It has become increasingly important to remain on the cutting edge of technology for a company to remain competitive and survive in today's high-tech industries. To do this, a company needs various resources dedicated to this cause. One of these resources is the use of existing materials, as starting points, for which improved materials can be based. For this, a company must rely on the characterization of existing materials to bring that base technology into their company. Through this evaluation, the base materials properties can be obtained and a material with improved properties can be developed. There are many techniques that can be used in characterizing an existing material, but not every technique is required to obtain the desired goal. The techniques utilized depend upon the depth of identification required. This report summarizes several techniques utilized in the characterization of existing materials and provides some examples of evaluated products.

The rheology of 1-8% hydroxypropyl cellulose (HPC) solutions has been studied in the temperature range of 20-45 degrees Celsius. The results showed that the relative viscosity at each HPC concentration decreases with increasing temperature. The relative viscosity decreases drastically at about 43 degrees Celsius due to a phase transition. The influence of anionic surfactant, sodium dodecylsulfate (SDS), induced gelation of a 2% HPC solution. The HPC solutions gelled at surfactant SDS concentrations ranging from 0.4 to 1.0 critical micelle concentration (CMC). The gelation of the HPC/SDS hydrogel is explained in the surfactant SDD - bridged HPC linear polymer chains. The complex viscosity - concentration profile was determined below the CMC of the SDS - water pair. The peak itself was a function of frequency indicating the presence of two relaxation times within the gelled network.

The first chapter of this descriptive paper outlines a problem, proposes a solution and poses three questions for me to answer after completion of research. The problem was to bring an emerging ceramic style into all of my pieces rather than just the few I have mastered. The solution was to create three sets of new forms and make them repeatedly until they boasted the sought-after style. Chapter 2 chronicles the research of creating, morphing, detailing and finally mastering these new forms. Chapter 3 summarizes the experience and answers the three aforementioned questions: (1) What is my personal definition of a successful pot? (2) How does the undulating style affect the functionality of the pot? (3) How does the Campbell tartan glazing complement or detract from the pot's form?

My creative intent is to connect with viewers at an emotional level. My chosen metaphor is “Peeling the Onion.” The implication of the metaphor is that understanding is achieved after one looks below the surface and views the underlying “layers.” The challenge is to find images that are personally interesting and also connect with the viewer. At times the creative process proceeds in linear manner and at other times it seems to take on a life of its own. During my search for a balance between the literal and ambiguous, I explored the circle, the spiral and the sphere. Printmaking offers unique opportunities to produce evocative imagery. Drawing is the basic tool I employ to define form and my use of printmaking processes allows for evolving the image over time. The immediacy and spontaneity of my drawings is combined with a methodical approach to image development. Exploring the spiral, sphere, circles and the metaphor “Peeling the Onion” has provided me a means of giving a form to my concepts and hopefully a connection with the viewer.

Regional population growth and increasing trade with Mexico are creating severe traffic congestion along Interstate 35 and at the Laredo bridge crossings. The construction of a new Interstate Highway 69 has been offered as one solution to this problem. This analysis examines the economic impacts of building Interstate 69 and its potential impact on job creation in the counties along its projected path. Using the IMPLAN input-output modeling system, construction of Interstate 69 will support $4.2 billion in economic activity in the counties through which it will pass. More importantly, based on an analysis of Interstate 27 in west Texas, it can be projected that Interstate 69 will spur a 2% gain in regional employment above any usual economic growth.

Jewelry has been used as a gift exchange between lovers for many centuries. It has been conveyed in a variety of forms to symbolize the meaning of love. This body of work is associated with glory of love, of sexual experience between lovers representing the idea of unity when two parts become one unit, not only in the physical sense, but also in the psychical sense. The works were divided into three series including three pair of rings, two pair of lockets, and five pair of necklaces. The erotic expression has been addressed on every piece in an abstract way counting design motifs, material used, and interaction within the piece itself. Moreover, each piece has romantic meanings and essential aspects as a symbol of love.

