácticas de liderazgo proactivo, gestión de recursos y una cultura de mejora continua. Adicionalmente, la ubicación de las instalaciones, el conocimiento de los profesores y las estrategias de comunicación de la academia, son puntos muy destacables. Por su parte, los aspectos negativos detectados en el diagnóstico que requieren de especial atención son la falta de enfoque y gestión de procesos, y la falta de seguimiento, medición y revisión de resultados en la organización. A su vez, existe una percepción por parte de los alumnos de la academia sobre el hecho de que tanto los horarios de las clases como el proceso para dar quejas o sugerencias en la organización podrían mejorar. La guía para implementar el sistema de gestión de calidad es suficiente para la academia considerando sus recursos y necesidades. Ésta posee 6 pasos los cuales tienen que ver con la estrategia y política, liderazgo proactivo, gestión de recursos, gestión de procesos, estrategia de seguimiento, y estrategia de mejora continua en la academia.

Uno de los principales objetivos para la sustentabilidad de un centro histórico es revitalizar las áreas patrimoniales, por contener estos elementos esenciales de la identidad local de cada ciudad. Su permanencia en el tiempo se garantiza a través de la restauración y recuperación de las edificaciones declaradas patrimoniales, evitando de esta manera su degradación potencial. La presente tesis doctoral se enfoca en realizar el estudio de identificación de materiales y técnicas constructivas tradicionales mediante el análisis realizado a morteros antiguos. Estos se seleccionaron en el convento de San Diego de la ciudad de Quito, y fueron estudiados en el laboratorio de química del INPC . Con los resultados obtenidos de cada muestra se determinaron sus componentes: cal, barro, paja de monte y el nopal. Este estudio también se enfocó en determinar la presencia o no de un aglutinante natural en los morteros, obteniendo como resultado la presencia del mucilago del nopal. Con estos elementos y valores obtenidos de los morteros antiguos, se procedió a diseñar las nuevas formulaciones. Se investigaron las características naturales de la cal, barro, paja de monte y mucilago de nopal. Por consiguiente, con estos resultados se diseñaron las nuevas dosificaciones. Su estudio y análisis se realizaron en el laboratorio de suelos de la PUCE . Para su experimentación se programaron los ensayos a los “14, 21 y 56 días” de edad de cada muestra, y con los resultados obtenidos en cada una de las pruebas mecánicas (compresión, tensión y flexión), se determinó cual es la más apta para su aplicación, garantizando su calidad y durabilidad. La investigación se complementa con el estudio realizado in situ. Con los datos obtenidos en el laboratorio, se replicaron las nuevas dosificaciones. La práctica se elaboró en la misma edificación de donde se obtuvieron las muestras de los morteros originales (convento de San Diego). El control de comportamiento de las muestras se efectuó: a los 7, 15, 30 y 45 días. Durante estos periodos se analizó su comportamiento frente a los cambios del medio ambiente. Con los resultados reales alcanzados y validados en los laboratorios, se ha verificado científicamente la recuperación de una dosificación que permitirá replicar los morteros con el uso de materiales y técnicas tradicionales para realizar una adecuada intervención.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés This paper focuses on retrieving plant leaf images based on different features that can be useful in the plant industry. Various images and their features can be used to identify the type of leaf and its disease. For this purpose, a well-organized computer-assisted plant image retrieval approach is required that can use a hybrid combination of the color and shape attributes of leaf images for plant disease identification and botanical gardening in the agriculture sector. In this research work, an innovative framework is proposed for the retrieval of leaf images that uses a hybrid combination of color and shape features to improve retrieval accuracy. For the color features, the Color Difference Histograms (CDH) descriptor is used while shape features are determined using the Saliency Structure Histogram (SSH) descriptor. To extract the various properties of leaves, Hue and Saturation Value (HSV) color space features and First Order Statistical Features (FOSF) features are computed in CDH and SSH descriptors, respectively. After that, the HSV and FOSF features of leaf images are concatenated. The concatenated features of database images are compared with the query image in terms of the Euclidean distance and a threshold value of Euclidean distance is taken for retrieval of images. The best results are obtained at the threshold value of 80% of the maximum Euclidean distance. The system’s effectiveness is also evaluated with different performance metrics like precision, recall, and F-measure, and their values come out to be respectively 1.00, 0.96, and 0.97, which is better than individual feature descriptors.

El objetivo de este estudio es determinar el Impacto Ambiental de la Concesión minera de áridos y pétreos “San Nicolás” sobre las comunidades de la ciudad de Cotacachi, con el propósito de establecer medidas de adaptación en la zona. Se determinaron los distintos impactos ambientales a través de un enfoque mixto, para el abordaje cualitativo se aplicó entrevistas semi estructuradas con ayuda del software Atlas. Ti, con la finalidad de determinar la frecuencia de cada una de las citas en relación con los entrevistados y se construyó un diagrama de relación entre citas y códigos, y así constatar la situación de la concesión minera; para el método cuantitativo se aplicó el diagnostico ambiental mismo que determina los factores bióticos, abióticos y socioeconómicos del área de estudio, esto se encuentra correlacionado con la aplicación de la matriz de Leopold, la cual se encuentra estructurada mediante una escala numérica obteniendo el carácter, intensidad, extensión, duración, reversibilidad y riesgo del impacto, donde se relacionó las determinantes obteniendo la magnitud, severidad e importancia del impacto, mismas que ayudó a determinar y solucionar los distintos impactos que se producen dentro de la concesión, finalmente se calificó la priorización de medidas de adaptación mediante la aplicación de la matriz tipo L. Los resultados indicaron las distintas afecciones que se generan dentro del lugar además de determinar el área de influencia directa e indirecta, se pudo constatar seis elementos sensibles dentro de la concesión: suelo, paisaje, aire, ruido, fauna y flora. Con el empleo de la matriz de magnitud e impacto, se obtiene la matriz de severidad que es la más importante obteniendo un total de 352 interacciones de las cuales 213 son de carácter leve, 55 moderado, 48 en estado crítico y 36 de impacto severo. Finalmente se analizó mediante el Software Atlas Ti, las entrevistas, obteniendo las acciones/o medidas de adaptación a implementarse dentro de la concesión minera San Nicolás, donde las más relevantes fueron: campaña de conciencia ambiental a todas las concesiones mineras, seguido de la siembra de plantas nativas y de soberanía alimentaria, y por último se destacó el mantenimiento continuo de cunetas y vías.

Ibero-american International University > Teaching > Master's Final Projects Cerrado Español En una planta de producción de cárnicos Int. Food Services Corp., que maneja materia prima en almacenamiento congelado y refrigerado; se han ajustado los procesos de congelación y descongelación, debido a novedades de clientes por desviaciones en la coloración de la carne y hueso. Según (Arteaga & Soto-Salanova, 2009) este fenómeno se conoce como síndrome de hueso negro y afecta en la decisión de adquisición del consumidor.Como parte del ajuste del proceso realizado en Int. Food Services Corp., en el 2020; en congelación se debe alcanzar una temperatura de ≤-18°C y en descongelación se debe emplear agua corrida. Estas variables han sido definidas con base en estudios previos realizados por la propia empresa; no obstante, el impacto del ajuste no ha sido valorado en almacenamiento por hasta 3 meses en el producto final (presas fritas). Por ello, el objetivo general del estudio es determinar la afectación de las características sensoriales en pollo frito en el color del hueso; con materia prima congelada en 0, 45 y 90 días de almacenamiento; para compararlo con el producto elaborado con materia prima refrigerada.Para esto se utiliza el colorímetro Minolta CR-400 como equipo de medición; mismo que (Konica Minolta, 2020) indica valora luminosidad (L*), que es el grado de oscurecimiento o blancura del hueso. Se considera medir en la tibia, debido a que las referencias bibliográficas indican que es la zona en la que mejor apreciación se tiene del defecto (Aingla, 2015). Como parte de la metodología se congela por cada jaba 90 presas, para posterior pasar a la descongelación, con una muestrea de 50 presas en cada tratamiento, y en pollo refrigerado se realiza la medición de luminosidad en 270 presas; en ambos casos se evalúa en pollo crudo y frito.Para la evaluación se ha revisado de manera bibliográfica pautas para valoración de síndrome de hueso negro y según lo reportado por (Mota, y otros, 2019) se emplea la siguiente escala: aceptable los valores superiores a 40L*, de riesgo alto o intermedio de 35 a 40L* e inaceptable los valores inferiores a 35L*. Se emplea para la estadística el programa de Minitab con un análisis varianza de un solo factor ANOVA con un nivel de significancia de 0,05 %, y con la prueba complementaria de Tukey para comparar los diferentes grupos. Los resultados indican que en el caso de hueso fresco el 100 % de las mediciones están sobre el rango de aceptable, pasando al rango intermedio únicamente en el 1 % de la muestra en fritura. Al comparar las medias de hueso crudo almacenado en diferentes tiempos, se determina que al día 90 existe diferencia significativa; pero en hueso frito no existe diferencia. Lo que indica que el tiempo de almacenamiento no impacta en el producto final y así pues en todos los casos las medias son superiores a 40L* (rango aceptable). Entonces, en cuanto a la hipótesis conceptual, se determina que el proceso estandarizado, genera un menor impacto en síndrome de hueso negro debido a que anteriormente los valores en hueso crudo congelado en el rango inferior estaban desde 29L* (coloración inaceptable) y ahora están sobre 40L* (coloración intermedia). Por otra parte, cada tratamiento térmico ha generado merma de luminosidad: en la descongelación de 3,85L* y en la fritura en producto refrigerado de 5.71L* y en hueso congelado de 6.74L*. Si bien el estudio genera un aporte en el control de síndrome de hueso negro, se recomienda generar nuevas evaluaciones conjuntas con el proveedor de materia prima.

Parkinson’s disease (PD) is a neurodegenerative disease that affects the neural, behavioral, and physiological systems of the brain. This disease is also known as tremor. The common symptoms of this disease are a slowness of movement known as ‘bradykinesia’, loss of automatic movements, speech/writing changes, and difficulty with walking at early stages. To solve these issues and to enhance the diagnostic process of PD, machine learning (ML) algorithms have been implemented for the categorization of subjective disease and healthy controls (HC) with comparable medical appearances. To provide a far-reaching outline of data modalities and artificial intelligence techniques that have been utilized in the analysis and diagnosis of PD, we conducted a literature analysis of research papers published up until 2022. A total of 112 research papers were included in this study, with an examination of their targets, data sources and different types of datasets, ML algorithms, and associated outcomes. The results showed that ML approaches and new biomarkers have a lot of promise for being used in clinical decision-making, resulting in a more systematic and informed diagnosis of PD. In this study, some major challenges were addressed along with a future recommendation

As indústrias automobilísticas brasileiras, para que se mantenham competitivas no mercado nacional e internacional, precisam lançar todos os anos novos produtos, personalizados as necessidades de seus clientes. Este cenário de mudanças contínuas nas características de seus produtos, influencia diretamente na configuração de seus almoxarifados, pois é necessária a alteração de insumos e peças, alterando características das embalagens armazenadas. Além disso, é comum que se tenham alterações mensais, ou mesmo quinzenais, em volumes de produção planejados, resultando em grande variação nos volumes necessários de estoques. De forma a suprir a necessidade dessas áreas de armazenamento, as indústrias tendem a realizar a locação de galpões externos, gerando aumento significativo de custo indireto de produção e impactando em seus resultados, como custos com aluguel, transporte, tempo e dificuldade no gerenciamento do abastecimento das linhas de produção (perda produtiva). A justificativa de preferir ter essa despesa de locação ao invés do investimento na implantação de um novo almoxarifado, acontece principalmente devido aos altos investimentos necessários e a consequente insatisfatória relação custo-benefício. Ao mesmo tempo, reduzir esse investimento é complexo, pois a Construção Civil é um setor que não conta com profissionais especialistas em inovação ou com motivação em fazê-la. A metodologia utilizada para a pesquisa, com enfoque quase experimental, será a análise de caso real de implantação de almoxarifado para indústria automobilística localizada na cidade de Sete Lagoas, Minas Gerais - Brasil, evidenciando os ganhos alcançados devido a eficaz direção do projeto. O resultado da pesquisa apresentará, após uma série de comparações entre tecnologias, inclusive seus custos de implantação, proposta de implantação de almoxarifado com menor custo de execução por metro quadrado, se comparada com as tecnologias tradicionalmente usadas, gerando melhor custo-benefício e demonstrará como uma eficiente gestão do projeto contribuiu para alcançar os objetivos e metas dessa empresa, proporcionando a ela menores investimentos, reduzindo seu custo operacional e melhorando sua produtividade e competitividade no mercado.

El tema investigado consistió en la implementación de un sistema medioambiental en una empresa ferroviaria de carga en la Argentina. La Empresa cuenta con la concesión de un tramo de 3145 km de vía desde 1992. Al transitar por más de 3000 km incluyendo comunidades y terrenos desérticos hace que la operación necesite contemplar el impacto a los distintos stakeholders en todas sus esferas de la sustentabilidad (medioambiental, social y económica). La Empresa poseía acciones aisladas respetuosas con el medio ambiente pero un Sistema de Gestión Ambiental basado en la norma ISO 14001 le facilitó a la organización obtener de las actividades que puedan causar algún impacto sobre el medio ambiente, además de ayudar a minimizarlos. El objetivo general, por lo tanto, constó de diseñar y aplicar un sistema de medio ambiental en una empresa ferroviaria de carga en Argentina, basado en los requisitos establecidos en las Normas ISO 14001, con la finalidad de alcanzar la certificación del sistema. La metodología utilizada fue la de análisis mixto (cuantitativo y cualitativo) mediante recorrida y entrevistas informales con el personal involucrado en tareas claves, también influyó mucho la observación en el campo. Los principales resultados fueron el logro del ordenamiento de las acciones, el control de la documentación y la certificación del sistema ISO 14001. Finalmente se elaboró un sistema de indicadores para evaluar el desempeño en Medio Ambiente mediante una mejora continua en la empresa. Debido a la demanda de la sociedad y requisitos legales que debe cumplir la empresa para poder operar como una empresa sustentable, obtener la certificación le sirvió para: cumplir con estándares internacionales, satisfacer expectativas de clientes que exportan sus productos, obtener un mayor puntaje de riesgo ambiental en la contratación de un seguro, mantener actualizada a la empresa con todos los cambios en la gestión, la minimización de residuos, el ahorro energético y la protección de su reputación frente a posibles inversores, clientes y sociedad en general.

Uno de los grandes problemas medioambientales de la eutrofización, es la presencia de grandes extensiones de malezas acuáticas en embalses como el lirio acuático. La presencia de esta planta acuática causa problemas eco-nómicos como la afectación al turismo y ambientales como la pérdida de especies. Se han implementado diversas formas de mitigar el problema, pero hasta ahora ha sido infructuoso. El presente trabajo de investigación explora la posibilidad de dar un posible uso al lirio acuático, mediante el desarrollo de un prototipo de reactor pirolítico solar con un alcance de temperatura de operación de 170 a 230 ºC, mediante el despliegue de ciclos de vida de proyectos y la irradiancia recibida en Jalisco. Se aplicó la gestión de proyectos en sus procesos de inicio, planificación, ejecución, monitoreo y cierre. En los procesos de inicio, se partió de un diseño conceptual donde un colector captó la radiación asumiendo una irradiancia de 1000 W/m2 y por cálculos de transferencia de calor por radiación, convección y conducción se estimó la temperatura en la cámara del reactor. Los procesos de planificación, ejecución y monitoreo se utilizaron para desarrollar el prototipo y los de cierre para validar su funciona-miento mediante mediciones de temperatura e irradiancia solar. El prototipo de reactor solar aportó evidencia sobre su capacidad para alcanzar una tempera-tura promedio de alrededor de 190 ºC en estado estacionario con una irradiancia media de 1260 W/m2 en otoño, asimismo se determinaron impactos negativos compatibles. Se realizaron pruebas para someter a pirólisis, muestras de lirio acuático (17-23 % de humedad) en vacío de 5 in Hg, para la producción de bio-carbón encontrándose que su optimización es influenciada por una temperatura mínima de operación (170 ºC) y tiempo de residencia (171.8 minutos). Este biocarbón fue caracterizado en base seca, resultando en 17.56 MJ/kg de poder calorífico superior, 20.11 % de carbón fijo y 6.89 de relación C/H (car-bono-hidrógeno). Como resultado, se cuenta con un nuevo reactor pirolítico solar, que puede procesar el lirio acuático para producir biocarbón con alto poder calorífico o como un medio para fijar el carbono, que contribuye al desarrollo sustentable desde lo local.

Ibero-american International University > Research > Articles and Books Abierto Inglés Energy is a crucial element for human needs today. Traditional systems of energy generation have represented a problem in terms of their costs, their impact on the environment, and their impact on community life. Therefore, the search for clean and renewable energy sources that meet the needs of contemporary society becomes increasingly essential in the search for alternatives related to energy sources. The photovoltaic energy generation system explores the solar irradiation, making it possible to generate and store energy. This system finds good conditions for implementation in Brazil in terms of climatic characteristics, but investments and public policies that encourage and favor this process are still needed. This study aimed to identify how the deployment of photovoltaic mini-generation power plant in a federal university, the Federal University of Paraná (UFPR), can contribute to the university community in relation to cost reduction and environmental preservation. The methodology used was descriptive-exploratory, qualitative, through which an open questionnaire and a semi-structured interview were carried out, guided by the theme. After analyzing the data, the conclusion was that the system can bring benefits in the long term and that most of the interviewees consider Brazil's great potential in expanding the exploration of other sources of energy, besides hydroelectric, which, besides being costly, brings fewer advantages related to the environmental and social contexts.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés In December 2019, a group of people in Wuhan city of Hubei province of China were found to be affected by an infection called dark etiology pneumonia. The outbreak of this pneumonia infection was declared a deadly disease by the China Center for Disease Control and Prevention on January 9, 2020, named Novel Coronavirus 2019 (nCoV-2019). This nCoV-2019 is now known as COVID-19. There is a big list of infections of this coronavirus which is present in the form of a big family. This virus can cause several diseases that usually develop with a serious problem. According to the World Health Organization (WHO), 2019-nCoV has been placed as the modern generation of Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) coronaviruses, so COVID-19 can repeatedly change its internal genome structure to extend its existence. Understanding and accurately predicting the mutational properties of the genome structure of COVID-19 can form a good leadership role in preventing and fighting against coronavirus. In this research paper, an analytical approach has been presented which is based on the k-means cluster technique of machine learning to find the clusters over the mutational properties of the COVID-19 viruses’ complete genome. This method would be able to act as a promising tool to monitor and track pathogenic infections in their stable and local genetics/hereditary varieties.

Mold breakout is one of the significant problems in a continuous casting machine (caster). It represents one of the key areas within the steel production facilities of a steel plant. A breakout event on a caster will always cause safety hazards, high repair costs, loss of production, and shutdown of the caster for a short while. In this paper, a logic-judgment-based mold breakout prediction system has been developed for a continuous casting machine. This system developed new algorithms to detect the different sticker behaviors. With more algorithms running, each algorithm is more specialized in the other behaviors of stickers. This new logic-based breakout prediction system (BOPS) not only detects sticker breakouts but also detects breakouts that takes place due to variations in casting speed, mold level fluctuation, and taper/mold problems. This system also finds the exact location of the breakout in the mold and reduces the number of false alarms. The task of the system is to recognize a sticker and prevent a breakout. Moreover, the breakout prediction system uses an online thermal map of the mold for process visualization and assisting breakout prediction. This is done by alerting the operating staff or automatically reducing the cast speed according to the location of alarmed thermocouples, the type of steel, the tundish temperature, and the size of the cold slab width. By applying the proposed model in an actual steel plant, field application results show that it could timely detect all 13 breakouts with a detection ratio of 100%, and the frequency of false alarms was less than 0.056% times/heat. It has the additional advantage of not needing a lot of learning data, as most neural networks do. Thus, this new logical BOPS system should not only detect the sticker breakouts but also detect breakouts taking place due to variations in casting speed and mold level fluctuation.

Cuenta con una población aproximada de 2296 habitantes, de acuerdo al último censo oficial realizado en el año 2010. Tiene una extensión cercana a las 64 hectáreas. Debido a las precipitaciones pluviales se han podido observar inundaciones dentro de la planta urbana, específicamente en la esquina que conforman las calles Hipólito Yrigoyen y Rocamora. Dichas precipitaciones ocasionan problemas a la población en distintos aspectos, que deben ser atendidos.Se pretende conocer las causas de las inundaciones en la zona urbana de la ciudad y responder a la interrogante de por qué hay sectores que se inundan luego de jornadas de lluvias intensas. Se evaluará la infraestructura pluvial existente mediante relevamientos planialtimétricos detallando características esenciales. Se identificarán las zonas más comprometidas realizando un análisis de la dinámica de escurrimiento hídrico que determine el camino de los flujos y sus confluencias. Se llevará a cabo un análisis hidrológico utilizando antecedentes de eventos pluviométricos importantes combinados con métodos propios de la hidrología para poder obtener las tormentas que provocan dichos episodios. Finalmente se calcularán los caudales admisibles de la infraestructura existente y se los contrastará con los caudales que genera la tormenta de diseño utilizada.

The proposed design employs ultrasonic sensors for obstacle detection, a water sensor for sensing the puddles and wet surfaces in the user’s path, and a high-definition video camera integrated with object recognition. Furthermore, the user is signaled about various hindrances and objects using voice feedback through earphones after accurately detecting and identifying objects. The proposed smart stick has two modes; one uses ultrasonic sensors for detection and feedback through vibration motors to inform about the direction of the obstacle, and the second mode is the detection and recognition of obstacles and providing voice feedback. The proposed system allows for switching between the two modes depending on the environment and personal preference. Moreover, the latitude/longitude values of the user are captured and uploaded to the IoT platform for effective tracking via global positioning system (GPS)/global system for mobile communication (GSM) modules, which enable the live location of the user/stick to be monitored on the IoT dashboard. A panic button is also provided for emergency assistance by generating a request signal in the form of an SMS containing a Google maps link generated with latitude and longitude coordinates and sent through an IoT-enabled environment. The smart stick has been designed to be lightweight, waterproof, size adjustable, and has long battery life.

