This study demonstrates the 100 g scale manufacture of a plutonium alloy that ages at an accelerated rate. The resulting alloy ages six times faster than typical weapons-grade plutonium due to the addition of 238Pu. As a major innovation, the process involved using a partial direct oxide reduction technique. This method was achieved by developing a new, complex geometry stirrer using additive manufacturing to reduce the 238Pu oxide and efficiently incorporate it into weapons-grade plutonium metal. The material was then purified by molten salt extraction and electrorefining before being alloyed with gallium. The alloy was then cold-rolled and …

The Effects Of Goal Setting On Sports Performance Of Competitive Athletes: A Meta-Analytic Review, Kelsi L. Crotts Apr 2025

The Effects Of Goal Setting On Sports Performance Of Competitive Athletes: A Meta-Analytic Review, Kelsi L. Crotts

Theses and Dissertations

Goal setting is widely used by athletes as a strategy to enhance sports performance. Despite its theoretical foundation in Goal Setting Theory (GST), empirical research has yielded mixed findings regarding its effectiveness in competitive athletic settings. Prior meta-analyses have included studies across various skill levels and motor tasks unrelated to sport, limiting their applicability to experienced athletes. The current meta-analytical review aimed to (1) evaluate the impact of goal setting on sports performance among competitive athletes, (2) examine the influence of goal characteristics such as difficulty, specificity, proximity, type, source, and feedback, and (3) identify methodological limitations in existing research …

Assessing The Impact Of Internal Flow Dynamics On Detection Region Concentrations Of Low-Cost Optical Particle Counters, Livingstone Quarshie Apr 2025

Assessing The Impact Of Internal Flow Dynamics On Detection Region Concentrations Of Low-Cost Optical Particle Counters, Livingstone Quarshie

Theses and Dissertations

Particulate matter (PM) poses significant risks to human health and the environment, making accurate measurement essential for exposure assessment and regulatory decisions. While traditional reference methods provide reliable data, they are often bulky, expensive, and difficult to maintain. Optical Particle Counters (OPCs) offer a cost-effective alternative, commonly used in clean rooms, residential spaces, and personal exposure monitoring. These devices rely on light scattering to measure PM concentrations. However, low cost OPCs face challenges related to calibration and measurement accuracy, requiring careful performance evaluation. This study used computational fluid dynamics (CFD) tools, CONVERGE Studio and ANSYS Fluent, to simulate a simplified …

The Conditioning Of Reservoir Computing And Ng-Rc For Forecasting And The Effects Of Temporal Overparameterization, Daniel Jensen Apr 2025

The Conditioning Of Reservoir Computing And Ng-Rc For Forecasting And The Effects Of Temporal Overparameterization, Daniel Jensen

Theses and Dissertations

Reservoir computing and "Next-generation reservoir computing" built on nonlinear vector autoregression are algorithms for predicting time series given past observations. Both algorithms have been successful in predicting some chaotic dynamical systems, but this success is not theoretically well understood. This paper considers the conditioning of both algorithms and the nature of the solutions found. With either algorithm, the least squares problem which is solved to give parameters as a function of the time series data is ill-conditioned, leading to parameter non-identifiability. Both algorithms fall into the class of "sloppy models." Standard practice to regularize either algorithm includes a bias towards …

Surface-Texture Fabrication Of Zirconia-Toughened Alumina Using Focused Ion-Beam Machining, Kameron M. Woodruff Apr 2025

Surface-Texture Fabrication Of Zirconia-Toughened Alumina Using Focused Ion-Beam Machining, Kameron M. Woodruff

Theses and Dissertations

Focused ion-beam machining (FIBM), a precise form of micro-machining, was tested for feasibility in the manufacturing of microscopic dimples in zirconia-toughened alumina (ZTA), a wear resistant ceramic used in artificial joint replacements. The interaction between the ion-beam and the ceramic was characterized in terms of material removal rate (MRR), surface roughness, and notable irregularities (e.g. pitting, steps at vertical faces). These characteristics were used to design and machine patterns of microscopic dimples for tribological testing. The dimple size and pattern area were limited due to a slow MRR and high cost of milling. No significant difference in the coefficient of …

