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

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

Date: December 2013
Creator: Harris, Joshua Kimball
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. “Sunken Monadnock: Composing with Visual Metaphors” is a companion critical essay that takes the surface/subject metaphor as a starting point for analyzing Sunken Monadnock.Other visual metaphors that inspired Sunken Monadnock, and are discussed in the essay, include Shakir Hassan Al Said’s mystical semiotics, Jasper Johns’s crosshatch prints, and Wassily Kandinsky’s theory of abstraction. The circle and spiral, especially, play influential roles in Sunken Monadnock as reflected by musical applications of repetition, rotation, compression/rarefaction, and endlessness. The void in the circle’s center also comes into play. The nature of the work’s formal counterpoint requires an innovative approach to the score, which consists of five sections, each of which reflects a different approach to the aural surface (i.e., to the traversal of time). The two outer sections are traditionally scored, but the three ...

Sunlight readability and luminance characteristics of light-emitting diode push button switches.

Sunlight readability and luminance characteristics of light-emitting diode push button switches.

Date: May 2004
Creator: Fitch, Robert J.
Description: Lighted push button switches and indicators serve many purposes in cockpits, shipboard applications and military ground vehicles. The quality of lighting produced by switches is vital to operators' understanding of the information displayed. Utilizing LED technology in lighted switches has challenges that can adversely affect lighting quality. Incomplete data exists to educate consumers about potential differences in LED switch performance between different manufacturers. LED switches from four different manufacturers were tested for six attributes of lighting quality: average luminance and power consumption at full voltage, sunlight readable contrast, luminance contrast under ambient sunlight, legend uniformity, and dual-color uniformity. Three of the four manufacturers have not developed LED push button switches that meet lighting quality standards established with incandescent technology.

Supercritical CO2 foamed biodegradable polymer blends of polycaprolactone and Mater-Bi.

Supercritical CO2 foamed biodegradable polymer blends of polycaprolactone and Mater-Bi.

Date: December 2007
Creator: Ogunsona, Emmanuel Olusegun
Description: Supercritical CO2 foam processing of biopolymers represents a green processing route to environmentally friendly media and packaging foams. Mater-Bi, a multiconstituent biopolymer of polyester, starch and vegetable oils has shown much promise for biodegradation. The polymer, however, is not foamable with CO2 so blended with another polymer which is. Polycaprolactone is a biopolymer with potential of 4000% change in volume with CO2. Thus we investigate blends of Mater-Bi (MB) and polycaprolactone (PCL) foamed in supercritical CO2 using the batch process. Characterization of the foamed and unfoamed samples were done using X-ray diffraction (XRD), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). Micrographs of the samples from the SEM revealed that the cell size of the foams reduced and increased with increase in MB concentration and increase in the foaming temperature respectively. Mechanical tests; tensile, compression, shear and impact were performed on the foamed samples. It was noted that between the 20-25% wt. MB, there was an improvement in the mechanical properties. This suggests that at these compositions, there is a high interaction between PCL and MB at the molecular level compared to other compositions. The results indicate that green processing of polymer blends is viable.

Supercritical Silylation and Stability of Silyl Groups

Supercritical Silylation and Stability of Silyl Groups

Access: Use of this item is restricted to the UNT Community.
Date: May 2006
Creator: Nerusu, Pawan Kumar
Description: Methylsilsesquioxane (MSQ) and organosilicate glass (OSG) are the materials under this study because they exhibit the dielectric constant values necessary for future IC technology requirements. Obtaining a low-k dielectric value is critical for the IC industry in order to cope time delay and cross talking issues. These materials exhibit attractive dielectric value, but there are problems replacing conventional SiO2, because of their chemical, mechanical and electrical instability after plasma processing. Several techniques have been suggested to mitigate process damage but supercritical silylation offers a rapid single repair step solution to this problem. Different ash and etch damaged samples were employed in this study to optimize an effective method to repair the low-k dielectric material and seal the surface pores via supercritical fluid processing with various trialkylchlorosilanes. Fourier transform infrared spectroscopy (FTIR), contact angle, capacitance- voltage measurements, and x-ray photoemission spectroscopy, dynamic secondary ion mass spectroscopy (DSIMS), characterized the films. The hydrophobicity and dielectric constant after exposure to elevated temperatures and ambient conditions were monitored and shown to be stable. The samples were treated with a series of silylating agents of the form R3-Si-Cl where R is an alkyl groups (e.g. ethyl, propyl, isopropyl). Reactivity with the surface hydroxyls was inversely ...

Superintendent Preparation for the 21St Century

Superintendent Preparation for the 21St Century

Date: August 2012
Creator: Gober, Courtney Carson
Description: This study focused on the perceptions of six superintendents regarding the state of the profession as of 2012, and it reports their thoughts and suggestions as to what preparation is needed by superintendents for the 21st century. The participating superintendents, who were all members of the Western States Benchmarking Consortium, were employed in six school districts in five states. Data were collected through surveys and telephone interviews. The findings of this study clearly indicate a lack of cohesion between what superintendents learned in their university professional preparation programs and what they practice in their day to day activities. The superintendents involved in this study tended to favor a hybrid approach – rigorous theoretical insight grounded in real world practice. Since superintendents typically spend a good deal of their time solving challenging problems including funding shortfalls, competition from other educational institutions, and the constant scrutiny of the media; their preparation needs to provide opportunities to develop their leadership skills and solve real world problems in an environment where they can take risks. Mentoring and participation in professional consortiums were recommended as key elements for the preparation of the twenty-first century superintendent. This study contributes to the discussion of how to best ...

Superior Mirth: National Humor and the Victorian Ego

Superior Mirth: National Humor and the Victorian Ego

Date: May 2012
Creator: Stober, Katharyn L.
Description: This project traces the wide and varied uses of patriotic (and, at times, jingoistic and xenophobic) humor within the Victorian novel. a culture’s humor, perhaps more than any other cultural markers (food, dress, etc.), provides invaluable insight into that nation’s values and perceptions—not only how they view others, but also how they view themselves. in fact, humor provides such a unique cultural thumbprint as to make most jokes notoriously untranslatable. Victorian humor is certainly not a new topic of critical discussion; neither is English ethno-cultural identity during this era lacking scholarly attention. However, the intersection of these concerns has been seemingly ignored; thus, my research investigates the enmeshed relationship between these two areas of study. Not only do patriotic sentiment and humor frequently overlap, they often form a causational relationship wherein a writer’s rhetorical invocation of shared cultural experiences creates humorous self-awareness while “inside” jokes which reference unique Anglo-specific behaviors or collective memories promote a positive identity with the culture in question. Drawing on and extending the work of James Kincaid’s Dickens and the Rhetoric of Laughter, Harold Nicolson’s “The English Sense of Humor,” and Bergson’s and Freud’s theories of humor as a social construct, I question how this reciprocated ...
