Tuning And Performance Of Pid Controlled Low Complexity Systems, Timothy Evans

Honors Theses

Proportional integral derivative (PID) controllers are used for precise position and orientation control in systems such as autonomous underwater vehicles (AUVs). This project supports the University of Southern Mississippi’s (USM) Robotics Club’s RoboSub AUV effort by developing, troubleshooting, and manually tuning PID controllers to characterize tracking performance and settling time across systems of increasing complexity. Initially, the project hypothesized that tracking performance would be reduced and settling times would increase as system complexity advanced from one degree-of-freedom (DOF) to two DOF. However, prior research was found that suggests that for small disturbances around an equilibrium state, separate PID-controlled DOFs can …

Optimizing Auv Perception For Competitive Underwater Robotics: Analyzing Performance And Simplicity Of Machine Vision Hardware, Joseph King

Underwater robotics is a growing field with many practical applications, such as pipeline and offshore structure monitoring, deep sea mining, mine reconnaissance/removal, and marine environmental monitoring. USM’s Robotics Club will participate in the international RoboSub competition, where student-led teams build autonomous underwater vehicles (AUVs) that perform a variety of tasks within a pool requiring camera-based object detection. This project analyzes affordable hardware and software options for providing machine vision to USM’s future RoboSub AUV. The performance of an ESP32-CAM microcontroller, Raspberry Pi 5, and Jetson Orin Nano single-board computers running FOMO and YOLO object detection models was compared. These models …

Tough Love Or Just Tough?: The Effect Of Juvenile Military Bootcamps On Adolescent Externalizing Behaviors, Paris Labadie

Honors Theses

Externalizing behaviors, which are mental health problems manifested as outward behavior, have negative impacts on the environment and relationships (Liu, 2004). They include traits such as impulsivity, aggression, and substance use. Externalizing behaviors are more common in justice-involved youth compared to those who were not involved. Interventions for justice-involved youth, such as military boot camps, offer an alternative to incarceration and provide rehabilitation opportunities and routine. Theoretical research suggests military boot camps are problematic, citing the ineffectiveness of “scared straight” tactics. To date, there are few studies examining changes because of completing boot camps. There are also no studies examining …

Who Then Can Be Saved? A Discussion Of Views Within The Christian Tradition Concerning The Salvation Of The Non-Christian, Logan A. Davis

Honors Theses

This thesis argues that, contrary to popular conception, the Christian Tradition is not strictly exclusivist in its understanding of salvation or in its assessment of the fate of the non-Christian but rather displays a rich diversity of views. Both the Christian Tradition and the Christian scriptures are characterized by a certain ambiguity on this issue; although a definitive answer may exist, it is not easily identifiable. Given this ambiguity, the study presents a representative spectrum of theological positions within the Christian Tradition and analyzes their respective treatments of the salvation of the non-Christian. In doing so, it seeks to provide …

Knowledge Distillation From A Large Vision-Language Model To Compact Students For Architectural Floor Plan Understanding, Kiran Silwal

Honors Theses

In this research, the use of a large vision-language model to train smaller, deployable models for architectural floor plan question answering is investigated. Reading a floor plan today requires either a human expert or a paid query to a proprietary model, and neither option is practical for real-estate platforms that must process thousands of units at scale. To address this problem, a knowledge distillation approach is employed in which a large teacher model (GPT-4.1-mini) generates labeled question-answer pairs from floor plan images, and smaller student models learn from those labels. The teacher produced 37,027 labeled pairs from 12,343 floor plan …

An Exploratory Analysis Of Student Attitudes Towards Punishment: Punitive Vs Rehabilitative Orientations, Leah Johnson

Honors Theses

This study examined differences in punishment orientation among undergraduate students, paying particular attention to variations across academic major, degree progression, and connectivity to law enforcement and corrections. This study explored how individual characteristics may influence attitudes toward crime and appropriate punishment. Data were collected through surveys which were administered in person to students enrolled in criminal justice or social science courses at the University of Southern Mississippi. Participants were asked to rate their level of agreement on a variety of statements regarding punishment. These responses were used to calculate punitive and rehabilitative orientation scores. Statistical analyses were conducted to test …

Ai-Assisted 3d Pre-Visualization: Streamlining Animatics For Filmmakers, Nishit Thapa

Honors Theses

Pre-visualization is a core part of film pre-production. Creators use it to test blocking, lighting, camera movement, and spatial relationships before committing to a shot. Despite this, three-dimensional pre-visualization remains out of reach for many entry-level filmmakers, as the software is expensive and takes substantial time to learn.

