Texas Cities and the Economic Development Sales Tax (open access)

Texas Cities and the Economic Development Sales Tax

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.

Fashion Circles (open access)

Fashion Circles

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.

Refactoring FrameNet for Efficient Relational Queries (open access)

Refactoring FrameNet for Efficient Relational Queries

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.

Self-Optimizing Dynamic Finite Functions

Access: Use of this item is restricted to the UNT Community
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.

Painting with Clay

Access: Use of this item is restricted to the UNT Community
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.

Web Services for Libraries

Access: Use of this item is restricted to the UNT Community
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.

Ballistic Deposition: Global Scaling and Local Time Series. (open access)

Ballistic Deposition: Global Scaling and Local Time Series.

Complexity can emerge from extremely simple rules. A paradigmatic example of this is the model of ballistic deposition (BD), a simple model of sedimentary rock growth. In two separate Problem-in-Lieu-of Thesis studies, BD was investigated numerically in (1+1)-D on a lattice. Both studies are combined in this document. For problem I, the global interface roughening (IR) process was studied in terms of effective scaling exponents for a generalized BD model. The model used incorporates a tunable parameter B to change the cooperation between aggregating particles. Scaling was found to depart increasingly from the predictions of Kardar-Parisi-Zhang theory both with decreasing system sizes and with increasing cooperation. For problem II, the local single column evolution during BD rock growth was studied via statistical analysis of time series. Connections were found between single column time series properties and the global IR process.

Machine Language Techniques for Conversational Agents (open access)

Machine Language Techniques for Conversational Agents

Machine Learning is the ability of a machine to perform better at a given task, using its previous experience. Various algorithms like decision trees, Bayesian learning, artificial neural networks and instance-based learning algorithms are used widely in machine learning systems. Current applications of machine learning include credit card fraud detection, customer service based on history of purchased products, games and many more. The application of machine learning techniques to natural language processing (NLP) has increased tremendously in recent years. Examples are handwriting recognition and speech recognition. The problem we tackle in this Problem in Lieu of Thesis is applying machine-learning techniques to improve the performance of a conversational agent. The OpenMind repository of common sense, in the form of question-answer pairs is treated as the training data for the machine learning system. WordNet is interfaced with to capture important semantic and syntactic information about the words in the sentences. Further, k-closest neighbors algorithm, an instance based learning algorithm is used to simulate a case based learning system. The resulting system is expected to be able to answer new queries with knowledge gained from the training data it was fed with.

Deposition and Characterization of Pentacene Film. (open access)

Deposition and Characterization of Pentacene Film.

Many organic materials have been studied to be used as semiconductors, few of them being pentacene and polythiophene. Organic semiconductors have been investigated to make organic thin film transistors. Pentacene has been used in the active region of the transistors. Transistors fabricated with pentacene do not have very high mobility. But in some applications, high mobility is not needed. In such application other properties of organic transistors are used, such as, ease of production and flexibility. Organic thin film transistors (OTFT) can find use as low density storage devices, such as smart cards or I.D. tags, and displays. OTFT are compatible with polymeric substrates and hence can find use as flexible computer screens. This project aims at making 'smart clothes', the cheap way, with pentacene based OTFT. This problem in lieu of thesis describes a way to deposit pentacene films and characterize it. Pentacene films were deposited on substrates and characterized using x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The substrate used was ~1500Å platinum on silicon wafer or bare silicon wafer. was used. A deposition system for vacuum deposition of pentacene was assembled. The XRD data for deposited pentacene films shows the presence of two phases, single …
