Galois Action And Arithmetic In Algebraic Number Fields, Jared Kettinger

All Dissertations

This dissertation explores the arithmetic of numerous algebraic objects living within an algebraic number field from submonoids of the integers up to localizations of the ring of integers. We begin with a study of factorization in proper orders using an element-theoretic approach. In Chapter 2, by defining a natural generalization of the Davenport constant, we are able to determine the elasticity of certain orders whose integral closure is a unique factorization domain. In Chapter 3, using ideal-theoretic analogues, we are able to significantly broaden the scope of our results and the literature on factorization in orders. In particular, we give …

Integrating Incentive Design And Spatial Prioritization For Climate-Smart Forestry Adoption In South Carolina, United States, Miah Maye Pormon

All Dissertations

Forests provide essential ecosystem services, including carbon sequestration, water regulation, timber production, and habitat provision. However, increasing development pressures and land-use changes threaten forest persistence and long-run ecosystem service provision. Climate-smart forestry (CSF) practices, such as improved forest management and extended rotation, offer opportunities to enhance carbon storage, forest resilience, and economic livelihoods. The effectiveness of these practices depends on forest owners’ participation and the strategic allocation of financial resources or incentives. This dissertation develops an integrated framework that combines behavioral economic analysis and mapping to improve the design of current incentive programs. The first chapter employs the Contingent Valuation …

Development Of A Mixing-Controlled Combustion Model For 0d Engine Modeling: Using High-Order Models To Guide The Formulation Of Reduced-Order Models, James Gohn

All Dissertations

Vehicles are becoming increasingly complex to comply with the increasingly stringent regulations placed on all market sectors while still maintaining performance requirements. This increased complexity leads to increases in the cost and time it takes to develop and produce these next generation vehicles. To meet demand therefore, it becomes necessary to evaluate numerous design iterations using computer models. There are multiple levels of models that may be necessary for different purposes or use cases. All levels of modeling for virtual prototyping, however, require a level of validation and predictive ability to be useful. To this end, the following thesis presents …

X-Raying The Material Surrounding Active Supermassive Black Holes, Isaiah S. Cox

All Dissertations

It is important to understand the nature of the gas and dust immediately surrounding the supermassive black hole (SMBH) in active galactic nuclei (AGN), because this material feeds the accretion disk and couples the activities going on at the AGN scale to the host galaxy. However, there remain large uncertainties on basic properties about this material such as its location and distribution. This is primarily due to the difficulties in resolving spatial information on these scales at extragalactic distances.

AGN emit a tremendous amount of radiation all across the electromagnetic spectrum, including X-rays. The X-rays come from a very small …

Geography, Income, And The Incidence Of A Massachusetts Carbon Tax, Susan Stratton Sayre

Economics: Faculty Publications

I use spatial microsimulation to estimate the geographic incidence of the consumer-facing portion of various revenue-neutral carbon tax designs in Massachusetts. I identify a substantial urban-rural disparity in impacts that is reduced, but not eliminated, by proposed revenue-targeting mechanisms. I further demonstrate that seemingly small variations in the definition of rural households can have substantial impacts on urban-rural equity and the distribution of gains and losses. Proposed policies are highly progressive in the aggregate with most low-income households receiving more in rebates than they pay in taxes, but notable numbers of low-income households are likely to experience significant losses. Methodologically, …

A Climatology Of Sudden Stratospheric Warmings And Their Tropospheric Response, Joe Lovelien, Mark Sinclair

Publications

Sudden Stratospheric Warmings (SSWs) are major disruptions of the wintertime polar vortex that can significantly influence surface weather, including cold air outbreaks (CAOs) across the midlatitudes. This study presents a climatology of SSWs from 1948-2024 using NCEP-NCAR reanalysis data and examines their temporal distribution, relationships with large-scale climate variability, and impacts on surface temperatures in the United States. SSWs are identified using previously published definitions based on the reversal of zonal-mean winds at 60°N and 10 hPa. A total of 44 SSW events were identified, with a strong seasonal preference for January through March. Some decadal variability is observed, though …

An Expertise-Based Approach To Training Decision-Making And Situational Awareness For Basketball Referees, Scott Warner Boatright

