The Effects Of Socialization Through The Arts: Teaching Life Skills Strategies To Youth In West Las Vegas, Marcia Raquel Robinson Jan 2002

The Effects Of Socialization Through The Arts: Teaching Life Skills Strategies To Youth In West Las Vegas, Marcia Raquel Robinson

UNLV Retrospective Theses & Dissertations

There are at least 200 gangs in Southern Nevada with more than 7,700 identified members. "Gang bangers" do not anticipate a future or invest in "dreams," most do not expect to live beyond their 20's. Las Vegas is more the rule than the exception; the West Las Vegas community is the epicenter needing attention. The planning and development of this pilot program "The Performing and Visual Arts Camp for Kids" focused on teaching life skills and character development, such as getting along with others, respect for oneself and others, initiative, the ability to communicate, problem solving, perseverance, and goal setting …

A Framework For Secure Applications With Qos, Ajay Kanagala Jan 2002

A Framework For Secure Applications With Qos, Ajay Kanagala

UNLV Retrospective Theses & Dissertations

In this thesis we propose a solution to support Quality of Service (QoS) network communication transactions modeled on differentiated services and economic principles. We propose an enhanced user-level negotiation protocol where transactions are accomplished in a secure mode and where resource allocations are simple and fair. With the availability of inexpensive network monitoring hardware, any issue dealing with network security becomes a priority. Current networks must support multiple levels of service over a single network connection. Differentiated levels of service create new resource management problems for network middleware. Just as a first class passenger is willing to pay the premium …

A Noise Detection, Noise-Motion Separation And A Cancer Recognition Theory And Algorithm, Alexander Popovich Jan 2002

A Noise Detection, Noise-Motion Separation And A Cancer Recognition Theory And Algorithm, Alexander Popovich

UNLV Retrospective Theses & Dissertations

In this thesis we describe a noise detection and a motion-noise separation algorithm, as well as the stochastic properties of the noise. The difference between corresponding pixels subject to one type of noise, of two frames, has mean vector equal to (0,0,0), and variance covariance matrix with relatively small variances, for the (R, G, B) difference values. The other type of noise is a result of disturbance of the light equilibrium due to motion in neighboring or nearby pixels. In this type of noise the mean of the difference is non-zero. Every pixel not included in the one type of …

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva Jan 2002

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva

UNLV Retrospective Theses & Dissertations

This study is an attempt to apply the negotiated order perspective to the analysis of the lived experience of workers in two franchised fast food restaurants. Drawing primarily on the work of Anselm Strauss (1978) and D. H. J. Morgan (1975), I have examined data taken from auto-ethnographic and overt observation. I found that workers in different negotiation contexts would use implicit and explicit negotiation to achieve internal and external goals. Worker's negotiation strategies depended on the actor's individual proclivities and their interpretation of the negotiation context. Issues subject to negotiation included wages, the schedule, the amount of effort expended, …

The Asymptotic Behavior Of The Integer Solutions Of The Rosenberger Equations, Kensaku Umeda Jan 2002

The Asymptotic Behavior Of The Integer Solutions Of The Rosenberger Equations, Kensaku Umeda

UNLV Retrospective Theses & Dissertations

The Rosenberger equations are equations of the form: ax 2 + by2 + cz 2 = dxyz, where the sets of coefficients ( a, b, c, d) are all integers such that each of a, b, and c divides d, and the equations themselves have infinitely many integer solutions. Rosenberger has shown that there are only six such sets of coefficients, one of which is the Markoff equation, x2 + y2 + z2 = 3xyz. Zagier investigated the asymptotic behavior of the integer solutions of the Markoff equation. In this paper, we apply Zagier's techniques to the Rosenberger equations and …

From Equi-Graphical Sets To Graphical Permutations: A Problem Of Degrees In Graphs, Michael Lee Watson Jan 2002

From Equi-Graphical Sets To Graphical Permutations: A Problem Of Degrees In Graphs, Michael Lee Watson

UNLV Retrospective Theses & Dissertations

A set {a1, a2,.., an} of positive integers with a 1 < a2 < &cdots; < an is said to be equi-graphical if there exists a graph with exactly ai vertices of degree ai for each i with 1 ≤ i ≤ n. It is known that such a set is equi-graphical if and only if i=1nai is even and an≤i=1n-1 ai2 . This concept is now generalized to the following problem: Given a set S of positive integers and a permutation pi on S, determine when there exists a graph containing exactly ai vertices of degree pi(ai) for each i (1 ≤ i ≤ n). If such a graph exists, then pi is called a graphical permutation; In this paper, the graphical permutations on sets of size four are characterized and using a criterion of Fulkerson, Hoffman, and McAndrew, we show that a permutation pi of S = {a1, a2, .. , an}, where 1 ≤ a1 < a2 < &cdots; < an and such that pi(a n) = an, is graphical if and only if i=1naip ai is even and an≤i=1n-1 aipai .