The economic valuation of coastal ecosystem services is a critical step for the design of sound public policies that support the preservation of the services that nature provides to society in the context of climate change. Using the value transfer method, we obtained the economic valuation that represents the loss of coastal ecosystem services caused by sea level rise in Mexico. Using the Bathtub method, digital elevation models and sea level data, we identified the areas in the country prone to flooding and the associated ecosystem impacts. In Mexico, the annual economic loss caused by the disappearance of coastal ecosystem services is estimated at $6,476,402,405 USD, where wetlands represent the greatest economic losses, since they represent the largest affected ecosystem by area. However, beaches and dunes are the most valued ecosystem due to the economic activities that occur in these areas. In the mangroves, the service as habitat, refuge and nursery is the most valued for its positive relationship with fisheries. The states with the most economic losses are Baja California Sur, Sinaloa and Campeche. The protection of the coastal zone in Mexico should be a priority in the development strategies in the country because its loss and/or rehabilitation imply high economic costs and compromises the wellbeing of society.

Para realizar la prueba de esta metodología, se planteó el apoyo de la empresa Uniccall S.R.L. para la implementación y su correspondiente validación de la hipótesis planteada, se implementará el modelo a un sistema de gestión de la calidad ya implementado, en la empresa Uniccall S.R.L.El objetivo es el diseñar una metodología de seguridad informática para el aseguramiento de cumplimiento de los objetivos de control definidos en la norma NB/ISO/IEC 27001:2013 y un Sistema de Gestión de Seguridad de la Información implementado en la empresa de telecomunicaciones Uniccall S.R.L. Para definir las dimensiones que serán cubiertas por la metodología, se tuvo que realizar un estudio de la normativa boliviana NB/ISO/IEC 27001, definir claramente los dominios de control, objetivos de control, responsabilidades y también un análisis de riesgos para determinar los umbrales de aceptabilidad asociados a cada control del sistema de gestión de seguridad de la información implementado.Una vez realizada la implementación de la metodología propuesta, se realizó una medición del desempeño actual del sistema de gestión de seguridad de la información hasta el tercer trimestre de la gestión 2021, capturando la medición de indicadores por cada objetivo de control definido. Por otro lado, se analizó el resultado del análisis de riesgos para ajustar la periodicidad de los controles implementados ajustados al comportamiento de la institución. Como resultado, se logró mejorar la eficiencia de los controles de seguridad de la información en un 55%, logrando mejorar el desempeño y vigencia del SGSI implementado, integrando el componente de control como herramienta de gestión y monitoreo.La presente metodología se acopla al concepto de mejora contínua una vez que el ajuste de variables respetando el análisis de riesgos en la institución, logra una sostenibilidad en la vigencia de un SGSI implementado que puede tener recursos variables en el tiempo.

Las microempresas presentan bajos niveles de supervivencia tendiendo a desaparecer de manera acelerada a más de la mitad en tan solo el quinto año de vida; situación preocupante, si se tiene en cuenta que representan casi el total de las empresas en el mundo, y la mayoría de los empleos, alcanzando cerca del 50% del PIB mundial; convirtiéndolas en el eje central de la economía global, y en un actor fundamental en la reducción de pobreza y el fomento del desarrollo sostenible del planeta. La causalidad de esta situación puede verse disminuida con el uso de la Inteligencia Competitiva (IC), ya que en la actualidad, la supervivencia de los negocios no depende de cuál es el más fuerte, si no del que mejor y más rápido se adapte a los cambios en los mercados como los generados en la actual pandemia por la Covid19. Es así, que el presente estudio de enfoque cuantitativo, a la luz de sus hipótesis, la literatura y estudios previos sobre modelos de Inteligencia Competitiva en microempresas, describe la concordancia de los resultados recolectados, con el estado del arte actual; aportando información estadística sobre el conocimiento, actitudes y prácticas de IC en los microempresarios del departamento de Santander ubicado al nororiente de Colombia, con la cual, se construyó una propuesta metodológica de uso practico de IC para el fomento de la supervivencia microempresarial en la Región, que también puede ser punto de partida para estudios en otras zonas del país o del mundo desarrollados por entes gubernamentales, no gubernamentales, el sector productivo, la academia, los nuevos y actuales empresarios y la sociedad en general

Pese a que este sistema es de gran utilidad, también hay que considerar que enfrentan una alta posibilidad de ataques informáticos y muy expuestos a diversos riesgos.Los riesgos se encuentran en todo ámbito laboral y si no se detectan a tiempo ni se controlan de forma correcta, pueden llegar a ocasionar innumerables pérdidas en la entidad donde se han presentado; afortunadamente existen metodologías, como la Gestión de Riesgos Tecnológicos que tienen como objetivo principal, proteger la información, mediante el análisis y detección de las fortalezas y debilidades durante la prestación de servicios de la entidad.Para poder detectar a tiempo los riesgos a los que se encuentra expuesta una entidad y plantear los pasos a seguir para que la misma pueda salir bien librada de la situación de riesgo presente, existe la gestión de riesgos que es un conjunto de procesos planteados que permitirán abordar con eficacia la problemática a la que se encuentre expuesta la empresa en su determinado momento; a continuación, se presenta una Metodología de Gestión de Riesgos de TI, que permitirá darle un enfoque más directo a las entidades que prestan software como servicio en Ecuador, sobre cuán importante es asegurar sus procesos sistemáticos, que permitan sobrellevar eventos externos o propios, que se puedan generar en algún momento. Cuando nos referimos a seguridad, hacemos énfasis en que seguridad en informática, es la debida protección que se le da a los datos y su forma de resistir ante el inconveniente que se pueda generar, tal como menciona (Interpolados, 2020) en su sitio web.Por tal razón, se ha percibido la necesidad de plantear un análisis de riesgo tecnológico de orden cualitativo, teniendo como referencia a la empresa W&G Computer, siguiendo la metodología MAGERIT. Primero se procede a relatar la situación actual de la institución, luego a identificar los activos con sus amenazas, para de ahí calcular los riesgos existentes y lograr incorporar los procedimientos que se adapten perfectamente a la metodología que se va a proponer.En este proyecto han tomado protagonismo las reglas y normas relevantes que ayuden a establecer la seguridad de los datos de respaldo de la empresa para mitigar los riesgos y reducir las vulnerabilidades en los activos de la empresa. Los procesos dentro de la planificación juegan un papel indispensable ya que cada uno de ellos en sus diversas etapas de gestión de riesgos, deben dar confiabilidad de que el negocio pese a las interrupciones a las que se pueda someter al enfrentarse a un riesgo inesperado puede retomar su actividad sin que afecte tanto a su estabilidad económica. Para la valoración se ha estimado la herramienta PILAR, la cual soporta el análisis y gestión de los riesgos de sistemas de información siguiendo la metodología MAGERIT que permitirá obtener un modelo sistemático para examinar los peligros que se pueden presentar al manejar TIC. Para poder hacer un estudio a fondo de los riesgos que se puedan presentar a nivel de seguridad informática, se hará uso de la herramienta PILAR, ya que se estima como un software de alta calidad a nivel de seguridad informática que sirve para detectar y estudiar los riesgos a fin de estar precavidos ante su aparición imprevista, así como manifiesta (Ayudaley, 2019) en su artículo web. PILAR, permite realizar una investigación más profunda de los tiempos de respuesta y durabilidad de la entidad, los procedimientos que se han seguido y la forma en que los miembros de la empresa han reaccionado frente a una amenaza, todo esto siempre en función a la continuidad del negocio.Finalmente, la contribución de este proyecto es detectar e identificar el nivel de riesgo en que están los activos a través de la medición del nivel de madurez y eficacia de la seguridad implementada dentro de la institución.

Los actuales proyectos de construcción complejos y con altos niveles de cambios, requieren metodologías innovadoras enfocadas a orientar y mejorar las habilidades de los profesionales que los dirigen. Por esto, esta investigación tiene como metas incorporar los beneficios de aplicar técnicas ágiles en la metodología tradicional para la dirección de proyectos de construcción en Panamá y estandarizar su aplicación para optimizar sus resultados finales. Se utilizaron los métodos inductivo, cuantitativo y cualitativo. Mediante el análisis de contenido se analizaron normas, revistas y estándares de dirección de proyectos, información fiable para crear nuevo conocimiento. Para recolectar y vincular datos cualitativamente se utilizó el cuestionario aplicado a los profesionales de la dirección de proyectos y la construcción de Panamá desde el 2020 al 2021, su análisis cuantitativo se realizó mediante el programa estadístico SPSS. La Técnica Delphi validó la Metodología Híbrida, con expertos escogidos por sus competencias y experiencia. El 79% de los directores de proyectos aplican una metodología de dirección de proyectos, siendo las tradicionales las más usadas. Estos coinciden en que el factor tiempo es el objetivo de cumplimiento más problemático y que los factores externos afectan los resultados del proyecto (equipo, liderazgo, plataformas, herramientas y tecnologías, comunicación, objetivos claros). Se validó que en el sector económico de la construcción es apropiado aplicar la metodología híbrida de dirección con un resultado de 3.903, siendo 4 “muy apropiado”. Esta investigación evidenció que las metodologías de dirección de proyectos tradicional-ágil son complementarias, que al estandarizar los procesos tradicionales con métodos ágiles basados en las características propias de cada proyecto, se mejoran los resultados, cumpliendo con los objetivos del proyecto y los involucrados

Esto, desde la perspectiva de aplicaciones prácticas, permite contar con múltiples modelos de trabajo, sin embargo, el instrumento finalizador y posibilitador que la conceptualización del estándar, sea llevado a la práctica, aun no existe. Este instrumento es la “metodología” (Montes-Guerra, Gimena Ramos, & Diez-Silva, 2013).Este proyecto de investigación, de carácter proyectiva, es motivado por la necesidad identificada a partir de un análisis situacional, para establecer, una metodología de gestionan de proyectos acordes con las necesidades y particularidades de una organización. Partiendo del hecho que el gestionar proyectos, es una de las herramientas fundamentales para el logro de sus objetivos estratégicos. Por ello nuestro objetivo general es el de mejorar el nivel de madurez en gestión de proyectos de una organización dedicada a la operación y mantenimiento de un sistema de transporte de hidrocarburos, mediante el establecimiento de una metodología basada en el estándar PMBOK del PMI. Metodológicamente, el diseño de la presente investigación es de carácter no experimental, transversal o transeccional, de campo, observando la realidad tal como se presenta dentro de su contexto natural, en un determinado momento. Los resultados obtenidos, hacen notar que la organización muestra carencia de un marco adecuado para la gestión de proyectos. Asimismo, el nivel de conocimiento de un estándar internacional de gestión de proyectos y las competencias respecto de él, muestran niveles relativamente bajos. Las capacidades organizacionales identificadas y que se desenvuelven alrededor de la buena disposición que tiene la organización para combinar las habilidades, aptitudes y recursos, fundan las bases para la implementación de una metodología.

Subjects > Social Sciences Ibero-american International University > Research > Doctoral Thesis Cerrado Español Las afectaciones en las viviendas tradicionales ocasionadas por eventos extremos de origen natural como sequías e inundaciones en la provincia del Gran Chaco en Bolivia son frecuentes. En ellas inciden las técnicas de construcción usadas, los materiales de construcción empleados, la localización y el diseño de las viviendas, porque no resisten a las amenazas de dichos eventos extremos. Estos aspectos comprometen el hábitat de las poblaciones que las ocupan, como es el caso del pueblo originario Weenhayek. Es por ello que esta investigación propone desarrollar un modelo de adaptación al cambio cli-mático en las viviendas tradicionales en la provincia del Gran Chaco en Bolivia como alternativa para la mejora del hábitat humano de dicho pueblo. Para ello desde las bases teóricas de la adaptación planificada como componente de la resiliencia urbano-territorial, busca contribuir a la mejora de los sistemas socio ambientales ante los efectos del cambio climático a través de dichas viviendas tradicionales. Es desde la investiga-ción cualitativa que se apoya esta pesquisa para reconocer variables y atributos apoyados desde los enfoques interdisciplinar y sistémico. Los mismos permiten dinamizar y desarrollar dicho modelo, conectando las afectaciones climáticas y las viviendas tradicionales. Esto permite el establecimiento de un modelo para las viviendas tradicionales del pueblo Weenhayek adaptadas al cambio climático en la provincia del Gran Chaco en Bolivia, que ayuden a la preservación de sus rasgos sociales, culturales y constructivos. Puede contribuir además desde la práctica social a la mejora de las regulaciones territoriales en el ámbito rural, así como a la construcción de políticas públicas desde el ente regulador correspondiente. De esta manera el modelo de adaptación enfocado en las viviendas tradicionales Weenhayek puede significar una mejora de estas ante los efectos de los riesgos hidrometeorológicos extremos en dicha área.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español La investigación permitió brindar información a la empresa sobre el manejo, desarrollo y mejoramiento del sistema de gestión de clientes conforme a sus necesidades organizacionales. Todo ello, en un mercado donde cada día son menos rentables las metodologías conducentes a clientes masivos motivado a la demanda de servicios casi personalizado. El objetivo general, consistió en proponer un modelo estratégico de las 6R sobre la atención al cliente post pandemia en la empresa Roggero Autopartes y Servicios E.I.R.L., Lima 2021. Teóricamente se fundamentó en el Modelo 6R de gestión de relación con los clientes, la atención al cliente y el marketing relacional. Se desarrolló bajo un diseño no experimental, transversal con alcance descriptivo. Para la recolección de los datos se aplicaron tres cuestionarios; uno a los trabajadores de la empresa, otro a los clientes actuales y el último, a los clientes potenciales. Asimismo, la información sobre los competidores se recolectó mediante una guía de observación. Los resultados obtenidos muestran que la empresa debe considerar la diferenciación, conocimiento de las necesidades y expectativas de los clientes, flexibilidad y mejora continua, orientación al trabajo y al cliente, plantearse como meta la atención al cliente, la fidelización y la utilización de los canales digitales. Se concluye que, luego de la pandemia, el cliente de la empresa Roggero es quien dirige y controla la conversación que mantiene con el vendedor. Esto es debido a que, en la actualidad, los clientes poseen un celular con internet donde pueden consultar y buscar información acerca del producto que desean comprar y tomar la decisión que más les convenga.

Ibero-american International University > Teaching > Master's Final Projects Cerrado Español La gestión pública ha tenido un desarrollo evolutivo en las instituciones que buscan satisfacer las necesidades del colectivo. Por lo cual, es necesario un aseguramiento integral, el cual permitirá implementar un plan estratégico de gestión de riesgos que les otorgue herramientas para controlar el desarrollo y funcionamiento de los procesos. Un modelo estratégico es una herramienta que permite la eficiencia y productividad de la institución, por lo que, para la presente investigación, se apoya en la norma ISO 37301.

En este trabajo fueron identificados los instrumentos dentro de los procesos utilizados para la planeación de la ejecución de proyectos de las organizaciones sin fines de lucro, ENL: el Alcance, Tiempo y Costos, así como su impacto en el desempeño de los proyectos y su mejora a través del modelo propuesto, que rescata las mejores prácticas del mundo de las mismas entidades, al mismo tiempo fueron identificadas cuales fueron las prácticas del mundo empresarial que pueden ser adaptadas en mayor o menor grado. Para la gestión de la implementación se encontraron 18 instrumentos en su mayoría propuestos y rescatados del mundo empresarial entre ellos; 10 de ellos fueron adaptados para las ENL sin problemas en un 100%; 4 de ellos para el 36% de las ENL; mientras que de los instrumentos propios del mundo empresarial sólo un 28% pudieron ser adaptados para la ENL. En general, se pudo identificar a partir de los resultados que la ENLs no cuentan con una estructura funcional que facilite la formulación y ejecución de proyectos, ya que las decisiones se toman en altos niveles empresariales, lo que a veces unido a la falta de experiencia dificulta la aplicación del uso de las herramientas, y retrasa la consecución y captación de recursos a través de los proyectos. Finalmente, el modelo representa una propuesta inicial que puede ser analizada, modificada y está sujeto a la mejora continua.

Las pequeñas y medianas empresas (PyME) de desarrollo de software, generan la mayor fuerza laboral en el eje troncal de Bolivia. Sus características principales son que cuentan con recursos humanos y de capital reducido, no tienen un estándar de desarrollo implementado, por subsistir toman cualquier trabajo que se le presenta notándose la falta de especialización en un nicho determinado y haciendo que las estimaciones en tiempo y recursos sean irreales. Los estándares existentes de desarrollo de software no se enmarcan en esta realidad de las PyME, haciendo que su implementación sea nula. Hay modelos específicos para las PyME como la ISO/IEC 29110, IT-MARK, Modelo de Procesos para la Industria de Software (MoProSoft), Mejora de Proceso de Software Brasilero (MPS.BR) y Competisoft que tratan de estandarizar las PyME. Estos modelos tienen en común que la gestión del conocimiento es esencial en las PyME por el conocimiento tácito que se encuentra interiorizado en los miembros del grupo de desarrollo de software. La gestión del conocimiento es crucial en las PyME de desarrollo de software debido a su naturaleza extensiva de generación y consumo de conocimiento. Por otro lado, las redes de conocimiento son otro mecanismo importante donde los individuos pueden interactuar en temas específicos de un área determinada del conocimiento. Estas redes de conocimiento son importantes en el desarrollo de software, ya que es el mecanismo por el cual se puede transmitir el conocimiento tácito y el conocimiento explícito entre personas. En la actualidad no se han encontrado trabajos que relacionen la gestión del conocimiento y las redes de conocimiento como mecanismo de soporte para las PyME de desarrollo de software. Es por estos motivos que en este trabajo de investigación se propone un modelo de gestión del conocimiento para las PyME de desarrollo de software del eje troncal de Bolivia.

The emerging application of electroporation requires high voltage pulses having a pulse-width in the nanosecond range. The essential use of a capacitor results in an increase in the size of the electroporator circuit. This paper discusses the modification of a conventional Marx generator circuit to achieve the high voltage electroporation pulses with a minimal chip size of the circuit. The reduced capacitors are attributed to a reduction in the number of stages used to achieve the required voltage boost. The paper proposes the improved isolation between two capacitors with the usage of optocouplers. Parametric analysis is presented to define the tuneable range of the electroporator circuit.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés The world population is on the rise, which demands higher food production. The reduction in the amount of land under cultivation due to urbanization makes this more challenging. The solution to this problem lies in the artificial cultivation of crops. IoT and sensors play an important role in optimizing the artificial cultivation of crops. The selection of sensors is important in order to ensure a better quality and yield in an automated artificial environment. There are many challenges involved in selecting sensors due to the highly competitive market. This paper provides a novel approach to sensor selection for saffron cultivation in an IoT-based environment. The crop used in this study is saffron due to the reason that much less research has been conducted on its hydroponic cultivation using sensors and its huge economic impact. A detailed hardware-based framework, the growth cycle of the crop, along with all the sensors, and the block layout used for saffron cultivation in a hydroponic medium are provided. The important parameters for a hydroponic medium, such as the concentration of nutrients and flow rate required, are discussed in detail. This paper is the first of its kind to explain the sensor configurations, performance metrics, and sensor-based saffron cultivation model. The paper discusses different metrics related to the selection, use and role of sensors in different IoT-based saffron cultivation practices. A smart hydroponic setup for saffron cultivation is proposed. The results of the model are evaluated using the AquaCrop simulator. The simulator is used to evaluate the value of performance metrics such as the yield, harvest index, water productivity, and biomass. The values obtained provide better results as compared to natural cultivation.

In Wireless Sensor Networks (WSNs), routing algorithms can provide energy efficiency. However, due to unbalanced energy consumption for all nodes, the network lifetime is still prone to degradation. Hence, energy efficient routing was developed in this article by selecting cluster heads (CH) with the help of adaptive whale optimization (AWOA) which was used to reduce time-consumption delays. The multi-objective function was developed for CH selection. The clusters were then created using the distance function. After establishing groupings, the supercluster head (SCH) was selected using the benefit of a fuzzy inference system (FIS) which was used to collect data for all CHs and send them to the base station (BS). Finally, for the data-transfer procedure, hop count routing was used. An Oppositional-based Whale optimization algorithm (OWOA) was developed for multi-constrained QoS routing with the help of AWOA. The performance of the proposed OWOA methodology was analyzed according to the following metrics: delay, delivery ratio, energy, NLT, and throughput and compared with conventional techniques such as particle swarm optimization, genetic algorithm, and Whale optimization algorithm

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Mobility and low energy consumption are considered the main requirements for wireless body area sensor networks (WBASN) used in healthcare monitoring systems (HMS). In HMS, battery-powered sensor nodes with limited energy are used to obtain vital statistics about the body. Hence, energy-efficient schemes are desired to maintain long-term and steady connectivity of the sensor nodes. A sheer amount of energy is consumed in activities such as idle listening, excessive transmission and reception of control messages, packet collisions and retransmission of packets, and poor path selection, that may lead to more energy consumption. A combination of adaptive scheduling with an energy-efficient protocol can help select an appropriate path at a suitable time to minimize the control overhead, energy consumption, packet collision, and excessive idle listening. This paper proposes a region-based energy-efficient multipath routing (REMR) approach that divides the entire sensor network into clusters with preferably multiple candidates to represent each cluster. The cluster representatives (CRs) route packets through various clusters. For routing, the energy requirement of each route is considered, and the path with minimum energy requirements is selected. Similarly, end-to-end delay, higher throughput, and packet-delivery ratio are considered for packet routing. Akbar, Shuja and Mehdi, Muhammad Mohsin and Jamal, M.

La ciencia y tecnología (CyT) buscan el bienestar social y optimizar el estado de vida de la población. A nivel mundial, hay un consenso en la relación positiva que guardan el gasto en investigación y desarrollo (I+D) y el impulso a la innovación, así como la relación positiva entre la innovación y el crecimiento económico. Algunas economías han fracasado en el impulso a la CyT y esto ha generado un retraso económico y una divergencia frene a las economías más desarrolladas. Este comportamiento de rezago ha provocado que diverjan las economías y que se encuentren dos grupos de países, unos líderes y otros seguidores en el avance del nuevo conocimiento. Ecuador es un país en el que se han realizado esfuerzos importantes en materia de CyT, sin embargo, aún está muy lejos de colocarse como un referente en Iberoamérica. Para ubicar este país en el concierto internacional en materia de la eficiencia en CyT, se realiza una evaluación de tipo no-paramétrica que permite obtener un índice que se construye a través de una frontera de eficiencia de una muestra de estudio de 29 países iberoamericanos. El objetivo de esta investigación es evaluar el desempeño eficiente de la Ciencia y Tecnología en el Ecuador para el periodo de estudio que comprende los años 1990-2017. La metodología es mixta, de tipo no experimental y empírica, diacrónica, bajo un nivel explicativa, longitudinal no-paramétrica al estilo benchmarking, por medio de la técnica Análisis Envolvente de Datos o DEA (Data Envelopment Analysis) que permite crear índices de eficiencia de forma comparativa para valorar el trabajo de los sistemas de innovación desde los indicadores más eficientes a los menos eficientes. El modelo CCR arroja resultados que permiten tener elementos para ofrecer alternativas de mejora en el desempeño de Ecuador en materia de CyT.

