Molecular Dynamics Simulations of Dry Sliding Asperities to Study Friction and Frictional Energy Dissipation
(2014-03-31)
Fundamental friction characteristics such as the friction coefficient, wear, adhesion, and dissipation of energy require an accurate understanding of how the surfaces in contact interact on nano or atomic scale. At nano ...
Detection and Removal of Erroneous GPS Signals Using Angle of Arrival
(2013-11-08)
In this thesis, an algorithm for detecting multipath and spoofed GPS signals based on signal angle of arrival (AOA) is developed. As the first step in determining the AOA of the signals, a multi-antenna array of GPS antennas ...
Cavitation Studies of Lumbar Zygapophysial Joints using Vibration Measurements
(2011-04-15)
The purpose of this research project was to locate the level of cavitation in zygapophysial (Z) joints in the lumbar spine (L1/L2-L5/S1) and the sacroiliac joints (SIJs) during side-posture positioning and spinal manipulative ...
Studies of Structures, Quadratic Electro-Optic Effect and Rechargeable Battery Characteristics in Specific Nonconjugated Conductive Polymers including Trans-1,4-Polyisoprene
(2011-05-05)
The structures, quadratic electro-optic effect and rechargeable battery characteristics in specific nonconjugated conductive polymers have been studied. FTIR spectroscopy, x-ray diffraction, optical absorption, differential ...
In-Cylinder Combustion Analysis of a Yamaha R6 FSAE Engine: Achieving Improved Engine Performance and Efficiency through Burn Rate Combustion Diagnostics
(2011-03-29)
The actual three-dimensional, turbulent combustion process that occurs in a modern,
spark-ignited internal combustion engine is very complex and difficult to model. However,
since cylinder pressure is directly related ...
Experimental Study of Renewable Energy Implementation in Cement Kilns through Industrial-Scale Downdraft Gasification of Poultry Litter
(2011-08-17)
Waste biomass, most notably poultry litter, is a potential source of energy that is widely available and cheap, especially in the southeast. Using poultry litter as an energy source provides a year-round outlet for this ...
An Experimental Investigation and a Multiscale Electro-thermo-mechanical Model of a Flat Pin High Power Electrical Connector
(2011-11-03)
Hybrid and electrical vehicles (HEV) are the next evolutionary step in automobile technology. However, the electrical systems which propel HEVs are fundamentally different from conventional technologies. Therefore, a few ...
Ues of Vision Sensors and Lane Maps to Aid GPS-INS Navigation
(2011-08-25)
This thesis proposes a method to increase observability of a GPS/INS system operating under limited satellite coverage. Measurements from vision sensors are used to supplement the GPS pseudorange and pseudorange-rate ...
Development of a Multi-mode Adaptive Controller and Investigation of Gain Variations with Speed and Balance Changes
(2014-03-20)
Magnetic bearings offer a number of advantages over conventional rolling element bearings. Magnetic bearings provide support for rotating systems through magnetic levitation rather than by mechanical contact, nearly ...
Effect of Reflow Process on Glass Transition Temperature of Printed Circuit Board Laminates and Model for Prediction of Package-on-Package (PoP) Warpage and the Effect of Process and Material Parameters
(2013-12-04)
The effect of temperature exposure encountered both during assembly and in fielded products, has a known influence on glass transition temperature of printed-circuit board (PCB) laminate materials. Printed circuit board ...
