ABSTRACT This document introduces singers and voice teachers to Dr. Alfred A. Tomatis's listening training method with a particular emphasis on its relevance to singers. After presenting an overview of Tomatis's work in the field of audio-psycho-phonology (circa 1947 through the 1990s) and specific ways that aspects of his theory are relevant to singers' performance skills, this project investigates the impact of listening training on singers by examining published research. The studies described in this document have investigated the impact of listening training on elements of the singer's skill set, including but not limited to measures of vocal quality such as intonation, vocal control, intensity, and sonority, as well as language pronunciation and general musicianship. Anecdotal evidence, presented by performers and their observers, is also considered. The evidence generated by research studies and anecdotal reports strongly favors Tomatis-based listening training as a valid way to improve singers' performance abilities.

Description
Our research focuses on finding answers through decentralized search, for complex, imprecise queries (such as "Which is the best hair salon nearby?") in situations where there is a spatiotemporal constraint (say answer needs to be found within 15 minutes) associated with the query. In general, human networks are good in answering imprecise queries. We try to use the social network of a person to answer his query. Our research aims at designing a framework that exploits the user's social network in order to maximize the answers for a given query. Exploiting an user's social network has several challenges. The major challenge is that the user's immediate social circle may not possess the answer for the given query, and hence the framework designed needs to carry out the query diffusion process across the network. The next challenge involves in finding the right set of seeds to pass the query to in the user's social circle. One other challenge is to incentivize people in the social network to respond to the query and thereby maximize the quality and quantity of replies. Our proposed framework is a mobile application where an individual can either respond to the query or forward it to his friends. We simulated the query diffusion process in three types of graphs: Small World, Random and Preferential Attachment. Given a type of network and a particular query, we carried out the query diffusion by selecting seeds based on attributes of the seed. The main attributes are Topic relevance, Replying or Forwarding probability and Time to Respond. We found that there is a considerable increase in the number of replies attained, even without saturating the user's network, if we adopt an optimal seed selection process. We found the output of the optimal algorithm to be satisfactory as the number of replies received at the interrogator's end was close to three times the number of neighbors an interrogator has. We addressed the challenge of incentivizing people to respond by associating a particular amount of points for each query asked, and awarding the same to people involved in answering the query. Thus, we aim to design a mobile application based on our proposed framework so that it helps in maximizing the replies for the interrogator's query by diffusing the query across his/her social network.

Description
Video denoising has been an important task in many multimedia and computer vision applications. Recent developments in the matrix completion theory and emergence of new numerical methods which can efficiently solve the matrix completion problem have paved the way for exploration of new techniques for some classical image processing tasks. Recent literature shows that many computer vision and image processing problems can be solved by using the matrix completion theory. This thesis explores the application of matrix completion in video denoising. A state-of-the-art video denoising algorithm in which the denoising task is modeled as a matrix completion problem is chosen for detailed study. The contribution of this thesis lies in both providing extensive analysis to bridge the gap in existing literature on matrix completion frame work for video denoising and also in proposing some novel techniques to improve the performance of the chosen denoising algorithm. The chosen algorithm is implemented for thorough analysis. Experiments and discussions are presented to enable better understanding of the problem. Instability shown by the algorithm at some parameter values in a particular case of low levels of pure Gaussian noise is identified. Artifacts introduced in such cases are analyzed. A novel way of grouping structurally-relevant patches is proposed to improve the algorithm. Experiments show that this technique is useful, especially in videos containing high amounts of motion. Based on the observation that matrix completion is not suitable for denoising patches containing relatively low amount of image details, a framework is designed to separate patches corresponding to low structured regions from a noisy image. Experiments are conducted by not subjecting such patches to matrix completion, instead denoising such patches in a different way. The resulting improvement in performance suggests that denoising low structured patches does not require a complex method like matrix completion and in fact it is counter-productive to subject such patches to matrix completion. These results also indicate the inherent limitation of matrix completion to deal with cases in which noise dominates the structural properties of an image. A novel method for introducing priorities to the ranked patches in matrix completion is also presented. Results showed that this method yields improved performance in general. It is observed that the artifacts in presence of low levels of pure Gaussian noise appear differently after introducing priorities to the patches and the artifacts occur at a wider range of parameter values. Results and discussion suggesting future ways to explore this problem are also presented.

