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…

Following the deaths of Victoria Climbié and of Peter Connelly (Baby P) the media has raged about social work competence, the public have expressed dismay and the government has responded with proposals designed to alter practice procedures. Altering procedures gives…

Investigates informal leisure uses of technology, including developing home pages, building special interest sites, surfing the Net and participating in electronic communities.

Tennis is a sport that is characterized by intermittent dynamics, with intervallic moderate and high-intensity efforts due to repetitive actions of short-duration and high intensity. This review analyzes aspects such as the game's temporal structure, oxygen consumption, heart rate, lactate…

Les élèves dyslexiques éprouvent de grandes difficultés à lire et à écrire. Leurs difficultés en production orthographique sont reconnues pour être persistantes. Elles peuvent être expliquées par un déficit des procédures phonologiques. Or, pour orthographier une langue alphabétique comme le…

En los momentos actuales, la enseñanza de la geografía y la historia, adolece de estrategias eficientes para la formación pedagógica, geográfica e histórica de los docentes en todos los niveles, lo cual genera una gran diversidad de problemas, no solo…

En el desarrollo de la línea de investigación “Formación y consolidación
de una comunidad de docentes investigadores en las ciencias sociales y en la
ciencias de la educación”, se viene diseñando, ejecutando y evaluando proyectos
de investigación referidos a la…

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,…
