Most systems which require phase information use mixers somewhere in the measurement or comparison of the phase information. Theoretically, any mixer with a dc coupled port could be used as a phase detector. Practically, however, mixers often display some very non-ideal characteristics (e.g., dc offset) when used as phase detectors. The actual mixer chosen for a particular application will ofte...

With the emergence of technologies designed to support social activities online, it is beneficial to explore their potential in novel application areas. These studies, in the research tradition of Bowers et al. (1996), can be used to evaluate and develop technologies while providing the opportunity to study the social practices that develop around their use. We examine the use of online seminar...

Virtual synchrony is an important abstraction that is proven to be extremely useful when implemented over asynchronous, typically large, message-passing distributed systems. Fault tolerant design is a key criterion for the success of such implementations. This is because large distributed systems can be highly available as long as they do not depend on the full operational status of every syste...

A self-stabilizing simulation of a single-writer multi-reader atomic register is presented. The simulation works in asynchronous message-passing systems, and allows processes to crash, as long as at least a majority of them remain working. A key element in the simulation is a new combinatorial construction of a bounded labeling scheme that can accommodate arbitrary labels, i.e., including those...
