This paper presents the main challenges of an Internet of Things (IoT) platform. In this sense, an interoperability platform for IoT devices, called PIICO, is presented in the frame of an agriculture application. PIICO is a platform able to resolve interoperability between components and has the potential to be a stable IoT platform. Improvements opportunities of the main IoT PIICO components (nodes, gateway, and data analytics platform) are presented and discussed. The proposed improvements will make that an IoT platform improves its functionality, operation, security, and performance.

There are certain difficulties in differentiating between children's facial expression related to pain and other stimuli. In addition, the limited communication ability of children in the preverbal stage leads to misdiagnosis when the child feels pain, for example, post-surgical conditions. In this article, a classification approach of facial expression of child pain is presented based on models of pre-trained convolutional neuronal networks from the study carried out in a Colombian hospital of level 4 (Hospital Universitario San Vicente Fundación), in the recovery areas of child surgery services. AlexNet and VGG (16, 19 and Face) networks are evaluated in the own dataset using the FLACC scale and their performances are compared in three experiments. The results show that the VGG-19 model achieves the best performance (92.9%) compared to the other networks. The effectiveness of the model and transfer learning for the classification of facial expression of child pain shows a promising solution for the assessment of post-surgical pain.

The use of robotics vehicles in the education of children and teenagers constitutes a modern tendency of great interest in Cuba, due to the quantity of knowledge that provides and the variety of disciplines that it integrates. The present work has as objective to evaluate the use of a teleoperated and robotic vehicle based on Arduino, in the education of children and adolescents from Cuba. It includes the study of the state of the art about educational robotics in the world and in Cuba, who allows to define the main educational activities permitted by robots and the parameters to evaluate in the vehicle of analysis. Afterwards, it carries out a description of the technical specifications of the device, which influences in the benefits obtained by the use of the vehicle. Finally, it carries out the evaluation taking into account the defined parameters in the study of the state of the art. It obtains as conclusions that the use of the vehicle with educational purposes would be very fruitful, in spite of minimum limitations that do not put directly in risk the quality of educational activities.

This article presents the development of a distributed fault diagnosis and monitoring system whose remote nodes are responsible for data collection and distributed analysis to identify problems that could lead to critical faults in industrial processes or systems. The developed intelligent remote node was implemented with MCU LPCXpresso54114 connected to a ZigBee protocol wireless sensor network through XBee communication module. The gateway node is a Raspberrry PI with HTTP communication and JSON format to the PI System industrial monitoring system database. Motor Current Signature Analysis (MCSA) was implemented and validated to identify interturn faults of induction motors. The developed platform is a tool to perform comparison and validation of analysis techniques, indicators, and fault classification, because there are different combinations that can be applied to improve diagnosis reliability, fault observability, differentiation between fault conditions, classification accuracy, tolerance to transients, sensitivity, among others.

Attention Deficit Hyperactivity Disorder (ADHD) occurs in 16% of the Colombian student population and estimates that between 30-70% of these children continue to show symptoms in adulthood. Thus, a tool is proposed for the professional to support his diagnosis according to the criteria offered by the Diagnostic and Statistical Manual of Mental Disorders (DMS). An omnidirectional platform is implemented, striking for its design, for children, adolescents and that becomes a concentration challenge for adults.With an Electroencephalography (EEG) helmet a brain wave reading is made; with the help of a Computer Brain Interface (BCI) you can have the reading of facial gestures, having said reading is implemented to control the omnidirectional platform, with the same BCI you also have the reading of concentration, stress, excitation, etc. of individuals; Thus, the professional in the area can support his diagnosis according to several factors, such as: EEG interpretation, emotional data (concentration, stress, excitement ...), and the observation of the individual. The evaluation of the patient makes the health professional, generating some challenges to overcome the platform and interpreting the different data according to their professional criteria.

In this study, a fuzzy-based PLC temperature control system was designed and implemented on a craft beer production plant. At present, the temperature-related controls of small-scale plants in Colombia are based on On/Off models, which are not very stable in the preparation of craft beer, which generates significant changes in flavor, scent and texture. Therefore, it is intended to incorporate into the craft beer industry, solutions that guarantee repeatability, minimize costs and potentiate production, for this, a three-stage fuzzy control model is carried out: design, implementation and start up; This is how a study of the plant´s dynamics is carried out, the response is determined from the data, a fuzzy controller is designed by using Matlab software, and a graphical interface in LabView for data capture and storage. The controller demonstrates stability in relation to the temperature variable, which provides repeatability and significant energy savings. Finally, it is concluded that the controller proved to be robust against major disturbances and stable at different temperatures, being a useful tool for efficiently controlling the variable.

El aparato reproductor masculino tiene una glándula ubicada debajo de la vejiga y frente al recto: la próstata. Rodea la uretra y tiene la función de producir un componente líquido en el líquido seminal. Con el tiempo, esta glándula tiende a agrandarse y bloquear la uretra, lo que dificulta la micción o la función sexual. Esta alteración se conoce como hiperplasia prostática, que se corrige con cirugía. En ocasiones se confunde con el cáncer de próstata por la similitud de los síntomas, que es frecuente en los hombres. El diagnóstico de esta enfermedad generalmente se realiza mediante una técnica manual llamada tacto rectal y una prueba de laboratorio que mide los niveles de PSA en la sangre. Es una sustancia que se encuentra en la sangre de una persona que suele tener cáncer de próstata. Además, el diagnóstico se apoya en una ecografía transrectal a través de un catéter. Este proceso integral ayuda a determinar la extensión del cáncer de próstata y a designar el tratamiento correcto. El estado de la lesión de próstata se evalúa mediante la práctica de una resonancia magnética (MRI). Es un procedimiento realizado por ondas de radio y una computadora que crea imágenes detalladas de áreas de la próstata. Analiza la condición de la próstata y determina el procedimiento o tratamiento de acuerdo con el estado de la lesión, por ejemplo, cirugía, radioterapia u observación monitoreada. Para definir qué tipo de tratamiento es fundamental analizar los diferentes estadios de la enfermedad y el Gleason Score, una medida del grado histológico, que va de 2 a 10, que indica la probabilidad de diseminación o extensión del tumor. Esta investigación se centra en el análisis y la extracción de medidas para clasificar formas de lesiones prostáticas que apoyen su diagnóstico. Considera la categorización PI-RADS, que actualmente determina la probabilidad de padecer cáncer de próstata clínicamente significativo. Para ello, se realizó un análisis utilizando una interpretación geométrica de diferentes categorizaciones de cáncer (4-5). Se realizó un procesamiento digital de imágenes de Python en T2, ADC y DWI aplicando el concepto de curva, momentos Zernike, dimensión fractal, dimensión Caliper, la curvatura absoluta total, la flexión de energía, dirección, convexidad, circularidad, compacidad, momentos Hu, dimensión, excentricidad, extensión, solidez, orientación, longitud del eje más grande, longitud del eje más pequeño, radio, centro, centroide, longitud y área.