Ibero-american International University > Research > Articles and Books Abierto Inglés This is an effort to analyze the reaction of stock prices of Indian public and private banks listed in NSE and BSE to the announcement of seven best case news events. Several recent studies have analyzed the correlation between stock prices and news announcements; however, there is no evidence on how private and public sector Indian bank stocks react to important news events independently. We examine these features by concentrating on a sample of banking and government news events. We classify these news events to create a group of negative and a group of positive tone of announcements (sentiments). The statistical results show that the negative banking news announcements had a one-month impact on private banks, with statistically significant negative mean CARs. However, with highly statistically substantial negative mean CARs, the influence of the negative banking news announcements on public banks was observed for two months after the news was published. Furthermore, the influence of the positive banking news on private banks persisted a month after the news was published. Positive banking news events had an influence on public banks for five days after they were published. The study concludes that public bank stocks react more to negative news announcements than positive news announcements in the same manner as the sentimental polarity of the news announcements as compared to private bank stocks. First, we retrieved the news articles published in prominent online financial news portals between 2017 and 2020, and the seven major news events were extracted and classified using multi-class text classification. The Random Forest classifier produced a significant accuracy of 94% with pre-trained embeddings of DistilBERT, a neural network model, which outperformed the traditional feature representation technique, TF-IDF. The training data for the classifier were balanced using the SMOTE sampling technique Dogra, Varun and Alharithi, Fahd S. and Álvarez, Roberto Marcelo and Singh, Aman and Qahtani, Abdulrahman M.

Ibero-american International University > Research > Articles and Books Abierto Inglés This is an effort to analyze the reaction of stock prices of Indian public and private banks listed in NSE and BSE to the announcement of seven best case news events. Several recent studies have analyzed the correlation between stock prices and news announcements; however, there is no evidence on how private and public sector Indian bank stocks react to important news events independently. We examine these features by concentrating on a sample of banking and government news events. We classify these news events to create a group of negative and a group of positive tone of announcements (sentiments). The statistical results show that the negative banking news announcements had a one-month impact on private banks, with statistically significant negative mean CARs. However, with highly statistically substantial negative mean CARs, the influence of the negative banking news announcements on public banks was observed for two months after the news was published. Furthermore, the influence of the positive banking news on private banks persisted a month after the news was published. Positive banking news events had an influence on public banks for five days after they were published. The study concludes that public bank stocks react more to negative news announcements than positive news announcements in the same manner as the sentimental polarity of the news announcements as compared to private bank stocks.

Ibero-american International University > Research > Articles and Books Abierto Inglés The standard optimization of open-pit mine design and production scheduling, which is impacted by a variety of factors, is an essential part of mining activities. The metal uncertainty, which is connected to supply uncertainty, is a crucial component in optimization. To address uncertainties regarding the economic value of mining blocks and the general problem of mine design optimization, a minimum-cut network flow algorithm is employed to give the optimal ultimate pit limits and pushback designs under uncertainty. A structure that is computationally effective and can manage the joint presentation and treatment of the economic values of mining blocks under various circumstances is created by the push re-label minimum-cut technique. In this study, the algorithm is put to the test using a copper deposit and shows similarities to other stochastic optimizers for mine planning that have already been created. Higher possibilities of reaching predicted production targets are created by the algorithm’s earlier selection of more certain blocks with blocks of high value. Results show that, in comparison to a conventional approach using the same algorithm, the cumulative metal output is larger when the uncertainty in the metal content is taken into consideration. There is also an additional 10% gain in net present value.

The current coronavirus (COVID-19) pandemic is a rare/special situation where people can express their feelings on Internet-based social networks. Social media is emerging as the biggest platform in recent years where people spend most of their time expressing themselves and their emotions. This research is based on gathering data from Twitter and analyzing the behavior of the people during the COVID-19 lockdown. The research is based on the logic expressed by people in this perspective and emotions for the suffering of COVID-19 and lockdown. In this research, we have used a Long Short-Term Memory (LSTM) network model with Convolutional Neural Network using Keras python deep-learning library to determine whether social media platform users are depressed in terms of positive, negative, or neutral emotional out bust based on their Twitter posts. The results showed that the model has 88.14% accuracy (representation of the correct prediction over the test dataset) after 10 epochs which most tweets showed had neutral polarity.

Dynamic and heterogeneous fog networks are difficult to manage and a considerable amount of overhead could be realized while managing ever increasing load on foglets. Fog computing plays a vital role in managing ever increasing processing demands from diverse IoT-based applications. Smart healthcare systems work with the assistance of sensor-based devices and automatic data collection and processing can speed up overall system functionality. In the proposed work, a novel framework for smart health care is presented where a series of activities are performed with prime objective of reducing latency and execution time.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Traditional optimization of open pit mine design is a crucial component of mining endeavors and is influenced by many variables. The critical factor in optimization is the geological uncertainty, which relates to the ore grade. To deal with uncertainties related to the block economic values of mining blocks and the general problem of mine design optimization, under unknown conditions, the best ultimate pit limits and pushback designs are produced by a minimum cut algorithm. The push–relabel minimal cut algorithm provides a framework for computationally efficient representation and processing of the economic values of mining blocks under multiple scenarios. A sequential Gaussian simulation-based smoothing spline technique was created. To produce pushbacks, an efficient parameterized minimum cut algorithm is suggested. An analysis of Indian iron ore mining was performed. The developed mine scheduling algorithm was compared with the conventional algorithm, and the results show that when uncertainty is considered, the cumulative metal production is higher and there is an additional increase of about 5% in net present value. The results of this work help the mining industry to plan mines in such a way that can generate maximum profit from the deposits.

Ibero-american International University > Research > Articles and Books Abierto Inglés This study involves a working limestone mine that supplies limestone to the cement factory. The two main goals of this paper are to (a) determine how long an operating mine can continue to provide the cement plant with the quality and quantity of materials it needs, and (b) explore the viability of combining some limestone from a nearby mine with the study mine limestone to meet the cement plant’s quality and quantity goals. These objectives are accomplished by figuring out the maximum net profit for the ultimate pit limit and production sequencing of the mining blocks. The issues were resolved using a branch-and-cut based sequential integer and mixed integer programming problem. The study mine can exclusively feed the cement plant for up to 15 years, according to the data. However, it was also noted that the addition of the limestone from the neighboring mine substantially increased the mine’s life (85 years). The findings also showed that, when compared with the production planning formulation that the company is now using, the proposed approach creates 10% more profit. The suggested method also aids in determining the desired desirable quality of the limestone that will be transported from the nearby mine throughout each production stage.

O mundo real tem se integrado velozmente ao mundo virtual. A cada novo avanço tecnológico são ultrapassadas barreiras que tornam a separação desses dois mundos cada vez mais difícil de ser percebida nitidamente. Esta turbidez causada na percepção de quanto os recursos digitais estão incorporados nas atividades e ações do cotidiano humano e das empresas, se deve em muito à naturalidade com que essas tecnologias são assimiladas. Então, o que justifica a não adoção massiva dessas tecnologias nos meios de produção, mais especificamente no setor industrial? Trouxemos esse questionamento para um domínio de análise espacial aproximada da realidade local na qual estamos inseridos. Desta forma, fizemos um levantamento que nos permitisse compreender quais são os elementos geradores de dificuldades para o desenvolvimento de uma mudança do setor industrial do Rio Grande do Norte em direção à Indústria 4.0. Para tanto, observamos a existência de empresas industriais onde este processo de mudança já foi iniciado, bem como traçamos perspectivas para que o mesmo ocorra nos mais diversificados ecossistemas de produção industrial do estado. Como resultado, traçamos um diagnóstico do cenário da transição local que nos permitiu identificar fatores proeminentes geradores de instabilidade e intensificadores da complexidade nesse processo de mudança tecnológica. Esta pesquisa em nível de Mestrado está inserida na Linha de Especialização: Prevenção, Qualidade e Engenharia, Orientação: Pesquisa e Desenvolvimento (P+D) do Mestrado em Engenharia Industrial - UNINI-MX e para alcançar os objetivos traçados calcou-se em um estudo de natureza qualitativa, delineada por uma abordagem descritiva.

El trabajo fue enmarcado bajo la metodología de enfoque profesionalizador en la subcategoría de investigación-acción, debido a que se está describiendo una propuesta de mejora en un contexto real. El proyecto se divide en dos secciones, la primera se enfoca en toda la revisión bibliográfica en bases científicas necesarias para el desarrollo de la propuesta, destacando el análisis de las actividades principales de una empresa de control de plagas, como sus riesgos y sus técnicas más utilizadas, así como también en el desarrollo de planes de emergencia tradicionales concentrados en situaciones donde ocurran accidentes a pequeña o gran escala. La segunda parte consiste en la metodología del proyecto, donde fueron llevadas a cabo diversas actividades de campo para cumplir con todos los objetivos propuestos en el diseño del plan de emergencias. Con este fin fueron utilizadas diversas técnicas de recolección de datos como entrevistas a profundidad, evaluaciones de conocimiento y desempeño, evaluaciones de proveedores y revisión de equipos y materiales con checklists, para luego pasar al análisis y la sistematización de toda la información obtenida, lo que dio como resultado la redacción de procedimientos de emergencia, los cuales conforman el cuerpo de la propuesta final. Como resultado de toda la metodología presentada, se obtuvo una propuesta de plan de emergencias ante crisis sanitarias, la cual deberá ser valorada por la Alta Dirección de la empresa para su respectivo análisis de viabilidad y decidir si esta será implementada o si deberá ser revisada para una nueva presentación en un futuro.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español En el Ecuador se emplea mucho el carbón activado para uso industrial en tratamiento de agua y aire, sin embargo, no existe una producción. La falta de producto local genera una alta demanda por carbón extranjero, sobre todo desde China y Estados Unidos; esto produce un precio alto pero que el mercado está dispuesto a pagar. Este estudio tiene como finalidad desarrollar un diseño de planta de carbón activado en la ciudad de Milagro – Ecuador, a partir de un subproducto de la industria azucarera (bagazo) que permita obtener un producto de la misma o mejor calidad que el mercado nacional está acostumbrado. De igual forma, generar una fuente de empleó para los profesionales ecuatorianos y ofrecer un producto a un menor costo que el carbón importado desde otros países. Para ello, se realizará primero un pequeño estudio de mercado por medio de una encuesta a empresas encargadas de importar o emplear carbón activado, esto con el fin de determinar las necesidades y requerimientos que el mercado tiene. Basado en la información recopilada se desarrollará un prototipo para validar que cumpla con las especificaciones de calidad, para finalmente realizar un escalamiento hacia una producción a nivel a industrial realizando diagrama de flujo, layout de la planta y un balance económico que estime el tiempo de retorno de la inversión y su monto aproximado. Los resultados obtenidos en la encuesta permitieron estimar el consumo de carbón activado a nivel nacional, principales países de importación, costo de producto por kilogramo, principales características físico químicas, entre otros. En el proceso de prototipado se obtuvo una muestra de carbón activado a partir de bagazo con un contenido de humedad y ceniza muy bueno, adicionalmente, se logró realizar el escalamiento hacia el proceso industrial por medio de un diagrama de flujo. Finalmente, el balance económico mostró que el producto presenta una buena rentabilidad al poder generar un producto de buena calidad y a menor costo de lo que mercado actual está empleando. De manera que, se concluye que el presente estudio logro realizar el diseño primario de una planta de carbón actividad en Ecuador. Paredes Martinez, Jose Jacobo jojapare@espol.edu.ec

It may be a virus, bacterial, or fungal, depending on the contagious pathogen that damages the lung’s tiny air sacs (alveoli). Patients with underlying disorders such as asthma, a weakened immune system, hospitalized babies, and older persons on ventilators are all at risk, particularly if pneumonia is not detected early. Despite the existing approaches for its diagnosis, low accuracy and efficiency require further research for more accurate systems. This study is a similar endeavor for the detection of pneumonia by the use of X-ray images. The dataset is preprocessed to make it suitable for transfer learning tasks. Different pre-trained convolutional neural network (CNN) variants are utilized, including VGG16, Inception-v3, and ResNet50. Ensembles are made by incorporating CNN with Inception-V3, VGG-16, and ResNet50. Besides the common evaluation metrics, the performance of the pre-trained and ensemble deep learning models is measured with Cohen’s kappa as well as the area under the curve (AUC). Experimental results show that Inception-V3 with CNN attained the highest accuracy and recall score of 99.29% and 99.73%, respectively Mujahid, Muhammad and Rustam, Furqan and Álvarez, Roberto Marcelo and Vidal Mazón, Juan Luis and Díez, Isabel de la Torre and Ashraf, Imran UNSPECIFIED, UNSPECIFIED, roberto.alvarez@uneatlantico.es, juanluis.vidal@uneatlantico.es, UNSPECIFIED, UNSPECIFIED

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés β-Thalassemia is one of the dangerous causes of the high mortality rate in the Mediterranean countries. Substantial resources are required to save a β-Thalassemia carriers’ life and early detection of thalassemia patients can help appropriate treatment to increase the carrier’s life expectancy. Being a genetic disease, it can not be prevented however the analysis of several indicators in parents’ blood can be used to detect disorders causing Thalassemia. Laboratory tests for Thalassemia are time-consuming and expensive like high-performance liquid chromatography, Complete Blood Count (CBC) with peripheral smear, genetic test, etc. Red blood indices from CBC can be used with machine learning models for the same task. Despite the available approaches for Thalassemia carriers from CBC data, gaps exist between the desired and achieved accuracy. Moreover, the data imbalance problem is studied well which makes the models less generalizable. This study proposes a highly accurate approach for β-Thalassemia detection using red blood indices from CBC augmented by supervised machine learning. In view of the fact that all the features do not carry predictive information regarding the target variable, this study employs a unified framework of two features selection techniques including Principal Component Analysis (PCA) and Singular Vector Decomposition (SVD). The data imbalance between β-Thalassemia carrier and non-carriers is handled by Synthetic Minority Oversampling Technique (SMOTE) and Adaptive Synthetic (ADASYN). Extensive experiments are performed using many state-of-the-art machine learning models and deep learning models. Experimental results indicate the superiority of the proposed approach over existing approaches with an accuracy score of 0.96.

A segurança do trabalho é uma área de estudo de muita importância, visto que toda a economia mundial depende das atividades laborais e, com isso, torna-se importante proteger as pessoas envolvidas nesse processo. É um consenso comum de que se deve preservar a vida dos trabalhadores, entretanto há uma objeção no que diz respeito aos custos que essa proteção pode gerar. Em um mercado competitivo, onde as empresas precisam reduzir custos, não se pode considerar de forma utópica de que devemos proteger os trabalhadores a qualquer custo, pois assim a empresa não consegue controlar suas finanças e, consequentemente, não consegue se posicionar de forma competitiva no mercado. Na construção civil não é diferente. Por se tratar de uma das áreas da economia que mais emprega pessoas e uma das que apresenta maiores riscos à vida dos trabalhadores, acaba sendo também uma das áreas que tem maior índice de acidentes. Nesse cenário, a segurança do trabalho se encarrega de atuar para minimizar todos esses riscos e danos, sendo necessário que se realize estudos como este que se encarregue de maximizar a segurança oferecida aos trabalhadores com o menor custo possível, apresentando-se como uma boa alternativa para ambos os lados. Esta pesquisa se trata de um estudo de casos, descritivo, quantitativo e aplicado, dividida em duas etapas distintas. A primeira se trata de uma revisão da bibliografia existente, onde encontra-se subsídios de assuntos relacionados a segurança do trabalho, bem-estar do trabalhador, sistemas de proteções coletivas, responsabilidade do empregador e sustentabilidade na prevenção e construção. A etapa seguinte tem como objetivo analisar situações de riscos em construção de edificações e classificar as proteções mais comum de forma a obter o melhor custo/benefício. O intuito é verificar se há sistemas mais eficientes que outros, considerando investimentos similares, sendo possível priorizar essas alternativas, permitindo ao gestor da empresa adotar as melhores medidas, de forma sustentável e economicamente viável. O estudo permitiu concluir que os sistemas de ancoragem provisória e definitiva são os que apresentam melhores retornos pelo recurso investido e, consequentemente, são aqueles que devem ser priorizados.

La accidentabilidad derivada de las actividades que requieren la intervención manual de los trabajadores, las condiciones de las instalaciones y la falta de una atención apropiada por parte de la Gerencia de operaciones de Metalúrgica Met-Mex Peñoles S.A. de C.V., Unidad Bermejillo requieren una atención desde una perspectiva diferente. Aunado a los esfuerzos de reducir la accidentabilidad por medio de metodologías o herramientas, tales como STOP (Seguridad en el Trabajo mediante la Observación Preventiva), Disciplina Operativa, Reglas de seguridad de cero tolerancia, entre otras, es necesario verificar desde la fuente posible de generación de los accidentes. No basta con buscar la conducta de los trabajadores, no basta con buscar medidas disciplinarias al no cumplir los procedimientos y reglas operativas. La fatiga generada por los movimientos repetitivos, sobreesfuerzos y posturas incómodas propician la pérdida de control y precisión de los movimientos al realizar as actividades. Aunado a esta pérdida de control, los equipos inadecuados, las herramientas y el peso de estas pueden desencadenar en golpes, heridas, pérdida del equilibrio, contacto con temperaturas extremas, bordes, filos, etc. La ergonomía en el ámbito laboral industrial es la propuesta de análisis para la determinación de las condiciones de la estación de trabajo, las posturas incómodas y los sobreesfuerzos y establecer un programa de ergonomía para prevenir accidentes, lesiones y enfermedades profesionales. Iniciar mediante un diagnóstico, desarrollar los estudios, determinar el nivel de riesgo ergonómico mediante la evaluación de extremidades superiores y la realización de propuestas de mejora de la estación de trabajo ayudó a establecer condiciones laborales aceptables de tal manera que el riesgo ergonómico se situó en niveles aceptables.

Ibero-american International University > Teaching > Master's Final Projects Cerrado Español Según la Teoría Tricondicional del Comportamiento Seguro para que un trabajador realice un comportamiento seguro se tienen que cumplir tres condiciones “Saber hacer”, “Poder hacer” y “Quere hacer”, en este contexto, los requisitos para los sistemas de gestión de Seguridad y Salud de las empresas mineras del Perú que se encuentran especificados en la normativa legal aplicable son en su mayoría tendientes al cumplimiento de las condiciones “Saber hacer” y “Poder hacer” en consecuencia los sistemas de gestión de Seguridad y Salud tradicionales tienen como foco de aplicación principal las condiciones y “Saber hacer” y “Poder hacer” no considerando acciones para el cumplimiento de la condición “Querer hacer”, esta situación representa un obstáculo para lograr la reducción o eliminación de los accidentes e incidentes laborales en cualquier Unidad Minera del Perú. El Objetivo General del presente trabajo es desarrollar una propuesta que sirva como referencia para la implementación de un programa de Seguridad Basada en el Comportamiento que complemente los requisitos legales establecidos por las normas aplicables. La metodología aplicada para el presente trabajo es cualitativa, el diseño de la investigación es del tipo exploratorio de corte transversal, la población está constituida por 4078 reportes realizados entre los años 2010 y 2020 en la Unidad Minera del estudio, la muestra es no probabilística del tipo por conveniencia donde se contemplan 1563 reportes registrados entre los años 2015 a 2020. En el presente trabajo se determinó que los requisitos legales aplicables a los sistemas de gestión de Seguridad y Salud y los procesos del Sistema de Gestión de Seguridad y Salud implementado en la Unidad Minera se centran principalmente relacionados a las condiciones “Poder hacer” y “Saber hacer”, que el 89 % de los eventos analizados estuvieron relacionados con el comportamiento de los trabajadores, que existen comportamientos alternativos que pueden evitar la ocurrencia de eventos no deseados si estos son reforzados inmediatamente y positivamente usando el material adecuado. Como conclusiones del presente trabajo se evidencia que los requisitos establecidos por las normas aplicables y que fueron implementados por la Unidad Minera están alineados a los componentes de los sistemas de gestión Seguridad y Salud tradicionales los que tienen como foco principal el cumplimiento de las condiciones “Poder hacer” y “Saber hacer ” de la Teoría Tricondicional del Comportamiento Seguro, la implementación de un Programa Seguridad Basada en el Comportamiento (SBC) de acuerdo al análisis realizado es la alternativa para superar la brecha existente y cumplir con la condición “Quere hacer” lo que potencialmente puede derivar en una reducción significativa del número de accidentes e incidentes debido a que el 89 % de los eventos analizados pudieron ser evitados por un comportamiento alternativo lógico y que estuvo al alcancen de los trabajadores involucrados en los eventos, el proceso de implementación del Programa de Seguridad Basada en el Comportamiento (SBC) descrito puede servir como una guía para aquellas unidades mineras del Perú que identifiquen sus brechas relacionadas a la condición “Querer hacer”. Las palabras claves del presente trabajo son Seguridad Basada en el Comportamiento (SBC), Comportamiento Seguro, Comportamiento Alternativo Relevante, Teoría Tricondicional del Comportamiento Seguro, legislación peruana aplicable.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español Los diferentes hospitales públicos y privados requieren del uso de maquinarias y equipos biomédicos para atender a la población atendida con problemas de salud, por lo que es necesario que dichos equipos funcionen correctamente y se encuentren en óptimas condiciones de funcionamiento cuando sean requeridos. La empresa CORP–GTB Cía. Ltda. es una empresa de servicios consolidada en el mercado dedicada al mantenimiento preventivo y correctivo de equipos biomédicos en establecimientos de salud públicos y privados; no obstante, el departamento técnico de la misma presenta falencias en la gestión de los procesos operativos. El estudio tuvo como objetivo identificar las causas de la ineficiencia existente en las operaciones llevadas a cabo por parte del personal del departamento técnico y su relación con la falta de agilismo presentada dentro del área. El estudio es de enfoque mixto, donde se aplicaron métodos cuantitativos como la encuesta y cualitativos como la entrevista y la discusión de grupos. Se determinó que los niveles de satisfacción laboral y clima laboral no son óptimos; asimismo, en encontró que la falta de estructuración de los procesos operativos propicia la improvisación, generando atascos en las actividades y retrasos en las entregas. Mediante el análisis de los procesos y el enfoque del agilismo se logró realizar una propuesta de gestión del departamento técnico, con el objeto de mejorar los tiempos de entrega, mejorar la satisfacción y clima laboral, e impulsar el crecimiento de la empresa. Se concluye que la metodología basada en el agilismo permite el desarrollo de actividades a través de la optimización del uso de los recursos, mejorando la interacción dentro de los procesos, con lo cual se responde efectivamente al cliente y maximizando el valor.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español El comercio de productos médicos incrementó con el contexto de la pandemia permitiendo realizar emprendimientos, uno de ellos es la compra, venta y distribución de insumos médicos. La empresa donde se enfoca el estudio ha tenido un rápido crecimiento y no cuenta con procesos estandarizados, registros y un control eficiente de la cantidad de productos que se compra en función a la demanda que existe. La organización cuenta con clientes reconocidos y desea mejorar el tiempo de respuesta hacía el consumidor final. Para cumplir con el objetivo se analizó los datos históricos de las actividades de compra, venta y distribución identificando los puntos que ayudan y obstaculizan el buen funcionar de la compañía para establecer un método de pronóstico de la demanda que se ajuste de mejor forma a la realidad. Para cumplir con los propósitos deseados, se realizó un análisis FODA con los colaboradores de la compañía señalando las fortalezas y debilidades, como también, las oportunidades y amenazas, esto permitió obtener información para realizar estrategias que ayuden a tomar acciones en aquellos puntos que se consideran frágiles y los que se pueden aprovechar, se realizó un análisis de las actividades operativas como lo son compra, venta y distribución, para identificar actividades que puedan mejorar el desempeño de las áreas y se levantó información para realizar un flujograma de procesos, permitiendo observar donde introducir oportunidades de mejoras para que el proceso se vuelva eficiente mediante un listado de actividades, estableciendo responsables para llevar de forma correcta cada función. Con el Análisis FODA se determinó las estrategias y responsables de realizarlas, se establecieron procesos para lograr orden y estandarización en cada área analizada y se pudo establecer un método de pronóstico de la demanda basado en datos históricos para saber la cantidad de insumos necesaria para satisfacer la demanda.

