In current supply chains, the use of AIDC technologies allows the information that flows to be standardized and reliable, as well as obtaining a series of advantages related to saving time and costs. In Cuba, the use of these technologies is not regulated by national laws and most companies do not use them, considering ignorance of their effectiveness as the cause. This article analyzes AIDC technologies: specifically, bar code systems and radio frequency systems, their operation and benefits of their use in supply chains. Based on the existing need, a tool was designed based on a procedure that establishes a guide for the selection of technologies to be implemented in logistics processes. The tool designed is used for Case Studies to know its application and mode of use.

Se reporta el desarrollo de un laboratorio Virtual basado en histograma para llevar a cabo experimentos sobre binarizacion de imágenes en niveles de gris. A fin de automatizar el proceso de binarizacion, se introduce un Umbral Heurístico de Binarizacion. Después de obtener el histograma de una imagen en niveles de gris el modulo calcula el umbral heurístico, extrayendo el promedio ponderado de los niveles de gris de primer plano de la imagen. A continuación se resaltan los niveles de gris en la imagen que están por encima del umbral heurístico. Aunque aún no experimentalmente óptimo, el umbral heurístico proporciona una primera aproximación hacia la binarizacion automática de imágenes en niveles de gris.

The process of home-made beer production in the malt maceration and cooking stages was controlled automatically with fuzzy logic, across different performers considering the time and temperature of the process, using 2009LabVIEW. The equipment was mainly composed of three 20 L capacity stainless steel containers (water supply, maceration and cooking), an additional hops container, a data acquisition card (PIC 16F877a micro controller), three LM35 temperature sensors and 11 on/off type performers, which were governed by a total of 47 Mandani type fuzzy rules with trapezoidal membership functions, using the method of center area for the defuzzification. The performers: electrovalves (5), pumps (2), heaters (3) and a stirrer, in approximately 4 hours, were adequately controlled in their early maceration and cooking stages. The beer obtained by automatic control with fuzzy logic in the macer...

The correct identification of timber species is a complicated task for the wood industry and government institutions regulating the different laws that ensure legal and transparent commerce. Currently, experts perform this process using the organoleptic characteristics of the wood. However, the methodology used is time-consuming and limited to environmental conditions. Moreover, it has a scalability issue since acquiring this specific knowledge and experience has a slow learning curve. On the other hand, deep learning models have evolved as possible solutions for process automation. Therefore, this paper explores convolutional neural network models suited to run on edge devices. The present study created a database with 25k images of 25 timber species from the Peruvian Amazon. We trained-validated multiple lightweight models (less than 5M). The experiments were made using a repeated stra...

The development of a Virtual Lab to perform experiments on histogram-based binarization of grey-leveled images is reported. With the aim of automatizing the binarization process, a Heuristic Binarization Threshold is introduced. Once the histogram of a grayscale input image is obtained, the module calculates a Heuristic Threshold by taking the weighted average of the foreground grey levels of the image. Next those pixels in input image whose grey levels are above this threshold are highlighted. Although still not experimentally optimum, this heuristic threshold provides a first approximation towards automatic binarization of greyscale images.

The creation of a Virtual Lab, integrated and interactive software, to perform histogram-based binarization of gray scaled images is reported. In an attempt to optimize the binarization the developed virtual lab introduces a Heuristic Binarization Threshold. At processing time, the module extracts the histogram of the input gray scaled image, and then a Heuristic Threshold is calculated by taking the weighted average of the foreground grey levels of the image. Next those pixels in input image whose grey levels are above this threshold are highlighted. Although still not experimentally optimum, this heuristic threshold provides a first approximation towards automatic optimum binarization of grey scaled images. For comparison purposes when an input image is operated on by the binarization module, it is possible to visualize up to three different binarizations on screen simultaneously, each...

Today X has become one of the most important socialnetworks for expressing opinions and interests on the web.The large amount of data generated allows automatedsystems to profile users based on gender, nationality andthematic interests. There are difficulties in this process notonly because of the short content, but also because of theambiguity and the use of several languages.The goal of this proposal is to generate a deep learningmodel using BERT that is able to identify demographic andthematic attributes from tweets. Pre-trained models of theBERT and Multilingual BERT type will be used, applied on PAN Author Profiling Task (CLEF 2019) corpora in English and Spanish.The proposed work will deepen the analysis using supervised classification data for gender and nationality classification and topic extraction through unsupervised techniques, such as LDA and BERTopic. These options include...

El presente trabajo tiene como objetivo desarrollar un sistema mecatrónico de alimentación automatizada para una granja de faisanes, con el fin de reducir el riesgo de enfermedades ocasionadas por la contaminación del alimento y la falta de control en el proceso de alimentación manual. En los criaderos tradicionales, el alimento suele distribuirse de forma irregular, lo que genera diferencias en el crecimiento de las aves y aumenta el riesgo de transmisión de agentes patógenos. El sistema propuesto integra tecnologías de identificación por radiofrecuencia (RFID), sensores de peso, infrarrojo, microcontrolador Raspberry Pi 4, y Internet de las Cosas (IoT) los cuales permiten identificar individualmente a cada faisán, controlar la cantidad de alimento suministrado y registrar los datos de alimentación mediante una interfaz de usuario. El algoritmo de control gestiona los horarios...
