The body of work originating from this Problem in Lieu of Thesis consists of paintings on canvas that incorporate representations of plant material. The impetus for the paintings was black and white photocopies created from mounds of plant material placed on a copy machine. The resulting copies contained forms that were organic in appearance, but unrecognizable as known objects. Parts of the most interesting and ambiguous copies were used to develop the imagery of the paintings. The new forms served the purpose of creating visual interest from unexpected images. Combined with traditional painting techniques, the selected forms produced paintings of mysterious and playful worlds similar to those parts of the environment not readily accessed, such as galactic space, microscopic organisms, and ocean depths.

Finite functions (also called maps) are used to describe a number of key computations and storage mechanisms used in software and hardware interpreters. Their presence spread over various memory and speed hierarchies in hardware and through various optimization processes (algorithmic and compilation based) in software, suggests encapsulating dynamic size changes and representation optimizations in a unique abstraction to be used across traditional computation mechanisms. We developed a memory allocator for testing the finite functions. We have implemented some dynamic finite functions and performed certain experiments to see the performance speed of these finite functions. We have developed some simple but powerful application programming interfaces (API) for these finite functions.

Recently my creative process has led to a new area of investigation and exploration. I have discovered that I enjoy the unexpected occurrences that happen while painting. I have an appreciation for the parts of my works that do not follow the preliminary sketch and are produced more subconsciously. While usually this aspect has been restricted by the adherence to a preliminary sketch and narrative, the new works explore these occurrences more fully. In the new works, I worked in a more spontaneous manner to create work that does not focus strictly on narrative but reveals itself more as a journey or exploration.

Photoresist stripping with oxygen plasma ashing destroys the functional groups in organosilicate glass films and induce moisture uptake, causing low-k dielectric degradation. In this study, hexamethyldisilazane (HMDS), triethylchlorosilane and tripropylchlorosilane are used to repair the damage to organosilicate glass by the O2 plasma ashing process. The optimization of the surface functionalization of the organosilicate glass by the silanes and the thermal stability of the functionalized surfaces are investigated. These experimental results show that HMDS is a promising technique to repair the damage to OSG during the photoresist removal processing and that the heat treatment of the functionalized surfaces causes degradation of the silanes deteriorating the hydrophobicity of the films.

Server load balancing technology has obtained much attention as much business proceeded towards e-commerce. The idea behind is to have set of clustered servers that share the load as against a single server to achieve better performance and throughput. In this problem in lieu of thesis, I propose and evaluate an implementation of a prototype scalable server. The prototype consists of a load-balanced cluster of hosts that collectively accept and service TCP connections. The host IP addresses are advertised using the Round Robin DNS technique, allowing any host to receive requests from any client. Once a client attempts to establish a TCP connection with one of the hosts, a decision is made as to whether or not the connection should be redirected to a different host namely, the host with the lowest number of established connections. This problem in lieu of thesis outlines the history of load balancing, various options available today and finally approach for implementing the prototype and the corresponding findings.

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.

"Harry Partch's Keyboard Innovation" is a computer-assisted demonstration that introduces the tuning system used primarily by the twentieth-century American composer, Harry Partch. The multimedia product was developed in Director 6.0, and it includes sound and video clips from CDs and videocassettes of Partch's works produced by Phillip Blackburn and distributed by the American Composers Forum. The content of the demonstration involves a 43-tone microtonal tuning system and its application in the music literature. This demonstration will discuss the chronological order in which these prototypes were developed and also includes samples of the tuning of notes in Partch's scale that the novice can experiment with interactively. These tones were synthesized using the Csound scores shown in Appendix B. Materials for this demonstration are based on Harry Partch's Genesis of a Music.

It has been noticed in the past five years that the Internet use has been troubled by the lack of sufficient security and a legal framework to enable electronic commerce to flourish. Despite these shortcomings, governments, businesses and individuals are using the Internet more often as an inexpensive and ubiquitous means to disseminate and obtain information, goods and services. The Internet is insecure -- potentially millions of people have access, and "hackers" can intercept anything traveling over the wire. There is no way to make it a secure environment; it is, after all, a public network, hence the availability and affordability. In order for it to serve our purposes as a vehicle for legally binding transactions, efforts must be directed at securing the message itself, as opposed to the transport mechanism. Digital signatures have been evolved in the recent years as the best tool for ensuring the authenticity and integrity of critical information in the so called "paperless office". A model using XML digital signatures is developed and the level of security provided by this model in the real world scenario is outlined.

