Insights into computational methods for surface science and catalysis
(2021-12-06)The fundamental understanding of both the reactions at catalytic surfaces and the ways in which these surfaces change throughout a catalytic cycle and lifetime are important for both academic and industrial disciplines. ... -
Investigating thermodynamics and kinetics of hydrate phase change phenomena using experimental and machine learning tools
(2021-12-07)Hydrates are ice-like crystalline solids which form under high pressure and low-temperature conditions from water (forming a cage of host molecules) and another liquid or gas (guest molecule). Hydrates can enable numerous ... -
Plastic flow and microstructure evolution in niobium at elevated temperatures
(2021-12-09)Plastic flow and microstructure evolution are investigated at elevated temperatures in two unalloyed niobium sheet materials, Type 1 and Type 2 as designated in ASTM B393-18. Tensile tests are conducted at temperatures ... -
Computational automation for efficient design of acoustic metamaterials
(2022-01-26)Acoustic metamaterials (AMMs) are an exciting technology because they are capable of responding to vibrations in ways that are impossible to achieve with conventional materials. However, realization of AMMs requires ... -
Interphase power flow control and voltage regulation in distribution systems with high photovoltaic generation
(2022-02-07)As distribution systems accommodate higher photovoltaic (PV) penetration, traditional voltage controls face increasing challenges in regulating voltages to within voltage tolerance limits. The voltage issues in the ... -
Design of strategic evacuations with conventional and self-driving vehicles
(2021-12-09)This dissertation delivers efficient strategies for evacuating Houston and Galveston neighborhoods in the Texas Gulf Coast to various safe destinations. Effective network assignment and vehicle-operation strategies are ... -
Management and operation of emerging mobility services
(2021-12-09)Mobility services, such as ridesourcing and e-scooters, are changing the transportation landscape. These services are often unregulated and their impact on traffic or alternative modes is not well understood. In this ... -
The father of Rochester
(2005-05-21)A short fiction and poetry collection written by the author over the course of her three years of study while attending the James A. Michener Center for Writers at the University of Texas at Austin -
Structural reliability analysis for vessel impact on bridges
(2005-05-21)The collapse of the Queen Isabella Causeway in 2001 due to a vessel collision was an alarming message to the state of Texas that vessel impact on bridges is a serious issue and may need to be considered for all bridges ... -
Numerical prediction of underwater noise induced by non-cavitating/cavitating propellers
(2022-05-11)In this work, a systematic procedure of analyzing marine propeller performance and its underwater acoustics is delineated. The main focus is laid on the numerical prediction of hull pressure fluctuations and far-field ... -
Exercise training reduces reactive oxygen species production in myocardial mitochondria of rat hearts
(2005-05-21)Mitochondria are recognized to be a major cellular site of reactive oxygen species (ROS) production which is elevated during exercise. Exercise is also known to provide cardioprotection against ischemia/reperfusion injury ... -
Multiscale visualization of chemical enhanced oil recovery
(2021-12-09)Chemical enhanced oil recovery (EOR) involves injecting chemicals such as surfactants, polymers, and alkalis into depleted oil reservoirs to increase oil recovery. Experimental tools such as corefloods and micromodels ... -
Enhanced oil recovery using low tension gas flooding in high salinity, low permeability carbonate reservoirs
Chemical enhanced oil recovery (EOR) in carbonate reservoirs is a technically and economically challenging process. Low-Tension Gas flooding is developed as an attractive alternative to conventional EOR methods for application ... -
Enhancements to solving constraints written as imperative predicates
(2021-11-23)Modern software systems rely on automated testing and reliability techniques to detect bugs during development and to make the system resilient to runtime failures. Logical constraints that characterize properties of ... -
Confusion as an emotional metacognitive experience : students’ voices making sense of confusion during learning
(2021-12-08)Confusion is a frequent and important experience accompanying the learning process, characterized as both affective and cognitive, and especially prevalent during complex learning. Although research has highlighted confusion’s ... -
Gardening the landscape and bushwhacking through the swampland : exploring the consequences of quantum gravity for cosmic inflation
(2022-02-07)This dissertation consists of five chapters. The first broadly and briefly orients the reader through an introduction to inflationary cosmology, and why we might expect multi-field inflation to take place. The next four ... -
Whether, to whom, and how : an investigation of daily experiences of discrimination and adolescents’ well-being
(2021-12-09)Discrimination is prevalent in the lives of adolescents, and it is also detrimental to adolescents’ well-being. The two-study dissertation employed a daily diary design to examine whether (study 1 and 2), for whom (study ...
