Integrated Framework For Tsn-Enabled Ot Networks And Scalable Edge Computing To Enable Real-Time Feedback Loop, Taposh Kumer Sarker

Open Access Theses & Dissertations

The advent of Industry 5.0 envisions smart manufacturing characterized by human centricity, sustainability, and systemic resilience. Realizing this vision requires the seamless convergence of Information Technology (IT) and Operational Technology (OT) networks. However, integrating massive, stochastic IT edge computing workloads with deterministic physical control loops introduces severe architectural friction, inherently threatening the safety guarantees required by industrial machinery. To resolve this fundamental incompatibility, this dissertation proposes the Edge-Augmented Real-Time Industrial Control System (EA-RICS).

EA-RICS is a comprehensive, multi-layered architecture designed to dismantle systemic bottlenecks across the physical data plane, the centralized control plane, and the edge operating system. First, the …

Development And Evaluation Of Alternative Mandrel Materials For The Fabrication Of In-House Silicone Vascular Models, Cole Capitani

Master's Theses

Dr. Kristen Cardinal’s Tissue Engineering Laboratory at California Polytechnic State University, San Luis Obispo develops tissue-engineered blood vessel mimics (BVMs) for preclinical testing of neurovascular devices. These BVMs are reliant on silicone vascular models that define the vessel geometry, support endothelial cell attachment, and allow devices to be evaluated in a controlled in vitro environment. Previous work in the lab established injection molding as a viable method for fabricating silicone vascular models and utilized acrylonitrile butadiene styrene (ABS) for sacrificial mandrels. However, this workflow relied on the use of acetone for mandrel dissolution, required single-use mandrels, had extended post-processing times, …

When Does Emigration Reduce Domestic Economic Activities? Evidence On The Loss Of Management Capacity From A Visa Lottery, Marup Hossain, Ahmed Mushfiq Mobarak

Discussion Papers

Economic development is often conceived as structural transformation and migration out of rural agriculture (Lewis, 1954; Fei & Ranis, 1964). Understanding development therefore requires us to identify how rural economies transform in response to emigration. We study how international migration reshapes domestic economic activity in origin households using a randomized visa lottery that gave Bangladeshi men job opportunities in Malaysia. Winning the lottery raises total household income through remittances, but income earned in Bangladesh declines due to contractions in nonfarm business activity. In contrast, crop income remains stable despite large reductions in agricultural input expenditures, because farming gets delegated through …

Secure And Compassionate Dementia Care: Non-Intrusive Remote Monitoring Of Falls, Wandering, And Agitation, Awan-Ur- Rahman

Master's Theses

Alzheimer’s disease and related dementias (ADRD) present significant safety challenges, as affected individuals may experience falls, wandering, agitation, and a progressive decline in independence. Although continuous monitoring can enable timely intervention, many existing systems rely on cameras or wearable devices, which may introduce concerns related to privacy, comfort, and sustained use. This thesis explores privacy-preserving and non-intrusive remote monitoring through two complementary studies. The first study presents an ambient Wi-Fi channel state information framework for recognizing agitation and eight daily activities. The proposed approach translates behavioral and physiological markers commonly captured by wearable sensors into the Wi-Fi sensing domain. The …

Constructing Female High School Students’ Stem Self-Efficacy: The Role Of High School Stem Research Experiences, Hyunjin Son

Dissertations

In the U.S., nearly a quarter of the workforce is employed in Science, Technology, Engineering, and Mathematics (STEM) occupations. However, the STEM workforce lacks diversity, limiting perspectives to address real-world problems facing society. While many factors influence decisions to pursue STEM majors in college and enter the STEM workforce, one factor commonly associated with performance and persistence in STEM is STEM self-efficacy. Independent research experiences have been shown to increase conceptual understanding and confidence in STEM, leading to STEM degrees and careers. As high school co-curricular STEM research opportunities become more common, the effects of such experiences on students’ STEM …

Secondary Biology Teachers’ Understandings Of Growth Mindset, Kathryn Chapman

Dissertations

This case study investigates how high school biology teachers understand and apply growth mindset principles in their daily instruction. Using surveys, semi‑structured interviews, and focus groups, the study examines how biology teachers interpret mindset, how they attempt to enact it, and how curriculum demands shape their efforts. Findings show that teachers’ beliefs about intelligence strongly influence their feedback, expectations, and instructional decisions. Teachers described biology as a subject in which struggle is highly visible, emotionally charged, and often tied to students’ prior knowledge, making mindset work both necessary and challenging. Results also indicate that students’ mindsets are shaped by broader …

