Cyclic Testing Of Special Moment Frame Connections With Buckling-Restrained Fuse Plates, Jeremiah John Merrell

Theses and Dissertations

This thesis presents the development and evaluation of a new special steel moment frame connection that employs replaceable buckling-restrained fuse plates that can enhance seismic performance and post-earthquake repairability. A total of eight unique specimens were tested on two series of beam-to-column subassemblies (W36 and W24) to investigate connection behavior under cyclic loading. The experiments examined the influence of fuse plate geometry, bolt configuration, and buckling-restraints on strength, ductility, and deformation capacity. Results indicated that the buckling-restraint washers and bolts were effective at preventing out-of-plane buckling. Specimen M1.5 was successful in meeting the AISC 341-22 qualifications requirements for special moment …

Validation Of A Mesh-Based Computational Fluid Dynamics Model, The Generataion Of Reference Wake Mixing Data, And A Preliminary Comparison To A Lagrangian Vortex Based Model, Justin Don Hawkins

Theses and Dissertations

Three things are accomplished in this work. First, a verified wind turbine model is developed for both turbulent and non-turbulent flows. The verified model is created using AMR-Wind, a mesh-based CFD solver which uses an actuator line model to represent the turbine blades. Second, a database of turbine forces and wake data is compiled using the verified wake model. This data is collected for simulations of two turbines operating in close proximity to one another in various configurations. When the wake of one turbine interacts with another, wake mixing occurs. Wake mixing affects turbine performance and is important for predicting …

Utah Lake From Space: Analysis Of Sentinel 2 And Modis Data Shows Spatiotemporal Trends And Patterns In Chlorophyll-A, Turbidity, And Temperature, Kaylee Brook Tanner

Theses and Dissertations

Harmful algal blooms (HABs) are a serious and growing risk to waterbodies around the world. Excessive algal growth, especially when it involves cyanobacteria, impairs the functioning of aquatic ecosystems and threatens the health of humans and animals using the water. There is currently great interest in developing effective prevention and mitigation strategies for these blooms, particularly in ecologically and economically vital freshwater lakes. Such development, however, requires detailed understanding of HAB drivers and dynamics, which can be highly complex and difficult to characterize. High-frequency, high-resolution imagery from earth observation satellites provides spatially and temporally comprehensive data on global lakes--data which …

Snow Surfacing Optimized For An Animated Short Film Pipeline, Kristen Whitehouse

Undergraduate Honors Theses

Love and Gold is the BYU Center for Animation’s 2025 senior capstone short film. This ambitious film is the longest produced in the history of the animation program. It’s a love story that takes place in at least five different large environment sets. Two of these sets contain snow. This creative thesis tackles the problem of surfacing the snow within that context.

Surfacing snow required research and development of a snow generator for adding new geometry on top of objects in a scene and a snow shader to make that geometry appear like snow in the final render. Packaging the …

Listening To Life In A Noisy World: The Pitfalls And Promise Of Urban Acoustic Ecology, Leah O'Barr

Undergraduate Honors Theses

This thesis examines the application of soundscape ecology principles to urban settings. Soundscape ecology is the study of the entire sonic makeup of a community, composed of biophony (biological sound), geophony (environmental sound), and anthrophony (human-generated sound). By examining the changes in and qualities of the soundscape, researchers can gain information about the biological makeup and ecological quality of an area, and the temporal and spatial distribution of resident species. Recent technological advances in recording equipment and machine learning methods are making soundscape ecology an increasingly relevant and practical tool.

Applying soundscape ecology methods to urban ecosystems introduces unique challenges, …

Inelastic Behavior Of Three-Story Buildings With Concrete-Filled Composite Plate Shear Walls Subjected To Wind Loads, Joshua John Blom

Theses and Dissertations

Although elastic design of the main wind force resisting system in a building is the conventional approach it is not always desirable. In this study, nonlinear static and dynamic analyses are used to predict the inelastic behavior of a three-story building with concrete-filled composite plate shear walls subjected to wind loads. To explore the potential for inelastic design, two types of planar composite shear wall buildings are examined: individual shear walls designed using an elastic approach, and coupled shear wall pairs designed using an inelastic approach adopted from seismic design provisions. Nonlinear static "pushover" analyses are run using an assumed …

Experimental Testing Of Axially Loaded Fuse Plates Without Continuous Buckling Restraint, Rebekah Elizabeth Higgins

