Space and Spectrum Engineered High Frequency Components and Circuits
With the increasing demand on wireless and portable devices, the radio frequency front end blocks are required to feature properties such as wideband, high frequency, multiple operating frequencies, low cost and compact size. However, the current radio frequency system blocks are designed by combining several individual frequency band blocks into one functional block, which increase the cost and size of devices. To address these issues, it is important to develop novel approaches to further advance the current design methodologies in both space and spectrum domains. In recent years, the concept of artificial materials has been proposed and studied intensively in RF/Microwave, Terahertz, and optical frequency range. It is a combination of conventional materials such as air, wood, metal and plastic. It can achieve the material properties that have not been found in nature. Therefore, the artificial material (i.e. meta-materials) provides design freedoms to control both the spectrum performance and geometrical structures of radio frequency front end blocks and other high frequency systems. In this dissertation, several artificial materials are proposed and designed by different methods, and their applications to different high frequency components and circuits are studied. First, quasi-conformal mapping (QCM) method is applied to design plasmonic wave-adapters and couplers …

Design of a Wideband Class J Power Amplifier
A conventional RF power amplifier will convert the low powered radio frequency signals into high powered signals. Along with the expected ability to increase the communication distance, data transfer rates, RF power amplifiers also have many applications which include military radar system, whether forecasting, etc. The main objective of any power amplifier research is to increase the efficiency while maintaining linearity and broadening the frequency of operation. The main motivation for the renewed interest in PA technology comes from the technical challenges and the economics of modern digital communication systems. Modern communications require high linear power amplifiers and in order to reduce the complete system cost, it is necessary to have a single broadband power amplifier, which can amplify multiple carriers. The improvement in the efficiency of the power amplifier increases the battery life and also reduces the cooling requirements for the same output power. In this thesis, I aim to design and build a wideband class J power amplifier suitable for modern communications. For wideband operation of the GaN technology PA, a bandwidth extension design method is studied and implemented. The simulation results are proved to have a good argument with the theoretical calculations.

Low Leakage Asymmetric Stacked Sram Cell
Memory is an important part of any digital processing system. On-chip SRAM can be found in various levels of the memory hierarchy in a processor and occupies a considerable area of the chip. Leakage is one of the challenges which shrinking of technology has introduced and the leakage of SRAM constitutes a substantial part of the total leakage power of the chip due to its large area and the fact that many of the cells are idle without any access. In this thesis, we introduce asymmetric SRAM cells using stacked transistors which reduce the leakage up to 26% while increasing the delay of the cell by only 1.2% while reducing the read noise margin of the cell by only 15.7%. We also investigate an asymmetric cell configuration in which increases the delay by 33% while reduces the leakage up to 30% and reducing the read noise margin by only 1.2% compared to a regular SRAM cell.

Student Perceptions of Teacher Credibility: A Predictor of Academic Success
While the idea of source or teacher credibility dates back to the Greek philosopher, Aristotle, research to connect this perceived credibility with individual affective and cognitive growth is a more recent phenomenon. In 2009, a credibility learning model connecting perceived credibility to cognitive learning with university-aged subjects was established. In contrast, this research project focused on determining a link between K-12 students' perception of teacher credibility, as determined by a student survey, to cognitive academic achievement as rated by a standardized test, the State of Texas Assessment of Academic Readiness (STAAR). The survey data were obtained through a pre-existing campus climate survey that was created to assist campus and district administrators in determining campus needs and developing a campus improvement plan. The assessment data were obtained through the Texas Education Agency database. The data were analyzed using quantitative research methods, including traditional univariate and multivariate statistical techniques such as principal component analysis, chi-square tests for independence, and binomial logistic regression. The findings of the study revealed no link between the survey instrument used and student academic achievement on the STAAR reading and mathematics assessment. The survey used did not align with the review of literature regarding student's perception of teacher …

"Where Do We Go From Here?" Teaching a Generation of Nclb Students in College Classrooms
Since the passing of No Child Left Behind Act in 2001, the United States' secondary education system has undergone significant changes. In this study, I discuss the ways in which the law has encouraged the normalization of standardized testing and aim to answer two primary research questions. RQ1: What do college students and their instructors identify as the key challenges that arise as students educated under NCLB begin college coursework, and how does each group address these challenges? RQ2: What strategies do the actors and spect-actors in a Forum Theatre production arrive at for addressing the challenges faced by college instructors and their students who have completed their secondary education under No Child Left Behind? To answer the initial research question, I conducted focus group interviews with instructors and students at the University of North Texas to understand the challenges each faces in the classroom. To answer the second research question, I compiled narratives from the focus group interviews along with other materials into a performance script that concluded with scenarios based in Augusto Boal's Forum Theatre techniques. In live performance events audience members rehearsed strategies for addressing the challenges that instructors and students face in classrooms through performance. Following …

