In this paper we present a new model of Web traffic and its applications in the performance evaluation of Web servers. We consider typical user hypertext navigation behavior within a Web server. We propose a traffic model at the session level, formulated as a stochastic marked point process, which describes when users arrive and how they browse the server.(More)
In this paper we introduce VS-SC, an efficient variable step size normalized LMS algorithm for updating the coefficients of a FIR structure in noise and echo canceling applications. In the VS-SC algorithm the step size adjustment is controlled by the square of the correlation between the output error and the adaptive filter output. The proposed algorithm is(More)
