Deconvolution of noisy data is an ill-posed problem, and requires some form of regularization to stabilize its solution. Tikhonov regularization is the most common method used, but it depends on the choice of a regularization parameter λ which must generally be estimated using one of several common methods. These methods can be computationally intensive, so I consider their behavior when only a portion of the sampled data is used. I show that the results of these methods converge as the sampling resolution increases, and use this to suggest a method of downsampling to estimate λ. I then present numerical results showing that this method can be feasible, and propose future avenues of inquiry.

The purpose of this thesis is to examine the events surrounding the creation of the oboe and its rapid spread throughout Europe during the mid to late seventeenth century. The first section describes similar instruments that existed for thousands of years before the invention of the oboe. The following sections examine reasons and methods for the oboe's invention, as well as possible causes of its migration from its starting place in France to other European countries, as well as many other places around the world. I conclude that the oboe was invented to suit the needs of composers in the court of Louis XIV, and that it was brought to other countries by French performers who left France for many reasons, including to escape from the authority of composer Jean-Baptiste Lully and in some cases to promote French culture in other countries.

This thesis explores my experience in teaching a high school music class through composition. I detail pedagogical approaches that helped to shape my lesson planning including constructivism, informal learning, and project based learning. The music education theory is put into action in a real high school setting and I explain what happened: what worked, what didn't, and what can we learn from this?

This project is a collection of four arrangements from Gustav Mahler’s Des Knaben Wunderhorn for French horn and marimba, with accompanying commentary. French horn and marimba is a beautiful combination that suffers from a lack of repertoire. These arrangements, composed by Kyle Nelson, are a step toward remedying that problem, while exploring the wide range of musical styles for which this combination is suited. The four songs that have been transcribed here are Urlicht, Wo die schönen Trompeten blasen, Der Tamboursg’sell, and Des Antonius von Padua Fischpredigt. Together, they provide a sampling of the many poems Mahler put to music in the late 1800’s for voice and piano. The sampling ranges from the very well-known (such as those featured in Mahler’s symphonies, like Urlicht) to one of the few lighthearted arrangements (Des Antonius von Padua Fischpredigt’s scherzo trio style) found in Mahler’s two original collections of lieder. The final product is performable as a duet with a talented horn and marimba duo, but in some circumstances it may be beneficial to divide the marimba part by stem direction and play as a trio on horn and two marimbas. The marimba part is best suited for four mallets on a 5-octave marimba.

Hydrogen has the potential to be a highly efficient fuel source. Its current production via steam reformation of natural gas, however, consumes a large amount of energy and gives off carbon dioxide. A newer method has since surfaced: using a microorganism's metabolism to drive hydrogen production. In this study, the conditions for maximum hydrogen production in Heliobacterium modesticaldum were identified and assessed. The cells were grown under varying conditions and their headspaces were sampled using a gas chromatogram to measure the amount of accumulated hydrogen during each condition. Two cell batches were grown under nitrogen-fixing conditions (-NH4+), while the other two cell batches were grown under non-nitrogen-fixing conditions (+NH4+). The headspaces were then exchanged with either nitrogen (N2) or argon (Ar2). It was found that the condition for which the most hydrogen was produced was when the cells were grown under nitrogen-fixing conditions and the headspace was exchanged with argon. These results suggest that most of Heliobacteria modesticaldum's hydrogen production is due to nitrogenase activity rather than hydrogenase activity. Further research is recommended to quantify the roles of nitrogenase, [NiFe] hydrogenase, and [FeFe] hydrogenase.

E-Strings Academy (www.estringsacademy.wordpress.com) is a resource website intended for the beginning violinist, violist, cellist, and bassist. The mission of the website is to extend musical learning opportunities to students outside of the physical string classroom and to engage first-year string students in musical activities at home that supplement the instruction they receive in a school setting. The current website features five different areas for students to explore: lesson videos, tunes, listening activities, games, and resources. In each area, students have the opportunity to learn and reinforce musical concepts and skill sets that they will need in order to be successful in music, both in their first year of playing and beyond. I created E-Strings Academy with the intention that I use it with my own string students in my future teaching career. It is a flexible website that I will continue to revise, adapt, and enhance to best serve the needs of my students and enrich their musical learning outside of the classroom.

Jamaican folk music is categorized into three large genres, which may be broken down into smaller more specific subgenres. Work and Social Music (which includes Work Songs, Mento Music, and Social Music), Recreational Music, and Ritual and Ceremonial Music. Rastafarianism, although it is a manifestation of ritual music, is given its own section due to the large amount of information available on the subject. Included here are historical analysis of the genres, as well as musical examples. Eight folk songs are included, and four drum patterns. This paper is intended as a resource for music educators, and therefore each song includes a Quick Reference Page, which lists solfege, rhythmic motives, genre of song, and if applicable drum rhythms which may be used to accompany the song. In addition, each song includes specific information regarding appropriate performance practice and suggestions for use in the classroom.

"Chronos" is a composition by the great jazz pianist, Aaron Parks. Originally arranged for a quartet consisting of piano, upright bass, drums and tenor saxophone, I sought to arrange the piece for a sextet consisting of trombone, alto saxophone, tenor saxophone, guitar, upright, bass, and drums. This thesis outlines my process as I transcribed "Chronos" from the original recording and then arranged it for a new ensemble. It also discusses the difficulties faced in all the phases of the project from transcribing to rehearsing and performing the work. My arrangement is included with the thesis for those who wish to analyze the music as well as a recording of a live performance of my arrangement at The Nash in downtown Phoenix on April 7th, 2015.

With the development of technology, there has been a dramatic increase in the number of machine learning programs. These complex programs make conclusions and can predict or perform actions based off of models from previous runs or input information. However, such programs require the storing of a very large amount of data. Queries allow users to extract only the information that helps for their investigation. The purpose of this thesis was to create a system with two important components, querying and visualization. Metadata was stored in Sedna as XML and time series data was stored in OpenTSDB as JSON. In order to connect the two databases, the time series ID was stored as a metric in the XML metadata. Queries should be simple, flexible, and return all data that fits the query parameters. The query language used was an extension of XQuery FLWOR that added time series parameters. Visualization should be easily understood and be organized in a way to easily find important information and details. Because of the possibility of a large amount of data being returned from a query, a multivariate heat map was used to visualize the time series results. The two programs that the system performed queries on was Energy Plus and Epidemic Simulation Data Management System. By creating such a system, it would be easier for people of the project's fields to find the relationship between metadata that leads to the desired results over time. Over the time of the thesis project, the overall software was completed, however the software must be optimized in order to take the enormous amount of data expected from the system.

This research covers the relationship between popular electronic dance music (EDM) and the seasons and climate. The precedence and relevance of the research is outlined through prior research initiatives by Karen Aplin and Paul Williams on the effect of weather on classical music. The hypothesis is that the climate will affect how music by artists residing within the climate and the seasons will affect the popularity of certain genres. Warmer climates will produce songs that are more upbeat and energetic while colder climates will result in songs that are more complex and heavy. The analysis of this hypothesis will be performed in two parts. The first will be a data driven analysis from Beatport.com's Top 100 EDM charts to observe the season's impact on genre popularity. The second will be a case study analysis of a number of artists from around the world to observe climate impact on EDM. From the analysis, we are able to draw the connection that climate does in fact have an impact on the types of music produced. Likewise, we are able to conclude that there is a distinct variation in deep house, techno/tech house, and house as a result of the seasons shifting. Techno/tech house is more popular in the warmer spring and summer months and house and deep house have a higher standing in the colder fall and winter months.
