This paper describes the application of static var compensators, (SVC) on an electrical distribution network containing two large synchronous motors, one of which is excited via a three-phase thyristor bridge rectifier. The second machine is excited via a diode bridge rectifier. Based on linear optimization control (LOC), the measurable feedback signals are applied to the control system loops o...

This chapter explores how, in a single decade (1995-2005), research into computer-mediated communication (CMC) has evolved by examining the Journal of Computer-Mediated Communication (JCMC). JCMC is a peer-reviewed, interdisciplinary, open-access electronic journal that publishes primarily empirical research and presents a significant body of work falling under the rubric of CMC. JCMC has publi...

This collection of articles was originally inspired by several presentations at CATaC’04 and subsequent critical discussion of their use of the frameworks for cultural analyses developed by Edward T. Hall (1966, 1976) and Gert Hofstede (e.g., 1980, 1991). In response to these presentations and discussion, we developed this special thematic section for the Journal of Computer-Mediated Communicat...

In this paper, based on feedback linearization control method and using a special PI (propotational integrator) regulator (IP) in combination with a feed-forward controller, a three-phase induction servo-drive is speed controlled. First, an observer is employed to estimate the rotor d and q axis flux components. Then, two input-output state variables are introduced to control the dynamics of to...
