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...

Driven to improve their competitive advantages, manufacturers are looking to electronic supply chain collaboration (ESCC). The benefits of ESCC have long been described in the literature, but only recently, after considerable advances in the capability of information technology, have these benefits been verified by empirical studies. The high cost of ESCC has limited its early application to larger companies. Although interest in ESCC is high in business and information systems circles, the large group of small manufacturers has received meager attention. Theory suggests, however, that ESCC be...

Cross Language Text Retrieval (CLTR) has been defined as the retrieval of documents in a language different from that of the original query. To make this possible some kind of mechanism has to be applied in order to translate the information contained in the source sentence. Many different approaches have been carried out with the purpose of transferring the information from the source language query to the target language one. Though all these methods deal with a way of translating as much information as possible from the source query, little research has been conducted in relation to the fie...

The complementary and alternative (CAM) health movement is a burgeoning phenomenon in contemporary American culture. Types of healing alternatives to conventional medicine became increasingly popular in the latter quarter of the 20th century and some physicians, hospitals, and government entities have began to acknowledge the fields with validity. While alternatives to conventional medicine have always existed, contemporary interest in CAM may trigger an interest in unconventional forms of energy healing such as Reiki. The purpose of this research study was to investigate if Reiki could red...

Various business models have been presented each reflecting their strengths and weaknesses. The first model demonstrates consumer purchase behavior. The second model demonstrates marketing strategies. The third model demonstrates the use of various advertising vehicles and the last model demonstrates the human aspect that combines salesmanship and leadership with ethical business codes of conduct. This researcher found a multitude of articles, books, journals, and websites on each topic and recognized the need for these models to merge. Based on the readings, you will observe the pros and ...

Scope of Study: The author of this dissertation surveyed psychologists in the United States to determine the forms of technology that are currently being utilized in their practice. Through the use of a survey, the study intends to show that technological applications are currently being underutilized in the counseling profession and there exists great potential for marketing new technology to counselors. The new technological ideas that were explored in the study included the use of computer aided diagnostic techniques, video-counseling and the use of a voice stress analyzer.Findings and Co...

The study explored the perception of executive coaching among the chief executive officers (CEOs) of America's largest 500 companies as shown on Fortune magazine list of April 15, 2002. This study utilized an instrument of 12 questions. The questionnaire was sent to the CEOs of the top 500 American companies. A cover letter and a self-addressed, postage-paid envelope were provided. Attribute responses were coded and analyzed using several descriptive statistical tools. Out of the 500 targeted CEOs, 143 participated in this study. Seventy-six percent of the respondents demonstrated a good und...

Is there a qualitative difference between memory functions in adults and children? Given the relevance of memory processes for virtually every aspect of everyday life and the complex interactions between memory development and general cognitive abilities, surprisingly little is known about memory abilities in childhood. In four experiments with children aged 6-12 years and young adults, the developmental trajectories of two separate mechanisms underlying recognition memory - familiarity and recollection - were examined using event-related potentials (ERPs). Developmental changes were evident ...

The present study aims to illuminate the way participant learning in adventure experiences intersects with broader social, cultural and institutional contexts, and was guided by the following questions: How is participant experience constructed in a facilitated, small group adventure setting? How is the construction of the adventure experience related to the intentions and orchestrations of the trainer? How is the construction of the adventure experience related to the institutional and social context in which it occurs? This study used grounded theory methodology (Strauss & Corbin, 1998) and...
