Palladium-Imidazolium Carbene Catalyzed Heck Coupling Reactions And Synthesis Of A Novel Class Of Fluoroanthracenylmethyl Ptc Catalysts, Jiuqing Zhang Nov 2005

Palladium-Imidazolium Carbene Catalyzed Heck Coupling Reactions And Synthesis Of A Novel Class Of Fluoroanthracenylmethyl Ptc Catalysts, Jiuqing Zhang

Theses and Dissertations

Palladium catalyzed Heck coupling with aryl and alkenyl halides has become a powerful means of carbon-carbon bond formation. This standard synthetic method has been developed to a high level of utility using various catalysts, conditions and substrates. Yet significant drawbacks remain, including poor reactivity, the need for high temperatures and base, limited substrate generality, and selectivity. Mixed products often suffer from olefin migration following insertion. N-Heterocyclic carbenes (NHC) have proven to be electron-rich donors which provide higher stability and reactivity than phosphines. In a previous paper reported by our research group the imidazolium-palladium carbene has proven to be highly efficient …

Event Related Potentials: A Study Of The Processing Of Gapping Structures In Adolescents, Michelle Miller Nishida Nov 2005

Event Related Potentials: A Study Of The Processing Of Gapping Structures In Adolescents, Michelle Miller Nishida

Theses and Dissertations

Many questions remain unanswered regarding the intricacies of the human brain, especially with regard to the complexities of language processing. One essential component of human sentence processing is the ability to detect, decipher, and recover from errors in the interpretation of both verbal and written language. This process of repair of ungrammatical sentences and revision or reinterpretation of ambiguous sentences has been studied extensively in recent years. A variety of tools have been developed, including the use of event-related potentials (ERPs) in order to assess how language is processed and developed, and to help better identify the nature of these …

Real-Time Motion Transition By Example, Cameron Quinn Egbert Nov 2005

Real-Time Motion Transition By Example, Cameron Quinn Egbert

Theses and Dissertations

Motion transitioning is a common task in real-time applications such as games. While most character motions can be created a priori using motion capture or hand animation, transitions between these motions must be created by an animation system at runtime. Because of this requirement, it is often difficult to create a transition that preserves the feel that the actor or animator has put into the motion. An additional difficulty is that transitions must be created in real-time. This paper provides a method of creating motion transitions that is both computationally feasible for interactive speeds, and preserves the feel of the …

Verification Of Digital Controller Verifications, Xuan Wang Nov 2005

Verification Of Digital Controller Verifications, Xuan Wang

Theses and Dissertations

This thesis presents an analysis framework to verify the stablility property of a closed-loop control system with a software controller implementation. The usual approach to verifying stability for software uses experiments which are costly and can be dangerous. More recently, mathematical models of software have been proposed which can be used to reason about the correctness of controllers. However, these mathematical models ignore computational details that may be important in verification. We propose a method to determine the instability of a closed-loop system with a software controller implementation under l^2 inputs using simulation. This method avoids the cost of experimentation …

Evolution Of Turbine Blade Deposits In An Accelerated Deposition Facility: Roughness And Thermal Analysis, James Edward Wammack Nov 2005

Evolution Of Turbine Blade Deposits In An Accelerated Deposition Facility: Roughness And Thermal Analysis, James Edward Wammack

Theses and Dissertations

During the operation of a gas turbine, ingested contaminants present in the air form deposits on the surfaces of the turbine blades. These deposits grow over time, resulting in an increasingly rough surface. This gradual increase in roughness results in several negative consequences, among which is an increase in the rate of heat transfer to the blade which shortens blade life. This thesis presents research in which deposits were evolved on three different turbine blade coupons and their evolution was studied. A trend in roughness change over time was discovered. Also, an attempt was made to find the effect of …

Modeling Distributions Of Test Scores With Mixtures Of Beta Distributions, Jingyu Feng Nov 2005

Modeling Distributions Of Test Scores With Mixtures Of Beta Distributions, Jingyu Feng

