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…

It is estimated that 450 million people worldwide suffer from mental and behavioral disorders.
As 75% of mental disorders onset prior to the age of 24, the college years are a particularly
critical window when mental health can be promoted…

El presente trabajo describe el escenario actual de la figura del DirCom en Ecuador y propone una estrategia de comunicación orientada a posicionar y aumentar la notoriedad de la figura del DirCom en el ámbito empresarial y académico. En 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…

La concepción sistémica en la historia, permite abrir un
abanico de posibilidades en nuestro intento de interpretar y
comprender la complejidad de las dinámicas históricas. Dicha
concepción admite que los hechos y los procesos históricos se
conviertan en fenómenos irreversibles…

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,…

Building off the work of Mark Granovetter and Nancy Howell Lee, this thesis observes the employment search networks of Princeton University seniors. I interviewed thirty-five students who were actively or had recently completed searches for employment and constructed visual representations…

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…

Multi-agent systems (MAS) offer an approach to solve complex problems where data and control are inherently distributed among several agents. Normally, agents have to cope with conflicts based on inconsistent knowledge which arise when they exchange information. A relative common…
