L’objectif de ce mémoire est de faire un état des lieux des connaissances produites sur les risques environnementaux et la vulnérabilité et appliquer ces connaissances à la ville de Kigali (Rwanda). Après avoir présenté différentes approches, nous avons retenu le…

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,…

Emerging international research suggests that
enhancing teacher-student assessment for learning
(AfL) interactions is a key to enhancing student
learning. Planning frameworks that make explicit the
multiple dimensions of technology can be used to
extend teacher knowledge and focus interaction.
Effective…

Žinių samprata yra sudėtinga, įvairi ir daugiaprasmė. Moksliniu požiūriu žinių prigimtį ir esmę jau keletą dešimtmečių tyrinėja įvairių sričių mokslininkai, tačiau iki šiol nėra sukurtos visuotinai pripažintos žinių potencialo vertinimo metodikos, vartojamos skirtingos sąvokos, nesutariama, kokie veiksniai yra esminiai vertinant…

Over the past decade, several prominent U.S.
organizations have suggested Americans – particularly
American students – should be more knowledgeable
about technology to be successful, well-rounded
citizens. However, these urgings have been made
largely in the absence of data about…

In questo articolo viene descritto un componente del sistema Anagrafe Nazionale delle Ricerche che consente l’integrazione dei dati dei brevetti EPO esportati dal software MIMOSA dell’European Patent Office (EPO). Il componente permette una migliore conoscenza dei soggetti iscritti all’anagrafe sotto…

This paper will address five questions that emerge
from the title of the Design and Technology
Association Education and International Research
Conference 2007: ‘Linking Learning’: (a) How can we
think about learning so that it informs our work in
design…
