Description
Libby Larsen is one of the most performed and acclaimed composers today. She is a spirited, compelling, and sensitive composer whose music enhances the poetry of America's most prominent authors. Notable among her works are song cycles for soprano based on the poetry of female writers, among them novelist and poet Willa Cather (1873-1947). Larsen has produced two song cycles on works from Cather's substantial output of fiction: one based on Cather's short story, "Eric Hermannson's Soul," titled Margaret Songs: Three Songs from Willa Cather (1996); and later, My Antonia (2000), based on Cather's novel of the same title. In Margaret Songs, Cather's poetry and short stories--specifically the character of Margaret Elliot--combine with Larsen's unique compositional style to create a surprising collaboration. This study explores how Larsen in these songs delves into the emotional and psychological depths of Margaret's character, not fully formed by Cather. It is only through Larsen's music and Cather's poetry that Margaret's journey through self-discovery and love become fully realized. This song cycle is a glimpse through the eyes of two prominent female artists on the societal pressures placed upon Margaret's character, many of which still resonate with women in today's culture. This study examines the work Margaret Songs by discussing Willa Cather, her musical influences, and the conditions surrounding the writing of "Eric Hermannson's Soul." It looks also into Cather's influence on Libby Larsen and the commission leading to Margaret Songs. Finally, a description of the musical, dramatic, and textual content of the songs completes this interpretation of the interactions of Willa Cather, Libby Larsen, and the character of Margaret Elliot.

Description
ABSTRACT An Ensemble Monte Carlo (EMC) computer code has been developed to simulate, semi-classically, spin-dependent electron transport in quasi two-dimensional (2D) III-V semiconductors. The code accounts for both three-dimensional (3D) and quasi-2D transport, utilizing either 3D or 2D scattering mechanisms, as appropriate. Phonon, alloy, interface roughness, and impurity scattering mechanisms are included, accounting for the Pauli Exclusion Principle via a rejection algorithm. The 2D carrier states are calculated via a self-consistent 1D Schrödinger-3D-Poisson solution in which the charge distribution of the 2D carriers in the quantization direction is taken as the spatial distribution of the squared envelope functions within the Hartree approximation. The wavefunctions, subband energies, and 2D scattering rates are updated periodically by solving a series of 1D Schrödinger wave equations (SWE) over the real-space domain of the device at fixed time intervals. The electrostatic potential is updated by periodically solving the 3D Poisson equation. Spin-polarized transport is modeled via a spin density-matrix formalism that accounts for D'yakanov-Perel (DP) scattering. Also, the code allows for the easy inclusion of additional scattering mechanisms and structural modifications to devices. As an application of the simulator, the current voltage characteristics of an InGaAs/InAlAs HEMT are simulated, corresponding to nanoscale III-V HEMTs currently being fabricated by Intel Corporation. The comparative effects of various scattering parameters, material properties and structural attributes are investigated and compared with experiments where reasonable agreement is obtained. The spatial evolution of spin-polarized carriers in prototypical Spin Field Effect Transistor (SpinFET) devices is then simulated. Studies of the spin coherence times in quasi-2D structures is first investigated and compared to experimental results. It is found that the simulated spin coherence times for GaAs structures are in reasonable agreement with experiment. The SpinFET structure studied is a scaled-down version of the InGaAs/InAlAs HEMT discussed in this work, in which spin-polarized carriers are injected at the source, and the coherence length is studied as a function of gate voltage via the Rashba effect.

Description
The legacy of the great double bassist and pedagogue Joseph Prunner (1886-1969) includes his scale and arpeggio exercise book, Progressive Studies for the Double Bass, composed in 1955. Progressive Studies was originally written for Prunner's students at the Bucharest Conservatoire and was not intended for a wide publication. In the work Prunner presents major and harmonic and melodic minor scales that are performed in one octave and then extended diatonically through all their modes, progressing through this pattern for three octaves, followed by a series of arpeggio exercises. These exercises are based on a modernized fingering system and are offered in the traditional positions and in what Prunner called "Fixed-Position" scales. A series of chromatic scale exercises are also included that follow the template of the major and minor scales. The study at hand is a revision and expansion of Prunner's work. The edition presented here intends to preserve the information that Prunner provided, fix the errors made in editing, and expand the study greatly by increasing the range of the exercises, providing more arpeggio exercises, creating melodic and harmonic minor "Fixed-Position" scales and arpeggio exercises, and including the study of double-stops. In support of the revised and updated version of Progressive Studies, this study includes a biography of Joseph Prunner and a summary of the importance of the type of scale and arpeggio practice the collection of exercises supports. An explanation of the revisions made to Prunner's work and recommendations for using the exercises also precede the new edition.

