ResumenEn este trabajo se presentan los resultados obtenidos en el reconocimiento de plagas utilizando la visión de máquina por computador como elemento de diagnóstico. La captura de las imágenes se realizó por medio de un agente robótico aéreo (drone) equipado con una cámara, lo que permitió capturar las imágenes del estado de las hojas de un cultivo de la planta conocida como 'flor de azúcar' (Begonia semperflorens). Estas imágenes fueron procesadas utilizando técnicas de visión de máquina con el fin de identificar el posible ataque de plagas en el cultivo. Las técnicas utilizadas corresponden a filtros morfológicos, difuminado gaussiano y filtrado HSL. Como resultado principal de este trabajo se detectaron perforaciones de hojas ocasionadas por el ataque de plagas, específicamente babosas, caracoles, arañas rojas y minadoras.Palabras claves: Procesamiento de imágenes, detección de plagas, monitoreo de cultivos, filtros morfológicos, difuminado gaussiano. AbstractNowadays, an important element in farming, is the use of technology, based on the analysis of the different factors that affect the succesfull development of the crops. The results are presented in the recognition of pests, in this work a computer machine vision, as a diagnostic was used. The images capturing were doing with a robotic air agent, equipped with a camera, capturing images of the state of a crop of a plant called 'Flor de azúcar' (Begonia semperflorens). These images are processed using machine vision techniques to identify the possible attack of pests on the crop. The techniques used are morphological filters, Gaussian blur filter and HSL. The main result of this work was accomplished, perform the detection of the perforation of the leaves as a result of pest attack, specifically slugs, snails, spider mites and leafminers.

Background:Reported cases of uncontrolled use of pesticides and its produced effects by direct or indirect exposition, represent a high risk for human health. Therefore, in this paper, it is shown the results of the development and execution of an algorithm that predicts the possible effects in endocrine system in Fisher 344 (F344) rats, occasioned by ingestion of malathion.Methods:It was referred to ToxRefDB database in which different case studies in F344 rats exposed to malathion were collected. The experimental data were processed using Naïve Bayes (NB) machine learning classifier, which was subsequently optimized using genetic algorithms (GAs). The model was executed in an application with a graphical user interface programmed in C#.Results:There was a tendency to suffer bigger alterations, increasing levels in the parathyroid gland in dosages between 4 and 5 mg/kg/day, in contrast to the thyroid gland for doses between 739 and 868 mg/kg/day. It was showed a greater resistance for females to contract effects on the endocrine system by the ingestion of malathion. Females were more susceptible to suffer alterations in the pituitary gland with exposure times between 3 and 6 months.Conclusions:The prediction model based on NB classifiers allowed to analyze all the possible combinations of the studied variables and improving its accuracy using GAs. Excepting the pituitary gland, females demonstrated better resistance to contract effects by increasing levels on the rest of endocrine system glands.

This paper compares the performance of three micro-controlled architectures in the implementation of a fuzzy controller, these correspond to a PIC18F2550, a MSP430G2452 and DSPIC30F4011. In order to establish which of them offers