Dissertations

Expertise, rapid decision-making, and situational awareness are key components of high performance in many areas, including basketball officiating. Traditional methods of providing feedback on performance to basketball referees rely heavily on broadcast video and rule review, which does not adequately target the perceptual-cognitive skills associated with rapid and dynamic decision-making. The current study developed and evaluated a 360-degree video virtual reality (VR) Expertise-Based Training (XBT) program designed to accelerate expertise in intermediate-level basketball referees. Using think-aloud protocol, conducted with an expert basketball referee, expert judgments and rational were elicited and implemented as Expert-Model Feedback within the referee training program. Twelve …

Analysis Of Oscillating Flow Over A 2-D Airfoil With Flow Reversal, Colter Couillard-Rodak

McKelvey School of Engineering Graduate Student Theses & Dissertations

Finite-state models are useful tools in modeling the aerodynamics of rotorcraft in flight simulators. 2-D and 3-D finite-state models have been developed and compared to closed form solutions, however these models are currently unable to handle situations where the freestream changes directions and the rotor re-enters its own wake. A 2-D finite state model was previously developed that includes a parameter that accounts for the change in free stream. This model, however, contains an inherent stability issue at the instant that the velocity changes direction.

The effects of this instability can be mitigated in certain flow conditions. A purely oscillatory …

Multiscale Architecture Governs Stability In Suction-Actuated Variable Stiffness Catheters, Sheridan Lee

McKelvey School of Engineering Graduate Student Theses & Dissertations

Endovascular procedures require devices with widely varying mechanical properties: flexibility for navigating tortuous vessels and rigidity for stable therapeutic delivery. Suction-actuated variable stiffness sheaths address this challenge by incorporating axial wire string arrays that mechanically couple under suction to increase flexural rigidity. However, prototype devices achieve stiffening ratios below theoretical predictions, suggesting that interlayer mechanics and string positioning play a critical role. This study investigates whether interweaving polytetrafluoroethylene (PTFE) tape within the string array enhances flexural rigidity modulation and curvature stability. Prototype devices with varying wrap configurations were fabricated and evaluated using flexural testing, curvature stability testing, and mathematical modeling. …

Computational Fluid Dynamics (Cfd)-Based Performance Prediction Of Transcatheter Microvascular Plugs In Single-Ventricle Patients, Zhuhuan Zou

McKelvey School of Engineering Graduate Student Theses & Dissertations

Transcatheter palliation using fenestrated Modified Micro Vascular Plugs (MVP) has emerged as a promising, minimally invasive alternative to surgical pulmonary artery banding (PAB) for high-risk neonates with single-ventricle physiology. However, clinical applications are currently limited by the difficulty in predicting the resulting pulmonary-to-systemic flow ratio () and the lack of a standardized approach for selecting the optimal fenestration size. This study utilizes patient-specific computational fluid dynamics (CFD) to quantitatively evaluate the impact of varying fenestration diameters on circulatory balance. Patient-specific 3D models of the pulmonary artery (PA) were reconstructed from imaging data for two clinical cases using SimVascular. Transient CFD …

Conditioning Hierarchical Diffusion Transformers On Rf Circuit Parameters, Ethan Morton

McKelvey School of Engineering Graduate Student Theses & Dissertations

As modern ML techniques have become increasingly advanced, they have begun to be integrated into wireless RF systems for classification, identification, and spectrum management. Deep Neural Networks (DNNs) enable RF system operators and designers to design more flexible systems with greater robustness to errors and attacks. However, neural networks require significant amounts of properly annotated data to train. Current data labeling methods lack the ability to obtain reliable true labels for circuit properties such as carrier frequency offset (CFO), power amplifier (PA) non-linearity, and in-phase/quadrature (IQ) imbalance. This thesis investigates the efficacy of a novel architecture, RF-Diffusion, for generating high-quality …

Modeling Water Quality And Cyanobacteria Blooms In St. Lucie Estuary, Florida, Mohmmad Masudur Rahman

Electronic Theses and Dissertations 2020 - Present

The St. Lucie Estuary (SLE) on Florida’s east coast is vital for diverse aquatic life and provides essential services to local communities. However, the estuary’s health is threatened by water quality deterioration due to nutrient-driven phytoplankton blooms, particularly cyanobacteria, which have increased in frequency over recent decades. These blooms may worsen water quality by reducing dissolved oxygen, altering pH, and increasing turbidity. Moreover, some phytoplankton species, including Microcystis aeruginosa, a freshwater cyanobacteria species, produce harmful toxins, posing risks to both marine aquatic life and human health in this area. Primary nutrient sources in this estuary include watershed freshwater discharges, …