Recent AI developments have produced generative systems capable of creating highly re-alistic imagery and video from text prompts. These systems open new possibilities for visual sto-rytelling but are not built for the iterative, hands-on process that pre-visualization requires, where creators must adjust scene parameters, camera logic, and spatial configurations throughout.

Digital Preservation Policies In University Libraries: A Content Analysis, Ramsey Mcmanus

Honors Theses

In an increasingly digital world, libraries continue to expand their digital collections. As these collections grow, librarians must work to ensure that these digital materials remain accessible over time. Having clearly articulated digital preservation policies helps libraries define their preservation commitments and establish guidelines for preservation actions. This study examines how university libraries approach digital preservation through their policies, focusing on those that are publicly available and accessible online. The content of these policies is evaluated against commonly recognized elements of digital preservation planning, including preservation scope, metadata practices, integrity checking, storage redundancy, and format migration. These criteria are derived …

Rethinking News Classification Through A Multi-Dimensional Framework, Luana De Jesus Ferreira

Honors Theses

This thesis proposes a multi-dimensional framework for news classification that evaluates articles across three independent dimensions: headline accuracy, language neutrality, and content reliability. These dimensions produce both a continuous reliability score and a five-tier interpretive scale, while additionally classifying articles by genre and topic. To operationalize this framework, a structured annotation protocol was developed and applied to a dataset of 373 news articles drawn from 79 outlets spanning a wide range of contemporary media ecosystem. A binary Logistic Regression classifier trained on the ISOT Fake News Dataset was then evaluated against this dataset to examine how a model trained on …

Evaluating The Environmental Parameters Impacting Spawning Movement Of Gulf Sturgeon (Acipenser Desotoi) In The Bouie River System., Olivia St. Germain

Honors Theses

The anadromous Gulf Sturgeon (Acipenser desotoi) is federally listed as “threatened” and is natal to seven rivers from Louisiana to Florida. Only one spawning reach for Gulf Sturgeon natal to the Pascagoula River has been verified via the collection of eggs and larvae; a reach of the lower Bouie River. This reach is anthropogenically modified by four gravel mining formations, hereafter referred to as pits. The greater depths associated with this area have prompted previous researchers to suggest that Gulf Sturgeon may over-summer in pit formations instead of migrating to downstream holding areas in the Pascagoula River after spawning. The …

Public Opinion Of And Faith In The U.S. Supreme Court, Allee Gay

Honors Theses

The US Supreme Court has been historically trusted as an impartial arbiter of the Constitution. However, in 2022 the level of public trust in the Supreme Court dropped to a historic low, and faith in the institution has not recovered in the following years. Previous research demonstrated that Supreme Court decisions can influence public opinion and suggested that the Dobbs v. Jackson Women’s Health Clinic can be blamed for this decline. Further research proved that the President’s role in appointing justices can have an effect on the perception of the Court. This study examines both the reactions to controversial cases …

Financial Fraud In Mississippi Public Agencies: Case Studies Of Control Failures And Implications On Civic Engagement, Gracie Sullivan

Honors Theses

This study analyzes the relationship between financial fraud in Mississippi public institutions and its potential impact on civic engagement. While the existing literature explores the mechanics of fraud through frameworks such as the Fraud Triangle and the role of internal controls in preventing misconduct, limited research examines how government corruption influences civic disengagement, particularly in Mississippi. Using a quantitative, comparative research design, this study examines the relationship between major public financial fraud cases and voter turnout in case-linked and comparison counties. These cases include the Mississippi TANF welfare fraud, the Department of Corrections bribery case, and the misuse of funds …

A Comparative Legal Analysis Of The English And Scottish Reformations, Erin Hanson

Honors Theses

This thesis examines the legal and institutional mechanism that contributed to the decline in Catholicism in early modern England and Scotland during the Reformation period. By analyzing statutory developments, ecclesiastical court structures, and enforcement practices, it compares how each kingdom implemented religious reform and regulated religious conformity. Rather than focusing solely on theological differences, this study emphasizes the role of legal structure and legal institutions in shaping religious governance.

