A Taxonomy-Driven Modular Defense Against Non-Canonical Language In Vision-Language-Action Models, Viraj Samson

Electronic Theses and Dissertations

Vision-Language-Action (VLA) models have recently achieved strong performance across manipulation benchmarks, but these benchmarks rely on highly templated instructions on which the models are typically fine-tuned, leaving their behavior under realistic language-side perturbation unclear. It remains an open question whether the linguistic flexibility inherited from vision-language pretraining survives this fine-tuning, or whether the resulting policies become narrowly tuned to benchmark phrasing and brittle to the intent-preserving language variation that real users naturally produce. We address this gap with a systematic study of VLA robustness under non-canonical instructions, comprising three components: a structured taxonomy of intent-preserving variations spanning linguistic, orthographic, and …

The Monstrosity Of “Deor”: Apophasis In Character And Form, Ada Smith

Electronic Theses and Dissertations

T. A. Shippey once referred to “Deor” as “that most perfect of Old English poems.” And indeed, the poem cannot help but inspire the reader to deep contemplation, even as it baffles scholars in so many ways. From its rare stanzaic structure to its anomalous refrain—“þæs ofer eode þisses swa mæg”—the elegy has inspired much debate within the scholarship. In fact, one of the few agreements among the scholars of “Deor” is the poem’s capacity to undermine all interpretations. The poem has the remarkable quality of mentioning many well-known legendary and historical figures while, at the same time, denying the …

Assessing The Impact Of Local–State Revenue Shares And Property Tax Structure On Effective Farmland Tax Rates: Panel Evidence From Seven Midwestern States, 2009–2022, Imtiaz Amin Chy

Electronic Theses and Dissertations

Property taxes are the primary revenue instrument of local governments in the United States, yet the burdens they impose are distributed unevenly. Farmland, because it cannot be relocated, often absorbs a disproportionate share. This paper examines two related questions: what fiscal factors determine how heavily agricultural land is taxed, and do those tax rates capitalize into farmland asset values? Using an annual panel of Iowa, Illinois, Indiana, Kansas, Minnesota, Nebraska, and Wisconsin from 2009 to 2022, we first document how each state allocates property tax revenue across four major spending categories (education, public welfare, health, and utilities) finding that all …

Computational Modeling Of Biophysical Transport: Respiratory Drug Delivery And Tissue-Level Physics, Md Tariqul Hossain

Electronic Theses and Dissertations

The nasopharynx, the upper part of the pharynx located at the back of the nose serves as a critical hotspot for initial respiratory infections via inhaled transmission, largely due to the presence of specific surface receptors that pathogens can exploit for cell invasion, combined with a relatively sparse local mucociliary substrate. To enhance the therapeutic efficacy against certain pathogens, such as the SARS and Influenza viruses, it is therefore essential to improve the targeted delivery of drugs to the nasopharynx. This study explores the use of intranasal sprays as a method for drug administration and models the transport of sprayed …

An Integrated Evaluation Of Trace Mineral Status, Regional Variation, And Supplementation Effects On Circulating Mineral And Reproductive Performance In American Plains Bison, Bailey M. Rodriguez

Electronic Theses and Dissertations

The continued expansion of the American Plains Bison (Bison bison) industry has increased the need for science-based nutritional recommendations tailored specifically to the species, due to limited species-specific research. Because trace minerals influence immune function, growth, and reproductive performance, establishing baseline mineral status and evaluating responses to supplementation are critical for advancing bison production and conservation efforts. This thesis integrates two complementary investigations to evaluate trace mineral status in American Plains bison at both regional and herd management levels. First, a herd level comparison evaluated the influence of differing mineral supplementation strategies on circulating mineral concentrations, herd performance, and reproductive …

Winter-Feeding High Forage Vs. High Concentrate Diets To Beef Cows: Effects On Placental Transcriptomics, Lactation Capacity, And Enteric Methane Emissions, Megan Ann Wehrbein

