Calibration And Validation Of An Ogden Material Model For Thermoplastic Polyurethane In 3d-Printed Tensegrity Structures, Caleb C. Swain

Theses and Dissertations

This work is motivated by ongoing efforts within the Smart Materials, Adaptronics, and Shock Laboratory (SMASH Lab) at Brigham Young University (BYU) to develop variable-stiffness, external fixators using 3D-printed tensegrity structures. In the process of designing and evaluating these systems, the need arose to accurately model the nonlinear mechanical behavior of thermoplastic polyurethane (TPU), the primary material used in prototype fabrication. This thesis investigates how accurately a calibrated Ogden material model can predict the nonlinear mechanical response of TPU in 3D-printed tensegrity structures. Experimental data were used to calibrate the parameters of the hyperelastic constitutive model through nonlinear optimization. An …

This study examined undergraduate students’ information-retrieval behaviors and perceptions when using ChatGPT compared to Google Search, using the technology acceptance model (TAM; Davis, 1989) extended to include trust (Gefen et al., 2003) as the guiding framework. An embedded mixed-methods design was employed, in which Likert-scale perception ratings provided a structured quantitative signal and thematic analysis of semi-structured interviews, structured information-retrieval tasks, and concurrent …

Unlocking Potential: Teachers' Perspectives On 504 Accommodations For Students With Adhd, Haley Stubbs

Theses and Dissertations

This study examined high school teachers' perspectives on the development, implementation, and effectiveness of Section 504 accommodations for students with ADHD. Five secondary teachers from a public high school participated in a focus group, and data were analyzed using inductive thematic analysis. Findings indicate that teachers report limited understanding of the 504 process, minimal involvement in eligibility decisions, and little training on how to implement accommodations. Teachers describe accommodations as vague and difficult to apply consistently within the constraints of secondary classrooms, often relying on universal classroom practices and student self-advocacy to meet student needs. Teachers also question whether accommodations …

Engineering 3d Optical Interconnects And Low-Power Radio Frequency Gaze Tracking, Blake P. Crosby

Theses and Dissertations

This thesis presents two independent research works in optical in- terconnects and radio-frequency (RF)-based gaze tracking. The first work demonstrates a silicon optical waveguide fabricated from four through-silicon vias (TSVs) produced using two-photon-absorption- assisted photo-electrochemical etching. Unlike conventional TSV fabrica- tion methods, this approach enables highly localized, non-line-of-sight etching in silicon using a focused femtosecond laser. Four approximately 5 μm diameter TSVs were etched through a 200 μm silicon wafer in a 7 μm by 7 μm pattern, leaving a central silicon region that functions as a waveguide. The fabricated structure achieved an aspect ratio of approxi- mately 40:1 with …

The Efficacy Of Open Educational Resources On Achievement Outcomes In Higher Education Institutions, Charles Trevor Alder

Theses and Dissertations

Achievement gaps remain a concern in higher education, reflected in differences in academic performance, retention, and persistence. These gaps often affect students from lower socioeconomic backgrounds and underserved populations. Open educational resources (OER) have been suggested to reduce financial barriers and support student success. This study examined whether student-level and institutional-level factors predict academic performance in a business management course using OER. Average quiz scores were collected from students across 12 higher education institutions and analyzed using hierarchical linear modeling. Colleges were included in the analysis to determine whether outcomes differed based on the proportion of minority and Pell-eligible students. …

Fear Appeal Advertising As A Tool For Preventative Medicine And Chronic Disease Mitigation, Samuel J. Moore

Undergraduate Honors Theses

Chronic disease refers broadly to a group of diseases that develop and progress as individuals age, that last 1 or more years, and that require ongoing medical attention or limit activities of daily living, or both (“About chronic diseases,” 2026). Chronic disease is most often associated with years of compounding effects of poor nutrition and physical inactivity. Since negative emotion-based advertising, also known as “fear campaigns,” have been shown to be effective forms of communication for other health related topics (Huang et al, 2017), we sought to test a fear campaign’s potential to discourage unhealthy physical activity practices in young …

Exploring The Relationship Between Body Composition, Bmi, And Sleep Outcomes Among Nepalese Brick Workers, Zoe C. Peterson

Undergraduate Honors Theses

Sleep is a critical determinant of metabolic health, with extensive evidence linking insufficient and fragmented sleep to increased adiposity and obesity risk in high-income populations. However, these relationships remain poorly understood in labor-intensive, low-income occupational settings. This study examined associations between objectively measured sleep characteristics using accelerometry and body composition among a population of Nepalese brick workers, a group of people exposed to substantial environmental and occupational stressors.

A secondary cross-sectional analysis was conducted using data from 233 adult brick workers in the Nepal Kathmandu valley. Sleep metrics – including total sleep, wake after sleep onset (WASO), and number of …

The European Union As A Blueprint: Can Its Success Guide Southern Africa’S Trade Bloc Integration?, Karen Francisca Makasi

Undergraduate Honors Theses

This thesis examines whether the European Union’s experience with regional integration can serve as a useful guide for strengthening the Southern African Development Community (SADC). While the EU is often viewed as one of the most successful models of regional cooperation, this paper argues that it should not be treated as a direct template for Southern Africa. Instead, the EU offers lessons that must be adapted to SADC’s political, economic, and institutional realities. Through comparative analysis, the thesis explores how the EU developed stronger supranational institutions, enforceable legal mechanisms, shared market rules, and funding structures that supported deeper integration among …

Theses and Dissertations

This study examined socioeconomic and language factors influencing the implementation of shared book reading behaviors following participation in caregiver-trained shared book reading workshops. While shared book reading is known to support language and literacy outcomes of children, less is known about how socioeconomic and language differences affect its implementation. Eighteen participants were recruited from a local preschool and completed a 34-question pre-survey prior to attending a 2-week shared book reading workshop, followed by a 27-question post-survey. Parents reported on literacy practices, confidence level, and shared book reading behaviors. Results indicated increased positive shared book reading behaviors and caregiver confidence following …

Using Ai To Add Tables Of Contents To Cataloging Records, Marissa Bischoff, Lance Hansen

Faculty Publications

A table of contents and summary are important metadata that improve the discoverability and description of our materials. They are optionally included in catalog records, though, because transcribing these by hand is time intensive.

