Exploratory Studies Of Convective Flows Due To Arc Tracking
(Aerospace Engineering, 2007-09-17)
The objective of the research was to develop an understanding of how a flame propagates through an electronic enclosure. FLUENT®, a Navier-Stokes solver, was chosen due to its widespread commercial use, the availability ...
Design, Analysis And Development Of A Morphable Wing Structure For Unmanned Aerial Vehicle Performance Augmentation
(Mechanical Engineering, 2007-09-17)
In this research, we propose mechanisms to continuously morph a wing from a lower aspect ratio to a higher and to further extremities of a gull and an inverted-gull configuration. The mechanism comprises of a linear actuator ...
Autonomous And Cooperative Multi-UAV Guidance In Adversarial Environment
(Aerospace Engineering, 2007-08-23)
The research presented in this dissertation is aimed at developing
rule-based autonomous and cooperative guidance strategies for UAVs to
perform missions such as path planning, target tracking and rendezvous
while ...
Air Jet Impingement For Levitation
(Mechanical Engineering, 2007-08-23)
Traditional part acquisition methods such as vacuum cups and robotic grippers do not meet the handling needs of truly fragile materials, because both of these methods require surface contact. An alternative to these ...
Polymer Tube Embedded In-plane Micropump: Design, Analysis And Fabrication
(Mechanical Engineering, 2007-08-23)
This thesis presents the design, analysis, and fabrication of a novel polymer tube embedded in-plane micropump. The key component of the proposed micropump is a Parylene polymer tube that is embedded into the trench of a ...
MEMS Packaging: Fluxless Soldering and Reliability Assessment
(Mechanical Engineering, 2007-08-23)
This thesis presents process development and reliability assessment of the fluxless packaging of the MEMS devices. This packaging consists of metallized Kovar package with side wall of same material and circular holes for ...
Failure Analysis Of Composite Laminates With A Hole By Using Finite Element Method
(Mechanical Engineering, 2007-08-23)
Predicting the strength of a given laminate has been extensively studied. There have been several fracture models proposed but still the immense tests of composite laminates are still needed. Different material systems or ...
The Thermal Characteristics Of Liquid-heat-spreader
(Mechanical Engineering, 2007-08-23)
The present study is an experimental research of a liquid-heat-spreader (LHS) with saturated water at ~2.29 psia. A LHS, indirect liquid cooling module, was successfully fabricated using thin copper blocks and copper tubes ...
Thermal Enhancement Of Stacked Dies Using Thermal Vias
(Mechanical Engineering, 2007-08-23)
Following Moore's law, the number of transistors on a die continues to rise and has recently exceeded a billion on high end processors. In light of the convergence of technology, power requirements is becoming a serious ...
Frequency Response Approximation Methods Of The Dissipative Model Of Fluid Transmission Lines
(Mechanical Engineering, 2007-08-23)
This thesis introduces an accurate and efficient method of obtaining a linear approximation for a nonlinear model of a complete fluid transmission line system using Matlab® Signal Processing Toolbox and Symbolic Math Toolbox ...
