Redeeming the Betrayer: Elgar’s Portrayal of Judas in the Apostles

Description: Despite its generally agreed importance, very little has been written about The Apostles. Even among the extant publications that address The Apostles, scholars have focused on its history and development, its reception, or analytical descriptions of its surface themes. The aim of this study will therefore be to provide neither a biography of Elgar, nor an account of the genesis of the work, but to analyze The Apostles in a manner that will achieve a deeper understanding of the oratorio.

Statistical Strategies for Efficient Signal Detection and Parameter Estimation in Wireless Sensor Networks

Description: This dissertation investigates data reduction strategies from a signal processing perspective in centralized detection and estimation applications. First, it considers a deterministic source observed by a network of sensors and develops an analytical strategy for ranking sensor transmissions based on the magnitude of their test statistics. The benefit of the proposed strategy is that the decision to transmit or not to transmit observations to the fusion center can be made at the sensor level re… more

Phototoxic Effects of Titanium Dioxide Nanoparticles on Daphnia Magna

Description: Titanium dioxide nanoparticles (TiO2-NP) are one of the most abundantly utilized nanomaterials in the world. Studies have demonstrated the mechanism of acute toxicity in TiO2-NP to be the production of reactive oxygen species (ROS) leading to oxidative stress and mortality in exposed organisms. It has also been demonstrated that the anatase crystalline conformation is capable of catalyzing the cleavage of water molecules to further increase the concentration of ROS in the presence of ultraviole… more

Multi-year Operation Effect of Geothermal Heat Exchanger on Soil Temperature for Unt Zero Energy Lab

Description: Ground source heat pump (GSHP) uses earth’s heat to heat or cool space. Absorbing heat from earth or rejecting heat to the earth, changes soil’s constant temperature over the multiple years. In this report we have studied about Soil temperature change over multiple years due to Ground loop heat exchanger (GLHE) for Zero Energy Research Laboratory (ZØE) which is located in Discovery Park, University of North Texas, Denton, TX. We did 2D thermal analysis GLHP at particular Depth. For simulation w… more

“Sunken Monadnock”: a Composition for Flute, Clarinet, Bassoon, Violin, Violoncello, Electric Guitar, Piano, Percussion, Three Female Vocalists, and Computer

Description: Sunken Monadnock is a scripted combination of three modular musical surfaces. The word “surface” is borrowed from Morton Feldman, who compared the aural surface of music to the canvases of the action painters of the American Abstract Expressionists, and contrasted it with the work’s subject, or organizational structure. Composers’ transition toward a focus on surface through indeterminate compositional techniques, according to Feldman, parallels the development of modernist abstract art. “Sunke… more

Shakespeare and Modeling Political Subjectivity

Description: This dissertation examines the role of aesthetic activity in the pursuit of political agency in readings of several of Shakespeare’s plays, including Hamlet (1600), A Midsummer Night’s Dream (1595), The Tempest (1610), the history plays of the second tetralogy (1595-9), Julius Caesar (1599), and Coriolanus (1605). I demonstrate how Shakespeare models political subjectivity—the capacity for individuals to participate meaningfully in the political realm—as necessitating active aesthetic agency. T… more

An Examination of Innovations in Alexander Scriabin’s Late Etudes for Piano

Description: Alexander Scriabin (1872-1915) stands as one of the most unconventional twentieth-century Russian composers, particularly with respect to his piano works. The overwhelming majority of Scriabin's compositions—sixty-seven of his seventy-four published works—were written for solo piano. His etudes from 1905 forward are revolutionary, especially compared with his earlier Chopinesque style. Among Scriabin’s twenty-six etudes, his Op.49, No. 1 (1905), Op.56, No. 4 (1908) and the last three etudes of … more

Determination of Molecular Descriptors for Illegal Drugs by Gc-fid Using Abraham Solvation Model

Description: The Abraham solvation parameter model is a good approach for analyzing and predicting biological activities and partitioning coefficients. The general solvation equation has been used to predict the solute property (SP) behavior of drug compounds between biological barriers. Gas chromatography (GC) retention time can be used to predict molecular descriptors, such as E, S, A, B & L for existing and newly developed drug compounds. In this research, six columns of different stationary phases were … more

Dramatizing Lynching and Labor Protest: Case Studies Examining How Theatre Reflected Minority Unrest in the 1920S and 30S

Description: Theatre is widely unrecognized for the compelling influence it has held in society throughout history. In this thesis, I specifically examine the implications surrounding the social protest theatre of black and Jewish American minority communities in the first half of the twentieth century. I discuss how their historical circumstance, culture, and idiosyncratic natures caused them to choose agitated propaganda theatre as an avenue for protest. I delve into the similarities in circumstance, but … more

Posttraumatic Stress and Neurobehavioral Symptoms

Description: The purpose of this study is to examine the structure of neurobehavioral symptoms in service members with physical and/or psychological trauma to determine the diagnostic specificity of these symptoms. Previous literature has demonstrated that orthopedic injured, mild traumatic brain injury (MTBI), and healthy controls shared similar levels of postconcussive symptom complaints, which suggest that postconcussion-like symptoms are not unique to MTBI. To the best of my knowledge, this is the fir… more

Designing Tools to Probe the Calcium-dependent Function of Arabidopsis Tonneau2

Description: Plants possess unique features in many aspects of development. One of these features is seen in cell wall placement during cytokinesis, which is determined by the position of the preprophase band (PPB) and the subsequent expansion of the phragmoplast that deposits the new cell wall. During phragmoplast expansion, the phragmoplast tracks to the cortical division site, which was delineated by the PPB. Thus the position of the PPB determines the orientation of the division plane. In Arabidopsis … more

True Bromance: Representation of Masculinity and Heteronormative Dominance in the Bromantic Comedy

Description: This project explores the representation of white, American masculinity within the Hollywood bromantic comedy cycle. By analyzing three interrelated components (close homosociality, infantilization, and relationship to patriarchy) of the model of masculinity perpetuated by this cycle of films, this study reveals the hegemonic motives therein. Despite the representation of a masculinity nervously questioning its position within the romantic comedy narrative and the broader patriarchal structure,… more
