Quantifying Chlorophyll A Content Through Remote Sensing: A Pilot Study Of Utah Lake, Tiana Davis Mar 2006

Quantifying Chlorophyll A Content Through Remote Sensing: A Pilot Study Of Utah Lake, Tiana Davis

Theses and Dissertations

Utah Lake is a really large but shallow lake located in the arid environment of the Western United States. Due to a variety of factors it is listed by the Environmental Protection Agency as an "impaired water body" and must be closely monitored. Because of its large extent and shallow depth the water quality is heterogeneous and can change rapidly. This means that traditional water quality monitoring methods, which require large investments in field personnel, equipment, and water sample analysis, cannot produce a model that is truly representative of the entire water body. This thesis examines the feasibility of using …

Digital Storytelling: The Application Of Vichian Theory, Karen Pierotti Mar 2006

Digital Storytelling: The Application Of Vichian Theory, Karen Pierotti

Theses and Dissertations

Storytelling is often looked at as something archaic or something that simpler cultures engage in. However, in our sophisticated and highly technological world storytelling swirls about us though we may not always recognize it. This thesis looks at the phenomenon of digital storytelling that functions to create community on the Internet. In order to ground this phenomenon in theory, I examine the works of Giambattista Vico, the 18th-century Neapolitan philosopher/rhetorician, who lived on the cusp of the Renaissance and the Age of Enlightenment. Furthermore, as a teacher of rhetoric to youth, Vico admonished young people to study the arts of …

A Selective Approach To Bandwidth Overbooking, Feng Huang Mar 2006

A Selective Approach To Bandwidth Overbooking, Feng Huang

Theses and Dissertations

Overbooking is a technique used by network providers to increase bandwidth utilization. If the overbooking factor is chosen appropriately, additional virtual circuits can be admitted without degrading quality of service for existing customers. Most existing implementations use a single factor to accept a linear fraction of traffic requests. High values of this factor may cause the degradation of quality of service whereas low overbooking factors will result in underutilization of bandwidth. Network providers often select overbooking factors based only on aggregate average virtual circuit utilization. This paper proposes a selective overbooking scheme based on trunk size and usage profile. Experiments …

User Datagram Protocol With Congestion Control, Spencer L. Cox Mar 2006

User Datagram Protocol With Congestion Control, Spencer L. Cox

Theses and Dissertations

Communication through the Internet is one of the dominant methods of exchanging information. Whether at an individual or large corporate level the Internet has become essential to gathering and disseminating information. TCP and UDP are the transport layer protocols responsible for transit of nearly all Internet communications. Due to the growth of real-time audio and video applications, UDP is being used more frequently as a transport protocol. As UDP traffic increases potential problems arise. Unlike TCP, UDP has no mechanism for congestion control leading to wasted bandwidth and poor performance for other competing protocols. This thesis defines a congestion control …

Improving Steering Module Efficiency For Incremental Loading Finite Element Numeric Models, Ryan L. Kitchen Mar 2006

Improving Steering Module Efficiency For Incremental Loading Finite Element Numeric Models, Ryan L. Kitchen

Theses and Dissertations

Engineers frequently use computerized numeric models to calculate and predict water levels and current patterns for rivers, bays, and other bodies of water. This computation often involves an iterative process known as incremental loading that can cause frustration and consume a lot of time. Although the steering module in the Surface-water Modeling System (SMS) automates incremental loading to minimize user interaction, it can still be very time consuming. This thesis examines the steering module and the incremental loading process to improve its efficiency. Specifically, the RMA2 and FESWMS models are utilized. Two methods of improving efficiency are examined. The first …

Irgendwo Muss Man Doch Einmal Hingehoeren': Irmgard Keun As Heiress To The Flaneur.", Matthew D. Embley Mar 2006

Irgendwo Muss Man Doch Einmal Hingehoeren': Irmgard Keun As Heiress To The Flaneur.", Matthew D. Embley

Theses and Dissertations

Flanerie is the art of taking a walk, leisurely observing the movements and spaces of the city. By writing about cityscapes, urban realms, and the condition of society, flaneurs are able to describe the uniqueness of the metropolis and give life to the modern city—creating a photograph of an urban setting. In the early nineteenth century, and even today, flaneur literature has been ultimately dominated by men who have documented their cultural and aesthetic interactions with the city. During these times, unwritten rules have often excluded the female from participating in parts of the urban society. Today, these unwritten rules …