El trabajo realizado presentó como principal aporte una propuesta para la evaluación del grado de interactividad en los objetos virtuales de aprendizaje (OVA), lo cual permitió un acercamiento a la estandarización en el diseño y será un aporte sobre cómo deberán ser diseñados si se espera de ellos algún grado de interactividad, estableciendo siete aspectos necesarios en el diseño, los cuales fueron usados como referencias para proponer una forma práctica en la valoración y categorización de estos. También, se hizo un aporte para comprender la interactividad de los OVA, puesto que esta se confunde con el impacto visual; en esta propuesta se relacionaron temáticas de avanzada en el diseño, tales como los estímulos supernormales. Así mismo, se propusieron unos modos de estudio que se incluyeron en el diseño del OVA, generando así, por parte del autor, un aporte en las caracterizaciones, reconocimientos y diferenciaciones, en función de los niveles de interactividad, siendo de utilidad a las entidades educativas en la modalidad virtual. Por último, el resultado más importante fue proporcionar claridad acerca de cómo puede ser evaluada la interactividad en los OVA.

El presente trabajo tiene como objetivo dar respuesta a las necesidades que se detecten en la Universidad Popular Autónoma de Veracruz, a través del análisis de los resultados obtenidos con el instrumento aplicado, buscando que la Universidad preste un servicio de calidad en las gestiones administrativas que se realicen. Esta problemática se presenta debido a que en la Institución no existe un área encargada de velar por la calidad de los servicios, así como por la satisfacción de sus colaboradores.Con el análisis de datos obtenidos se plantea la propuesta de creación de un área / departamento que se encargue de todo lo relativo a la calidad en la Universidad, dando la continuidad requerida para alcanzar un programa de mejora continua, así como las funciones específicas y perfiles para dicho departamento. Todo esto tomando como base los lineamientos de Sistemas de Gestión de Calidad como lo establece la norma ISO 9000.

Moreover, it is widely utilizing for preventing injuries of athletes during a practice session and in few cases, it leads to muscle fatigue. At present, emerging technology like the internet of things (IoT) and sensors is empowering to monitor and visualize the physical data from any remote location through internet connectivity. In this study, an IoT-enabled wearable device is proposing for monitoring and identifying the muscle fatigue condition using a surface electromyogram (sEMG) sensor. Normally, the EMG signal is utilized to display muscle activity. Arduino controller, Wi-Fi module, and EMG sensor are utilized in developing the wearable device. The Time-frequency domain spectrum technique is employed for classifying the three muscle fatigue conditions including mean RMS, mean frequency, etc. A real-time experiment is realized on six different individuals with developed wearable devices and the average RMS value assists to determine the average threshold of recorded data. The threshold level is analyzed by calculating the mean RMS value and concluded three fatigue conditions as >2 V: Extensive); 1–2 V: Moderate, and <1 V: relaxed. The warning alarm system was designed in LabVIEW with three color LEDs to indicate the different states of muscle fatigue. Moreover, the device is interfaced with the cloud through the internet provided with a Wi-Fi module embedded in wearable devices. The data available in the cloud server can be utilized for forecasting the frequency of an individual to muscle fatigue.

Las plantas para obtención de los biocombustibles emplean durante su proceso de obtención cantidades importantes de agua en los distintos procesos derivando en un consumo de un elemento esencial para el desarrollo humano y que luego de su empleo producen cantidades de efluentes con alta carga orgánica que nos dificulta su disposición en los drenajes y espejos de agua tanto superficiales como subterráneos.Tal es el caso del producto derivado de la columna de destilación, la cuan surge como material derivado las vinazas, producto este que es de una coloración amarronado oscuro con alta carga orgánica y aspecto muy negativo.Estas vinazas por su alta concentración de nutrientes, las plantas actuales de producción de biocombustibles lo derivan a un sistema de separación centrifugo y evaporación obteniendo un producto secundario denominado burlanda húmeda que es un producto que se deriva a alimentos de animales.También, en tecnologías más avanzadas, parte de este producto se derivan a una planta de secado, la cual, se le extrae el resto de agua y se almacena en silos con un mayor valor agregado, para obtención de la burlanda seca y se materias primas para obtención de alimento balanceado para animales.Todo hace pensar que el tema de las vinazas está solucionado, sin embargo, aún se tiene un camino más para recorrer, ya que la cantidad de agua derivada del proceso de centrifugado, de evaporación y de secado conserva alta carga orgánica y valores de acides entre 3 y 4.Esta agua por los valores detallados aun no puede ser empleado en los cauces de drenaje superficial, subterráneos y cloacal. Aquí entramos en el otro paso de recuperación, ya que aprovechando la alta carga orgánica que ostenta, se puede realizar, a través de un sistema anaeróbico, la producción de biogás, lo cual, el desagüe remanente, al emplear la materia orgánica presente, se obtiene un drenaje de agua amigable con el medio receptor.La producción de biogás obtenido y dada la cantidad producida, se puede emplear a través de un mote-generador energía eléctrica la cua puede emplearse para servicios de la misma planta con un ahorro importante de energía o bien a través de un transformador elevador, suministrar y vender energía eléctrica a la distribución energética en media o alta tensión del suministro central, obteniendo una cierta rentabilidad y mejorar desde el punto de vista ambiental el consumo de energía no renovable.En este contexto aún nos queda por analizar otro capítulo importante en el aprovechamiento energético y es a través de los gases de combustión del motor.Estos gases tienen una temperatura elevada (400°C) y caudal de salida importante y se podría analizar su recuperación. Este proceso estaría centrada en interceptar una caldera de recuperación los cuales se puede generar vapor de baja que ceda calor a un intercambiador de calor y generar agua caliente para servicios, (consumo, sanitario, calefacción) que además redundara en disminuir la temperatura de salida de gases al exterior.

A medida que estas redes y aplicaciones van evolucionando, crecen las posibilidades de vulnerabilidad con riesgos de ataques, esto se traduce en daños y pérdida para las distintas entidades que la utilizan. En tal sentido, se requiere de protección idónea para resguardar los sistemas de información y para ello, el Honeypots es un recurso de red ficticia que además de detectar al intruso, semejando el sistema de gestión, captura el comportamiento de esos intrusos, permitiendo al usuario evaluar controles posteriores como medida preventiva. La presente investigación tiene como objetivo Monitorear el rendimiento del Sistema Honeypots en la detección y clasificación de intrusos en ciber-ataques que permita generar políticas de seguridad. La metodología implementada es Tecnológica, consta de cinco (5) fases para proyectos tecnológicos planteados por Arias (2016) que son: Diagnóstico, Diseño, Recursos, Monitoreo y Evaluación. El monitoreo a través del Honeypots se realiza mediante grabación del comportamiento del intruso, y emite un informe detallado al respecto. Los resultados de estas pruebas demostraron que una red Honeypot tiene un grado de eficiencia mayor o igual que el de un antivirus convencional.Giovanni Carlos Lorusso M.

El estudio tiene como contexto geográfico la cuenca endorreica de Tajzara, ubicada en la zona altoandina del Departamento de Tarija (Bolivia). Aborda el análisis y aplicación de técnicas de Restauración Ecohidrológica para mejorar los procesos hidrológicos en el ecosistema natural de Lagunas de Tajzara, o Sitio Ramsar 1030, planteando la alteración del ecosistema natural de la cuenca como problemática, por sobrepastoreo y uso inadecuado del suelo como causas que favorecen este desequilibrio ambiental. En busca de contribuir a la solución de la problemática de los flujos hídricos que sustentan la recarga de los humedales en la cuenca de Tajzara, se plantea como objetivo general: analizar y evaluar los ecosistemas de recarga hídrica para formular alternativas de restauración ecohidrológica, que contribuyan a restablecer el equilibrio de los flujos hídricos que alimentan la recarga en los humedales de la cuenca. La metodología consiste en la descripción de la cuenca, determinación de longitud del transecto, delimitación de unidades, identificación de zonas de recarga hídrica potencial, cuantificación de la recarga hídrica mensual y anual, determinación del grado de conservación de las zonas de recarga hídrica, diseño de obras no estructurales para el incremento de los flujos hídricos del suelo y para incrementar la capacidad de almacenamiento de agua en el suelo. El área estudiada alcanza 45.161,11 ha, con seis unidades con recarga moderada y seis con recarga alta, en un total de 878,58 mm/año; el estado de conservación de las zonas de recarga se determinó en 3,8 veces excedida la carga animal. Finalmente, se han diseñado obras no estructurales, zanjas de infiltración, bordos en contorno o media lunas para restablecer el equilibrio de los flujos hídricos en los humedales de la cuenca.

Subjects > Nutrition Ibero-american International University > Research > Doctoral Thesis Cerrado Español La producción e industrialización de frutas autóctonas ̶ como la toronja, papaya y mango ̶ ha cobrado mayor importancia económica en los últimos años. Las tecnologías alimentarias desarrolladas para tales frutas habitualmente generan residuos orgánicos (cáscaras, semillas y bagazo), que constituyen un costo de disposición final. El aprovechamiento integral de las materias primas y sus subproductos es premisa fundamental para el incremento de la rentabilidad de toda industria de la transformación. Dada la naturaleza bioquímica de los residuos del procesamiento de frutas, fue la intención del presente proyecto el diseño de un protocolo de obtención de productos de alto valor agregado como la pectina y flavonoides antioxidantes. La investigación fue realizada desde agosto 2020 a noviembre 2021 en la planta de procesamiento de alimentos y el Laboratorio de Inocuidad de Alimentos y Análisis Industrial (LIAAI) de la Universidad ISA (República Dominicana), a partir de las cáscaras de lechosa (Carica papaya) variedad Tainung 1 o Red Lady, toronja (Citrus paradisi Macf) y mango (Mangifera indica) Banilejo o Mameyito. Se evaluaron diferentes variables en el proceso de extracción tales como: materia prima (cáscara), tiempo de molienda (tamaño de partícula), proporción cáscara deshidratada: agua acidulada, pH, tiempo y temperatura de extracción. Se estudiaron parámetros de rendimiento, calidad fisicoquímica, costo y funcionalidad tecnológica de los productos. Como resultado, se diseñó un protocolo de extracción de pectinas y flavonoides de residuos de frutas autóctonas como alternativa para reducir las importaciones, pudiendo con ello: conocer los parámetros de proceso óptimos para la obtención de extractos pécticos de las cáscaras bajo estudio; cuantificar los flavonoides presentes y su capacidad antioxidante; medir las características fisicoquímicas y rendimiento de las pectinas; comparar la funcionalidad tecnológica de la mejor con una pectina comercial y conocer la relación Beneficio/Costo del proceso; finalmente, se publicó un artículo científico en una revista indexada.

In the same way, deep learning techniques are also used to develop software and techniques that pose a danger to privacy, democracy, and national security. Fake content in the form of images and videos using digital manipulation with artificial intelligence (AI) approaches has become widespread during the past few years. Deepfakes, in the form of audio, images, and videos, have become a major concern during the past few years. Complemented by artificial intelligence, deepfakes swap the face of one person with the other and generate hyper-realistic videos. Accompanying the speed of social media, deepfakes can immediately reach millions of people and can be very dangerous to make fake news, hoaxes, and fraud. Besides the well-known movie stars, politicians have been victims of deepfakes in the past, especially US presidents Barak Obama and Donald Trump, however, the public at large can be the target of deepfakes. To overcome the challenge of deepfake identification and mitigate its impact, large efforts have been carried out to devise novel methods to detect face manipulation. This study also discusses how to counter the threats from deepfake technology and alleviate its impact. The outcomes recommend that despite a serious threat to society, business, and political institutions, they can be combated through appropriate policies, regulation, individual actions, training, and education. In addition, the evolution of technology is desired for deepfake identification, content authentication, and deepfake prevention. Different studies have performed deepfake detection using machine learning and deep learning techniques such as support vector machine, random forest, multilayer perceptron, k-nearest neighbors, convolutional neural networks with and without long short-term memory, and other similar models. This study aims to highlight the recent research in deepfake images and video detection, such as deepfake creation, various detection algorithms on self-made datasets, and existing benchmark datasets.

Deepfakes, in the form of audio, images, and videos, have become a major concern during the past few years. Complemented by artificial intelligence, deepfakes swap the face of one person with the other and generate hyper-realistic videos. Accompanying the speed of social media, deepfakes can immediately reach millions of people and can be very dangerous to make fake news, hoaxes, and fraud. Besides the well-known movie stars, politicians have been victims of deepfakes in the past, especially US presidents Barak Obama and Donald Trump, however, the public at large can be the target of deepfakes. To overcome the challenge of deepfake identification and mitigate its impact, large efforts have been carried out to devise novel methods to detect face manipulation. This study also discusses how to counter the threats from deepfake technology and alleviate its impact. The outcomes recommend that despite a serious threat to society, business, and political institutions, they can be combated through appropriate policies, regulation, individual actions, training, and education. In addition, the evolution of technology is desired for deepfake identification, content authentication, and deepfake prevention. Different studies have performed deepfake detection using machine learning and deep learning techniques such as support vector machine, random forest, multilayer perceptron, k-nearest neighbors, convolutional neural networks with and without long short-term memory, and other similar models. This study aims to highlight the recent research in deepfake images and video detection, such as deepfake creation, various detection algorithms on self-made datasets, and existing benchmark datasets.

Infrastructure-less networks make it desirable for many researchers to publish and bind multimedia services. Each node in this infrastructure-less network acts as self-organizing and re-configurable. It allows services to deploy and attain from another node over the ad hoc network. The service composition aims to provide a user’s requirement by combining different atomic services based on non-functional QoS parameters such as reliability, availability, scalability, etc. To provide service composition in MANET is challenging because of the node mobility, link failure, and topology changes, so a traditional protocol will be sufficient to obtain real-time services from mobile nodes. In this paper, the ad hoc on-demand distance vector protocol (AODV) is used and analyzed based on MANET’s QoS (Quality of Service) metrics. The QoS metrics for MANET depends on delay, bandwidth, memory capacity, network load, and packet drop. The requester node and provider node broker acts as a composer for this MANET network. The authors propose a QoS-based Dynamic Secured Broker Selection architecture (QoSDSBS) for service composition in MANET, which uses a dynamic broker and provides a secure path selection based on QoS metrics. The proposed algorithm is simulated using Network Simulator (NS2) with 53 intermediate nodes and 35 mobile nodes of area 1000 m × 1000 m. The comparative results show that the proposed architecture outperforms, with standards, the AODV protocol and affords higher scalability and a reduced network load Ramalingam, Rajakumar and Muniyan, Rajeswari and Dumka, Ankur and Singh, Devesh Pratap and Mohamed, Heba G. and Singh, Rajesh and Anand, Divya and Delgado Noya, Irene UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, UNSPECIFIED, divya.anand@uneatlantico.es, irene.delgado@uneatlantico.es

There is a huge limitation in the sensing layer as the IoT devices here have low computational power, limited storage and less battery life. So, this huge amount of data needs to be stored on the cloud. The information and the data sensed by these devices is made accessible on the internet from where medical staff, doctors, relatives and family members can access this information. This helps in improving the treatment as well as getting faster medical assistance, tracking of routine activities and health focus of elderly people on frequent basis.

The proper verification of users plays a vital role during communication over a social network to protect the personal data of users. Multifarious protocols have been implemented to secure the confidential data of the users, but these protocols have various limitations and are incapable of providing secrecy of data against various attacks, such as replay and cryptanalysis attacks. In this article, the authors proposed a novel method for security verification of the social network model using an improved three-party authenticated key exchange (3PAKE) protocol based on symmetric encryption and (ECC) elliptic curve cryptography. The outcome of the paper demonstrates that our proposed algorithm provides the desired secrecy to the confidential data exchange over social networks in real-time and consumes less time in comparison to existing protocols. Our protocol consumes a search time of 0.09 s, overall communication steps took 2 during the verification, and depth plies was 3 along with 20 visited nodes. The 3PAKE protocol has been considered a suitable approach for social network secrecy during information exchange between user and server, thereby providing greater secrecy to the user in data exchange over social networks and more robustness against multifarious known attacks, such as cryptanalysis and replay attacks in real-time

Ibero-american International University > Research > Articles and books Abierto Inglés One of the toughest biometrics and document forensics problems is confirming a signature’s authenticity and legal identity. A forgery may vary from a genuine signature by specific distortions. Therefore, it is necessary to continuously monitor crucial distinctions between real and forged signatures for secure work and economic growth, but this is particularly difficult in writer-independent tasks. We thus propose an innovative and sustainable writer-independent approach based on a Siamese neural network for offline signature verification. The Siamese network is a twin-like structure with shared weights and parameters. Similar and dissimilar images are exposed to this network, and the Euclidean distances between them are calculated. The distance is reduced for identical signatures, and the distance is increased for different signatures. Three datasets, namely GPDS, BHsig260 Hindi, and BHsig260 Bengali datasets, were tested in this work. The proposed model was analyzed by comparing the results of different parameters such as optimizers, batch size, and the number of epochs on all three datasets. The proposed Siamese neural network outperforms the GPDS synthetic dataset in the English language, with an accuracy of 92%.

Ibero-american International University > Teaching > Final Master Projects Cerrado Español La escasez de agua resulta una problemática mundial cada vez más persistente y que afecta la vida de las personas. Las instituciones educativas del sector privado no están exentas de las consecuencias que esto provoca, como el encarecimiento del vital líquido por parte de los sistemas gubernamentales encargados de proveerlo. Lamentablemente la urbanización y el uso de materiales impermeables, junto al cambio climático, han agravado el problema; evitando que los pozos, de donde se extrae la mayoría del agua para consumo humano, puedan reabastecerse al nivel de la demanda requerida. En zonas con una considerable precipitación anual, los Sistemas de Captación de Agua de Lluvia (SCALL), han resultado ser un método eficiente para solventar y reducir los gastos de consumo de agua potable. Utilizando el método racional americano se estima el cálculo del Potencial de Captación de agua de Lluvia (POTCALL), mientras que el cálculo de la demanda se obtiene tomando en cuenta el número de alumnos consumo por persona obtenido de las normas técnicas complementaria (NTC) y la duración del temporal de lluvias. Su diseño es amplio pues debe adaptarse a las necesidades de las personas o instituciones a las que va dirigida. El grado de potabilización dependerá del uso al que se destine el agua, pero su inversión llega a recuperarse a corto plazo y los ahorros generados se muestran rápidamente. La propuesta de diseño para la universidad donde planteo el proyecto da como resultado un ahorro, desde el primer año, de un 11% respecto al gasto que provoca el consumo de agua que suministra el Sistema Intermunicipal de Agua Potable y Alcantarillado (SIAPA), logrando subir hasta un 16% a partir del segundo año.

Antecedentes. La medicina nuclear es una de las herramientas más efectivas tanto para el diagnóstico como para el tratamiento en pacientes con cáncer; sin embargo, los radionucleidos utilizados pueden alcanzar los sistemas de alcantarillado por medio de diversos canales y contaminar las aguas residuales. Debido a que la cifra de estos pacientes es abrumadoramente creciente y que la descarga hospitalaria es entre 4 y 12 veces más alta que la doméstica, este problema ha sido motivo de preocupación a nivel mundial. Desafortunadamente, en Guatemala no existe un planteamiento para gestionar estas descargas en la que se plasmen las medidas correctivas que contribuyan a la protección de las fuentes hídricas. En este trabajo, se propone un sistema de gestión que defina los protocolos a seguir desde el diagnóstico de un paciente hasta su último tratamiento de esta enfermedad que garantice el aislamiento de cualquier sustancia nuclear contaminante. Método. Se llevó a cabo la revisión de literatura para realizar análisis (mono dato, promedio, rango o valor mínimo) de características de parámetros agrupados de aguas residuales de hospitales que hacen uso de medicina nuclear, así como la normativa y legislación vigente. Otro aspecto identificado son los protocolos y medidas sanitarias de control que utilizan o no estos centros de salud; en el marco de la normativa nacional vigente relacionada. Resultados. De acuerdo con los resultados obtenidos, se propone un sistema de gestión que incluye los recursos humanos, medidas no estructurales de manejo interno, actualización en el AG 236-2006 (parámetros, límites permisibles, glosario) y tratamiento con procesos de sedimentación/precipitación, ultrafiltración y desintegración radiactiva que han sido simulados teóricamente para reducir el porcentaje de actividad radiactiva. Conclusiones. Este sistema (PTAR+R) puede contribuir a disminuir la actividad reactiva, logrando un menor impacto medioambiental y, sobre todo, reducir el riesgo a la salud por contacto con dichas aguas.

Ibero-american International University > Research > Articles and Books Cerrado Inglés Smart vehicle parking is a collaborative effort of technology and human innovation where the efforts are to be minimized to save time and efforts. In smart cities it is one of the common challenges to introduce smart parking to increase parking efficiency and combat numerous issues like identification of free parking slot and real-time dynamic updation on traffic to save fuel and energy. In this work, a new cloud-based smart parking architecture is proposed that can help in predicting the available free parking slots in smart cities. Initially, the methodology collects the car count at any near by parking using Internet of Things (IoT) and Cloud-based approach. Later, the approach uses the Kernel Least Mean Square algorithm to make heuristic predictions about future vacancy using auto-regression. The proposed approach thus utilizes the online learning or model training. To validate the efficacy of the proposed work, the testing is done on the real-time dataset. The extensive numerical investigation is performed on parking lots of four international airports of a smart city in actual deployment scenarios. The experimentation has revealed superior performance of the method in terms of vacancy prediction.