Connecting the Circuit: Analyzing Jurors' Cognitive Gaps and Damage Awards in Patent Infringement Trials
Patent litigation is notorious for the technicality of evidence and the rhetoric of experts. Citizens selected to serve on the jury have no specialized training and have rarely been exposed to the technology or the patent process. This study provides insight into the field of jury decision-making in complex patent cases by analyzing the cognitive gaps and the tactics used by jurors to minimize them. Additionally, the study examines the justifications for the damage awards jurors provide. This analysis focused on jurors engaged in mock trial patent deliberations. The story model and sensemaking theory serve as the theoretical framework of this research and provide a structure for support and a lens for analysis. The results indicate that jurors rely on three distinct and dichotomous topologies when navigating cognitive gaps. Searching for answers either individually or as a group, relying on lists or stories, and turning to facts or emotions, jurors navigate through their uncertainty. Through the line-by-line analysis of mock jury transcriptions, three continuums regarding damage justifications emerged. Jury members found themselves navigating uncertainty versus certainty, rationality versus irrationality, and facts versus emotions. The theoretical implications broaden the story model to include cognitive gaps in all phases and increase the …

Re-Branding Palliative Care: Assessing Effects of a Name Change on Physician Communicative Processes During Referrals
Although provision of palliative care on the United States is growing, referrals to the service are often late or non-existent. The simultaneous care model provides a blueprint for the most progressive form of palliative care, which is palliation and disease-oriented treatments delivered concurrently. Research indicates the existence of a widespread misconception that associates palliative care with imminent death, and some organizations have chosen to re-brand their palliative care services to influence this perception. The goal of this study was to assess the effects of a name change from palliative care to supportive care on the communicative process during referrals to the service.

This Isn't About Me: Communication Privacy Management Theory and Public Confession
Individuals at the DFW Church publicly confess intensely personal information, such as drug and alcohol addiction, spousal and child abuse, stripping, and sexual abuse. Using communication privacy management theory (CPM), I examined the way individuals at the DFW Church manage their private information, how they make disclosure decisions, and how they manage boundaries around their private information. I interviewed 13 individuals who participated in public confession, and coded their responses to identify the common themes and tactics for making disclosure decisions. Through this process, I pioneer the application of CPM to examine public disclosure events, rather than dyadic or small group disclosures. I also expand our current understanding of motivations for disclosure; rather than focusing on selfish or therapeutic motivations, participants want to encourage others through their disclosure. In terms of boundary management, individuals at the DFW Church believe that God owns part, or all, of their information; thus, disclosing their pasts is "not about them." Participants construct a new identity through their testimony narrative, effectively putting the old person in the past and presenting a new, Christian identity to the church body for group approval. In this context, confessing a negative behavior becomes a way to build a positive …

Looting and Restitution During World War II: a Comparison Between the Soviet Union Trophy Commission and the Western Allies Monuments, Fine Arts, and Archives Commission
From the earliest civilizations, victorious armies would loot defeated cities or nations. the practice evolved into art theft as a symbol of power. Cultural superiority confirmed a country or empire’s regime. Throughout history, the Greeks and Romans cultivated, Napoleon Bonaparte refined, and Adolf Hitler perfected the practice of plunder. As the tides of Second World War began to shift in favor of the Allied Powers, special commissions, established to locate the Germans’ hoards of treasure, discovered Nazi art repositories filled with art objects looted from throughout Europe. the Soviet Union Trophy Commission and the Western Allies Monuments, Fine Arts, and Archives Commission competed to discover Nazi war loot. the two organizations not only approached the subject of plunder as a treasure hunt, but the ideology motivating both commissions made uncovering the depositories first, a priority. the Soviet trophy brigades’ mission was to dismantle all items of financial worth and ship them eastward to help rebuild a devastated Soviet economy. the Soviet Union wished for the re-compensation of cultural valuables destroyed by the Nazis’ purification practices regarding “inferior” Slavic art and architecture; however, the defeated German nation did not have the ability to reimburse the Soviet State. the trophy brigades implemented …

