Tommy Smith is considered by many to be one of the greatest jazz saxophonists not only in Scotland, but world-wide. Celebrated for his virtuosic performance skills, tremendous compositions, and prized albums in the jazz idiom, Smith has also had great success as a composer and performer of the classical genre. Fusing the styles of jazz and classical, he composed and recorded two sonatas, entitled, Sonata No. 1 - Hall of Mirrors and Sonata No 2. - Dreaming with Open Eyes, on his 1998 album, Gymnopédie: The Classical Side of Tommy Smith. Unique pieces, they are not considered standard repertoire in the classical saxophone world, however, they are welcomed, substantial works for either the soprano or tenor saxophone and piano. Composed in a classical style and performed with jazz inflections and improvisation, these sonatas are challenging pieces to learn and execute at a high level. For many classical saxophonists, improvising a cadenza or utilizing standard jazz performance techniques could dissuade them from performing these terrific, distinctive works. This study is intended to aid in the learning and presentation of these two pieces, and includes transcriptions from Tommy Smith's album, errata, and performance analyses for each sonata.

Este modelo de negocio consiste en ofrecer audios informativos sobre destinos turísticos vía redes sociales y website. El público objetivo son los turistas en centros turísticos en las regiones de Cusco, Arequipa y Lima (destinos inicialmente ofrecidos) que tengan entre 18 y 44 años. A continuación, se detallará las necesidades identificadas, la solución planteada, los experimentos realizados y el plan de negocios. Con relación a la necesidad, se identificó que los turistas que visitaban los diferentes destinos no estaban completamente satisfechos con las visitas guiadas en grupo, ya sea por los estrictos horarios, la cantidad de personas, entre otros. Así, se halló la oportunidad para plantear un modelo de negocios que les permita personalizar su experiencia y puedan decidir sobre diversos factores como los tiempos, los destinos a visitar, la cantidad de personas con las que quieren ir, etc. Para plantear el modelo de negocio de una manera simplificada, se utilizó la herramienta Business Model Canvas. Con el fin de validar la solución, el modelo de negocio y el interés de compra de los usuarios; se desarrolló una serie de experimentos desde entrevistas hasta campañas para incentivar la demanda. El plan de negocios de Turistea se basó en identificar la necesidad de los usuarios, plantear y validar la solución y el modelo de negocio, y aplicar la metodología Concierge para validar el interés de compra y viabilidad del proyecto. / The present research project has the purpose of developing a business plan for a service of audio guides called Turistea. This business model consists in offering informative audios about tourist attractions via social networks and a company website. The target audience of the project are tourists that are visiting Cusco, Arequipa, and/or Lima (Turistea’s three initial destinations); between the ages 18 and 44. In the next paragraphs the identified need, the proposed solution, the experiments performed, and the business plan will be further detailed. The identified need was that the tourists were not completely satisfied with group guided tours, due to the tight schedules, the amount of people in the group, etc. Thus, the opportunity to propose a business model that allows the users to further personalize their experience and be able to decide on various factors such as times and destinations was found. In order to pose the business model in a simplified way, the Business Model Canvas tool was used to identify the key points of the company. To validate the proposed solution, the business model, and the user’s purchase interest; a series of experiments were developed, ranging from interviews to discount campaigns to boost the demand. Turistea’s business plan was based on identifying the user’s needs, proposing, and validating the solution and business model, and applying the Concierge methodology to validate the purchase interest and project’s viability. / Trabajo de investigación

Indiana University-Purdue University Indianapolis (IUPUI) / In the first part of this thesis, we investigate the propagation of quantum fluctuations in a nonlinear interferometer comprising under conditions of harmonic generation by computer simulations. This investigation assumes idealized conditions such as lossless and uniform nonlinear media, an ideal cavity and ideal photodetectors. After linearizing wave equations for harmonic generation with a coherent state input, we obtain equations for one dimensional spatial propagation of the mean field and quantum fluctuations for initial conditions set by arbitrary interferometer phase. We discover that fluctuations are de-squeezed in the X and Y quadratures as the interferometer phase is tuned. However, we discover that there is are quadratures P-Q obtained by rotating the X-Y quadratures for which squeezing is improved by factors of 10^9. We present a practical idea to implement rotation of X quadrature fluctuations to the Q quadrature by using an ideal empty optical cavity. Signal-to-Noise ratio of the nonlinear interferometer was calculated and compared with that of a linear interferometer with coherent state input. We calculated a maximum performance improvement of a factor of 60 for a normalized propagation length ζ0 = 3 under ideal conditions. In the second part of this thesis, we investigate experimentalarrangements to transfer atomic coherence from light to cesium atoms. We discuss the experimental arrangement to generate coherence under conditions of electromagnetically induced transparency (EIT). We measure a continuous wave EIT width of 7.18 MHz and present results for pulsed arrangements.

This investigation was based on a production performed by the Irving, Texas, Community Theatre in March, 1978, directed by the author of this thesis. The paper concerned the problems of producing a play under adverse conditions, such as lack of money, inadequate technical equipment, and a small stage. Chapter I included an investigation of the reviews of the original production in order to establish criteria by which to judge the Irving production. Chapters II and III dealth with varied technical aspects and their application under the adverse conditions. Examples of the technical factors were included in Chapter IV, with a scene synopsis. Chapter V contained a primarily favorable analysis based on the critic's and the audience's judgments, indicating most production elements to be successful.

