The literature suggests that the United Kingdom, in common with Europe, North America, Canada and Scandinavia, has seen significant growth in single-issue self-help/mutual aid groups concerned with health and social care issues since the 1970s, but there is only ad…

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,…

El artículo forma parte de una conferencia dictada por el autor, en la que esboza una experiencia de desarrollo institucional de la Universidad de los Andes, a partir de la creación de un Seminario cuya mirada ofrece variados significados y…

In this study we analyze the meaning of symbols based on the psychological approach of Piaget. In addition, we would like to stimulate more research in this area. A symbol has sense when it has a nexus with a specific…

Human health risk assessment and management (HHRAM) is a systemic approach to characterize the nature and concentration of human health risks associated with any health hazard and the possible restoration of health by utilizing the scientific and technological knowledge. Computer…

The jurist Balsamon, in the course of his legal strictures on women who are mentruating, exhibits some detailed knowledge of anatomical and erotic literature and of unorthodox sexual practices.

Homer's several statements about the polar constellations prompted ancient critics both to emend the received text, in order to attribute to Homer advanced astronomical knowledge, and to defend it, by means of reinterpretation.