Belfast: Perspectives of a City
This thesis film is an examination of my evolving perspectives and understanding of my Irish heritage as I travel to the city of Belfast, Northern Ireland. Through the course of a year and a half, I traveled to Belfast to explore the modern state of the sectarian conflicts between the Catholic and Protestant communities. Through the use of personal reflection, historical research, interviews with local residents, and on-location experiential learning, I began to learn not only about the modern state of Belfast and its economic and social climate, but also about the complexities of personal cultural identification and the concept of “truth” and “mutual guilt” when associated with acts of violence. With the use of the short documentary as the medium of choice, I am able to relay to audiences not only my own personal reflection of identity and history, but then allow them to reflect on their own perspectives as well, helping to create sincere moments of personal thought and reflections.

Athletic Trainers and Sport Psychology: Knowledge, Experience and Attitudes
Certified athletic trainers (ATCs) play a unique role in sport environments as the primary medical staff available to athletes. Thus, ATCs are well positioned to oversee athletes’ physical and psychological well-being. Although sport psychologists (SPs) have been identified as a potential resource for ATCs, previous studies have reported a lack of collaboration between SPs and ATCs. This study aimed to (a) examine ATCs’ views regarding professional roles for both ATCs and SPs, (b) explore ATCs’ referral behaviors, (c) evaluate ATCs belief in the credibility of sport psychology across demographic (i.e., gender, age) and experiential variables (i.e., access to SPs), and (d) examine ATCs’ involvement in sport psychology. Four hundred ninety-six ATCs (265 men, 231 women) completed and returned the questionnaire. ATCs viewed assisting in the psychological recovery of athletes as the most acceptable professional role for fellow ATCs; aiding in the psychological recovery of injured athletes and teach mental skills were identified by ATCs as the most appropriate roles for SPs. In considering an athlete experiencing interpersonal difficulties (e.g., relationship problems), a mixed design ANOVA revealed a ATC sex by referral option interaction; female and male ATCs indicated they would likely refer the athlete to a counselor/therapist, followed by a …

Algorithmic Music Analysis: a Case Study of a Prelude From David Cope’s “From Darkness, Light”
The use of algorithms in compositional practice has been in use for centuries. With the advent of computers, formalized procedures have become an important part of computer music. David Cope is an American composer that has pioneered systems that make use of artificial intelligence programming techniques. In this dissertation one of David Cope’s compositions that was generated with one of his processes is examined in detail. A general timeline of algorithmic compositional practice is outlined from a historical perspective, and realized in the Common Lisp programming language as a musicological tool. David Cope’s compositional output is summarized with an explanation of what types of systems he has utilized in the analyses of other composers’ music, and the composition of his own music. Twentieth century analyses techniques are formalized within Common Lisp as algorithmic analyses tools. The tools are then combined with techniques developed within other computational music analyses tools, and applied toward the analysis of Cope’s prelude. A traditional music theory analysis of the composition is provided, and outcomes of computational analyses augment the traditional analysis. The outcome of the computational analyses, or algorithmic analyses, is represented in statistical data, and corresponding probabilities. From the resulting data sets part of …

Synthesis Strategies and a Study of Properties of Narrow and Wide Band Gap Nanowires
Various techniques to synthesize nanowires and nanotubes as a function of growth temperature and time were investigated. These include growth of nanowires by a chemical vapor deposition (CVD) system using vapor-liquid-solid (VLS) growth mechanism and electro-chemical synthesis of nanowires and nanotubes. Narrow band gap InSb Eg = 0.17 eV at room temp) nanowires were successively synthesized. Using a phase diagram, the transition of the nanowire from metallic- semiconducting- semi-metallic phase was investigated. A thermodynamic model is developed to show that the occurrence of native defects in InSb nanowires influenced by the nanowire growth kinetics and thermodynamics of defect formation. Wide band gap ZnO (Eg = 3.34 eV) and In2O3 (3.7 eV) were also synthesized. ZnO nanowires and nanotubes were successfully doped with a transition metal Fe, making it a Dilute Magnetic Semiconductor of great technological relevance. Structural and electronic characterizations of nanowires were studied for different semiconducting, metallic and semi-metallic nanowires. Electron transport measurements were used to estimate intrinsic material parameters like carrier concentration and mobility. An efficient gas sensing device using a single In2O3 nanowire was studied and which showed sensitivity to reducing gas like NH3 and oxidizing gas like O2 gas at room temperature. The efficiency of the …

