Modeling of Frictional Gas Flow in a Piezoelectrically Actuated High-Pressure Microvalve for Flowrate Control
(2005-12-15)
One-dimensional modeling of frictional compressible gaseous flow through a high-pressure piezoelectrically-actuated microvalve is studied. Focusing on the micro-scale gap between the boss and seat plates, variations of ...
Overlooked: Dominant Ideology, Limestone County, Alabama Newspapers, and TVA Family Relocation, 1934-1936
(2005-08-15)
The Tennessee Valley Authority’s (TVA’s) construction of Wheeler Dam necessitated the flooding of 52,000 acres of land in Lauderdale, Limestone and Morgan counties in north Alabama. TVA purchased this land from the 835 ...
A Robust Software Radio Testset for Research and Laboratory Instruction
(2005-12-15)
Since the mid-1990s, communication technology has advanced dramatically, making it possible to achieve high data rates for both enterprise and individual users. The rapid and widespread deployment of wireless communications ...
3D Device Simulation of SEU-Induced Charge Collection in 200 GHz SiGe HBTs
(2005-12-15)
This thesis presents three dimensional device simulations of SEU (single-event
upset)-induced charge collection in 200 GHz SiGe HBTs. The device was constructed
and simulated using Davinci.
The charge collected by each ...
Interdependence Theory, China and American Security Interests
(2006-05-15)
This research examines how the economic relationship between the United States and China impacts the potential for dyadic conflict. We employed Interdependence Theory to explain this relationship. Our purpose is to examine ...
Methods for Minimizing Navigation Errors Induced by Ground Vehicle Dynamics
(2006-05-15)
A navigation system was designed using an extended Kalman filter for an autonomous ground vehicle competing in the 2005 DARPA Grand Challenge. An overview of this system is provided, and errors in the navigation solution ...
Vibration and Acoustical Properties of Sandwich Composite Materials
(2006-05-15)
In applications where the use of lightweight structures is important, the introduction of a viscoelastic core layer, which has high inherent damping, between two face sheets, can produce a sandwich structure with high ...
Thermo-mechanical Reliability Models for Life Prediction of Area Array Electronics in Extreme Environments
(2006-05-15)
The increasing functionality in modern microelectronics requires more complexity in less space and more reliability at lower cost. Demands on miniaturization have lead to the evolution of several types of area array packages ...
Characterization and Prediction of Material Response of Micro And Nano-Underfills for Flip Chip Devices
(2006-05-15)
Silica particles are used as a filler material in electronic underfills to reduce coefficient of thermal expansion of the underfill-epoxy matrix. In traditional underfills, the size of silica particles is in the micrometer ...
Passive Pendulum Balancer for Rotor Systems
(2006-05-15)
Automatic, passive self-balancing systems are important tools for reducing the effects of synchronous vibration in a variety of rotating machinery. Such systems are ideally capable of precise balancing, subject to certain ...
Iterative processes generating dense point sets
(2006-05-15)
The central problem of the thesis is the question of denseness of
certain sets of points in the plane. All of the following results
are joint with A. Bezdek. We consider point sets P, not a subset
of a line, having the ...
Concerning a Problem of K. Kuratowski
(2006-05-15)
Suppose (S,T) is a topological space and A is any subset of S. Then the functions f and g from the power set of S, P(S), into P(S) are defined as: f(A) is the closure of A and g(A) is the complement of A. In this thesis, ...
A Brief Exploration of the Sorgenfrey Line and the Lexicographic Order
(2006-05-15)
The author will compare properties of the usual topology on the real line with the properties of the Sorgenfrey Line. After that she will look at properties of the Lexiographic Order on the reals cross [0,1]. The main ...
On the role of 1-LC and semi 1-LC properties in determining the fundamental group of a one point union of spaces
(2006-05-15)
Concerning the fundamental group of spaces written as a union of two topological
spaces, the result by Seifert and van Kampen is well known and frequently
used. Over the years there have been various theorems published ...
Microstructure – Mechanical Property Relationships in Transient Liquid Phase Bonded Nickel-Based Superalloys and Iron-based ODS Alloys
(2006-05-15)
The research work presented here discusses the microstructure-mechanical property relationships in wide gap transient liquid phase (TLP) bonds, between the single crystal nickel-base superalloy CMSX-4 and two polycrystalline ...
Transient Liquid Phase Bonding of Ferritic Oxide Dispersion Strengthened Alloys
(2006-05-15)
Oxide dispersion strengthened (ODS) alloys possess excellent properties including resistance to oxidation, corrosion, creep and thermal fatigue. In addition, ferritic ODS alloys exhibit resistance to void swelling and are ...