"She Could Worship Now Even In The Desert": The Monastic Life As An Escape To Higher Consciousness In The Works Of Henry James, Tabetha A. Madsen Apr 2025

"She Could Worship Now Even In The Desert": The Monastic Life As An Escape To Higher Consciousness In The Works Of Henry James, Tabetha A. Madsen

Theses and Dissertations

Stephen Koch has argued that Henry James is a writer that is deeply concerned with consciousness (93). Many critics acknowledge James's attention to the metaphysical. What fewer critics have observed is that the study of the metaphysical was not simply an intellectual process for James. Instead, James's study of consciousness often reads like the private experiences of the mystic. Much of the mysticism in James's work comes from his frequent use of monastic images and values. James's use of the monastic image--characterized by the qualities of obedience, silence, celibacy, and escape--explores the limitations and possibilities of consciousness in a more …

Gnn Convergence And Accuracy Analysis On Contextual Stochastic Block Models, Trevor Garrity Apr 2025

Gnn Convergence And Accuracy Analysis On Contextual Stochastic Block Models, Trevor Garrity

Theses and Dissertations

Contextual Stochastic Block Models (cSBMs) are simple generative graph models commonly used to benchmark the performance of Graph Neural Networks (GNNs). In this thesis, I prove how inducing symmetries on general, nonlinear GNNs improves their cross entropy on cSBMs, and I derive the limiting accuracy of linear Graph Convolutional Networks (GCNs) on cSBMs. I use these results to derive the functional form of cross-entropy optimal GCNs on cSBMs and compare them to accuracy optimal GCNs.

Exploring Representations And Inductive Bias For Machine Learning Tasks In Knot Theory, Nathaniel Driggs Apr 2025

Exploring Representations And Inductive Bias For Machine Learning Tasks In Knot Theory, Nathaniel Driggs

Theses and Dissertations

Knot theory is a branch of mathematics that studies embeddings of the circle in $\mathbb{R}^3$ that are equivalent up to ambient isotopy. A link is a knot with one or more component. Knots and links have invariants, or functions from each knot to a set such as the integers or a family of polynomials. Predicting invariants can help us approximate them, understand them better, and find useful ways of representing knots and useful models for other machine learning tasks in knot theory. I perform many supervised learning experiments, predicting signature on a large, wide-ranging dataset using 5 different models and …

Power Series Rings Over Noncommutative Rings: Symmetry, Reversibility, And Semicommutativity, Nolan Ison Apr 2025

Power Series Rings Over Noncommutative Rings: Symmetry, Reversibility, And Semicommutativity, Nolan Ison

Theses and Dissertations

Let R be an associative, unital ring. One topic of interest is to assert R has some property, then determine what properties the polynomial ring R[x] and the power series ring R[[x]] are guaranteed to have. There are many relaxations of commutativity in rings. For example, a ring is said to be symmetric if abc = 0 implies acb = 0 for all a, b, c ∈ R. We discuss a certain construction of symmetric rings that we hope will yield the existence of a symmetric ring R such that the set of nilpotent elements in the power series ring …

Sample Preparation And Acquisition Strategies To Improve Accessibility And Proteome Depth In Single-Cell And Low-Input Proteomics, Sara Madisyn Johnston Apr 2025

Sample Preparation And Acquisition Strategies To Improve Accessibility And Proteome Depth In Single-Cell And Low-Input Proteomics, Sara Madisyn Johnston

Theses and Dissertations

Proteins are responsible for important cellular functions and processes including regulation, structural integrity, signaling, transport, and immune functions. Proteomics directly identifies these proteins and enables deeper characterization of the dynamic cellular environment beyond the capabilities of genomics and transcriptomics. Single-cell proteomics further enhances this approach by capturing cellular heterogeneity, which bulk proteomics obscures due to averaging protein expression across large cell populations. Despite significant advances in single-cell proteomics, continued innovation is necessary to increase workflow accessibility and throughput, minimize peptide losses, and achieve comprehensive coverage of the proteome. This dissertation addresses these challenges by developing improved sample preparation methods, two-dimensional …

