Waiting times for M / M systems under generalized processor sharing

We consider a system where the arrivals form a Poisson process and the required service times of the requests are exponentially distributed. According to the generalized processor sharing discipline, each request in the system receives a fraction of the capacity of one processor which depends on the actual number of requests in the system. We derive systems of ordinary differential equations fo...

M/G/∞ with exponentially distributed setup times

We consider an M/G/∞ model with exponentially distributed setup times. Arrivals result in an off server starting a setup. Upon completing a setup, a server begins serving a waiting customer. Upon completing service, with probability p the server becomes eligible to serve another waiting customer. Among other things, we show, in steady state, that the number of busy servers is Poisson distribute...

M-theory observables for cosmological space-times

We discuss the construction of the analog of an S-matrix for space-times that begin with a Big-Bang and asymptote to an FRW universe with nonnegative cosmological constant. When the cosmological constant is positive there are many such S-matrices, related mathematically by gauge transformations and physically by an analog of the principle of black hole complementarity. In the limit of vanishing...

The Response Times of Priority Classes under Preemptive Resume in M/M/m Queues

a critical discourse analysis of the new york times and the tehran times news articles, covering the u.s.-led war in afghanistan

تحقیق حاضر متون خبری روزنامه های نیویورک تایمز و تهران تایمز را به صورت تحلیل انتقادی کلامی مورد بررسی قرارمی دهدکه درمورد جنگ به رهبری آ مریکا در افغانستان است. هدف از این تحقیق نشان دادن تاثیر ایدیولوژی و نگرشهای نویسندگان متون خبری است که ممکن است پنهان باشد. برای انجام این تحقیق 20 متن خبری) از هر روزنامه 10 متن خبری) به صورت تصادفی از سایت اینترنتی روزنامه های نیویورک تایمز و تهران تایمز ا...
