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,…

Los estudios de esta tesis doctoral muestran la relación estrecha que existe en la Fenomenología del Espíritu entre el concepto hegeliano de experiencia, su concepción del absoluto y el impacto que tiene en ambos el desafío del escepticismo. La tesis…

La tesis analiza dos objeciones corrientes a la interpretación del problema de las reglas por el Wittgenstein de Kripke: el PROBLEMA DE LA OBJETIVIDAD DE LA REGLA, ¿puede un individuo estar acertado en contra de la opinión comunitaria consensuada?; y…

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…

Purpose – Information and communication technologies have became pervasive in people’s lives and in this changing world education cannot remain anchored in old-fashioned models which ignore the evolution through which society is going. This paper seeks to present the gamble…

Este trabajo realiza una reconstrucción de la trayectoria socio-técnica de la conformación de una empresa de biotecnología en el campo de la salud humana en la Argentina. En este marco, se analizan en particular las tensiones entre los diferentes estilos…

En un contexto de heterogeneidad entre las universidades nacionales argentinas, en relación a la capacidad y las condiciones de producción de conocimiento en educación, y de una fuerte concentración de la producción y los recursos humanos en las zonas metropolitanas,…

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…

The spatial variation in the composition of the tree flora of some Atlantic forest areas distributed in the East Atlantic basins, Southeastern and Southern Brazil, extended to Paraguay and Argentina, was investigated under four main aspects: (1) to evaluate the…
