Gossiping is an extensively investigated information dissemination process. In gossiping, every vertex holds a message which has to be transmitted to all other vertices. This paper deals with k-failure tolerant gossiping, which investigates the minimum number of transmissions (calls) required by the communication process, provided that at most k transmissions may fail. We show new bounds for th...

Two properties of optical transmissions, namely, unidirectional propagation and predictable propagation delay, make it possible to pipeline packet transmissions in alloptical networks. In this paper, we study the problem of scheduling All-to-All Personalized Communication (AAPC) in unidirectional TDM/WDM rings with pipelined transmissions, which can achieve a much higher bandwidth utilization t...

The University of Denver's remote sensor (FEAT) was used for an on-road motor vehicle carbon monoxide (CO) and hydrocarbon (HC) emissions survey in Australia during April and May, 1992. Twelve locations in Melbourne area were selected as the survey sites. Most of these locations were the on or off ramp of a freeway or a two way road divided by a solid or painted traffic island. The raw data fro...
