Vibrational Spectra and Potential Function of Tetrachlorocyclopropene

Description: The laser Raman spectra of tetrachlorocyclopropene in the liquid and solid phases have been recorded and vibrational assignments are presented. These results along with root mean squared vibrational amplitudes from electron diffraction data have been employed in a normal coordinate analysis in which a 19 parameter potential function is refined. This potential function, originally expressed in terms of compliance constants, is then used to derive the corresponding conventional and relaxed force … more

VLSI Architecture and FPGA Prototyping of a Secure Digital Camera for Biometric Application

Description: This thesis presents a secure digital camera (SDC) that inserts biometric data into images found in forms of identification such as the newly proposed electronic passport. However, putting biometric data in passports makes the data vulnerable for theft, causing privacy related issues. An effective solution to combating unauthorized access such as skimming (obtaining data from the passport's owner who did not willingly submit the data) or eavesdropping (intercepting information as it moves from… more

Someone to Talk to: Conversations Between Friends in a Junior High Lunch Room

Description: Quantitative studies dominate early adolescence research, a field which also lacks an understanding of communication behaviors between early adolescents. This study uses the qualitative methods of participant observation and informal interviews to observe conversations between girls in a junior high lunch room. Friendship characteristics and group socialization are discussed as they emerged from the field data. First, friendship hierarchies (best friend, close friend, and friend) may be adult-i… more

Neural Network Classifiers for Object Detection in Optical and Infrared Images

Description: This thesis presents a series of neural network classifiers for object detection in both optical and infrared images. The focus of this work is on efficient and accurate solutions. The thesis discusses the evolution of the highly efficient and tiny network Binary Classification Vision Transformer (BC-ViT) and how through thoughtful modifications and improvements, the BC-ViT can be utilized for tasks of increasing complexity. Chapter 2 discusses the creation of BC-ViT and its initial use case fo… more

Base Effects on the Thermal Decomposition of Sec-butyllithium Solutions

Description: The pyrolysis of sec-butyllithium in solution was studied in an attempt to understand the loss of stereo-specificity and the atypical kinetics that have been reported. Additionally, the effect of added lithium alkoxides was studied to determine their effects on the highly reactive sec-butyllithium substrate.

A Study of the Bacterial Flora of Food Utensils in Hardin College Cafeteria and Twenty-Five Eating Establishments in Wichita Falls, Texas

Description: The problem of this thesis consists primarily of a bacteriological survey of the eating utensils of Hardin College Cafeteria and twenty-five other eating establishments in the city of Wichita Falls, Texas. This investigation was made primarily with reference to a determination of the possible presence of typhoid and related organisms, and secondarily to an investigation of the actual presence of those bacterial organisms associated with the more common outbreaks of food poisoning.

Integrating Selective Herbicide and Native Plant Restoration to Control Alternanthera philoxeroides (Alligator Weed)

Description: Exotic invasive aquatic weeds such as alligator weed (Alternanthera philoxeroides) threaten native ecosystems by interfering with native plant communities, disrupting hydrology, and diminishing water quality. Development of new tools to combat invaders is important for the well being of these sensitive areas. Integrated pest management offers managers an approach that combines multiple control methods for better control than any one method used exclusively. In a greenhouse and field study, we t… more

Gradient-Index Metamaterial Infrared Detector for Enhanced Photo-Response and Image Quality

Description: An enhanced thermal imaging concept made possible through the development of a gradient-indexed metamaterial infrared detector that offers broadband transmission and reflection in THz waves. This thesis proposes a proof of feasibility for a metamaterial infrared detector containing an anti-reflective coating with various geometrically varying periodic metasurfaces, a gradient-indexed dielectric multilayer for near-perfect longpass filtering, and a gradient index of refraction (GRIN) metalens fo… more

Increasing Exercise in Sedentary Adults Using a Contingency and Technology-Based Management Package to Begin and Sustain New Levels of Activity

Description: Using a multiple baseline across participants with a changing criterion, this study explored and evaluated the effects of the individualized contingency management package (goal-setting, education, etc.) with sedentary typical adults while focusing on the mentoring component and the use of the technology of the exercise tracker to increase and sustain physical exercise to a level that increased health-benefiting physical activity. During initial mentoring meeting prior to the start of baseline,… more

The Effects of Contingency Type on Accuracy and Reaction Time

Description: Positive and negative reinforcement contingencies have been compared in terms of preference, but the differential effects of positive and negative reinforcement on reaction time and accuracy with other variables controlled remain unclear. Fifteen undergraduate students participated in a sound discrimination task that involved random mixed-trial presentations of positive and negative reinforcement contingencies. The participants' goal was to correctly identify whether the tone was shorter or lon… more

Post-Traumatic Symptomatology in the Luby's Shooting

Description: The role of exposure to a human-made disaster and the subsequent development of post-traumatic stress reactions were examined. Subjects included 49 males and 30 females who were variously exposed to the Luby's shooting incident in Killeen, Texas in October of 1991. Post-traumatic stress symptomatology was measured by the SCL-90R. Exposure was operationalized by using a scenario-rating scheme with independent raters estimating each subject's level of exposure. A regression and commonality analys… more

Dmitri Shostakovich and the Fugues of Op. 87: A Bach Bicentennial Tribute

Description: In 1950-51, for the bicentennial of the death of J. S. Bach, Dmitri Shostakovich wrote his collection of Twenty-four Preludes and Fugues, Op. 87. This thesis is a study of the fugal technique of Shostakovich as observed in Op. 87, in light of the fugal style of Bach as observed in The Well-Tempered Clavier, Volume One. Individual analyses of each of the twenty-four Shostakovich pieces yield the conclusion that Op. 87 is an emulation of Bachian fugal methods as observed in The Well-Tempered Clav… more

T. S. Eliot's Ash Wednesday: a Philosophical Approach to Empowering the Feminine

Description: In his 1916 dissertation, Eliot asserted that individuals were locked into finite centers and that all knowledge was epistemologically relative, but he also believed that finite centers could be transcended through language. In the essay "Lancelot Andrewes,'" Eliot identified Andrewes's "relevant intensity," a method very close to nonsensical verse. Eliot used Andrewes's Word and the impersonality of nonsense verse in Ash Wednesday. The Word, God's logos, embodied the Virgin Mary as its source,… more