Description
Illuminating Silent Voices: An African-American Contribution to the Percussion Literature in the Western Art Music Tradition will discuss how Raymond Ridley's original composition, FyrStar (2009), is comparable to other pre-existing percussion works in the literature. Selected compositions for comparison included Darius Milhaud's Concerto for Marimba, Vibraphone and Orchestra, Op. 278 (1949); David Friedman's and Dave Samuels's Carousel (1985); Raymond Helble's Duo Concertante for Vibraphone and Marimba, Op. 54 (2009); Tera de Marez Oyens's Octopus: for Bass Clarinet and one Percussionist (marimba/vibraphone) (1982). In the course of this document, the author will discuss the uniqueness of FyrStar's instrumentation of nine single reed instruments--E-flat clarinet, B-flat clarinet, alto clarinet, bass clarinet, B-flat contrabass clarinet, B-flat soprano saxophone, alto saxophone, tenor saxophone, and B-flat baritone saxophone, juxtaposing this unique instrumentation to the symbolic relationship between the ensemble, marimba, and vibraphone.

Description
New music is often created as a product of commissions resulting in a collaborative effort between the performer and the composer. This performer-composer relationship represents an important component of the role of the artist in expanding the repertoire of the instrument. Belgian composer, Norbert Goddaer (b. 1933), has written numerous works for clarinet that are the result of such collaborations. Mr. Goddaer's works for clarinet are well-crafted and audience-friendly, and are thus good programming choices for students and professionals alike. His clarinet works have been performed worldwide in artist recitals, conferences for organizations such as the International Clarinet Association, The Midwest Clinic, and the Texas Music Educators Association, and have been commercially recorded and released by some of the foremost contemporary clarinet artists. These works have a great education value given the fact that they are appropriate choices for such a wide range of clarinetists. In an effort to contribute to this body of performance history, the author has produced a recording of five of Goddaer's previously unrecorded works, accompanied by a performance guide to each work. This document provides detailed performance notes with corresponding musical examples, basic formal analyses, and musical suggestions for Las Mañas, Conversations, Ballad, Duets, and Restless by Norbert Goddaer. The author has included a full transcript of an interview with Norbert Goddaer, which includes a first-person discussion of each work, and additionally includes biographical information supported by concert programs and an annotated list of all of Goddaer's works for clarinet, and a discography of his works for clarinet.

Description
The number of Brazilian immigrants in the United States has greatly increased over the past three decades. In Phoenix, Arizona, this population increase reveals itself through a greater number of large Brazilian cultural events and higher demand for live Brazilian music. Music is so embedded in Brazilian culture that it serves as the ideal medium through which immigrants can reconnect to their Brazilian heritage. In this thesis, I contend that Brazilian immigrants in Phoenix, Arizona maintain their identity as Brazilians through various activities extracted from their home culture, the most prominent being musical interaction and participation. My research reveals three primary factors which form a foundation for maintaining cultural identity through music within the Brazilian immigrant community in Phoenix. These include the common experiences of immigration, diasporic identity, and the role of music within this diaspora. Music is one of the stronger art forms for representing emotions and creating an experience of relationship and connections. Music creates a medium with which to confirm identity, and makes the Brazilian immigrant population visible to other Americans and outsiders. While other Brazilian activities can also serve to maintain immigrants' identity, it is clear to me from five years of participant-observation that musical interaction and participation is the most prominent and effective means for Brazilians in Phoenix to maintain their cultural identity while living in the U.S. As a community, music unites the experiences of the Brazilian immigrants and removes them from the periphery of life in a new society.

Description
Emily Dickinson is a well-known American poet of the nineteenth century, and her oeuvre consists of nearly 2,000 posthumously published poems. Written largely in hymn form with unique ideas of punctuation and grammar, her poetry attracts composers with its inherent musicality. The twentieth-century American composers Aaron Copland, Ernst Bacon, Lee Hoiby, and Gordon Getty have created song settings of Dickinson's poetry. Copland's song cycle Twelve Poems of Emily Dickinson (1949-50) is admired by many as an illustration of poetry; however, the Dickinson cycles by Bacon, Hoiby, and Getty are also valuable, lesser-known representations of her writing. Settings of one poem, "There came a Wind like a Bugle--", are common among Copland's Twelve Poems, Bacon's cycle Songs from Emily Dickinson: Nature, Time, and Space (1930), Hoiby's Four Dickinson Songs (1988), and Getty's The White Election (1982). These latter three settings have previously undergone some theoretical analysis; however, this paper considers a performance analysis of these songs from a singer's point of view. Chapter 1 provides background for this study. Chapter 2 consists of a biographical overview of Dickinson's life and writing style, as well as a brief literary analysis of "There came a Wind like a Bugle--". Chapters 3, 4, and 5 discuss Ernst Bacon, Lee Hoiby, and Gordon Getty, respectively; each chapter consists of a short biography of the composer and a discussion of his writing style, a brief theoretical analysis of his song setting, and commentary on the merits of his setting from the point of view of a singer. Observations of the depiction of mood in the song and challenges for the singer are also noted. This paper provides a comparative analysis of three solo vocal settings of one Emily Dickinson poem as a guide for singers who wish to begin studying song settings of this poem. The Bacon and Hoiby settings were found to be lyrical, tonal representations of the imagery presented in "There came a Wind like a Bugle--". The Getty setting was found to be a musically starker representation of the poem's atmosphere. These settings are distinctive and worthy of study and performance.

