In this paper we analyze a single server two queue model with Bernoulli schedules This discipline is very exible and contains the exhaustive and limited disciplines as special cases We formulate the queueing system as a Riemann boundary value problem with shift The boundary value problem is solved by exploring a Fredholm integral equation around the unit(More)
Despite of promising results in research, advanced control strategies fail to gain trust in wastewater treatment practice. Due to the sensitivity of the biological processes to disturbances, operators are often unable to find the causes of faults due to the lack of effective real-time on-line monitoring. Strategies for on-line monitoring are therefore(More)
In this paper we propose a new method of tra c smoothing for frames of di erent video sources We assume that each video source transmits frames at xed intervals and that the network is free to decide the relative temporal spacing of video frames from di erent sources This means that the time at which a given source begins to transmit its rst frame is under(More)
This paper considers overload control in telecommunication networks. Markov-modulated Bernoulli process ( MMBP ) has been extensively used to model bursty traffics with time-correlation. Thus, we investigate the transient behavior of the queueing system MMBP/D/1/K queue with two thresholds. The model is analyzed recursively by using the generating function(More)
