Multiple Variable Regression Assignment, Sam Loyd

Distinguished Student Scholarship Collection

This paper applies multiple linear regression analysis to examine whether life outlook and sociability predict happiness. Using a dataset of 38 observations, the study employs IBM SPSS to conduct exploratory data analysis, assess regression assumptions, and evaluate model validity. Key assumptions—including linearity, homoscedasticity, independence of residuals, multicollinearity, normality, and the presence of influential outliers—are systematically examined using statistical tests and visual diagnostics. While some deviations from normality and potential nonlinear patterns are identified, the analysis proceeds based on sample size considerations and overall assumption adequacy. Results indicate that the regression model is not statistically significant and explains only a small …

Gravity Compensation, Carter Glover, Siyuan Zhou

Senior Project

This project focused on the design, analysis, and testing of an air-bearing gravity compensation testbed intended to simulate reduced-friction motion for space-related applications. Computational Fluid Dynamics (CFD) simulations were conducted to evaluate airflow characteristics, pressure distribution, and bearing performance under various operating conditions. The design was refined to improve load support, stability, and airflow efficiency while maintaining manufacturability. Experimental testing and simulation results were compared to assess system performance and validate design assumptions. The completed testbed demonstrates the feasibility of using air bearings to create a low-friction environment suitable for motion testing and gravity compensation studies.

Optical Force/Torque Sensor, Kyle Sweeney, Ian Unruh

Senior Project

This project presents the design, development, and testing of a low-cost optical force/torque sensor for Skyforge, an autonomous robotic system intended for in-space construction.

Skyforge—Autonomous Robot For On-Orbit Assembly Of Space Structures, Kate Keeler, Garrett Farnham, Logan Trier, Ainsley West

Senior Project

As interest in deep space exploration and satellite communications increases around the world, the need for large orbital structures such as space stations, solar fields, and telescopes increases in parallel. Current methods include monolithic modular assembly, expanding deployable structures or requiring Extra-Vehicular Activities, all of which are costly and highly specialized. This paper proposes a form of robotic on-orbit assembly for structures beyond the size constraints of the launch vehicle. The SkyForge system consists of a launch capsule containing construction materials and a pair of tripedal robots, identical in form and task. These robots would autonomously locomote on, and assemble …

Navigating Sustainable Burial In Southern Nevada, Kristen Gibson

Calvert Undergraduate Research Awards

Navigating Sustainable Burial in Southern Nevada investigates the accessibility of environmentally conscious end-of-life options for individuals throughout the region. Sustainable burial practices, including green burial, water cremation, and natural organic reduction, provide alternatives to traditional burial and cremation methods. Research was conducted through an analysis of Nevada statutes, local reporting, funeral service resources, and public discussions related to sustainable burial. The research revealed that although Nevada expanded legal recognition of sustainable burial by legalizing natural organic reduction, public access to clear information and available services remains limited. These findings informed the creation of a choose-your-own-adventure booklet designed to translate legal …

Code And Consequences: How Fraud Detection Algorithms Criminalize Welfare, Michele E. Gilman

All Faculty Scholarship

This article investigates the growing use of automated fraud detection systems in public benefits programs, focusing on how these technologies have intensified the surveillance and criminalization of low-income individuals. Across the globe, government agencies deploying fraud detection algorithms have wrongfully accused thousands of people of committing fraud, with devastating consequences, including bankruptcy, job loss, and psychological trauma. These algorithmic systems operate as opaque “black boxes,” fueled by historical biases against the poor and largely unaccountable to the individuals they affect. Meanwhile, the private vendors that develop the algorithms reap massive profits from unfulfilled promises of efficiency and cost savings.

