Studies of Structural, Nonlinear Optical and Thermal Properties of Specific Nonconjugated Conductive Polymers Including a Co-Polymer Styrene-Butadiene-Rubber
(2012-05-10)
The structures, quadratic electro-optic effects, thermal properties, and photovoltaic characteristics of specific nonconjugated polymers have been studied. Various tools and techniques such as Optical absorption, Differential ...
Prognostic Health Management for Mission and Safety Critical Electronics
(2012-07-17)
The increasing reliance on electrical systems to fulfill mission and safety critical applications has motivated the need for in situ monitoring of functioning electrical systems and a priori warnings of failure. In this ...
Development and Application of Composite Material Lamination Theory for Printed Circuit Boards
(2012-08-03)
Layers incorporating carbon fiber materials have been proposed to enhance the reliability of high performance printed circuit board production configurations. The carbon fiber layers feature high stiffness and high thermal ...
Energy Cost Reduction for Medical Facilities
(2012-11-07)
An intensive energy audit was performed on Russell Medical Center located in Alexander City, AL. It began in 2009 and was completed in 2012. The purpose of this audit is to find effective strategies to reduce energy costs ...
Fault Detection and Exclusion in Deeply Integrated GPS/INS Navigation
(2012-12-04)
This dissertation presents a novel fault detection and exclusion method in a centralized deeply integrated GPS/INS navigation system.
The method presented is also demonstrated in a centralized vector tracking GPS ...
Experimentation and Modeling of NOx Formation in a Small Turbo-Charged Diesel Engine
(2012-12-05)
In this thesis a detailed investigation into the primary formation characteristics and modeling approaches for the formation of NOx in turbo-charged diesel engines is presented. Through this investigation a multi-layered ...
Reduction of Lead Free Solder Aging Effects Using Doped SAC Alloys
(2012-10-08)
The microstructure, mechanical response, and failure behavior of lead free solder joints in electronic assemblies are constantly evolving when exposed to isothermal aging and/or thermal cycling environments. Large ...
Tire Force Estimation in Off-Road Vehicles Using Suspension Strain and Deflection Measurements
(2012-01-24)
This thesis develops and analyzes the improvement of tire force estimation and analysis using strain gauge sensors and displacement sensors mounted on the suspension of an all-terrain vehicle. Vehicle dynamic models are ...
Sound Attenuation Using MEMS Fabricated Acoustic Metamaterials
(2012-04-11)
Unlike traditional rotational gyroscopes, MEMS gyroscopes use a vibrating proof mass rather than a rotational mass to sense changes in angular rate. They are also smaller and less expensive than traditional gyroscopes. ...
