Uncertainty In Recharge From Subsidence Craters At Frenchman Flat, Nevada Test Site: Impacts Of Initial And Boundary Conditions And Media Properties, David Matthew Ely

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Nevada Test Site has over 400 subsidence craters formed by the collapse of overlying rock following underground nuclear tests. Under natural conditions, infiltration and recharge would not be considered likely due to infrequent precipitation events and extreme evapotranspiration. Crater U5a in Frenchman Flat was chosen for study because it intercepts significantly more drainage than surrounding craters. Vadose zone modeling was conducted to test the sensitivity of water movement to boundary and initial conditions. The effects of ponding depth was negligible but depth of wetting front movement was highly dependent on the lateral extent of the ponds. The model was …

Fuzzy Reliability Modeling Of Distributed Client -Server Systems, Patrick Louis Cross

Graduate Theses, Dissertations, and Problem Reports (ETD)

With the proliferation of client-server systems there is a need for new approaches to determine their reliability in the uncertain environment of the internet. The proposed methods analyze client-server reliability by accounting for uncertainties in the operational environment of the internet. The uncertainties are addressed with a fuzzy paradigm applied in a tractable, verifiable reliability model of client-server systems. For computer hardware, fuzzy sets were used to address vague reliability data using bi-state fuzzy probabilistic theories. For software and operating systems, fuzzy sets account for the uncertainties in bi-state failure data using fuzzy possibility theories. Client-server architectures, such as hypercubes, …

Engine Instrumentation And Data Analysis For Ignition System Testing, William Joseph Chambers

Graduate Theses, Dissertations, and Problem Reports (ETD)

The charge ignition system is used to ignite the fuel-air mixture in the combustion chamber of a spark ignited internal combustion engine and is the subject of many ongoing research projects. As a means to quantify the performance of an ignition system, a 16 horsepower Briggs and Stratton V-twin engine has been instrumented and the necessary data analysis software developed. This test engine was used to monitor the performance of three different ignition sources. When the performance of these ignition sources was analyzed using the test engine, the differences in performance of the systems was evident in the calculated values …

Fault-Injection Through Model Checking Via Naive Assumptions About State Machine Synchrony Semantics, Sabina Joseph

Graduate Theses, Dissertations, and Problem Reports (ETD)

Software behavior can be defined as the action or reaction of software to external and/or internal conditions. Software behavior is an important characteristic in determining software quality. Fault-injection is a method to assess software quality through its' behavior. Our research involves a fault-injection process combined with model checking. We introduce a concept of "naive assumptions" which exploits the assumptions of execution order, synchrony and fairness. "Naive assumptions" are applied to inject faults into our models. We use linear temporal logic to examine the model for anomalous behaviors. This method shows us the benefits of using fault-injection and model checking and …

Development And Validation Of A Modular Hybrid Electric Vehicle Simulation Model, William Frederick Kellermeyer Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

To attempt to bring rigor and analysis to the design process, accurate simulation programs are crucial. Most hybrid electric vehicle hybrid electric vehicle (HEV) simulation programs are written for very specific component configurations and only allow changes in component sizes. These programs prove helpful only if one designs a component configuration similar to the one already simulated. A modular based program such as the one developed here allows simpler reconfiguration of the components for an accurate simulation of almost any component configuration design. This HEV simulation program allows for simulation of all three types of hybrids, with several engine types …

Derepression Of Heterochromatin Inactivation By Induction Of A Nearby Promoter In Drosophila Melanogaster, Daniel Renick Mcneill

Graduate Theses, Dissertations, and Problem Reports (ETD)

Position-effect variegation (PEV) describes the compaction of a euchromatic gene placed next to a region of heterochromatin. This compaction into heterochromatin in some instances results in a mosaic phenotype in Drosophila melanogaster. Since its discovery in the 1930's the phenomenon of PEV has been extensively analyzed and many models describing the mechanics have been proposed. But, until recently a model system for analyzing the phenomenon at various developmental stages was not available. In 1996, Lu, Bishop, and Eissenburg were able to use a transgenic construct that variegates for both a heat shock 70 promoter-driven lacZ construct and a mini-white gene, …

