Cfd Analysis Of 3-D Thermalhydraulics Flow Effects On Wall Concentration Gradient Profiles For Lbe Loop Fittings, Narain Armbya

UNLV Theses, Dissertations, Professional Papers, and Capstones

The objective of the thesis is to study the effects of thermalhydraulics flows on the wall concentration gradient profiles in LBE loop fittings. To that end detailed models of the fittings have been constructed to study these effects. These fittings include sudden expansion, sudden contraction, t-joint and elbow. The typical flow rates chosen for these simulations are typical of design criteria chosen for the loop with Reynolds numbers expected around 200,000 and the usual axial temperature profiles which are being characterized in the DELTA loop at LANL. STAR-CD is the simulation package used to make these predictions, which include detailed …

Efficiency Of Taiwanese Laptop Manufacturers, Yi-Horng Lai

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Taiwanese laptop manufacturers strive hard to maintain their high growth rates and positions as leaders in the industry. Michael E. Porter claimed that Taiwanese enterprises must increase industrial efficiency to secure competitive advantage. Hence, developing an effective means of measuring and comparing the efficiency of Taiwanese laptop manufacturers is essential. Increasing the production efficiency of inefficient companies will improve the average efficiency and global competitiveness of the Taiwanese laptop industry.

This investigation examines the efficiency of 12 Taiwanese laptop manufacturers in 2002. Although financial ratio analysis represents a conventional approach to measuring the performance of enterprises using financial reports, this …

Investment And Capital Flows Under Uncertainty And Capital Market Imperfection In Oil Producing Countries, Mohamed Gaber Hassan Elsayed

Dissertations

This dissertation analyzes and estimates the interactions between domestic investment and each type of capital flow under uncertainty and capital market imperfection in 13 oil-producing countries from 1981 to 2003. First, we discuss the recent development in investment theories under uncertainty, irreversibility, and imperfect capital market. Secondly, decomposing uncertainty into permanent and transitory components--based on C-GARCH--we constructuncertainty measures of broad macroeconomic variables in addition to oil price.

Thirdly, a model of four simultaneous equations is developed to capture dynamic interactions. My contribution is twofold. First, not only do we consider the impact of uncertainty and credit market imperfection on investment, …

Phase Coherent Effects In The Speckle Correlation Of Light Scattered From Volume Disordered Media And Randomly Rough Surfaces, Bogdan Danila

Dissertations

We present a study of the statistics of the intensity patterns produced when coherent light is scattered by random media (volume disorder) or randomly rough surfaces. Such a random, granular interference pattern is called speckle. Particular emphasis is on the statistical correlations arising between thefluctuations of the intensities corresponding to distinct scattering paths; which are quantified by the speckle correlation function. In the first part, we present results for the correlation function computed for volume-disordered media by means of numerical simulation. Our focus is on the sensitivity of the correlationfunction to statistical parameters characterizing the volume distribution of the refraction …

Effectiveness Of Teaching Modalities For Pre-College Level Mathematics Courses, Dorothy Latuszek

Dissertations

College educators are challenged with providing students with choices of teaching modalities that facilitate student achievement and success at a time when students are also seeking flexible scheduling and accommodation of their differing learning styles. This is certainly the case for college students who need to demonstrate proficiency for the content in pre-college level mathematics courses prior to enrolling in college-level mathematics courses. The term "pre-college level" is defined as courses in reading, writing, and mathematics for college students lacking those skills necessary to perform college-levelcoursework at two- or four-year college institutions (Parsad & Lewis, 2003).

Do certain teaching modalities …

Teaching Fractions, Natalie Miles

Mahurin Honors College Capstone Experience/Thesis Projects

Because fractions are a vital part of mathematics instruction in schools and can be found in real life, it is important that all students understand and be able to utilize them. Teachers should choose strategies that will work best for their individual students, taking into account the various ways their students learn and the fraction knowledge students already possess. To effectively teach fractions, teachers must find ways to prompt student interest. Teachers can accomplish this through the use of technology. games. and manipulatives. Effective teachers must take into account the cultural diversity of their students. Teachers must be able to …