I proposed in my paper to use juxtaposition of unexpected scale in my sculpture, with the expectation that it would create an unexpected tension that is visually stimulating to the viewer. I achieved this by creating disharmony in scale between an object that is perceived as miniature and an object that is perceived as gigantic within each sculpture. I then asked three questions of these sculptures: Was I able to alter the viewer's preconceived notions of the miniature and the gigantic through the manipulation of the size relationship between two objects within each sculpture? Which of these preconceived notions of the miniature or the gigantic became dominant as the main focal point in each sculpture? Did this intentional use of disharmony in scale stimulate enough of my interest to continue investigating this idea? I wrote about three sculptures that had been made for this project. The first was Manifest Destiny, a seven and a half foot tall bronze piece depicting an oil drill with a platform in the shape of the state of Texas. On the platform a gigantic bronze figure rides a miniature bronze donkey across the platform. The second bronze sculpture I wrote about was Gulliver in Suburbia; …

After generating work for many years in an intuitive, “truth to materials” mindset my intent was to explore the interior possibilities of my sculptural forms and relate these if possible, to the exterior. Alongside this exploration of the interior I introduced surface texture and color onto both interior/exterior surfaces. In some cases the work had undergone a change, which lent new meaning and provided new relationships to exist between the interior/exterior of my sculpture. Not all of the work was satisfactory to me, though I feel there were many positive results from work that may not have been successful. I found that the integration of the interior/exterior dialogue into my existing work provided new meaning allowing new relationships within the work that had not existed previously.

Through my art I seek to communicate the continuing cycle of change that unites all life forms. I had to find methods of presentation and surface that would enhance my sculptural statements that I had begun to address. Utilizing salt, wood and low temperature sagger firing, resulted in softer, more natural appearing surfaces. These surfaces complimented and completed the organic forms with which I was working. The problems encountered in presentation were rectified by alternately contrasting the surfaces of the presentation with the surfaces of the pieces, while utilizing forms that echoed the natural forms of the pieces. The opposite approach also worked well, using natural presentation materials to create a sense of unity, and geometric bases for contrast. These methods resulted in an increased sense of energy, unity and completion in the work presented.

This paper is an experiment using digital video to locate and identify the abstract in everyday life and nature. The abstract moment occurs when the image that is captured by video loses its connection with the original context, allowing the images to be viewed in an entirely new way. The abstract moment is initiated by a transformative instant, that instant in which perception is altered and the viewer sees the intended content of composition of light and sound. The project contains four digital videos that record the artist's progress and interests.

The focus of this thesis is the conveyance of moods through clothes, the communication of feelings through fashion. The thesis illustrates how clothes speak, and the tools used to communicate a visual message. Three moods are used as examples: Serenity, Valor and Love. The thesis presents the author's design ability, creative personality, cultural background and technical skills. Sources of data range from personal experience to books on Cultural Studies, armor and mask making, Indian/ Asian dance and theatre, fabric design, fabric manipulation and websites on related topics. The chapters discuss background information of the author and the topic of research, and present each ensemble created to support the thesis. Through design details and photographs of the nine ensembles, the thesis demonstrates different techniques of achieving visual communication through clothes.

Competition to lure corporations has become an enormous issue between states. Smaller communities feel unable to participate in economic development opportunities since their budgets do not provide the necessary funding. In 1979, the Texas state legislature passed the Development Corporation Act in an attempt to aid the smaller communities' quest for economic development. The Act allowed for the creation of local development corporations; however, it did not provide a sufficient funding source to assist the corporations. Therefore two local sales options were established. This paper reports the findings of an analysis of per capita income and employment changes after the adoption of an economic development sales tax. The analysis showed no statistically significant impacts on cities adopting an economic development sales tax when compared with non-adopting cities.

