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…

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,…

The notorious advances in textual information storage need fast and effcient tools to organize, retrieve and browse this information and tools for knowledge extraction. A very interesting way to organize specific domain information is the topic taxonomy building. Moreover a…

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…

En este ensayo se analiza el concepto de estudios sociales,
contrastándolo con la noción conceptual denominada didáctica de las
ciencias sociales; esto, con el fin de observar las particularidades de
cada categoría. Posteriormente, se plantea un esbozo de epistemología
aplicada…
