摘要:

In this paper, the congestion control in store and forward computer com-munication networks is studied, the method employed consists of a combination of a dynamic routing policy that minimizes the delay, and buffer nianagement schemes to control the flow of data. Simulation using liner programming has been carried out, under balanced and transient traffic conditions, on a simple 3–node network , the relative merits and drawbacks of each approach are discussed. Irland [2], showed that with static routing, the SQRT scheme improves the switch performance. In this paper it is shown that in the case of dynamic routing, the SQRT is an excellent solution to remedy the performance degradation caused by CP and CS schemes

摘要:

This article analyzes some stochastic processes that arise in a bulk single server queue with continuously operating server, state dependent compound Poisson input flow and general state dependent service process. The authors treat the queueing process as a semi–regenerative process and obtain the invariant probability measure and the transient distribution for the embedded Markov chain. The stationary probability measure for the queueing process with continuous time parameter is found by using semi-regenerative techniques. The authors also study the input and output processes and establish ergodic theorems for some functionals of these processes. The results are obtained in terms of the invariant probability measure for the embedded process and the stationary measure for the queueing process with continuous time parameter

摘要:

Bilinear stochastic evolution equations in Hilbert spaces with unbounded operators are studied by means of the semigroup approach. [BGeneral abstract results of regularity and well posedness are proved and applied to several more concrete problems, like classical variational equations, parabolic equations in non-variational form, non-homogeneous boundary value problems and feedback boundary control problems, and finally some equations which are not of parabolic type

摘要:

The paper deals with a generalization of the projection pursuit regression algorithm (see P.Huber [4]) in Hilbert space. Theorem 2.1 states the strong convergence of the generalized algorithm. This result then applied to certain spaces in order to define a new density estimator and to obtain results on density approximation and estimation

摘要:

Consider a set of independent Banach space-valued random elements indexed bythe positive integer d-dimensional lattice points, d ≥ 2. The classical Kolmogorov-Marcinkiewicz strong law of large numbers is obtained in this setting. In addition, a rate of convergence for the tall probabilities of the sample sums is determined

摘要:

This paper provides an optimal sequential decision procedure for deciding between two composite hypotheses about the unknown failure rate of an exponential distribution, using censored data. The procedure has two components, a stopping time and a decision function. The optimal stopping time minimizes the expected total loss due to a wrong decision plus cost of observing the process. The optimal decision function is easily characterized once a stopping time has been specified. The main result determines the continuation region for the optimal decision procedure
