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…

Objective – To investigate whether African American students’ computer attitudes predict levels of library anxiety.

Design – A user study in which two instruments were administered to a group of graduate students to measure computer attitudes and library anxiety.

In this paper we state how Cognitive Maps can be used to model causal phenomena. In addition, we show the application of the Cognitive Maps to the field of the Student Modeling. Conceptually speaking, Cognitive Maps set and simulate the…

This paper gives a brief account of the current state of knowledge about Chinese wares discovered during the course of recent excavations in the Angkor Archaeological Park. It goes on to suggest that the ceramic sequence established by Bernard-Philippe Groslier…

It is with great pleasure that the Research in the Workplace Award (RIWA)* assessment panel announces the winning proposal in 2006/2007 to be for a multi-site randomised controlled trial to determine the impact of providing a virtual reference service (Access…

Abstract: This paper examines three major paradigms—mass communications, political economy, and poststructuralism—to demonstrate how the process of knowledge production erases their connection with their postcolonial subjects and locations. This mapping indicates that what one perceives to be at the margins…
