Ambiguous Energy Suppression in Encryption Derived Pseudo-Random BPSK Radar Signals
(2021-12-01)
In this thesis, a pseudo-random binary phase shift keying (BPSK) radar signal is developed using Advanced Encryption Standard (AES-192). The primary objective of this encryption based BPSK (E-BPSK) signal is to provide a ...
Analysis and Correction of Three-Dimensional Proximity Effect in Binary E-Beam Nano-Lithography
(2007-05-15)
One of the fundamental problems in transferring a circuit pattern onto a substrate using electron beam lithography is the proximity effect, which is due to electron scattering in the resist
and results in the ``non-ideal"" ...
Analysis of DC Power Systems Containing Induction Motor-Drive Loads
(2006-05-15)
The development of an analytical method used for conducting a power flow analysis on a DC power system containing multiple motor-drive loads is presented. The method is fast, simplistic, easy to implement, and produces ...
Analysis of Flywheel Energy Storage Systems for Frequency Support
(2021-03-02)
Flywheels have been used to store energy in rotation for centuries. However, they were previously not suited for storing electrical energy because of their lower operating speed. However, with AC to DC converters, the ...
Analysis of Simulated Performance of Integrated Vector Tracking and Navigation Loops for GPS
(2005-12-15)
An alternative GPS signal tracking method that uses an extended Kalman-Bucy filter in place of traditional independent, parallel tracking loops is presented in this thesis. Furthermore, this method is extended into a ...
