Microstructural effects on fracture behavior of particulate composites: Investigation of toughening mechanisms using optical and boundary element methods
(2006-08-15)
Particulate polymer composites are used in a variety of engineering applications. These are generally two phase materials with polymeric phase reinforced by a filler phase to improve overall mechanical, thermal and/or ...
Design Optimization and Health Monitoring for Multi-Directional Composite Flywheel Energy Storage Systems
(2006-08-15)
Flywheels are used to store kinetic energy through the rotation of an inertial mass, which usually rotates at very high speeds. Generally, that energy can be extracted (using a motor-generator system) in the form of ...
Torsionless Modules and Minimal Generating Sets for Ideals of Integral Domains
(2006-08-15)
This is a treatise of relationships between the number of elements necessary to generate the ideals of a domain and the
torsionless modules of that domain. Three types of domains are
identified according to natural ...
Mixed Groups with Decomposition Bases and Global k-Groups
(2006-08-15)
This thesis is devoted to proving assertions made without proof by Paul Hill and Charles Megibben in their fundamental papers regarding knice subgroups and the Axiom 3 characterization of global Warfield groups. The main ...
Evaluation of Restraint Stresses and Cracking in Early-age Concrete with the Rigid Cracking Frame
(2005-08-15)
Early-age cracking problems are common in a wide variety of concrete structures, ranging from bridge decks and piers, to pavements used for highways and airport runways. Numerous surveys conducted by state and federal ...
A-Stability For Two Species Competition Diffusion Systems
(2006-08-15)
My dissertation research focuses on establishing the structural
stability of the attractor ($\mathcal{A}$-stability) via Morse-Smale
property for diffusive two-species competition systems
\begin{equation}
\label{abst ...
Fiscal Policy and the Growth of Foreign Direct Investment in Sub-saharan Africa (Selected Countries: Ghana, Kenya, Nigeria, and South Africa)
(2005-12-15)
This study evaluates the impacts of fiscal policy on foreign direct investment (FDI) in the Sub Saharan Africa (SSA) region, focusing on the selected countries of Ghana, Kenya, Nigeria, and South Africa. The study further ...
Simbuilder: An Investigation and Usability Study Of Novice Programming Techniques
(2005-12-15)
In many existing programming languages, novices always find it difficult to transform their mental plan to terms compatible with the computer. By analyzing the ways users think to solve their daily problems and designing ...
Development of an Augmenting Navigational Cognition System
(2005-12-15)
Social isolation for persons with cognitive impairments due to aging and/or disease is common and widespread. Those people who have diseases such as early Alzheimer’s and dementia tend to forget what they have to do to ...
Hydrothermal Syntheses, Structures, and Properties of New Iodate and Selenite Compounds of Transition Metals, Lanthanides, and Actinides
(2007-12-15)
Iodate and selenite anions possessing a nonbonding, but stereochemically active lone pairs of electrons, were selected as building blocks to produce new compounds with noncentrosymmetric structures, a prerequisite for ...
Studies to Elucidate the Mechanism of Reduced Flavin Transfer in the Alkanesulfonate Monooxygenase System from Escherichia coli
(2007-12-15)
The two-component alkanesulfonate monooxygenase system utilizes reduced flavin as a substrate to catalyze a unique desulfonation reaction during times of sulfur starvation. The flavin reductase (SsuE) provides reduced ...
Polymorphism in chicken immune response genes and resistance to disease
(2007-12-15)
Genetic resistance to a number of viral pathogens has been linked to polymorphisms in genes of the immune system. Among these are the genes of the major histocompatibility complex (MHC) and those induced by the type I ...
Geographic Variation in the Yellow-throated Warbler (Dendroica dominica)
(2007-12-15)
I examined how variation within the yellow-throated warbler (Dendroica dominica) relates to geography. The yellow-throated warbler is a common neotropical migrant with a breeding range confined to the southeastern United ...
Natural History and Conservation of the Eyelash Palmpitviper (Bothriechis schlegelii) in Western Panamá
(2007-12-15)
The focus of this thesis was to examine various components of the natural history,
ecology, and conservation biology of the Bothriechis schlegelii. The sections that follow
include studies of foraging ecology, demography, ...
Hydromorphology and Plinthite Characterization of Some Alabama Coastal Plain Soils
(2007-12-15)
Estimating seasonal high water tables (SHWTs) within soils by the evaluation of redoximorphic features is critical for soil interpretations. Certain redoximorphic features indicate contemporary moisture regimes, while ...
Evaluation of Feed Efficiency Traits with Post-Weaning Growth and Ultrasound Traits in Central Test Bulls
(2007-12-15)
Since 1978, individual feed intake has been measured on bulls (n = 2,180) consigned to the Auburn University Bull Test along with weights, heights, scrotal circumference and ultrasound carcass traits. Test length since ...
Management dependent soil properties of cultivated versus non-cultivated southeastern Coastal Plain ecosystems
(2007-12-15)
Management dependent properties describe dynamic soil quality. Comparisons of disturbed to reference sites are not extensive in the southeastern (SE) U.S. due to scarcity of undisturbed land. Objectives of this study ...
Evaluation of Black Oat (Avena strigosa schreb.) Germplasm
