Untethered Isoperimetric Robotic Truss For Lunar Applications, Mihai Stanciu, Spencer Stowell, Isaac Weaver, Adam Rose, Chris Paul, James Wade, Ashleigh Cerven, Annie O'Bryan, Brian Bodily, Logan Yang, Nathan Usevitch

Faculty Publications

We introduce a robotic system designed to function as a lightweight, modular, and reconfigurable structure on the Moon. This robust system consists of truss-like robotic triangles, each formed by a continuous inflated fabric tube routed through two robotic roller units and a connecting unit. When deflated, these triangles can be compacted to roughly the volume of the roller units, offering an advantageous stowed-to-deployed volume ratio of 1 to 6.24. Upon inflation, the roller units pinch the tubes, creating corners by reducing the bending stiffness of the tube. Once fully deployed, electric motors move the robotic roller units along the tube, …

Improvement Of Hanford Waste Vitrification Algorithms With Machine Learning, Uncertainty Quantification, And Gradient-Based Optimization, Lagrande L. Gunnell

Theses and Dissertations

Over 200 million liters of nuclear waste is stored in tank farms in Hanford, Washington, USA. An ongoing effort to immobilize non-solid nuclear waste is through waste vitrification, where waste is mixed and melted with glass-forming chemicals (GFCs) to form a waste glass. Algorithms to determine the ideal mixing recipes are formalized as constrained optimization problems to maximize waste loading in the glass product, with constraints on several properties of the glass melt and final product. These properties are on the glass melt, such as viscosity, electrical conductivity, and corrosion rates, as well as the final glass product, such as …

Stuck In Enilikos: Growing Up In Young Adult And Middle Grade Literature, Aubrey Parry

Undergraduate Honors Theses

This thesis examines the theme of growing up in young adult and middle grade literature, specifically how various authors deal with this theme through the decisions their characters make or are given and through the actions the characters take. I’ve looked at these decisions and actions in ten popular middle grade and young adult novels, assuming that if they are popular, the middle grade and young adult readers likely have connected with something in those novels. Young adult and middle grade readers often deal with similar issues in their personal process of growing up, so many authors use their stories …

Insights Into Cortical Organization And Executive Dysfunction In Pediatric Traumatic Brain Injury, Madeleine Reading

Theses and Dissertations

Cortical gyrification is essential for cognitive development, yet its relationship with executive functioning (EF) in pediatric traumatic brain injury (TBI) remains unclear. This study examined whether children with TBI exhibit atypical cortical folding in EF-related regions and whether these differences relate to EF performance. Using FreeSurfer 7.1.1, we analyzed local gyrification index (LGI) in 206 participants (ages 5-18) from 14 sites within the ENIGMA Pediatric msTBI Working Group. Vertex-wise regression revealed that longer time since injury (TSI) was associated with increased gyrification in the right fusiform gyrus and multiple left-hemisphere regions, suggesting region-specific neuroplasticity. Contrary to expectations, higher GCS scores …

Deportations And Latino Segregation: The Residential Impacts Of Interior Immigration Enforcement, Matthew Hall, Jacob S. Rugh, Hao Liang

Faculty Publications

The shift of immigration enforcement to local jurisdictions has intensified localized patterns of anti-immigrant sentiment, enabling the system of mass deportation to expand at an unprecedented scale. This study examines the effects of 287 (g) agreements, which empower local law enforcement to enforce immigration laws, on Latino residential segregation. Using a quasi-experimental design that compares counties implementing 287 (g) with those that applied but did not implement, we find that these policies significantly slowed declines in Hispanic-white segregation, particularly in early-adopting Southern counties where enforcement was most aggressive. We find no evidence that the program altered patterns of segregation for …