The proposed approach thus utilizes the online learning or model training. To validate the efficacy of the proposed work, the testing is done on the real-time dataset. The extensive numerical investigation is performed on parking lots of four international airports of a smart city in actual deployment scenarios. The experimentation has revealed superior performance of the method in terms of vacancy prediction.

Emerging smart technologies and various cloud services offered could be utilized and integrated into the power industry to enhance the overall process, especially in the fault monitoring and normalizing fields in distribution systems. This paper introduces smart fault monitoring and normalizing technologies in distribution systems by using one of the most popular cloud service platforms, the Microsoft Azure Internet of Things (IoT) Hub, together with some of the related services. A hardware prototype was constructed based on part of a real underground distribution system network, and the fault monitoring and normalizing techniques were integrated to form a system.

Guayaquil, Ecuador, is in a tropical area on the equatorial Pacific Ocean coast of South America. Since 2008 the city has been increasing its population, vehicle fleet and manufacturing industries. Within the city there are various industrial and urban land uses sharing the same space. With regard to air quality there is a lack of government information on it. Therefore, the research’s aim was to investigate the spatio-temporal characteristics of PM1 and PM2.5 concentrations and their main influencing factors. For this, both PM fractions were sampled and a bivariate analysis (cross-correlation and Pearson's correlation), multivariate linear and logistic regression analysis was applied. Hourly and daily PM1 and PM2.5 were the dependent variables, and meteorological variables, occurrence of events and characteristics of land use were the independent variables. We found 48% exceedances of the PM2.5-24 h World Health Organization 2021 threshold’s, which questions the city’s air quality. The cross-correlation function and Pearson’s correlation analysis indicate that hourly and daily temperature, relative humidity, and wind speed have a complex nonlinear relationship with PM concentrations. Multivariate linear and logistic regression models for PM1-24 h showed that rain and the flat orography of cement plant sector decrease concentrations; while unusual PM emission events (traffic jams and vegetation-fires) increase them. The same models for PM2.5-24 h show that the dry season and the industrial sector (strong activity) increase the concentration of PM2.5-24 h, and the cement plant decrease them. Public policies and interventions should aim to regulate land uses while continuously monitoring emission sources, both regular and unusual.

Ibero-american International University > Research > Articles and Books Abierto Inglés Rivers play a major role within ecosystems and society, including for domestic, industrial, and agricultural uses, and in power generation. Forecasting of suspended sediment yield (SSY) is critical for design, management, planning, and disaster prevention in river basin systems. It is difficult to forecast the SSY using conventional methods because these approaches cannot handle complicated non-stationarity and non-linearity. Artificial intelligence techniques have gained popularity in water resources due to handling complex problems of SSY. In this study, a fully automated generalized single hybrid intelligent artificial neural network (ANN)-based genetic algorithm (GA) forecasting model was developed using water discharge, temperature, rainfall, SSY, rock type, relief, and catchment area data of eleven gauging stations for forecasting the SSY. It is applied at individual gauging stations for SSY forecasting in the Mahanadi River which is one of India’s largest peninsular rivers. All parameters of the ANN are optimized automatically and simultaneously using the GA. The multi-objective algorithm was applied to optimize the two conflicting objective functions (error variance and bias). The mean square error objective function was considered for the single-objective optimization model. Single and multi-objective GA-based ANN, autoregressive and multivariate autoregressive models were compared to each other. It was found that the single-objective GA-based ANN model provided the best accuracy among all comparative models, and it is the most suitable substitute for forecasting SSY. If the measurement of SSY is unavailable, then single-objective GA-based ANN modeling approaches can be recommended for forecasting SSY due to comparatively superior performance and simplicity of implementation Yadav, Arvind and Chithaluru, Premkumar and Singh, Aman and Albahar, Marwan Ali and Jurcut, Anca and Álvarez, Roberto Marcelo and Mojjada, Ramesh Kumar and Joshi, Devendra UNSPECIFIED, UNSPECIFIED, aman.singh@uneatlantico.es, UNSPECIFIED, UNSPECIFIED, roberto.alvarez@uneatlantico.es, UNSPECIFIED, UNSPECIFIED

Hence, we aimed to design a systematic review and meta-analysis for their effectiveness in alleviating premenstrual symptoms. The published randomized controlled trials (RCTs) were extracted from Google scholar, PubMed, Scopus and PROSPERO databases. The risk of bias in randomized trials was assessed by Cochrane risk-of-bias tool. The main outcome parameters were analysed separately based on the Premenstrual Symptom Screening Tool and PMTS and DRSP scores. Secondary parameters of somatic, psychological, and behavioural subscale symptoms of PSST were also analysed. Data synthesis was performed assuming a random-effects model, and standardized mean difference (SMDs) was analysed using SPSS version 28.0.0 (IBM, Armonk, NY, USA). A total of 754 articles were screened, and 15 RCTs were included (n = 1211 patients). Primary results for participants randomized to an intervention reported reduced PSST (n = 9), PMTS (n = 2), and DSR (n = 4) scores with (SMD = −1.44; 95% CI: −1.72 to −1.17), (SMD = −1.69; 95% CI: −3.80 to 0.42) and (SMD = 2.86; 95% CI: 1.02 to 4.69) verses comparator with substantial heterogeneity. Physical (SMD = −1.61; 95% CI = −2.56 to −0.66), behavioural (SMD = −0.60; 95% CI = −1.55 to0.35) and mood (SMD = 0.57; 95% CI = −0.96 to 2.11) subscale symptom groupings of PSST displayed similar findings. Fifty-three studies (n = 8) were considered at low risk of bias with high quality. Mild adverse events were reported by four RCTs.

Ibero-american International University > Research > Articles and books Abierto Inglés The probability of medical staff to get affected from COVID19 is much higher due to their working environment which is more exposed to infectious diseases. So, as a preventive measure the body temperature monitoring of medical staff at regular intervals is highly recommended. Infrared temperature sensing guns have proved its effectiveness and therefore such devices are used to monitor the body temperature. These devices are either used on hands or forehead. As a result, there are many issues in monitoring the temperature of frontline healthcare professionals. Firstly, these healthcare professionals keep wearing PPE (Personal Protective Equipment) kits during working hours and as a result it would be very difficult to monitor their body temperature. Secondly, these healthcare professionals also wear face shields and in such cases monitoring temperature by exposing forehead needs removal of face shield. Doing so after regular intervals is surely uncomfortable for healthcare professionals. To avoid such issues, this paper is disclosing a technologically advanced face shield equipped with sensors capable of monitoring body temperature instantly without the hassle of removing the face shield. This face shield is integrated with a built-in infrared temperature sensor. A total of 10 such face shields were printed and assembled within the university lab and then handed over to a group of ten members including faculty and students of nursing and health science department. This sequence was repeated four times and as a result 40 healthcare workers participated in the study. Thereafter, feedback analysis was conducted on questionnaire data and found a significant overall mean score of 4.59 out of 5 which indicates that the product is effective and worthy in every facet.

Environmental, social, and governance (ESG) metrics are used to evaluate the sustainability level of an organization. According to the statistics, 53% of respondents in the BlackRock survey are concerned about the availability of low ESG data, which is critical for determining the organization’s sustainability level. This obstacle can be overcome by implementing Industry 4.0 technologies, which enable real-time data, data authentication, prediction, transparency, authentication, and structured data. Based on the review of previous studies, it was determined that only a few studies discussed the implementation of Industry 4.0 technologies for ESG data and evaluation. The objective of the study is to discuss the significance of ESG data and report, which is used for the evaluation of the sustainability of an organization. In this regard, the assimilation of Industry 4.0 technologies (Internet of Things (IoT), artificial intelligence (AI), blockchain, and big data for obtaining ESG data by an organization is detailed presented to study the progress of advancement of these technologies for ESG. On the basis of analysis, this study concludes that consumers are concerned about the ESG data, as most organizations develop inaccurate ESG data and suggest that these digital technologies have a crucial role in framing an accurate ESG report. After analysis a few vital conclusions are drawn such as ESG investment has benefited from AI capabilities, which previously relied on self-disclosed, annualized company information that was susceptible to inherent data issues and biases.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Technology’s expansion has contributed to the rise in popularity of social media platforms. Twitter is one of the leading social media platforms that people use to share their opinions. Such opinions, sometimes, may contain threatening text, deliberately or non-deliberately, which can be disturbing for other users. Consequently, the detection of threatening content on social media is an important task. Contrary to high-resource languages like English, Dutch, and others that have several such approaches, the low-resource Urdu language does not have such a luxury. Therefore, this study presents an intelligent threatening language detection for the Urdu language. A stacking model is proposed that uses an extra tree (ET) classifier and Bayes theorem-based Bernoulli Naive Bayes (BNB) as the based learners while logistic regression (LR) is employed as the meta learner. A performance analysis is carried out by deploying a support vector classifier, ET, LR, BNB, fully connected network, convolutional neural network, long short-term memory, and gated recurrent unit. Experimental results indicate that the stacked model performs better than both machine learning and deep learning models. With 74.01% accuracy, 70.84% precision, 75.65% recall, and 73.99% F1 score, the model outperforms the existing benchmark study.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Thyroid disease prediction has emerged as an important task recently. Despite existing approaches for its diagnosis, often the target is binary classification, the used datasets are small-sized and results are not validated either. Predominantly, existing approaches focus on model optimization and the feature engineering part is less investigated. To overcome these limitations, this study presents an approach that investigates feature engineering for machine learning and deep learning models. Forward feature selection, backward feature elimination, bidirectional feature elimination, and machine learning-based feature selection using extra tree classifiers are adopted. The proposed approach can predict Hashimoto’s thyroiditis (primary hypothyroid), binding protein (increased binding protein), autoimmune thyroiditis (compensated hypothyroid), and non-thyroidal syndrome (NTIS) (concurrent non-thyroidal illness). Extensive experiments show that the extra tree classifier-based selected feature yields the best results with 0.99 accuracy and an F1 score when used with the random forest classifier. Results suggest that the machine learning models are a better choice for thyroid disease detection regarding the provided accuracy and the computational complexity. K-fold cross-validation and performance comparison with existing studies corroborate the superior performance of the proposed approach.

The proposed approach can predict Hashimoto’s thyroiditis (primary hypothyroid), binding protein (increased binding protein), autoimmune thyroiditis (compensated hypothyroid), and non-thyroidal syndrome (NTIS) (concurrent non-thyroidal illness). Extensive experiments show that the extra tree classifier-based selected feature yields the best results with 0.99 accuracy and an F1 score when used with the random forest classifier. Results suggest that the machine learning models are a better choice for thyroid disease detection regarding the provided accuracy and the computational complexity. K-fold cross-validation and performance comparison with existing studies corroborate the superior performance of the proposed approach.

However, software development teams are unaware of SDP and do not have easy access to relevant models and techniques. The major reason for this problem seems to be the fragmentation of SDP research and SDP practice. To unify SDP research and practice this article introduces a cloud-based, global, unified AI framework for SDP called DePaaS—Defects Prediction as a Service. The article describes the usage context, use cases and detailed architecture of DePaaS and presents the first response of the industry practitioners to DePaaS. In a first of its kind survey, the article captures practitioner’s belief into SDP and ability of DePaaS to solve some of the known challenges of the field of software defect prediction. This article also provides a novel process for SDP, detailed description of the structure and behaviour of DePaaS architecture components, six best SDP models offered by DePaaS, a description of algorithms that recommend SDP models, feature sets and tunable parameters, and a rich set of challenges to build, use and sustain DePaaS.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Device-to-device (D2D) communication has attracted many researchers, cellular operators, and equipment makers as mobile traffic and bandwidth demands have increased. It supports direct communication within devices with no need for any intermediate node and, therefore, offers advantage in 5G network while providing wide cell coverage range and frequency reuse. However, establishing acceptable and secure mechanism for D2D communication which ensures confidentiality, integrity, and availability is an issue encountered in this situation. Furthermore, in a resource-constrained IoT environment, these security challenges are more critical and difficult to mitigate, especially during emergence of IoT with 5G network application scenarios. To address these issues, this paper proposed a security mechanism in 5G network for D2D wireless communication dependent on lightweight modified elliptic curve cryptography (LMECC). The proposed scheme follows a proactive routing protocol to discover services, managing link setup, and for data transfer with the aim to reduce communication overhead during user authentication. The proposed approach has been compared against Diffie–Hellman (DH) and ElGamal (ELG) schemes to evaluate the protocol overhead and security enhancement at network edge. Results proved the outstanding performance of the proposed LMECC for strengthening data secrecy with approximate 13% and 22.5% lower overhead than DH and ELG schemes.

Leaf disease impacts the quality and productivity of paddy crops. Therefore, tackling this issue as early as possible is mandatory to reduce its impact. Consequently, in recent years, deep learning methods have been essential in identifying and classifying leaf disease. Deep learning is used to observe patterns in disease in crop leaves. For instance, organizing a crop’s leaf according to its shape, size, and color is significant. To facilitate farmers, this study proposed a Convolutional Neural Networks-based Deep Learning (CNN-based DL) architecture, including transfer learning (TL) for agricultural research. In this study, different TL architectures, viz. InceptionV3, VGG16, ResNet, SqueezeNet, and VGG19, were considered to carry out disease detection in paddy plants. The approach started with preprocessing the leaf image; afterward, semantic segmentation was used to extract a region of interest. Consequently, TL architectures were tuned with segmented images. Finally, the extra, fully connected layers of the Deep Neural Network (DNN) are used to classify and identify leaf disease. The proposed model was concerned with the biotic diseases of paddy leaves due to fungi and bacteria. The proposed model showed an accuracy rate of 96.4%, better than state-of-the-art models with different variants of TL architectures. After analysis of the outcomes, the study concluded that the anticipated model outperforms other existing models Gautam, Vinay and Trivedi, Naresh K. and Singh, Aman and Mohamed, Heba G. and Delgado Noya, Irene and Kaur, Preet and Goyal, Nitin UNSPECIFIED, UNSPECIFIED, aman.singh@uneatlantico.es, UNSPECIFIED, irene.delgado@uneatlantico.es, UNSPECIFIED, UNSPECIFIED

Ibero-american International University > Research > Articles and Books Cerrado Inglés The development of underwater wireless sensor networks (UWSNs) has attracted great interest from many researchers and scientists to detect and monitor unfamiliar underwater domains. To achieve this goal, collecting data with an underwater network of sensors is primordial. Moreover, real-time information transmission needs to be achieved through efficient and enabling technologies for node deployment and data collection in UWSN. The Internet of Things (IoT) helps in real time data transmission, and it has great potential in UWSN, i.e., the Internet of Underwater Things (IoUT). The Internet of Underwater Things (IoUT) is a modern communication ecosystem for undersea things in marine and underwater environments. Intelligent boats and ships, automatic maritime transportation, location and navigation, undersea discovery, catastrophe forecasting and avoidance, as well as intelligent monitoring and security are all intertwined with IoUT technology. In this paper, the enabling technologies of UWSN along with several fundamental key aspects are scrupulously explained. The study aims to inquire about node deployment and data collection strategies, and then encourages researchers to lay the groundwork for new node deployment and advanced data collection techniques that enable effective underwater communication techniques. Besides different types of communication media, applications of UWSNs are also part of this paper. Various existing data collection protocols based on the deployment models are simulated using Network Simulator (NS 2.30) to analyse and compare the performance of state-of-the-art techniques.

This paper reports the behaviour of solid urban waste generation in the Metropolitan Area of Misiones, during a period of seven days. The waste analysed came from collection routes by household sampling points determined according to the land use and socioeconomic level of the population in the study area. The methodology consisted of visualising the sample universe, selecting the household waste collection routes and then classifying and analysing their composition according to ASTM D5231-92 (2016). This strategy was considered valid, given that the habits and customs of the population are closely related to the socioeconomic levels that directly affect consumption and consequently the quality of waste. Organic matter (51.80%) was the most representative, followed by materials with recycling potential, such as plastic (13.90%), glass (7.90%), paper and cardboard (7.80%), metals/aluminium (2.20%) and tetrabrik (2.60%). The quality of MSW was not uniform between cities, with Garupá (61.50%) being the city that generated the most organic waste, followed by Posadas (57.50%) and ending with Candelaria (29.00%) with a marked decrease. As a limitation of the method, it was determined that the results are representative of each city and of the winter season.

Unfired admixed soil blocks are made up of soil plus stabilizers such as binders, fibers, or a combination of both. Soil is abundant on Earth, and it has been used to provide shelter to millions of people. The manufacturing and usage of cement and cement blocks raise several environmental and economic challenges. Due to disposal issues, agricultural and industrial waste is currently the biggest hazard to the environment and humanity in the world. Consequently, environmental degradation brought on by agricultural waste harms the ecology. As a result, researchers are attempting to develop an alternative to cement blocks, and various tests on unfired admixed soil blocks have been done. This investigation uses agricultural waste (i.e., paddy straw fiber and sugarcane bagasse ash) and industrial waste (i.e., marble dust) in manufacturing unfired admixed soil blocks. Under this investigation, the applicability of unfired soil blocks admixed with marble dust, paddy straw fiber, and bagasse ash was studied. The marble dust level ranged from 25% to 35%, bagasse ash content ranged from 7.5% to 12.5%, and the content of paddy straw fiber ranged from 0.8% to 1.2% by soil dry weight. Various tests were conducted on the 81 mix designs of the prepared unfired admixed soil blocks to find out the physical properties of the block followed by modeling and optimization. The findings demonstrate that the suggested method is a superior alternative to burned bricks for improving the physical properties of admixed soil blocks without firing

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés At this time, efforts are being made on a worldwide scale to accomplish sustainable development objectives. It has, thus, now become essential to investigate the part of technology in the accomplishment of these Sustainable Development Goals (SDGs), as this will enable us to circumvent any potential conflicts that may arise. The importance of wastewater management in the accomplishment of these goals has been highlighted in the study. The research focuses on the role of fourth industrial revolution in meeting the Sustainable Goals for 2030. Given that water is the most important resource on the planet and since 11 of the 17 Sustainable Goals are directly related to having access to clean water, effective water management is the most fundamental need for achieving these goals. The age of Industry 4.0 has ushered in a variety of new solutions in many industrial sectors, including manufacturing, water, energy, healthcare, and electronics. This paper examines the present creative solutions in water treatment from an Industry-4.0 viewpoint, focusing on big data, the Internet of Things, artificial intelligence, and several other technologies. The study has correlated the various concepts of Industry 4.0 along with water and wastewater management and also discusses the prior work carried out in this field with help of different technologies.

It has, thus, now become essential to investigate the part of technology in the accomplishment of these Sustainable Development Goals (SDGs), as this will enable us to circumvent any potential conflicts that may arise. The importance of wastewater management in the accomplishment of these goals has been highlighted in the study. The research focuses on the role of fourth industrial revolution in meeting the Sustainable Goals for 2030. Given that water is the most important resource on the planet and since 11 of the 17 Sustainable Goals are directly related to having access to clean water, effective water management is the most fundamental need for achieving these goals. The age of Industry 4.0 has ushered in a variety of new solutions in many industrial sectors, including manufacturing, water, energy, healthcare, and electronics.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés White blood cell (WBC) type classification is a task of significant importance for diagnosis using microscopic images of WBC, which develop immunity to fight against infections and foreign substances. WBCs consist of different types, and abnormalities in a type of WBC may potentially represent a disease such as leukemia. Existing studies are limited by low accuracy and overrated performance, often caused by model overfit due to an imbalanced dataset. Additionally, many studies consider a lower number of WBC types, and the accuracy is exaggerated. This study presents a hybrid feature set of selective features and synthetic minority oversampling technique-based resampling to mitigate the influence of the above-mentioned problems. Furthermore, machine learning models are adopted for being less computationally complex, requiring less data for training, and providing robust results. Experiments are performed using both machine- and deep learning models for performance comparison using the original dataset, augmented dataset, and oversampled dataset to analyze the performances of the models. The results suggest that a hybrid feature set of both texture and RGB features from microscopic images, selected using Chi2, produces a high accuracy of 0.97 with random forest. Performance appraisal using k-fold cross-validation and comparison with existing state-of-the-art studies shows that the proposed approach outperforms existing studies regarding the obtained accuracy and computational complexity.

Ibero-american International University > Research > Articles and books Abierto Inglés The most important and emerging characteristic of Wireless Body Area Networks (WBANs), which differentiates them from other wired and wireless area networks, is mobility. Therefore, the routing protocols for WBAN are designed in such a way that they can deal with dynamic changes in topology and provide maximum throughput, packet delivery ratio, average end-to-end delay, and minimum energy consumption. Thus, achieving optimal values for every performance parameter becomes a big challenge. This work investigates the performance of three separate path discovery protocols, such as Destination-Sequenced Distance-Vector Routing (DSDV), Ad Hoc On-demand Distance Vector (AODV), and Ad Hoc On-demand Multipath Distance Vector Routing protocol (AOMDV), for two different mobility models with a fixed-positioned sink. During experimentation, the AOMDV routing protocol achieves a high packet delivery ratio (PDR), average end-to-end delay, and throughput as compared to other routing protocols.

Introducción: Las Enfermedades de Transmisión Alimentaria (conocidas comúnmente con el acrónimo de ETAs), impactan significativamente en los sistemas de salud de los países. Objetivo: Realizar una búsqueda temática que identifica los principales peligros de tipo biológico causantes de ETAs descritos en Costa Rica, y relacionar los principales alimentos de origen animal con los cuales se vinculan. Metodología: Realizamos una búsqueda de información científica bajo la modalidad de revisión literaria de cohorte narrativo y descriptivo, desde junio de 2015 hasta diciembre de 2020. Seleccionamos para la presente revisión bibliográfica, únicamente artículos con descripción de uno o varios organismos patógenos que estuvieran vinculados con matrices alimentarias de origen animal, en el territorio costarricense. Resultados: Identificamos 27 tipos de organismos biológicos asociados con cuadros de ETAs, aislados de distintas matrices de origen animal en Costa Rica. Conclusión: Existe una pluralidad de organismos frecuentemente asociados con infecciones, toxoinfecciones e infestaciones en el ser humano. Con un panorama creciente de incremento en el consumo de productos de origen animal para hacer frente al crecimiento poblacional al año 2050, estos retos se incrementan en paralelo. Para ello es imperativo la implementación del concepto Una Salud en los esquemas productivos de los países.