Chapter I outlines the historical and legal background of the English and Scottish Reformations. Chapter II examines prior literature, and Chapter III states the methodology used in this study. Chapter IV …

Does Sponsorship Context Matter? Comparing Local And National Sponsorship Effects On Consumer Behavior, Kathryn Flock

Honors Theses

Sponsorship use has become increasingly important as a marketing strategy for influencing consumer perceptions of the sponsoring company. This, in turn, establishes consumer relationships that result in favorable behavioral intentions. While prior research has examined national and global sponsorships, there is limited research on the differences between national and local sponsorships and how these differences could influence consumer perceptions and behavioral intentions. The purpose of this study was to examine how local or national sponsorship affects consumer perceptions, including sincerity, trust, attitude toward the sponsor, and behavioral intentions.

A mixed-methods approach was employed for this study. Study 1 used qualitative …

Bodies As Vessels: (Re)Production, Consumption, And Female Identity In The Handmaid’S Tale And Dawn, Shelby Clark

Honors Theses

This honors thesis examines how reproduction and food are used to signify power and impact female identity in Margaret Atwood’s The Handmaid's Tale and Octavia Butler’s Dawn. Both feminist dystopian novels portray societies that secure futurity through the commodification and management of women's domestic labor. The protagonist of each novel, Offred in The Handmaid's Tale and Lilith in Dawn, is responsible for ensuring the survival of humanity through forced reproduction and is additionally expected to produce or manage food. In this thesis, I argue that in both novels, female identity is reclaimed and affirmed as separate from a commodified state …

Icarus’S Fall: Villainization In Wicked, Star Wars, And The Untamed, Laura Renfroe

Honors Theses

When looking back on the most beloved, yet infamous, villains of popular culture, one can note an abundant rise of prequels and backstory-driven media exploring the paths that villain characters take that lead them to their tragic fall. Some of those stories include John M. Chu’s Wicked, George Lucas’s Star Wars: Episode III: Revenge of the Sith, and Chen Jialin and Zheng Weiwin’s The Untamed, each of which explores protagonists who are labeled as “wicked” and depicted as fallen to the “dark side.” While these characters are often studied in existing literary research, there have yet to be explicit ties …

Environmental Degradation And Food Systems In Ghana: Gold Mining And Synthetic Pesticides, Da'mirah Vinson

Honors Theses

This research examines the relationship between environmental degradation and food systems in Ghana. Although sociological research has explored how extractive practices like gold mining dispossesses farmers of land (Gilbert and Albert 2016; Agariga 2021; Kwang and Blagogie 2025), the consequences for food sovereignty and security remain understudied. Research that considers food and land from a sociocultural perspective is even more limited. My research addresses these gaps by asking: How do environmental degradation practices—specifically gold mining and chemical use—affect food production, distribution, and security in Ghana? And how does the decline of arable land reshape cultural food identity? To explore these …

Toward Completeness Theorem For Guarded Kleene Algebra With Tests, Hung Pham

Honors Theses

Code refactoring is a fundamental practice in software engineering, in which a program is restructured without changing the actions it performs and the results it produces. To carry out refactoring with confidence, one requires a formal method for verifying that two programs are equivalent. Guarded Kleene Algebra with Tests (GKAT) provides such a framework, an algebraic system designed to reason about a natural class of programs, namely those in which every branch and loop is governed by a Boolean condition, such as if–else and while statements. Central to GKAT is a finite set of algebraic axioms for deriving program equivalences. …

Temperature-Dependent Optical Properties Characterization Of Thermophotovoltaic Selective Emitter (4h– Sic, Aln Ceramic, And Aln/Al2o3), Po-Chao Huang

Honors Theses

Thermophotovoltaic (TPV) systems convert thermal radiation into electricity, and their efficiency depends strongly on the temperature-dependent optical response of the emitter materials. To support the design of high-temperature selective emitters, we characterized the thermo-optical properties of aluminum nitride ceramic (AlN), silicon carbide (4H– SiC), and aluminum oxide on aluminum nitride (AlN/Al2O3) thin film/substrate pairs, as a promising example of a bilayer emitter. Spectroscopic ellipsometry measurements from 240 nm to 2500 nm were performed while heating samples from room temperature to 600 °C. Using general oscillators modeling, we established accurate temperature dependent optical models consistent with literature values. Increasing temperature revealed …

