Zinc oxide (ZnO) has attracted much interest during last decades as a functional material. Furthermore, ZnO is a potential material for transparent conducting oxide material competing with indium tin oxide (ITO), graphene, and carbon nanotube film. It has been known as a conductive material when doped with elements such as indium, gallium and aluminum. The solubility of those dopant elements in ZnO is still debatable; but, it is necessary to find alternative conducting materials when their form is film or nanostructure for display devices. This is a consequence of the ever increasing price of indium. In addition, a new generation …

Shock loading is a complex phenomenon that can lead to failure mechanisms such as strain localization, void nucleation and growth, and eventually spall fracture. Studying incipient stages of spall damage is of paramount importance to accurately determine initiation sites in the material microstructure where damage will nucleate and grow and to formulate continuum models that account for the variability of the damage process due to microstructural heterogeneity. The length scale of damage with respect to that of the surrounding microstructure has proven to be a key aspect in determining sites of failure initiation. Correlations have been found between the damage …

Pulse Density Modulation- (PDM-) based class-D amplifiers can reduce non-linearity and tonal content due to carrier signal in Pulse Width Modulation - (PWM-) based amplifiers. However, their low-voltage analog implementations also require a linear- loop filter and a quantizer. A PDM-based class-D audio amplifier using a frequency-domain quantization is presented in this paper. The digital-intensive frequency domain approach achieves high linearity under low-supply regimes. An analog comparator and a single-bit quantizer are replaced with a Current-Controlled Oscillator- (ICO-) based frequency discriminator. By using the ICO as a phase integrator, a third-order noise shaping is achieved using only two analog integrators. …

Voltage Control Oscillator (VCO) is one of the most critical blocks in Phase Lock Loops (PLLs). LC-tank VCOs have a superior phase noise performance, however they require bulky passive resonators and often calibration architectures to overcome their limited tuning range. Ring oscillator (RO) based VCOs are attractive for digital technology applications owing to their ease of integration, small die area and scalability in deep submicron processes. However, due to their supply sensitivity and poor phase noise performance, they have limited use in applications demanding low phase noise floor, such as wireless or optical transceivers. Particularly, out-of-band phase noise of RO-based …

Time magazine called 1976 "the year of the evangelical" partly in response to the rapid political ascent of the previously little-known Georgia governor Jimmy Carter. A Sunday school teacher and deacon in his local church, Carter emphasized the important role of faith in his life in a way that no presidential candidate had done in recent memory. However, scholarly assessments of Carter's foreign policy have primarily focused on his management style or the bureaucratic politics in his administration. This study adds to the growing literature in American diplomatic history analyzing religion and foreign policy by focusing on how Carter's Christian …

Bayesian networks are powerful tools in system reliability assessment due to their flexibility in modeling the reliability structure of complex systems. This dissertation develops Bayesian network models for system reliability analysis through the use of Bayesian inference techniques. Bayesian networks generalize fault trees by allowing components and subsystems to be related by conditional probabilities instead of deterministic relationships; thus, they provide analytical advantages to the situation when the failure structure is not well understood, especially during the product design stage. In order to tackle this problem, one needs to utilize auxiliary information such as the reliability information from similar products …

The process of combining data is one in which information from disjoint datasets sharing at least a number of common variables is merged. This process is commonly referred to as data fusion, with the main objective of creating a new dataset permitting more flexible analyses than the separate analysis of each individual dataset. Many data fusion methods have been proposed in the literature, although most utilize the frequentist framework. This dissertation investigates a new approach called Bayesian Synthesis in which information obtained from one dataset acts as priors for the next analysis. This process continues sequentially until a single posterior …

The purpose of this project was to create a beginner-level oboe method book that provides equal attention to both the instrumental and musical concepts necessary for a beginner oboist. The existing literature for beginning oboe students focuses on two specific settings: full band classrooms, where students are playing and learning the instruments together, and private lesson settings, where one or a group of oboe students are focused on learning to play the oboe. Books written for band settings typically focus on teaching the students how to function as a part of the band, with extensive coverage of musical concepts; conversely, …

Online social networks are the hubs of social activity in cyberspace, and using them to exchange knowledge, experiences, and opinions is common. In this work, an advanced topic modeling framework is designed to analyse complex longitudinal health information from social media with minimal human annotation, and Adverse Drug Events and Reaction (ADR) information is extracted and automatically processed by using a biased topic modeling method. This framework improves and extends existing topic modelling algorithms that incorporate background knowledge. Using this approach, background knowledge such as ADR terms and other biomedical knowledge can be incorporated during the text mining process, with …

Endocrine disruptors are chemicals that interact with the hormone system to negative effect. They ‘disrupt’ normal processes to cause diseases like vaginal cancer and obesity, reproductive issues like t-shaped uteri and infertility, and developmental abnormalities like spina bifida and cleft palate. These chemicals are ubiquitous in our daily lives, components in everything from toothpaste to microwave popcorn to plastic water bottles. My dissertation looks at the history, science, and regulation of these impactful substances in order to answer the question of how endocrine disruptors appeared, got interpreted by different groups, and what role science played in the process. My analysis …

The availability and subsequent expansion in the use of online learning environments has provided a new avenue for teacher professional development: blended learning. While blended learning environments may provide attractive benefits to teachers and school administration, the impact of blended teacher professional development has been largely unexamined in the existing research. This mixed-methods study investigated professional development outcomes for 64 teachers participating in district sponsored teaching professional development, 32 in a blended course and 32 in a face-to-face equivalent of the course. Outcomes of the professional development were measured using pre- and post- instructional belief surveys, participant satisfaction surveys, and …

This study examines the representation of Asian online brides by studying the images and profiles that are advertised on Asianonlinebrides.com. To do so, I combined the history and growth of the Human Trafficking industry, the idea of the Asian “exotic OTHER,” the power and structured/constrained agency, and social construction of gender theories. In particular, I utilized a mixed methods approach for data collection. The content and visual analysis in this study provided the two sides of the analytic coin: the written and the visual. I am particularly interested in the narrative comments offered by the prospective brides, e.g., what they …

Executive compensation design involving equity shares has been widely used in Europe, the United States and other developed countries where the capital markets are relatively mature. In China, due to the differences in industries, ownership structure, stages of enterprise development, constraints faced by the firms, the executive compensation design using equity shares tends to vary accordingly. For the state-owned companies, the situations are more complex than others. This complexity has not been a focus of the past literature, particularly on the compensation contract design and its subsequent implementation. Based on Coase contract theorem, agency theory and human capital theory, I …

Research examining the long-term impacts of federal interventions under the Civil Rights of Institutionalized Persons Act on correctional institutions has been scant. The result has been a failure to understand the sustainability of reforms aimed at protecting the civil rights of confined persons. This dissertation examined the long-term reforms at the Arizona Department of Juvenile Corrections following a consent decree with the U.S. Department of Justice from 2004 to 2007. Interviews were conducted with current and former ADJC employees, juvenile justice advocates across Arizona, and county court representatives to determine how each of these groups perceived the status of the …

The marimba has garnered increased attention in percussion performance over the past thirty years. Literature for beginners through professionals in a multitude of styles have been written. With the ever-growing number of marimbists since the 1980's there has been a high demand for new works. Numerous pieces were created through commissions: composers contracted to write music by individuals, institutions, and consortia. Three primary types of marimba solo music were written: unaccompanied solos, concerti, and marimba solos with electronic accompaniment. Since electronic music is relatively new in marimba performance, there is very little information published regarding this topic. Only a handful …