Description
New works for the bass clarinet as a solo instrument are uncommon. In the interest of expanding the repertoire of the bass clarinet, three new works for bass clarinet were commissioned from three different composers, all with different instrumentations. The resulting works are Industrial Strength for bass clarinet and piano by Kenji Bunch; Dark Embers for two bass clarinets by Theresa Martin; and Shovelhead for bass clarinet and interactive electronics by Steven Snowden. Although all three works feature the bass clarinet, they are all very different and pose unique challenges to the performer. To accompany these pieces, and as an aid to future performers, a performance practice guide has been included with recommendations for individuals who wish to perform these works. Included in the guide are recommended fingerings, practice techniques, and possible adjustments to the bass clarinet parts designed in collaboration with the composers that make the works more technically accessible. Accompanying this guide are full scores of all three works, a recording of them performed by the author, and a chart that contains recommended altissimo fingerings.

Description
This paper is the writing component of a project the author under took to create an entertaining program for a chamber ensemble. It discusses ways for chamber ensembles to create entertaining concert programs for today's audiences. Information was gathered by analyzing four interesting and successful groups--The Canadian Brass, Mnozil Brass, Les Trompettes de Lyon, and The Blue Man Group--and identifying common traits. These traits help facilitate the ultimate goal of making connections with audiences and include originality, comedy, choreography, memorization, continuous presentation, musical appeal, high quality presentations, and the proper personnel. These attributes were then implemented into the author's experimental group, the Omni Brass Ensemble, for testing with live audiences. Materials were used from published interviews, articles, newspapers, ensemble websites, and recordings of their performances. From the author's performances with the Omni Brass Ensemble, indications are that these findings work with live audiences.

Description
John Harbison is one of the most prominent composers of the twentieth and twenty-first centuries. He has made major contributions in all areas of classical music, including operas, symphonies, chamber music, choral works, and vocal pieces.Among his vast output is 'Four Songs of Solitude,' his only composition (to date) for solo violin. Though the piece is beautiful and reflective in nature, its inherent technical and musical difficulties present challenges to violinists preparing the piece. There is no published edition of 'Four Songs of Solitude' that includes bowings and fingerings, and violinists used to practicing and performing the études and repertoire of the eighteenth and nineteenth centuries may have difficulty determining how to successfully navigate the music. This paper examines the piece in detail, providing an analytic description of the music and suggestions for practice. An interview with the composer yielded many insights into the structural and harmonic events of the songs, and the composer's interpretive suggestions are given alongside technical suggestions by the author. The solo violin has a centuries-long legacy, and some of the most performed repertoire exists in the medium. 'Four Songs of Solitude' is a demanding set of pieces that stands out in late twentieth-century violin music. Providing information about the piece directly from the composer and suggestions for practice and performance increases the accessibility of the work for violinists seeking to bring it to the concert stage.

Description
The ability of musicians to perform well in multiple musical styles is increasingly common and necessary. This paper profiles two trombonists who have gone well beyond the ability to function in multiple genres, and are instead considered significant artists. Tony Baker and Alex Iles were chosen to be profiled for this project because both have achieved recognition as solo artists in the genres of classical music and jazz and have performed on international stages as soloists. They also have significant ensemble experience in both classical and jazz settings and are active teachers as well. Both hold-high profile positions that have helped grow their reputations as performers: Mr. Baker as a professor at one of the largest music schools in the United States, the University of North Texas, and Mr. Iles as a highly in-demand freelance musician in Los Angeles. This paper presents interviews with both trombonists that investigate their development as musicians and soloists in both classical music and jazz. They are asked to describe the benefits and challenges of performing at a high level in both styles, and how these have affected their musical voices. Common traits found in their responses are examined, and recommendations are created for musicians seeking stylistic versatility.