Fremont Human Remains In Sevier County, Alexis Maughan

Theses and Dissertations

This study examines Fremont mortuary practices in Sevier County, Utah, through a systematic analysis of 50 individuals, recovered mainly from Late period sites. While Fremont burials are typically described as highly variable, the Sevier County sample reveals a striking pattern: approximately half of the individuals exhibit evidence of processing and were left scattered on structure floors rather than being intentionally buried. This pattern stands in contrast to the widely accepted description of Fremont burials as consisting mainly of individuals buried separately in expedient pits with minimal grave goods. The analysis draws on previously published reports, compiling the available data on …

The Effect Of Lexical Characteristics On Speech Pausing For People With Broca's Aphasia, Anna Kathryn Walker Smith

Theses and Dissertations

This study examines the connection between speech pause patterns and the lexical characteristics of the words that follow. Speech samples of 16 people with moderate Broca's aphasia and 16 age-matched neurologically healthy controls were evaluated in terms of word length, word frequency in the English language, syntactic category, and articulatory complexity. In general, people with aphasia (PWA) produced pauses more frequently before monosyllabic, very high frequency words with lower articulatory complexity, most of which were content words. The length of these pauses did not significantly correlate with any of the lexical factors examined in this study. The control group had …

Relationship Between Speaking Proficiency And Cultural Identity Of Korean Heritage Language Speakers, Minha Lee

Theses and Dissertations

Heritage language speakers from immigrant families often navigate between two languages and cultures as they form their personal identities. In this process, some develop their identity through their personal choices and external pressures, while others remain in a state of identity confusion. Although many factors contribute to the formation of their identity, the field of language education has continued to focus on the relationship between language proficiency and identity, assuming language ability could be one of the key influences. This study investigated the relationship between Korean speaking proficiency and cultural identity among Korean heritage language speakers born in the United …

Hybrid Bermudagrass Drought Tolerance In A Cool-Season Climate, Ashley J. Beazer

Theses and Dissertations

Kentucky bluegrass (Poa pratensis L.) (KBG) is the most commonly grown cool-season C3 turfgrass. However, as global temperatures rise, KBG struggles to tolerate higher temperatures, leading to increased irrigation demands--a growing concern in arid and semi-arid regions facing escalating drought conditions. In contrast, hybrid bermudagrass (HBG; Cynodon dactylon [L.] Pers. x Cynodon transvaalensis Burtt Davy), a warm-season C4 grass, has demonstrated promising adaptability in traditionally cool-season climates. Since 2008, HBG has been successfully grown with minimal winterkill in Provo, UT, USA, and is now being considered for broader adoption in similar climates. Two separate studies were conducted to evaluate the …

A Study Of The Parameters Involved In Nir Sintering Of Silver Microparticle-Based, Pad-Printed Features, Jonah Clement Brooks

Theses and Dissertations

This study explores the effectiveness of pad printing and near-infrared (NIR) sintering for producing conductive silver microparticle traces. A new pad printer was set up, and silver inks with varying concentrations of silver particles (17.5 %v/v, 20 %v/v, and 25 %v/v) were manufactured, printed, and sintered. The study identified sintering time and silver concentration as the most influential parameters affecting resistivity, with the best result of 8.73 × 10⁻⁷ Ω·m achieved using 25 %v/v ink sintered for 3 seconds at full power. Although resistivity continued to decrease at this maximum sintering duration, further optimization of parameters, including NIR bulb distance …

Examining Shifts In Reader Identity Through Explicit Fluency Instruction, Mercedes Allen

Theses and Dissertations

Fluency-a reader's ability to read accurately, with correct expression, speed, and prosody-is a main component of the science of reading (Rasinski, 2016). Although the science of reading has been a significant topic surrounding the issue of improving literacy in schools, there is little focus on the teaching of fluency at the secondary level (Shanahan, 2021; Steinle, 2022; Wexler, 2008) and how fluency influences reader identity. This article seeks to explore this question through the lens of the dialogical self (Hermans, 2001). In this case study, three 11th grade students participated in a series of lessons targeting components of fluency-accuracy, speed, …

