A Masked-Perturbation Model For Destabilization Security Games In Feedback Systems, Gabriel Michael Perry Apr 2026

A Masked-Perturbation Model For Destabilization Security Games In Feedback Systems, Gabriel Michael Perry

Theses and Dissertations

In this thesis, we present a mathematical formulation for increasing cyberphysical system security. This model allows a system administrator to use assumptions about exposed signals to derive defense strategies meant to mitigate the system's vulnerability to feedback perturbation attacks. We begin with a survey of game theory with the goal of building the concepts of resource and security games. We then introduce our model, which is a security game; targets in this game are exposed signals in the model map of the system, and resources are perturbed or introduced dynamical relationships between these signals. This formulation, called the masked-perturbation model, …

Theoretical Expressivity Of Self-Attention As A Model Of Binary Sequence-To-Sequence Functions And Other Explorations, Dustin Angerhofer Apr 2026

Theoretical Expressivity Of Self-Attention As A Model Of Binary Sequence-To-Sequence Functions And Other Explorations, Dustin Angerhofer

Theses and Dissertations

The self-attention mechanism lies at the heart of modern sequential modeling with deep neural networks, especially in the context of Large Language Models (LLMs). The basic role of self-attention is to capture pairwise interactions between tokens in a sequence. This allows token embeddings to be endowed with context-dependent information before further processing. Despite its widespread use, our theoretical understanding of self-attention is still nascent. In this work, we examine self-attention as a model of binary sequence-to-sequence (seq2seq) functions, which is the simplest non-trivial case to analyze. We find, using VC dimension and the Sauer-Shelah lemma, that in the limit of …

Principal Coaching Impact: Elementary Principals' Perspectives On Their Coaching Experience, Kyle L. Hoopes Apr 2026

Principal Coaching Impact: Elementary Principals' Perspectives On Their Coaching Experience, Kyle L. Hoopes

Theses and Dissertations

School principals face increasing complexity as they navigate instructional leadership, organizational change, and the emotional demands of supporting staff and students. Traditional professional development--often episodic and compliance-driven--has proven insufficient for helping principals translate knowledge into practice. This qualitative phenomenological study examined how 20 elementary principals in a large intermountain district experienced a dual-coach, team-based leadership coaching model and how coaching influenced their leadership practices and well-being. Semi-structured interviews and iterative thematic analysis revealed that coaching shaped three core areas of leadership practice: gaining clarity and direction, prioritizing instructional and organizational goals, and strengthening collaboration within school leadership teams. Principals also …

Self-Concept Clarity And Relationship Satisfaction: The Mediating Role Of Approach And Avoidance Motives For Sacrifice Among Heterosexual Couples, Hannah F. Hatch Apr 2026

Self-Concept Clarity And Relationship Satisfaction: The Mediating Role Of Approach And Avoidance Motives For Sacrifice Among Heterosexual Couples, Hannah F. Hatch

Theses and Dissertations

While individuals often engage in relational sacrifice to promote positive outcomes like connection (approach motives), they may also sacrifice for a partner to avoid negative outcomes like conflict (avoidance motives). These distinct motives for sacrifice have been repeatedly linked with divergent couple outcomes, yet little is known about the personal and relational factors which shape them. The current study addressed this gap using dyadic data from 289 mixed-gender couples to examine how self-concept clarity (SCC) predicted changes in relationship satisfaction via approach and avoidance motives for sacrifice. Participants represented diverse ethnic and sociodemographic backgrounds across all demographic regions of the …

The Lookahead Transformer, Justin P. Olcott Apr 2026

The Lookahead Transformer, Justin P. Olcott

Theses and Dissertations

Large Language Models (LLMs) are transformer models that generate text autoregressively in two stages: prefill and decode. The prefill stage processes all input tokens in parallel and caches them into the KV cache. The decode stage uses the KV cache, processes a single token at a time, and is generally memory-bandwidth constrained. Each decode step generates a token probability distribution, samples from it, appends the token to the cache, and repeats. This left-to-right, one-at-a-time generation paradigm has proven effective for language modeling in many domains; however, it also has limitations such as token permanence, constant compute per token generation, constant …

Improving Reclamation Seeding Success Through Seed Technologies, Surface Preparation, And Microbial Inoculants, Josh M. De Santiago Lazalde Apr 2026

Improving Reclamation Seeding Success Through Seed Technologies, Surface Preparation, And Microbial Inoculants, Josh M. De Santiago Lazalde