Theses and Dissertations

Test score distributions are used to make important instructional decisions about students. The test scores usually do not follow a normal distribution. In some cases, the scores appear to follow a bimodal distribution that can be modeled with a mixture of beta distributions. This bimodality may be due different levels of students' ability. The purpose of this study was to develop and apply statistical techniques for fitting beta mixtures and detecting bimodality in test score distributions. Maximum likelihood and Bayesian methods were used to estimate the five parameters of the beta mixture distribution for scores in four quizzes in a …

An Automated Three-Dimensional Unstructured Mesh Generation Algorithm For Groundwater Modeling, James Edward Greer Nov 2005

An Automated Three-Dimensional Unstructured Mesh Generation Algorithm For Groundwater Modeling, James Edward Greer

Theses and Dissertations

This thesis describes a new method to create three-dimensional finite element meshes using the horizons to mesh algorithm. The algorithm uses available geologic data and user-defined inputs to guide the mesh generation process. This new approach allows for material layer pinch outs and many different layer refinement options to create well-formed elements that better represent hydrogeologic formations. Two case studies are presented that demonstrate the application of the algorithm's options and capabilities. A graphical interface for the algorithm was developed in the Groundwater Modeling System.

Fremont Storage And Mobility: Changing Forms Through Time, David T. Yoder Nov 2005

Fremont Storage And Mobility: Changing Forms Through Time, David T. Yoder

Theses and Dissertations

Groups of agriculturalist/hunter-gatherers known as the Fremont inhabited the eastern Great Basin and Colorado Plateau from roughly A.D. 1-A.D. 1350 (Madsen 1989). Fremont groups used differing storage strategies through time and across space. Storage strategies included on-site and off-site storage facilities which were constructed above and/or below-ground. These forms of storage occurred at different frequencies and times throughout the Fremont's 1350 year time span. Researchers (Binford 1980, 1990; Keeley 1988; Soffer 1989; Testart 1982; Wills 1992; Young 1996) using examples from various parts of the world have noted a correlation between the degree of residential mobility and the use of …

Facilitating Communication About Death Between Mothers And Adolescent Sons Using Fictional Children's Literature, Deon G. Leavy Nov 2005

Facilitating Communication About Death Between Mothers And Adolescent Sons Using Fictional Children's Literature, Deon G. Leavy

Theses and Dissertations

Most children will experience the death of a loved one in their lifetime and will need to develop healthy grieving patterns. Communication between parents and children is a key ingredient in facilitating this development. Current opinions about bibliotherapy, using a book to assist in healing, suggest that books provide understanding about grief and death and open channels of communication. Although the use of bibliotherapy is gaining popularity, little research exists about its efficacy. Utilizing the book The Bridge to Terabithia, this study evaluated the facilitation of communication about death between 19 dyads of mother and adolescent sons. Their answers and …

Grain Boundary Character Distribution In The Haz Of Friction Stir-Processed Al 7075 T7, John A. Basinger Nov 2005

Grain Boundary Character Distribution In The Haz Of Friction Stir-Processed Al 7075 T7, John A. Basinger

Theses and Dissertations

The heat affected zone (HAZ) of friction stir welded Al 7075 T7 shows diminished corrosion resistance properties when compared with the parent material. Corrosion attack in this region of the weld is primarily intergranular and is associated with the presence of precipitate free zones. Current TEM research conducted at Brigham Young University by Dr. Bin Cai finds a correlation between precipitate free zone (PFZ) width and grain boundary geometry. As both grain boundary geometry and the PFZ are associated with modes of failure in 7XXX aluminum, this paper makes a comparison of grain boundary character distributions (GBCD) in the HAZ …

Methodology For Determining The Variance Of The Taylor Factor: Application In Fe-3%Si, Craig P. Przybyla Nov 2005

Methodology For Determining The Variance Of The Taylor Factor: Application In Fe-3%Si, Craig P. Przybyla

Theses and Dissertations

The variance of the Taylor factor due to variations in the microstructure and window size is explored using both a random sampling method and a previously developed statistical relationship. The results from the random sampling method correlated well with the statistical variance relationship when the magnitude of the variance was greater than that of the numerical errors observed in the statistical calculation. An empirical relation was developed to model the results and the constants for this relationship were determined for pseudo-three dimensional Fe-3%Si. Implementation of the statistical variance relationship in true 3D microstructures is not limited by material opacity, since …