We sought the most efficient way to scan and AI format the table of contents pages for inclusion in the 505 field of catalog records.  We explored different AI software, iterative prompting and the time-effectiveness of the process, in comparison to hand-typed metadata fields.

Dodosolsollalasol: Theme And Variations, Myrna J. Layton

Faculty Publications

The 2020 Korean Drama DoDoSolSolLaLaSol takes its name from, and makes substantial use of, the tune otherwise known as “Ah, vous dirai-je, Maman,” the French Folk Song whose tune Mozart used in his twelve variations, and in English as “Twinkle, Twinkle Little Star.”

The text of “Ah, vous dirai-je, Maman,” focuses on the relationship between parent and child, which is one of the thematic applications of the music in the Korean drama. However, the French children’s song’s tune is taken from an earlier French song intended for adults, “La Confidence Naïve,” which is about a romantic relationship. This is another …

"I'Ve Just Re-Read The Aeneid Again": Virgil's Thematic Influence As Depicted In Katabatic Journeys In The Fiction Of C. S. Lewis, Henry Young

Theses and Dissertations

Inspired by his studies in Classical, Medieval, and Renaissance literature, C. S. Lewis incorporated echoes of Virgil in his fiction, especially in katabatic journeys. In his scholarship, he identified Virgil's Aeneid as "secondary epic" which contains the Christian-like theme of vocation in the face of transition. Traces of this theme are evident in Lewis's fiction, expressed through mythical katabatic imagery. Katabasis, for Lewis, appears as a Pagan pattern fulfilled in Christ and experienced by His disciples through conversion. Lewis's characters, though ordinary people, must learn to accept divinely given vocations which then propel them into katabatic sequences that inspire belief …

Improving Cluster Expansion Efficiency And Generalizability, Samuel D. Bills

Undergraduate Honors Theses

The cluster expansion (CE) method is a powerful framework for modeling alloy systems by linking atomic configurations to thermophysical properties. However, constructing accurate and robust CE models requires careful selection of both training structures and cluster bases. In this work, we investigate how structure enumeration and cluster selection strategies influence CE performance in binary face-centered cubic alloys using a Julia-based implementation. Model performance is evaluated using empirical risk and the generalized aliasing decomposition (GAD), which provides insight into the relationship between model complexity and generalization error. We find that physically motivated selection strategies that prioritize small clusters consistently outperform approaches …

Design Principle For Staple-Mediated Stabilization Of Peptides And Proteins, Samantha C. Hatfield

Theses and Dissertations

Macrocyclization, or stapling, has emerged as a powerful strategy to enhance the stability and function of peptides and proteins by constraining their conformational ensembles. Stapling can improve thermodynamic stability, increase resistance to proteolytic degradation, and enhance biomolecular recognition, making it particularly valuable for the development of peptide-based therapeutics. Despite these advantages, staple design remains largely empirical, relying on iterative screening of linker chemistries, lengths, and attachment sites. This trial-and-error approach limits scalability and hinders the rational design of stabilized peptide systems. In this work, we address this challenge by integrating large-scale experimental datasets with molecular dynamic simulations to develop predictive …

Differentiation Of Self As A Therapist Effect In Couple Therapy, Nathan D. Knebel

Theses and Dissertations

Murray Bowen proposed that a therapist's level of differentiation of self influences therapeutic effectiveness, particularly in clinically distressed relational systems. Although existing literature has demonstrated that therapist effects account for a meaningful portion of variance in couple therapy outcomes, differentiation of self has received limited empirical attention as a therapist-level predictor. The present article proposes a framework for empirically examining Bowen's hypothesis by investigating whether therapist differentiation predicts trajectories of couple relationship quality across treatment. Additionally, the article explores theoretical pathways through which therapists may increase their level of differentiation, assuming Bowen's hypothesis is supported.

A Parallelized Multi-Component Radiation Testing Methodology For Systems-On-Chip, Weston M. Smith

Theses and Dissertations

As the space industry expands, there is an increased reliance on system on chip (SoC) devices in high radiation environments. The reliability of these devices becomes crucial, especially in space applications. The industry's rapid growth has led to a massive expansion in the use of Commercial Off-The-Shelf (COTS) components. Electronic systems are vulnerable to single event upsets (SEUs) and the failure modes caused by SEUs are not fully understood, especially for COTS SoCs. Standard radiation testing techniques of SEUs use a single core of a multi-core processor to monitor bit flips. In this work, we present a parallelized radiation testing …

Examining The Effects Of A Complexity-Based Treatment For One Child With Down Syndrome Using Single-Case Design, Markelle Luddington

Theses and Dissertations

Common language difficulties observed in English-speaking children with Down syndrome (DS) and developmental language disorder (DLD) include challenges with marking tense and agreement on verbs, particularly with BE verbs. In addition, difficulties with syntactic movement may further exacerbate these challenges, often resulting in increased omission errors. A complexity-based approach to treatment target selection has been suggested as one method to address these needs. Therefore, this single-case design study examined the effects of a complexity-based treatment approach for one participant with Down syndrome. Specifically, this study investigated the effects of targeting a more complex treated structure, auxiliary BE questions, and the …