Through this body of work and this paper the possibilities of using Fashion Design to express the concepts of the circle has been explored. This was done with three questions in mind: How can I use the shape of the circle as inspiration for fashion design? How can I express related words and phrases in my design? and How can I use the colors black and white to emphasize the concept of my design. To answer these questions I have created two groups of garments: one was inspired by circular objects, such as cherries and drops, and the other starting from words and phrases such as "study circle" and "circle the wagons." In the first group the emphasis was on the aesthetics of the garment while the second group was more focused on meaning. All garments are black and white.

The FrameNet database is being used in a variety of NLP research and applications such as word sense disambiguation, machine translation, information extraction and question answering. The database is currently available in XML format. The XML database though a wholesome way of distributing data in its entireness, is not practical for use unless converted to a more application friendly database. In light of this we have successfully converted the XML database to a relational MySQL™ database. This conversion reduced the amount of data storage amount to less than half. Most importantly the new database enables us to perform fast complex querying and facilitates use by applications and research. We show the steps taken to ensure relational integrity of the data during the refactoring process and a simple demo application demonstrating ease of use.

When I was first introduced to photography, I was mainly drawn to landscape imagery. I enjoyed being a solitary spectator. Over time, inclusions of figurative elements became more and more apparent in my work. I purposefully began to incorporate a figure into my landscapes, ascribing to it a certain nostalgia and a sense of isolation I was experiencing on many levels at that time. Before long, I felt disconnected from these images because of their ambiguity and generalization. I found myself craving more content and personal commitment in my photography. At the end 2003, I started experimenting with a 4" x 5" format camera, which forced me, to some extent, to change my way of photographing and seeing. That is how the beginning of this new body of work was born. I was accustomed to shooting with a 35 mm camera, which allowed me to be spontaneous, quick and immediate. I permanently switched to a large format. I could see myself benefiting from this change. I lost some of the spontaneity that a 35 mm format offers but I gained the beauty of working with larger negatives and the endless possibilities of view camera movements. Thanks to this technical transformation, …

The purpose of this study is to examine housing construction trends in the Denton Independent School District area for the next 5 years estimating impacts on the resulting school district enrollments. Combining enrollment data obtained from the DISD and housing data from the Denton County Appraisal District, it is possible to calculate enrollment multipliers for elementary, middle, and high school students based on predefined categories of single family home values. The study suggests that enrollment multipliers currently used by the DISD over estimate the number of students coming from new single family residences, especially at the elementary school level. Using data from real estate agents, builders, developers, and permitting boards, a map is created showing areas of the DISD that will likely see the largest gains in school-age children during the next 2 to 5 years.

Most of my childhood was spent in either the expansive suburbs of north Texas or on a farm in southern Oklahoma. The experience of growing up in these two regions has done much to shape my sense of aesthetic. From these early experiences, I have developed two completely divergent ideas of beauty which I've tried to reconcile in my artwork. The first influence is that of sparseness, simplicity and the commonplace. This influence comes from the emptiness of the suburban landscape, the sameness of its architecture and the need to find beauty in mundane things as a simple cure for boredom. The second major idea is centered around peculiarity, chaotic complexity and irrationality. This interest originally stems from early memories of my grandfather, whose experiences in Oklahoma during the Great Depression gave him the obsessive habit of never discarding anything for fear that he might need it some day. The complexity in meaning that comes from unfamiliar combinations has allowed the ideas in my work a kind of ambiguity that frees it from any singular reading. I think the content of my work could best be described as constructions of memories, experiences and influences. I never speak about any one …

Modernist painters such as Picasso, Ernst and Matisse were among others who incorporated what was then considered "primitive" art, mostly from Africa and Oceania, into their works. Prior to this, European artists had appropriated Greco-Roman themes and characters. These appropriated elements were consequently recreated without their cultural context and content, altered to reflect more current themes. In most cases, attention was directed toward the recreator, the author of the new work of art, not the creator of the artifact. In contrast, Post-Modern artists, including myself, have reproduced appropriated elements virtually unaltered as a way of denying authorship and emphasizing a more conceptual format. Appropriated imagery has been a tool for me in my work. Additionally, both figurative and abstract elements play significant roles since I consider juxtaposition of elements to be a strength. The challenge of fitting these elements together has enabled me to develop a style of painting that seems uniquely mine. The formal issues of style and content figure heavily in my endeavor to capture a moment in time; something lost forever except for its persistence in memory. These reflections are often imbued with personal icons, arcane text and symbolic drawing that weave in and out of the …

