Spectral analyses of the dual polarization Doppler weather radar data.
(2007)
Echoes in clear air from biological scatterers mixed within the resolution volumes over a large region are presented. These echoes were observed with the polarimetric prototype of the forthcoming WSR-88D weather radar. The ...
III-V and Thin Film Photovoltaics for Extraterrestrial Application
(2019)
Photovoltaic power is one of the few options available for electrical devices stationed outside of our atmosphere. As the satellite market turns to smaller satellites based on the CubeSat and SmallSat form factor, these ...
Generation asset planning under uncertainty.
(2005)
With the introduction of competition in the electric power industry, generation asset planning must change. In this changed environment, energy companies must be able to capture the extrinsic value of their asset operations ...
Electromechanical Systems
(2018-12-19)
This eBook was written as the third installment in the series that coincide with three engineering courses taught at the University of Oklahoma (ENGR 2431, ENGR 2531, and ENGR 3431). These courses were designed to provide ...
Adaptive Localized Active Route Maintenance Mechanism to Improve Performance of VoIP over Ad Hoc Networks
(2011-02)
An important characteristic of a mobile ad hoc network routing protocol is connectivity maintenance. The protocol’s ability to maintain routes and react to topology changes due to link failures affects the delay, packet ...
Analysis of Backbone Technique: a Hilbert Transform and Discrete Hilbert Transform-based Technique
(2015-12)
This dissertation focuses on understanding and improving the “backbone” technique, a Hilbert-transform based vibration signal processing technique developed by Dr. Michael Feldman started in 1994. The concept of backbone ...
LOW-COST, SOFTWARE DEFINED FMCW RADAR FOR OBSERVATIONS OF DRONES
(2017-05-12)
This thesis focuses on implementing a small, low-cost, Frequency-Modulated-Continuous-Wave (FMCW) radar sensor using Software-Defined Radio (SDR) platforms. Extensive investigation and comparisons of existing SDRs are ...
Adaptive Distributed Source Coding Based on Bayesian Inference
(2015-08-14)
Distributed Source Coding (DSC) is an important topic for both in information theory and communication. DSC utilizes the correlations among the sources to compress data, and it has the advantages of being simple and easy ...
Analog free-space optical links.
(2005)
Free-space optics (FSO) communications is a technology that uses modulated infrared optical beams to transmit information line-of-sight through the atmosphere. There has been a substantial increase in the use of FSO ...
Ruggedized Feeding Techniques for Placement Insensitive Antennas
(2018-08-02)
Today's warfighter relies on extensive wireless technology to stay connected to allied forces and the battle theater. Communication equipment, IFF (identification friend-or-foe) identifiers, global positioning systems, ...
