Federated Neuromorphic Intelligence: Advancing Robustness, Efficiency, And Continual Adaptation In Edge Environments, Manh V. Nguyen

Dissertations

This dissertation investigates how spiking neural networks (SNNs) can improve federated edge intelligence by advancing three interconnected goals: communication efficiency, adversarial robustness, and continual adaptation. As edge computing deployments expand across Internet of Things (IoT), sensing, and privacy-sensitive applications, conventional federated learning approaches built around artificial neural networks (ANNs) face growing limitations in power consumption, bandwidth demand, and resilience to real-world uncertainty. SNNs offer an alternative computational paradigm based on event-driven, sparse, and temporally structured processing that is naturally suited to constrained edge environments. However, their behavior in practical federated settings remains insufficiently understood.

To address this gap, this dissertation …

Exploring The Spectrum Of Anxiety During Concussion Recovery: A Comprehensive Examination Of Symptom-Based Anxiety Disorders, Kori J. Durfee

Graduate Theses and Dissertations

Background: Anxiety is common following a concussion, arising from both psychosocial and physiological changes, and can manifest in diverse ways. Despite its complexity and association with worse outcomes, post-concussion anxiety is often assessed as a single construct. Characterizing anxiety presentations following injury may improve the identification of clinically meaningful symptoms and help inform future targeted interventions that can improve concussion outcomes. Purpose: The primary purpose was to determine if symptom-based anxiety disorders occur in adults with concussion and identify pre- and post-injury predictors associated with these disorders. Additionally, the clinical utility and predictive abilities of symptom-based anxiety disorders and variability …

Faster Than The Speed Of Bram: In-Memory Computing For Next Generation Fpgas On The Edge, Nathaniel Joseph Fredricks

Graduate Theses and Dissertations

Traditional computer systems are hitting the Memory Wall as machine learning applications are bottlenecked by the bandwidth between separate memory and compute units. Current FPGA architectures are able to bypass this bottleneck with block RAMs (BRAMs) that provide on-chip, in-fabric storage. However, their potential as the foundation of computing components is often overlooked; machine learning accelerators implemented on FPGAs face additional delays when transferring data between memory and compute units. These penalties arise from BRAM bandwidth limitations and movement of data through the reconfigurable fabric. To support FPGA-based accelerators on the edge and break the Memory Wall, reconfigurable architectures must …

Geospatial Analysis Of The Influence Of Wastewater Disposal On The Induced Seismicity In Oklahoma, Usa, Kristine Nagy

Quantifying The Short-Term Hydrogeologic Responses Of Highway Construction In Hot Springs, Arkansas, Billy Jack Summerford

Graduate Theses and Dissertations

In late 2020, excavation for the Highway 5 Bypass in Hot Springs, Arkansas exposed seepage faces along roadcut walls. Groundwater levels at nearby wells decreased by up to 20.9 ft and have remained ~20 ft below pre-construction values on average. This study quantifies changes in storage in the unconfined aquifer within the Hot Springs thermal recharge zone associated with the seepage faces using a numerical groundwater model calibrated to pre-construction head at well ARb4. Model scenarios are used to evaluate whether construction-induced seepage or drought best explains the decrease from late 2020 to early 2021. The numerical groundwater simulation represented …

Impacts Of Climate-Smart Agriculture On Greenhouse Gas Emissions In Southeast Arkansas Cotton, Cassandra Seuferling

Graduate Theses and Dissertations

Increasing concerns of climate change have led to the evaluation of greenhouse gas (GHG) emissions [i.e., carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)] from agroecosystems, particularly cotton (Gossypium hirsutum) production. Technology improvement and conservation agriculture methods [i.e., reduced-tillage (RT) instead of conventional tillage (CT) and the use of cover crops (CC)] require further evaluation regarding GHG emissions from Arkansas cotton production. The first objective of the study was to evaluate four gas-flux-determination methods [i.e., linear or exponential regression models, with negative fluxes (WNF) included in the dataset or replacing negative fluxes (RNF)] on CO2, CH4, and N2O fluxes …

Privacy Protection In Machine Learning: Methods For Structured And Unstructured Data, Karuna Bhaila

Graduate Theses and Dissertations

As machine learning models become increasingly integrated into data-driven decision-making, the protection of sensitive information throughout the model lifecycle is a paramount concern. As these models process and memorize sensitive, proprietary, or personal data, they risk leaking information through their outputs or internal states, especially in domains such as healthcare and finance. The protection of data in machine learning has thus been a crucial field of study. Within this paradigm, researchers have studied theoretical and application-oriented mechanisms for realizing privacy protections for various data formats. Nonetheless, privacy in machine learning still has many open problems, especially with the emergence of …

Developmental Assets And Risk-Related Restraint And Resistance Orientations Among Emerging Adult College Students: Examining Protective Associations, Summer N. Beck