Modeling Image Databases Using Xml Schema, Min Xu Jan 2002

Modeling Image Databases Using Xml Schema, Min Xu

UNLV Retrospective Theses & Dissertations

This thesis presents a model for still images in order to support content-based querying and browsing by hierarchical tree structures and object relational graphs. We use the extensible markup language (XML) schema to illustrate and exemplify the proposed model because of its interoperability and flexibility advantages. Of primary interest is the notion of complex types and referential integrity to fully describe the physical and semantic properties of images. XQuery is used to support query processing. We further show how these complex types of XML schema can be used to overcome the shortcomings of reported image database descriptions in the literature.

Representation Of Special Polynomials By The Cycle Indicator, Jack Lund Schofield Jan 2002

Representation Of Special Polynomials By The Cycle Indicator, Jack Lund Schofield

UNLV Retrospective Theses & Dissertations

Certain classes of special functions have been shown to have Cycle Indicator representations as well as recurrence relations. Most remarkably, it is shown how the Cycle Indicator can be used to unify or generalize special functions. Methods of unifying special functions are elaborated on. It follows that classical special functions with simple logarithms of their generating functions can be classified in this way. Also, there are counter-examples where the Cycle Indicator doesn't represent the special functions given; This thesis represents a study of a journal article called "Cycle Indicators and Special Functions" by Leetsch C. Hsu and Peter Jau-Shyong Shiue …

Confidence Intervals For Exposure Risk Assessment, Mark S Kirkham Jan 2002

Confidence Intervals For Exposure Risk Assessment, Mark S Kirkham

UNLV Retrospective Theses & Dissertations

The problem of estimating exposure to a pollutant involves estimation of chemical intake Q. Typically, Q has the form Q = q11q12&cdots;q 1r1/q211q22 &cdots;q2r2t where all thetaij's are unknown means of certain random variables. In assessing the risk to human health from exposure to the pollutant of concern, a confidence interval estimate of Q is needed. In the case of independent normal random variables, point estimates and certain types of interval estimates of a product of several parameters exist in the literature, but not for a ratio of products. In many situations, lot of prior knowledge is available regarding the …

Cerium And Rhodium Substitution In The Antiferromagnetic Superconductor Cerium Rhodium Indium(5), Brian Edward Light Jan 2002

Cerium And Rhodium Substitution In The Antiferromagnetic Superconductor Cerium Rhodium Indium(5), Brian Edward Light

UNLV Retrospective Theses & Dissertations

Among heavy fermion materials, a relationship between unconventional superconductivity and magnetism has been observed. The dependence of the magnetic transitions of CexLa1-xRhyIr1-y In5 with respect to temperature and magnetic field applied along the tetragonal c and a crystal axes is examined using heat capacity measurements. The magnetic phase diagram of CeRh yIrl-yIn5 for the applied transitions in the a direction shows the magnetic structure of CeRhIn5 is unchanged by Ir doping. Doping of Ir in small concentrations is shown to increase the antiferromagnetic transition temperature TN. La doping or higher concentration of Ir is shown to lower TN. This shows …

Alternate Path Routing Algorithm For Traffic Engineering In The Internet, Shyam Subramanian Jan 2002

Alternate Path Routing Algorithm For Traffic Engineering In The Internet, Shyam Subramanian

UNLV Retrospective Theses & Dissertations

Data flowing through the internet continues to grow every year. Increase in traffic demands increase in bandwidth. But bandwidth1 does not grow as fast as the traffic. This leads to congestion in the network and performance degradation. One way to avoid this problem is to use efficient routing algorithm that efficiently maps the flow of data onto the network; The most often used routing algorithm in the internet is the shortest path algorithm (Dijkstra's algorithm). This algorithm is simple and easy to implement. But this algorithm leads to over-utilization of part of the network, while the other part remains under-utilized. …

A Comparison Of Upper Confidence Limits For Skewed Distributions, Michael Gary Theemling Jan 2002

A Comparison Of Upper Confidence Limits For Skewed Distributions, Michael Gary Theemling

UNLV Retrospective Theses & Dissertations

Remediation decisions at contaminated sites are determined by comparing the Upper Confidence Limit (UCL) of the mean contaminant to a site-specific action level. The Environmental Protection Agency (EPA) has established methods for computing this UCL, also called the Exposure Point Concentration (EPC) term; The UCL formula depends upon the distribution of the contaminant concentrations, which are often positively skewed. The EPA frequently recommends the Lognormal distribution to model such data. However, that assumption often causes the UCL to be unreliable. What is the role of skewness in computing UCL statistics over different distributions? Computer simulation is used to test a …

An Analysis Of The Relationship Between Alcohol Availability And Alcohol-Related Hospital Admissions In The City Of Chicago, 1990--1997, Dorothy Ruth Wilson Jan 2002

An Analysis Of The Relationship Between Alcohol Availability And Alcohol-Related Hospital Admissions In The City Of Chicago, 1990--1997, Dorothy Ruth Wilson