Machine Learning For Predictive Energy And Emissions Modeling Of Vehicles And Power Grids In The United States, S M Tanvir Faysal Alam Chowdhoury

Dissertations

The environmental benefits of electric vehicle (EV) adoption depend on more than replacing internal combustion engine vehicles with electric powertrains. EV adoption reshapes electricity demand, interacts with regional generation mixes, and influences travel behavior and congestion, creating a coupled transportation-energy system in which vehicle and power-plant emissions must be evaluated together. This dissertation develops machine-learning frameworks for predicting energy consumption and emissions from vehicles and power grids under rising EV adoption. The first component forecasts grid emissions from EV charging. Using simulation data from NREL's Cambium database, a Prophet-based time-series framework predicts carbon dioxide, nitrous oxide, and methane emission rates …

Pseudo-Riesz Bases, Deborpita Biswas

All Dissertations

In this dissertation, we will introduce the concept of pseudo-Riesz bases, extending the influential notion of near-Riesz bases first proposed by J. Holub in the 1990s. Our goal is to develop an analogous theory for pseudo-Riesz bases, obtaining results parallel to those known for near-Riesz bases, with suitable modifications.

We will develop the foundational theory of pseudo-Riesz bases. Unlike classical Riesz bases, these sequences need not be complete or independent; however, they still retain meaningful expansion properties. We will investigate the conditions under which a Bessel sequence can be transformed into a Riesz basis through finite modifications. In particular, we …

Exploring Public Perceptions Of Genetic Risk In Substance Use Disorders, Brooke A. Goodenow

All Dissertations

This dissertation examines genetic risk perception, with specific emphasis on substance use disorders (SUDs), through a collection of three manuscripts. The dissertation examines genetic risk perception for hereditary diseases in existing literature, describes a methodological framework for capturing genetic risk perception across social media discourse, and identifies themes and emotional tone associated with genetic risk perception for SUDs across two major social media platforms (X and Reddit).

Combined, these three manuscripts expand and support previous findings about genetic risk perception and its role in shaping health beliefs and associated behaviors. The dissertation findings reveal numerous similarities in genetic risk perception …

Broadening Participation In Computing: Retention Pathways For Supporting Underrepresented Students, Oluwafemi Osho

All Dissertations

The computing sector's rapid growth has intensified demand for computing professionals, yet undergraduate computer science (CS) programs continue to lose substantial numbers of students, often within the first two years, before they reach degree completion. Attrition is not evenly distributed: women and other underrepresented minority (URM) students remain less likely to persist in CS despite broader increases in enrollment. These persistent disparities suggest the need to understand not only how to broaden entry into computing but also how students' experiences within programs shape retention over time. In this dissertation, I address this critical challenge by focusing on identifying inclusive strategies …

Three-Dimensional Gaussian Reconstruction Of Large-Scale Scenes Under Multi-View Geometry Constraints, Haohao Cui, Yanqiang Di, Qing Liu, Xianguo Meng

Journal of System Simulation

Abstract: To enhance the geometry reconstruction quality of the GS algorithm in large-scale scene reconstruction, an optimization method constrained by multi-view geometry reconstruction results was proposed. 2D Gaussian planes were used as geometric primitives to overcome depth anisotropy, and dense depth maps generated by DUSt3R and aligned by sparse point clouds were introduced as constraints. By designing a multi-stage optimization strategy that decouples geometry and rendering, the gradient conflict problem in multi-objective training was solved. Experiments on the MatrixCity dataset indicate that the method surpasses comparison methods in related indicators of geometry reconstruction quality and rendering quality in large-scale scenes. …

Interplay Of Atomicity, Polarization, And Quantization On Performance And Reliability In Gan Finfets, Salim I. Almenshad

Dissertations

GaN based nanoscale high-electron-mobility transistors (HEMTs) are the next generation of transistor technology that features the unique combination of higher power, wider bandwidth, low noise, higher efficiency, and temperature/radiation hardness than conventional AlGaAs and Si based technologies. However, enhancement mode operation for nanoscale channel region is the most recent needed area of research. As well as reliability of these devices remains a major concern. The main objective of this proposed research is to numerically investigate the role of atomistic inhomogeneity and quantization in low-dimensionality lateral tri-gated AlGaN/GaN FinFET devices. It is shown that 3-D configured AlGaN/GaN FinFETs with narrow enough …

Applications Of Machine Learning For Nondestructive Evaluation Data Analysis, Connor Chase Seavers