From its inception, the direction of The Fantasticks has been a fascinating and wonderful educational experience. When I first submitted my proposal to do the show, I had not intended for it to be my problem in lieu of a thesis, but rather a beginning directing project. I had no idea that the submission would meet with such opposition. I figured this was a lesson in "real life," for it is a widely recognized fact that getting a show produced requires much salesmanship and determination. When informed that I would be able to use this production for my master's thesis project, I was both delighted and frightened. After all, I had never directed a show before; and I wasn't really sure what I was getting myself into. In addition, I would be going about this project backwards. Usually, when such a project is contemplated, the thesis research is done first; and the direction of the show done after the completion of the written work. Although I did do my homework before directing The Fantasticks; because of time constraints, I was unable to delve as deeply into the subject as I would have liked. I have often stated that this, in …

Currently, there are more than 30 million refugees and internally displaced people in the world. Since the 1970s, after the Vietnam War, international organizations and many countries have supported refugees financially, however, they all have different definitions for a refugee. Refugees who desire peace or freedom and resettle in new countries have had remarkable economic, social, and educational achievement, especially Indochinese people in the US. However, refugees who flee from conflicts have often faced new conflicts in their host society. Both refugees and the host countries experience economic and social burden, however, refugees struggle and try to escape from their economic dependency from the local government. If refugee achievements continue, they could exceed the US educational and social norm in the future.

Growth in the number of people living to very old age and progress in health care technology are creating important new challenges for our society. Among them is modern medicine's ability to extend some people's lives beyond the point where they are capable of making decisions or expressing their needs and desires, resulting in the very complex problem of knowing when to allow a person to die. In part, advance directives were created to solve this problem. Texas has been busy developing changes to existing state laws in an effort to create more "user-friendly" directives. This paper explores the history of advance directives, and discusses the details and nuances of the Texas Advance Directives Act of 1999.

In recent developments of composite materials, scientists and engineers have come up with fibers as well as matrices for composites and techniques of blending high cost components with low cost materials. Thus, one creates cost effective composite materials that are as efficient as space age components. One of the major breakthroughs in this area is the innovation of molecular composites, specifically polymeric liquid crystals (PLCs). These materials have excellent mechanical properties such as tensile impact and bending strength. They have excellent chemical resistance, low thermal expansivity, and low flammability. Their low viscosity leads to good processability One major setback in using space age composite technology in commercial applications is the price. Due to the complexity of processing, the cost of space composite materials is skyrocketing. To take the same concept of space age composite materials to create a more economical substitute has become a serious concern among scientists and engineers around the world. The two issues that will be resolved in this thesis are: (1) the potential impact of using PLCs (molecular reinforcement) can have on macro reinforced (heterogeneous composite, HC) long fiber systems; and (2) how strategic placement of the reinforcing layers can affect the macromechanical properties of the …

The purpose of this investigation is to explore the possibilities of manipulating clay in three distinct ways to effectively show that clay objects were at one time moist and pliable. The techniques used are faceting while wet, manipulating a variety of additions, applying different glazing techniques, and three separate firing methods. In addressing the problem, the following concerns were considered: (a) Which of the pieces made best expresses my aesthetic concerns? (b) Which firing method, oxidation, reduction or atmospheric, best illustrates these concerns? (c) Which glazing technique was most successful? In an attempt to explore and solve these problems, a series of twenty pieces were produced. A visual record of slides showing individual pieces were made to demonstrate the differences and similarities between firing methods.
