A regeneration-theory approach is undertaken to analytically characterize the average overall completion time in a distributed system. The approach considers the heterogeneity in the processing ratesâ€¦ (More)

The frequency-response characteristics of avalanche photodiodes (APDs) with thin multiplication layers are investigated by means of a recurrence technique that incorporates the history dependence ofâ€¦ (More)

It has been recently found that the initial-energy effect, which is associated with the finite initial energy of carriers entering the multiplication region of an avalanche photodiode (APD), can beâ€¦ (More)

Bit-error rates are computed for an on-off keying optical communication system using avalanche photodiodes (APDâ€™s). We use a model for the APD that includes dead space and the finite response time.â€¦ (More)