Universidad Internacional do Cuanza > Research > Articles and books Abierto Inglés Background: To address the current pandemic, multiple studies have focused on the development of new mHealth applications to help curb the number of infections, these applications aim to accelerate the identification and self-isolation of people exposed to SARS-CoV- 2, the coronavirus known to cause COVID-19, by being in close contact with infected individuals. Objective: The main objectives of this paper are: 1)To analyze the current status of COVID-19 apps available the main virtual stores: Google Play Store and App Store, and 2)To propose a novel mobile application based on the limitations of the analyzed apps. Methods: The search for apps in this research was carried out in the main virtual stores: Google Play Store and App Store, until May 2021. After the analysis of the selected apps, a novel app is proposed whose main function will be the multiple transmission of information about the patient's symptoms from the application, without the need for phone calls or chat in real time. For its development, the flowchart shown in this session is followed. Results: The search yielded a total of 50 apps, of which 24 were relevant to this study. It is important to note that 23 of the apps analyzed are free. Of the total number of apps, 54% are available for Android and iOS operating systems. 50% of the apps have more than 5 thousand downloads. This means that Covid-19 related apps are in high demand among mobile device users today. The developed app is called COVINFO and its name comes from the union of the words COVID-19 and information, inserted in such a way that the user can get an idea of the app's functionality just by listening or reading the resulting name. The application has been created for mobile devices with Android operating system, being compatible with Android 4.4 and higher. Conclusions: Of the apps found, 37.5% only offer information about the virus and the necessary measures to avoid infection. During the analysis it was detected that 12.5% of the apps are focused on locating outbreaks and that none of them have been successful for the following reasons: not being interconnected to share data; and the request for access to the user's geolocation, generating distrust on the part of the user who, consequently, rejects them. This work addresses the development of an application for the transmission of the user's symptoms to his regular doctor, based on the fact that only 16.6% of the existing applications have this functionality. The COVINFO app offers a service that no other application on the market has: doctor-patient interaction without the need for calls or chat in real time for constant monitoring by the doctor of the patient's condition and evolution.

The integration was justified by the scarce explicit references to sustainability and CSR found in traditional project management guidelines, norms, and standards. The new framework was used to structure a Sustainability Management Plan, which made it possible to incorporate sustainability criteria throughout the life cycle of the training project. The training proposal in Project Design, Management, and Evaluation was chosen, among several alternatives, by a multi-criteria selection process (fuzzy AHP) in the context of project scope management. The results reveal a great heterogeneity among the models and the lack of a base of key indicators in sustainability and CSR measurement tools as well as of explicit references to sustainability in project management standards.

In such a situation implementation of a vaccination can be viewed as essential but its success will be dependent on availability and transparency in the distribution process that will be shared among the stakeholders. Various distributed ledgers (DLTs) such as blockchain provide an open, public, immutable system that has numerous applications due the mentioned abilities. In this paper the authors have proposed a solution based on blockchain to increase the security and transparency in the tracing of COVID-19 vaccination vials. Smart contracts have been developed to monitor the supply, distribution of vaccination vials. The proposed solution will help to generate a tamper-proof and secure environment for the distribution of COVID-19 vaccination vials. Proof of delivery is used as a consensus mechanism for the proposed solution. A feedback feature is also implemented in order to track the vials lot in case of any side effect cause to the patient.

En esta Tesis Doctoral se desarrolla un modelo energético para la instalación de sistemas solares fotovoltaicos interconectados a la red con capacidades desde 1 kW y menores a 0.5 MW, mediante la implementación de sistemas de generación distribuida que contribuyan a la sustentabilidad energética de cualquier región del mundo, considerando caso de estudio la ciudad de Nuevo Laredo. La ciudad está situada sobre la región de la cuenca de Burgos y cuenta con amplios yacimientos de gas y petróleo, cuya extracción demanda altos consumos de energía. Siendo necesario el desarrollo de proyectos energéticos, para proveer de energía a muchas empresas que pudieran instalarse en la ciudad para extraer estos recursos del subsuelo. Siendo pertinente, desarrollar un modelo energético que describa metodológicamente la existencia de condiciones óptimas para implementar masivamente sistemas solares fotovoltaicos interconectados, dado el alto índice de radiación solar de la región. La metodología empleada es del tipo descriptivo, ya que el modelo propuesto se construye integrando en un solo bloque y describiendo a la mayoría de las variables que intervienen en un sistema solar fotovoltaico de generación de energía eléctrica, siendo además correlacional y cuantitativa por las mediciones, el análisis y la comparación de las variables de radiación solar, meteorológicas y eléctricas, que afectan u optimizan el desempeño del sistema fotovoltaico. Conteniendo sesgos cualitativos al incluir aspectos sobre usuarios, empresas, proveedores, normatividad y personal calificado relativo al área energética. Los resultados obtenidos aplicando metodológicamente el modelo energético propuesto, permitieron inferir que la región bajo estudio (en este caso Nuevo Laredo) si cuenta con las condiciones necesarias y suficientes para instalar sistemas solares fotovoltaicos. Concluyendo con la utilidad del modelo para determinar de manera sencilla, la viabilidad de instalar sistemas fotovoltaicos en cualquier región, integrando en un reporte técnico toda la información descrita en el modelo desarrollado.

Existe en el país el escenario de mercado lleno de este producto, con varias marcas y jugadores fruto de la dependencia al 90% de las importaciones y se han registrado muchos inconvenientes en su proceso de comercialización y ventas. Tras un cuidadoso análisis, se identificó que este problema se debe a la falta de un programa adecuado de control de calidad de estos productos. En términos generales, el presente estudio tenía como objetivo desarrollar un sistema de gestión y seguimiento de la calidad de los aceites lubricantes para automóviles aplicable al contexto angoleño. A través de una investigación cualitativa y como resultado de un estudio exploratorio, que incluyó entrevistas y estudios de campo, a las partes interesadas en las áreas de producción, importación, inspección, comercialización y fiscalización de combustibles y lubricantes, este estudio presenta una propuesta de programa de monitoreo de aceites lubricantes automotrices con el fin de garantizar la calidad del producto. Una vez hecho esto, los resultados permitieron identificar los inconvenientes del modelo actual de gestión de la calidad de los combustibles y lubricantes y, en consecuencia, sistematizar una propuesta de modelo para un "Sistema Integrado de Monitorización de la Calidad de los Lubricantes" con el potencial de ser extendido también a la monitorización y gestión de la calidad de otras clases de aceites lubricantes y combustibles. Tras describir su funcionalidad, sus principios y las condiciones de estructuración para el funcionamiento de la respectiva propuesta, el estudio recomienda al Ministerio de Recursos Minerales, Petróleo y Gas de la República de Angola que haga suya la idea de crear e implementar el sistema aquí propuesto

Higher education institutions' wireless networks have different roles and network requirements, ranging from educational platforms and informative consultations. Currently, the inefficient use of network resources, poor wireless planning, and other factors, affect having a robust and stable network platform. Different authors have investigated the various strategies for the optimization of wireless infrastructures. Still, most of the cases studied aim to improve traditional performance variables without considering maximizing the level of user satisfaction, which represents a flaw that this research paper hopes to solve through SDWN and a predictive model. The authors will determine an appropriate methodology to estimate the user's level of satisfaction through an algorithm or predictive model based on nonlinear multiple regression supported on network performance variables, making a characterization of the project's environment analyzing the wireless conditions. The investigation phases will follow the life cycle guidelines defined by the Cisco PPDIOO methodology (Prepare, Plan, Design, Implement, Operate, Optimize). As a result, it is expected that the project will be the beginning of academic research that will help create strategies to optimize the WiFi network of any educational institution to maximize user satisfaction. In short, the optimization process provides the network with differentiating factors through a modular design with variable modification of parameters according to the users' requirements and needs.

The collection of water is proposed from the design of
contour borders and half moons, green infrastructure
measures, to reduce surface runoff and increase the
availability of water for vegetation. The contour and
crescent ridges have land ridges with a trapezoidal section,
which follow the contour lines, to compartmentalize the
slope into smaller hydrological units, the ends of which are
located on contour lines. With the data of maximum
rainfall every 24 hours and parameters of Gumbel's Law
modified, the equations of maximum daily rainfall height
(hdT), rainfall height for a duration ´´t´´ (htT), and the
Intensity Duration Frequency curve (ItT), for a duration of
t <2h. Then considering the values of basic infiltration,
vegetation cover, soil type and hydrological condition, the
curve numbers were determined for different soil moisture
conditions, later the separation length (L) between the Half
Moons, and the borders was calculated. in contour, which
were designed by means of 10 configurations between
diameter and height, for the two infrastructures, being in
Copacabana Valle, the greatest separation distance.

La enfermedad renal crónica terminal es un problema de salud a nivel mundial que afecta no solo a los pacientes con esta patología clínica sino también a su entorno; es decir, en términos generales, puede tener efectos indirectos en el ámbito familiar entre los que se encuentran el cambio de estilo de vida y la calidad de atención al paciente dializado entre otros. Aquí cabe mencionar que existen guías clínicas para el manejo adecuado de estos pacientes; sin embargo en el caso del territorio chileno, si bien existen guías clínicas, no se evidencia el uso de modelos teóricos de enfermería que consideren no solo prestaciones terapéuticas específicas de diálisis, sino también otros factores, tales como las necesidades psicológicas y sociales relacionadas con el paciente y su entorno. Objetivo: Diseñar un modelo que sirva para determinar algunos parámetros en un nuevo formato tomando como base el modelo de sistemas de Betty Neuman, el cual ayude en el quehacer diario del personal de enfermería. Método: La investigación corresponde a un estudio de caso, con diseño pre experimental. La primera etapa involucro capacitar a las enfermeras que estaban encargadas de la atención a pacientes sobre el modelo a implementar. En este sentido, se realizaron varias determinaciones como son; 1) la aplicación del cuestionario KDOQL-36 a los pacientes, antes y después de implementar el modelo. 2)Además se aplicó encuesta para medir percepción respecto a éste a enfermeras y pacientes. 3) Se realizó análisis cuantitativo mediante estadística descriptiva e inferencial utilizando el programa SPSS v.21. Resultados: La implementación de esta nueva teoría de rango medio de enfermería en la atención del paciente dializado, logró mejorar su calidad de vida, así como también permitió unir la teoría a la práctica clínica. Además se logró una apropiada aceptación de ésta por parte de los enfermeros y pacientes.

Resumen. El estudio consistió en determinar el efecto del compost de E. crassipes en la calidad de las plantas en vivero de T. cacao, conocer los porcentajes de compost apropiados para su implementación y determinar niveles de plomo (Pb), arsénico (As) y mercurio (Hg) en plantas de E. crassipes, compost y plantas de T. cacao. Se utilizó un diseño completamente al azar, con 5 tratamientos, 5 repeticiones con 48 plantas cada uno. Se usó compost de E. crassipes en porcentajes de 10%, 20% y 40% mezclados con tierra en 90%, 80% y 60%. Los tratamientos se identificaron como: T1 (T10:90), T2 (T20:80), T3 (T40:60), un tratamiento relativo T4 (TR, 100% tierra y fertilización química) y un tratamiento testigo T5 (TT, 100% tierra). Los resultados del ANOVA demuestran que existe diferencia estadística significativa de los tratamientos en la calidad de las plantas de T. cacao para el diámetro, Índice de Calidad de Dickson (ICD) y peso seco total. Los T1, T2, T3 y T4, fueron estadísticamente superiores al tratamiento testigo T5 (TT) en esas variables. La altura de planta, índice de esbeltez, y relación peso seco aéreo-peso seco radicular, no presentaron diferencia estadística a un nivel de significancia de 0.05. La traslocación de Pb a plantas de T. cacao fue inexistente. Las plantas del T3 (T40:60), mostraron amarillamiento clorótico y síntomas de enfermedades en los 45 a los 90 días de germinadas. Se recomienda usar porcentajes de compost de E. crassipes no mayores al 20%, para plantas de T. cacao en vivero.

Las plataformas y medios digitales están cada vez más presentes en la sociedad y por ende en las organizaciones empresariales. Los profesionales de la educación no son ajenos a esta situación y se aprovechan de estas tecnologías y a la vez se enfrentan al reto de adaptarse de manera constante al avance tecnológico y a las repercusiones que tiene en su desempeño. En este ámbito, el desarrollo de las plataformas digitales para aprendizaje se ha visto impulsado por la confluencia de múltiples factores entre los cuales se destaca el avance tecnológico, la disponibilidad de dispositivos, las nuevas generaciones de nativos digitales. La formación e-learning es un ejemplo del auge de estas plataformas digitales pero todavía nos encontramos tecnologías más avanzadas como la realidad virtual, tecnologías inmersivas, Internet de las Cosas, etc. que también tienen o tendrán cabida en el entorno educativo. Nuestro proyecto nace con el objetivo de aportar valor a este escenario alrededor de los conocidos como entornos virtuales. Desde el sector educativo universitario, se ha sabido ver la oportunidad de la aplicación de estas técnicas a los procesos formativos del alumnado, inicialmente desde las ramas de la ingeniería que se dedicaban al propio desarrollo de estas tecnologías, y posteriormente desde las disciplinas más afines al aprendizaje cognitivo humano como pueden ser la Psicología o la Pedagogía que buscan evaluar estas técnicas respecto a otras metodologías más clásicas presentes en la Educación. Sin embargo, como se puede extraer de diversos artículos científicos que aplican estas modalidades para la educación, persisten carencias para que los docentes de cualquier área/disciplina dispongan de herramientas lo suficientemente intuitivas para crear los entornos virtuales para simular los entornos profesionales de su especialidad. El diseño de herramientas para docentes (T. Budai, 2019), ayudaría a evitar estas barreras de entrada para extender su uso. Por otro lado, aunque las publicaciones que aplican este tipo de tecnologías a la enseñanza (N. Pellas, 2020), la formación profesional (H. B. Andersson, 2020), o incluso a aprendizajes cognitivos (E. Rho, 2020), consideran que son muy positivas desde el punto de vista pedagógico (H. Ardiny, 2018), se reclama una necesidad en cuanto a establecer unas métricas y metodologías de evaluación apropiadas al proceso de enseñanza-aprendizaje (A. Dengel, 2018), (A. Christopoulos, 2019). En algunos casos se habla la gran asignatura pendiente, que es el tema de la evaluación. Cuando los docentes intentan implementar instrumentos de evaluación basados en entornos digitales, encuentran dificultades para hallar el equilibrio entre la evaluación, la metodología y el uso de los nuevos medios. Ante este escenario, el proyecto pretende diseñar y desarrollar un entorno virtual experimental para la educación práctica universitaria con énfasis en el sistema de evaluación del proceso de aprendizaje y el control de calidad.

Las instituciones educativas constituyen el escenario propicio para generar cambios sustanciales en la sociedad. Es allí, donde se forman jóvenes que tendrán en sus manos el futuro de los pueblos. En tal sentido, en cada directivo recae gran responsabilidad como rector garante de estos espacios académicos que debe propiciar la calidad educativa como proceso eficaz de cara a las necesidades del contexto. Desde este punto de vista, esta investigación doctoral tuvo como propósito formular líneas estratégicas gerenciales basadas en el liderazgo pedagógico y la gestión escolar del directivo para mejorar la calidad educativa de las instituciones educativas fiscales de la ciudad de Quito. Este trabajo se suscribe a una investigación de corte mixta con una mirada complementaria de los paradigmas positivista e interpretativo crítico, apoyada en un estudio de campo de carácter descriptivo correlacional, inferencial con el coeficiente de correlación de Pearson, un modelo de regresión lineal múltiple o multivariante, así como un análisis hermenéutico del fenómeno social - educativo en el que se insertan las instituciones educativas. A tal efecto la muestra estuvo constituida por 217 directivos de los Distritos Educativos y por 374 docentes pertenecientes a la Coordinación Zonal de Educación No. 9 dentro de la división administrativa del Ministerio de Educación del Ecuador. Los sujetos se seleccionaron a través de un muestreo por conglomerado. La técnica para la recolección de información es la encuesta a través de un cuestionario autoadministrado contentivo de las dimensiones e indicadores de las variables en estudio. Los resultados del estudio determinaron la correlación significativa positiva entre diferentes dimensiones de las variables, así como la incidencia de las variables independientes gestión escolar y liderazgo pedagógico, sobre la variable dependiente calidad educativa. De allí, que se concluye que las hipótesis formuladas son correctas y, en consecuencia, se aceptan. Finalmente, se describen las implicaciones y limitaciones, no sin antes presentar una propuesta de líneas estratégicas gerenciales para abordar los hallazgos encontrados en la realidad estudiada.

Ante la adopción creciente del modelo ISO 9000 por las Empresas Industriales de Productos Algodoneros Textiles en Bolivia (EIPAT), para abordar eficazmente un contexto dinámico y, al no poder visibilizar cambios representativos en su desempeño; además, considerando el impacto de un Liderazgo sólido en los colaboradores y su repercusión en los procesos y la organización, y por último, siendo uno de los principios de gestión de la calidad el Liderazgo; se buscó establecer la relación entre éste y el Éxito Organizacional (EO). Se establecieron 2 objetivos: (1) Determinar si los niveles de dirección ejercen las acciones de Liderazgo recomendadas por el modelo ISO 9000 y, (2) Determinar la relación que existe entre el Liderazgo que se ejerce en cada uno de los niveles de dirección y el EO. La hipótesis alterna fue “Las acciones para ejercer Liderazgo influyen positivamente en el Éxito de las organizaciones con certificación ISO 9001”; y la nula “Las acciones para ejercer Liderazgo no influyen positivamente en el Éxito de las organizaciones con certificación ISO 9001”. El instrumento de recolección de información fue validado por expertos en metodología de la investigación y el estadístico Alfa de Cronbach. En el análisis de los datos se utilizó las medidas de tendencia central y variabilidad para lo descriptivo y el coeficiente de correlación de Spearman para lo correlacional; lo cual permitió determinar que existe una relación positiva fuerte y moderada entre las variables de estudio; así como, que los niveles de dirección medios ejercen con mayor frecuencia dichas prácticas.

Today’s processes are dynamic, in particular how customers purchase products and/or services from financial institutions. Therefore, organizations face the challenge of establishing business strategies focused on the customer and building long-lasting relationships. This implies accelerating the needs of a digital transformation both toward the customer and in internal processes. A framework for risk management, applicable to digital transformation projects, is presented under an agile approach to manage and manage operational risks. Thus, through a methodology based on the application of a set of Scrum best practices, it is integrated into the current risk management tools of a banking institution. The results are scalable and extensible to Financial and Governmental Institutions.

El presente artículo pone de manifiesto el conocimiento técnico eléctrico de funcionarios vinculados en el proceso productivo, tomado de un segmento de las empresas pesqueras de Chanduy, seleccionadas bajo el criterio de estar legalmente constituidas y de su consumo de energía eléctrica. Mediante la aplicación de una encuesta de diagnóstico, se evidenció la existencia de una brecha de conocimientos técnicos, lo que llevó a elaborar una metodología, así como también temas de cultura energética. Posterior a la capacitación, se realizó un proceso de retroalimentación y una evaluación mediante un test de conocimientos, en el que un 75% de los evaluados presentaron un rendimiento favorable, un 17% presento un rendimiento poco favorable y un 8% un rendimiento desfavorable. En los casos poco favorables y desfavorables se recomendó que el empleador realice acciones de capacitación y fortalecimiento en los temas necesarios. Finalmente, se diseñó un plan de trabajo con dos escenarios, uno para el reclutamiento de nuevo personal y el segundo, para aquellos que ya son parte del proceso productivo de la empresa, con la finalidad de fortalecer las habilidades individuales y colectivas en función a las capacidades y necesidades, con una retroalimentación que también permita al empresario conocer las debilidades y fortalezas para optimizar los procesos productivos, en función a la reducción del consumo innecesario de energía, minimizar el gasto de mantenimiento correctivo y tener una planificación adecuada del proceso de mantenimiento.

El consumo de energía a nivel mundial continúa incrementándose debido al aumento demográfico y desarrollo tecnológico, sin embargo, el 73 % de la energía utilizada proviene de fuentes fósiles altamente contaminantes para el planeta y cuyas reservas mundiales se reducen aceleradamente, utilizando únicamente un porcentaje menor de energías limpias o renovables que mitiguen el calentamiento global, el cambio climático y aseguren la sustentabilidad energética mundial. Conscientes de esta problemática nacional y mundial, se propone un modelo energético descriptivo que incluya metodológicamente los pasos a seguir para determinar la viabilidad de instalar sistemas solares fotovoltaicos en cualquier región del mundo, mediante el análisis del recurso energético renovable disponible, de las variables medioambientales y eléctricas y, de los recursos humanos, materiales y financieros. El modelo propuesto se desarrolla y diseña mediante la recopilación, integración y análisis de diversas fuentes y trabajos de investigación relacionados al tema, conjuntado como un sistema integral que muestra gráficamente y describe los bloques de información que deben considerarse. Como un caso particular de estudio el modelo se aplica en Nuevo Laredo, para demostrar que existen las condiciones necesarias para instalar sistemas fotovoltaicos. Se considera la medición de variables in situ mediante instrumentos especiales y las obtenidas de bases de datos o software especial, se analizan y se comparan con normas, especificaciones de fabricantes, regulaciones y parámetros de referencia, lo que permite determinar la viabilidad de la región para instalar sistemas solares fotovoltaicos. Finalmente, la aplicación del modelo requiere elaborar un reporte técnico de los resultados obtenidos.

Kinetic rigidity of several polymers such as 2,6-bis(3-aminophenoxy)benzonitrile/4,4′oxydiphthalic anhydride (β-CN)APB/ODPA, poly[(2,2-dimethyl-1,3-dioxolan-4-yl)methyl acrylate)] (PACGA), and diglycidyl ether of bisphenol A (DEGEBA) was studied. Rigidity parameter D, Vogel’s temperature T0, and the activation energy Uα (Tg) for the glass transition were evaluated through Vogel’s model along with relaxation data using “nonlinear” regression of Arrhenius function. The existence of certain functional groups within the structure, such as the aromatic rings, gives high level of kinetic rigidity to the structure as is the case of (β-CN)APB/ODPA and DEGEBA, while the aliphatic groups confer flexibility, as in PACGA.

