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 ...
On an Elementary Characterization of the Increasing Covex Ordering, with an Application
(1993)
In this short note, we present a simple characterization of the increasing convex ordering icx on the set of probability distributions on IR. We show its usefulness by providing a very short proof of a comparison result ...
Efficient Simulation of DEDS by Means of Standard Clock Techniques: Queueing and Integrated Radio Network Examples
(1993)
Simulation is an important tool in the study of communication networks manufacturing systems, and other complicated man-made systems. Many systems of this type are examples of discrete- event dynamic systems (DEDS) for ...
Threshold Reliability of Networks with Small Failure Sets
(1993)
This paper addresses two classes of reliability analysis models: a network flow model and a project scheduling model. For the network flow model we are given a capacitated source/sink graph in which arcs fail randomly. The ...
Reliability, Covering and Balanced Matrices
(1993)
The paper addresses a certain generalized covering integer program. The original application that motivated the study of this problem was an emergency services vehicle location problem. In this paper, we show that the same ...
A Study of the Reflection Symmetric Residual Quantizer and Application to Speech Coding
(1993)
The performance of the reflection symmetric residual quantizer (rRQ) on various types of sources is tested and certain conclusions about its capabilities and limitations are drawn. rRQ is then used to design several ...
Entropy-Constrained Trellis Coded Quantization: Implementation and Adaptation
(1993)
Entropy-constrained trellis coded quantization (ECTCQ) of memoryless sources is known to be an efficient source coding technique in the rate-distortion sense. We develop an ECTCQ scheme that employs a symmetric reproduction ...
Representation of Spectral Profiles in the Auditory System Part II: A Ripple Analysis Model
(1993)
Based on experimental results presented in [Vranic-Sowers and Shamma, 1993], and on further physiological and psychoacoustical evidence, it is argued that the auditory system analyzes a spectral profile along two largely ...
Temporally Dynamic Neural Networks for Speaker Independent Phoneme Recognition
(1993)
An alternative view of neural network based phoneme recognition based on multiresolution signal processing which incorporates noncausal context is suggested. Also some suggestions are made regarding target and error weight ...