Theses and Dissertations

Current seismic design practice is to design structures to avoid collapse and protect life. Buildings are designed to resist seismic loading through strength and ductility. In moment frames, this ductility traditionally comes from inelastic deformation of beams. Moment frame connections move inelastic deformation away from the column and allow a plastic hinge to form in the beam. This plastic hinge prevents collapse but leaves the building difficult to repair. Some proprietary moment frame connections address this issue with replaceable fuse plate connections. These fuse plate connections move the plastic hinge out of the beam and into the replaceable fuse, allowing …

This study aims to elucidate these principles based on the assumption they may be of philosophical and practical value within BYU, as well as higher education more generally. In order to identify the salient teaching and learning principles found within Foundations, I conducted a qualitative textual …

Curious Contradictions: A Critical Edition Of 'The Great War In England In 1897,' By William Le Queux, Jacob D. Liljenquist

Student Works

Written by William Le Queux in 1894, The Great War in England in 1897 is a work of invasion literature, and a book full of curious contradictions. Once popular and now forgotten, its material construction belies its status as sensational literature. This critical edition of the 4th edition copy of the novel housed in the L. Tom Perry Special Collections evaluates the book's conception, creation, and reception, and provides a material bibliography of the HBLL's unique copy, all with the aim to reveal and explain the contradictions in the book as a product of imperial culture.

Travels In West Africa: A Critical Edition, Erere Iwhi

Student Works

First published in 1897, Mary Henrietta Kingsley’s Travels in West Africa became one of the most influential travel narratives of the Victorian era, changing the way British audiences encountered accounts of West Africa and its peoples. This critical edition examines the book not only as a travel narrative but also as a material artifact shaped by the historical, publishing, and cultural networks that guided its production, circulation, and reception. Extending its analysis beyond Kingsley's experiences of exploration, this edition investigates the forces behind the book’s creation, including Kingsley’s intellectual development, her identity as an independent female traveler and writer, and …

The Policy Project: Translating Menstrual Equity Resources, Ashley Jackman

Undergraduate Honors Theses

This creative project focuses on translating key materials from The Period Project, a campaign by the Utah nonprofit The Policy Project that tackles menstrual inequity by pushing for free period products in schools and public spaces. Their educational toolkits guide students and parents toward menstrual resources and outline compliance requirements for school administrators. However, a significant portion of Utah’s population speaks Spanish at home, and current toolkits are not readily available in Spanish. As a Spanish translation major, I saw this as an opportunity to use my skills in a real-world setting, as the translated toolkit will be immediately electronically …

Theses and Dissertations

A multiple baseline single case study design was used to examine the effects of a narrative and resiliency-based intervention for couples with adverse childhood experiences (ACEs). Using piecewise multilevel modeling (MLM), the study evaluated changes in depressive symptoms, dyadic coping (DCI), and growth and empowerment measure (Emotional Empowerment Scale [EES-14] and 12 Scenarios [12S]) across waitlist and treatment phases. Five couples (10 individuals) participated in up to 17 waves, with staggered baseline and treatment lengths across dyads. Results indicated significant fixed effects of the 12S subscale for growth and empowerment during the treatment phase. There were no statistically significant fixed …

Making Space For Learning: Textile Based Learning Resources For Material Reuse, Mary-Evelyn Mcconkie Howell

Instructional Psychology and Technology Graduate Student Projects

This paper outlines two textile-based learning resources that I created for Making Space Thrift (MST), a community-focused creative thrift store in Utah. MST expressed a need for instructional materials that promote intentional material use, support customer well-being, and strengthen ties with their community. To address these needs, I conducted interviews with stakeholders and local textile hobbyists to understand what learning resources would benefit MST. As a result, I created two projects. The first is called Making Peace with Materials, an interactive, decision-based digital experience housed on the MST website. This resource helps learners navigate the emotional, practical, and sustainable …

Power Resilience In Utah's Water Sector: A Survey Of Stakeholder Practices, Preferences And Potential, Tyler Christopher Peterson

Theses and Dissertations

Drinking water and wastewater services are vulnerable to disruptions because they rely heavily on the electric grid. As a result, power outages can lead to water outages, creating cascading failures that compromise sanitation, firefighting, healthcare, and daily routines. Although an important topic, there are little to no studies of water and wastewater power resilience at a geographic or state level. In this study we investigate the extent of existing backup power and renewable energy integration as well as the motivations and barriers around their power resilience. We collect our data through semi-structured interviews with staff at 19 urban and rural …

The Impact Of Social Factors On Vagally Mediated Parasympathetic Activity, Andrew Scot Proctor

