Earth-abundant electrocatalysts for solar hydrogen production from water
Photoelectrochemical water splitting and photovoltaic electrolysis, are two processes that aim to use widely available resources like water and sunlight in providing hydrogen as a clean renewable energy for the world. The ... -
User-aware performance and energy management for interactive, multi-tasking mobile systems
(2019-06-18)Billions of mobile devices aim to satisfy users through fast interaction and long battery life. To provide high quality-of-service (QoS) to users, the performance of mobile processors has significantly increased over the ... -
All's fly in love and war
Alcoholism is a serious and widespread disorder that has a complex pathophysiology and can cause extreme changes in behavior. These changes in behavior arise from alcohol affecting the neurobiological systems in an organism. ... -
Examining art professional development : how contemporary art museum programming impacts educators
(2019-05-08)This study examined the impact of art professional development and what teachers gain from their professional development experience. The purpose of this study was to investigate what teachers identify as valuable in a ... -
Theoretical and numerical study on fracture mechanics of hydrogels
(2019-05-07)Hydrogels consist of cross-linked polymer chains and water molecules. Due to the coupling between deformation of the polymer network and diffusion of the solvent molecules, the fracture behavior of hydrogels is quite ... -
Methods for solving Hamilton-Jacobi-Bellman equations
(2019-06-21)The goal of this thesis is to present two frameworks for the computation of the solutions of Hamilton-Jacobi-Bellman (HJB) equations. In Chapter 2, we present a framework for computing solutions to HJB equations on smooth ... -
Durative aspect markers in modern Arabic dialects : cross-dialectal functions and historical development
This study explores the durative aspectual forms in modern spoken Arabic dialects. It analyzes and compares the synchronic functions and proposes possible paths of diachronic development for the majority of attested durative ... -
Teaching while Black : analysis of (in)authenticity among Black women faculty in the academy and Black communities
Teaching While Black: Analysis of (In)Authenticity among Black Women Faculty in the Academy and Black Communities investigates how Black women faculty understand their Black identities by defining Black (in)authenticity ... -
Modeling and analysis of wireless networks with correlation and motion
(2019-06-13)The use of stochastic geometry allows the analysis of the typical performance of a wireless network. Specifically, under a stationary framework, the network performance at a typical receiver represents the network performance ... -
Applications of network optimization in cybersecurity and service parts logistics
(2019-05-09)We develop and analyze novel network-based optimization models for two very important network-related applications: cybersecurity and service parts logistics. We consider one cybersecurity network problem and two service ... -
Product market competitiveness and return dynamics
(2019-05-10)This dissertation examines whether stock performance of rivals is informative about a firm’s future stock return, and how the strength of predictability relates to product market competitiveness. My analysis reveals a ... -
Design and evaluation of agent implementation architectures for efficient deployment of agent technologies
(2004-12-18)The use of multi-agent systems to model and control complex domains has increased. This research offers a method and tool for the creation and evaluation of implementation-specific multi-agent system architectures. The ... -
The influence of post-spacing density of DEMs derived from LIDAR on flood modeling
(2004-05-22)The primary objective of the research is to determine the optimal post-spacing for LIDAR-derived digital elevation models (DEMs) that is required to achieve different levels of accuracy in the prediction of flood risk using ... -
The relationship between media coverage of education and education policy : a Texas case study
(2004-12-18)School finance reform was a widely debated issue in Texas in spring 2004. It appeared in the newspaper headlines and topped the policy agendas of the governor and other state leaders. In April, the governor called a special ... -
Scalable virtual memory via tailored and larger page sizes
(2019-05-10)Main memory capacity continues to soar, resulting in TLB misses becoming an increasingly significant performance bottleneck. The 4KB default minimum page size in architectures like x86 is decades old and hampers future ... -
Characterization of Polyolefin – Alumina compounded mix for FDC processing
(2000)Fused deposition of ceramics (FDC) uses thermoplastic binder and ceramic blend as feed material. The geometry of the fused deposition machine restricts the workability of the FDC feed material, which is in the form of a ... -
Mechanosensing and early biofilm development in Pseudomonas aeruginosa
Biofilms are communities of sessile microbes that are phenotypically distinct from their genetically-identical, free-swimming counterparts. Biofilms initiate when bacteria attach to a solid surface, as this attachment ... -
The path to virtue : Rembrandt’s Jerome as repentant sinner and scholar
(2019-05-08)Over the course of his career, the artist Rembrandt van Rijn produced eight prints depicting St. Jerome, a fourth-century ascetic and theologian. In this thesis, I examine why Rembrandt chose Jerome to represent so often ... -
Three-dimensional Alumina Photonic Bandgap Structures: Numerical Simulation and Fabrication by Fused Deposition of Multimaterials
(2000)Three-dimensional photonic bandgap (PBG) structures using alumina (Al2O3) as the high permittivity material were modeled and fabricated. A finite element method and a realtime electromagnetic wave propagation software ... -
The relative impact of within-class model misspecifications on enumeration accuracy in latent profile and factor mixture models
(2019-05-10)Latent profile analysis (LPA) and factor mixture modeling (FMM) are frequently used approaches to detecting latent classes, which compare several models that differ in the number of classes estimated. Numerous enumeration ...
