The Effect Of Movement Velocity And Eccentric Contractions On The Bilateral Deficit, D. Clark Dickin
UNLV Retrospective Theses & Dissertations
This study was performed to examine the effects of movement velocity and eccentric contractions on the bilateral deficit. To accomplish this, 18 participants performed bilateral and unilateral contractions eccentrically and concentrically across 6 movement velocities (30, 60, 90, 120, 150, and 180{dollar}\sp\circ{dollar}/s). Repeated measures ANOVA's revealed that for both eccentric and concentric contractions, significant differences existed between bilateral and summed unilateral contractions; and at each of the six tested velocities. Further analyses revealed that the degree of the bilateral deficit increased as movement velocity increased. It is believed that the decreased tension developed during bilateral eccentric and concentric contractions, is …

Process Analysis And Simulation Of Solar Thermochemical Hydrogen Generation, Mohammad Arif Khan
UNLV Retrospective Theses & Dissertations
In this study three different kind of solar thermochemical cycles (methane reforming process, sulfur-iodine cycle and copper-chlorine cycle) have been analyzed to produce hydrogen gas. Methane reforming processes (steam methane reforming, partial oxidation and autothermal reforming) have been analyzed and simulation flowsheets have been developed. In this analysis, the temperature of all the reforming reactors are varied in the range of 500-1000 °C due to the transient nature of the solar energy. The results show that the POX reforming system is better than the other two systems for the production of the same amount of hydrogen from CH4; Process analysis …
The Silver Spring And Blackrock Faults, East-Central Nevada: Kinematics, Timing, And Role Of Low-Angle Normal Faulting In The Development Of Railroad Valley, Tyler R Knudsen
UNLV Retrospective Theses & Dissertations
The structural development of Railroad Valley, a large and economically important Tertiary basin in east-central Nevada, has been the focus of much debate. This study addresses many of the points of controversy through a detailed geologic study of structures in the southwestern White Pine Range; Detailed geologic mapping and construction of cross-sections reveal both low- and high-angle normal faults. The low-angle faults consist of three bedding-parallel faults, two top-to-the-southwest and one top-to-the-south, and two large displacement (>8 km heave) (26,000 ft) top-to-the-west detachments that denude a range-scale Mesozoic fold. Two spatially distinct groups of high-angle normal faults are present: …
Bayesian Estimation Of The Normal Mean In The Presence Of Non-Detects, Ahmed Khago
Bayesian Estimation Of The Normal Mean In The Presence Of Non-Detects, Ahmed Khago
UNLV Retrospective Theses & Dissertations
This paper is concerned with the Bayesian approach to estimate the mean when encountered with left-censored data sets. Considering the joint non-informative prior, we derived the posterior probability density function of the mean of left-censored data. However, this density function is not recognizable and we can not analytically integrate it to obtain the normalizing constant. In other words, we can not compute analytically the posterior pdf or posterior moments. Numerical integration involving the adaptive Simpson quadrature rule was used in Mat-lab to obtain the posterior mean and the upper credible limit (UCL). Several numerical examples are given which illustrate the …
Synthesizing A Piccolo Using Physical Modeling Techniques, Pamela Pnina Mandelbaum
Synthesizing A Piccolo Using Physical Modeling Techniques, Pamela Pnina Mandelbaum
UNLV Retrospective Theses & Dissertations
Physical modeling is a very affective technique used to simulate a musical instrument. It is different than most synthesizing techniques, because the synthesized sound is completely computer generated. It works by starting with a pure frequency and then applying a physical model to this signal. The physical model is created by analyzing the effects that the real instrument would have on a pure signal and then designing a model to simulate these effects using signal processing techniques; The piccolo is an instrument similar to the flute. Music synthesizers will use synthesized flute sounds for music that requires a synthesized piccolo. …

Penny Stinkards And Proper Gentlemen: The Demographics Of London's Theatre Audiences, 1567--1642, Brook Adelaide Mcginnis
UNLV Retrospective Theses & Dissertations
Knowing one's audience is crucial to any theatre. How can the marketing staff target new patrons if they know nothing about their immediate audience? This quandary need not be limited to the present. Therefore, the thesis I propose is entitled "Penny Stinkards And Proper Gentlemen: The Demographics of London's Theatre Audiences 1567-1642." I have researched the different facets of Elizabethan life that may have played a factor in attendance. Rather than discussing whom Middleton, Kyd, and Shakespeare were writing for, I have discussed who may have actually attended. Whom one writes for and who ends up in the audience are …
The Changing Dynamics Of Coattails In Senate Elections, Sheila Dubron Lambert
The Changing Dynamics Of Coattails In Senate Elections, Sheila Dubron Lambert
UNLV Retrospective Theses & Dissertations
The prevailing theoretical approach in political science has been to analyze presidential coattails from a top down perspective focusing on the effect that presidential elections have on congressional outcomes. Presidential coattail research has been limited in scope to coattails as a one-way causation often examining variables in isolation, rarely accounting for the complex nature of elections and competing forces that influence elections across various levels of campaigns. This research seeks to present a more realistic view of campaign processes by assessing the spillover effects that campaign activity for one race may have on other races occurring simultaneously. Specifically, this thesis …