Kissinger, D. L. Rosas, L. S. Ripplinger, E. R. Tardiff, S. L. Harris, S. Perkins, C. Hawkins, N. J. Gibbs, R. J. P. Driscoll, A. T. Sidambe, R. A. Cole, T. T. Roehling, J R. Jeffries

Faculty Publications

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

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 …

Epic Fantasy As A Postsecular Genre: The Stormlight Archive's Approach To Religion And Belief, Liz Busby

Theses and Dissertations

Epic fantasy as a genre has often been neglected due to its perceived conservative roots that clash with critical reading practices. This paper proposes that a postsecular lens may be more suitable to the critical study of epic fantasy and examines perhaps the most popular contemporary epic fantasy, Brandon Sanderson's Stormlight Archive, through a postsecular lens, First, the paper examines how the Stormlight Archive combines the premodern, fantastical worldview with modern and post-modern concerns to reinvigorate its exploration of the religious "big questions" through a renewed focus on the spiritual nature of the individual. Next, it examines how Sanderson presents …

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 …

In-Situ Void Formation During Liquid Composite Molding For Preformed Warp, Weft, And Alternating Orientation Rtm Samples, Tanner Cal Garrett

Theses and Dissertations

Carbon fiber reinforced parts are utilized by the transportation industry due to being strong yet lightweight. The highest quality parts are made using carbon fiber (CF) pre-impregnated with resin processed in an autoclave to reduce void content. The autoclave process is expensive and takes up a large amount of space, so liquid composite molding (LCM) is a less expensive alternative. The parts produced using LCM can be manufactured to rival the mechanical performance of parts made with pre-preg in an autoclave, but concerns remain over voids. Most research pertaining to void formation has been done ex-situ by either micro-CT or …

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 …

Focus On Form: Perceptions Of Portuguese Immersion Teacher When Implementing The Capa Model, Priscila Isabel Rebicki Prestes

Theses and Dissertations

This study investigates Portuguese Dual Language Immersion (DLI) teachers' perceptions when implementing the CAPA Model, a structured Focus on Form Instruction (FFI) approach aimed at improving grammatical accuracy in content-based learning. While immersion students develop strong communication skills, research highlights persistent grammatical inaccuracies due to the emphasis on meaning-based instruction. The CAPA Model seeks to bridge this gap by integrating explicit grammar instruction, fostering metalinguistic awareness, and enhancing linguistic accuracy without detracting from content learning. Findings reveal that teachers recognize the model’s benefits but face challenges such as limited planning time, a lack of pre-adapted materials, and difficulties implementing all …

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 …

Investigation Of Temperature Control's Effects In Additive Friction Stir Deposition Of Al 7050-T7451, Jason Noah Glenn

Theses and Dissertations

Additive Friction Stir Deposition (AFSD) is a friction stir based process that includes the addition of material extruding through a bore in the center of the rotating tool. The deformation of the material from the tool rotation and high pressures result in fully dense depositions printed at very high rates with forged like mechanical properties. While deposition properties of varying alloys have been increasingly published, little work has been done investigating control of the process and as with all additive processes, consistency and predictability are of significant concern before implementation can occur. One common control method implemented in Friction Stir …

The Most Beautiful Under Heaven: Selecting Views Of Modern China Through Travel Photography In Liangyou Huabao (The Young Companion), 1926-1937, Anne Marie Watson

Theses and Dissertations

Liangyou huabao (The Young Companion) was a prominent Chinese pictorial magazine, with 174 issues published monthly between 1926 and 1945. Liangyou entertained its Chinese audience with a variety of photographs documenting modern life. This thesis examines photographs of domestic travel photography in the magazine, arguing that editorial captions encouraged readers to associate images of China with allusions to traditional art and aesthetics. This occurred within a historical context where modernity was often associated with the pressures of Westernization, and where Chinese culture and civilization was sometimes characterized as outdated or irrelevant. By using travel photography to demonstrate how traditional culture …