Graduate Theses and Dissertations

Abstract Background: Although developmental assets are well established as protective factors during childhood and adolescence, less is known about their role during emerging adulthood, a period when the prevalence of several types of risk behaviors peak. For the U.S. college student, campus can provide ideal conditions for supporting the extended transition to adulthood. However, that same environment may increase exposure to health risk behaviors. This study examined associations between developmental assets and the risk-related restraint and resistance orientations involving sexual activity, alcohol, and illicit drugs among emerging adult college students. Methods: A cross-sectional correlational design was employed with a sample …

The Anti-‘Refugee Crisis’: A Comparative Analysis Of Anti-Immigrant Extremist Violence In The United States And The Nordic Countries, Ethan Mitchell

Graduate Theses and Dissertations

Using data from the U.S. Extremist Crime Database (ECDB), the Bias Homicide Database (BHDB), and the Right-Wing Terrorism and Violence (RTV) database, this study explores how attributes of anti-immigrant extremist violence compare across the United States and the Nordic countries. Compared to the long, complicated history of U.S. immigration and anti-immigrant violence, the homogeneity of the Nordic nations has only relatively recently been interrupted by mass immigration events like the mid-2010s’ “refugee crisis.” Rapid demographic change in these nations has inspired increased levels of extremism targeting immigrants and refugees. Quantitative analyses of cases ranging from 1990-2022 illuminate how broader social, …

Old-Growth Surveys And Landowner Outreach In The Cross Timbers Of Oklahoma, Jon Webb

Graduate Theses and Dissertations

The Cross Timbers ecoregion represents a critical ecologic transition zone, spanning approximately 17 million acres across Oklahoma, Texas, Kansas, and Arkansas. Situated between eastern deciduous forests and the southern Great Plains, the Cross Timbers are dominated by drought-tolerant post oak (Quercus stellata) and blackjack oak (Quercus marilandica). Despite retaining some of the most extensive old-growth forests in the eastern United States, this ecoregion remains threatened by urban expansion, agricultural conversion, altered fire regimes, and eastern red cedar (Juniperus virginiana) encroachment. This project sought to identify, survey, and document large, previously un-surveyed or unreported tracts of old-growth Cross Timbers in Oklahoma, …

Overwhelmed By Competing Priorities: Exploring Women’S Motivational Conflict Across The Menstrual Cycle, Arial S. Bloshinsky

Graduate Theses and Dissertations

This study examined whether the biological context of the menstrual cycle predicted overwhelming feelings due to competing bonding and achievement motivations (i.e., motivational conflict). Building on the motivational shift hypothesis, it was predicted that the luteal phase, characterized by elevated progesterone and heightened bonding motivation, would be associated with more overwhelming feelings from motivational conflict. To assess potential changes across the menstrual cycle, a within-person design was used where women reported their overwhelming feelings daily. Primary analyses did not support the hypothesis. Overwhelming feelings from motivational conflict did not differ across cycle phases. However, the expected mid-cycle peak in sexual …

Asynchronous Polymorphic Logic Locking, Kelby Haulmark

Graduate Theses and Dissertations

This work presents Asynchronous Polymorphic Logic Locking (APLL), a logic locking methodology that integrates polymorphic logic within the Multi-Threshold NULL Convention Logic (MTNCL) paradigm. APLL achieves Boolean satisfiability-attack resilience through a fault-based logic stripping approach followed by logic restoration, while leveraging the analog, dual-functionality of polymorphic gates to impede reverse engineering and removal attacks. In contrast to comparable SAT-resistant logic locking techniques, APLL provides inherent resistance to reverse engineering, reducing the viability of a broad class of attacks that rely on access to the locked netlist. A complete automated design flow is developed, enabling the transformation of combinational circuits into …

Groundwater Responses To Tidal Restoration At Pelican Marsh And Sea-Level Rise In Elkhorn Slough, California, Julie E. Nelson

Graduate Theses and Dissertations

Coastal wetlands represent a dynamic but vulnerable terrestrial-aquatic interface with future resilience controlled by historic hydrologic alterations, sea-level rise, and groundwater extraction. In diked coastal settings, poor tidal connectivity can degrade habitat from the impoundment of freshwater or hypersaline surface waters. Restoring tidal connectivity could foster marsh revitalization, but altering the surface hydrologic system could lead to unwanted salinity intrusion in shallow aquifers. Saline groundwater intrusion degrades freshwater quality and, while inevitable with sea-level rise, could be accelerated with tidal marsh restoration. To investigate this, I developed a steady-state groundwater flow model of Pelican Marsh, a diked, muted tidal marsh …

Sedimentary Provenance Of The Pliocene – Pleistocene Giant Foresets Formation, Offshore Taranaki Basin, Aotearoa New Zealand, Anurag Kulkarrni

Graduate Theses and Dissertations

Sediment input and dispersal in the Taranaki Basin, offshore New Zealand’s North Island, was influenced by a complex interplay of ocean currents and sea level fluctuations over the late Neogene. This period of time was recorded in the Pliocene-Pleistocene Giant Foresets Formation (GFF) that represents a rapid progradation of the western continental shelf into the basin. High sedimentation rates during this time were likely a major contributing factor to the emplacement of multiple, large-scale (up to ~3,500 km3) mass-transport deposits (MTD) that were caused by shelf and slope collapse within the GFF of similar scale to that of the well-studied …
