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…

Seasonality is a characteristic and important feature of the birth rate, but hitherto largely undocumented for sub-Saharan Africa. The research we present in Chapter 2 helps close the gap by providing contemporary documentation of the seasonal patterns of births in…

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…

When there is a need to understand the data stored in a database, one of the main requirements is being able to extract knowledge in the form of rules. Classification strategies allow extracting rules almost naturally. In this paper, the…

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,…

La distinción clásica entre techne y praxis, destacada entre otros por Heidegger, Gadamer, Arendt, es central para comprender el estatuto del saber en la era técnica (moderna, posmoderna, hipermoderna, transmoderna) La tecnociencia ha ampliado el concepto de arte y esto…

La era clásica musulmana discurrió ardorosamente sobre la relación entre
conocimiento religioso y conocimiento racional, y el ser divino. Avicena (980-1037)
aportó argumentos que infl uyeron en el Islam, suscitando discusiones y rechazos,
principalmente de Al Ghazali (1058-1111), en su…

The analysis of high sports performance by means of technological advances has often been used to calculate the routes of sportsmen in the distances covered, or to calculate speed in orienteering. However, there is still little information on data for…