M. catarrhalis is a gram-negative diplococci frequently associated with infections of the upper respiratory tract. During the past decade, some preliminary studies have attempted to elucidate mechanisms of adherence and haemagglutination of M. catarrhalis. These studies have reported, in many cases, inconsistent results. There are two purposes of this research. First, identify mechanisms that may potentially be associated with the adherence and haemagglutination of M. catarrhalis. Second, suggest research directions that may be fruitful in clarifying these mechanisms.

Assisted living, the fastest growing segment of the senior housing industry, allows individuals to remain as independent as they prefer and still receive necessary services. However, assisted living residences exist primarily to serve those seniors who can pay for the services from their own savings/income. We are facing a critical need for housing options for both the current senior generation and the soon-to-be-retired baby boomers. How will access to assisted living be opened to all types of payors? How will states fund the growth of assisted living? The purpose of this paper is to discuss opportunities for expansion that will make assisted living an affordable option for the low- and moderate-income elderly.

The use of animal models in research has led to a fierce debate between animal rights activists and scientists. The former claim that little useful information is gained from animal studies and the suffering of animals does not preclude any treatments which may be used to treat human illnesses. Yet, research scientists claim that in vivo animal models are of absolute necessity to developing treatments and cures to disease. To determine the necessity of animal use, one must examine the models currently in research. Have the animal models for disorders such as cystic fibrosis and muscular dystrophy given scientists enough information to develop effective treatments? This paper will examine the role of animal subjects in several disease research protocols, as well as the applicability of the research.

Chapter I describes the purpose of the project, which was to develop a body of work that exhibits all that I am at this point in time. The questions I presented to myself were the following: 1. A successful piece is defined by what parameters? 2. What visual qualities indicate my passion for clay and my enthusiasm for life? Chapter II lists and explains the five parameters of a successful piece, which are composition, firing, mark making, color contrast, and movement. Furthermore there is an explanation on how these parameters visually display my passion for clay and my enthusiasm for life. Chapter III is a summary concluding that by discovering my five parameters of a successful piece I now understand the elements that I am searching for in my work. My work will grow from this understanding as long as I have the same passion for clay and enthusiasm for life.

Organic forms representing nature, but not particular species, are combined with elements signifying attitudes toward the natural world with an emphasis on North American culture. The viewer is encouraged to consider human effects on the environment. Aquarium Night Light and Trophy both refer to the human tendency for commercial exploitation coupled with the creation of nature images we sometimes seem to prefer over the reality of the natural world. Reliquary metaphorically connects traditional religious connotations associated with saints' relics to both a biblical injunction to use anything we needed from the natural world and our contemporary belief that exposure to nature can have beneficial effects on human mental, spiritual, and physical health.

Library information systems use different software applications and automated systems to gain access to distributed information. Rapid application development, changes made to existing software applications and development of new software on different platforms can make it difficult for library information systems to interoperate. Web services are used to offer better information access and retrieval solutions and hence make it more cost effective for libraries. This research focuses on how web services are implemented with the standard protocols like SOAP, WSDL and UDDI using different programming languages and platforms to achieve interoperability for libraries. It also shows how libraries can make use of this new technology. Since web services built on different platforms can interact with each other, libraries can access information with more efficiency and flexibility.

One of the final steps in fabricating microelectromechanical devices often involves a liquid etch release process. Capillary forces during the liquid evaporation stage after the wet etch process can pull two surfaces together resulting in adhesion of suspended microstructures to the supporting substrate. This release related adhesion can greatly reduce yields. In this report, a wet etch release method that uses polystyrene microspheres in the final rinse liquid is investigated. The polystyrene microspheres act as physical barriers between the substrate and suspended microstructures during the final liquid evaporation phase. A plasma ashing process is utilized to completely remove the polystyrene microspheres from the microstructure surfaces. Using this process, release yields > 90% were achieved. It is found that the surface roughness of gold surfaces increases while that of the silicon is reduced due to a thin oxide that grows on the silicon surface during the plasma process.

The first section explores how far I could stretch dichotomy in formal terms, while maintaining a visually resonant image. I wanted to manipulate a superficial surface filtered through "natural forms" as seen in scientific imagery. By this I wanted to create access to a place where forms could play and imagination could wander. I was seeking to find a confluence in seemingly opposing forces that would coexist in the same work. The second section answers questions I had established for myself. The most important discovery I made was about the true nature of what I called a dichotomy in my work. The last section discusses the conclusions drawn from mounting the Master of Fine Arts Exhibition. I found that my interests resided more in investigating an already confluent dualism, as opposed to reconciling a conflicting dichotomy.