UNLV Retrospective Theses & Dissertations

Current research suggested a relationship between alcohol availability and problems, including suicide, and car accidents. However, the relationship between alcohol availability and alcohol related hospital admissions, such as acute intoxication and liver damage, has not been widely explored. Measuring alcohol availability by alcohol outlet density and using data for alcohol related hospital admissions in the city of Chicago, a Poisson regression analysis determined that neighborhoods with a higher percentage of African-Americans, higher poverty level, and a greater density of alcohol outlets had a greater number of alcohol related hospital admissions than other neighborhoods. To control for individual level characteristics, a …

Partitioning A Given Circuit Targeting Multiple Fpgas, Girish Narayanan Cherussery Jan 2002

Partitioning A Given Circuit Targeting Multiple Fpgas, Girish Narayanan Cherussery

UNLV Retrospective Theses & Dissertations

Our approach to the problem of partitioning the design (represented as a hypergraph) into Multi-FPGAs uses a bi-level approach by initially clustering the design and then applying the bipartitioning technique iteratively. Each partition generated by the iterative bipartitioning technique should meet the constraints given by the FPGAs input-output and number of CLBs. The traditional FM partitioning can be applied to partition the circuit into multiple FPGAs. FM partitioning aims to minimize the number of interconnections but fails to group the nodes with maximum interconnections into one partition. Thus FM algorithm looks at the partitioning problem with a global viewpoint, abandoning …

Gender Differences In Cognitive Interference With Sexual Arousal, Sarah Elizabeth Nunnink Jan 2002

Gender Differences In Cognitive Interference With Sexual Arousal, Sarah Elizabeth Nunnink

UNLV Retrospective Theses & Dissertations

It is well documented that cognitive interference detrimentally influences sexuality, but little is known about the content of that interference. This study compared the self-reports of 220 college men and 337 college women on two types of cognitive interference during sex, performance-oriented and appearance-oriented. Also assessed via use of the Derogatis Sexual Functioning Inventory and the Sexual History Form were: sexual satisfaction, psychological distress, sexual knowledge, sexual experiences, sexual attitudes, sexual fantasy, body image, affect, and sexual functioning, all areas thought to be related to sexual functioning. As predicted, findings indicated that women were more concerned with their own appearance …

A Dynamic Simulation Model Of Beach Sand Replenishment: A Case Study Of Santa Barbara, California, David Turbow, Steve Norwick, Sajjad Ahmad Jan 2002

A Dynamic Simulation Model Of Beach Sand Replenishment: A Case Study Of Santa Barbara, California, David Turbow, Steve Norwick, Sajjad Ahmad

Civil and Environmental Engineering and Construction Faculty Research

Sediment deprivation from dam installments contributes to beach erosion yet the underlying physical and economic factors linking them together have traditionally been isolated during regional planning. In order to gain a better understanding of the behavior of a managed beach system, a dynamic simulation model was developed incorporating physical and monetary factors influencing the amount of available beach sand. The Santa Barbara littoral cell was chosen as a case study to evaluate the feasibility of beach preservation goals under scenarios in which annual sand replenishment funding, sand prices, or sediment recovery from behind dams were limiting factors to available beach …

Design And Analysis Of A Process For Melt Casting Metallic Fuel Pins Incorporating Volatile Actinides, Yitung Chen, Darrell Pepper, Randy Clarksean Jan 2002

Design And Analysis Of A Process For Melt Casting Metallic Fuel Pins Incorporating Volatile Actinides, Yitung Chen, Darrell Pepper, Randy Clarksean

Fuels Campaign (TRP)

The Transmutation Research Program requires the incorporation of non-fertile actinides into the fuel matrix for the transmuter blanket. One of three currently proposed candidate matrices for the transmuter blanket is a metallic alloy fuel matrix. Metallic fuels are an outstanding candidate for a transmutation fuel due to excellent irradiation performance and ease of fabrication. However, including a volatile constituent during fabrication of these fuel pins presents a challenge. High vapor pressure actinides, particularly americium, are susceptible to rapid vaporization and transport using traditional metal fuel casting processes. As a result, only a fraction of the desired charge is incorporated into …

The Polar Expression Of Enso And Sea-Ice Variability As Recorded In A South Pole Ice Core, Eric A. Meyerson, Paul A. Mayewski, Karl J. Kreutz, L. David Meeker, Sallie I. Whitlow, Mark S. Twickler Jan 2002

The Polar Expression Of Enso And Sea-Ice Variability As Recorded In A South Pole Ice Core, Eric A. Meyerson, Paul A. Mayewski, Karl J. Kreutz, L. David Meeker, Sallie I. Whitlow, Mark S. Twickler

Faculty Publications

An annually dated ice core recovered from South Pole (2850 m a.s.l.) in 1995, that covers the period 1487–1992, was analyzed for the marine biogenic sulfur species methanesulfonate (MS). Empirical orthogonal function analysis is used to calibrate the high-resolution MS series with associated environmental series for the period of overlap (1973–92). Utilizing this calibration we present a ~500 year long proxy record of the polar expression of the El Niño–Southern Oscillation (ENSO) and southeastern Pacific sea-ice extent variations. These records reveal short-term periods of increased (1800–50, 1900–40) and decreased sea-ice extent (1550–1610, 1660–1710, 1760–1800). In general, increased (decreased) sea-ice extent …
