Sculpting: An Improved Inside-Out Scheme For All Hexahedral Meshing, Kirk S. Walton

Theses and Dissertations

Generating all hexahedral meshes on arbitrary geometries has been an area of important research in recent history. Hexahedral meshes have advantages over tetrahedral meshes in structural mechanics because they provide more accurate results with fewer degrees of freedom. Many different approaches have been used to create all-hexahedral meshes. Grid-based, inside-out, or superposition meshing all refer to a similar meshing approach that is a very common mesh generation technique. Grid-based algorithms provide the ability to generate all hexahedral meshes by introducing a structured mesh that bounds the complete body modeled, marking hexahedra to define an interior and exterior mesh, manipulating the …

The Enemy Within Islam, Laina Farhat-Holzman

Comparative Civilizations Review

The recent spread of political, radical Islam around the world has captured the attention of the secular world. This movement has launched a spate of violence and unrest, culminating in the al-Qaeda attack on the United States on September 11, 2001. Public interest in Islam has not been so keen since the Islamic Revolution in Iran in 1979—another event that took the world by surprise. Political observers have pinpointed the Saudis as the source of the problem. Not only were the majority of the terrorist bombers Saudi, but also they were thoroughly indoctrinated into the severe Muslim Wahhabi sect that …

An Analysis Of The Influence Of Lesson Study On Preservice Secondary Mathematics Teachers' View Of Self-As Mathematics Expert, Julie Stafford

Theses and Dissertations

This research seeks to investigate the influence of lesson study on preservice secondary mathematics teachers' view of self as mathematics expert. The study acknowledges the commonly held belief that prospective mathematics teachers have that they know and understand secondary mathematics. The purpose in engaging the preservice teachers in lesson study is to dislodge this belief. In particular, this research report focuses on one preservice teacher and her experiences during lesson study. Using the data collected, the researcher reports on the baseline beliefs that the preservice teacher held toward her knowledge of secondary mathematics, her mathematical experiences during the actual lesson …

An Approach To Concept Development For Compliant Mechanisms Possessing High Coefficients Of Restitution, Brandon H. Woolley

Theses and Dissertations

The design of structures and mechanisms subject to impact loading has historically involved designing in such a way as to minimize damage induced by the impact. This has historically been accomplished by absorbing and dissipating the energy of the impact. However, in some applications it is desirable to harness the energy and return it to the impacting object to maximize the coefficient of restitution (COR), resulting in large rebound velocities. The use of traditional rigid-body mechanisms to achieve high-COR mechanisms is limited by issues of friction, durability, poor strain-energy distribution and others. Compliant mechanisms do not possess the same limitations …

Sandwich Theorem And Calculation Of The Theta Function For Several Graphs, Marcia Ling Riddle

Theses and Dissertations

This paper includes some basic ideas about the computation of a function theta(G), the theta number of a graph G, which is known as the Lovasz number of G. theta(G^c) lies between two hard-to-compute graph numbers omega(G), the size of the largest lique in a graph G, and chi(G), the minimum number of colors need to properly color the vertices of G. Lovasz and Grotschel called this the "Sandwich Theorem". Donald E. Knuth gives four additional definitions of theta, theta_1, theta_2, theta_3, theta_4 and proves that they are all equal.

First I am going to describe the proof of the …

Channel Probing For An Indoor Wireless Communications Channel, Brandon Hunter

Theses and Dissertations

The statistics of the amplitude, time and angle of arrival of multipaths in an indoor environment are all necessary components of multipath models used to simulate the performance of spatial diversity in receive antenna configurations. The model presented by Saleh and Valenzuela, was added to by Spencer et. al., and included all three of these parameters for a 7 GHz channel. A system was built to measure these multipath parameters at 2.4 GHz for multiple locations in an indoor environment. Another system was built to measure the angle of transmission for a 6 GHz channel. The addition of this parameter …

Physical Activity And Changes In Abdominal Fat Over 18 Months: A Prospective Study Of Middle-Aged Women, Lance Eric Davidson

Theses and Dissertations

Objective: To investigate the extent to which changes in physical activity predict changes in abdominal fat in women over an 18-month period, while statistically controlling the effects of possible confounders, such as age, total body fat percent, and energy intake. Design: A prospective cohort design over 18 months. There was no intervention or treatment. Changes in objectively-measured physical activity were used to predict changes in abdominal fat over the study period. Subjects: 110 healthy, middle-aged women (mean: 41.3±3.3 yrs), primarily Caucasian, educated, and married. Measurements: An objective measure of physical activity (ACT) using CSA accelerometers, worn continuously for 7 consecutive …

