The Role Of Autonomy, Competence, And Relatedness In The Relationship Between Ai Use, Resilience, And Motivation Among Engineering Students, Daniel Kane

All Graduate Theses and Dissertations, Fall 2023 to Present

The purpose of this study was to determine how the widespread use of Artificial Intelligence (AI) influences engineering students’ motivation and resilience. Specifically, the role of autonomy, competence, and relatedness as defined in Self-Determination Theory (SDT) was assessed to determine how these basic psychological needs interact with students’ AI use and motivation or resilience. The following research questions guided the study: (1) To what extent do the three basic psychological needs defined in SDT (autonomy, competence, and relatedness) mediate the relationship between the frequency of AI use and students’ levels of motivation (on the self-determination continuum) or resilience in an …

Cadmium Biosorption By Fusarium Venenatum And Its Application In Functional Permeable Materials For Metal Removal, Bradley Lawson

All Graduate Theses and Dissertations, Fall 2023 to Present

Heavy metals are pollutants of increasing concern as continued industrialization and urbanization have escalated the discharge of these toxins into aquatic environments.

Given these characteristics Cd poses significant health risks to both humans and aquatic ecosystems. The continued development of sustainable, low-cost remediation technology is imperative to manage metal pollution.

This research explores the use of fungal-based remediation systems to remove Cd from contaminated water. Living biomass of the filamentous fungus Fusarium venenatum was evaluated as a biosorbent material for Cd …

Comparative Analysis Of Strain-To-Velocity Conversion Methods For Active-Source Das Data And Collocated Nodal Stations, Prajwal Panthi, Brady R. Cox

Civil and Environmental Engineering Student Research

Distributed Acoustic Sensing (DAS) provides dense spatial measurements of the dynamic strain along fiber optic cables, offering high-resolution wave sensing for ground motion monitoring and subsurface imaging applications. However, DAS records the axial strain or strain rate, whereas traditional seismic and engineering ground motion equipment and derived metrics are based on particle displacement, velocity, or acceleration, necessitating reliable strain-to-velocity conversion methods. This study evaluates three widely used conversion approaches: the fk-rescaling, curvelet-based conversion, and slant-stack methods. These approaches are applied to a unique high-energy, near-field, active-source dataset collected at the Birds Landing Site in Sherman Island, California. The dataset includes …

Technological Advancements Of Hybrid Rocket Engines For Sustainable And Competitive In-Space Propulsion Applications, Ryan J. Thibaudeau, Stephen A. Whitmore, Jared Coen, Joshua Sorenson, Logan Mecham, Ava Wilkey

Mechanical and Aerospace Engineering Student Publications and Presentations

Hybrid rocket engines (HREs), which pair a fluid oxidizer with a solid fuel, offer safety and handling advantages, can reduce environmental impact relative to selected legacy systems, and are capable of deep throttling and restart, making them strong candidates for “green” in-space propulsion applications. However, until very recently, there has not been any flight heritage of an HRE used in a spaceflight mission. Over the past decade, the Propulsion Research Laboratory at Utah State University (PRL-USU) has matured a portfolio of HRE technologies—low-energy arc ignition, digital throttling, additively manufactured sustainable fuels, the Nytrox green oxidizer, and electroplated thruster assemblies—that together …

Geothermal Energy In Utah: A Safe Technology With Limited Environmental Impacts, Joseph Harding, Kendall Becker, Logan Mitchell, Jennifer Bodine, Scott Hotaling

All Current Publications

Geothermal energy has the potential to transform Utah’s electricity landscape, driving a future with improved air quality, lower carbon emissions, and fewer environmental impacts. In this fact sheet, we provide an overview of geothermal energy and its potential environmental implications in Utah. We highlight that recent geothermal projects in Utah do not use fresh water and that new well designs are expected to reduce the consumption of salty, brackish water. If these efforts are successful, geothermal energy would have lower water consumption, reduced seismic risk, and a similarly low land-use footprint compared to fossil fuel sources of electricity.