The Rhetoric Of Persecution: Mormon Crisis Rhetoric From 1838-1871, Zachary L. Largey Mar 2006

The Rhetoric Of Persecution: Mormon Crisis Rhetoric From 1838-1871, Zachary L. Largey

Theses and Dissertations

This study is an attempt to (1) minimize the lack of rhetorical scholarship in Mormon studies, and (2) add to the historical study of rhetoric in nineteenth-century America. Since the Mormon Church's establishment in 1830, sermons have been a vital part of the Church's development into a worldwide institution. From the simple testimonial to the more complex doctrinal explication, early Mormon leaders used the art of preaching to spread their message of God and His glories. But rarely have historians or critics focused on the rhetoric—the persuasive techniques—of these sermons. This, perhaps, stems from early Mormonism's general aversion to the …

The Acropolis At Kaminaljuyu: A Study Of Late Classic Occupation, Kelleigh Waimarie Cole Mar 2006

The Acropolis At Kaminaljuyu: A Study Of Late Classic Occupation, Kelleigh Waimarie Cole

Theses and Dissertations

The Late Classic Period at Kaminaljuyú is one of the most poorly understood periods of occupation, possibly because the artifacts and architecture lack the ornate decoration found in earlier periods. One of the largest and best preserved areas of the site is located in the Parque Arqueológico de Kaminaljuyú in Zone 7 of Guatemala City. A major focal point of architecture atKaminaljuyú is the Acropolis, which has been the focus of various excavations, particularly the work of Gustavo Espinoza from 1958 to 1962. Despite this research, much of the important documentation and artifacts recovered from these excavations have been lost. …

Learning Real-World Problems By Finding Correlated Basis Functions, Adam C. Drake Mar 2006

Learning Real-World Problems By Finding Correlated Basis Functions, Adam C. Drake

Theses and Dissertations

Learning algorithms based on the Fourier transform attempt to learn functions by approximating the largest coefficients of their Fourier representations. Nearly all previous work in Fourier-based learning has been in the theoretical realm, where properties of the transform have made it possible to prove many interesting learnability results. The real-world usefulness of Fourier-based methods, however, has not been thoroughly explored. This thesis explores methods for the practical application of Fourier-based learning. The primary contribution of this thesis is a new search algorithm for finding the largest coefficients of a function's Fourier representation. Although the search space is exponentially large, empirical …

The Portrait Of Citizen Jean-Baptiste Belley, Ex-Representative Of The Colonies By Anne-Louis Girodet Trioson: Hybridity, History Painting, And The Grand Tour, Megan Marie Collins

Theses and Dissertations

Anne-Louis Girodet Trioson's Portrait of C.[itizen] Jean-Baptiste Belley, ex-representative of the Colonies, is evidence of the changing ideological situation during the French Revolution. Girodet was one of the most learned and accomplished students of Jacques-Louis David who strove to surpass his teacher in two ways: 1) by painting David's Neoclassical style so well that his handling surpasses that of his master, and 2) by choosing subject matter never before explored by David. Girodet accomplishes both within this work. The Neoclassical handling of the image has been achieved with amazing clarity, and the central figure of an identified black man …

From Womanhood To Sisterhood: The Evolution Of The Brigham Young University Women's Conference, Velda Gale Davis Lewis Mar 2006

From Womanhood To Sisterhood: The Evolution Of The Brigham Young University Women's Conference, Velda Gale Davis Lewis

Theses and Dissertations

For over twenty-five years the Brigham Young University Women's Conference has given women in the Church of Jesus Christ of Latter-day Saints (LDS or Mormon) the opportunity to go beyond womanhood and share sisterhood. Spurred by the women's movement of the 1970s, LDS women were pressed to define for themselves what it meant to be a woman in the Church. This discovery and defining process often brought confusion, criticism and conflict. As women sought to reconcile the discrepancies between their own lives and views, their internal definition and the external definition they received from others, a reconstruction began to take …

Browser-Based Trust Negotiation, Cameron Morris Mar 2006

Browser-Based Trust Negotiation, Cameron Morris

Theses and Dissertations

Trust negotiation allows two parties on the Internet to establish trust in each other according to the digital credentials thateach other possesses. Traditionally, trust negotiation uses certificates as digital credentials. However, certificates make trust negotiation difficult to use since people rarely have certificates available to them, and they must physically possess and secure all needed certificates in order to negotiate. To avoid these problems, this thesis proposes that credential authorities negotiate on behalf of the user. This thesis defines BrowserBased Trust Negotiation (BBTN) as a method for negotiating with credential authorities using the Secure Assertion Markup Language (SAML).