Theses and Dissertations

Revegetation of reclaimed lands is often limited by poor seed placement, unfavorable surface conditions, and reduced biological activity, particularly on steep or physically degraded substrates where broadcast seeding is commonly used. Improving early seeding establishment under these conditions requires approaches that address both physical and biological barriers to seedling development. We evaluated the effectiveness of surface preparation, seed technologies, and microbial inoculants for improving plant establishment in field and greenhouse settings relevant to mineland reclamation. At the field scale (Chapter 1), we investigated the effects of chain harrowing and seed enhancement treatments on the establishment of grasses, forbs, and shrubs …

Detection Of The Presence And Growth Of E. Coli Bacteria In A Droplet-Based Microfluidic System Using Laser Induced Fluorescence, Oshira Peiris Apr 2026

Detection Of The Presence And Growth Of E. Coli Bacteria In A Droplet-Based Microfluidic System Using Laser Induced Fluorescence, Oshira Peiris

Theses and Dissertations

Antimicrobial resistance is a biomedical event, wherein an infectious microbe becomes non-responsive to the dosage of a particular antibiotic due to previous overuse or overexposure. Currently, agar plate disc diffusion is used as the gold standard for detecting antimicrobial resistance. The possibility of miniaturizing and speeding up detection techniques for antimicrobial resistance is investigated in this thesis. Microfabrication techniques were used in developing two droplet microfluidic systems interfaced with laser induced fluorescence detection. Microfluidic devices were manufactured with different droplet generating geometries using poly-dimethyl siloxane, soft lithography and hydrophobic surface treatment. The microfluidic devices were tested for droplet quality using …

Answers “Go By Water”: Felt Knowledge As An Alternative Epistemology In Othello, Annalisa Gulbrandsen Apr 2026

Answers “Go By Water”: Felt Knowledge As An Alternative Epistemology In Othello, Annalisa Gulbrandsen

Theses and Dissertations

William Shakespeare's Othello is fundamentally a play about epistemology--how does one know what he/she knows amidst the sea of words, evidence, and misdirection? Traditionally, the problem of knowledge in Othello has been treated as an intellectual problem of the mind. However, this thesis argues that the play purposefully draws attention to the limits of what the mind can know by way of the eye (what is seen) and ear (what is spoken or heard), instead offering an alternative epistemology that is felt through embodiment. When Desdemona's words no longer have the power to affect what Othello believes, Desdemona's answers to …

Model Unification: A Systematic Approach For The Cluster Expansion, Kolten Barfuss Apr 2026

Model Unification: A Systematic Approach For The Cluster Expansion, Kolten Barfuss

Theses and Dissertations

A systematic approach for model unification of cluster expansion models is developed and demonstrated. The method builds on previous work with the Manifold Boundary Approximation Method (MBAM) to identify supremal models. The work is motivated by the exercise of unifying cluster expansion models – characterized by Π matrices – for two binary alloys that share one atomic species to form a model for the ternary alloy. The result is the Supremal Π Algorithm, a systematic unification algorithm that relies on an MBAM-informed understanding of models and on the singular value decomposition. The algorithm yields ΠΛ, a Π matrix for the …

The Artificial Maintenance Of Relationship Satisfaction: Romantic Ai Companion Usage Sustains Emerging Adults' Human Romantic Relationship Satisfaction While Eroding Relationship Stability, Rebekah M. Hakala

Theses and Dissertations

As artificial intelligence becomes increasingly sophisticated, romantic AI companions--AI systems designed to simulate romantic, emotional, or sexual relationships--have emerged as a novel relational phenomenon. Nearly one in four emerging adults now engage with romantic AI companions, yet little is known about how this usage affects their romantic human relationships. Drawing on Social Exchange Theory and the Investment Model of Commitment, and employing structural equation modeling, this thesis uses data from 2,431 emerging adults in romantic relationships to examine whether romantic AI companion usage influences relationship satisfaction and relationship stability among emerging adults in the United States (ages 18-30), and whether …

Impacts Of Arbuscular Mycorrhizal Fungi And Novel Soil Amendments On Perennial Grass Establishment In Mineland Soils, Melissa M. Burrell Apr 2026

Impacts Of Arbuscular Mycorrhizal Fungi And Novel Soil Amendments On Perennial Grass Establishment In Mineland Soils, Melissa M. Burrell

