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 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…

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…

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…

This work extends the semantics and implementation of fuzzy prolog presented in [VGM02] in order to include Default Knowledge capability. The new semantic allows non-uniform default assumptions and has Closed World Assumption (CWA) and Open World Assumption (OWA) as particular…

El carácter transicional de la Ría de Aveiro le confiere una riqueza florística singular, integrando comunidades vegetales típicas de las
regiones Eurosiberiana y Mediterránea. La implantación del Proyecto Desenvolvimento Agrícola do Vouga (PDAV) va a provocar una
modificación de las…
