We consider a polling system which consists of a number of queues attended by a single server. The server switches from one queue to another following a fixed cyclic order. Such a system finds a wide variety of applications ...

The aim of this dissertation is to develop approximations to performance measures for queues with synchronization constraints with the help of limit theorems. In particular we shall consider queues exhibiting the fork-join ...

The well-known error propagation problem inherent in any variable-length coding operation limits the usefulness of variable-length encoded entropy-constrained scalar quantizers when the quantizer outputs are to be transmitted ...

This paper considers the reliability of systems that employ fault tolerance at two different hierarchical levels. Specifically, it assumes the system consists of a two-dimensional array of components. Each component is ...

Consider an additive noise channel with inputs and outputs in the field GF (q ) where q > 2; every time a symbol is transmitted over such a channel, there are q - 1 different errors that can occur, corresponding to the q ...

A functional model of the primary auditory cortex is proposed based on physiological maps of the receptive field organization in ferret AI (Shamma, Fleshman and Wiser [1990]). Systematic changes in the excitatory and ...

A vacation model is a single-server queueing system where the server occasionally takes a vacation, i.e., becomes unavailable to the customers for a period of time. Under a limited service policy with parameter m, m = ...

We consider the problem of designing a bandwidth-efficient, power-limited digital communication system for transmitting information from a source with known statistics over a noisy waveform channel. Each output vector of ...

In this note, we derive various convexity and monotonicity properties of performance measures in parallel GI/GI/1 queues with Bernoulli routing. We then use these results to establish that the equilikely assignment is ...

We investigated the effects of feedback on a decentralized detection system consisting of N sensors and a data fusion center. It is assumed that observations are independent and identically distributed across sensors, and ...