Two-Stroke Linear Engine, Subhash Nandkumar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Linear, crankless, internal combustion engines may find application in the generation of electrical power without the need to convert linear to rotary motion. The elimination of the connecting rod and crankshaft can improve the efficiency of the engine significantly and the reduced weight and cost are added advantages. A linear, crankless, internal combustion engine prototype has been developed for electrical power generation in combination with a linear alternator. The operation of this engine is distinct from that of a conventional slider-crank mechanism engine, insofar as the motion of the two horizontally opposed pistons is not externally constrained. A two-stroke engine …

Nondestructive Testing Of Concrete Bridge Decks Using Ground-Penetrating Radar And The Chain Drag Method, Jerry J. Scheff

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis presents the findings of two different nondestructive techniques that are used for bridge deck analysis: the chain drag method and ground penetrating radar (GPR). The chain drag testing was performed in the laboratory with 23 simulated concrete bridge deck specimens. The specimens contained varying internal conditions such as with/without steel reinforcement and with air and water filled cracks. The tests were to determine if the chains could uncover the different characteristics of each specimen, and to see if the varying sizes of the three chains had any influence on the outcome of the results.;The GPR testing was performed …

Identification Of Math Anxiety Subtypes, Aline Elizabeth Rabalais

Graduate Theses, Dissertations, and Problem Reports (ETD)

Conceptualizations of mathematics anxiety, as well as factors that are empirically related to it, were identified from the existing literature. These factors are test, evaluation, trait, and state anxiety, as well as gender and level of math ability. Differences in these factors were hypothesized to distinguish subtypes of highly math anxious individuals from one another. In order to determine whether subtypes exist, cluster analyses were performed on a sample of 96 highly math anxious college students. The results revealed three clusters distinguished by completion time on two versions of a math test and age. Furthermore, participants' responses on a variety …

Tuple Source Relational Model: A Source-Aware Data Model For Multidatabases, Ee Peng Lim, Roger Hsiang-Li Chiang, Yinyan Cao

Research Collection School Of Computing and Information Systems

In some integration projects, complete integration of database instances may not be necessary. It may also be too costly and impossible to do so due to poor local data quality and insufficient instance-level knowledge. In this research, we study how multidatabases with global schemas should be represented and manipulated when the data instances from the local databases do not require to be fully integrated. We propose the tuple source (TS) relational model to represent multidatabases under such an integration requirement. This model extends the classical relational model by augmenting every relation with a source attribute to identify the local database …

The Integration Of Firm Resources: The Role Of Capabilities In Strategy And Firm Performance, Daniel Lynch

Graduate Theses and Dissertations

Distinctive capabilities are defined as a firm’s accumulated skills and knowledge that may lead to competitive advantage (Day 1994). Distinctive capabilities are founded upon Resource-Based Theory (Barney 1991) that focuses on internal resources as opposed to external market forces (Porter 1980). The present research discusses the integration of distinctive capabilities into this framework; that is, do certain distinctive capabilities (resources) create superior firm performance when linked to the appropriate generic business strategy?

The literature on firm performance has a rich history and is theoretically grounded in several disciplines including economics, sociology, and organizational behavior (Anderson 1982). However, there has not …

Accounting Expertise And Ill-Structured Problems: Cognitive Reasoning Abilities And Performance In Business Valuation Tasks, Wray Bradley

Graduate Theses and Dissertations

This study investigates the linkage between cognitive reasoning abilities and performance in ill-structured tasks. Prior accounting research shows that the broad construct known as general problem-solving ability is directly related to performance in ill-structured audit tasks (Libby and Tan 1994). General problem-solving ability has been defined as having sub-components comprised of verbal, quantitative, memory, and cognitive reasoning abilities (Libby 1995). Most prior accounting studies have either controlled for performance differences associated with the subcomponent abilities or have just ignored them. This has created a gap in behavioral accounting research (Shanteau 1995; Bouwman and Bradley 1997). This study seeks to partially …

Methodology And Theory Building In Mis Research, Nancy Lightner, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

This paper reports on the stage of maturity of MIS research according to the McGrath (1979) model, as evidenced by the theory building occurring in two top MIS research journals. While MIS as a discipline continues to grow, its development depends on establishing a cumulative tradition of good research (Keen 1980). Of the published papers surveyed that are relevant to theory building, 81% of them relate to theory development, while 18% address theory testing. Of the papers involving data collection, more than half use field studies as the methodology. In order to advance MIS as a mature field, it is …

Measurement Of Triple Gauge Wwγ Couplings At Lep2 Using Photonic Events, R. Barate, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

A study of events with photons and missing energy has been performed with the data sample obtained with the ALEPH detector at centre-of-mass energies from 161 to 184 GeV, corresponding to a total integrated luminosity of about 80 pb−1. The measured distributions are in agreement with Standard Model predictions, leading to constraints on WWγ gauge coupling parameters Δκγ and λγ. The results from the fit to the cross sections and to the energy and angular distributions of the photons are: Δκγ=0.05+1.15−1.10(stat)±0.25(syst), λγ=−0.05+1.55−1.45(stat)±0.30(syst).