Research by the World Health Organization (WHO) identifies that most two-wheeler deaths are caused due to not wearing a helmet. However, the advancement in sensors and wireless communication technology empowers one to monitor physical things such as helmets through wireless technology. Motivated by these aspects, this article proposes a wireless personal network and an Internet of Things assisted system for automating the ignition of two-wheelers with authorization and authentication through the helmet. The authentication and authorization are realized with the assistance of a helmet node and a two-wheeler node based on 2.4 GHz RF communication. The helmet node is embedded with three flex sensors utilized to experiment with different age groups and under different temperature conditions. The statistical data collected during the experiment are utilized to identify the appropriate threshold value through a t-test hypothesis for igniting the two-wheelers. The threshold value obtained after the t-test is logged in the helmet node for initiating the communication with the two-wheeler node. The pairing of the helmet node along with the RFID key is achieved through 2.4 GHZ RF communication. During real-time implementation, the helmet node updates the status to the server and LABVIEW data logger, after wearing the helmet. Along with the customization of hardware, a LABVIEW data logger is designed to visualize the data on the server side.

Currently, multilevel inverters have been increased the number of applications in the industrial sector and renewable energy sources. Among its characteristics, the most remarkable are modular design, high performance, and low harmonic distortion in the output voltage waveform. For this paper, a single-phase Cascade H-Bridge Multilevel Inverters (CHB-MLI or CMLI) topology with independent DC sources, has been selected for the case study. Analyzing three scenarios: 5-level, 7-level, and 9-level applying the concept of the Optimized Harmonic Stepped-Waveform (OHSW) and comparing the results between the Selective Harmonic Eliminated-Pulse Width Modulation (SHE-PWM) and the Optimal Minimization of the Total Harmonic Distortion (OMTHD) are also presented. To compare the results obtained with classical and nature-inspired optimization methods, three techniques are used to solve transcendental nonlinear equations for the problem of Total Harmonic Distortion (THD) minimization: Newton Raphson (NR), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO), which have been widely used for the problems of THD minimization in multilevel inverters.

Currently, multilevel inverters with an induction motor as a load are widely used in the industry. Therefore, there has been an increase in the number of studies related to the analysis of the advantages and disadvantages that are presented in the set: multilevel inverter + induction motor (MLI+IM). Exist several multilevel inverter topologies and different modulation techniques for these inverters, so it is very difficult to select the most suitable combination to improve the operating conditions of the set. This paper presents a comparative analysis of the behavior of the electrical and mechanical parameters in the set: multilevel inverter + induction motor, using four different pulse width modulation techniques to generate the switching states for the power semiconductor devices in a three-phase, seven-level cascade multilevel inverter. The objective of the comparison is to identify the modulation strategy with the best performance for the conditions established in this study.

Currently, induction motors are widely used in industry because have a high potential for efficiency improvement. Therefore, a topic of interest to the industry is to reduce the energy consumption of induction motors, as they represent almost half of the total electrical energy consumption in the world. The energy consumption of electric motors can be reduced by using motors that are more efficient and by using power converters to feed the motors, thereby enabling accurate control according to the load. The function of the power converter is to modify the intrinsic characteristics of the induction motor (speed and torque). There are different topologies of the power converter commonly called inverter for induction motors. An inverter requires a modulation strategy for its operation, there are several modulation strategies that are used in the induction converter-motor assembly. This paper presents the comparative analysis of the influence of the phase disposition modulation (PD-PWM) strategy with different modulation indices, on parameters related to the output signal of a cascaded multilevel inverter (seven-levels) as well as on the nominal working conditions of a three-phase induction motor

El objetivo de esta investigación es conocer las estructuras básicas que contienen las metodologías de proyectos y lograr una tipificación que nos permita analizar las posibilidades de complementariedad y articulación de las mismas. Metodología: A partir de la identificación de las principales metodologías de proyectos, se reconocieron tipologías según las organizaciones que las promueven; luego se seleccionaron las más representativas de cada tipo y se realizó una comparación entre los ciclos de vida y los procesos básicos de cada fase dentro del grupo tipificado; posteriormente se desarrollaron tablas síntesis que representan a cada grupo de metodologías y que reflejan el contenido común de cada fase; por último se desarrollan tablas que mostraran los contenidos en cuanto a procesos, componentes e instrumentos. Este proceso permitió una comparación a nivel grupo de metodologías, lo cual hizo posible acceder a conclusiones sobre las posibilidades de complementariedad y articulación. Resultados: el análisis comparativo develó que el grupo de metodologías asociadas a las Agencias de Cooperación cuentan con unas instancias preliminares no presentes en las metodologías propuestas por las asociaciones profesionales; por otro lado, se pudo determinar que las metodologías de las asociaciones profesionales son mucho más complejas y completas en los procesos e instrumental propuesto para las fases de implementación. Discusión: Las metodologías son en muchos aspectos complementarias, una articulación entre ellas permitirá que los profesionales que se desarrollan en la disciplina capitalicen las virtudes y potencialidades de las metodologías que no les son propias, propendiendo a una práctica profesional integral y superadora.

Ionizing and non-ionizing radiations are part of our daily life, and when organisms are exposed to them for a long time, they may experience their lethal or sublethal effects. For this reason, technologies have been created to quantify them. In this study, Internet of Things (IoT) was used through connecting gamma meters and a low-cost UV radiation device. The validation of this structure was performed with meters calibrated in certified laboratories. The validation results matched those obtained by the other devices, with an error of 2%.

Esta investigación pretende determinar la existencia o no de componentes orgánicos a partir del análisis en fragmentos de morteros del convento de San Diego localizado en el centro histórico de la ciudad de Quito - Ecuador; se realizó la investigación de nueve (9) muestras de morteros tomadas de la edificación que corresponde a la época colonial, las muestras son: de adobe, mortero de pisos y enlucidos, estos fragmentos corresponden a diferentes periodos de construcción que van desde: 1597 a 1700; la presente investigación determinó que en los morteros analizados hay la presencia del mucílago de nopal.
Para realizar una valoración se obtuvieron patrones del mucilago, para esto se tomaron dos muestras de la baba de nopal: la primera muestra fue obtenida a temperatura ambiente, la misma que al tacto es ligera y pegajosa, y la segunda muestra fue extraída por medio de cocción a una temperatura de entre 90 a 100 C°, esta al tacto es mucho más densa y adherente. Así mismo, el uso de la cal fue añadido comparando la acción de la cal viva, respecto a la cal apagada (ahogada) lo que genera plasticidad adicional en el material.
Con estos patrones se realizó la comparación del patrón obtenido de los morteros antiguos, como resultado se obtuvo que los patrones que coinciden entre sí son los espectros obtenido por cocción con el obtenido de los morteros antiguos, lo que determina que se utilizó el mucilago de nopal en la construcción en la época colonial.

El presente artículo expone parte de los hallazgos de una investigación destinada a diseñar una metodología para la elaboración de un modelo de gestión (MdG), como componente básico en la preparación y evaluación de proyectos en el ámbito del Sistema Nacional de Inversiones de Chile (SNI). La metodología utilizada fue de tipo cualitativa cuantificable. La investigación consideró el análisis de metodologías y requisitos de información para la preparación y evaluación de proyectos ex ante, la revisión de modelos en proyectos ex post, el diseño de una metodología para la elaboración de un modelo y la aplicación en un proyecto (caso), lo cual se realizó a través de entrevistas, observaciones y análisis de documentos. Los resultados obtenidos dan cuenta que las metodologías para la preparación y evaluación de proyectos de inversión pública (sociales), a diferencia de los proyectos privados, no consideran un módulo de información sobre la organización para la operación, así como tampoco los requisitos de información sectoriales. Sin embargo, los proyectos evaluados ex post revelan la importancia y utilidad de contar con un modelo ex ante para su puesta en marcha y operación ex post. Y a partir de una definición de contenidos, se diseñó una metodología para la elaboración de un modelo que permita la planificación, el seguimiento y la evaluación de un proyecto de inversión.

Se propone el diseño de una estrategia metodológica compuesta por modelos computacionales, tecnología musical y reglas básicas de composición armónica. La estrategia integra diferentes herramientas como lenguajes de programación, algoritmos y reutilización librerías para la extracción de características fuertes a las muestras producidas por un intérprete, así como la ejecución de procesos estocásticos discretos que generan melodías acotadas por reglas básicas de composición de música Pop. Las melodías generadas son convertidas en series que posteriormente son reproducidos de forma controlada, por un dispositivo MIDI (Musical Instrument Digital Interface)y acotadas por reglas de composición musical que contribuyen a disminuir la monotonía melódica. Para garantizar la integración de todos los elementos como un sistema que genera iteraciones, se utilizan protocolos de control abierto entre lenguajes de programación y herramientas que permiten la interconexión y comunicación entre los diferentes componentes tecnológicos que conforman la estrategia. Una vez concluido el proceso de generación de fragmentos melódicos, estos son transmitidos aun gestor de audio y copiados en cada canal del gestor en un formato de tipo estándar MIDI. Esta información, además de ser editable, brinda la posibilidad al productor de reutilizar estas pistas como materia prima de trabajo para generar mayores escenarios y posibilidades creativas, cuando se desarrolla un proceso de producción de música Pop.

La investigación utiliza los métodos cualitativo y cuantitativo dentro de un mismo estudio, lo cual permite realizar inferencias como resultado del análisis de la información recolectada. Asimismo, explica las relaciones causales existentes entre las variables intervinientes en la problemática y, a su vez, se orienta a la solución de un problema. La investigación trabaja con data de dominio público, real, y explora los pocos estudios de carácter científico orientados al abastecimiento de combustibles líquidos en el Perú para luego desarrollar un diseño que somete a prueba las hipótesis causales. Adicionalmente, establece la existencia de correlación entre las diferentes variables involucradas en el problema. El desarrollo del análisis de la situación problemática siguiendo la metodología de la dinámica de los sistemas blandos (Soft System Dynamics Methodology) permite identificar las variables involucradas tomando en consideración que cada individuo tiene su propia percepción e interpretación del mundo, por lo cual tendrá también su propia percepción e interpretación de una situación problemática en particular. Ello permite una adecuada definición del problema y las situaciones de conflicto o factores críticos que se presentan en el abastecimiento de GLP, así como la identificación de las restricciones y alternativas de solución. El uso del análisis multivariante mediante la generación de un modelo de ecuaciones estructurales permite identificar los factores de impacto significativo en la problemática analizada.

Esta investigación se derivó de una parte de la base teórica de la tesis de maestría del autor, desarrollada en conjunto con el Programa de Maestría en Diseño, Gestión y Gestión de Proyectos, en la Universidad Internacional Iberoamericana, UNINI-México (UNINI-MX). El autor tiene experiencia en proyectos en el sector de la construcción, su compatibilidad y enseñanza del software específico utilizado en este segmento, y se motivó al observar el contexto en la práctica y la vergüenza personal. En otros países, es una realidad, y no una novedad, aprobar los puntajes de los proyectos de construcción, en relación con sus criterios de construcción, antes de proceder a su logro. También es digno de mención que los proyectos que resultan del modelado de la información de construcción (proyectos BIM), entre otros avances tecnometodológicos entrantes de manera exponencialmente creciente en la velocidad de ocurrencia, calidad y cantidad de colaboraciones, exigen cada vez más cambios en los paradigmas en la construcción civil, pero facilitan la extracción de datos que pueden evaluarse, en relación con su capacidad de construcción, de forma automatizada. El propósito de BIM no debe ser solo la automatización de los resultados gráficos-textuales. Este trabajo buscó conceptualizar, con base en la literatura y las experiencias, cómo y cuándo extraer información de proyectos BIM que buscan automatizar la Evaluación de la Constructibilidad del Edificio.

Es una tesis doctoral basado en la evolución del sistema nacional de innovación del Perú, despejando las dudas acerca de que el crecimiento que ha tenido desde la década de los 6o en adelante no se sabia si su crecimiento había sido sustentable o no. Mediante este trabajo de investigación realizado se llego a despejar las dudas con respecto al crecimiento llegando a la conclusión de la hipótesis de que el crecimiento del Perú no ha sido sustentable para que sea sustentable tiene que haber hecho mayores inversiones económicas en innovación ya que la teoría lo dice que la innovación es el motor del crecimiento Perú no lo ha hecho por lo tanto estamos frente a un milagro económico.

Un Modelo de Madurez de la Gestión de Proyectos contribuye a que las organizaciones midan y maduren sus prácticas en gestión de proyectos, programas y portafolios, a través de la definición de conocimientos mejoras en sus procesos. En México, existen estados con mayor crecimiento en el desarrollo de nuevos proyectos, como se ha visto en los últimos 20 años en el estado de Baja California Norte. El observatorio nacional reportó que la población de profesionistas en el estado alcanzó 305,374 de personas (SNE, 2020). Por consiguiente, se pretende conocer si este sector de la población conoce o aplica algún modelo de madurez en su trabajo. Por lo anterior, se propone un nuevo modelo de madurez que combina las fortalezas de los modelos más conocidos en la literatura y propone un plan de acciones estratégicas encaminadas hacia la madurez. Se analizó el nivel de madurez de la gestión de proyectos y de las competencias individuales, grupales e institucionales de esta población en el estado por medio de una encuesta multidimensional. Para comprobar su validez, se aplicó el análisis factorial exploratorio. Se encontró que los conocimientos en los procesos de la gestión de proyectos cuentan con un nivel 3 de madurez. Sin embargo, la misión, visión y las competencias institucionales apenas lograron un nivel 2. Lo que sugiere que las gerencias bajacalifornianas deben trabajar en esos aspectos. La nueva cultura propone un plan de acciones que se alinee con las estrategias y fomente la madurez en cualquier organización.

El uso de materiales plásticos se ha incrementado enormemente en estos últimos años. Actualmente hay una gran cantidad de compañías industriales y domésticas que manufacturan sus productos usando el proceso de soldadura de termoplásticos con la tecnología de soldadura por alta frecuencia (HF). Pero al inicializar sus procesos para manufacturar productos, realizan los ajustes con el método de "prueba y error " hasta obtener los parámetros óptimos con los que se operarán los equipos de manufactura. Esto conlleva una serie de gastos que impactan el costo, calidad del producto y daño al medio ambiente por el desperdicio de productos descartados. La producción mediante procesos de soldadura de termoplásticos usando el sistema por alta frecuencia (HF), es parte integral de la mayoría de los principales procesos de manufactura. El propósito de la metodología es proponer el desarrollo de procesos óptimos de soldadura de materiales termoplásticos (EVA y EVA / EVOH) utilizando el sistema de soldadura de alta frecuencia (HF), aportando un beneficio de reducir o eliminar la pérdida de tiempo, recursos, desperdicios de materiales, gastos innecesarios, obstáculos y errores, llegando a la meta del proceso. Los resultados para la respuesta muestran que la variable de presión tiene un Cpk de 1.67, (equivalente a un proceso de 5 Sigma). En adición, la metodología permite obtener los parámetros operacionales del proceso de soldadura termoplástica en control, confiable y predecible. Permite tener un proceso que pueda producir productos de calidad para seguir siendo competitivos en un mercado global en crecimiento.

Reliability predictions are routinely performed according to mission profiles, in photovoltaic applications including at least irradiance and temperature. This paper is aimed at assessing the necessity of including humidity meteorological data in the mission profile. A DC/DC soft-switching converter rated at 1 kW, and aimed at PV applications is selected as case study. Its reliability is predicted using FIDES guide, using seasonal mission profiles for eight different sites with climates ranging from tropical-humid to hot and dry. The prediction results are contrasted, assuming that the most failure-prone converters are those at the highest temperature. The results corroborate that the thermal stress factor has a large impact on the increase in the failure rate of semiconductor devices. Nevertheless, humidity also has a noticeable impact on the failure rate, contributing with 30% in the transistors, with 6% in the diodes, and in minor proportion in the passive devices. The impact of humidity is larger when it occurs simultaneously with sustained, high temperatures, and it was found that neglecting humidity might underestimate the failure rate by as much as 35% in hot, humid sites. Therefore, detailed humidity meteorological data should be included in the mission profile.

As escolas particulares na cidade de São Paulo têm demonstrado elevado nível de qualidade na formação dos alunos. Esse fato é comprovado pelo alto índice de aprovação dos alunos que concluem o ensino médio em vestibulares nas renomadas universidades brasileiras e do exterior. Pesquisas realizadas pelos meios de comunicação (jornais impressos e televisivos) tentaram sem sucesso estabelecer critério ou parâmetro que possa ser apontado como o principal fator do recente sucesso dessas escolas. Além do visível investimento na formação de professores “especialistas” um ponto em comum chama a atenção: o alto investimento em tecnologia.
O uso de padrões para gerenciamento de serviços de tecnologia da informação não é novidade no Brasil, no entanto é notória a falta de informações sobre a aplicabilidade desses modelos nos diversos segmentos da indústria, comércio e serviços. Especificamente em escolas particulares os indicadores de uso de modelos de gerenciamento de serviços de tecnologia da informação são praticamente inexistentes.
A partir dessa perspectiva que o estudo é orientado. O objetivo principal é realizar um levantamento dos modelos de gerenciamento de serviços de tecnologia da informação praticados nas escolas particulares da cidade de São Paulo e após a coleta dos dados efetuar um cruzamento das informações com os níveis de satisfação dos clientes internos (em específico, os coordenadores pedagógicos) de cada instituição para que seja possível entender a relação entre os altos níveis de qualidade das escolas e os modelos de gerenciamento de serviços de tecnologia da informação aplicados nessas instituições.
O trabalho iniciou com levantamento bibliográfico e estabelecimento da base conceitual para que fosse possível realizar a análise do contexto no qual o objeto de estudo está inserido. Foi realizada uma pesquisa com duas variações, uma para profissionais de tecnologia da informação e outra para os coordenadores pedagógicos que trabalham nas escolas particulares participantes do estudo.

The high level of electrical energy consumption of induction motors widely used in the industrial sector has increased interest in this sector to search for strategies to improve energy efficiency in order to save energy. During the last decade, the use of power inverters for speed control system applications in induction motors has increased considerably. Its main advantage is its capacity to improve energy efficiency, which depends mainly on the modulation technique used. In this paper, a comparative analysis of the output voltage behaviour of a three-phase dual inverter using an open-end winding induction motor was performed. For the comparative analysis, four modulation techniques: 1. Sinusoidal Pulse Width Modulation (SPWM), 2. Alternative Phase Opposite Disposition Pulse Width Modulation (APOD-PWM), 3. Third Harmonic Injection Pulse Width Modulation (THI-PWM), and 4. Carrier Based Space Vector Pulse Width Modulation (CB-SVPWM), were applied. The comparison of the simulation results was carried out using the PSim software.

Many problems in nature can be solved by resorting to numbers in a particular sequence. For example, the numbers in the so called Fibonacci sequence have been successfully applied in computer science, mathematics and game theory. Another example is the triangular number sequence, which has two main applications: the handshake problem and the round-robin tournament. These two sequences can be found in the Pascal's triangle. With the aim of enhancing the waveform quality at the output of a multilevel inverter, this paper explores the suitability of the triangular number sequence to compute the commutation angles in Pulse Width Modulation switching pattern. It has been found that this approach provides a harmonic performance comparable to the results obtained with other calculation techniques such as the Newton Raphson method or Genetic Algorithm, but without the difficulty of solving the complex non-linear equation.

Se propone el diseño de una estrategia metodológica compuesta por modelos computacionales, tecnología musical y reglas básicas de composición armónica. La estrategia integra diferentes herramientas como lenguajes de programación, diseño y reutilización de algoritmos y librerías para la extracción de características fuertes a las muestras producidas por un intérprete, así como la ejecución de procesos estocásticos discretos que generan melodías acotadas por reglas básicas de composición de música Pop. Los fragmentos generados son convertidos en series que posteriormente son reproducidos de forma controlada, por un dispositivo MIDI (Musical Instrument Digital Interface). Para garantizar la integración de todos los elementos como un sistema que genera iteraciones, se utilizan protocolos de control abierto entre lenguajes de programación y herramientas que permiten la interconexión y comunicación entre los diferentes componentes tecnológicos que conforman la estrategia. Una vez concluido el proceso de generación de fragmentos melódicos, estos son transmitidos a un gestor de audio y copiados en cada canal del gestor en un formato de tipo estándar MIDI.

Conventional IP networks connect places at great distances and meet the connectivity needs of their users. To perform each of these operations, each packet must pass through various network devices, which make individual routing decisions that make centralized network management difficult. These networks have been growing both in size and complexity, each day at a higher rate, which has generated a series of difficulties in personalization, integration, security, and optimization of these. As a solution, the Software-Defined Networking (SDN) architecture [1] was created, which promises to be a dynamic, manageable, profitable and adaptable architecture, thus becoming an ideal tool to handle large bandwidths and the development and implementation of customized applications, for different types of needs on communication networks. This document shows a performance analysis between SDN and a conventional IP network configured with the EIGRP and BGP routing protocols, establishing a configuration scenario with physical network equipment and with an SDN emulator called Mininet. The research methodology is based on the guidelines of the Cisco PPDIOO methodology and is developed in the following phases: 1. Elaboration of physical network topology with Cisco equipment, performing experiments with IPv4 and IPv6, measuring variables such as Jitter, Delay and Throughput. 2. Carrying out the same experiments and tests with SDN, in a network topology with similar characteristics to those already mentioned, but with OpenFlow switches. 3. Analysis of results, for which the behavior of jitter, delay and throughput variations of both scenarios is examined to make a series of comparisons (made with statistical analysis) concerning protocol, addressing, packet size among others. Finally, it was obtained as a result that SDN has a lower delay and jitter than the conventional IP network in some cases, as well as a more favorable throughput.

En el marco del proyecto de actualización del Módulo de Diseño de FUNIBER respecto a la certificación IPMA 4.0, este aporte presenta el diagnóstico inicial de una muestra de alumnos que aún no han cursado el Módulo de Diseño actualmente disponible. Esta propuesta está basada en la metodología de investigación-acción enfocada a la educación, y tiene el objetivo de describir la autoevaluación del nivel de competencias IPMA 4.0 de 36 alumnos del módulo mencionado. La metodología utilizada es de diseño no experimental, de tipo exploratorio y con enfoque mixto, en la cual se utilizó un instrumento de medición de 29 preguntas, asociadas a las 28 competencias que señala IPMA en sus tres áreas (Perspectiva, Personas y Práctica), excepto en el caso de Trabajo en Equipo en que se plantearon 2 preguntas para evaluar una misma competencia. Los resultados obtenidos se presentan en una proyección de Análisis de Componentes Principales y gráficos de dispersión, a partir de los cuales es posible concluir que los alumnos del Módulo de Diseño en el área de proyectos que comenzaron el curso transversal en mayo 2018 siguen una tendencia de distribución de frecuencia de respuestas con máximo en el nivel Medio para un 92% de las competencias estudiadas. Para la competencia Integridad y Confianza se encontró una distribución con máximo en el nivel Alto y para Orientación a Resultados una distribución equivalente entre los niveles Bajo y Alto. Finalmente, se recomienda la optimización del instrumento de evaluación considerando herramientas estadísticas y el enfoque desde 6 elementos propuesto por Tobón en 2008.