Eleanor Fortescue-Brickdale And The Best, The Worst, And The Betwixt: The Intertwined Women Of Arthurian Literature And Victorian Society, Hannah Johansson Apr 2025

Eleanor Fortescue-Brickdale And The Best, The Worst, And The Betwixt: The Intertwined Women Of Arthurian Literature And Victorian Society, Hannah Johansson

Theses and Dissertations

The late Victorian and early Edwardian artist Eleanor Fortescue-Brickdale’s illustrations and paintings have been largely marginalized in the larger world of Arthurian art and criticism. This thesis argues that her work, focused on the illustration Enid, Guinevere, and Vivien, is impactful in its exploration between Arthurian characters and Victorian women. Critiquing with a feminist ideology, Brickdale attempts to break down Victorian stereotypes on women by visually breaking down the socially congruent labels placed onto the women of Camelot. In doing so, she both critiques Victorian society and artistically argues for a much needed social reconstruction.

The Semantics Of Quedar And Quedarse When Used With Adjectives Or Participles To Express A State, Charlotte Joy Peterson Apr 2025

The Semantics Of Quedar And Quedarse When Used With Adjectives Or Participles To Express A State, Charlotte Joy Peterson

Theses and Dissertations

This thesis focuses on quedar and quedarse in Spanish when used with adjectives or participles to express a state. There are four main verbs of becoming in Spanish, namely hacerse, volverse, ponerse, and quedar(se), but quedar(se) is the only verb of becoming that can be used both intransitively and pronominally to express a state. This thesis seeks to understand the relationship between adjectives and participles when used in conjunction with quedar intransitively or pronominally, and how the semantics may change based on which form is preferred. There are two largely supported claims in the literature as to when one form …

Navigating Light And Darkness: The Intersection Of Space, Faith And The Psyche In Ana Plácido’S Luz Coada Por Ferros, Alondra V. Ramirez Herrera Apr 2025

Navigating Light And Darkness: The Intersection Of Space, Faith And The Psyche In Ana Plácido’S Luz Coada Por Ferros, Alondra V. Ramirez Herrera

Theses and Dissertations

Ana Plácido (1831-1895) was a Portuguese writer whose literary contributions remain largely overshadowed by her infamous trial for adultery and her relationship with Camilo Castelo Branco. Despite societal constraints on female authorship in the nineteenth century, Plácido used literature as a means of self-expression, autonomy, and intellectual freedom. This thesis employs spatial theory to analyze her collection of texts Luz Coada por Ferros (1863), written during her imprisonment, to explore the interplay between physical confinement and artistic freedom. By examining the symbolic and psychological dimensions of space in her work, this study highlights how Plácido navigated themes of female agency, …

Non-Destructive Testing Of Stressed Materials Using X-Ray Diffraction And Second-Harmonic Generation, Melissa Nguyen Lumogdang Apr 2025

Non-Destructive Testing Of Stressed Materials Using X-Ray Diffraction And Second-Harmonic Generation, Melissa Nguyen Lumogdang

Theses and Dissertations

A material in use, anywhere from a plastic bag to common infrastructure, will eventually fail from deformation. When strained, the material chemical structure can change, and that change is dependent on many factors, including the amount of strain and strain rate. Understanding the relationship between physical properties and structural changes due to deformation can allow structural manipulation to achieve the desired physical properties. Additionally, research into non-destructive testing (NDT) methods can be used as supporting evidence for replacing destructive testing methods and possible infield stress monitoring. In this dissertation, X-ray diffraction (XRD) and second-harmonic generation (SHG) are the main NDT …

Finding Patterns In Disturbance: Modeling Ecosystem Recovery Using A Machine Learning Approach, Paden D. Allsup Apr 2025