The Kaczmarz Algorithm In Hilbert C∗-Modules, Daniel Alpay, Chad Berner, Eric S. Weber

Mathematics and Statistics Faculty Research & Creative Works

The Kaczmarz algorithm in Hilbert spaces is a classical iterative method for stably recovering vectors from inner product data. In this paper, we extend the algorithm to the setting of Hilbert C^∗-modules and establish analogues of its effectiveness in both finite-dimensional and stationary cases. Consequently, we demonstrate that continuous families of elements in a Hilbert space can be uniformly recovered using the Kaczmarz algorithm. Additionally, we develop a normalized Cauchy transform for continuous families of measures and use it to provide sufficient conditions under which standard frames in Hilbert C(X)-modules can be generated by the Kaczmarz algorithm and …

A Fully Discrete Decoupled Scheme And Applications For Non-Isothermal Two-Phase Flow Model With Different Viscosities And Thermal Diffusivities, Jian Li, Chunhao Chen, Xiaoyong Chen, Rui Li, Xiaoming He

Mathematics and Statistics Faculty Research & Creative Works

To study natural convection problems in two-phase flows, a non-isothermal two-phase flow model incorporating differential viscosities and thermal diffusivities is considered and analyzed via the phase-field method. This modeling framework involves the Multiphysics coupling of the Cahn-Hilliard phase field equations, heat transfer equation, and Navier-Stokes equations, resulting in a strongly nonlinear system. To efficiently solve the sophisticated system, we develop, analyze, and demonstrate a decoupled linear fully discrete scheme, which leverages the invariant energy quadratization strategy for the Cahn-Hilliard phase field system, the artificial compressibility method without artificial pressure boundary condition, an explicit-implicit treatment of nonlinear terms, and the addition …

Data were collected by video-recording two pairs of pupils collaborating in each session, as well as a whole-class session at the end of the second session. The pupils’ written work during the sessions was also collected as data. The classroom sessions were designed based on principles from the Theory of Didactical Situations. Data were analysed using a dialogical approach and based on theory for multiplicative structures and semiotic representations. The study shows that …

Learning About Human Mathematical Dialogue From Dialogue With Chatbots: Babbling, Gargling And Funnelling, Ingólfur Gíslason

The Mathematics Enthusiast

In this study, I explore mathematics teaching-learning dialogues between preservice teachers and a chatbot (ChatGPT) with the aim of increasing our understanding of human mathematics teaching-learning dialogues. The dialogues contain wrong solutions (as determined by the preservice teachers), and the teachers try to get the chatbot to reconsider its answers without giving away the answer. The chatbot’s solution attempts are interpreted through and against the concepts of babbling (imperfect efforts to express thought) and gargling (imitation of surface form of expressions), and the dialogues are analyzed by considering whether and how the preservice teacher and the chatbot reach joint attention. …

Hidden Diversity In A Clonal Endemic: Insights Into Clematis Socialis From A Population Genetics Perspective, Joanna M. Lapoint

Theses

Clematis socialis (Kral) is a rare, federally endangered perennial species restricted to a small number of fragmented populations in Alabama and Georgia. The species exhibits extensive clonality and limited sexual recruitment, characteristics that complicate expectations regarding genetic diversity and population connectivity. Despite its conservation significance, genome-wide assessments of population structure have been lacking. We used genotyping-by-sequencing (GBS) to generate a genome-wide SNP dataset for 170 individuals sampled from six natural populations. Population structure and genetic differentiation were evaluated using Bayesian clustering, analysis of molecular variance (AMOVA), pairwise FST estimates, and network-based visualization. Analyses revealed strong genetic structuring among populations and …

Storm-Drains As Ecosystems, Victoria E. Kennedy, Curtis Jang, Darlene Panvini

SPARK Symposium Presentations

Stormwater drains and culverts are installed across urban spaces to direct surface water and allow for proper drainage and prevent flooding and erosion. These structures and the water that they carry can provide unintended opportunities to wildlife. Previous research has shown that local ecosystems may utilize and adapt around these culverts in many ways. They can serve as habitats, connect fragmented habitats separated by roads or human traffic, serve as drinking spots, and promote biodiverse plant growth. This project aims to analyze these often-overlooked spaces as ecosystems themselves, so that we can learn more about their impact and significance.    Key …

By fostering university partnerships and providing summer research opportunities, RET aligns with the National Rural Research Agenda’s (NREA) priorities of enhancing community relationships and bolstering teacher preparation, recruitment, and retention. Findings indicate that participation in RET boosts teachers’ curricular skills, professional networks, and …

Sapientia Ex Machina: Engaging Ai As A Meaning-Making Tool For Philosophical Practice, Austin M. Pritchett

SPARK Symposium Presentations

This paper sets out to examine whether a Large Language Model can serve as a genuine interlocutor in philosophical inquiry. With a grounding in the phenomenology of Maurice Merleau-Ponty, and in conversation with other works in philosophy on AI, language, and the mind, the author determines the extent to which an AI's contributions to conversation can be said to participate in understanding and meaning-making rather than merely simulate it, thereby making evident the extent to which it is useful in philosophical practice.