Nozzle Erosion Reconstruction Model For Data Analysis In Rocket Engines And Correlation With Chamber Pressure, Ryan J. Thibaudeau, Stephen A. Whitmore

Mechanical and Aerospace Engineering Student Publications and Presentations

Graphite nozzles remain the dominant choice for small hybrid and solid rocket motors operating on laboratory and university budgets, owing to their low cost, ease of machining, and rapid turnaround during iterative design campaigns. These same programs, however, must contend with the fact that graphite erodes through coupled thermochemical and mechanical mechanisms when exposed to the oxidizing species generated by high-energy propellant combustion, and the resulting throat-area growth fundamentally alters the time histories of chamber pressure, thrust, and delivered specific impulse. This paper presents a nozzle-erosion reconstruction model that extracts the time-resolved throat area from coupled thrust and chamber-pressure measurements …

An Ensemble Learning-Based Approach To Quantify Post-Earthquake Functional Recovery Of A Steel Moment-Resisting Frame Inventory, Mohsen Zaker Esteghamati, Shiva Baddipalli

Civil and Environmental Engineering Faculty Publications

The quest for seismic resiliency requires designing for performance objectives beyond life safety. Functional recovery is an emerging objective often defined as the time required to restore a building’s basic functionality to the pre-event level. Nevertheless, quantifying functional recovery is a complex, computationally intensive process that is challenging to integrate into a standard design workflow. This study develops a machine learning (ML) model to map design and geometric features of steel special moment-resisting frames (SMRFs) to their functional recovery under two hazard levels: design-basis (DBE) and maximum considered (MCE) earthquakes. First, functional recovery time was quantified for an inventory of …

The Roots Of Sexual Violence In Utah: A Framework For Understanding Harm, Susan R. Madsen

Marketing and Strategy Faculty Publications

Sexual violence in Utah is not an anomaly, a private tragedy, or the result of individual deviance. It is a patterned, predictable outcome of cultural norms, social systems, and power structures that shape how people understand gender, authority, and worth. Despite Utah’s reputation for strong families, close‑knit communities, and deep religious commitment, the state continues to report higher‑than‑national‑average rates of rape, child sexual abuse, and other forms of gender‑based harm. These realities demand a deeper understanding of why violence persists—and what can be done to prevent it.

This white paper synthesizes decades of national and international research, Utah‑specific data, and …

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Goddard Laser for Absolute Measurement of Radiance (GLAMR) has been used to calibrate Earth Science optical instruments over the past ten years. The absolute radiance data is provided by a set of three broadband radiometers, consisting of one silicon, one indium gallium arsenide, and one extended indium gallium arsenide. Two such sets of monitoring radiometers associated with two different integrating spheres and a third set of radiometers used to transfer the calibration provided by NIST allow for a “round robin” intercomparison between these sets, as well as a comparison within each set in their regions of spectral overlap. Additionally, …

Geolocation Algorithms And On-Orbit Calibration For Atmospheric Waves Experiment, Eric Mckinney, Keith Blonquist, Brooke Wursten, Zach Hatfield, Pedro Sevilla, Ludger Scherliess, Connor Waite, Greg Cantwell, Harri Latvakoski, Dominique Pautet

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

The Atmospheric Waves Experiment (AWE) utilizes the Advanced Mesospheric Temperature Mapper (AMTM), built by the Space Dynamics Laboratory (SDL) and mounted on the International Space Station (ISS), to observe OH airglow emissions at approximately 87 km altitude, enabling the study of gravity wave dynamics in the mesosphere. A critical component of AWE data processing is the geolocation algorithm, which determines the latitude and longitude coordinates where each pixel’s line-of-sight (LOS) vector intersects the Earth’s atmosphere. This algorithm is essential for producing accurate data products for the corresponding spatial radiance swaths generated by the science team at Utah State University (USU). …

Applicability Of Lunar Thermophysical Models For Vicarious Calibration Of High-Temperature Thermal Infrared Sensors, Christian Molliere, Thomas Muller, Kay Wohlfarth, Marc Seifert, Joris Blommaert, Dirk Nuyts, Allison Merritt, Julia Gottfriedsen

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

Wildfire detection and characterization from space critically depend on accurate thermal infrared measurements across a wide dynamic range. OroraTech’s SAFIRE payloads feature MWIR and LWIR bands optimized for this purpose, yet the volume and power constraints of many CubeSat platforms preclude the use of onboard calibration sources. This reflects a broader limitation of current Earth observation systems: the absence of robust calibration and validation methodologies at high brightness temperatures relevant to active fires.