To characterize the motion of the device under varying sea conditions, wave–structure interactions are analyzed in detail. Performance is evaluated through numerical wave field modeling using WEC-Sim, which enables the simulation of realistic ocean conditions and the estimation of energy that could be extracted at a selected deployment site. In addition to modeling, this study addresses practical engineering challenges associated with the device, with particular emphasis on hardware optimization to mitigate water ingress – …

Influence Of Asd On Morality, Spencer Brown

Harriet L Wilkes Honors College Theses 2020 - Present

Autism is known as a developmental disorder that incurs a social skills deficit on those that have it. This social skills deficit has been proposed to affect further aspects of autistic people’s psychology such as empathy and morality. Studies using the moral stages theory of development have found that those with autism are deficient in these proposed social skills. However, further research into how morality and empathy, as well as the results of experiments looking into morality in autistic populations, have brought the accuracy of moral reasoning into doubt. In the present paper, we review the literature on how empathy, …

Nature And Nurture: The Cognitive Image Of A Building And Its Site, Treyton Hardy

Architecture Theses

Current specialized care facilities often prioritize functionality over the emotional and psychological well-being of their residents. For individuals experiencing dementia, illegible architectural layouts hinder spatial problem-solving and cause severe disorientation. This thesis introduces "Nature & Nurture," a comprehensive dementia recovery and research community proposed for Duluth, Minnesota. By utilizing Kevin Lynch’s Five Elements of the cognitive image, this project establishes an evidence-based architectural framework designed to reduce cognitive load. The design integrates multi-sensory wayfinding cues, continuous circulation paths, and hyper-local landmarks to facilitate environmental recognition rather than demanding complex memory recall. Ultimately, this thesis demonstrates how legible spatial design can …

Monastic Design: Recovering The Sacred, Thomas Larkin Derek Crompton

Architecture Theses

Throughout history, transcendental meaning has been woven into the very fabric of architecture to awaken and attune our souls toward a greater understanding of the inherent, unquantifiable aspects of life. Design elements such as light, material, proportion, and mystery were used as communicators of meaning rather than merely tools of utility. However, with the rise of positivism in the modern period, many transcendental elements of design were disregarded in favor of a more functionalist approach. The strategies employed by this approach influenced much of modern religious architecture and have resulted in many churches that lack the fundamental principle they claim …

Curating Sense-Of-Place In Residential Development: The Development Of A Strategy For Residential Construction, Ryan Anthony Calhoun

Architecture Theses

This thesis addresses the dual-faceted United States housing crisis, characterized by economic inaccessibility and a deteriorating sense-of-place due to urban sprawl and homogenous tract housing. The research investigates how architectural intervention can create a profound sense-of-place within the contemporary residential landscape despite escalating construction costs. By synthesizing phenomenology, housing economics, and urban planning, the study develops a new residential construction stratagem. This strategy utilizes social, economic, and ecological optimizations, such as shared liminal spaces, mass customization, and vernacular design, to foster community and identity. The research culminates in the design of "Prairie Haven,” a 174-lot medium-density neighborhood in Forest Lake, …

The Phenomenology Of Home: Exploring The Interlinked Relationships Between Dwelling And Domestic Architecture, George Martin Grunklee

Architecture Theses

This thesis explores the concept of home from a phenomenological perspective to inform a communication method and design process for domestic architecture. While “home” holds multiple meanings, this study traces the phenomenological relation between human’s embedded existence and place—to understand home as a condition shaped by the lived experiences of its inhabitants. The aim of this thesis is to understand how the design of domestic architecture is intrinsically linked to dwelling and to the accumulation of lived experiences.

The thesis critically engages phenomenology in architectural practice by exploring case studies which exhibit and foster the concept of home. Frank Lloyd …

From Steel To Sanctuary: Rethinking Sustainable Architecture Through Passive Design, Trent O'Neill

Architecture Theses

Architects, innovators, and the entire construction industry continue to push the newest, most expensive, high-tech solutions to problems that technology itself has caused. The broader public, however, seems to have little interest or support in investing in such endeavors. From Steel to Sanctuary presents a different solution, one with roots thousands of years in the making. Sustainable design is not a new way of thinking. Our ancestors had subsisted as active participants, rather than simply as a spectator to nature for millennia before the rise of the technological age. Today, we coin the strategies they employed as ‘passive’ architecture; Systems …

Building On Memory: Towards A Digital Future Informed By Historical Theory, Lucas Laskow

Architecture Theses

This project synthesizes 2,000 years of architectural theory to establish an ethical framework for integrating artificial intelligence into contemporary design. The research culminates in “The Chandler,” demonstrating how AI can enhance, rather than replace, human-driven spatial and cultural values.