Crisis Communication And Organizational Image: A Study Of The Nasa Challenger And Exxon Valdez, Amy O'Connor

Masters Theses

This study examines the communication activities of two crises: the NASA Challenger and Exxon Valdez and investigates the effect of accommodative and defensive statements attributable to each crisis on organizational image. The survey design queried respondents about organization image with questions about trustworthiness, responsibility and willingness for future involvement with the organization, based on statements provided. Results indicated that when organizations issue accommodative statements during a crisis, participants rated overall organizational image more positively than when defensive statements were given. Research findings are discussed based on the symbolic approach to crisis communication and the investor response theory. The implications for …

French Influences On The Historical And Nationalist Thought Of Nicolae Balcescu: An Inquiry Into The Structure Of Romanian Nationalism, Ion Matei Costinescu

Masters Theses

In the past decade nationalism has been conceptualized as a cultural artifact, a product of invention and social engineering. Yet despite the flourishing interest in questions of national identity, we still have no theory explaining the reasons why nationalism presents itself in a manifold diversity of forms and aspirations. One way of . accounting for the malleability of modern nationalism is to approach it as a product of dialectical interactions between various national ideals. In this respect, the case of Romanian nationalism is particularly instructive. Its nineteenth-century proponents consciously borrowed and adapted French cultural mores and ideological forms since they …

The Origins Of Greek Cypriot National Identity, Elena Koumna

Masters Theses

Discussions of Greek Cypriot identity have conventionally been dominated by primordial arguments, contributing to the creation and maintenance of stereotypes and mythologies about the ethnic conflict between Greek and Turkish Cypriots. In order to examine the validity of the primordial thesis, modernist and constructionist approaches on nationalism and identity are considered (Gellner 1983; Hobsbawm 1990; Anderson 1991; Hroch 1985; Smith 1991). Nationalism and identity formation are analyzed in the context of"stages," where the social composition of each stage and the degree of modernization are examined. The findings of the thesis largely support the hypotheses that pinpoint the articulation of Greek …

Online Networks In Institutions Of Higher Education: An Assessment Of Student Use, Norbaiduri Ruslan

Masters Theses

Online networks in university campuses are expected to enhance the learning process, an argument founded on the theories of Cognitive Apprenticeship, Situated Cognition, and Social Constructivism. However, the extent to which students use these networks should be a significant predictor of such benefits.

This study investigated the patterns of use of online networks in universities with a survey administered to 299 students enrolled in a random sample of undergraduate classes at Western Michigan University during the summer semester of 1998.

The findings show extensive use of email and the World Wide Web for activities that arguably benefit their education. Other …

Fitness Landscape Analysis Of Discrete Constrained Optimization Problems, Sai Prasanna Ravichandran

Masters Theses

The exponentially large size of the solution space of typical optimization problems precludes the use of any deterministic approach to search for an optimal solution. A more efficient and efficacious approach is to use heuristic algorithms based on rules of thumb to guide the search process in the solution space. Associated with every solution in the space is a real number called fitness that signifies the quality of a solution. This space and the fitness values together form the fitness landscapes. Knowledge about the topology of these fitness landscapes is vital for any heuristic search operator to expedite the search …

The Evolution Of Probability Functions In An Inelasticly Deforming Two-Phase Medium, Brent L. Adams, H. Garmestani, S. Lin

Faculty Publications

A formulation is introduced here for the evolution of correlation functions in an inelastically deforming two phase medium. Probability functions play a major role in describing the statistical distribution of different phases in a heterogeneous medium in the development of statistical continuum theory. Proper formulation of statistical continuum model for inelastic deformation requires better understanding of the evolution of the corresponding probability functions. A two point probability function representation is used to approximate the statistical correlation functions. The evolution of these functions requires the information from higher order probability functions, in this case, a three point probability function. A decomposition …
