Cold Cathodes for Applications in Poor Vacuum and Low Pressure Gas Environments: Carbon Nanotubes Versus Zinc Oxide Nanoneedles
(2006-05-15)
Effects of gas pressure on the electron field emission (FE) properties of zinc oxide (ZnO) nanoneedles and carbon nanotubes (CNTs) were investigated. The FE properties for ZnO nanoneedles almost fully recovered after being ...
Practically Realizing Random Access Scan
(2006-05-15)
The number of clock cycles in a serial scan (SS) test is often prohibitive as the number of flip-flops (FF) increases. Besides, scan-in and scan-out sequences result in unwanted circuit activity. This increases the test ...
Efforts Towards the Design and Development of an Electromagnetic Induction Sensor Optimized for Detection and Discrimination of Unexploded Ordnance
(2006-05-15)
This thesis provides a detailed description of efforts towards the development of a time domain electromagnetic induction (EMI) system optimized for detection and discrimination of Unexploded Ordnance (UXO). A time domain ...
Lattice-Reduction Aided Linear Equalization For Wireless Communications Over Fading Channels
(2006-05-15)
Modern wireless communications ask for high data rate, high transmission performance and low complexity. High data rate induces frequency-selective channels because of the relatively shorter symbol duration than the delay ...
Perfomance Analysis of 802.11b Networks
(2006-05-15)
Wireless local area networks (WLANs), especially those incorporating the 802.11b standard, have experienced rapid evolution and unprecedented widespread deployment during the past few years. Increasing research led to the ...
Particle Swarm Optimization Applied to the Design of a Nonlinear Control
(2006-05-15)
A method of searching for a tuning of an input to state linearizing controller is
presented. The problem of ?nding the appropriate weights of the control law’s terms
is treated as an optimization problem. Given the highly ...
Independence Fault Collapsing and Concurrent Test Generation
(2006-05-15)
The objective of this work is to find suitable targets for Automatic Test Pattern Generation (ATPG) such that a minimal test set is obtained for a combinational circuit. Original concepts of independence fault collapsing ...
Modeling a Fuel Cell System for Residential Dwellings
(2006-05-15)
Fuel cells produce electricity by combining hydrogen and oxygen to form water. Fuel cells have unique electrical characteristics and performances that warrant examination and discussion. From the hydrogen source to the ...
Predicting Generator Coupling Using Power System Impedance Matrices
(2006-05-15)
The combination of power flows on multiple lines constitutes a flowgate. Transmission flowgates are one tool being used to deal with wide-area stability issues because experience with dynamic simulation suggests that ...
Novel Techniques for the Design and Characterization of Electromagnetic Devices with Application to Multilayer Structures and Waveguide Filters
(2006-05-15)
In this work, optimization methods are presented for the analysis of inverse and
design problems in electromagnetics. The current and future demands placed on design
engineers necessitate the hybridization of forward ...
Electromagnetic induction systems for discrimination among metallic targets
(2006-05-15)
This dissertation discusses the ability of time- and frequency-domain electromagnetic induction (EMI) systems to discriminate unexploded ordnance (UXO) from clutter. The chief contribution of this work is to demonstrate ...
Fabrication and Assembly of Ultra Thin Flexible Active Printed Circuits
(2006-05-15)
Tremendous attention has been focused on flexible printed circuits for their light weight, minimized dimension and three dimensional packaging capabilities. However, the traditional flexible circuit fabrication and assembly ...
Automatic Detection of Software Security Vulnerabilities in Executable Program Files
(2005-08-15)
Secure programming describes those techniques that software developers use to provide security features in their applications. In addition to these techniques, software practitioners use static code security checkers to ...
Fluid Flow and Heat Transfer in Cavities with Inlet and Outlet Ports: Effect of Flow Oscillation and Application to Design of Microvalves
(2005-12-15)
A Computational Fluid Dynamics (CFD) code is developed and tested to solve the two-dimensional form of the Navier-Stokes and energy equations. The flow field and heat transfer in a square cavity with inlet and outlet ports ...
Drawn Into Unknown Lands: Frontier Travel and Possibility in Early American Literature
(2005-12-15)
This dissertation explores the symbolic meanings contained in literary depictions of journeys to the American frontier written during the late 1700s and early 1800s. I argue that these depictions work to create and advance ...
High Tunnel Production of Tomatoes and Snapdragons for Season Extension in Southeastern Alabama
(2006-05-15)
Tomato and snapdragon production were evaluated for high tunnel production in southeastern Alabama during the spring and fall production cycles for season extension feasibility. ‘BHN 640’, ‘FLA 91’, ‘Sunleaper’, and ...
Accelerated Production of Tree-form Crapemyrtle
(2006-05-15)
Most cultivars of crapemyrtle are vigorous growers under nursery conditions;
however, some cultivars begin flowering by early summer, resulting in suppressed
vegetative growth, particularly height growth, a problem often ...
The Effects of Color Plastic Mulches and Row Covers on the Growth and Production of Okra and Summer Squash
(2006-05-15)
Okra [Abelmoschus esculentus (L.) Moench‘Clemson Spineless’] and summer squash [Cucurbita pepo (L) ‘Prelude II’] was grown on an Orangeburg sandy loam soil in Shorter, AL. Okra and summer squash were direct seeded in single ...
Evaluation of a High Tunnel Production System as a Means of Enhancing Market Opportunities for Alabama Growers
(2006-05-15)
High tunnels (HT) can reduce negative environmental strains on crop production and have been shown to extend the growing season for many small fruits and vegetables. Because HT’s require relatively low initial investment ...
