Multi-agent systems (MAS) offer an approach to solve complex problems where data and control are inherently distributed among several agents. Normally, agents have to cope with conflicts based on inconsistent knowledge which arise when they exchange information. A relative common…

To understand speech in noisy situations, listeners must not only `extract' the speech signal from the background noise, but also determine the meaning of the words and phrases in the extracted signal, integrate this information with past knowledge, and store…

Geoacoustic properties of the upper tens of metres of ocean bottom sediments can significantly influence low-frequency acoustic propagation in the ocean. Therefore, knowledge of these properties is required for reliable propagation modelling and matched-field processing. To date, however, few measurements…

Each year, complaints are filed at the Quebec and Canadian Human Rights Commission by individuals who have been refused employment because their hearing sensitivity does not meet the standards required by the employer. This paper presents four recent cases. The…

The CHHA survey about hard of hearing youth found that access is a major difficulty. In asking young hard of hearing persons about their experiences in everyday life, the survey found that about half had difficulty, watching television, over half…

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…
