Design of structured vector quantizers for diversity communication systems
(Texas A&M University, 1994)
In this study we develop techniques for transmitting information over multiple channels. Improvements are made over available systems which use scalar quantization. The main contribution is in the application of a fixed ...
A neural network approach to the automated detection of acoustic annoyance in hard disk drives
(Texas A&M University, 1994)
In order to increase efficiency, computing equipment in the office environment is increasing rapidly. However, the increase in efficiency is not optimized since the added equipment also brings added noise to the environment. ...
Speed limitations of optical switching using a piezoelectric transducer
(Texas A&M University, 1994)
Optical switching in interferometers using piezoelectric elements is investigated. Complete switching requires that the piezoelectric element induce enough mechanical motion to produce a 7r-radian phase shift in one arm ...
Measurement of laser frequency response through heterodyne technique using optical modulation
(Texas A&M University, 1994)
An optical modulation technique for measuring the parasitic-free frequency response of high frequency semiconductor lasers is demonstrated. In this technique, we heterodyne light from two continuously tunable external ...
Design and evaluation of a wide bandwidth logarithmic-ratio beam position monitor processor for the Proton Storage Ring at the Los Alamos Meson Physics Facility
(Texas A&M University, 1994)
The Proton Storage Ring (PSR) is a facility used for high intensity neutron studies at the Los Alamos Meson Physics Facility(LAWF), located at the Los Alamos National Laboratories, Los Alamos, New Mexico. A wide bandwidth ...
Fiberoptic Fabry-Perot engine pressure sensor system using a continuous wave laser source
(Texas A&M University, 1994)
A fiber optic Fabry-Perot engine pressure sensor using a continuous wave laser source is implemented and tested. The operating point of the Fabrv-Perot sensor is locked to the quadrature point by electronic feedback control ...
A hierarchical structure of neural network implemented for the recognition of automobile license plate number
(Texas A&M University, 1994)

Unequal error protection of subband coded bits
(Texas A&M University, 1994)
Source coded data can be separated into different classes based on their susceptibility to channel errors. Errors in the Important bits cause greater distortion in the reconstructed signal. This thesis presents an Unequal ...
Design and simulation of an FPGA architecture
(Texas A&M University, 1994)
This thesis investigates the design and simulation problems of application specific Field Programmable Cate Array (FPGA) architectures. As a revolutionary idea in semicustom integrated circuits, FPGAs can provide very low ...
An economical single to three phase converter for induction motors
(Texas A&M University, 1994)
There are several different types of single to three phase converters for induction motors available today. However, many of the presently available phase converters suffer from disadvantages such as high cost or low ...