The assertion that human design is inherently superior to artificial intelligence relies on the flawed premise that intuitive leaps outweigh data-driven synthesis. Rather than diminishing the architect’s role, the evolution of AI demands that designers become ethical interpreters who ask the right questions. This project investigates how past architectural theorists, from Vitruvius’s foundational triad to Bruce Allsopp’s humanist return, provide a …

Architecture As A Camera: Utilizing Photographic Principles To Tell Stories Through Design, Ryan Gabriel Scherf

Architecture Theses

This thesis examines the relationship between memory, photography, and architecture as a framework for spatial design, framing memory as a fragmented phenomenon contingent upon light and time. Drawing on the theoretical work of Goffi, Barthes, and Bordeleau, it positions architecture as a temporal montage in which meaning emerges through layered absences, material “puncta,” and the interpretive gaps between fragments. Situated at the Botallack Mines in England, the project explores the intersection of photographic logic and industrial ruin by treating the site’s extractive history as a series of active fragments. Through compressed volumes and curated views, it translates photographic principles into …

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, underscoring the need for improved strategies in diagnosis, treatment, and disease modeling. Traditional in vitro models often fall short in replicating human CV physiology, prompting efforts to advance cardiac tissue engineering and computational modeling. Among these, three-dimensional (3D) bioprinting has emerged as a transformative tool, enabling the creation of biomimetic CV constructs that more faithfully replicate native tissue structure and function. However, challenges persist in achieving appropriate mechanical properties and long-term performance of engineered CV constructs. Computational modeling offers powerful solutions to assist with these challenges, providing predictive insights into …

Low Methane Emissions From Nutrient-Rich Former River Channels In A Hydrologically Managed Dryland Delta, Siena Stassi, Jude A. Benavides, Chu-Lin Cheng, Marcelo Gomes Da Silva, Nicholas E. Ray, Nathan O. Barros, Rafael M. Almeida

School of Earth, Environmental, & Marine Sciences Faculty Publications

Anthropogenic stresses in dryland regions can alter hydrology, salinization, and biogeochemical processes. How these pressures influence methane (CH4) cycling and emissions from aquatic ecosystems remains poorly understood. Over the course of 1 year, we measured diffusive and ebullitive CH4 emissions from resacas—shallow, hydrologically managed distributary channels prevalent throughout the Lower Rio Grande Valley along the US–Mexico border. Despite warm, nutrient-rich waters, CH4 emissions from resacas were low, and more comparable to rates observed in estuarine systems. CH4 fluxes were positively related to temperature but negatively related to salinity and rainfall. Elevated salinity, driven by evaporation and source water from the …

2-D Materials: The Synthesis Of Solid-State Fuel From Metastable Diboride, Alma Kolakji

Chemistry

2-D materials are widely recognized for their anisotropic mechanical and electrical properties, surpassing their bulk counterparts. These superior characteristics of 2-D materials arise from their high surface-to-volume ratio and strong in-plane bonds. Current routes to exfoliate bulk material into 2-D nanosheets rely on weak interlayer Van der Waals forces and traditional top-down techniques. These methods are dominated by physical “force,” such as liquid-phase and mechanical exfoliation. The downside is that they apply only to weakly bonded VdW materials, limiting the variety of possible 2-D materials. To expand the variety, researchers have studied the synthesis of borophene (boron sheets). Borophene is …

Leading Ai Adoption In Organizations: Introducing A Behavioral Human-Centered Approach, Shane Schweitzer, Devesh Narayan, Jack Mcguire, David De Cremer

Research Collection Lee Kong Chian School Of Business

Initiatives to implement AI technologies in organizations fail at an alarming rate. We argue that leading the adoption of AI is not a simple engineering exercise but rather represents a behavioral exercise where change management principles—the process by which organizations plan, implement, and embed changes in practices—are employed. However, many AI initiatives in business focus predominantly on the AI systems themselves, assuming humans will fall in line. To solve this, we integrate ideas from change management with scholarship on human-centered artificial intelligence to offer a behavioral approach that accounts for the impact of AI adoption on humans at all stages …
