Differences in Flicker Paradigm Response Times: Change Blindness in Snake Phobics
(2005-08-15)
This study is a replication of Wheeler (2003), expanding upon his exploration of the connection between snake phobia and change blindness, a phenomenon in which individuals do not recognize changes in their immediate ...
Response-Consequence Contingency Discriminability When Positive and Negative Reinforcement Compete in Concurrent Schedules
(2005-08-15)
Four experiments were conducted to test the qualitative prediction of contingency discriminability theory that any difference in type between the consequences of concurrently available discriminated operants will heighten ...
Composite Contact Metallization on SiC for High Temperature Applications in Air
(2005-08-15)
Composite ohmic and Schottky contacts fabricated on 4H-SiC for applications in air at 350^oC are described and evaluated in this study. The ohmic contacts were fabricated on p+ implanted and n+ epitaxial materials, while ...
Logico-Mathematical Processes in Beginning Reading
(2005-08-15)
Phonemic awareness has been shown to be a foundational component that initiates children’s insight into the alphabetic principle. With the support of research, programs have been developed for children at the preschool ...
Simulation Modeling and Analysis of Printed Circuit Board Assembly Lines
(2005-12-15)
This thesis focuses on simulation modeling and analysis of printed circuit board assembly lines. The objectives of the study include assessing the feasibility of process flow logic and relative impact of changing line ...
Development of a More Sustainable Sweetpotato Production System in Alabama
(2005-12-15)
Field experiments were conducted from 2003-2005 to evaluate the influence of grass and legume cover crops, no-tillage, and varying rates of nitrogen on commercial sweetpotato production. Cover crops used for the no-till ...
The Intent and Fulfillment of the Morrill Act of 1862: A Review of the History of Auburn University and the University of Georgia
(2005-12-15)
What was the intent of Morrill Act, and what does it mean to be a land grant university? The principal purpose of the Morrill Act, as relevant to the twenty-first century land grant institutions, was to increase the ...
GENERTIA: A System for Vulnerability Analysis, Design and Redesign of Immunity-Based Anomaly Detection System
(2006-12-15)
The principles of immunology have been applied to the design and implementation of artificial systems and algorithms for solving a broad range of mathematical and engineering problems, which results in a new computation ...
Coupling Transport Codes with Geochemical Models
(2006-12-15)
Multi-dimensional reactive transport models are needed for understanding the fate and transport of the metal contaminants in groundwater aquifers. The goal of this research is to develop a framework for coupling the MINTEQ ...
Laboratory Refinement of 4.75 mm Superpave Designed Asphalt Mixtures
(2006-12-15)
In 2004 a pooled fund study was initiated to refine mix design criteria for 4.75mm NMAS Superpave designed mixes and field validate design criteria. Nine states were participants in this study, Alabama, Connecticut, Florida, ...
Determination of Elastic Constants and Damage in Ceramic Matrix Composites Using Ultrasonic Wave Speed Measurements
(2006-12-15)
MATLAB programs were developed to compute the elastic constants and damage of ceramic matrix composites using ultrasonic wave speed measurements. The matrix of elastic stiffnesses, C, relates the material stresses and ...
Understanding the Flow and Mixing Dynamics of Saline Water Discharged into Coastal Freshwater Aquifers
(2006-12-15)
Typically the origin of saltwater intrusion into coastal aquifers has been attributed to the reduction of freshwater flux (or head) in the aquifer. This intrusion is the most common natural source of saltwater contamination ...
Comparison of New Technology for Measuring Ride Quality
(2006-12-15)
Ride quality of a pavement is quantified by a statistical index. The statistical index and the profile device used to assess the index are major variables in pavement smoothness. Due to the wide range of these variables ...
Characterization of the iron center in cysteine dioxygenase and kinetic analyses of flavin binding by the alkanesulfonate flavin reductase
(2006-12-15)
Cysteine dioxygenase (CDO) and the flavin reductase, SsuE, are both important proteins in sulfur metabolism. CDO catalyzes cysteine oxidation which is a key step in cysteine metabolism in mammalian systems. SsuE is a flavin ...