Electronic Theses and Dissertations

Nutritional management and lactation performance are critical factors influencing productivity in cattle. This research includes two complementary studies. The first study was a meta-analysis to develop a lactation curve for Bos taurus cattle in North America using data from machine or hand milked cows. Data from 7 studies were used resulting in 1340 cow-day observations. Milk yield was analyzed by parity (primiparous or multiparous) and feeding management (non-nutrient restricted or nutrient restricted), revealing that primiparous cattle peaked earlier and at lower yields than multiparous cattle, and nutrient restriction reduced peak milk yield. Overall, Bos taurus cattle followed lactation trends similar …

Evaluating Methodologies For Estimating Enteric Emissions And Modeling Greenfeed Technology Utilization In Extensive Beef And Bison Grazing Systems, Aletta Laura Husmann

Electronic Theses and Dissertations

Greenhouse gas (GHG) emissions from grazing ruminants represent a significant component of U.S. agricultural emissions. However, enteric methane (CH4) from cow– calf systems on extensive rangelands pose substantial measurement and management challenges. The Northern Great Plains (NGP) supports nearly one-quarter of the U.S. beef cow population, yet regionally representative, herd-level enteric emission data from commercial ranches remain limited. This thesis integrates empirical field measurements with modeling approaches to evaluate the feasibility of quantifying enteric emissions on extensive rangelands and to examine system-level drivers influencing data yield, costs, and operational performance. Enteric methane and carbon dioxide (CO2) emissions were measured from …

Aspergillus …

Page Evidence Promotion For Open-Domain Multimodal Document Question Answering, Abdolhossein Erfanshekooh

Electronic Theses and Dissertations

Open-domain multimodal document question answering requires retrieving a small set of answer-bearing pages from a large document collection before a vision-language model can generate an answer. Although modern retrieval systems may return hundreds or thousands of candidate pages, the answer model typically receives only the highest-ranked few. Consequently, relevant evidence may already be present in the candidate pool yet remain unavailable to the answer model because it is ranked below the reader cutoff. This thesis identifies this retrieval-to-reader gap as a page evidence promotion problem and proposes a framework for diagnosing and addressing it. First, page-level pseudo-supervision is derived from …

A Framework For Reliable Domain Ai: Knowledge-Grounded Data And Logic-Graph Reasoning, Yangxiao Bai

Electronic Theses and Dissertations

Large language models (LLMs) perform well on general tasks, yet their deployment in specialized, high-stakes domains such as public health remains unreliable. Models hallucinate facts, combine multi-step evidence incorrectly, and retrieve context that corrupts downstream reasoning. Three root causes underlie these failures: training data that underrepresents rare but critical domain themes, reasoning that is opaque and unverifiable, and evidence use that cannot be re-checked when the evidence changes. This dissertation addresses all three. First, we introduce HDBSCAN_SSA, a coarse-to-fine topic-modeling pipeline that couples density-based clustering with a novel Semantic Seed Aggregation algorithm. Using samples drawn from a larger corpus of …

Task-Aligned Knowledge Transfer For Vision-Language Models Across Diverse Visual Challenges, Dongyoun Kim

Electronic Theses and Dissertations

Pretrained vision–language models (VLMs) encode broad visual and semantic knowledge, but this knowledge does not always translate into reliable performance on specialized visual tasks. Multi-object region understanding requires fine-grained relational alignment, scientific document question answering requires structured reasoning over tables and charts, and robotic manipulation requires task-relevant perception to influence action generation. This dissertation studies these gaps as a problem of knowledge utilization: helping a pretrained model use available knowledge in a form aligned with the target task. Its central claim is that effective adaptation depends not only on model scale, data volume, or full-backbone fine-tuning, but also on three …

Strip-Till Adoption For Soybean Production In Eastern South Dakota: Plant Development, Seed Quality, And Economic Analysis, Nicolas Passone

