Optimal Linear Coding For A Multichannel System, Kyong-Hwa Lee

Electrical and Computer Engineering ETDs

This paper is concerned with the problem of obtaining the optimal linear vector coding (transformation) method that matches an r-dimensional vector signal and a k-dimensional channel under a given channel power constraint. the encoder converts the r correlated random variables into r independent random variables and selects at most k independent random variables which correspond to the k largest eigenvalues of the signal covarience matrix Q. The encoder reinserts cross-correlation into the k random variables in such a way that the largest eigenvalue of Q is assigned to the smallest eigenvalue of the channel noise covarience matrix R and the …

Axial Xenon Redistribution And Power Shaping In Large Pressurized Water Reactors, Henrique F. V. A. Machado Jorge

Nuclear Engineering ETDs

The reactor described herein is aimed at developing an accurate physical model for axial power shaping studies in pressurized water reactors of the current generation. The model is also intended for numerical studies on: (1) reactor load-follow capability throughout a fuel loading lifetime; and (2) burnup dependence of the reactor stability against axial xenon oscillations. Accordingly, a proper account of the concerned physical phenomenology was sought. The results reported herein solely concern methods development and assessment.

A one-dimensional (axial) core geometrical model, coupled with

fuel temperature-and moderator coolant thermal-hydraulics-feedback was assembled. Algorithms for computing the feedback effects were developed and …

Evaluation Of Paint-Stripe Beads, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objectives of this phase of the overall "Roadway Delineation" study were to evaluate the luminosity and durability of several types of glass beads and one type of plastic bead used with paint stripes and to determine their effectiveness during rainy, nighttime conditions. Eleven types of beads were evaluated. They were applied at rates approximating 4, 5, and 6 pounds per gallon (479, 599, and 719 kg/m3). Photometer and visual observations extended to about 9 months after application of test stripes.

Design Of Film-Substrate Single-Reflection Linear Partial Polarizers, R. M.A. Azzam, A.-R. M. Zaghloul, N. M. Bashara

Electrical Engineering Faculty Publications

The results of a preceding paper [J. Opt. Soc. Am. 65, 1464,(1975)] are viewed from a different angleas providing the basis for the design of film-substrate single-reflection linear partial polarizers (LPP),which also operate as reflection optical rotators. The important characteristics of a comprehensive set of discrete designs of SiO₂-Si LPP’s at λ = 6328 Å are shown graphically.

Polarizer-Surface-Analyzer Null Ellipsometry For Film-Substrate Systems, R. M.A. Azzam, A.-R. M. Zaghloul, N. M. Bashara

Electrical Engineering Faculty Publications

Single-pass polarizer-surface-analyzer null ellipsometry (PSA-NE) can be used to characterize film-substrate systems, provided that the film thickness lies within one of a set of permissible-thickness bands (PTB). For a transparent film on a transparent or absorbing substrate, the PTB structure consists of a small number of finite-bandwidth bands followed by a continuum band that extends from a film thickness of about half the wavelength of light to infinity. We show that this band structure is a direct consequence of the periodicity of the ellipsometric function ρ (the ratio R_p/R_s, of the complex amplitude-reflection coefficients for …

Anion Grain-Boundary Diffusion In Soidum Chloride, K. S. Sabharwal, J. Mimkes, Manfred Wuttig

Materials Science and Engineering Faculty Research & Creative Works

The grain-boundary diffusion of 131I in Harshaw pure and Ca-doped NaCl was investigated in the temperature range between 430 and 560°C. The Arrhenius plot of the grain-boundary diffusivity parameter Dδ displays a marked dip at around 510°C. It is proposed that this dip is due to a phase transformation occurring at the grain boundary, possibly calcium segregation.

Threshold Characteristics Of Multimode Laser Oscillators, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

The oscillation characteristics of a multimode laser are considered in detail, and for the first time saturation by all of the cavity modes is included. Analytical expressions are obtained for the mode amplitudes, linewidths, and over‐all spectral characteristics of lasers operating above and below threshold. It is found that with increasing excitation the spontaneous emission spectrum is gradually resolved into a set of narrow discrete modes. Slightly above threshold the number of modes reduces in a homogeneoulsy broadened laser until only a single mode is oscillating strongly. The theoretical results are in agreement with experimental data that have been reported …

Optimal And Suboptimal Estimation In Differential Pcm And Adaptive Predictive Coding Systems, Jerry Gibson

Department of Electrical and Computer Engineering: Faculty Publications

Both differential pulse code modulation (DPCM) and adaptive predictive coding (APC) systems have been used somewhat successfully for low date rate digital voice transmission. A DPCM system has as its goal the removal of signal redundancy prior to transmission by a linear prediction of the incoming signal with a weighted combination of past signal estimates. The error in the prediction process is then quantized and transmitted to the receiver. An identical prediction loop is used at the receiver to reinsert the redundancy, and hence, to reconstruct the speech signal. Both the quantizer and predictor may or may not be adaptive.