Ethnic Differences Among Maltreated Youths With Respect To Posttraumatic Stress Disorder And Related Symptoms, Amie Marie Lemos-Miller
Ethnic Differences Among Maltreated Youths With Respect To Posttraumatic Stress Disorder And Related Symptoms, Amie Marie Lemos-Miller
UNLV Retrospective Theses & Dissertations
Symptoms associated with the development and maintenance of Posttraumatic Stress Disorder (PTSD) were examined in a diverse group of maltreated adolescents. The first hypothesis was that levels of PTSD symptomatology, depression, dissociation, anger, and maladaptive cognitions were expected to significantly differ among African-American, Caucasian, Hispanic, and Multiracial adolescents. The second hypothesis was that ethnicity was expected to significantly moderate a relationship between (1) severity of PTSD as measured by symptomatology, and (2) the expression of related symptoms (i.e., depression, dissociation, anger, and maladaptive cognitions). Regarding hypothesis one, African-Americans reported less depressive symptoms overall than other ethnic groups, with Caucasians and …
Gravel Ghosts: Selected Poems, Megan Ann Merchant
Gravel Ghosts: Selected Poems, Megan Ann Merchant
UNLV Retrospective Theses & Dissertations
In his collection of poetry and prose Spring and All, William Carlos Williams said, "the reader knows himself as he was twenty years ago and he has also in mind a vision of what he would be someday. Oh some day! But the thing he never knows and never dares to know is what he is at the exact moment that he is. And this moment is the only thing in which I am at all interested" (88-89). That moment is the landscape for my collected works, Gravel Ghosts. The flower itself is a great representation of the desired moment …
Gothic Analogues In Kay Boyle's Death Of A Man: Modernist Perspective And Political Reality, Cara A Minardi
Gothic Analogues In Kay Boyle's Death Of A Man: Modernist Perspective And Political Reality, Cara A Minardi
UNLV Retrospective Theses & Dissertations
In order to flesh out obscured meanings of Death of a Man, one must understand the political and social milieu between 1917-1936 in America and Europe. Incorporating a new historicist approach, this paper considers the social and political warnings contained in Boyle's Death of a Man. That American critics rejected Boyle's novel is evidence of American biases toward Europe during a period of American isolationism. The novel itself confronts European attitudes that in many cases were the result of The Treaty of Versailles and that led to World War II. Viewing Boyle's novel as a piece of Gothic writing overlaid …
Generating Quality Dominating Set, Khursheed Mohammed
Generating Quality Dominating Set, Khursheed Mohammed
UNLV Retrospective Theses & Dissertations
Construction of a small size dominating set is a well known problem in graph theory and sensor networks. A Connected dominating set (CDS) can be used as a backbone structure in sensor networks for message delivery and broadcast. The general dominating set problem is known to be NP-hard and some approximation algorithms have been proposed; In most approximation algorithms for constructing connected dominating set only the size of the dominating set has been considered. In this thesis we address the problem of constructing connected dominating sets with several quality factors that include (i) diameter, (ii) risk-factor, and (iii) interference. We …

Handwritten Number Recognition, Meenakshisundaram Murugan
UNLV Retrospective Theses & Dissertations
The main focus of this research is to automate medical form processing. An important step in this process is separating handwriting from printed text characters. We developed a filtering technique that extracts handwritten text from the printed text in the form. Once the handwritten text is segregated, each line of the segregated text is identified. The identification step is followed by character segmentation. Statistical analysis is performed on the gaps between the characters in each line. This results in a binormal curve clearly depicting two regions indicating if the gap represents the spacing between characters within a word or between …
Urvashi: A Novel, Dave Anish Mukundbhai
Urvashi: A Novel, Dave Anish Mukundbhai
UNLV Retrospective Theses & Dissertations
"Urvashi" is based on the universal theme of an obsessive love of a young man for a young woman. It's a story that's repeated in every age and culture, in the lives of countless young men and women. Porus Chaturvedi, a young "upper-caste" corporate executive in India, decides to pursue, as his "perfect match," a "lower-caste" girl (named Urvashi) not yet out of high school. Complicating this "love affair" are Porus's endless, bookish attempts to theorize life; his recruitment of a disparate band of sympathizers to act as "go betweens" and to help him "strategize"; his erotic fantasies followed by …

