Las redes neuronales artificiales son útiles para procesar datos con información incompleta para obtener una salida deseada. En los sistemas de medición de robots manipuladores, solo se toman muestras cuantificadas de la posición y, por lo tanto, no se puede ejecutar en un tiempo razonable algoritmos deterministas para extraer los parámetros del robot. En el estado del arte, se abordan algoritmos de extracción de parámetros basados en la suposición de que no existe la cuantificación de las señales del movimiento del robot y que la primera y segunda derivada de la posición son muestreadas y no estimadas. En este trabajo, se propone un algoritmo basado en una red neuronal entrenada para extraer los parámetros de un determinado robot para reducir el tiempo de caracterización del robot, además, con la metodología propuesta se pueden extraer parámetros dinámicos del mismo tipo de robot con el que se ha entrenado la red neuronal.

In the development of this work we describe the design proposal of a useful tool for the monitoring of the GEM detector panels in order to measure the current consumption and in this way to know the useful life of the detector, due to in theory the GEM doesn't produce discharges but in real life there are some small discharges (nano and micro amperes) that deteriorate the detector. In this proposal it is also contemplated to design a software to analyze the interaction of electromagnetic fields within a waveguide that represents the pathways within a printed circuit board using the study of electromagnetic theory in the development of a simulator, which will allow to analyze the effects of these fields in the propagation of the signals that are obtained and to determine if the data obtained are adequate to allow their subsequent analysis.

The present investigation was carried out with the objective to study the productive and reproductive performances of dairy cattle under organic farming systems. Total 24 medium to high yielding cattle has been selected for the study, out of which 12 were reared under organic management system and 12 under conventional management system. For cows maintained under organic management system, the animals were fed ad lib quality green fodder grown organically and limited quantity (1.5 to 2.0 kg/cows/day) of concentrate mixture. Production and reproduction performance of animals of both the groups were compared. The results revealed that the reproductive performance was better in cows maintained under organic production management system than their conventional counterparts. The study on milk quality in terms of composition revealed significantly (P less than 0.05) higher fat % of milk, while lower (P less than 0.05) protein % of milk for the cows maintained under organic system as compared to those under conventional system. It can be concluded that the organic management system of dairy cows can be beneficial as depicted by better reproductive efficiency of cows with higher fat % of the milk.
