The development of systems with the ability to reason about change notion and actions has been of great importance for the artificial intelligence community. The definition and implementation of systems capable of managing defeasible, incomplete, unreliable, or uncertain information has…

In this paper, we present a novel model of an artificial immune system (AIS), based on the process that suffers the T-Cell. The proposed model is used for solving constrained (numerical) optimization problems. The model operates on three populations: Virgins,…

The CRISTAL project has had significant achievements in the coordination of
the research work carried out by the consortium members on renewables, the enhancement of partners’ knowledge on Renewable Energy Sources and their integrated control and use, which contributes to…

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…

Anaesthetists are a group of doctors who are at a higher occupational risk of contracting blood borne infections as they perform many invasive procedures. Practice of Universal Precautions (UP) is vital in reducing the risk of transmission. The objective of…

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,…

Emerging international research suggests that
enhancing teacher-student assessment for learning
(AfL) interactions is a key to enhancing student
learning. Planning frameworks that make explicit the
multiple dimensions of technology can be used to
extend teacher knowledge and focus interaction.
Effective…

En el siguiente artículo se exponen las ideas de Auguste Comte sobre la Filosofía de la Historia a través
de la Ley de los Tres Estados, analizando los rasgos distintivos de cada etapa, en especial el tipo de
conocimiento que…
