On a synchronization queue with two finite buffers 总被引:1,自引:0,他引:1
In this paper, we consider a synchronization queue (or synchronization node) consisting of two buffers with finite capacities.
One stream of tokens arriving at the system forms a Poisson process and the other forms a PH-renewal process. The tokens are
held in the buffers until one is available from each flow, and then a group-token is instantaneously released as a synchronized
departure. We show that the output stream of a synchronization queue is a Markov renewal process, and that the time between
consecutive departures has a phase type distribution. Thus, we obtain the throughput of this synchronization queue and the
loss probabilities of each type of tokens. Moreover, we consider an extended synchronization model with two Poisson streams
where a departing group-token consists of several tokens in each buffer.
This revised version was published online in June 2006 with corrections to the Cover Date. 相似文献

The aim of this paper is the expansion of a matrix function in terms of a matrix-continued fraction as defined by Sorokin and Van Iseghem. The function under study is the Weyl function or resolvent function of an operator, given in the standard basis by a bi-infinite band matrix, with p subdiagonals and q superdiagonals, where the p + q – 1 intermediate diagonals are zero. The main goal of this paper is to find, for the moments, an explicit form in terms of the coefficients of the continued fraction, called genetic sums, which lead to a generalization of the notion of a Stieltjes continued fraction. These results are extension of some results already found for the vector case (p = 1) and are a step in the direction towards the solution of the direct and inverse spectral problem. The actual computation of the approximants of the given function as the convergents of the continued fraction is shown to be effective. Some possible extensions are considered. 相似文献

In this paper, we give necessary and sufficient conditions for infinite matrices mapping from the Nakano vector-valued sequence space (X, p) into any BK-space, and by using this result, we obtain the matrix characterizations from (X, p) into the sequence spaces (Y), c0(Y, q), c(Y), s(Y), Er(Y), and Fr(Y), where p = (pk) and q = (qk) are bounded sequences of positive real numbers such that pk 1 for all k N, r 0, and s 1.AMS Subject Classification (2000): 46A45 相似文献

This paper describes an efficient and numerically stable modification of the QR decomposition for solving a parametric set of linear least squares problems with a parametric matrix A + B for several values of the parameter . The method is demonstrated on a typical application. 相似文献

The definition for the convergence of a double sequence was presented by A. Pringsheim [9]. Recently, the definitions of limit inferior, limit superior, and the core of a double sequence are presented. By using these definitions and the notion of regularity for four-dimensional matrices, an invariant core theorem for double sequences is presented.AMS Subject Classification (2000) primary 40B05 secondary 40C05 相似文献
