The Revolt of the Majors: How the Air Force Changed After Vietnam
(2008-09-09)
During the Vietnam War, the United States Air Force had performed inconsistently and after the war was faced with a number of challenges. Many of the Air Force senior leadership felt that the challenges could be resolved ...
Relationships between large benthic foraminifera and their seagrass habitats, San Salvador, Bahamas
(2008-09-09)
Vegetation beds are important in the ecology and depositional history of platform carbonates. The vegetation itself, frequently dominated by the seagrass Thalassia, has a low preservation potential, but plants and benthic ...
Independence Fault Collapsing and Concurrent Test Generation
(2008-09-09)
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 ...
Electromagnetic induction systems for discrimination among metallic targets
(2008-09-09)
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 ...
Groundwater Geochemistry, Geology, and Microbiology of Arsenic-contaminated Holocene Alluvial Aquifers, Manikganj, Bangladesh
(2008-09-09)
A multi-disciplinary study, using integrated aspects of geology, groundwater geochemistry including carbon isotope geochemistry, scanning electron microscopy, energy dispersive spectroscopy, and geochemical modeling, reveals ...
Fabrication and Assembly of Ultra Thin Flexible Active Printed Circuits
(2008-09-09)
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 ...
Evaluation of a High Tunnel Production System as a Means of Enhancing Market Opportunities for Alabama Growers
(2008-09-09)
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 ...
Predicting Generator Coupling Using Power System Impedance Matrices
(2008-09-09)
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 ...
An Accurate CMOS Four-Quadrant Analog Multiplier
(2008-09-09)
Analog multipliers are used in communication circuits, neural networks as well as frequency doublers, RMS circuits and phase detectors. High linearity is the prime issue for multipliers in conventional applications like ...
Modeling a Fuel Cell System for Residential Dwellings
(2008-09-09)
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 ...