Theses and Dissertations

Establishing perennial vegetation on mine waste materials is one of the primary challenges in mine land reclamation. Waste rock and mine tailing substrates typically lack the physical structure, nutrient availability, and biological communities necessary to support plant establishment and long-term ecosystem recovery. As a result, revegetation efforts often experience poor seeding success and limited plant persistence despite intensive management efforts. These studies investigated two complementary strategies to improve perennial grass establishment in degraded mine substrates: restoring mycorrhizal associations and enhancing soil function through soil amendments. The first study examined the role of arbuscular mycorrhizal fungi (AMF) in facilitating plant establishment …

Some Closure On The Relation Between Cfg And Peg, Nathan J. Bulloch Apr 2026

Some Closure On The Relation Between Cfg And Peg, Nathan J. Bulloch

Theses and Dissertations

We work toward a practical, unified language formalism for structurally recursive languages by expressing the mathematical theories underlying context-free grammars with lookahead (CFGLA) in the Rocq theorem prover and leveraging CFGLA semantics to analyze interactions between between recursion and negative lookahead. We give examples of grammars with left-recursive negation cycles for the parsing expression grammar (PEG) variant due to Medeiros et al. and for the translation from PEG to CFGLA due to Miyazaki and Minamide. To study the interaction between left recursion and negative lookahead in a PEG context, we introduce FPEG, a left-recursive extension of PEG with Fitting semantics.

Composing In Relation: Rethinking Multimodal Feedback As Rhetorical Design, Angela Laflen Apr 2026

Composing In Relation: Rethinking Multimodal Feedback As Rhetorical Design, Angela Laflen

Journal of Response to Writing

This qualitative study investigates how writing instructors compose feedback in multimodal digital environments, focusing on the rhetorical and relational dimensions of their design choices. Drawing on social semiotics and multimodal composition theory, the study analyzes feedback artifacts, instructor interviews, and student surveys from six first-year writing courses. Findings reveal that instructors engage in complex feedback design work across communication modes, often without formal training or shared frameworks. Instructors tended to default to text-based habits shaped by genre memory but adapted their strategies in response to communicative breakdowns and student needs. The study identifies three core themes: reliance on print-era conventions, …

Integrating Traditional Samoan Music With School-Aged Children In Fostering Culturally Appropriate Behaviors Within The Framework Of Fa'afaletui And Multimodal Interpretative Phenomenological Analysis, Stormi Rachelle Winscot Apr 2026

Integrating Traditional Samoan Music With School-Aged Children In Fostering Culturally Appropriate Behaviors Within The Framework Of Fa'afaletui And Multimodal Interpretative Phenomenological Analysis, Stormi Rachelle Winscot

Theses and Dissertations

Fa’aSamoa, the cultural framework shaping Samoan values, relationships, and daily life, deeply informs educational experiences in American Samoa. Music, as both cultural expression and communal practice, offers a powerful lens through which student engagement can be understood. This exploratory study employed multimodal interpretative phenomenological analysis (MMIPA), guided by the Fa’afaletui framework, to examine how Samoan and Pacific Islander students responded in embodied ways to traditional Samoan, culturally adapted Western, and other Western (folk, classical, pop) music in classroom settings. Drawing on focus group interviews and systematic observations, the study centered students’ movement, vocal expression, rhythmic participation, and peer interaction as …

Shame On You! The Socialization Of Self-Conscious Emotions In Early Childhood, Ashton K. Allen Apr 2026

Shame On You! The Socialization Of Self-Conscious Emotions In Early Childhood, Ashton K. Allen

Theses and Dissertations

This study examined how parents and children discuss self-conscious emotions across early childhood. Self-conscious emotions such as shame, guilt, embarrassment, awe, and pride play a critical role in children's social and emotional development. Although prior research has demonstrated links between parent and child emotion talk about basic emotions such as happiness, anger, disgust, fear, sadness, less is known about how parents and children talk about self-conscious emotions. Participants for the current study were 247 parent-child dyads. The dyads completed a wordless storybook task designed to elicit discussion of five self-conscious emotions (shame, guilt, embarrassment, awe, and pride) annually across three …

Biomass Fuel Processing, Mineral Matter Engineering, And Ash Phase Equilibria For Deposition Control In Coal To Biomass Boiler Conversion, Spencer Bandi Apr 2026

Biomass Fuel Processing, Mineral Matter Engineering, And Ash Phase Equilibria For Deposition Control In Coal To Biomass Boiler Conversion, Spencer Bandi

