Efficient Techniques For Management And Delivery Of Video Data, Junghwan Oh

Retrospective Theses and Dissertations

The rapid advances in electronic imaging, storage, data compression telecommunications, and networking technology have resulted in a vast creation and use of digital videos in many important applications such as digital libraries, distance learning, public information systems, electronic commerce, movie on demand, etc. This brings about the need for management as well as delivery of video data. Organizing and managing video data, however, is much more complex than managing conventional text data due to their semantically rich and unstructured contents. Also, the enormous size of video files requires high communication bandwidth for data delivery. In this dissertation, I present the …

A Hierarchical Channel Selection Scheme For Macro/Micro Cellular Networks, Ayesha Zaheer

Retrospective Theses and Dissertations

Hierarchical channel allocation schemes for cellular networks offer a promising approach to solve the pressing problem of increasing the cellular servicing capacity in spite of the limited radio spectrum available. We propose a hierarchical channel selection scheme for handling handoffs and new calls in micro/macro cellular systems. The scheme is intended to improve the performance and quality of service of these systems by increasing the cell channel utilization, reducing the handoff blocking probability and improving the responsive to new calls.

The proposed scheme is based on several design enhancements including an overflow buffer, which is used for handoff calls that …

The Battle's Lost And Won: Ratification Of The Nineteenth Amendment In Tennessee, Judith Beale

Retrospective Theses and Dissertations

Tennessee ratified the Nineteenth amendment by a margin of one vote. This circumstance has generated myths that serve to obscure rather than enlighten the events that occurred. Historians generally attribute women winning the right to vote to the improvements in their legal status, education, and employment that encouraged women to demand the right to vote. Following suffragists' rhetoric, historians believe that national opposition to women's enfranchisement came from the liquor industry and from railroad industries because they feared that women would vote to maintain prohibition and pass regulating legislation damaging to their industries. Suffragists, therefore, mounted many campaigns that led …

View-Centric Reasoning About Parallel And Distributed Computation, Marc L. Smith

Retrospective Theses and Dissertations

The development of distributed applications has not progressed as rapidly as its enabling technologies. In part, this is due to the difficulty of reasoning about such complex systems. In contrast to sequential systems, parallel systems give rise to parallel events, and the resulting uncertainty of the observed order of these events. Loosely coupled distributed systems complicate this even further by introducing the element of multiple imperfect observers of these parallel events. The goal of this dissertation is to advance parallel and distributed systems development by producing a parameterized model that can be instantiated to reflect the computation and coordination properties …

A Multivariate Approach To The Dynamic Of Violence Within Intimate Relationships: An Application Of Theory Of Coercive Power In Exchange, Giovanna Gianesini

Retrospective Theses and Dissertations

This study, drawing from theories of structural power and exchange, verified the hypotheses that the mechanisms, dynamics, and direction of violence in intimate relationships depends on the resources of each partner, the ratio of such resources, and their summative effects. Specifically, this study developed a framework that integrates the factors found related to domestic violence and defined as resources, and took into account their reward power, with reference to the status quo of the partners, to determine each partner's power within the relationship. The resources considered have included variables from four domains, individual, relational, social structural, and sociocultural. Existing gender-based …

Crash Quality- An Approach For Evaluating Spending On Quality Improvement Initiatives, Labiche Ferreira

Retrospective Theses and Dissertations

The quality movement has become popular among corporations big and small for one reason: empirical evidence suggests that quality and productivity (and hence profitability) are linked. Unfortunately, while many firms accept that quality and productivity go together, few actually track the gains associated with their quality improvement programs. Companies also tend to spend on quality improvement with no indication or estimation of the impact of funding on the targeted process. It would be of great value to know: (1) the impact of spending to enhance the product/process quality level, and (2) the point at which expenditures for quality improvement are …

Field Evaluation Of Ultrasound Enhancement Of Permeable Treatment Walls, Aamod Sudhakar Sonawane

Retrospective Theses and Dissertations

The objective of this research was to demonstrate the application of ultrasound to field sites having problems with precipitation build up and corrosion. PTW s are passive reactive walls containing zero-valent iron metal for in-situ remediation of contaminated groundwater. However, loss of reactivity over time due to build up of corrosion and other precipitates on the iron surface is a major concern. Ultrasound energy has been established as an effective tool for revitalizing iron surface. This research applied ultrasound energy to a zero-valent iron wall constructed below the ground surface to remove precipitates and iron corrosion, increasing iron reactivity. Two …

Signal Integrity In Deep Submicron Cmos Chip Design, Jignesh Suresh Sonchhatra

Retrospective Theses and Dissertations

Advancement in CMOS technology has become a driving force in the advancement of today's IC design arena. In the past few years, considerable research has been done on the CMOS devices and circuits. Constant efforts have been made to realize smaller and smaller devices by reducing the channel length of the transistors and scaling down various other device parameters. Consequently, various problems have arisen such as interconnect delay, signal integrity and signal coupling.

The purpose of this thesis is to review and understand current problems in IC design and come up with various solutions to them. Efforts have been made …

Optical Performance Of Grazing Incidence X-Ray / Euv Telescopes For Space Science Applications, Patrick Louis Thompson

Retrospective Theses and Dissertations

The science and technology of X-rays has only been part of human achievement for the past 100 years, while the study of image formation in general has endured for as long as 1000 years. The ability to conceive, design, and fabricate X-ray imagers, moreover, has existed for only the past 70 years, and X-ray astronomical telescopes have been in use for a mere 35 years. Considering that aplanatic, normal incidence telescope designs required more than 400 years to perfect, it is most interesting to note that the development of ‘aplanatic’ grazing incidence telescopes has taken only about 40 years. In …
