Due to the accelerated growth in digital music distribution, it becomes easy to modify, intercept, and distribute material illegally. To overcome the urgent need for copyright protection against piracy, several audio watermarking schemes have been proposed and implemented. These digital audio watermarking schemes have the purpose of embedding inaudible information within the host file to cover copyright and authentication issues. This thesis proposes an audio watermarking model using MATLAB® and Simulink® software for 1K and 2K fast Fourier transform (FFT) lengths. The watermark insertion process is performed in the frequency domain to guarantee the imperceptibility of the watermark to the human auditory system. Additionally, the proposed audio watermarking model was implemented in a Cyclone® II FPGA device from Altera® using the Altera® DSP Builder tool and MATLAB/Simulink® software. To evaluate the performance of the proposed audio watermarking scheme, effectiveness and fidelity performance tests were conducted for the proposed software and hardware-in-the-loop based audio watermarking model.

Understatements for two-channel fixed media is a four-movement study of the sonic potential of acoustic instruments within the practice of electroacoustic studio composition. The musical identity of the entire composition is achieved through consistent approaches to disparate instrumental materials and a focused investigation of the relationships between the various acoustic timbres and their electroacoustic treatments. The analytical section of this paper builds on contemporary research in electroacoustic arts. The analysis of the work is preceded by a summary of theoretical and aesthetic approaches within electroacoustic composition and the introduction of primary criteria of sonic faktura (material essence) used in the compositional process. The analyses address the idiosyncratic use of the concept of faktura to contextualize and guide the unfolding of the work. The reconciliation of the illusory electronic textures and the acoustic sources that parented them may be considered the ultimate goal of Understatements.

A traditional two dimensional (planar) statistical analysis was used to identify the clustering types of North Central Texas traffic fatalities occurring in 2001-2006. Over 3,700 crash locations clustered in ways that were unlike other researched regions. A two dimensional (x and y coordinates) space was manipulated to mimic a one dimensional network to identify the tightest clustering of fatalities in the nearly 400,000 crashes reported from state agencies from 2003-2006. The roadway design was found to significantly affect crash location. A one dimensional (linear) network analysis was then used to measure the statistically significant clustering of flow variables of after dark crashes and daylight crashes. Flow variables were determined to significantly affect crash location after dark. The linear and planar results were compared and the one dimensional, linear analysis was found to be more accurate because it did not over detect the clustering of events on a network.

In a small room in Austin, Texas, a group of 15 people are single-handedly deciding what is taught to the next generation of American children. The highly politicized 15 member Texas Board of Education is currently going through the once-in-a-decade process of rewriting the teaching and textbook standards for its nearly 5 million schoolchildren. Texas is also unbelievably influential on the standards that textbook publishers use as a basis for their textbooks nationwide. Over the last 10 years, the textbooks adopted by this board found their way in upwards of 65% of American classrooms. My goal is to shed light on this important issue and the key players in this process - I explain their goals, explore the scope of their influence, and delve into the personal motivations behind their actions, which will affect public education throughout the country.

The reaction between the formamidine ligand PriN=CHNHPri and the activated cluster Os3(CO)10(MeCN)2 has been studied. A rapid reaction is observed at room temperature, yielding the hydride clusters HOs3(CO)9[μ-OCNPriC(H)NPri] and HOs3(CO)10[μ-NPriC(H)NPri] as the principal products. The spectroscopic data and X-ray diffraction structures of those formamidinate-substituted clusters will be present. The thermal reactivity of the clusters has been investigated, with the face-capped cluster HOs3(CO)9[μ-NPriC(H)NPri] found as the sole observable product. The relationship between these three clusters has been established by kinetic studies, the results of which will be discussed.

Clandestine burials, the interred human remains of forensic interest, are generally small features located in isolated environments. Typical ground searches can be both time-consuming and dangerous. Thermal remote sensing has been recognized for some time as a possible search strategy for such burials that are in relatively open areas; however, there is a paucity of published research with respect to this application. This project involved image manipulation, the analyses of signatures for "graves" of various depths when compared to an undisturbed background, and the use of image classification techniques to tease out these features. This research demonstrates a relationship between the depth of burial disturbance and the resultant signature. Further, image classification techniques, especially object-oriented algorithms, can be successfully applied to single band thermal imagery. These findings may ultimately decrease burial search times for law enforcement and increase the likelihood of locating clandestine graves.

This study of the variable use of ne in synchronous electronic French discourse follows the methodological guidelines and the theoretical framework proposed and subsequently elaborated by Labov for analyzing variable features of language. This thesis provides a quantitative variable rule (i.e., VARBRUL) analysis including age as a factor group (i.e., independent variable), thereby making a new contribution to this area of inquiry. The data (50,000 words from the vingtaine 'twentysomething' channel and 50,000 words from the cinquantaine 'fiftysomething' channel) are a subset of 100,000 words from a corpus of one million words collected in 2008 by the thesis director from the public chat server EuropNet. This study aims to answer the following overarching question: To what extent does age-compared to other factors-influence the variable use of ne in verbal negation in synchronous electronic French discourse? In order to answer this question, and possibly others, the VARBRUL analysis will include age, subject (e.g., noun vs. pronoun), type of second negative particle (e.g., pas 'not', jamais 'never', personne 'no one'/'nobody', and so forth), as well as verbal mood/tense.

Many researchers of gender studies and colonial history ignore the lives of European women in the British West Indies. The scarcity of written information combined with preconceived notions about the character of the women inhabiting the islands make this the "final frontier" in colonial studies on women. Over the long eighteenth century, travel literature by men reduced creole white women to a stereotype that endured in literature and visual representations. The writings of female authors, who also visited the plantation islands, display their opinions on the creole white women through their letters, diaries and journals. Male authors were preoccupied with the sexual morality of the women, whereas the female authors focus on the temperate lifestyles of the local females. The popular perceptions of the creole white women seen in periodicals, literature, and caricatures in Britain seem to follow this trend, taking for their sources the travel histories.