Dissertations

A fourth industrial revolution is currently taking place in the manufacturing sector, called “Industry 4.0,” where material production and fabrication processes are becoming fully automated using integrated sensors, closed-loop feedback mechanisms, and artificial intelligence/machine learning (AI/ML). The nondestructive evaluation (NDE) field has begun to follow suit by integrating AI/ML techniques in material inspection processes to automate defect detection for many NDE methods. Since material inspection processes are paramount in ensuring safety and reliability in critical manufactured products, it is important that new AI/ML techniques are trustworthy for NDE data analysis. The current approach to building trust in new AI/ML methods …

Global Kinetic Dynamics Of Black Hole Magnetospheres And Accretion, Martin Luepker

Arts & Sciences Graduate Student Theses and Dissertations

The Event Horizon Telescope (EHT) has provided stunning images of the immediate vicinity of two supermassive black holes, M87* and Sgr A*, revealing the plasma swirling around them. To understand the complex emission observed, researchers have turned to general relativistic magnetohydrodynamic (GRMHD) simulations, which model the plasma as a fluid. These simulations have been successful in reproducing some features of the EHT images, but they rely on assumptions that do not apply in the low-density, high-magnetic-field environments around these black holes. General relativistic particle-in-cell (GRPIC) simulations offer a first-principles approach to modeling this environment, but their application to global black …

Summaries Of Arkansas Cotton Research 2025, Fred M. Bourland

Arkansas Agricultural Experiment Station Research Series

Planted cotton acreage in Arkansas decreased in 2025 to 520,000 acres compared to 650,000 planted acres in 2024. Arkansas producers harvested 515,000 acres, which was a decrease of 125,000 acres from the 640,000 acres harvested in 2024 (https://www.nass.usda.gov/Quick_Stats/Ag_Overview/stateOverview.php?state=Arkansas&year=2025). The 515,000 harvested acres ranked Arkansas third nationally, trailing only Texas and Georgia in harvested acres (https://esmis.nal.usda.gov/sites/default/release-files/795725/cropan26.pdf). The average cotton yield, as reported by the USDA, was 1,239 lb lint/ac, which ranked fourth nationally, behind California, Louisiana, and Arizona. Arkansas farmers produced an estimated 1.329 million bales, which is a decrease from 1.788 million bales produced in 2024. This production still ranks …

A Quantitative Analysis Of Sea Turtle (Chelonia Mydas, Caretta Caretta, And Lepidochelys Kempii) Suture Morphology, Adolfo Emanuel Artigas Iv

Harriet L Wilkes Honors College Theses 2020 - Present

Sea turtle shells are formed of modified ribs, which, structurally, are sandwich composites. Sandwich structures provide both physical protection and pressure response associated with diving at depth. Carapacial sutures, tight joints between adjacent bones, connect modified ribs with collagenous fibers. Previous research on freshwater turtle shells suggests that sinuous sutures (highly convoluted) enhance compression strength. Limited research explored the form and functional significance of sutures in marine turtles. To investigate suture morphology and potential ontogenetic effects, I analyzed sutures in green (Chelonia mydas), Kemp’s ridley (Lepidochelys kempii), and loggerhead (Caretta caretta) sea turtles. Samples …

Disrupting The Demand For Commercial Sex To Combat Sex Trafficking And Destabilise Organised Crime Networks, Johan Van Graan

Dignity: A Journal of Analysis of Exploitation and Violence

Sex trafficking persists as a lucrative form of organised crime, sustained by ongoing demand for commercial sex. Using Rational Choice Theory, this article reframes sex buyers as active perpetrators and financial drivers of trafficking networks rather than peripheral actors. The article examines how buyers weigh risks and benefits when purchasing sex, especially in contexts with weak law enforcement. By analysing 53 active trafficking cases from 2021 and 36 prosecuted cases in South Africa (2007–2022), the research identifies clear patterns in buyer behaviour, network operations, and law‑enforcement responses. A central finding is the near-total absence of buyers in prosecutions, which reinforces …

Disrupting Transnational Human Trafficking Networks: A Practitioner's Perspective On Intelligence-Driven, Offender-Focused Strategies, Rochelle Keyhan

Dignity: A Journal of Analysis of Exploitation and Violence

This article examines human trafficking through the lens of organized crime and explores how this perspective can be applied to contemporary trafficking cases in the United States. While trafficking is often prosecuted as an isolated criminal act, many incidents are linked to larger transnational and domestic organized crime networks. The discussion highlights the activities of notorious syndicates, including international cartels, street gangs, and well-funded networks of sex buyers, demonstrating how these entities exploit vulnerable populations for profit. Reframing human trafficking as a sector within organized crime shifts investigative and prosecutorial strategies away from victim-dependent models, which often require survivors to …

