The focus of my work is the incorporation of three-dimensional sculptural forms into the design of my garments while still maintaining the functional purpose of the garment. Origami paper folding is the inspiration for the sculptural forms. The major endeavor was to explore and solve the relationship between the organic human forms and the geometric forms created by the origami paper folds. This presented a challenge of exact precision. During this process, I experimented with different fabrics, which can accommodate the sharp creases and retain the shape. A variety of folding patterns were also explored. Although the design should be innovative and creative, the final garment must be wearable and comfortable.

Secure communication is the primary challenge in today's information network. In this project an efficient secret key agreement protocol is described and analyzed along with the other existing protocols. We focus primarily on Leighton and Micali's secret-key agreement without the use of public-key encryption techniques. The Leighton-Micali protocol is extremely efficient when implemented in software and has significant advantages over existing systems like Kerberos. In this method the secret keys are agreed upon using a trusted third party known as the trusted agent. The trusted agent generates the keys and writes them to a public directory before it goes offline. The communicating entities can retrieve the keys either from the online trusted agent or from the public directory service and agree upon a symmetric-key without any public-key procedures. The principal advantage of this method is that the user verifies the authenticity of the trusted agent before using the keys generated by it. The Leighton-Micali scheme is not vulnerable to the present day attacks like fabrication, modification or denial of service etc. The Leighton-Micali protocol can be employed in real-time systems like smart cards. In addition to the security properties and the simplicity of the protocol, our experiments show that in …

This project in lieu of thesis identifies successful methods of fundraising utilized by a sampling of three secondary theater arts programs from North Texas. Programs were evaluated on their ability to fund their programs and provide a quality arts education for their students. Guidelines for fundraising were developed that allow secondary theater programs to flourish without placing an additional burden on already overextended tax system. Findings were framed in a Marxist socio-economic context, seeking to find some relation between supply-side economics and the failure of certain communities to offer quality arts programs. Marxist philosophy, emphasizing the values of community and shared wealth, served to frame findings in the context of arts programs serving and enhancing their own communities.

In 1993, 38.9 million people were covered by a 401(k) plan, up from 7.1 million in 1983. The rapid growth of 401(k) and other defined contribution pension plans may alter retirement patterns of older workers. Previous research showed that the spread of defined benefit plans, with sharp age-related incentives first discouraging and later encouraging retirement, contributed to the early retirement trend of past decades. Defined contribution plans differ along several dimensions, especially in their smooth rate of pension wealth accrual. Data from the Health and Retirement Study show that retirement patterns have begun to change as defined contribution plans have spread. Estimates indicate that the financial incentives in defined benefit pensions lead people to retire almost two years earlier, compared to people with defined contribution plans.

A genomic clone containing a 16.9-kb segment of cotton DNA was found to encompass a D-12 fatty acid desaturases (FAD2-4) gene. The FAD2-4 gene has a single, large intron of 2,780 bp in its 5'-untranslated region, just 12 bp upstream from the ATG initiation codon of the FAD2-4 opening reading frame. A number of prospective promoter elements, including several light-responsive sequences, occur in the 5'-flanking region. The coding region of the gene is 1155 bp with no introns, and would encode a FAD2-4 polypeptide of 384 amino acids. The putative protein had four membrane-spanning helices, hallmarks of an integral membrane protein, and would probably be located in the endoplasmic reticulum. The FAD2-4 gene is indeed a functional gene, since yeast cells transformed with a plasmid containing the coding region of the gene synthesize an appreciable amount of linoleic acid (18:2), not normally made in wild-type yeast cells. The FAD2-4 gene has many structural similarities to the cotton FAD2-3 gene that was also analyzed in this laboratory.

Chapter 1 discusses how the concept of the stitch as art object evolved. The question in the statement of problems concerned the use of design principles on the stitch and the perception of the stitch by the viewer. Chapter 2 discusses the various processes involved in creating the works to answer the proposed questions, and discusses the use of literalism in the concept of the works. Chapter 3 discusses what was learned from the experience.

I want to find a balance within the juxtaposition of representational imagery, patterned fabric, stain and found objects, which effectively communicates the ideas of my work, yet still provides a visually interesting object/painting. How do my materials relate to the content and/or meaning of the work? How will focusing on a single subject affect the development and visual content of my painting? How will I choose representational images to use in relation to the aims of my subject? I was struck by the connections between the baby doll and the real baby. The baby doll became a representation of an idealized body. My interest in baby doll source materials evolved through several different stages, beginning with drawings of baby dolls, then actual doll parts, and finally to imagery of babies with genetic defects. Formally, the work was able to progress as the idea or content progressed.

Through my work, I explored the application of texture and materials as a means to identify specific functions. I show how texture and material selections that specifically engage the sense of touch can aid in effective environments for the elderly. By means of this study, I demonstrated how the sensory perception of the elderly is utilized in designing productive environments for the senior population in regards to the sense of touch. The interior design of senior living environments can greatly enhance the retirement experience for the elderly population. With the information I have gained through my research and work will reflect in my future design projects. I also wish to share this enlightenment with others in my field of study.

California legislated the restructuring of its electric power industry in 1996. Deregulation was successful until 2000 when crisis, caused by a number of outside forces and flawed legislation, sent wholesale electric prices skyrocketing. Restructuring of the electricity sector in Texas occurred in two phases. The first phase began in 1995, when wholesale markets were opened to competition; the second phase began June 18, 1997, when the 1999 Texas Electric Choice Act, was signed into law. Deregulation has largely been successful in Texas. This analysis examines the legislation of these states and how they differed, setting the stage for one unsuccessful and one successful move to retail competition in the electricity industry.

This problem in lieu of thesis report presents a study on gate electrode materials on high K dielectrics, including poly-SiGe and Ru. The stability of poly-SiGe in direct contact with Hf silicon-oxynitride (HfSiON) is studied by rapid thermal annealing (RTA), Rutherford backscattering spectrometry (RBS), X-ray photoelectron spectroscopy (XPS) and high resolution transmission electron microscopy (HRTEM). By performing a series of RTA treatments we found that as RTA thermal budgets reach 1050 C for 30s, the poly-SiGe layer begins to intermix with the HfSiON film, as observed by TEM. The maximum annealing condition for the Hf0.14Si0.23O0.46N0.17 film to remain stable in contact with poly-SiGe is 1050 C for 20s in high purity N2(99.9%) ambient. We also found that after 1000 C annealing for 60s in a nitrogen ambient, the poly-SiGe crystal phase structure was changed from a columnar structure to a large grain structure. For a metal gate, Ru was studied to determine N2annealing effects on sheet resistance of Ru sample electrodes and electrical characterization of Ru/HfSiOx/Si stack. Results show that a pure Ru metal gate is not a good choice for high k materials since it is hard to etch off, and different annealing conditions can cause large changes in …
