This paper considers discrete-time single-server queueing systems where the arrivals of cells are a timecorrelated arrival process and the service for cells is done every R slots. In particular, the arrivals is governed by a stationary Markov chain, where no arrivals are assumed to occur only when the Markov chain is in a particular state. A typical example of the arrival processes satisfying t...

Abstract: We analyze a discrete-time single-server queueing system whose arrival stream is a Bernoulli process and service times are generally distributed. An extension of the N -policy is considered: the server remains idle till the queue length becomes 1 i ≥ with probability i θ . After the idle (vacation) period, the server needs a random amount of startup time before serving. Moreover, afte...

The scheduling needs of a large, diverse academic anesthesiology department are complex, and have a significant impact on surgical suite efficiency. Our departmnent needed a system that would reduce scheduling effort, decrease errors (particularly uncovered or understaffed assignments), and inprove schedule availability, the vacation request process and the ability to report on assignment histo...

The current study describes the assessment and treatment of the problem behavior of 3 individuals with autism for whom initial functional analysis results were inconclusive. Subsequent analyses revealed that the interruption of free-operant behavior using "do" requests (Study 1) as well as "do" and "don't" requests (Study 2) occasioned problem behavior. Initially, treatment involved differentia...

Most vacations seem to have strong, but rather short-lived effects on health and well-being (H&W). However, the recovery-potential of relatively long vacations and the underlying processes have been disregarded. Therefore, our study focused on vacations longer than 14 days and on the psychological processes associated with such a long respite from work. In the present study, we investigated (1)...