Leveraging Technology To Measure The Strength Of Demand For Commercial And Trafficked Sex, Michael D. Shively, Bob Rodgers, Courtney Furlong, Brooke Ruffin

Dignity: A Journal of Analysis of Exploitation and Violence

The article examines Transaction Intercept (TI), an artificial‑intelligence platform designed to reduce sex trafficking by disrupting the revenue streams that draw organized crime into the market. Transaction Intercept deploys decoy online ads that appear to offer commercial sexual exploitation or prostitution. Automated "decoy" personas connect to individuals who click on these ads and engage them in text conversations. These exchanges can remain fully automated, ending with deterrence messages, or be transferred to police for potential enforcement action or to trained volunteers who attempt to discourage further attempts to buy sex. Transaction Intercept generates extensive, real‑time data on local demand for …

Balancing War And Peace In Taekwondo Athlete Development: A Multi-Criteria Coaching Decision Support Framework Using Leadership Scale For Sports And Fuzzy Ahp, King Harold A. Recto, Hazel Jade L. Antonio, Jhyrald Anthony P. Dalida

Electronics, Computer, and Communications Engineering Faculty Publications

Coaching effectiveness is frequently evaluated through competitive outcomes, with the assumption that coaching behaviors directly influence athlete performance. This study examined the relationship between perceived coaching behaviors and individual win percentage among collegiate Taekwondo athletes using the Leadership Scale for Sports (LSS). Descriptive statistics, correlation analysis, and regression analysis were conducted across five coaching dimensions: Training and Instruction, Democratic Behavior, Autocratic Behavior, Social Support, and Positive Feedback. Results showed that none of the coaching dimensions demonstrated a statistically significant relationship with win percentage. Although coaching behaviors did not significantly predict win percentage, the findings suggest that athlete development is shaped …

Optimizing Few-Shot Learning In Pruned Large Language Models With Task-Specific Prompts, Danyal Aftab

Dissertations

Few-shot learning enables large language models to efficiently perform tasks given only a limited number of labeled examples. However, training these models entirely from scratch requires substantial computational resources, making it challenging for many organizations to fully leverage their potential. This thesis explores how structured pruning, task-specific prompting, and parameter-efficient fine-tuning can be combined to preserve few-shot learning capabilities in compressed LLMs, while also extending their utility to real-world recommendation systems.

In this research, we propose the Tailored LLM framework, which first reduces model size through structured pruning and then enhances few-shot learning performance using carefully designed prompts. We experiment …

Spatial Structure And Energy Content Of Wakes Behind Single And Arrayed Undulated Cylinders, Taiga Naomi Drucker-Boisvert, OndˇRej FerˇCák, Jérémie Auzoux, Sarah E. Smith, Zein Sadek, Rowan Moore, Christain T. Murphy, Trevor Dunt, Jennifer A. Franck, Raul Bayoan Cal

Biologically inspired undulated cylinder geometries significantly influence wake structure and vortex-induced vibrations in turbulent flows, yet the underlying mechanisms are not fully understood. It is further unknown how these influences extend to multi-cylinder arrays, where interacting wakes accumulate and mix. This study examines the wake characteristics of an undulated cylinder and a smooth elliptic cylinder in single- and multi-cylinder array configurations, using particle image velocimetry and proper orthogonal decomposition (POD). Relative to the smooth elliptic cylinder, the undulated geometry induces pronounced spanwise-axial variability, characterized by enhanced near-wake mean momentum and weak far-wake signatures, consistent with reduced turbulent kinetic energy. While …

Pelagic Ecosystem Interactions Of An Offshore Longline Mussel Farm, Llucia Mascorda-Cabre, Philip Hosegood, Martin Attrill, Emma Sheehan

School of Biological and Marine Sciences

Long-term interactions of the UK's first large scale offshore mussel farm with the surrounding pelagic environment were studied to assess the farm's ecological impact. Pelagic fishes, zooplankton community and oceanographic parameters such as temperature, salinity, density, chlorophyll- α, dissolved oxygen and CDOM were quantified over seven years. Effects to oceanographic parameters were observed locally comparing samples collected on the east and west parts of the farm, evidencing turbulent mixing of the water column enhanced by the farm. There was no difference between zooplankton assemblage composition inside and outside the farm, only naturally occurring temporal changes were detected, supporting the hypothesis …