Theses and Dissertations

As the conversion of coal utility boilers to 100% biomass combustors gains traction, understanding the interconnected impacts of harvesting and storage methods, fuel preparation, and thermochemical ash behavior is critical. This study evaluates miscanthus, switchgrass, and corn stover, targeting a < 1000 µm particle size through minimal (shredders/hammer mills) and heavy (pelletizing) pre-treatment. While heavy pre-treatment failed in a coal mill, minimal pre-treatment succeeded. Miscanthus (forage-harvested/silage-bagged) proved optimal, exhibiting minimal exogenous mineral accumulation up to (1.26 w%) and the smoothest mechanical feeding (deviation < 9%) due to its low particle aspect ratio. Conversely, baled switchgrass and corn stover accumulated up to 9.23 w% mineral matter and exhibited severe feeding resistance (>17% deviation) driven by fibrous, high-aspect-ratio morphologies. During combustion, agricultural residues yield low ash fusion temperatures (AFTs), generating deposits two to three times stronger than coal. To mitigate this severe fouling, mineral additives (coal fly ash, lime, and cement kiln dust) were injected. These additives effectively raised bulk AFTs and reduced deposit tenacity by up to 73%. Specifically, 2 w% …

Utah Secondary English Language Arts Teachers And The Use Of Body Diverse Young Adult Literature, Katy Johnson Bigham Apr 2026

Utah Secondary English Language Arts Teachers And The Use Of Body Diverse Young Adult Literature, Katy Johnson Bigham

Theses and Dissertations

Representation in young adult (YA) literature has expanded significantly in recent years, but body size diversity - specifically the inclusion of fat protagonists - is still minimal and understudied in secondary English language arts (ELA) classrooms. Research shows that diverse literature plays a crucial role in helping students see themselves and other reflected in the texts they read, as shown in the metaphor of literature as "windows, mirrors, and sliding glass doors" (Bishop, 1990). So how does this apply to the representation of body size diversity in the ELA classroom? This study explores how secondary ELA teachers in Utah perceive …

Psoas Muscle Volume Asymmetry, Not Attachment Site Asymmetry, Is Associated With Chronic Low Back Pain Status, Kassity D. Clay Apr 2026

Psoas Muscle Volume Asymmetry, Not Attachment Site Asymmetry, Is Associated With Chronic Low Back Pain Status, Kassity D. Clay

Theses and Dissertations

Chronic low back pain (CLBP) is a leading cause of disability worldwide, with increasing evidence implicating neuromuscular factors such as muscle asymmetry in its pathophysiology. The psoas major muscle (PMM), a key contributor to lumbar spine stability, has been comparatively under-investigated despite its biomechanical importance. PURPOSE: To determine whether right-to-left differences in PMM volume and attachment site asymmetry are associated with CLBP; to evaluate whether ODI, IPAQ, and age are associated with PMM volume imbalance; and to assess whether combined PMM volume and attachment asymmetry are associated with CLBP. METHODS: A retrospective secondary analysis was conducted using lumbar MRI data …

"A Politics Of Its Own": Reading Adelaide Procter's Poetry In The Context Of The English Woman's Journal, Rachel Diane Gouff Apr 2026

"A Politics Of Its Own": Reading Adelaide Procter's Poetry In The Context Of The English Woman's Journal, Rachel Diane Gouff

Theses and Dissertations

Victorian poet Adelaide Anne Procter, a devout Catholic and a nineteenth-century feminist and social activist, was hugely popular in her lifetime for her devotional and sentimental poetry. However, scholars who have looked closely at her work have recognized that her poetry contains moments of tension that suggest they may be more than they appear on the surface. Such tensions and ironies are often glossed over or misread by readers whose expectations of Christian devotional messaging and domestic sentiment overshadow the contradictions. In this paper, I propose that one of the most effective ways to more fully understand the nuance and …

Affective Archives: Friendship And Material Intimacy In The Manuscripts Of Dora Wordsworth And Maria Jane Jewsbury, Madison Elizabeth Maloney Apr 2026

Affective Archives: Friendship And Material Intimacy In The Manuscripts Of Dora Wordsworth And Maria Jane Jewsbury, Madison Elizabeth Maloney

