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…

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,…

Les plantes médicinales jouent un rôle central, tant pour la médicine traditionnelle de certaines cultures, que pour la satisfaction d’une demande commerciale, souvent lointaine. Face à la forte pression qui pèse actuellement sur les populations de plantes médicinales - due…

The specific knowledge that can be found in web sites provides a source of information which should be used by language teachers and content teachers to teach students both subject matter and language at the same time. In this paper,…

El tema central del artículo es el de cómo, desde mediados del siglo XIX,
la historiografía ha procurado explicar, en cuanto a pertenencia lingüística y
étnica a las sociedades indígenas andinas, con especial énfasis en los aportes