Joint Design For Shock Mitigation, Gopi Nallani
UNLV Retrospective Theses & Dissertations
Smart projectiles carry various electronic components that can be damaged by severe shock loads. Propagation of shock from the region of initial loading to the locations of critical components can result in their failure. The objective of the research is to mitigate (absorb/reflect/disrupt, etc.) the incident shock loading, including simulating set-back, set-forward and balloting loads on a projectile as it exits the gun muzzle and predicting the structural response of internal electronic components. A detailed finite element analysis of the projectile and internal components is presented. The effect of electronic component mounting location on peak acceleration and RMS acceleration has …
Political Factionalism Among The Mojave Indians, 1826--1875, Melinda A Oesterman
Political Factionalism Among The Mojave Indians, 1826--1875, Melinda A Oesterman
UNLV Retrospective Theses & Dissertations
The Fort Mojave Indians of California and Mohave Indians of Arizona were once united on their aboriginal territory. Their lifestyle was impacted by interaction with the Spanish, fur trappers, military explorers and emigrant parties; Spanish interaction with the Mojave in the 1600s resulted in little change. The fur trappers of the 1820s generally lacked cultural awareness and respect of Mojave resources. Military expeditions along the 35th parallel into Mojave territory were generally well received and aided by some Mojave, while other Mojave were cautious of the "foreign invaders." Emigrant parties soon followed, causing alarm among the Mojave as they believed …
Virtual Design And Modeling Of Various Manufacturing Processes For Remote Fabrication Of Transmuter Fuel, Jamil Mohamad Renno
Virtual Design And Modeling Of Various Manufacturing Processes For Remote Fabrication Of Transmuter Fuel, Jamil Mohamad Renno
UNLV Retrospective Theses & Dissertations
As currently envisioned, over 70,000 tons of high-level nuclear waste would be stored inside the planned Yucca Mountain repository. After emplacement, the site must be maintained and guarded for over 10,000 years; The reprocessing of spent nuclear fuel is a possible alternative to geological storage. Here, depleted Uranium would be separated from Plutonium and Minor Actinides. While Plutonium can be 'burned' in commercial nuclear reactors, the minor actinides would be transmuted into other elements. The large-scale deployment of remote fabrication and refabrication processes (approx. 100 tons of Minor Actinides (MA) annually) will be required. Process automation has the potential to …
"You've Got Mail": Email Use In Post-Dissolutional Relationships, Michelle P Mosbacher
"You've Got Mail": Email Use In Post-Dissolutional Relationships, Michelle P Mosbacher
UNLV Retrospective Theses & Dissertations
This study is an examination of the conscious motives involved with using email communication over face-to-face communication in post-dissolutional communication between former romantic partners. This project also answered specific questions regarding the nature of post-dissolutional communication. Data collected from 173 undergraduate students revealed that the ability to plan messages within an email is a conscious motive of using email communication that is not perceived in face-to-face communication, whereas the ability to save-face and avoid topics are not. Additionally, emoticons are sparingly used in post-dissolutional email communication, yet those participants who reported to use emoticons are also concerned with saving face. …

A Problem Concerning The Existence Of Graphs With Certain Degrees, Jonathan Seary Summer
UNLV Retrospective Theses & Dissertations
Let n ≥ 2 be a positive integer. For a sequence ( S0, S1, S 2,..Sn-1) of nonnegative integers we study the problem of whether there exists a graph there exists a graph containing i=0n-1Si vertices having exactly Si vertices whose degrees are congruent to i modulo n for each i = 0, 1, 2,.., n-1. When such a graph does exist, the sequence (S0, S 1, S2,..Sn -1) is said to be realizable. It is known for modulo 2, 3, and 4 that such a sequence is realizable with seventeen exceptions for modulo 3 and twenty-four exceptions for modulo …

Sensationalism In Local Tv News: A Content Analysis Comparing Ratings And Non-Ratings Periods, Brittany Lee Sinner
UNLV Retrospective Theses & Dissertations
Sensationalism in journalism has been a topic of debate for centuries. Many critics charge that, in general, sensationalism dominates television news over public affairs reporting. However, a gap remains in the literature regarding whether there is an increase in sensationalism during ratings periods over non-ratings periods. This study examined the amounts of sensationalism/human interest stories and local public affairs reporting during those two periods. This study examined the four major local television news stations in Las Vegas: KVBC, KVVU, KLAS, and KTNV. Eight hypotheses were tested. The hypotheses posited that when comparing ratings periods to non-ratings periods, there would be …

Peer Relations Among Female Delinquents: A Study Of Racial/Ethnic Differences And Violence, Jenna Rachael Silverman
UNLV Retrospective Theses & Dissertations
Recent increases in violence rates among female juveniles, especially African Americans and Hispanics, have necessitated an investigation of contributors to violence. The present study examines differential aspects of peer relationships as predictors of violence among female juvenile offenders, taking racial/ethnic differences into account. Questionnaires assessing for peer relationship variables (i.e., attachment, perceptions of delinquency, involvement in peer pressure, and association with delinquent peers) and delinquent and violent behavior were administered to 136 female juvenile offenders. The results showed that high levels of peer association and extrinsic rewards from peer relationships best predicted violence among female juvenile offenders. Among Caucasians, African …