Percolation In Two-Dimensional Grain Boundary Structures And Polycrystal Property Closures, David T. Fullwood Nov 2005

Percolation In Two-Dimensional Grain Boundary Structures And Polycrystal Property Closures, David T. Fullwood

Theses and Dissertations

The thesis addresses two topics in the study of material properties as determined by the microstructure. The first topic involves percolation as a tool in relating the grain boundary structure to global properties such as fracture and corrosion resistance. The second investigates optimization techniques in order to find the space of values that properties of a material can take, from consideration of the microstructure. In part I, the applicability of standard lattice percolation models to a random 2-D grain structure is explored. A random network based on the triangle lattice is proposed as a more appropriate model, and results in …

Total Syntheses Of (+)-Geldanamycin, (-)-Ragaglitazar, And (+)-Kurasoin A And Phase-Transfer-Catalyzed Asymmetric Alkylation, Erik J. Hicken Nov 2005

Total Syntheses Of (+)-Geldanamycin, (-)-Ragaglitazar, And (+)-Kurasoin A And Phase-Transfer-Catalyzed Asymmetric Alkylation, Erik J. Hicken

Theses and Dissertations

Geldanamycin possesses various biological activities as seen in the NCI 60 cell line panel (13 nM avg., 70 nM SKBr-3 cells). The predominant mode of action providing these unique results arises from the ability of geldanamycin (GA) to bind to the chaperone heat shock protein 90 (Hsp90). Despite its complicated functionality, the first total synthesis of GA was accomplished, which included two new reactions developed specifically to address the stereochemical features. The final step in the synthesis of GA was a demethylation-oxidation sequence to generate the desired para-quinone. This step could only be accomplished with HNO3/AcOH, producing GA in …

On-Demand Tutoring In Distance Education: Intrinsically-Motivated, Scalable Interpersonal Interaction To Improve Achievement, Completion, And Satisfaction, Peter B. Williams Oct 2005

On-Demand Tutoring In Distance Education: Intrinsically-Motivated, Scalable Interpersonal Interaction To Improve Achievement, Completion, And Satisfaction, Peter B. Williams

Theses and Dissertations

The purpose of the study was to test an intrinsically-motivated interaction approach, designed to increase distance education support, for both content and motivation, in a cost-effective manner. The literature summarized shows that distance education students desire content and motivational support beyond course materials and are limited in their success without it. Further, while researchers explore increased interaction as a solution, professors usually do not have time for it and attempts to provide it are often restricted by institutions' limited resources. Very little has been published on the effects of distance education tutors and the need for more research in this …

Properties Model For Aqueous Sodium Chloride Solutions Near The Critical Point Of Water, Bing Liu Oct 2005

Properties Model For Aqueous Sodium Chloride Solutions Near The Critical Point Of Water, Bing Liu

Theses and Dissertations

Traditional excess Gibbs energy models in terms of temperature, pressure, and concentration become progressively less effective in describing the thermodynamics of aqueous solutions at temperatures above 300 ¢ªC, and are totally inadequate in the critical region of water. This deficiency is due to the strong ion association and the large property fluctuations (such as density) with small variations in pressure, temperature, and solute concentration around the critical point of water. In this work, a speciation-based model has been developed to describe the thermodynamic properties of aqueous sodium chloride solutions in the critical region of water. The anomalous fluctuation problem is …

Murals And The Development Of Merchant Activity At Chichen Itza, De Luna Lucha Aztzin Martinez Oct 2005

Murals And The Development Of Merchant Activity At Chichen Itza, De Luna Lucha Aztzin Martinez

Theses and Dissertations

The militaristic interpretations of the art of Chichen Itza, Yucatán, Mexico, fails to sufficiently describe its entire decorative program. Absent from discussions of the art tradition is the apparent focus on merchant activity in the city. The influence and power of merchants strengthened during the transition from the Classic to Postclassic in Mesoamerica. With an increase in demand of foreign goods, new exchange relationships developed between centers in Central Mexico, the Gulf, and Maya region. As a result, several cultural regions participated in a vast economic network that created political alliances and syncretic art styles. Focusing on the mural tradition …
