Triangulations and Simplex Tilings of Polyhedra
(2012-07-09)
This dissertation summarizes my research in the area of Discrete Geometry. The particular problems of Discrete Geometry discussed in this dissertation are concerned with partitioning three dimensional polyhedra into ...
Amalgamations and Detachments of Graphs and Hypergraphs
(2012-07-09)
A \textit{detachment} of a graph $H$ is a graph obtained from $H$ by splitting some or all of its vertices into more than one vertex. If $g$ is a function from $V(H)$ into $\mathbb {N}$, then a \textit{$g$-detachment} of ...
Rank-Based Regression for Nonlinear and Missing Response Models
(2012-07-09)
This dissertation is mainly concerned with the rank-based estimation of model parameters in complex regression models: a general nonlinear regression model and a semi-parametric regression model with missing responses. For ...
Measurement of Alcohol Use at a Historically Black College/University (HBCU)
(2012-07-09)
Previous studies have reported that African-American students attending HBCUs consume less alcohol and experience fewer negative consequences compared to students attending other public colleges and universities (Fowler, ...
Teachers’ Concerns, Attitudes, Beliefs, and Pedagogical Practices as it Relates to Technology Integration
(2012-07-02)
Education is the catalyst for preparing students to become productive members of society. Developing skills and knowledge students will need to compete globally is the charge excepted by educators at every level. The ...
Correlates of Same-Sex Romantic Relationship Satisfaction: The Roles of Parental Support and Outness
(2012-07-02)
The purpose of the study was to explore variables associated with romantic relationship satisfaction for members of same-sex romantic relationships. Specifically, the study explored how same-sex couple members’ romantic ...
Stars and Hyperstars
(2012-07-02)
A \textit{$k$-star} is a complete bipartite graph $K_{1,k}$, and a hypergraph $G=(X,\mathcal{E})$ is a \textit{hyperstar} with center $C$ if $\displaystyle C\subseteq\bigcap_{E\in\mathcal{E}}E$. Given (hyper)graphs $G$ ...
Destination perceptions of Chinese tourists: A comparison between Japan and South Korea
(2012-07-02)
It has been widely accepted that competitive advantage is the key to the success of organizations, regions and countries (Porter, 1980). In the tourism industry, a country’s potential depends on its ability to maintain ...
Nonlinear Control of a Robot-Trailer System Using a Hybrid Backstepping-linearizing Approach
(2012-07-02)
In this work, the author develops a nonlinear controller to stabilize an autonomous wheeled robot and trailer system. A dynamic model based on robot-trailer kinematics that has previously proven sufficient for state feedback ...
Factors Influencing Catenary Behavior in Ductile Steel-Framed Structures
(2012-07-02)
Historical precedent has established progressive collapse as a phenomenon characterized by the potential for extreme structural damage and loss of life. In an attempt to mitigate such behavior in conventional structures, ...
Hydro-peaking Impacts on Growth, Movement, Habitat Use and the Stress Response on Alabama Bass and Redeye Bass, in a Regulated Portion of the Tallapoosa River, Alabama
(2012-07-02)
Altered flow regimes caused by dam construction and operation can affect aquatic organisms in a variety of ways. The Tallapoosa River, in east-central Alabama, has been extensively impounded for flood control, navigation ...
Introduced Yellow Perch in Lake Martin and Yates Lake, Alabama: Interactions with Native Fishes
(2012-07-02)
Yellow perch has been introduced into Southeastern US drainages outside its native range. In Alabama, established populations now exist in Lake Martin and Yates Lake. Here, I determined how yellow perch might influence ...
Modular Balanced Graphs
(2012-07-02)
Necessary and sufficient conditions for the existence of modular balanced graphs and modular balanced bipartite graphs.
Assessment of Design Provisions for Open I-Section under Combined Flexure and Torsion
(2012-07-02)
In civil structures, the members often encounter a combined loading of flexure and torsion, which has a strong influence on the members’ behavior and capacity, especially for those beam sections with relatively weak torsional ...
Assessing Transformation of Trace Metals and Crude Oil in Mississippi and Louisiana Coastal Wetlands in Response to the Deepwater Horizon Oil Spill
(2012-06-28)
On April 20, 2010, the drilling rig Deepwater Horizon exploded in the Gulf of Mexico, resulting in the release of about 5 million barrels of crude oil into the environment. Coastal wetlands are particularly susceptible to ...
The Effects of Aging on the Reliability of Lead Free Fine-Pitch Electronics Packaging
(2012-06-26)
A direct and deleterious effect on packaging reliability has been observed during elevated temperature isothermal aging for fine-pitch ball grid array (BGA) packages with Sn-1.0Ag-0.5Cu (SAC105), Sn-3.0Ag-0.5Cu (SAC305), ...
Designing landscapes for bird conservation in the Southeastern United States
(2012-06-22)
The Southeastern United States has high conservation importance because of the region's habitat and species diversity, ecological processes, and evolutionary potential; however, it also warrants strong concern because of ...
The evolution of milk composition and lactation strategy of the Columbian ground squirrel, Urocitellus columbianus
(2012-06-19)
The evolution of parental care improved the efficiency of the reproductive process, allowing for the production of fewer offspring with a higher probability of survival. This adaptation is exemplified in the taxon named ...