Les guides d'ondes optiques sont utilisés dans plusieurs dispositifs de télécommunications pour le transport d'informations numériques. Nous les retrouvons aussi dans les équipements médicaux ou d'ingénierie, comme par exemple les coupleurs, les interféromètres optiques, les convertisseurs de polarisation, etc. Le transport des informations dans ces structures demeure une question capitale et donc les méthodes utilisées doivent être capables de véhiculer ces informations avec un minimum de perte. Dans cette thèse, nous présentons une méthode numérique d'approximation qui permet la simulation du transport des ondes dans une direction choisie avec le maximum de précision et à un coût abordable. Cette méthode est basée sur une approximation au sens de Padé d'opérateurs pseudo-différentiels associés à la fonction algébrique y/1 — x . Essentiellement, nous approchons une équation différentielle ordinaire (EDO) d'ordre 2 par une EDO d'ordre 1 dont les solutions ont la même phase que celle des solutions de l'EDO d'ordre 2 qui se propagent dans la direction choisie. Nous avons évalué les capacités de cette méthode sur de nombreux problèmes bidimensionnels et tridimensionnels. Elle s'est révélée à la fois robuste et précise

The choral music of Hyo-won Woo, the composer of Oh! KOREA, is being widely performed by universities and professional choruses in Korea, as well as throughout the world. The work exhibits Woo's remarkable compositional style, which displays traditional Korean musical influences. Hyo-Won Woo's Oh! KOREA consisting of four movements, is for chorus, two pianos, and both Eastern and Western percussion instruments. Woo's Oh! KOREA employs an excellent introduction to the Korean choral repertoire for Western audiences, rooted in traditional Korean folk tunes. As today's choral conductors, singers, and audience cannot fully appreciate the value of this traditional Korean work and will likely not understand its intended context, it is therefore necessary to provide an in-depth investigation of this work for any conductor considering a performance of this piece. This study includes influences of traditional Korean elements within Oh! KOREA and rehearsal and performance consideration for Western choir directors.

The goal of this research was to investigate teachers' perceptions of professional discretion and satisfaction related to internal and external factors of curriculum control. Results of the study were intended to provide data to policy makers and school district administrators that could be used in the development and implementation of the curriculum reform process. Middle and high school teachers in a large central Florida school district completed the survey. The survey's six constructs were 1. Influence of Teacher Beliefs 2. Perceptions of Success and Satisfaction 3. Influence of Tests and Curriculum Guides 4. Teacher Control of Pedagogy 5. Leadership 6. Maintaining High Standards The research questions focused on determining the difference in perspectives due to years of teaching experience, level of teaching (middle or high school), and curriculum control category (high, medium, or low). The results revealed there was not significant disagreement among teacher perceptions based on years of teaching experience. However, results indicated significant differences in perceptions based on level of teaching and curriculum control category in regard to the six survey constructs. The construct of leadership revealed significant differences between both levels of teaching and curriculum control categories. Overall, the results indicated a significant relationship among curriculum control policies and effects on teachers' perceptions of professional discretion and satisfaction. The literature on curriculum reform efforts since the 1980s, specifically in the areas of curriculum standards, textbook adoption policies, testing policies and leadership practices, framed the study. The literature review focused on existing research issues within the six constructs and the research questions. The information gained from this study may be used to inform policies, improve teachers' working conditions, and promote teacher and leadership effectiveness. Recommendations for practice were addressed in terms of what policy makers, school district administrators, and individual classroom teachers can and should do to implement and support meaningful curriculum reform. The researcher emphasized that recognizing the professional expertise and knowing the perspective of teachers are key to the development and implementation of an effective curriculum reform process.

The use of ultracold neutrons (UCN) to study fundamental parameters such as the neutron lifetime and decay correlations in polarized neutron beta decay are poised to make significant contributions to our understand of the Standard Model and its extensions. To this end, the UCNA experiment is pursuing a precision measurement (0.2%) of the angular correlation between the neutron spin and the direction of emission of the electron in polarized neutron decay (the ``A'' asymmetry). The UCNA experiment makes use of the spallation-driven solid deuterium (SD2) UCN source at the Los Alamos Neutron Science Center (LANSCE). The UCN leave the source and are 100% polarized by passing through a strong magnetic field before their decay is observed by a very sensitive electron spectrometer. UCN guides facilitate the transfer of UCN from the source to the spectrometer. Common guide materials include stainless steel, copper, aluminum, and quartz. Often a thin film is applied to these components to increase their ability to transport/bottle and preserve the polarization of UCN. In the region of the SD2 UCN source, nickel-58 films are applied, whereas once the UCN are polarized, diamond-like carbon (DLC) films are employed. This dissertation covers the application, process developments, and characterization of these coatings. In addition a study concerning the surface finish resulting from the mechanical polishing and electropolishing of the guides that make up the UCNA beamline is presented. / Ph. D.
