The paper studies the characteristics of synchronous ordering of messages. Synchronous ordering of messages defines synchronous communication based on the causality rather than time. We present the sufficient conditions, based on the causality relations, for any algorithm to provide synchronous ordering. We also propose an algorithm using acknowledgment messages to implement the sufficient conditions. The algorithm is deadlock-free, and provides a higher degree of concurrency than existing algorithms.< >

Krebs, S.Dr.-Ing. Stephan Krebs (1963) received his Diploma degree in 1960 and his Dr.-Ing. degree in 1994 from the Elektrotechnisches Institut
Universitat Karlsruhe/Germany. His main fields of interest are the use of modem time-discrete control methods and parallel signal processing in adjustable speed drive and power supply systems. In summer 1994 he joined the Power Group of the Department of Electrical and Computer Engineering of the University of Toronto/Canada where he is currently working on industrial controller platform for power applications.

The cascaded doublyfed machine consists of two separate induction machines which are interconnected by their rotor windings. This paper presents a general control structure for such machines, based on the principle of...
Adjustable speed drive systems using AC‐machines are often fed by voltage‐source inverters. This paper presents a new strategy to control the line‐side converter. State‐space and fuzzy methods are combined to achi...

This paper describes the implementation of transmission-line matrix (TLM) method algorithms on a massively parallelcomputer (DECmpp 12000), the technique of distributed computing in the UNIX environment, and the combination of TLM analysis with Prony's method as well as with autoregressive moving average (ARMA) digital signal processing for electromagnetic field modelling. By combining these advanced computation techniques, typical electromagnetic field modelling of microwave structures by TLM analysis can be accelerated by a few orders of magnitude.