Situating Ai Within The History Of Technological Adaptation In Law, Karin Mika

SLU Law Journal Online

This Article argues that the current anxiety surrounding generative artificial intelligence (AI) in the legal academy is the latest iteration of a recurring historical cycle. By examining the introduction of other technological enhancements in the law, the author demonstrates that each technological shift was initially met with skepticism regarding the potential loss of critical thinking skills. However, history shows that these tools ultimately pushed the profession away from a focus on mechanical form and toward a deeper engagement with substantive analysis and strategic advocacy. Rather than posing an existential threat, AI represents a logical next step that can automate the …

Revisiting The Missed Pigouvian Opportunity Of The First Industrial Revolution: A Carbon-Based Pigouvian Tax On Ai, Haozheng Jiang

SLU Law Journal Online

As artificial intelligence (AI) reshapes the economy with comparative speed and scope as during the First Industrial Revolution, policymakers face a familiar dilemma: how to preserve technological progress while addressing its negative externalities. This article proposes a uniform, carbon-based Pigouvian tax on AI as a practicable and forward-looking solution to correct one of AI’s most readily measurable negative externalities without stifling innovation. Drawing on lessons from existing carbon-pricing systems, this article contends that such a tax should be designed with flexibility and transparency to promote both effectiveness and political feasibility. Properly structured, the tax would not deter AI development but …

Policy Design, And The Repeal Of Ghana’S Emissions Levy Act: A Multiple Streams Framework Analysis, Anthony Amotoe-Bondzie

Collected Student Papers

Ghana’s 2023 Emissions Levy Act (Act 1112) imposed charges on large industrial emitters and vehicles, intending to internalize pollution costs and raise government revenue. This study applies to Kingdon’s Multiple Streams Framework (MSF) to explain the policy’s rapid repeal. Drawing on legislative texts, official reports, and media accounts, it categorizes influences into the problem (rising living costs), policy (design features), and politics (stakeholder mobilization) streams. Key findings reveal that the levy’s mixed design, a per-ton CO₂ fee on industry combined with a flat vehicle ownership tax, undermined its climate rationale and appeared more as a revenue grab. Implementation gaps exacerbated …

Closing The Loop In Sustainable Fashion: Recycling Textile Waste And Its Environmental, Social, And Consumer Impacts, Anthony Amotoe-Bondzie

Collected Student Papers

Fast fashion has intensified textile waste, emissions, and social inequities across global supply chains. This study examines sustainable fashion frameworks and the role of textile recycling in advancing circularity. It employes a qualitative integrative literature review synthesizing interdisciplinary research on waste streams, recycling technologies, policy instruments, and consumer behavior. However, advanced recycling technologies offer environmental benefits but remain limited in scale. Nonetheless, rising consumption offsets efficiency gains, while economic and behavioral barriers hinder systemic change. Technological innovation alone is insufficient; circular design, regulatory enforcement, and reduced overproduction are essential for sustainable transformation.

Sequences That Do Frame Reconstruction, Chad Berner

Mathematics and Statistics Faculty Research & Creative Works

Frames allow all elements of a Hilbert space to be reconstructed by inner product data in a stable manner. Recently, there is interest in relaxing the definition of frames to understand the implications for stable signal recovery. In this paper, we relax the definition of a frame by allowing the operator in the frame decomposition formula to not be invertible. We provide a complete classification of sequences that allow this decomposition via a type of frame operator. In addition, we provide several examples of sequences that allow this reconstruction property that are not frames and illustrate in which ways they …