Description
An investigation is undertaken of a prototype building-integrated solar photovoltaic-powered thermal storage system and air conditioning unit. The study verifies previous thermodynamic and economic conclusions and provides a more thorough analysis. A parameterized model was created for optimization of the system under various conditions. The model was used to evaluate energy and cost savings to determine viability of the system in several circumstances, such as a residence in Phoenix with typical cooling demand. The proposed design involves a modified chest freezer as a thermal storage tank with coils acting as the evaporator for the refrigeration cycle. Surrounding the coils, the tank contains small containers of water for high-density energy storage submerged in a low freezing-point solution of propylene glycol. The cooling power of excess photovoltaic and off-peak grid power that is generated by the air conditioning compressor is stored in the thermal storage tank by freezing the pure water. It is extracted by pumping the glycol across the ice containers and into an air handler to cool the building. Featured results of the modeling include the determination of an optimized system for a super-peak rate plan, grid-connected Phoenix house that has a 4-ton cooling load and requires a corresponding new air conditioner at 4.5 kW of power draw. Optimized for the highest payback over a ten year period, the system should consist of a thermal storage tank containing 454 liters (120 gallons) of water, a 3-ton rated air conditioning unit, requiring 2.7 kW, which is smaller than conventionally needed, and no solar photovoltaic array. The monthly summer savings would be $45.The upfront cost would be $5489, compared to a conventional system upfront cost of $5400, for a payback period of 0.33 years. Over ten years, this system will provide $2600 of savings. To optimize the system for the highest savings over a twenty year period, a thermal storage tank containing 272 liters (72 gallons) of water, a 40-m2 photovoltaic array with 15% efficiency, and a 3.5-ton, 3.1-kW rated air conditioning unit should be installed for an upfront cost of $19,900. This would provide monthly summer savings of $225 and 1062 kWh grid electricity, with a payback period of only 11 years and a total cost savings of $12,300 over twenty years. In comparison, a system with the same size photovoltaic array but without storage would result in a payback period of 16 years. Results are also determined for other cooling requirements and installation sizes, such that the viability of this type of system in different conditions can be discussed. The use of this model for determining the optimized system configuration given different constraints is also described.

Description
The project described here is a solar powered intrusion detection system consisting of three modules: a battery recharging circuit, a laser emitter and photodetector pair, and a Wi- Fi connectivity board. Over the preceding seven months, great care has been taken for the design and construction of this system. The first three months were spent researching and selecting suitable IC's and external components (e.g. solar panel, batteries, etc.). Then, the next couple of months were spent ordering specific materials and equipment for the construction of our prototype. Finally, the last two months were used to build a working prototype, with a substantial amount of time used for perfecting our system's packaging and operation. This report will consist of a detailed discussion of our team's research, design activities, prototype implementation, final budget, and final schedule. Technical discussion of the concepts behind our design will assist with understanding the design activities and prototype implementation sections that will follow. Due to the generous funding of the group from the Barrett Honors College, our overall budget available for the project was $1600. Of that amount, only $334.51 was spent on the actual system components, with $829.42 being spent on the equipment and materials needed for the testing and construction of the prototype. As far as the schedule goes, we are essentially done with the project. The only tasks left to finish are a successful defense of the project at the oral presentation on Friday, 29 March 2013, followed by a successful demo on 26 April 2013.

Description
ABSTRACT The Orpheus Male Chorus of Phoenix occupies and maintains an historical place in the musical and civic history of the City of Phoenix and the State of Arizona. Organized in November, 1929, the Orpheus Male Chorus of Phoenix (OMC) is the only performing arts organization in Phoenix that can claim eighty-one years of continuous performance. The chorus gained popularity locally, nationally, and internationally in its first five decades. The breadth of the chorus's recognition began to decline in the latter part of the 20th century, but the chorus still retains a loyal following of audience members. This study focuses on the first fifty years of the OMC, especially the period from 1946 to 1979, the years the chorus was under the direction of Ralph Hess. Through his leadership the group's popularity and recognition reached a peak, thanks largely to his emphasis on civic responsibility, ties to service organizations, and musical ability and showmanship. No scholarly publications exist regarding this organization. Several boxes of memorabilia housed in the Arizona Historical Society Museum in Tempe, Arizona, serve as the primary source of material for this study. Concert programs supply information about concert repertoire, advertising, and chorus history. Newspaper articles from local and international press offer reviews, announcements, and media perceptions of the chorus. Information illustrating the abundant civic engagement of the OMC appears in proclamations and awards from local, state, national, and international personalities. This objective information helps propel the story forward, as do the personal letters and stories contained within the collection. Because many documents from the latter part of the 1970s are missing, the primary source information becomes more anecdotal and subjective. This study illustrates some of the ways in which the OMC went beyond mere survival to occupy a significant place in the musical life of Phoenix. Engagement in civic and social functions and support for non-profit organizations established the chorus as more than just a musical ensemble. Their pursuit under Hess of "Cultural Citizenship" earned them international recognition as civic leaders and ambassadors of goodwill.
