Este trabajo presenta los resultados preliminares de la configuración de una red neuronal artificial (ANN), de tipo alimentación hacia adelante con el método de entrenamiento de retro-propagación para pronosticar la velocidad de viento en la región del Istmo de Tehuantepec,…

This paper describes a simultaneous planning localization and mapping (SPLAM) methodology focussed on the global localization problem, where the robot explores the environment efficiently and also considers the requisites of the simultaneous localization and mapping algorithm. The method is based…

Las imágenes por resonancia magnética pesadas en difusión son ampliamente utilizadaspara el estudio de las estructuras cerebrales dentro de la materia blanca del cerebro. Sinembargo, recuperar las orientaciones de los axones puede ser susceptible a errores por elruido dentro de…

  This paper describes an investigation of the density and distribution of phytoplankton and zoobenthic organisms carried out in the Zempoala Lake from 1998 to 1999. The data showed that the flora is made up of 29 species, distributed in…

This paper tests the hypothesis that perceived differences in Mexican identity and political interest condition social well-being and the perception of anomie. The three dimensions of Tajfel’s social identity theory was adopted to measure Mexican identity, as well as the…