Finding Patterns In Disturbance: Modeling Ecosystem Recovery Using A Machine Learning Approach, Paden D. Allsup

Theses and Dissertations

Some of the most visible effects of Anthropogenic climate change are shifts in resource (water) availability, and disturbance regimes across the world. Ecosystems across the world are now being forced to adapt to amplified disturbances, or in some cases, completely new disturbance types. These shifts have major implications for ecosystem stability and functioning, and more broadly for nutrient cycling across the world. In the western USA, wildfire is playing a larger and more dramatic role than before, altering vegetation communities, landscape stability, and soil and stream chemistry. While fire has always played an important role in semi-arid ecosystems, the scale …

Homomorphisms Of Peano Continua To Berbered Peano Continua, Logan Kennedy Apr 2025

Homomorphisms Of Peano Continua To Berbered Peano Continua, Logan Kennedy

Theses and Dissertations

The study of wild spaces, Peano continua that contain points that are not semi-locally simply connected, has been of integral importance in the study of low-dimensional wild topology. Mainly investigated from the view point of algebraic topology, the fundamental group has been found to be an indespensible tool in describing these spaces, and their local behavior. In particular, using methods developed by Cannon, Conner, Eda, and Kent demonstrated that all maps from Peano continua to planar or one-dimensional Peano continua are determined uniquely up to homotopy class by their induced homomorphisms on fundamental groups, and that fundamental groups are a …

I Do, And I Will: Effectual Religiosity May Strengthen The Triad Chord Of Commitment To Promote Marital Flourishing For Women Of Faith, Tamara M. Chamberlain Apr 2025

I Do, And I Will: Effectual Religiosity May Strengthen The Triad Chord Of Commitment To Promote Marital Flourishing For Women Of Faith, Tamara M. Chamberlain

Theses and Dissertations

Although religiosity often associates with marital satisfaction in sociological studies, very few studies have examined religiosity strengthening marital commitment for women of faith. This study used an exemplary sample to explore how religious, heterosexual married women view religion strengthening their marital commitment. Interviews from 196 highly religious couples provided insight into the following themes and subthemes (1) personal commitment, (a) decision to marry, (b) religious beliefs and practices, and (c) requires effort and sacrifice; (2) moral commitment, (a) sexual relations before marriage, (b) promises made before God, friends, and family, and (c) fidelity and feelings about divorce; and (3) structural …

Innovations In Sample Handling Automation To Increase Accessibility Of Sample-Limited Proteomics, Nathaniel Ben Axtell Apr 2025

Innovations In Sample Handling Automation To Increase Accessibility Of Sample-Limited Proteomics, Nathaniel Ben Axtell

Theses and Dissertations

Innovation is the vehicle that drives scientific research forward in virtually every field. Advances in genome sequencing propelled the human genome project to completion in 2003 and set the stage for the era of proteomics. Now decades of innovation in liquid chromatography (LC) and mass spectrometry (MS) have improved sensitivity sufficiently to enable single-cell proteomics and other sample-limited studies. Single-cell proteomics reveal patterns of gene expression that are often obscured by bulk-scale proteomics, leading to the identification of new protein biomarker candidates. Sensitive targeted proteomics is the key to successful translation of low-abundance protein assays into clinical applications. With a …

Effects Of Novel Fire Regimes On Plant And Animal Communities, Ryan Pienaar Apr 2025

Effects Of Novel Fire Regimes On Plant And Animal Communities, Ryan Pienaar

Theses and Dissertations

Human actions are threatening global biodiversity through changes to ecosystems to which species are not well adapted. One of the main pathways by which humans affect change is through altered disturbance regimes. This includes changes in the size, frequency, and severity of wildfires. The impact of wildfires on native plant and animal communities varies across ecosystems as species in a community have adapted relatively predictable fire patterns over time. Changing fire patterns alters successional dynamics that can favor certain species over others and thus have a negative impact on biodiversity. This dissertation evaluates responses of different plant and animal species …