Sustainable Energy Solutions for Water Purification Applications: Municipal and Industrial Case Studies
In several areas around the world, clean water is a precious asset that at anytime, and mainly due to circumstances of weather and climate, can become scarce. Mainly in the dry and remote places, people suffer with lack of water. A solution for this suffering can be a water desalination system, which makes water potable and usable for industry. That solution inherently, brings the problem of power requirement, which is sometimes arduous to accomplish in such remote areas of difficult access and long distances to overcome to build the infrastructure required to operate an electric power plant. Texas and the USA also face this scenario for many regions, for which the government has been creating some programs and driving forward incentives, looking for solutions to support water desalination. Water desalination has future applications for municipalities water-consuming or for arid and remote regions, as well as for industries that rely on heavy water usage, such as natural gas drilling operations, for which millions of gallons are trucked overland to the site and also hauled away afterwards, when the waste water produced must be treated. This thesis created the concept of autonomy for water desalination plants replacing the actual power supply from …

Socioeconomic Status and Prosperity Belief in Guatemala
A popular belief in the exploding Pentecostal movement in the global South is the idea that if an individual has enough faith, God will bless them with financial prosperity. Although historically Pentecostalism has been identified as a religion of the poor, this study examines recent arguments that the current Pentecostal movement in Guatemala is a religion of the socially mobile middle and elite classes. Data from the Pew Forum on Religious and Public Life’s 2006 survey Spirit and Power: Survey of Pentecostals in Guatemala is used to conduct a logistic regression, in order to measure the effects of socioeconomic status on adherence to prosperity belief. Results suggest that, contrary to the current literature on Guatemalan Pentecostalism, prosperity belief is not necessarily concentrated among the upwardly mobile middle and upper classes, but rather is widely diffused across social strata, and in particular, among those that have lower levels of education. These findings have implications for the study of Pentecostalism in Guatemala and in the global South in general.

Interfacial Characterization of Chemical Vapor Deposition (Cvd) Grown Graphene and Electrodeposited Bismuth on Ruthenium Surface
Graphene receives enormous attention owing to its distinctive physical and chemical prosperities. Growing and transferring graphene to different substrates have been investigated. The graphene growing on the copper substrate has an advantage of low solubility of carbon on the copper which allow us to grow mostly monolayer graphene. Graphene sheet of few centimeters can be transferred to 300nm silicon oxide and quartz crystal pre-deposited with metal like Cu and Ru. Characterization of the graphene has been done with Raman and contact angle measurement and recently quartz crystal microbalance (QCM) has been employed. The underpotential deposition (UPD) process of Bi on Ru metal surface is studied using electrochemical quartz crystal microbalance (EQCM) and XPS techniques. Both Bi UPD and Bi bulk deposition are clearly observed on Ru in 1mM Bi (NO3)3/0.5M H2SO4. Bi monolayer coverage calculated from mass (MLMass) and from charge (MLCharge) were compared with respect to the potential scanning rates, anions and ambient controls. EQCM results indicate that Bi UPD on Ru is mostly scan rate independent but exhibits interesting difference at the slower scan. Bi UPD monolayer coverage calculated from cathodic frequency change (ΔfCathodic) is significantly smaller than the monolayer coverage derived from integrated charge under the cathodic …

Krzysztof Penderecki’s Divertimento/suite for Cello Solo (1994-2013): a Stylistic Analysis and Performance Guide
Penderecki made a tremendous variety of contributions to the cello repertoire. His profound respect for tradition and for his past is deeply appreciated by both performers and audiences. In each individual composition, he explored the cello’s sonorous possibilities and created a new technical and musical palette for the instrument. He worked with legendary, world-renowned cellists who not only gave the premieres of his works but also established deep friendships with him. The Divertimento/Suite for Cello Solo (1994-2013), a compilation of miniature movements, each with its sophisticated structure, demonstrates Penderecki’s three compositional style periods. Baroque and Romantic elements in each movement are achieved within their style characteristics. Penderecki’s Divertimento/Suite for Violoncello Solo is composed of eight contrasting movements that were written during a nineteen-year period. The work is characterized by a Neo-Romantic aesthetic and utilizes the cello’s dark lyrical tones with a variety of timbre and tonal contrasts. The purpose of the present study is to create a practical performance guide to this important musical work with a detailed stylistic, textural, and motivic analysis of all eight movements. Although there are many published documents and analyses of Penderecki’s orchestral, choral, chamber and other solo pieces, the Divertimento/Suite for Cello Solo has …