Leveraging Machine Learning Techniques To Identify Catastrophic Outliers In Photometric Redshift Estimates, Jason Yoo

Honors Theses

Leveraging the unprecedented data volumes from modern astronomical surveys, this work addresses the critical challenge of identifying catastrophic outliers (COs) in photometric redshift (photo-z) estimates. Reliable redshift estimation is essential for precision cosmology, yet COs (galaxies with severely erroneous photo-z) can introduce significant systematic bias. We develop and evaluate two machine learning approaches for robust CO identification: a multilayer perceptron (MLP) utilizing photo-z point estimates and probability distributions, and a convolutional neural network (CNN) leveraging raw 5-band photometric images. Using datasets emulating LSST conditions, we demonstrate that the MLP model achieves high accuracy and stability across redshift bins, correctly identifying …

From Sediment To Mangrove: Tissue-Specific Metal Accumulation In Red Mangroves Of Southeastern Florida, Sophie Welch

Honors Theses

Coastal wetlands near industrialized waterways face increasingly heavy‐metal contamination, posing risks to benthic communities and food webs. Mangroves can influence metal cycling through sediment trapping, root‐zone sequestration, and internal physiological regulation, yet their effectiveness in urbanized systems remains debated. This study quantified concentrations of 17 heavy metals in sediments and mangrove tissues from four sites near Port Everglades, Florida, examined tissue‐specific partitioning, spatial and temporal contamination patterns, and examined the mangroves’ role in mediating metal loads. Ecological risk metrics identified STB as a contaminant hotspot with exceedances of TEL values across multiple elements (Ni, Pb, and Zn) as well as …

Hegemonic Microtonality: Decolonizing The Soundscape Of Music Theory Pedagogy, Ash K. Wetty

Honors Theses

This thesis examines how Western music theory pedagogy—long organized around tonal and twelve-tone equal-temperament frameworks—structures both what is taught and how students are trained to listen. Through a literature review tracing the historical construction of tonal universality in undergraduate curricula, the project argues that dominant models of music theory reproduce broader epistemic hierarchies inherited from Western conservatory traditions. Situating these histories within my own experience as a student navigating institutional listening norms, the thesis combines critical self-reflection with ethnographic research conducted across five liberal arts institutions, including the CBB consortium and JanPlan research at Wesleyan University and Amherst College. Rather …

Near And Dear: How Proximity To Amenities Shapes Land Value In Maine, William Kopans

Honors Theses

Residential land values reflect the benefits of accessibility to amenities as well as the costs associated with commercial activity. This trade-off is particularly important in Maine, a predominantly rural state where most households rely on automobiles to access employment, retail, and civic amenities. Drawing on hedonic theory, I analyze how households value proximity to public and private amenities located within downtowns and shopping centers. Using parcel-level transaction data from ATTOM combined with amenity data from OpenStreetMap, I construct a novel approach that differentiates downtown and shopping center clusters across the state. The findings demonstrate that properties located immediately adjacent to …

Metamorphosed Components In Cv Chondrites Camel Donga 003 And Camel Donga 040 As Evidence For Varying Degrees Of Metamorphism Within The Parent Body, Kathryn E. Stone

Honors Theses

The CV carbonaceous chondrites are a group of primitive stony meteorites that record early solar-system evolution processes. They are typically of low metamorphic grade, though some metamorphosed CVs have recently been found. Two CV chondrite breccias, Camel Donga 003 (CD 003) and Camel Donga 040 (CD 040) consist of multiple lithologies. CD 003 consists of three lithologies, one of which – Lithology C – has been metamorphosed to petrologic type ~3.7 (Alevy et al. 2025). CD 040 consists of two lithologies, one of which is metamorphosed to petrologic type 3.7 (Dunn and Alevy, 2024; Dunn et al. unpublished). Both samples …

Ultra-Processed Or Ultra-Addictive? A Demand-Based Redefinition Of Ultra-Processed Foods, Braden Jondro