Ibero-american International University > Research > Articles and books Abierto Inglés Seven aromatic polyamides and copolyamides were synthesized from two different aromatic diamines: 4,4′-(Hexafluoroisopropylidene)bis(p-phenyleneoxy)dianiline (HFDA) and 2,4-Aminobenzenesulfonic acid (DABS). The synthesis was carried out by polycondensation using isophthaloyl dichloride (1SO). The effect of an increasing molar concentration of the sulfonated groups, from DABS, in the copolymer properties was evaluated. Inherent viscosity tests were carried out to estimate molecular weights. Mechanical tests were carried out under tension, maximum strength ( σ max), Young’s modulus (E), and elongation at break (εmax) to determine their mechanical properties. Tests for water sorption and ion exchange capacity (IEC) were carried out. Proton conductivity was measured using electrochemical impedance spectroscopy (EIS). The results indicate that as the degree of sulfonation increase, the greater the proton conductivity. The results obtained showed conductivity values lower than the commercial membrane Nafion 115 of 0.0065 S cm−1. The membrane from copolyamide HFDA/DABS/1S0-70/30 with 30 mol DABS obtained the best IEC, with a value of 0.747 mmol g−1 that resulted in a conductivity of 2.7018 × 10−4 S cm−1, lower than the data reported for the commercial membrane Nafion 115. According to the results obtained, we can suggest that further developments increasing IEC will render membranes based on aromatic polyamides that are suitable for their use in PEM fuel cells.

Las Tecnologías de la Información y Comunicación (TIC) se han convertido en herramientas fundamentales para apoyar los procesos de negocio. No obstante, su incorporación ha traído nuevas y sofisticadas amenazas y vulnerabilidades. Por ello, la gestión de riesgos en Tecnologías de Información es un factor determinante para garantizar la continuidad del negocio. Una de las primeras actividades que se deben abordar en la gestión de riesgos, es la evaluación del contexto organizacional, que arroja como resultado una comprensión de la empresa en torno a su estrategia para gestionar riesgos y al papel que tienen los empleados en las necesidades de control. En este artículo se definen un conjunto de indicadores basados en los procesos catalizadores de COBIT para determinar el nivel de madurez del contexto organizacional para la gestión de riesgos. Adicionalmente se propone una estrategia enfocada al recurso humano para la evaluación de las amenazas y vulnerabilidades. Los resultados de su aplicación permitieron constatar que a pesar de que se definen políticas en torno a la gestión de riesgos más del 70% de los empleados no las implementa a cabalidad, por lo cual, evaluar el contexto organizacional periódicamente y con indicadores claros es fundamental.

En Costa Rica, los horticultores labran el terreno dos veces al año, con cada ciclo de cultivo, usando sistemas de labranza convencional que pulveriza la capa arable, lo que ha provocado la degradación de suelos de uso agrícola en un 28%. En la presente investigación, se estableció un diseño experimental de bloques al azar, con tratamientos de labranza cero (T1), convencional (T2) y reducida (T3) en un suelo Franco arenoso (Fa). Se determinó el contenido de materia orgánica (MO), densidad aparente (Da), conductividad hidráulica (k), resistencia a la penetración (RP) y retención de humedad (RH), antes de cada tratamiento (T0) y después de seis meses. También, se midió patinaje del tractor, la velocidad de operación y los costos de las mecanizaciones. Acorde a los resultados, se determinó la necesidad de lastrar el tractor para rotar el suelo y tener mejor eficiencia, debido al derrape del eje delantero en T2 (-34,81%). T2 mostró aumentos de MO (p<0,05), por efecto a corto plazo del corte superficial de la cobertura vegetal y Da aumentó (p<0,05) a los 30-45 cm en T1, debido a que no hubo pase de arado de cincel. Ninguno de los tratamientos cambió la condición de k moderada hasta los 30 cm de profundidad. T3, mejoró RP (p<0,05) hasta los 30 cm de profundidad debido a que solamente se hizo un pase de arado de cincel. La RH no experimentó cambios (p<0,05). En conclusión, por la ineficiencia de operación y a que no hay mejora física del suelo en el corto plazo, no es necesario labrar cada seis meses, considerando que, además, la reducción de costos que se obtendría.

Las organizaciones requieren implementar proyectos cada vez con más frecuencia para poder adaptarse a los cambios del entorno en el que operan, minimizando riesgos y aprovechando oportunidades. Este contexto exige que las Oficinas en Gestión de Proyectos (PMO) y los Gerentes de Proyectos (PM) empleen mejores prácticas para encaminar al éxito el proyecto o la cartera de proyectos. Este éxito se logrará cuando el proyecto logre presentar los entregables de acuerdo a lo establecido en la planificación inicial, de acuerdo al cronograma y presupuesto dispuestos. El ámbito tan complejo de los proyectos y su naturaleza sistémica hacen que su gestión no sea una tarea fácil. Esto lleva a una tasa de fracaso bastante alta y pérdidas muy grandes para las organizaciones. En años recientes se ha realizado un cercano seguimiento a los resultados de los proyectos, las acciones de las Oficinas de Proyectos y los Gerentes de Proyectos con el objetivo de establecer la correlación entre variables (factores del entorno de proyectos y mejores prácticas) y resultados (éxito o fracaso). Los factores más destacados que contribuyen al éxito de un proyecto son: un efectivo patrocino de alto nivel que influya de forma efectiva en la organización para la toma de decisiones a favor del proyecto; un control de alcance que permita al proyecto mantenerse dentro de lo planificado y no modifique los entregables impactando el cronograma y el presupuesto; la alineación estratégica entre el proyecto y la organización a través de la generación de valor para los usuarios clave; la inversión en talento humano enfocada en generación de profesionales con capacidad de liderazgo y conocimientos técnicos en gestión empresarial y proyectos; y la presencia de una Oficina de Proyectos que tenga un alcance amplio en la organización que sea capaz de gestionar los recursos compartidos de forma eficiente e integrada

An average content of 0.47 g of coagulant and 0.5 g of oil per gram of MO was obtained. Highly efficient algal harvest, 80.33% and 72.13%, was achieved at a dose of 0.38 g L−1 and pH 8–9 for 5% and 10% extractor solutions, respectively. For values above pH 9, the harvest efficiency decreases, producing a whitish water with 10% (NH4)2SO4 solution. The oil profile (MO and S. obliquus) showed contents of SFA of 36.24–36.54%, monounsaturated fatty acids of 32.78–36.13%, and polyunsaturated fatty acids of 27.63–30.67%. The biodiesel obtained by S. obliquus and MO has poor cold flow properties, indicating possible applications limited to warm climates. For both biodiesels, good fuel ignition was observed according to the high cetane number and positive correlation with SFA and negative correlation with the degree of saturation. This supports the use of MO as a potentially harmless bioflocculant for microalgal harvest in wastewater, contributing to its treatment, and a possible source of low-cost biodiesel.

Las radiaciones ionizantes son parte de nuestra vida diaria, pero su exposición prolongada con el tiempo produce en seres vivos efectos letales o subletales, siendo estos últimos reversibles. Lo anterior requiere un estudio sobre la radiación recibida por los seres vivos y estrategias para prevenir los efectos negativos. En este sentido, existen tecnologías disponibles para medir la radiación ionizante y no ionizante, pero su acceso es costoso, adolecen de conexiones a Internet, almacenamiento de bases de datos, información en tiempo real y la no flexibilidad de uso. En el presente trabajo se diseña e implementa un dispositivo de medición de radiaciones de bajo costo, representando una reducción hasta del 70% en el precio comercial comparado con el medidor Geiger Müller LUDLUM serie No. 307891 modelo 14C, con una eficiencia del 98% en la medición de los datos, de acuerdo a la calibración realizada por el laboratorio secundario de Colombia, autorizado por el Ministerio de Energía. El dispositivo ensamblado incluye conexión a Internet, medidores de radiaciones y hardware que con IoT contribuyen en los procesos de monitoreo y recopilación de datos. Adicionalmente, se implementó un sistema que ayuda a optimizar un dron, para transportar en zonas montañosas o de difícil acceso, se adaptó la tecnología LIDAR para la utilización de un algoritmo que permita la capacidad de detección y evasión de obstáculos en caso de que el piloto pierda comunicación con el dron. La gran innovación del trabajo consiste en realizar dosimetría en campos abiertos con equipos portátiles e inalámbricos, permitiendo en tiempo real tomar decisiones vitales en la exposición a la radiación ionizante. Los resultados entre el dosímetro análogo calibrado y el basado en IoT de este trabajo, muestran gran concordancia ya que el error relativo en promedio es del 4%, lo que garantiza la confiabilidad de mediciones realizadas con este dispositivo.

The campus wireless networks have many users, who have different roles and network requirements, ranging from the use of educational platforms, informative consultations, emails, among others. Currently due to the inefficient use of network resources and little wireless planning, caused by the growth of the technological infrastructure (which is often due to daily worries, rather than to a lack of preparation by those in charge of managing the network), There are two essential factors that truncate the requirement of having a stable and robust network platform. First, the degradation of the quality of services perceived by users, and second, the congestion caused by the high demand for convergent traffic (video, voice, and data). Both factors imply great challenges on the part of the administrators of the network, which in many occasions are overwhelmed by permanent incidences of instability, coverage, and congestion, as well as the difficulty of maintaining it economically. The present investigation seeks to propose a process of optimization of the infrastructure and parameters of the configuration of a wireless network, that allows maximizing the level of satisfaction of the users in Higher Education Institutions. In the first place, it is expected to determine an adequate methodology to estimate the level of satisfaction of the users (defining a mathematical criterion or algorithm based on the study variables [1], characterize the environment in which the project will be developed, making a complete study of the wireless conditions and implement optimization strategies with software-defined networks (SDN). SDN is a concept in computer networks that allows network management to be carried out efficiently and flexibly, separating the control plane from the data plane into network devices. SDN architecture consists of an infrastructure layer which is a collection of network devices connected to the SDN Controller using protocol (OpenFlow) as a protocol [2]. Also, SDN will study traffic patterns on the network as a basis for optimizing network device usage [3]. The phases of the research will be carried out following the life cycle defined by the Cisco PPDIOO methodology (Prepare, Plan, Design, Implement, Operate, Optimize)

El artículo está encaminado a presentar de manera científica la correlación existente entre la magnitud del riesgo con relación: a las variables sociodemográficas, a las acciones de prevención que realiza la empresa contratista, al comportamiento del personal y a la percepción del riesgo al ejecutar trabajos en alturas en actividades de operación y mantenimiento de torres de telecomunicaciones. El estudio fue realizado en Ecuador y Colombia. Este tema es de vital importancia por ser una actividad de alto riesgo que debe ser ejecutada con rapidez y precisión debido a la necesidad constante de que el mundo se encuentre comunicado a través de la tecnología. Para obtener los resultados de esta investigación se utilizó un instrumento de medición que consta de 4 bloques de preguntas, con un total de 35 preguntas. El mismo fue aplicado a una muestra que se estableció estadísticamente en 251 trabajadores de empresas proveedoras de servicios de operación y mantenimiento que realizan trabajos en alturas en torres de telecomunicaciones en Ecuador y Colombia. Para el análisis estadístico se utilizó el programa SPSS versión 25. A las respuestas recopiladas se les aplicó el análisis de Kruskall Wallis obteniendo como resultado que cuatro variables influyen en la percepción de la magnitud del riesgo: la gravedad de las consecuencias, el potencial catastrófico, la vulnerabilidad personal y la verificación del estado de los equipos de protección que cada colaborador debe llevar.

Hacia finales del año 2018 el Observatorio de Conflictos Mineros en América Latina informó de la existencia de 254 conflictos socio-ambientales activos, 273 proyectos mineros involucrados y 186 casos de criminalización de la protesta. Dichos conflictos se encuentran vinculados a operaciones mineras anárquicas, marcos institucionales debilitados y una participación social desarticulada. En este contexto, la investigación se planteó como objetivo diseñar un modelo para guiar la planificación sostenible de ordenamientos territoriales, con base en la comprensión de los espacios mineros, la gestión del riesgo de desastres en convergencia con la adaptación al cambio climático y la generación de resiliencia en Latinoamérica y el Caribe. Este fin se cimienta en los Objetivos de las Naciones Unidas para el Desarrollo Sostenible, Agenda 2030 (ODS), las premisas de la United Nations Office for Disaster Risk Reduction (UNISDR), las previsiones del Intergovernmental Panel on Climate Change (IPCC) y, las recomendaciones del International Council on Mining and Metals (ICMM). El estudio de tipo proyectivo posee un diseño de campo no-experimental de corte transversal. Correspondió un muestreo aleatorio simple con resultado de 67 ONG (N = 80). Para el diagnóstico territorial se construyó una escala mediante el método holístico-hermenéutico, ya reflejando consistencia interna (α = 0,95; p < 0,05). Se elaboró el modelo orientativo de la planificación territorial sostenible de la minería (MOPTSM), siguiendo las asociaciones significativas entre sus componentes, los impactos socio-ambientales de la minería (W = 0,936; γ = -0,867; p < 0,01), y con respecto a la gestión de riesgo de desastres (d = 0,947; γ = 1,000; p < 0,01). La investigación concluye que el Modelo mitiga directamente las causas que producen a los impactos socio-ambientales perjudiciales y promueve, con sus enfoques transversales, la reducción de riesgos en los espacios mineros.

El objetivo del proyecto SOSeas es el desarrollo de una herramienta de evaluación para predecir el riesgo dinámico de los ahogamientos en las playas. En los espacios acuáticos recreativos se espera que una herramienta informática pueda mejorar la gestión de la seguridad por parte de los socorristas y también la información de riesgo de ahogamiento para los bañistas.

En aquel caso el foco era el desarrollo de un sistema experto para la identificación, análisis y gestión del riesgo en espacios acuáticos y el diseño de una aplicación web para el registro de incidentes y accidentes. SOSeas pretende mejorar el servicio anterior integrando el sistema de información que provee el Copernicus Marine Environment Monitoring Service (CMEMS) en todo el mundo. Se pretende conseguir suficientes datos para poder nutrir a un sistema basado en técnicas de aprendizaje-máquina. La herramienta SOSeas se desarrolla para dos tipos de usuarios : gestores de playas/socorristas y usuarios recreativos (nadadores, navegantes, surfistas...). Estos usuarios podrán acceder a las condiciones meteorológicas y oceanográficas así como a información a medida sobre las amenazas de estos entornos siempre cambiantes. UNSPECIFIED UNSPECIFIED

Six aromatic copolyamides contanining phenyl groups were synthesized and characterized. The concentrations of the para-linked phenyl groups and meta-linked phenyl groups were varied systematically on the copolymers general structure to obtain a set of random copolyamides. Effect of copolymerization on glass transition temperature (Tg), tensile modulus (E), Tensile strength (σ) were measured. Changes in density were determined to estimate the effect on Fractional Free Volume (FFV). Results indicate that the substitution of para-linked phenyl group by meta-linked phenyl group causes an increase in tensile modulus E and tensile strength a decrease in Tg. The observed results are attributed to the asymmetric position of the linkages in the TERE and ISO isomers, because symmetric linkages, such as TERE, induces a higher packing of the polyamide chains while the asymmetry of ISO isomer inhibits packing causing an expansion in the FFV.

En el marco de la ejecución del megaproyecto minero Las Bambas, se tuvo regulada la operación industrial de suministro de combustible Diésel B-5 bajo el contrato CB-029-12 con una duración contractual de 5 años a partir del 2012. Se tienen como partes a Xstrata Copper, como entidad contratante, y a Petróleos del Perú – Petroperú, como entidad contratada. Por un lado, aparece Xstrata Copper como compañía minera global que opera en 19 países y es uno de los grandes productores de cobre; por otro lado, aparece Petróleos del Perú – Petroperú como empresa de propiedad del Estado Peruano y de derecho privado dedicada al transporte, refinación, distribución y comercialización de combustibles y otros productos derivados del petróleo. Adicionalmente, aparece Servosa Cargo como operador logístico de Petróleos del Perú – Petroperú que se dedica al transporte de combustibles líquidos y lubricantes hacia minas, obras de infraestructura y gran industria.
Respecto al desempeño de la operación industrial se observa hasta un 8% de bienes no entregados entre los años 2012 y 2013, incidentes de desabastecimiento intempestivo de combustible en instalaciones del cliente, y detección de incumplimiento de la especificación del Nivel de Limpieza del combustible entre otros. Estas fallas son atribuibles a que en la relación comercial no existe una metodología de gestión de proyectos.
El Project Management Institute (PMI) es una organización internacional especializada en gestión de proyectos y ha desarrollado buenas prácticas para lograr el gerenciamiento efectivo de proyectos. La presente investigación consiste en comparar las 10 áreas de conocimiento en gestión de proyectos identificadas por el PMI con aquellas aplicadas para el desarrollo del contrato CB-029-12. La aportación al estado del arte del presente trabajo es establecer una metodología a medida para el proyecto minero Las Bambas que incluya la gestión de proyectos incluyendo como una mejora la gestión de la prevención de riesgos laborales y ambientales.

Background:
Microalgae remove nutrients from wastewater with the possibility of grow in mixotrophic and heterotrophic cultures. However, the effluent quality can modify the profile of fatty acids and biodiesel quality.
Methods:
Phototrophic and mixotrophic (light / dark; 12/12 h) cultures of Scenedesmus obliquus on domestic wastewater (WW) and Artificial Wastewater (AW) was carried out to evaluate the lipid accumulation and fatty acid methyl esters profile. The microalgae was first cultivated in an enriched medium (90 mg N-NH4 L-1) and subsequently under nitrogen limitation (30, 20 and 10 mg N L-1) using a two-stage process for both culture media.
Results:
A higher cell density in enriched AW medium was obtained in phototrophic and mixotrophic culture of 19 x 106 cell mL-1 and 20 x 106 cell mL-1, respectively; than for WW (13 x 106 cell mL-1 and 14 x 106 cell mL-1, respectively). The nitrogen limitation (from 90 to 20 mg N L-1) for AW increased the lipid content by 5.0% and 17.28% under phototrophic and mixotrophic conditions, respectively and only 5% for WW in mixotrophic culture.
Conclusion:
The high Cetane Number (CN) show a positive correlation with high Saturated Fatty Acids (SFA) content and negative correlation with the Degree of Saturation (DU), suggesting a good ignition of fuel. The Cold Filter Plugging Point (CFPP) (-6.02 to -8.45 °C) and Oxidative Stability (OS) (3.53 - 6.6 h) propose to Scenedesmus obliquus as a candidate in the production of biodiesel and potential application for an integral urban wastewater treatment system.

La destilación discontinua es un proceso que se utiliza para la separación de pequeñas cantidades de mezclas de componentes que tienen un alto valor para la industria o que se deben eliminar de las corrientes de desecho por considerarse que tienen impacto contaminante en el medio ambiente. Siendo la destilación discontinua un proceso demandante de altas cantidades de energía se hace necesario conocer si la composición de la mezcla inicial tiene algún efecto en la eficiencia termodinámica del proceso, por ello, el presente trabajo considera el efecto en la eficiencia termodinámica de la concentración del componente más volátil de la mezcla de alimentación y la relación de reflujo utilizada para alcanzar el producto deseado. Las Volatilidades relativas se obtuvieron utilizando el punto de burbuja y la Ecuación de Antoine. Las volatilidades relativas se calcularon en cada período, antes de obtener el producto el proceso se llevó hasta el estado estable para enriquecer el producto hasta la máxima concentración que permite la columna.

En la actualidad existe una oportunidad para las organizaciones a partir de las capacitaciones que ellas deben brindar en diversas áreas, con énfasis en Seguridad y Salud Ocupacional (SySO) –área no excluyente-. Por diversos motivos (que atraviesan el desconocimiento general, como las formas de implementación y seguimiento) los profesionales encargados de brindarlas y los gerentes no toman las acciones necesarias encaminadas a innovar en esta cuestión, desaprovechando así el auge propiciado por el desarrollo y la accesibilidad tecnológica actual.
¿Podría una organización beneficiarse a partir de la conformación de un Entorno Virtual de Trabajo Colaborativo (EVTC) que incorpore un modelo de enseñanza dinámico que incluya instrumentos, métodos y procedimientos soportados por las Tecnologías de la Información y Comunicación (TIC) junto al conocimiento teórico necesario de diversos paradigmas educativos y herramientas que potencien la transmisión del conocimiento y genere resultados sinérgicos para todos los actores?
Para demostrarlo, se propone una modalidad de diseño metodológico enfocada a un experimento denominado puro o verdadero, que se nutrirá de un estudio de campo conceptualizado, definido, creado e implementado ad hoc en una Cooperativa ubicada en la ciudad de Concordia, Argentina para con éste obtener respuestas que permitan demostrar la correlación existente entre una correcta conformación de un EVTC que incluya un modelo de aprendizaje soportado por las TIC y la obtención de beneficios multifactoriales producto del manejo racional del conocimiento.
Logrado comprobar lo antes expuesto, y a partir de la nueva oportunidad generada, se describirán alternativas para aquellas organizaciones que decidan continuar su camino evolutivo en el manejo del conocimiento a partir de la implementación y conformación de un modelo de Gestión del Conocimiento que requiere una especial atención a factores internos que involucre a todos los estamentos y sectores de la organización.
El atravesamiento de los niveles madurativos organizacionales del uso del conocimiento otorgará beneficios aditivos en el corto o mediano plazo y sinérgicos en el largo plazo dependiendo la forma, velocidad y nivel de implementación de las actividades nucleadas y descriptas a partir de la descomposición en objetivos de la solución ofrecida de esta investigación que se nutre de la innovación como motor y que busca como fin la mejora en la competitividad como herramienta de entropía negativa.

Del 50% de la población que hace deporte de forma regular, un porcentaje muy alto lo hace solo, en casa o en lugares abiertos públicos sin ninguna supervisión o control por parte de personal especializado, lo que conlleva un cierto riesgo de sufrir lesiones y/o patologías de diferente pronósticos. Ante esta situación compleja de tener la necesidad de promover la actividad física pero intentando aminorar el riesgo de la propia práctica, se propone el desarrollo de una aplicación móvil “freemium” que fomente el ejercicio y que integre una serie de tecnologías innovadoras para incorporar inteligencia artificial que aplicará sobre unos elementos de alerta que puedan generar avisos y geolocalizar al practicante de una forma rápida y eficaz. Entendemos que el desarrollo de este tipo de negocios de carácter tecnológico y de alto grado de responsabilidad social hacia la ciudadanía incrementará el tejido empresarial de Cantabria y generará nuevos puestos de trabajo estables y de alto nivel de formación.
