Operational extensions to a power distribution design workstation for enhanced emergency restoration
(Virginia Tech, 1990-12-05)
<p>A power distribution design engineering workstation is used as the basis for a restoration management system. The complete system contains three separate programs. The three programs are the Telephone Operator program, ...
Investigation of transport mechanisms for n-p-n InP/InGaAs/InP double heterojunction bipolar transistors
(Virginia Tech, 1989-01-05)
<p>A more complete model for InP/InGaAs Double Heterojunction Bipolar Transistors (DHBT) is obtained in this thesis by physically analyzing the transport process of the main current components. The potential distribution ...
Performance characteristics of a multiple use Ku-band satellite network
(Virginia Tech, 1989-05-05)
Construction of a Ku-band earth station was completed in August 1989 at the teleport in the Corporate Research Center of Virginia Polytechnic Institute and State University. At that time specific applications for the ...
Insulated gate transistors: characteristics and application to motor control
(Virginia Polytechnic Institute and State University, 1984)
Analysis and design of a low-ripple coupled-inductor boost topology
(Virginia Tech, 1993-06-05)
This thesis presents the development, analysis, and design of a new low-ripple coupled-inductor boost topology. This topology is proposed for applications in which the conventional boost requires an input filter and two-stage ...
Degradation in lead zirconate titanate thin film capacitors for non-volatile memory applications
(Virginia Tech, 1994-07-05)
A study of the degradation of ferroelectric properties in Lead Zirconate Titanate (PZT) thin film capacitors is presented in this work. Metal- Ferroelectric - Metal capacitors were prepared by sputtering and metal organic ...
Performance analysis of CDMA systems in multipath channels
(Virginia Tech, 1993-04-23)
This thesis provides a performance analysis of Code Division Multiple Access (COMA) systems in non-ideal conditions. Two benefits of CDMA include resistance to multipath fading and graceful performance degradation in the ...
Behavioral testbench development for DSP models
(Virginia Tech, 1995-02-05)
<p>Generation of testbenches for large DSP behavioral models is a complicated, labor intensive task. Also, tests generated manually satisfy no formal definition of completeness. To address these needs, high level approaches ...
A microprocessor control scheme for switched reluctance motor drives
(Virginia Polytechnic Institute and State University, 1987)
