A statistical multiplexer with a finite number of independent, not necessarily identical, bursty traffic sources is considered in this paper. Each source stochastically alternates between on-periods, during which it generates one cell per slot, and off-periods, during which no cells are generated. The on-periods and the off-periods are assumed to be independent, but are allowed to have general ...

This article presents a tri-band shared-aperture full-corporate-feed continuous transverse stub (CTS) antenna based on hollow-waveguide. The multiband operation is enabled by broadband CTS radiator and novel six-port parallel-plate waveguide (PPW) multiplexer. radiation slot fed vertical PPW power divider. multiplexer composed of three diplexers, which defines the frequency bands—Ku, K, Ka. qua...

In this paper the delay jitter affecting a monomedia traffic stream, when N multimedia streams are mixed in an ATM multiplexer, is evaluated. To this purpose a multimedia source is modeled as an arrival process defined as the superposition of heterogeneous correlated arrival processes, each of which models one monomedia source by means of an ON-OFF process whose transition rates are functions o...

This paper discusses design and testing of a Moving Picture Experts Group 2 (MPEG-2) Transport Stream (TS) multiplexer in Field Programmable Gate Array (FPGA) technology that would transmit multiplexed packets via Ethernet. Multiplexer is designed in accordance with standard ISO/ IEC 13818-1, thus it is fully compatible with standard players. The digital design is very flexible since adding add...

____________________________________________________________________________ Abstract The present ISR describes the encircled energy(EE) analysis of pinhole images made on the M10 WFC3 1R-MUX at the Goddard Space Flight Center (GSFC) Detector Characterization Lab (DCL) on 29 May 2001. Analysis shows that the pinhole image’s centroid is stable within a 1-pixel area and the 80% of the encircled e...

Wilson's XCS has rapidly become the most popular classier system of all time, and is a major focus of current research. XCS's primary distinguishing feature is that it bases rule tness on the accuracy with which rules predict reward, rather than the magnitude of the reward predicted (as traditional, strength-based systems do). XCS is a complex system and di ers from other systems in a number of...

The delay analysis of a statistical multiplexer with heterogeneous input sources is presented in this work. The traac generated by an individual source is described in terms of a discrete-time Batch Markovian arrival process with geometrically distributed idle periods. An exact closed form expression for the mean packet delay in the system is obtained by exploiting the stochastic structure of t...
