Evaluation Of Ultrasound Method For Determining Aggregate Gradations In Asphaltic Concrete Mixes, Michael Robert Dunning

UNLV Retrospective Theses & Dissertations

The purpose of this study is to evaluate a geotechnical method, ultrasound, to detect aggregate gradation differences in asphaltic concrete pavements. Empirical data had previously been used to suggest that the more coarse the gradation, the less incidence's of rutting. It is my thesis that the more coarse the gradation, the higher the velocity of a sound wave through the asphalt concrete. This being the case, the velocity measure can be used in a design or field quality control procedure as a correlation to a performance test to choose a coarse gradation that has non-rutting field performance properties. Tests were …

The Impact Of Nonpoint Source Pollution From Mining Wastes On Water Quality, Elko County, Nevada, Samuel Earman

UNLV Retrospective Theses & Dissertations

A study was performed at a mine site in Elko County, Nevada to determine the effects on water quality resulting from waste rock at the site. Statistically significant (alpha less than or equal to 0.05) increases of several constituents, including sulfate (272 mg/L), calcium (46 mg/L), and magnesium (39 mg/L), were found to occur in the North Fork of the Humboldt River as it flows through the mine site. Geochemical modeling and historical data suggested that waste rock from the mine is primarily responsible for the increase in dissolved solids concentration. Electrical conductivity of the water exhibits seasonal fluctuations, with …

Rap Music As Protest: A Rhetorical Analysis Of Public Enemy's Lyrics, Joseph Paul Eiswerth

UNLV Retrospective Theses & Dissertations

Rap music has been one of the most popular and controversial forms of entertainment in the 1990s. Rap music serves as a form of social protest used by Blacks who feel oppressed. This study defines rap music as protest rhetoric, provides a history of rap music as an extension of Black African and American oral traditions, and analyzes the lyrics of Public Enemy, one of the most powerful protest rap artists. Although Public Enemy's music does not function in a social movement as previous protest songs, a comparison of Public Enemy's lyrics to conclusions drawn by previous researchers will show …

Examining Telecommunication Industry Efficiencies In Light Of Regulatory Reform, Robert T Flood

UNLV Retrospective Theses & Dissertations

This Thesis examines Telecommunications Industry efficiencies in the face of recent regulatory reforms; Regulation was believed to be required because of the telecommunications industry's apparent natural monopoly. The promise of regulation was to act as a surrogate to competition in controlling the monopolist. Regulation should require the monopolist to operate as close to a competitive marginal cost as possible. With effective regulation, the consumer would then expect to be paying as low a price as possible for the service provided by the regulated monopolist; Aside from commendable technological and systems improvements by the telephone companies, no significant improvement in operating …

Battle In The Skies: Sex Discrimination In The United States Airline Industry, 1930 To 1978, Cathleen M. Dooley Loucks

UNLV Retrospective Theses & Dissertations

The flight attendant occupation in the United States, developed in the 1930s, created new opportunities for women workers, but defined flight attendants as docile, temporary, and easily exploitable workers. Airlines soon discovered that flight attendants provided a marketable image, based on physical appearance. This thesis traces the development of policies, such as marriage bans, age ceilings, weight regulations, and prohibitions against pregnancy, designed to create and maintain this image. In the 1960s and 1970s, flight attendants challenged the legitimacy of these policies using the sex provision of Title VII of the Civil Rights Act of 1964. Gaining support from their …

Self-Stabilizing Tree Algorithms, Visalakshi Thiagarajan

UNLV Retrospective Theses & Dissertations

Designers of distributed algorithms have to contend with the problem of making the algorithms tolerant to several forms of coordination loss, primarily faulty initialization. The processes in a distributed system do not share a global memory and can only get a partial view of the global state. Transient failures in one part of the system may go unnoticed in other parts and thus cause the system to go into an illegal state. If the system were self-stabilizing, however, it is guaranteed that it will return to a legal state after a finite number of state transitions. This thesis presents and …

Similarity Between Polygonal Shapes, Guorong Fang

UNLV Retrospective Theses & Dissertations

In this thesis we review existing algorithms for measuring shape similarity between polygons. We present a new approach to measure similarity based on the notion of annular profile. We also present the implementation of three shape measuring algorithms: signature function, turning function, and annular profile. The implementation is done by using the Visual C++ programming language. Finally, we discuss the comparative performances of the above three methods for capturing shape similarity. Measurement of shape similarity has applications in pattern recognition and artificial intelligence.

