Analytical Modeling Of Wood-Frame Shear Walls And Diaphragms, Johnn Paul Judd

Theses and Dissertations

Analytical models of wood-frame shear walls and diaphragms for use in monotonic, quasi-static (cyclic), and dynamic analyses are developed in this thesis. A new analytical model is developed to accurately represent connections between sheathing panels and wood framing members (sheathing-to-framing connections) in structural analysis computer programs. This new model represents sheathing–to–framing connections using an oriented pair of nonlinear springs. Unlike previous models, the new analytical model for sheathing-to-framing connections is suitable for both monotonic, cyclic, or dynamic analyses. Moreover, the new model does not need to be scaled or adjusted. The new analytical model may be implemented in a general …

Structure From Motion Using Optical Flow Probability Distributions, Paul Clark Merrell

Theses and Dissertations

Several novel structure from motion algorithms are presented that are designed to more effectively manage the problem of noise. In many practical applications, structure from motion algorithms fail to work properly because of the noise in the optical flow values. Most structure from motion algorithms implicitly assume that the noise is identically distributed and that the noise is white. Both assumptions are false. Some points can be track more easily than others and some points can be tracked more easily in a particular direction. The accuracy of each optical flow value can be quantified using an optical flow probability distribution. …

All Hexahedral Meshing Of Multiple Source, Multiple Target, Multiple Axis Geometries Via Automatic Grafting And Sweeping, Matthew N. Earp

Theses and Dissertations

The development of algorithms for the automatic creation of finite element meshes composed entirely of hexahedra (all-hex) is an active area of research. All-hex meshes are desirable for their characteristic of high accuracy with a low node count. Sweeping is one of the most widely used algorithms for generating all-hex meshes. A limitation of sweeping, however, is that it can currently be applied only to prismatic or extruded geometry types. This thesis develops a method to combine sweeping with another algorithm known as "Grafting". Grafting adjusts the mesh on one volume to conform to a second volume. In this manner …

Phase Locked Flow Measurements Of Steady And Unsteady Vortex Generator Jets In A Separating Boundary Layer, Laura C. Hansen

Theses and Dissertations

Vortex generator jets (VGJs) have been found to be an effective method of active separation control on the suction side of a low pressure turbine (LPT) blade at low Reynolds numbers. The flow mechanisms responsible for this control were studied and documented in order to provide a basis for future improvements in LPT design. Data were collected using a stereo PIV system that enabled all three components of velocity to be measured. Steady VGJs were injected into a laminar boundary layer on a flat plate (non-separating boundary layer) in order to more fully understand the characteristics and behavior of the …

The Effects Of Fault-Induced Stress Anisotropy On Fracturing, Folding And Sill Emplacement: Insights From The Bowie Coal Mines, Southern Piceance Basin, Western Colorado., Eric Dean Robeck

Theses and Dissertations

The recognition of fault-perturbed stress fields is an important tool in areas of mineral or hydrocarbon exploration. The Bowie underground coal mines of western Colorado expose a reverse-reactivated growth fault that perturbed the stress field during cleat (fracture) formation, rotating cleat orientations up to 500 m on both sides of the fault. Two unusual fracture types are found only in coal adjacent to the fault: (1) concentric cleats, highly curved fractures that form blocks resembling balls or eggs and (2) horsetail cleats, striated surfaces that superficially resemble shattercones and result from shear failure in coal. Numerical models created with the …

Translating Huck: Difficulties In Adapting "The Adventures Of Huckleberry Finn" To Film, Bryce Moore Cundick

Theses and Dissertations

Filmmakers have had four main difficulties adapting The Adventures of Huckleberry Finn to film: point of view, structure, audience and the novel's ending. By studying the different approaches of various directors to each obstacle, certain facts emerge about both the films and the novel. While literary scholars have studied Huck from practically every angle, none have sufficiently viewed the book through the lens of adaptation, despite the fact that it has been adapted to film and television over twenty times. The few critics who have studied the adaptations have done so using dated methodologies that boil down to little more …

Mayan Metate Ethnoarchaeology, Michael T. Searcy

Theses and Dissertations

Manos and metates are ubiquitous at archaeological sites in Mesoamerica. Unfortunately, grinding stones are understudied, and thus, not much is understood about them. Understanding that archaeology is based on the use of analogy to infer past life-ways, little work has been done to create analogies specifically for manos and metates. The purpose of this thesis is to study modern grinding stones used by Mayans living in Guatemala to better understand manos and metates used by ancient peoples. I worked for two field seasons in Guatemala recording the life histories of manos and metates used by the Q'eqchi' and K'iche', two …

