#### Nonexhaustive Policies in Polling Systems and Vacation Models: Qualitative and Approximate Approach

(1990)

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 ...

#### Computation of the Circular Error Probability Integral

(1991)

This note describes a simplified derivation of the representation of the circular error probability (CEP) integral, which is the integral over a disk centered at the origin of a zero mean two dimensional Gaussian random ...

#### Modeling Perception of Spectral Profile Changes

(1993)

In this thesis, we explore how the human auditory system represents and detects changes in a spectral profile. First, using profile analysis methods, we measure listeners' sensitivities to changes in spectral peak shapes ...

#### Signal Detection Games with Power Constraints

(1993)

In this paper we formulate mathematically and solve maximin and minimax detection problems for signals with power constraints. These problems arise whenever it is necessary to distinguish between a genuine signal and a ...

#### Deterministic Codes for Arbitrarily Varying Multiple-Access Channels

(1988)

The Arbitrarily Varying Multiple-Access Channel (AVMAC) is a model of a multiple-access channel with unknown parameters. In 1981, Jahn characterized the capacity region of the AVMAC, assuming that the region had a nonempty ...

#### Representation of Spectral Profiles in the Auditory System, II: Detection of Spectral Peak Shape Changes

(1994)

Based on the ripple analysis model outlined in Part I of this paper, predictions are made for the detection of shape changes in spectral peak profiles. Peak shape is uniquely described in terms of two parameters: bandwidth ...

#### Minimum Mean Square Error Estimation of Connectivity in Biological Neural Networks

(1991)

A minimum mean square error (MMSE) estimation scheme is employed to identify the synaptic connectivity in neural networks. This new approach can substantially reduce the amount of data and the computational cost involved ...

#### On the Effects of the Initial Condition in State Estimation for Discrete-Time Linear Systems

(1992)

We consider the one-step prediction problem for discrete-time linear systems in correlated Gaussian white plant and observation noises, and non-Gaussian initial conditions. Explicit representations are obtained for the ...

#### Critical Points of Matrix Least Square Distance Functions

(1992)

A Classical problem in matrix analysis and total least squares estimation is that of finding a best approximant of a given matrix by lower rank ones. In this paper the critical points and the local minima are determined ...

#### A Three-Component Image Model Based on Human Visual Perception and Its Applications in Image Coding and Processing

(1992)

In this work, results of psychovisual studies of the human visual system are discussed and interpreted in a mathematical framework. the formation of the perception is described by appropriate minimization problems and the ...