Divine Minds: The Cognitive Foundations Of God And Religion, Todd Tremlin

Dissertations

Understanding how human brains work bears directly on the study of religion. Introducing the new "cognitive science of religion," this dissertation explains how natural mental processes that shape everyday human thought are also responsible for the arising and persistence of religious ideas and for the content and development of religions. The central claim of this work is that understanding the origin and features of god concepts and the religious systems that form around them requires an understanding of the adapted mind. This argument unfolds in two parts. The first explores the cognitive foundations ofsupernatural beings. It discusses in both evolutionary …

A Web-Based Model Management System For Managing Biocomplexity, Kanchana Tandekar

Masters Theses & Doctoral Dissertations

Biocomplexity systems are quite complex in nature and involve nonlinear, chaotic and unpredictable behavior thus requiring highly innovative quantitative techniques in order to model their behavior. Such models are a national resource to be managed in an effort similar to the existing one for Biocomplexity data. In effect, the multidisciplinary nature of Biocomplexity research results in a need to integrate models from various disciplines and a need to exchange data and models among wide variety of users over time and space. The aim of this project is to explore a relatively new and integrated approach to managing Biocomplexity models. This …

Coordinate Conditions For A Uniformly Accelerated Or Static Plane Symmetric Metric, Preston Jones, Lucas Wanex

Publications

The coordinate conditions for three exact solutions for the metric components of a coordinate system with constant acceleration or of a static plane symmetric gravitational field are presented. First, the coordinate condition that the acceleration of light is constant is applied to the field equations to derive the metric of a coordinate system of constant acceleration. Second, the coordinate conditions required to produce the metrics of Rindler and Lass are applied to the field equations to calculate the components of these two metrics and the coordinate velocities and coordinate accelerations for light of these two metrics are compared to the …

Cases Of University Faculty Conceptions And Practices Of Teaching, Assessment And Action Research., Carol Dianne Raubenheimer 1959-

Electronic Theses and Dissertations

Conceptions of teaching and learning held by faculty in higher education broadly reflect two dominant approaches, those that are teacher-focused and content oriented, and those that are student-focused and learner oriented (Entwistle, Skinner, Entwistle & Orr, 2000). Conceptions of teaching may be reflected in the pedagogical choices and practices of instructors, but this has not been well established at college level. Thus, an examination of such conceptions may advance the understanding of good teaching at the college level (Fernandez-Balboa & Stiehl, 1995). Using a case study approach this research (a) examined conceptions of teaching and learning, assessment, and action research …

The Effect Of Rapid Maxillary Expansion On Nasal Cavity Volume And Nasal Airway Resistance, Todd Ehrler

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effects of Rapid Maxillary Expansion (RME). Using Cone Beam CT scanning technology and Rhinomanometry, the volume and nasal airway resistance (NAR) of the nasal cavity was measured immediately before and after RME.

27 subjects (16 female, and 11 male), ages 9-18 were enrolled in the study. After RME all subjects had a statistically significant increase in nasal cavity volume. The pre expansion group experienced a statistically significant reduction in NAR when compared to the post expansion group. Individuals with a high pre expansion NAR experienced the greatest reduction in NAR. The correlation between change in volume …

The Effect Of Naocl, Ca(Oh)2, Mta And Mtad On Root Dentin Fracture Resistance, Sunil Ilapogu

Loma Linda University Electronic Theses, Dissertations & Projects

Various materials are used for the treatment of immature teeth that have been subjected to trauma or decay. It is not well established what effect these materials may have on the immature root dentin. A concern would be the resistance to fracture of the remaining root dentin. The purpose of this study was to compare the resistance of fracture of bovine teeth treated with sodium hypochlorite, calcium hydroxide, gray MTA and gray MTA in conjunction with MTAD after certain periods of time. One hundred and ninety five freshly extracted, intact bovine incisors were prepared using a modified Haapasalo and Orstavik …

Cbct Panoramic Images Vs. Traditional Panoramic Radiographs, Sunny Young Hutchinson

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this research was to compare the accuracy of angular measurements of the panoramic image of the Newtom 9000™ Cone Beam Computed Tomography (CBCT) with the Sirona™ Orthophos panoramic unit. The study was separated into three parts: phantom study, patient study, and archform study. The phantom study used fabricated phantom typodonts to compare angular measurements between the Newtom 9000™ panoramic image and the Sirona™ panoramic radiograph. Accuracies of the measurements were then determined by comparing the values to the actual phantom typodont. No marked differences in angular measurements were recorded for the phantom typodont using either of the …

