This thesis (written in Spanish) presents the analysis, design and implementation of a four-quadrant power supply with high-frequency isolation, which is expected to be used to feed the low-energy correction magnet of a particle accelerator. In particle accelerator applications the magnetic field during beam acceleration may be either positive or negative, and true bipolar power converters are needed. The selected bipolar topology consists of a bidirectional three-phase to single-phase reduced matrix converter (RMC) with power factor correction and a bidirectional active rectifier. Main featur...

The book aims to quantify and analyze how two water scarce but ideologically different Middle Eastern political economies, Saudi Arabia and Syria, addressed water sector investment between 1980 and 2000. The study examines how narrow-coalitions of decision-makers obsessed by impossible-to-achieve food self-sufficiency goals, lacking environmental consideration and safe political processes contributed to massively waste scarce resources and unsustainable water policies. The book shows that of Saudi Arabia’s US$1,034 billion in oil revenues (1974-2001), 48% was spent on security, plus 10% on th...

This book explores the challenges of cross-cultural translation of American literary works into Arabic which, I argue, have prevented many nineteenth-century literary works from being translated into Arabic. I have used the Arabic translations of Harriet Beecher Stowe‘s Uncle Tom’s Cabin and an abridged English text accompanying one of the translations as a case study. Since most of the Arabic translations of English and especially American literary works are merely linguistic oriented ones, I reinforce the importance of adopting a period-specific cultural-oriented approach that maintains the ...

This study examines the role of occupational status in the racialization of Indian physicians in Southern California. Since the liberalization of U.S. immigration policy in 1965, the number of first and second-generation Indian doctors in the U.S. has grown to nearly seven percent of the nation's physician workforce; however, Indians constitute less than one percent of the total U.S. population. Overrepresented in one of America's most prestigious professions, Indians are more visible in U.S. medicine than in the U.S. at large. Previous scholarship in immigration research, Asian American St...

The purpose of this study was to investigate the potential for increasing informal music-making in elementary school culture, and create a model of such music-making. Precedence for this model can be found in the literature of ethnomusicology, educational psychology and learning theory, multicultural music education, and cultural anthropology. Literature from four distinct traditions and contexts of music-making in integrative sociocultural contexts—sub-Saharan African ngoma, and Community Music as manifested in New Orleans second lines, old-time music and dance, and summer camp music-making—w...

Adaptive optics (AO) corrects distortions created by atmospheric turbulence and delivers diffraction-limited images on ground-based telescopes. The vastly improved spatial resolution and sensitivity has been utilized for studying everything from the magnetic fields of sunspots upto the internal dynamics of high-redshift galaxies. This thesis about AO science from small and large telescopes is divided into two parts: Robo-AO and magnetar kinematics. In the first part, I discuss the construction and performance of the world’s first fully autonomous visible light AO system, Robo-AO, at the Pal...

The status of emergency and disaster management (EDM) as an academic and professional discipline remains one of the field’s lingering, unresolved questions. A majority of the literature appears to support the claim that emergency management either is, or is in the process of becoming, a recognized academic and professional discipline. The claim’s key belief is that the field possesses a unique body of knowledge, an essential conceptual requirement for disciplinary status. This thesis examines the concept of professional/academic disciplines, as it relates to bodies of knowledge, and more speci...

A diagnosis of cancer brings many changes to individuals’ lives, thus becoming part of their identity. Individuals who have cancer typically struggle when adjusting and accepting these changes (Blennerhassett, 2008; Yang, Staps, & Hijmans, 2010; Allen, Savadatti, & Levy, 2009; Lindwall & Bergbom, 2009; Lewis, 2008; Welsh & Guy, 2009; Frith, Harcourt, & Fussell, 2007; Hilton, Hunt, Emslie, Salinas, & Ziebland 2008). Furthermore, medical doctors place more emphasis on the symptoms and side effects individuals undergo rather than the person’s experience of the symptoms and side effects (Frank, 19...

According to the CDC (2005), suicide claims approximately 30,000 lives each year in the United States. The law enforcement profession is a dangerous profession that oftentimes dramatically influences an officer’s perceptions of incidents often related to the repeated exposure to trauma. The intention of this research project was to explore the lived understanding of police officers regarding their acuity with respect to the subject of officer suicides. A qualitative phenomenological research was conducted, consisting of nine demographic and nine open-ended interview questions. Data were au...

In this dissertation, I have presented a comprehensive research on Bitcoin. Bitcoin was introduced in 2009. This is a decentralized digital currency and works like cash, but they are mined like gold (Volastro, CNBC Explains: How to mine bitcoins on your own, 2014). In this thesis, I will explain that how this currency works and how users can mine Bitcoins. Bitcoins mining is a very hard process, it is almost impossible to create Bitcoins on simple computer. You need specialist hardware to generate Bitcoins. Pool mining is quite popular these days, as numbers of people are taking interest in ma...