The Byronic Myth In Brazil: Cultural Perspectives On Lord Byron's Image In Brazilian Romanticism, Matthew Lorin Squires

Theses and Dissertations

Byron's reception in one of the nineteenth century's largest and most culturally significant post-colonial outposts, Brazil, has been virtually ignored in English studies. The implications of Lord Byron's influence in Brazil are extensive since he was overwhelmingly popular among poets but also subversive to the nationalistic aims of Brazilian Romanticism. Nearly all of the well known Brazilian Romantics were not only influenced by him, but translated him. Their notion of what it meant to be "Byronic," however, differed from ideas held in Europe. The Brazilian Byronic hero was more extreme, macabre, and sentimental, lonelier, darker, and deadlier. Byron had various …

A Tool Wear Comparative Study In Turning Versus Computer Simulation In 1018 Steel, Woodrow D. Miner

Theses and Dissertations

The material removal process uses cutting tools in order to produce the desired shape of the workpiece. Tool wear has been a problem for cutting tools, since cutting tools wear and break. Research has been accomplished in the tool wear field for tool life and more recently tool wear. The computer generation has created a method to simulate the material removal process. These computer simulations model the cutting tool reaction with the workpiece. Many of the simulation models use finite element analysis to calculate the reaction of the cutting tool. Different finite element models are being used throughout the world …

Dual-Stage Thermally Actuated Surface-Micromachined Nanopositioners, Neal B. Hubbard

The IsoPiles™ were designed to have flexural characteristics similar to steel reinforced concrete piles of equal diameter. Bending stiffness was matched based on the longitudinal members. A method for comparing transverse steel reinforcement to helical IsoTruss® members was developed, along with equations to facilitate the design of IsoTruss® structures with rounded nodes.

Compression tests were performed on 3.0 ft (0.91 m) long sections taken from …

The Relationships Among Literacy, Church Activity And Religious Orientation: A Study Of Adult Members Of The Lds Church In Utah County, Bruce R. Brewer

Theses and Dissertations

The study assessed the interplay among literacy, church activity, and religious orientation and examined the extent to which literacy predicts church activity in the presence of private religious behavior. One hundred fifty-seven subjects were administered measures of intrinsic religiousness, extrinsic religiousness, literacy levels and measures of church activity. The findings from this study suggest that literacy is related to activity, but in a way that is more complex than many investigators have considered. The results of the multiple regression analysis helped clarify the ability of literacy to predict church activity in the presence of religious orientation. Results further indicated that …

Developing A Design Space Model Using A Multidisciplinary Design Optimization Schema In A Product Lifecycle Management System To Capture Knowledge For Reuse, Nathaniel Luke Fife

Theses and Dissertations

Parametric strategies for design automation and optimization can have a big impact on engineering design. When parametric tasks and optimization frameworks and methods are combined, theses strategies can be used to make up what is known as a multidisciplinary design optimization (MDO) schema. Knowledge of a design space can be modeled by using a MDO schema to represent the design process. However, current MDO frameworks used to create this schema lack the scope to capture enterprise wide knowledge for reuse and collaboration. Concurrent with the development of MDO, many companies are moving toward increased use of product lifecycle management (PLM). …

The Effects Of Choice On Student Motivation And Physical Activity Behavior In Physical Education, Jillian Ward

Theses and Dissertations

Public school physical educators have the opportunity to help students understand the importance of engaging in regular physical activity in order to combat America's obesity problem. However, students are often unmotivated to participate in their physical education classes. Providing students with an autonomy supportive environment increases intrinsic motivation. Self-determination theory states that higher levels of intrinsic motivation should lead to an increase in behavior, or higher activity levels in a physical education class. This study examined (a) the effects of increased autonomy on self-determination, and (b) the effects of increased autonomy on physical activity levels. Seventh and eighth grade girls …

The Effects Of Direct Supervision On Therapist Behavior: A Functional Analysis, Shawn L. Thurber

Accountability For The Implementation Of Secondary Visual Arts Standards In Utah And Queensland, John K. Derby

Theses and Dissertations

Utah and the majority of states have adopted mandatory standards for visual arts, yet no accountability measures have been established. Consequently, it is impossible to determine if standards are being addressed in the art classroom and aggregate grades are subjective. Queensland, Australia instituted a system of moderated school-based assessment (moderation) in 1971, whereby assessment is accomplished locally, then verified by peer experts. Queensland ensures that standards are addressed in curricula and assessment and that exit grades are reliable and comparable. Research has shown that Utah and Queensland share comparable visual arts standards and similar demographics. Queensland moderation has been extensively …
