La etnoecología ha sido definida como el estudio interdisciplinar de los
sistemas de conocimiento, prácticas, y creencias de los diferentes grupos humanos sobre su ambiente. En las décadas de los 60 y 70, los
primeros estudios en etnoecología se centraron…

In this paper an adaptive fuzzy decentralized
control algorithm for trajectory tracking of robot manipulators is developed. The proposed decentralized control algorithm allows the overall closed-loop system to be stabilized while making the tracking error to be uniformly ultimately bounded…

Using the underlying idea of the current-mode control, a new dynamical, sliding-mode control for the boost dc-dc converter is proposed. Such controller is easy to design, robust under load and input voltage variations, exhibits fast response, does not depend on…

The ambiguity, robustness and performance of systems becomes increasingly evident as the complexity and size increase in industrial processes. Under these circumstances, conventional control techniques such as PID control, nonlinear feedback control, LQG control and H∞ control have several disadvantages…

This document describes a general structure for the implementation of virtual tools for remote calculation through Internet. Two virtual tools for mathematical analysis
(Analys) and simulation of dynamic systems (SimWeb), supported by the Matlab c, are described. These virtual tools,…

This paper describes the implantation of a KA tool kit for use with sublanguage-specific corpora. The key idea of KA as an evolutionary process is discussed in detail. Special attention is paid to the system's attempt to avoid the pitfalls…

L’objectif de ce mémoire est de faire un état des lieux des connaissances produites sur les risques environnementaux et la vulnérabilité et appliquer ces connaissances à la ville de Kigali (Rwanda). Après avoir présenté différentes approches, nous avons retenu le…

La présente étude exploratoire examine la manifestation des schèmes de pensée chez les adolescents agresseurs sexuels. Cela s’est réalisé dans le cadre d’un stage au Centre de psychiatrie légale de Montréal. Les objectifs du stage clinique se sont précisés autour…