Electronic Theses and Dissertations

Soybean production in eastern South Dakota faces a persistent challenge: cool, wet spring conditions combined with heavy soils limit the adoption of conservation tillage despite its soil health and environmental benefits. Strip-tillage has been proposed as a middle-ground practice capable of providing conservation benefits while maintaining the seedbed quality advantages of conventional tillage. However, its performance in soybean production in South Dakota had not been evaluated prior to this work. This research examined the effects of tillage systems and fertilizer placement-timing, fertilizer rate, and seeding rate on soybean plant development, nutrient uptake, seed yield, chemical composition, and partial net economic …

Imaging-Based Colorimetric Gas Sensing For Wearable Applications, Syed Saad Ahmed

Electronic Theses and Dissertations

Continuous monitoring of gases is a critical challenge for wearable health monitoring systems and portable environmental gas detection. The technology used for gas detection, including electrochemical sensors, metal oxide semiconductors, and non-dispersive infrared systems, is based on bulky optical components, which limit their practicality as an ideal tool for wearable and field-deployable stages. This thesis investigates if the passive colorimetric chemistry read-out provided by a low-power CMOS imager-based architecture can provide a non-invasive alternative across two different application domains: medical transcutaneous CO₂ monitoring systems and toxic gas detection from environmental. Two sensing platforms were developed and evaluated. In the first …

Towards Optimal And Resilient Ac/Dc Microgrids: Control Design, Analysis, And Implementation, Jun Zhang

Electronic Theses and Dissertations

Microgrids serve as a small-scale power grid for utilizing renewable energy to enhance energy reliability, sustainability, and resilience. As an autonomous system, an islanded microgrid can disconnect from the utility grid and operate independently by maintaining system voltage and frequency. However, this new feature introduces coordination problems among distributed generators (DGs), such as 1) how to make sure the voltage profile and current sharing in DC microgrid with different types of converters; 2) how to reduce the impact of cyberattack when the system coordination is performed based on communication, and 3) how to calculate the steady state under a droop …

Integration Of Ders Volt-Var Dynamic Constraint Into Time-Coupled Optimal Power Flow For System Stability, Shadrack T. Asiedu

Electronic Theses and Dissertations

The transition toward power systems with higher levels of inverter-based generation requires operating models that account for the dynamic support available from distribution-connected resources. Although inverter-based DERs can provide fast reactive-power support through functions such as Volt–VAR control, conventional optimal power flow models generally represent these resources as static power injections. In addition, transmission-level dispatch commonly represents the downstream distribution system as an aggregated load and does not explicitly consider the voltage at the point of common coupling. Consequently, an OPF solution may satisfy the transmission-bus voltage constraints while producing an operating point at which the downstream DERs do not …

Evaluating The Potential Of Genomic Selection For Grain Yield And Yield Component Traits In South Dakota Winter Wheat, Dante Koupal

Electronic Theses and Dissertations

Wheat (Triticum aestivum L.) is a major cereal crop worldwide, but recent gains in grain yield (GY) have not kept pace with projected demand. GY is a highly quantitative trait with low heritability that requires multi-year, multi-location phenotyping, limiting selection efficiency. Targeting higher heritability yield component traits, such as kernel size and weight, and incorporating them into the genomic selection (GS) pipeline has the potential to accelerate genetic gain for GY. The objectives of this study were to (i) understand the relationship between GY and the kernel-size traits, including thousand kernel weight (TKW), kernel length (KL), kernel width (KW), and …

The Spacetime Finite Element Method For Investigations Into Physics Ghost Systems And Time Parallel Preconditioning, Jax Wysong

Electronic Theses and Dissertations

This work operates on two fronts, focusing on interesting physical phenomena before turning our attention to an interesting numerical math problem. First, using the spacetime finite element method (FEM), we investigate a PDE system consisting of two Klein Gordon equations, which are coupled nonlinearly through the potential energy. The system contains a ghost (negative kinetic energy term). Systems such as these are generally deemed physically unstable, resulting in infinite energy in finite time. However, recent work has shown that this is not always the case. We investigate multiple scenarios arising from different initial conditions to characterize if/when a ghost system …