Determination Of Soluble Mineral Content In Las Vegas Soils, Mark Alan Leonard

UNLV Retrospective Theses & Dissertations

Lower basin areas in the Las Vegas Valley contain soils with large amounts of soluble minerals. Dissolving and leaching processes due to water intrusion into foundation soils containing soluble minerals can cause a volume reduction of the soil which in turn causes structural stress. Soil improvement recommendations for soluble soils are based upon the amount of soluble minerals of a parent soil. This study reports the results of research to develop a correlation between the electrical conductivity and the concentration of soluble minerals in aqueous soil extracts. Correlations were developed by measuring the total dissolved solids and conductance of aqueous …

This thesis examines the characteristics of terrorism in the new international environment following the Cold War in which international terrorism is undergoing drastic changes in its sources and characteristics; The breakdown of the bipolar system and concomitant diffusion of political power have given way to rivalry between regional states; especially, one of the key factors is the effect of weapons proliferation on the dynamics of conflict between regional rivals including nuclear, biological, and chemical-weapons capability. The world is also confronting an assortment of prodemocracy and anti-colonial movements which tend to erupt in civil disorder. The above ingredients are currently fomenting …

Hollywood's Image Of The Working Woman, Jody Elizabeth Dawson

UNLV Retrospective Theses & Dissertations

Hollywood's Image of the Working Woman examines the stereotypes presented of working women in main stream Hollywood films. The thesis compares films portrayals of working women from "women's films" of the 1930s and 1940s with more contemporary films from the 1980s and 1990s. The paper explores the idea that there are "hegemonic processes" at work in American culture that limit the possibilities for substantive change in the way mass media portray women. This study will investigate whether these processes are at work in films which center on career-oriented female characters.

A General Approach To Boolean Function Decomposition And Its Application In Fpgabased Synthesis, Tadeusz Luba, Henry Selvaraj

Electrical & Computer Engineering Faculty Research

An effective logic synthesis procedure based on parallel and serial decomposition of a Boolean function is presented in this paper. The decomposition, carried out as the very first step of the .synthesis process, is based on an original representation of the function by a set of r-partitions over the set of minterms. Two different decomposition strategies, namely serial and parallel, are exploited by striking a balance between the two ideas. The presented procedure can be applied to completely or incompletely specified, single- or multiple-output functions and is suitable for different types of FPGAs including XILINX, ACTEL and ALGOTRONIX devices. The …

Structural Analysis Of The Hurricane Fault In The Transition Zone Between The Basin And Range Province And The Colorado Plateau, Washington County, Utah, Meg E. Schramm

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study defines fault segments and segment boundaries along the Hurricane fault in southwestern Utah and determines the geometric and kinematic relationship to other regional structures. Fault segment identification is critical for understanding fault processes and seismic risk; segment length is the maximum earthquake rupture length along a fault. Segment boundaries may act as barriers to earthquake propagation.

Normal fault segmentation only recently has received attention and has never been studied along the Hurricane fault. The fault changes strike along its length, and is thus a segmented fault. This study documents one nonconservative segment boundary and two fault segments, the …

Romancing Visual Women: From Canon To Console, Roberta Sabbath

English Faculty Research

This dissertation juxtaposes the romantic modal treatment of powerful, admired women which canonical male authors and feminist authors and critics construct with those constructed by contemporary women for the visual mass media of video, broadcast television, and computer. The discourse of the former produces the figure of a fragmented woman who is rare, supernatural, marginalized, and impossible. The discourse of the latter produces the figure of a psychologized woman who is typical, natural, mainstream, and possible. To examine the discourse of impossibility, I use three canonical works: Augustine's Confessions; Chretien de Troyes' Perceval; and Dante's Divine Comedy. I also survey …

Long-Term Effects Of Neutron Absorber And Fuel Matrix Corrosion On Criticality, William Culbreth, P. Zielinski

Mechanical Engineering Faculty Research

Proposed waste package designs will require the addition of neutron absorbing material to prevent the possibility of a sustained chain reaction occurring in the fuel in the event of water intrusion. Due to the low corrosion rates of the fuel matrix and the Zircaloy cladding, there is a possibility that the neutron absorbing material will corrode and leak from the waste container long before the subsequent release of fuel matrix material. An analysis of the release of fuel matrix and neutron absorber material based on a probabilistic model was conducted and the results were used to prepare input to KENO-V, …