On-Chip Actuation Of Compliant Bistable Micro-Mechanisms, Michael S. Baker

Theses and Dissertations

Two compliant bistable micro-mechanisms have been developed which can be switched in either direction using on-chip thermal actuation. The energy storage and bistable behavior of the mechanisms are achieved through the elastic deflection of compliant segments. The pseudo-rigid-body model was used for the compliant mechanism design, and for analysis of the large-deflection flexible segments. To achieve on-chip actuation, the mechanism designs were optimized to reduce their required rotation, allow them to be switched using linear-motion thermal actuators. The modeling theory and analysis are presented for several design iterations. Each iteration was successfully fabricated and tested using either the MUMPs or …

Thermal Microactuators For Microelectromechanical Systems (Mems), Rebecca Cragun

Theses and Dissertations

Microactuators are needed to convert energy into mechanical work at the microscale. Thermal microactuators can be used to produce this needed mechanical work. The purpose of this research was to design, fabricate, and test thermal microactuators for use at the microscale in microelectromechanical systems (MEMS). The microactuators developed were tested to determine the magnitude of their deflection and estimate their force. Five groups of thermal microactuators were designed and tested. All of the groups used the geometrically constrained expansion of various segments to produce their deflection. The first group, Thermal Expansion Devices (TEDs), produced a rotational displacement and had deflections …

An Investigation Of Compliant Over-Running Ratchet And Pawl Clutches, Gregory Mark Roach

Theses and Dissertations

This thesis proposes that compliant mechanism theory can be used to design over-running ratchet and pawl clutches with reduced part count, lower assembly and manufacturing time while maintaining functionality. An extension of the theory to the micro regime is also briefly addressed. The results of the research show that the ratchet and pawl type of over-running clutch is a good choice for the use of compliance, and the clutch pawls should be loaded in compression to get the largest amount of output torque. It was found that com-pliant mechanism theory can be used to design ratchet and pawl clutches with …

Designing, Debugging, And Deploying Configurable Computing Machine-Based Applications Using Reconfigurable Computing Application Frameworks, Anthony Lynn Slade

Theses and Dissertations

Configurable computing machines (CCMs) offer high-performance application acceleration with custom hardware. They are also dynamically reconfigurable and give significant internal visibility. Such features are useful throughout the design, debug, and deploy stages of CCM-based application development. However traditional, monolithic design tools do not offer adequate support for all of these development stages. This thesis describes a specification for a reconfigurable computing application framework (RCAF) which is more suitable for CCM application development. It also describes an implementation of such an RCAF. This RCAF improves the efficiency of application design and debugging. It also establishes an application architecture framework which helps …

Ontology-Based Extraction Of Rdf Data From The World Wide Web, Timothy Adam Chartrand

Theses and Dissertations

The simplicity and proliferation of the World Wide Web (WWW) has taken the availability of information to an unprecedented level. The next generation of the Web, the Semantic Web, seeks to make information more usable by machines by introducing a more rigorous structure based on ontologies. One hinderance to the Semantic Web is the lack of existing semantically marked-up data. Until there is a critical mass of Semantic Web data, few people will develop and use Semantic Web applications. This project helps promote the Semantic Web by providing content. We apply existing information-extraction techniques, in particular, the BYU ontologybased data-extraction …

Satisficing Applied To Simulated Soccer, Jay Packard

Theses and Dissertations

Satisficing was introduced by the economist Herbert Simon to allow for decisions that are "good enough" when there are insufficient computational resources and knowledge to obtain the optimal outcome. Autonomous multi-agent systems often require such decision making because of the complexity and unknown factors present in such an environment. Satisficing has been extended significantly by Wynn Stirling. Through extended satisficing, he has departed from conventional approaches to autonomous multi-agent systems, based as they usually are on the assumption that each participant is motivated exclusively by its own self interest, and will therefore attempt to maximize its benefit, regardless of the …

Memory-Based Tone Recognition Of Cantonese Syllables, Michael William Emonts

Theses and Dissertations

Speech recognition has only recently been applied to Cantonese. Considerable effort, however, has been spent in recognizing Mandarin, the standard dialect of Chinese. Prior to this thesis, the only published work on monosyllabic Cantonese tone recognition is from Tan Lee et al. (1993,1995). This thesis is the first of its kind in that it explores memory-based learning as a viable approach for Cantonese tone recognition. The memory-based learning algorithm employed in this thesis outperforms the highly respected and widely used neural network approach. Various numbers of tones and features are modeled to find the best method for feature selection and …

Bounding The Number Of Graphs Containing Very Long Induced Paths, Steven Kay Butler

Theses and Dissertations

Induced graphs are used to describe the structure of a graph, one such type of induced graph that has been studied are long paths.