Cracking And Roughness Of Asphalt Pavements Constructed Using Cement-Treated Base Materials, Jonathan Russell Hanson Mar 2006

Cracking And Roughness Of Asphalt Pavements Constructed Using Cement-Treated Base Materials, Jonathan Russell Hanson

Theses and Dissertations

While cement treatment is a proven method for improving the strength and durability of soils and aggregates, cement hydration causes shrinkage strains in the cement-treated base (CTB) that can lead to reflection cracking in asphalt surfaces. Cracking may then cause increased pavement roughness and lead to poor ride quality. The overall purpose of this research was to utilize data collected through the Long-Term Pavement Performance (LTPP) program to investigate the use and classification of CTB layers and evaluate the relative impact of cement content on the development of roughness and cracking in asphalt concrete (AC) pavements constructed using CTB layers. …

The Art And Science Of Discontinuous Innovation: A Case Study In Product Reinvention, Daniel C. Smoot Mar 2006

The Art And Science Of Discontinuous Innovation: A Case Study In Product Reinvention, Daniel C. Smoot

Theses and Dissertations

Divergence of new and old technologies is a source of tremendous innovation potential. As the dizzying pace of technological innovation accelerates indefinitely into tomorrow, not only do new paths diverge exponentially; doors already opened are increasingly abandoned for the allure of things undiscovered. Mature, late-stage life-cycle products left behind in today's fast-paced world open the floodgates to reinvention. This paper tests the hypothesis that innovativeness can be encouraged through the learning and application of universal innovation principles and processes. The implications of this research area are far-reaching. If innovation can be encouraged, then it can likely be taught. If it …

The Role Of Fgfr4 In Trigeminal Placode Cell Development, Stephanie Beth Reynolds Mar 2006

The Role Of Fgfr4 In Trigeminal Placode Cell Development, Stephanie Beth Reynolds

Theses and Dissertations

In vertebrate embryos, the ophthalmic trigeminal (opV) placode contributes sensory neurons to the trigeminal ganglion during development of the peripheral nervous system. FGFR4 is expressed transiently in the trigeminal placode as cells undergo an epithelial-mesenchymal transition and begin to migrate toward the condensing ganglion. Because of the restricted spatiotemporal expression of FGFR4 in the opV placode, it was hypothesized that FGFR4 is necessary for the process of epithelial-mesenchymal transition in the opV placode. Using electroporation, an FGFR4 inhibitory gene construct was introduced into 6—10 somite stage chick embryos. This secreted inhibitory form of the FGFR4 gene blocked endogenous FGFR4 signaling, …

The Role Of The Architect: Changes Of The Past, Practices Of The Present, And Indications Of The Future, Chad B. Jones Mar 2006

The Role Of The Architect: Changes Of The Past, Practices Of The Present, And Indications Of The Future, Chad B. Jones

Theses and Dissertations

For centuries the architect was the master builder; the one who was responsible for both the design and the construction of a project with sufficient construction expertise to oversee the project from inception to completion. Eventually, complexity of projects required a higher level of specialization leading to the separation of the designer and the builder. Since that separation, the role of the designer, or architect, has continued to shift and evolve. In recent history, the architect has been the one selected by a building owner, at the inception of the project, as the professional who is able to assist and …

Automated Manipulation For The Lotus Filament Winding Process, Jeffrey V. Anderson Mar 2006

Automated Manipulation For The Lotus Filament Winding Process, Jeffrey V. Anderson

Theses and Dissertations

The filament-winding process produces quality consistent composite parts for many industries. Filament winding allows for consistent quality parts by automating the winding process. A recent development of filament winding is the Lotus process. The Lotus process reverses conventional filament winding by leaving the mandrel stationary and winding composite fiber around the mandrel. The automated Lotus filament-winding machine is controlled by four-axis control manipulating the Lotus ring around a fixed mandrel. This allows Lotus filament winding to wind parts that do not have a linear axis. Lotus filament winding is in its early stages of development. As a second step in …
