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…

Aujourd’hui, on parle du Web social. Facebook par exemple, porte bien la marque de son époque ; il est devenu le réseau social le plus convoité dans le monde. Toutefois, l’entreprise a été souvent critiquée en raison de sa politique…

Childhood obesity is heavily documented as a public health crisis in the United
States. Today, more than one-third of American youth can be medically classified as
overweight or obese. Of those children, a disproportionately high number are Hispanic.
There is…

The United States education system is not meeting the needs of today’s youth, and
this is especially the case for minority and low socio-economic status youth. Although
there are a number of policy proposals that could improve youth academic performance,

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…

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,…

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…
