This work analyses a multiprocessor system in which processes communicate with each other via buffers using SEND and WAIT operations. Since the buffers are of finite capacity, a process which cannot execute a synchronisation operation successfully must leave the processor and go into the blocking state. The analysis of the multiprocessor system is executed hierarchically using two models (Globa...

To myself and my parents... iii ACKNOWLEDGEMENTS Throughout my graduate studies, I am indebted to many people for their help and encouragement. First of all, I would like to thank my advisor Prof. Hayriye Ayhan. It is impossible for me to express in words my full appreciation. However, I would like to thank all of her advice and support during my graduate studies. I would not have completed thi...

Ultra-reliable communication (URC) is a key enabler for supporting immersive and mission-critical 5G applications. Meeting the strict reliability requirements of these applications challenging due to absence accurate statistical models tailored URC systems. In this letter, wireless connectivity over dynamic channels characterized via learning methods. particular, <italic xmlns:mml="http://www.w...

In cellular networks, blocking occurs when a base station has no free channel to allocate to a mobile user. One distinguishes between two kinds of blocking, the first is called new call blocking and refers to blocking of new calls, the second is called handoff blocking and refers to blocking of ongoing calls due to the mobility of the users. In this paper, we first provide explicit analytic exp...

In this study, the results of parallelization of a 3-D dual code (Thin Layer, Parabolized Navier-Stokes solver) for solving supersonic turbulent flow around body and wing-body combinations are presented. As a serial code, TLNS solver is very time consuming and takes a large part of memory due to the iterative and lengthy computations. Also for complicated geometries, an exceeding number of grid...