As Virtual Environments (VE) become a more commonly used method of interaction and presentation, supporting users as they navigate and interact with scenarios presented in VE will be a significant issue. A key step in understanding the needs of users in these situations will be observing them perform representative tasks in a fully developed environment. In this paper, we describe the development of a test bed for interactive narrative in a virtual environment. The test bed was specifically developed to present multiple, simultaneous sequences of events (scenarios or narratives) and to support user navigation through these scenarios. These capabilities will support the development of multiple users testing scenarios, allowing us to study and better understand the needs of users of narrative VEs.

In this work, sections of bodies are joined with sections of other people's bodies in order to form a new whole. Adding or subtracting relationships can many times be uncomfortable and strange, which I depict in my invented individuals based on the phases of family, such as birth, death, marriage, divorce, and the acquisition of new forms of family. This work questions issues of the family in terms of its definition, whether biologically or culturally constructed. I am creating hybrids by separating body parts from the whole and then recombining them to form a new individual. These images are a result of thinking about the possibilities and changes that people go through as a result of the new growth or loss of relationships. This work is intended to bring awareness to the way in which people relate and families become more blended.

Tuberculosis in the nursing home is an ever-growing problem for the health care community. The incidence of tuberculosis in the United States has risen alarmingly since 1982, and high-population environments such as nursing homes are among the places where it is most prevalent. The first part of this document is an introduction to the current concerns faced by nursing home infection control personnel. It includes information about the history, symptoms, and epidemiology of the disease, as well as other topics. The second part is a policy and procedure manual that contains a basic guide to methodical testing for tuberculosis, steps for dealing with active cases of the disease, and suggestions for education of nursing home health care workers.

In software testing, it is often desirable to find test inputs that exercise specific program features. Finding these inputs manually, is extremely time consuming, especially, when the software being tested is complex. Therefore, there have been numerous attempts automate this process. Random test data generation consists of generating test inputs at random, in the hope that they will exercise the desired software features. Often the desired inputs must satisfy complex constraints, and this makes a random approach seem unlikely to succeed. In contrast, combinatorial optimization techniques, such as those using genetic algorithms, are meant to solve difficult problems involving simultaneous satisfaction of many constraints.

The nature of clay's physical attributes and the application of these characteristics to an expression of gestural movement in utilitarian ceramics.

In this project a bacteria's ability to bind to human lung tissue was investigated. To carry out this study Pseudomonas aeruginosa, Eschericia coli and Burkholderia cepacia were used. B. cepacia served as the bacterium of interest. Isolating the gene which confers upon this bacterium the ability to bind to lung tissue was the main objective of this study. P. aeruginosa has been identified as being the bacteria most responsible for causing serious lung infections that can result in cystic fibrosis. This bacterium therefore served as the positive control in this study. On the contrary, E. coli does not possess this binding ability and served as the negative control. This paper gives a detailed outline of the different procedures necessary for the successful completion of this project. Firstly, a broad guideline of the important steps involved are explored. This is followed by a discussion on potential problems and possible solutions. Throughout the document, illustrations of expected results are indicated so as to further guide the researcher.

Hispanics are the fastest growing minority group in the U.S. and signs indicate a similar trend in their college enrollment. Leisure activities are known to have a moderating effect on individuals experiencing stress in their lives. Hispanic organizations registered with a major 4-year metropolitan university were targeted. The hypothesis for this study was there is no relationship between acculturation stress and leisure satisfaction. Results indicate no relationship between acculturation stress and leisure satisfaction. One explanation for this lack of a significant relationship between these two measures might be that these college students had obtained a high level of acculturation, which would explain the relatively low level of acculturation stress reported.

The body of work created during this exploration indicates that painting approach can actively integrate with the clay element. The main point is the surface manipulation during this process. There are four factors relate to this manipulation: timing, action, style, and size. Overall, the painting approach can be modified to create a truly active relationship with clay element. The final touch by the fire and glazing techniques reflect paintings approach may be used in a variety way to decorate the clay element without any limits. Moreover, the painting approach need not be subordinate to the clay element. It can be used not only to complement the clay, but also to enhance any given clay pieces no matter what the shape is.
