Ohmic contacts to p-type GaP
(Texas A&M University, 1996)
The objective of thisresearch was to develop ohmic contact schemes of low resistance, i.e. in the mid10-1 QCM2, to p-type Gallium Phosphide by the mechanism of solid-phase regrowth. The contact resistivityof the samples ...
Quantification of periventricular lesions from MR brain images
(Texas A&M University, 1996)
Periventricular lesions are associated with hyperintensity in Magnetic Resonance brain images of Acquired Immunodeficiency Syndrome patients. The objective of this research has been the development of a user-friendly ...
Performance evaluation of NUMA and COMA distributed shared-memory multiprocessors
(Texas A&M University, 1995)
Memory architecture is an important component in a distributed shared-memory parallel computer. This thesis studies three shared-memory architectures-Non-Uniform Memory Access (NUMA) with full-mapped directories, Cache-Only ...
Field emission study of cobalt ion implanted porous silicon
(Texas A&M University, 1995)
Porous silicon has become potentially important material for microelectronics applications. By using low energy implantation and energy scan implantation, a stable silicide with good electrical conductivity can be formed, ...
Design and analysis of instruction issue logic for hyperscaler processors
(Texas A&M University, 1995)
A dynamic instruction scheduling mechanism developed is presented. The proposed mechanism works out a compromise between the processor throughput and resource utilization. The scheduling mechanism issues instructions out ...
A field programmable analog array for switched capacitor filters
(Texas A&M University, 1994)
The advantage of using a semi-custom design approach over a fully custom design approach are a faster turnaround of circuit design, ease of use for the inexperienced engineer, and lower production costs. A semi-custom ...
W-CDMA performance evaluation of DS and MC - CDMA in the presence of multipath fading and partial-band interference
(Texas A&M University, 1998)
In this thesis, a performance evaluation of two third generation (3G) wide-band Code Division Multiple Access (W-CDMA) systems will be presented. The two systems considered are a single carrier direct sequence (DS) and a ...
Generation of high power, high repetition-rate pulses using erbium-doped fiber ring laser
(Texas A&M University, 1998)
This thesis presents the results obtained from crographics. generation of high repetition rate, high peak power output pulses using an erbium-doped fiber amplifier (EDFA). Two configurations were employed. The first setup ...
Compression and accelerated rendering of volume data using discrete wavelet transform
(Texas A&M University, 1998)
The medical community is increasingly using three-dimensional (3-D) visualization techniques to view data from CT scans, MRI etc. Two-dimensional (2-D) images cannot convey information on depth and location relative to the ...
Evolution of double-dwell serial search acquisition with automatic threshold control
(Texas A&M University, 1998)
An evolutionary double dwell serial search acquisition ics. with automatic threshold control for a code division multiple access (CDMA) direct sequence spread spectrum system is presented and analyzed. The acquisition ...