We evaluate the potential of using thermophysical models (TPM) of the lunar surface as a vicarious calibration reference for calibration transfer between instruments. The Moon reaches surface …

Arcstone: Calibration Of Lunar Spectral Reflectance From Space, Cindy Young, M. Cooney, A. Thurston, L. Morrill, N. Ryan, M. Banchy, C. Stimson, B. Magill, J. Campbell, C. Roithmayr, R. Swanson, G. Kopp, T. Stone, C. Lukashin

The Characterization and Radiometric Calibration for Remote Sensing Annual Meeting (CALCON)

In remote sensing of the Earth system, accuracy is key for developing reliable, long-term environmental data records built from data collected by multiple instruments, for quickly detecting trends in the quantities being observed, and for determining the confidence with which conclusions can be drawn from those data. For sensors measuring light in the reflected solar wavelengths from Earth orbit, measurement accuracy has historically been limited by the techniques used in calibration (e.g., using onboard lamps and/or solar diffusers that increase instrument mass/complexity and degrade over time, or viewing ground sites through the Earth’s atmosphere, requiring an additional correction, etc.). The …

A Provable Semi-Infinite Programming Approach For Solving Constrained Dynamic Games, Tyler C. Gardner, Matthew W. Harris, Logan Lancaster

Mechanical and Aerospace Engineering Student Publications and Presentations

Many engineering problems must account for the non-cooperative decisions and actions of multiple players. These problems can be modeled within a game-theoretic framework. The approach herein is to model such problems as mathematical games, convert them to semi-infinite programs, and utilize a semi-infinite program solver whose output is provably an ϵ-optimal Nash equilibrium. The approach is successfully benchmarked on two low-dimensional problems. Two types of higher-dimensional linear quadratic dynamic games are then investigated: ones where each player’s problem is convex and ones where at least one player’s problem is nonconvex. Within each type, variations based on information structure, control …

Seed Endophyte Bacillus Atrophaeus Colonizes Root And Shoot Tissues Providing Antifungal Activity During Wheat Seedling Establishment, Anagha Wankhade, Zhiting Xu, Ashlynn Clark, David Britt

Biological Engineering Student Research

Seed-associated endophytes become active during germination, playing important roles as early colonizers of plant tissues and contributing to plant health while residing in a protective niche. In this study, we characterized a wheat-derived bacterial isolate, JunSE1L, to determine its functional traits and ecological role in the plant microbiome. The isolate was identified as Bacillus atrophaeus based on 16S rRNA analysis. JunSE1L exhibited nutrient-dependent plasticity in colony architecture, forming robust hydrophobic biofilms and pellicles under rich nutrient availability while swarming and forming thin, often dendritic colonies under defined nutrition. JunSE1L produced highly surface-active compounds that lowered the surface tension of water …

Data-Driven Lpv Modeling Via Parametric Dmd And Predictive Control Of Highly Flexible Aircraft, Larry Catalasan, Tianyi He, Weihua Su

Mechanical and Aerospace Engineering Student Publications and Presentations

This paper presents a method of data-driven parametric dynamic mode decomposition (p-DMD) to derive a linear parameter-varying reduced-order model (LPV-ROM) and predictive control for the nonlinear aeroelasticity of highly flexible aircraft. It directly uses the data snapshots obtained at varying flight conditions and encodes a nonlinear model’s polynomial dependency on flight conditions to produce a polynomial-dependent LPV-ROM. The modeling method can handle not only equilibrium flight conditions but also continuously varying flight conditions. In numerical studies, the proposed data-driven p-DMD modeling is applied to a highly flexible cantilever wing perturbed around equilibrium conditions and a flexible aircraft with time-varying angles …

Open Space Management Planning: A Framework And Case Study From Eagle Mountain City, Utah, Nathan K. Shumway

All Graduate Reports and Creative Projects, Fall 2023 to Present

Open Space Management Plans (OSMPs) are increasingly used by municipalities to guide the long-term stewardship of natural lands; however, little formal guidance exists regarding how these plans are structured, developed, or organized in practice. While numerous OSMPs are publicly available, their compositional logic, procedural workflows, and thematic priorities remain largely undocumented within academic literature. This study addresses that gap through a qualitative document analysis of fifteen publicly accessible OSMPs from the western United States, published between 2015 and 2024.

Using manual matrix-based coding in Microsoft Excel, each plan was analyzed through three lenses: structural composition, procedural development, and thematic content. …
