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…

In big companies, managerial activities and organizational boundaries will over time hide most unevenly developed skill and knowledge distribution patterns; studying the organizations with the means of modern applied physics is thus quite difficult. People are forced to communicate along…

La présente recherche développe le projet d’écrive quatre compositions pour différents groupes d’instruments réunies autour de l’idée des quatre éléments (terre, eau, feu, air). La recherche comprend : une courte description de l’idée même de ces éléments dans la culture…

Inquiring into the suspended professionalization of the translation occupation in Israel, this article examines two types of self-presentational discourses and status strategies – that of top literary translators, on the one hand, and that of technical translators, subtitlers and non-elite…

Many studies have focused on the concept of humanization of birth in normal
pregnancy cases or at low obstetric risk, but no studies, at our knowledge, have so far
specifically focused on the humanization of birth in both high-risk, and…

The Paleontology teams at the Universidade Federal do Acre (UFAC) and the Universidade de Brasília (UnB) worked together in order to increase macro and micropaleontological knowledge of the late Miocene rocks exposed at Niterói (10º08'30''S-67º48'46,3''W), on the right margin of…

Póster presentado en 11th Mediterranean Congress in Chemical Engineering "Chemical Engineering in the Frontiers of Knowledge", Barcelona, 21-24 October 2008., This study was financial supported by the “Plan Nacional de I+D 2007-2010” of the Spanish Government (Ref. CTQ2007-66780, Spain) and…

The problem of automatic face recognition is to visually identify a person in an input image. This task is performed by matching the input face against the faces of known people in a database of faces. Most existing work in…