Theses and Dissertations

Manuscripts have long been analyzed for how they circulated alongside traditionally published texts, with scholars taking an interest in both the content and material form of such documents. In a print-centric era like the early nineteenth century, the surplus of published writing was sometimes framed as impersonal and generic. As such, material elements of manuscripts like paper, ink, and handwriting were increasingly valued as affective reflections of authors' bodies and circumstances. For example, tear stains on a letter might allow for a more personal and meaningful connection between writer and reader than the homogeneity of mass-produced texts. In a project …

"But Will I Get In Trouble?": Negotiating Teacher Identity And Self-Censorship Amid Book Bans In Utah, Annika Nielson Apr 2026

"But Will I Get In Trouble?": Negotiating Teacher Identity And Self-Censorship Amid Book Bans In Utah, Annika Nielson

Theses and Dissertations

Book banning is becoming an increasingly prominent and contested issue in the United States. The focus usually lies on school and district policy, banned book lists, and state legislation, but the impact on the daily lives of teachers is often overlooked. Their decision-making processes are key to determining the books that make it into classrooms, and self-censorship often occurs prior to formal book bans (Watkins & Ostenson, 2015; Woo et al., 2023). This study examines how teachers experience book banning in their individual lives through the way they navigate competing pressures and values when selecting books to teach. Utah teachers …

Metonymy In Sound: A Neurolinguistic Study Of Al-Mullalah Soundscape Using Fnirs, Rand Naser Muflih Apr 2026

Metonymy In Sound: A Neurolinguistic Study Of Al-Mullalah Soundscape Using Fnirs, Rand Naser Muflih

Theses and Dissertations

This thesis offers an interdisciplinary exploration of the semantic and neurolinguistic development of Al-Mullalah, a traditional Palestinian "coded" song type. By combining metonymy, soundscape analysis, and functional neuroimaging, the study traces the evolution of Al-Mullalah from a localized, covert means of communication tied to historical struggle to a globally recognized auditory symbol of collective resilience. The research uses a multi-method approach. First, soundscape analysis demonstrates how Al-Mullalah functions within Palestinian aural counterpublics, strengthening communal memory through various uses. Second, a qualitative analysis of semantics and themes examines how the text's metonymic structures change over time. Lastly, a Functional Near-Infrared Spectroscopy …

Silicon Dioxide Multimode Interferometer Spectrometers, James Harkness Apr 2026

Silicon Dioxide Multimode Interferometer Spectrometers, James Harkness

Theses and Dissertations

Multi-mode interferometer (MMI) spectrometers are a type of reconstructive micro-spectrometer based on imaging light propagation patterns in MMI waveguides. This dissertation describes how the MMI spectrometer was implemented for the first time using a silicon dioxide core. This approach showed a 6 dB improvement in SNR over SU-8 core devices. To implement the silicon dioxide MMI spectrometer, a fabrication technique for selectively roughening the surface of the waveguide needed to be developed. SU-8, a photosensitive polymer, was etched with oxygen plasma to create grass-like nanostructures. SU-8 grass can then be used as a transfer mask to plasma etch a surface. …

Subversive Speculative Theology In Women's Stories From The Mormon Home Literature Movement, Rachel Meibos Helps Apr 2026

Subversive Speculative Theology In Women's Stories From The Mormon Home Literature Movement, Rachel Meibos Helps

Theses and Dissertations

In the 1910s, Mormon women used sentimental speculative fiction published in official Relief Society Magazine to engage theological questions often reserved for male ecclesiastical authority. This paper examines three short stories: Edna Coray's "A Quitter–Almost." (1918), Lucy May Green's "A Whiff of Ether" (1919), and Laura Jenkins's "Beyond the Portals" (1916), each of which depicts a woman's encounter with the spirit world at the moment of death or near-death. Drawing on the Mormon Home Literature movement and the broader tradition of sentimental fiction as political and moral discourse, I argue that these authors used narrative to fill gaps in official …

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely Apr 2026

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely

Theses and Dissertations

Polymer-coated urea (PCU) is widely used as a slow-release nitrogen (N) fertilizer because it improves N use efficiency and reduces losses through leaching, denitrification, and volatilization. However, the polymer coating raises concerns about potential microplastic (MP) transport to surface waters following fertilizer application. This thesis evaluates the off-site transport of MPs and associated nutrient and sediment losses from PCU in both urban landscape and agricultural systems. In the urban landscape study, treatments included sod, mulched beds, and water-efficient ground cover receiving uncoated urea, PCU, or liquid slow-release N at 225 kg N ha⁻¹ (with reduced rates for beds and ground …