Theses and Dissertations

Loneliness and social disconnection are recognized risk factors for morbidity and mortality, yet the psychophysiological pathways remain contested. This dissertation examines how social factors relate to vagally mediated parasympathetic activity indexed by heart rate variability (HRV) and tests whether conversational interventions with a human or a large-language-model (LLM)-based companion can acutely reduce loneliness and enhance connection. Across two university sites (BYU, UCSD), N=297 participants (18-27 years) were randomized to (a) a reciprocal self-disclosure conversation with a trained human confederate, (b) a parallel, vocalized LLM chatbot conversation, or (c) a non-social, vocal reading control. Resting HRV (RMSSD, SDNN, HF-HRV) was recorded …

Experimental And Theoretical Characterization Of Molten Salt Thermal Conductivity, Jacob C. Numbers

Theses and Dissertations

Molten salts form an ideal heat transfer fluid for advanced energy generation systems, including molten salt reactors (MSR). Accurate characterization of molten salt thermal conductivity is needed to confidently predict transient thermal behavior and optimize salt properties. Measurements are hindered by salts' challenging material properties, which---in the case of the needle probe device---induced unaccounted physical changes that limited its accuracy and repeatability. Sparse thermal conductivity data in general is exacerbated by a limited fundamental understanding of molecular energy transfer in liquids. This work extends the experimental capacity for compositional studies using the needle probe and proposes a theoretical model for …

Actionable Insights From The Liahona 1, Yoshihiko Ariizumi

Meaningful Work, Lincoln N. Bay

Undergraduate Honors Theses

I study the relationship that preferences for meaningful work—work that provides utility through more than just income—have with wages and time spent working in a variety of scenarios by developing, calibrating, and validating a Roy-inspired structural model of occupational choice where heterogeneous households choose to provide standard and "meaningful" work, where each type of labor has a distinct wage. Within the framework of the model, I find that meaningful work is associated with lower wages and higher hours; that in response to exogenous transfers, households will work less overall but spend more time on meaningful work; that policies that mandate …

Exploring The Potential Of Artificial Intelligence To Improve The Journal Peer Review Process, Eliza Fanny Bondah

Theses and Dissertations

Academic publishing depends on the peer review process to guarantee quality, scholarly rigor, and credibility, but the traditional peer review system receives mounting criticism because of its inefficient operations, biased judgments, and irregular standards. This study explores how artificial intelligence (AI) can improve journal peer review systems to solve a variety of issues, including reducing reviewer exhaustion, minimizing bias, improving consistency, and accelerating the review process. Current literature shows AI as a promising yet controversial solution, which may provide structured feedback with improved consistency and efficiency. Our study examined 52 human reviews together with 26 AI-generated reviews from EdTechnica--An Open …

Bayesian Alignment Prior To Connectionist Temporal Classification Loss, Lawry Sorenson

Theses and Dissertations

We propose revisions of Connectionist Temporal Classification (CTC) loss and forced alignment to support longer input sequences. CTC loss is normally used for training in speech and handwriting recognition tasks when the labels are not fully aligned with the data, while forced alignment is a downstream task that finds the optimal path for segmentation purposes. The current implementations consider all possible alignments between the input and label, which grows exponentially with the size of the input. We show that in cases when silence is removed and speaking rate is consistent, the true alignment is a mostly straight line across time …

Cracking The Shell: A Corpus-Based Analysis Of The Functions Of Shell Nouns In American Legal Contracts, Geoffrey T. Julian

Undergraduate Honors Theses

The forms and functions of shell nouns (SN), semantically abstract nouns that can package and characterize complex segments of discourse, have been documented in academic discourse and L2 English writing (e.g., Aktas & Cortes, 2008; Benitez-Castro & Thompson, 2015). The abstract nature of SNs lends itself to use where vague language might be favored to allow for a variety of contingencies (Benitez-Castro, 2015). Thus, SNs have also been found to be present in legal language where some of these functions are desirable (Ren et al., 2019). The present study examines the use of SNs in a corpus of 2,700 US …

In Their Own Voice: A Grounded Theory On Overcoming Internet Gaming Disorder, Jayson Carmona

Theses and Dissertations

Internet Gaming Disorder (IGD) is highly comorbid with depression, anxiety, sleep loss, lower productivity, and social isolation. The DSM-5 TR designates IGD as a condition for further study, however the ICD-11 has designed Gaming Disorder as a codified illness. While most studies look at IGD via a medical model lens focusing almost exclusively on symptomology, very little research explores the process of recovery in IGD. In this grounded theory inquiry, a theory of recovery from IGD is generated. Secondary internet data consisted of 113 posts on the subreddit /r/StopGaming on reddit.com. This resulted in 196 pages of data. Researcher used …