Influence Of The Duchesne Fault Zone On Oil Production In The Uinta Basin, Utah, Alan Matthew Ketring Apr 2025

Influence Of The Duchesne Fault Zone On Oil Production In The Uinta Basin, Utah, Alan Matthew Ketring

Theses and Dissertations

The Duchesne Fault Zone (DFZ) is a series of east-west trending en echelon faults that developed synchronously above the neutral surface of the Duchesne Anticline during the Laramide Orogeny. The Duchesne Graben (DG) formed by decrease in displacement downward toward the neutral surface. Lake Canyon, a region that exposes the subsurface geology on the western portion of the DFZ, serves as an analog for fold formation within the saline facies of the lower Green River Formation, while Indian Canyon, an area created from the dip-slip faulting of the DG, provides clear exposures of the faulting within the sandstone-limestone facies of …

Porous Hierarchically Ordered Hydrogels Demonstrating Structurally Dependent Mechanical Properties, Elisabeth C. Lloyd, Sujata Dhakal, Shahrouz Amini, Rami Alhasan, Peter Fratzl, Douglas R. Tree, Svetlana Morozova, Robert J. Hickey Apr 2025

Porous Hierarchically Ordered Hydrogels Demonstrating Structurally Dependent Mechanical Properties, Elisabeth C. Lloyd, Sujata Dhakal, Shahrouz Amini, Rami Alhasan, Peter Fratzl, Douglas R. Tree, Svetlana Morozova, Robert J. Hickey

Faculty Publications

While hierarchical ordering is a distinctive feature of natural tissues and is directly responsible for their diverse and unique properties, efforts to synthesize biomaterials have primarily focused on using molecular-based approaches with little emphasis on multiscale structure. Here, we report a bottom-up self-assembly process to produce highly porous hydrogel fibers that resemble extracellular matrices both structurally and mechanically. Physically crosslinked nanostructured micelles form the walls of micrometer-sized water-rich pores with preferred orientation along the fiber direction. Low elastic moduli (< 1 kPa), high elasticity (extending by more than 12 times the initial length), non-linear elasticity (e.g., hyperelasticity), and completely reversible extension are derived from unevenly distributed strain between the micrometer-sized pores and the polymer chains, which is reminiscent of cellular solids. Control of the material microstructure and orientation over many orders of magnitude (e.g., nm–μm), while holding the nanostructure constant, reveals how the multiscale structure directly impacts mechanical properties.

Improving Efficiency Of Wind Flow Modeling For Wildfire Applications Using Analytical Parameterization And Neural Networks, Laura Jane Housley Apr 2025

Improving Efficiency Of Wind Flow Modeling For Wildfire Applications Using Analytical Parameterization And Neural Networks, Laura Jane Housley

Theses and Dissertations

We model wind velocity fields for applications in wildfire modeling. We improve the accuracy of the mass-conserving WindNinja solver without compromising efficient temporal complexity. We consider two approaches: the parameterization method and the neural network method. In the parameterization method, we analyze eddies in the wake of obstacles by parameterizing cavity zones as inspired by the research by Kaplan & Dinar in 1996. Kaplan & Dinar parameterize cavity zones around rectangular buildings, and we approximate a continuous landscape with rectangular buildings in order to extend this parameterization to complex terrains. In the neural network method, we train a U-net CNN …

Mythology Of Autism: Pop Culture, Rhetoric, And Vaccines, Makenzi Strate Apr 2025

Mythology Of Autism: Pop Culture, Rhetoric, And Vaccines, Makenzi Strate

Theses and Dissertations

Myths are stories told to provide an explanation for the unknown, reflect cultural beliefs of populations that hold them, and lack scientific evidence to support these stories. Some myths, such as the myth that vaccines cause autism, are harmful toward the groups that they target. Popularized in 1998 with the publication of the Wakefield study, the myth that vaccines cause autism continues to spread and thrive today. To understand the widespread nature and detriments of belief in harmful myths such as this, I implement mythology rhetoric to examine how celebrity Jenny McCarthy utilizes elements of myth to persuade others to …