In this thesis we show a way to represent such graphs in terms of an array with two colors and a labeled graph. Using this representation and the techniques of Polya counting we will then be able to get upper and lower bounds for graphs containing a long path as an induced subgraph.

In particular, if we let P(n,k) be the number of graphs on n+k vertices which contains P_n, a path on n vertices, as …

Time Aliasing Methods Of Spectrum Estimation, Jason F. Dahl

Theses and Dissertations

Time aliasing methods of spectrum estimation alter the time representation of a signal for the purpose of improving its frequency domain representation. Time aliasing allows characteristics of longer time window functions to be used with shorter DFT length. Windows designed specifically for use with time aliasing have improved properties compared to conventional windows. Many previous uses of time aliasing, including overlap-and-add methods of digital filtering, have focused on the elimination of time aliasing effects in the frequency domain in order to improve the representation of reconstructed signals in the time domain and have not addressed the issues associated with spectrum …

A Few Thoughts From A Believing Dna Scientist, John M. Butler

Journal of Book of Mormon Studies

The Book of Mormon does not give sufficient information about the background of Ishmael’s wife, the wives of Ishmael’s sons, and Nephi’s sisters to test the mitochondrial DNA of the group. Other problems for critics’ assertions include the uncertainty of Lehi’s possession of an Abrahamic Y chromosome and the complete disregard for the entire Jaredite population (remnants of which may have survived their final battle). Confident scientific conclusions are difficult to attain and cannot replace a spiritual witness of the truthfulness of the Book of Mormon.

Dna And The Book Of Mormon: A Phylogenetic Perspective, Michael F. Whiting

Journal of Book of Mormon Studies

This paper debunks the myth that the Book of Mormon has been proved false by modern DNA evidence. Critics have tried to apply American Indian DNA-based research to the Book of Mormon without designing a study specifically for that purpose. It is extraordinarily difficult to use DNA sequence information to track the lineage of any group with such a complex lineage history as the Nephites and Lamanites. Possible hypotheses about the populations from the Book of Mormon include the global colonization hypothesis (in which the three colonizing groups came to a land void of humans) and the local colonization hypothesis …

Tools And Metrics For Evaluating Modular Product Concepts Based On Strategic Objectives, Matthew Bailey Strong

Theses and Dissertations

The design of modular products has recently become the focus of significant research in the area of design theory and methodology. This focus is the result of increased awareness of the potential power of modularity to achieve certain product objectives. However, there continues to be a gap between the results of academic research and industrial application. The refinement, consolidation, and extension of this academic research would help design teams who are charged with developing modular products to use these academic findings in real world, industrial applications. The research presented in this document focuses on developing design tools, based on past …

Philip Morris Faces "The Truth": A Rhetorical Analysis Of The Persuasiveness Of Two Teen-Targeted Anti-Smoking Advertising Campaigns, Marybeth Mcmurray

Theses and Dissertations

This thesis examines the persuasiveness of anti-smoking television advertisements aimed at teens and produced by Philip Morris's Youth Smoking Prevention Program and the American Legacy Foundation's truth campaign. The advertisements are analyzed rhetorically using Kenneth Burke's dramatistic approach, supplemented by theory related to persuasive advertising, characteristics of at-risk adolescents, persuasive attack, and persuasive defense (apologia).

The analysis indicates that strong central themes present in both the Philip Morris and truth campaigns act as a means of rhetorical persuasion, but are not necessarily rhetoric designed to persuade adolescents not to smoke cigarettes. The truth campaign advertisements contain both strengths and weaknesses. …

Marriage Moments: A New Approach To Strengthening Couples' Relationship Through The Transition To Parenthood, Tamara Gilliland

Theses and Dissertations

Strengthening marriages is important to the well-being of individuals, families and communities. The transition to parenthood brings with it particular risks and opportunities for marriage relationships, yet no interventions have been successful in accessing a large number of couples during this critical time prepare and strengthen them for the challenges of becoming parents. The healthcare system has an established education infrastructure (childbirth education) that interacts with a significant number of couples during the transition to parenthood and has become increasingly open to incorporating relationship strengthening efforts into existing programs. The Marriage Moments program was designed to access couples through this …