The Confines Of Modern Constitutionalism, David T. Butleritchie

The University of New Hampshire Law Review

[Excerpt] "Constitutionalism is an ambiguous concept, or at least the term is used in ambiguous ways. Virtually every political theorist of the modern period, certainly during the last two hundred years or more, has used the concept of a political constitution in some way or another. There is very little agreement, however, on what the term constitutionalism actually represents. Some mean it in a restrictive way, others in a more expansive way. Some use it in a proscriptive manner, while others employ it prescriptively (some, perhaps, even use it pejoratively). What nearly everyone who uses the term shares, though, is …

Parametric And Predictive Analysis Of Horizontal Well Configurations For Coalbed Methane Reservoirs In Appalachian Basin, Nikola Maricic

Graduate Theses, Dissertations, and Problem Reports (ETD)

It has been a well-established fact that the Appalachian Basin represents a high potential region for the Coalbed Methane (CBM) production. The thin coal beds in the Appalachian basin are characterized by low porosity and permeability values. Due to highly complex reservoir characteristics, different drilling techniques have been developed in order to improve ultimate gas recovery in the shortest possible time. It has been claimed that horizontal drilling is the optimum completion technique used in this region to maximize methane recovery from coalbed reservoirs.;Horizontal wells are considered to be effective in the relatively thin, naturally fractured reservoirs that are characterized …

Empirical Assessment Of Architecture-Based Reliability Of Open-Source Software, Ranganath Perugupalli

Graduate Theses, Dissertations, and Problem Reports (ETD)

A number of analytical models have been proposed earlier for quantifying software reliability. Some of these models estimate the failure behavior of the software using black-box testing, which treats the software as a monolithic whole. With the evolution of component based software development, the necessity to use white-box testing increased. A few architecture-based reliability models, which use white-box approach, were proposed earlier and they have been validated using several small case studies and proved to be correct. However, there is a dearth of large-scale empirical data used for reliability analysis. This thesis enriches the empirical knowledge in software reliability engineering. …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation describes the design, development, and flight testing of a Neural Network (NN) based Fault Tolerant Flight Control System (FTFCS) with the ability to accommodate for actuator failures. The goal of this research was to demonstrate the ability of a specific set of control laws to maintain aircraft handling qualities in the presence of failures in the actuator channels. In this study, two-failure scenarios have been investigated: aileron failure (locking of the right aileron at a trim position) and elevator failure (locking of the right elevator at a trim position). A fleet of WVU YF-22 research aircraft test-beds were …

Numerical Integration Of Linear And Nonlinear Wave Equations, Laura Lynch

Department of Mathematics: Dissertations, Theses, and Student Research

We begin our study with an analysis of various numerical methods and boundary conditions on the well-known and well-studied advection and wave equations, in particular we look at the FTCS, Lax, Lax-Wendroff, Leapfrog, and Iterated Crank Nicholson methods with periodic, outgoing, and Dirichlet boundary conditions. We will then extend our study to the nonlinear equation g_tt = g_xx – g_t²/g, introduced by Khoklov and Novikov. The nonlinearities are similar to those seen in General Relativity, and thus our analysis establishes the effects of numerical integration and boundary condition choices on the long-term stability …

Annotation Manager: An Automated Web-Based Content Management System For Digital Libraries With Annotated Bibliographies, Frenny Thomas

Theses and Dissertations

With the expansion of the World Wide Web in the 90s, individuals (especially students) are always on a quest for information resources especially in the form of Web sites. Yet many of them are overwhelmed when faced with deciding which site will best suit their research needs. As a result, these individuals may select a resource for less than optimal reasons. To ease some of the burden, libraries have made great advances to provide a place to organize information resources. Such places are called library portals, and they typically provide a gateway to web resources by categorizing and annotating them …

Fast Search For Best Representations In Multitree Dictionaries, Yan Huang, Ilya Pollak, Minh N. Do, Charles A. Bouman

Department of Electrical and Computer Engineering Technical Reports

We develop a new framework of multitree dictionaries which includes some previously proposed dictionaries as special cases. We show how to efficiently find the best object in a multitree dictionary using a recursive tree pruning algorithm. We illustrate our framework through several examples, including a novel block image coder which significantly outperforms both the standard JPEG and quadtree-based methods, and is comparable to embedded coders such as JPEG2000 and SPIHT.