Honors Theses

Ultra-processed foods now comprise the majority of the U.S. food supply and have been directly associated with 32 chronic diseases including obesity, cardiovascular disease, cancer, and diabetes. Current classification systems such as NOVA provide a useful framework for identifying food processing, but rely on broad and subjective categorizations that may not capture the mechanisms most closely associated with promoting persistent overconsumption. In particular, existing classification systems remain limited in their ability to evaluate addiction-like behaviors associated with highly processed foods, including persistent purchasing patterns, reinforcement effects, and substitution responses. This paper introduces the Ultra-Processed Food Intensity (UPFI) index, an objective, …

Three-Photon Rydberg Eit Lineshape Analysis In Rubidium, Jackson Lake

Honors Theses

Electromagnetically Induced Transparency detection of high-lying Rydberg states in room-temperature rubidium vapor was investigated using a four state ladder-type excitation scheme with light provided by three External Cavity Diode Lasers (ECDLs) at 780 nm, 776 nm, and 1266 nm. This detection technique was studied by characterizing the lineshape parameters of the EIT transmission peak, specifically the height, width and area of the transparency window as functions of the dressing and coupling laser powers. With the goal of characterizing the linewidth of the transmission signal, a confocal etalon was built and implemented in the optical setup to perform frequency calibration of …

Analyzing Rydberg Atoms Of Rubidium At Room Temperature: Applying Electromagnetically Induced Transparency, Bridger Stiles

Honors Theses

This thesis describes an experimental exploration of electromagnetically induced transparency (EIT) in atoms of 85Rb using a new MOGLabs external cavity diode laser. A two-step ladder technique of EIT was applied using a 5S_1/2→5P_3/2 probe transition and 5P_3/2→nD_5/2 coupling transitions. Significant apparatus tuning was done, including developing a reliable procedure of regulating frequency and scanning the coupling laser over a sufficient mode-hop free range. A Doppler-reduced technique was applied by counter-propagating the probe and coupling beams through the Rb vapor cell. EIT signals were collected at various probe and coupling laser powers to analyze changes in signal size and linewidth. …

Between Commodity And Culture: Tea Advertising As A Site Of Imperial Ideology And Anti-Colonial Resistance In India, Sydney Pascal

Honors Theses

Between the late nineteenth century and Indian independence in 1947, tea advertising became a key site through which imperial authority and Indian nationalism were negotiated. Drawing on advertisements, trade journals, and visual marketing campaigns produced from the 1880s through the 1950s, this honors thesis argues that tea advertising was a cultural and political mechanism through which the British Empire attempted to normalize imperial consumption and legitimize colonial authority. British campaigns framed tea as modern and routine while obscuring the exploitative labor systems and landscape transformations that sustained plantation production in Assam. As nationalist movements expanded in the early twentieth century, …

A Critical Discourse Analysis Of Racial Justice In Virginia Higher Education, Abigail Green

Honors Theses

This honors thesis examines the extent to which public Virginia higher education institutions engage their institutional histories in leadership rhetoric when responding to the Trump administration’s anti-diversity, equity, and inclusion (DEI) policies. Employing a Critical Discourse Analysis (CDA) following Mullet’s (2018) seven-step framework with an inductive coding approach and grounded in rhetorical history theory, this study analyzes official statements from the Offices of the President and Provost across four case study institutions: the University of Virginia (UVA), George Mason University (GMU), the College of William & Mary (W&M), and Longwood University (LU). Data sources span two time periods: May 2020 …

From Shock To Routine: The Evolving Impact Of Shutdown-Related Sentiment On Stock Markets, Yiran Shao

Honors Theses

To address gaps in existing research, this paper selects two U.S. government shutdown periods, 2018-2019 and 2025, as research samples to explore the effect of policy uncertainty on sentiment. This paper primarily analyzes the following two research questions.

First, what is the correlation between government shutdown-related sentiment during the shutdown period and daily market fluctuations? Specifically, can the sentiment index constructed from shutdown-related news effectively predict the next-day stock return during the event period?

Second, does the market have a learning effect? That is, between 2018-2019 and 2025, has the relationship between shutdown-related emotions and market outcomes weakened, shortened the …
