Ad-hoc and Multi-hop Wireless Sensor Networks for Activity Capture in Cooperative Robotics 

Raghunathan, Arun (2006-12-15)
Cooperative robotics has been the focus of attention of various groups in recent years. The idea of using a team of robots instead of a single one to execute a task came from the necessity of accomplishing a task that is ...

Advanced Clustering Methods and Applications for Data Visualization 

Wu, Bo (2018-04-13)
Categorizing all sorts of data without any label information is one of the most important tasks in preprocessing raw data. To achieve that, an unsupervised learning technique, called clustering, is utilized. Generally, ...

Advances in Electronic Chaotic Oscillators with Applications in Communication Systems and Radar System 

Rhea, Benjamin (2019-07-18)
Chaos theory is an emerging topic in electronics due to some of the inherent properties that can be considered advantageous in particular applications. Some of these properties include topological mixing, continuous power ...

Alternative Techniques for Built-In Self-Test of Field Programmable Gate Arrays 

Newalkar, Aditya (2005-08-15)
In the Built-In Self-Test method of testing the logic and interconnect resources of the Field Programmable Gate Arrays (FPGAs), configuration time and time to retrieve of the test results dominate the duration of the test. ...

Ambiguous Energy Suppression in Encryption Derived Pseudo-Random BPSK Radar Signals 

Kamrath, Luke (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 

Anbumony, Kasi (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 

Leedy, Aleck (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 

Grider, Tanner (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 

Hamm, Christopher (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 ...
