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…

Discussion of the natural sciences had a foundational role in the development of the sociology of race and racism, underpinning the claim that races should, if at all, be studied as social rather than natural phenomena. Whatever its strengths, the…

Se trata de acercarnos conceptualmente a la comprensión de los elementos
básicos sobre los que las comunidades indígenas han construido su complejo sistema
de conocimientos. El logos en la cultura indígena se conforma desde una perspectiva
integral, donde participan activamente…

This study aimed at exploring how high school studentsdeal with designing an information system, for example,for a small business or a medical clinic, the extent towhich students develop as independent learners whileworking on their projects, and the factors that help…