Description
Zwischen in the German language means `between,' and over the past century, as operatic voices have evolved in both range and size, the voice classification of Zwischenfach has become much more relevant - particularly to the female voice. Identifying whether nineteenth century composers recognized the growing opportunities for vocal drama, size, and range in singers and therefore wrote roles for `between' singers; or conversely whether, singers began to challenge and develop their voices to sing the new influx of romantic, verismo and grand repertoire is difficult to determine. Whichever the case, teachers and students should not be surprised about the existence of this nebulous Fach. A clear and concise definition of the word Fach for the purpose of this paper is as follows: a specific voice classification. Zwischenfach is an important topic because young singers are often confused and over-eager to self-label due to the discipline's excessive labeling of Fachs. Rushing to categorize a young voice ultimately leads to misperceptions. To address some of the confusion, this paper briefly explores surveys of the pedagogy and history of the Fach system. To gain insights into the relevance of Zwischenfach in today's marketplace, I developed with my advisors, colleagues and students a set of subjects willing to fill out questionnaires. This paper incorporates current interviews from two casting directors of national and international opera houses, an emerging American mezzo-soprano, a mid-career working European mezzo-soprano, an operatic stage director, an education director for opera houses and a composer. These interviews, along with modern examples of zwischenfach voices are analyzed and discussed.

Photovoltaics (PV) is an important and rapidly growing area of research. With the advent of power system monitoring and communication technology collectively known as the "smart grid," an opportunity exists to apply signal processing techniques to monitoring and control of PV arrays. In this paper a monitoring system which provides real-time measurements of each PV module's voltage and current is considered. A fault detection algorithm formulated as a clustering problem and addressed using the robust minimum covariance determinant (MCD) estimator is described; its performance on simulated instances of arc and ground faults is evaluated. The algorithm is found to perform well on many types of faults commonly occurring in PV arrays. Among several types of detection algorithms considered, only the MCD shows high performance on both types of faults.

Description
Musical Impressionism has been most significantly reflected through the works of Claude Debussy (1862-1918) and Maurice Ravel (1875-1937). These two key figures exhibit the essence of this art and their piano music remains substantial, influential, and frequently assigned and played today. Nevertheless, from a pedagogical perspective, important factors required in achieving a successful performance of Debussy and Ravel's piano music--delicate tone production, independent voicing, complicated rhythm, sensitive pedaling, and a knowledgeable view of Impressionism--are musically and technically beyond the limit of early advanced students. This study provides a collection of short piano pieces by nine lesser-known European and American composers--Edward MacDowell (1861-1908), Charles Griffes (1884-1920), Marion Bauer (1887-1955), Cyril Scott (1879-1970), Arnold Bax (1883-1953), Selim Palmgren (1878-1951), Ottorino Respighi (1879-1936), Jacques Ibert (1890-1962) and Federico Mompou (1893-1987). They were influenced by impressionistic aesthetics or composed at one time in an impressionistic manner over a span of their lifetimes and their music provides a bridge to the more advanced impressionistic pieces of Debussy and Ravel for early advanced students. These composers' selected short piano pieces display richly colored sonority through the use of impressionistic techniques such as non-functional harmony (parallel chords and free modulation), exotic setting (e.g. modality, pentatonic and whole-tone scales), ostinato figures, bell-sound imitation, and extended texture. Moreover, personal interpretive elements, such as poetic and folklore references, were incorporated in some piano works of MacDowell, Griffes, Bauer, Scott, and Bax; among them MacDowell and Bax were particularly inspired by Celtic and Nordic materials. Mompou infused Spanish folklores in his individual naïve style. Most importantly, these selected short piano pieces are approachable and attractive to early advanced pianists. These works, as well as other largely undiscovered impressionistic piano character pieces, ought to be a great source of preliminary repertoire as preparation for the music of Debussy and Ravel.
