Thermal Electrochemical Dynamic Modeling of Sealed Lead Acid Batteries
(2009-08-06)
Limitations to battery technology ranks second as the most vital problem facing the electronic and mechanical engineering industry in the future. The life span and performance of batteries specifically SLI (Starting – ...
Dynamic Modeling of Two-Phase Heat and Vapor Transfer Characteristics in a Gas-to-Gas Membrane Humidifier for Use in Automotive PEM Fuel Cells
(2009-11-19)
Due to the recent negative outlook on the availability of cheap, long term energy supplies from non-renewable resources, several technologies have been proposed and revisited as possible solutions to the current energy ...
Reliability of Lead-Free and Advanced Interconnects in Fine Pitch and High I/O Electronics Subjected to Harsh Thermo-Mechanical Environments
(2009-09-11)
Industry is moving towards lower cost, increased functionality, and miniaturized electronics placed in ever closer proximity of higher operating temperatures, typical of harsh environments. In this thesis, three aspects ...
Experimental Investigation of Thermo-Hydraulic Characteristics of Two-Phase Flow of FC72 in Microchannel Heat Sinks
(2009-11-20)
Advances in electronics such as chip level integration and die stacking have led to a bottleneck in further development since dissipation of the resulting high heat fluxes continues to be a challenge. Due to the tremendous ...
A Study of Elastic Plastic Deformation of Heavily Deformed Spherical Surfaces
(2009-11-20)
This work uses a finite element analysis and analytical equations to model elastic-plastic and fully plastic large deformations of spheres in contact with rigid flat surfaces. The case considered here is of a deformable ...
A Software and Hardware System for the Autonomous Control and Navigation of a Trained Canine
(2009-07-20)
This dissertation demonstrates the autonomous command and navigation of a trained
canine to multiple waypoints. A system is described consisting of a canine that can be
guided autonomously to a number of waypoints by an ...
Material behaviour of mixed formulation solders
(2009-12-18)
The transition from tin-lead to lead free soldering in the electronics manufacturing industry has been in progress for the past 10 years. In the interim period before lead free assemblies are uniformly accepted, mixed ...
Adaptive Disturbance Rejection and Stabilization for Rotor Systems with Internal Damping
(2009-02-23)
Advanced rotor systems today consist of a lightweight rotor supported by radial active
magnetic bearings (AMB). These systems are widely used in flywheel applications and in
other fields where high rotational speeds are ...
