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 …

Butting Heads With Respiratory Disease: Post-Epizootic Demography And Movement-Driven Spillover Risk In A Badland’S Bighorn Sheep (Ovis Canadensis) Meta-Population, Sean P. Ryder

Electronic Theses and Dissertations

Respiratory disease caused by Mycoplasma ovipneumoniae is among the most significant threats to bighorn sheep (Ovis canadensis) conservation in North America. In July 2021, contact between bighorn sheep rams and domestic sheep north of Badlands National Park (BADL), South Dakota, USA introduced M. ovipneumoniae into the Badlands bighorn sheep meta-population, triggering an epizootic that reduced the population by approximately 80%. I evaluated the post-outbreak status of this population through two complementary studies conducted from 2023 to 2025. In Chapter 1, I quantified disease prevalence, adult survival, lamb recruitment, and population growth rate (λ) using serial quantitative polymerase chain reaction (qPCR) …

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 …

Production, Characterization, And Diagnostic Application Of Monoclonal Antibodies Against The N-Protein Of Avian Metapneumovirus Subgroup B, Ravi Gupta

Electronic Theses and Dissertations

Avian metapneumovirus (aMPV) is a respiratory pathogen that causes Turkey Rhinotracheitis (TRT) in turkeys and Swollen Head Syndrome (SHS) in chickens. The infection leads to facial swelling, nasal discharge, reduced egg production, and poor growth. This virus is classified into four subgroups: aMPV-A, B, C, and D, with two other novel subgroups, in which aMPV-A, B, and C are most prevalent in the commercial flocks. In early 2024, aMPV-A and B outbreaks have been reported in the US, resulting in severe economic losses. An economic assessment estimates around $112 million in losses in Minnesota and up to $434 million in …

Bridging Language And Game Worlds: Semantic Representations And Text-Driven Terrain Generation For Procedural Content, Zhongyu Xie

Electronic Theses and Dissertations

Procedural Content Generation (PCG) systems produce vast quantities of game levels, terrain, and environments, but lack semantic interfaces: no shared vocabulary exists between natural language, designer intent, and the structured representations generators operate on. This thesis addresses the language-content grounding gap in PCG through two complementary studies spanning semantic analysis and semantic synthesis. The first study introduces a group-supervised contrastive learning framework for semantic representation of symbolic PCG maps under many-to-one semantics, where visually distinct maps may share the same design intent. The framework combines parameter-guided semantic grouping, LLM-based caption augmentation, and a multi-positive contrastive objective that aligns language with …

Evaluating Supplementation Strategies Using Precision Livestock Technologies And Energy Based Models In Developing Beef Heifers Grazing Dormant Rangeland, Kali-Jo Bentz

Electronic Theses and Dissertations

Replacement beef heifer development in extensive grazing systems is challenged by variation in forage quality, supplement intake, and animal behavior, all of which influence the ability to achieve targeted growth prior to breeding. Precision livestock technologies (PLT) enable continuous monitoring of individual animal performance, while energy-based nutritional models support individualized supplementation. However, their application under extensive grazing conditions remains poorly understood. Therefore, the objectives of this thesis were to (1) evaluate heifer utilization of multiple precision livestock technologies and their relationship with animal performance and (2) evaluate the accuracy of an individualized energy-based supplementation model by comparing predicted supplement allotments …

Detecting Poisoning Attacks In The Rag Systems Using Multi-Tier Anomaly Detection, Somtochukwu Orizu

Electronic Theses and Dissertations

Retrieval-Augmented Generation (RAG) systems aim to enhance the capabilities of language models by retrieving external knowledge during inference. However, the process of retrieving knowledge introduces new security vulnerabilities to these models, specifically through the possibility of retrieval poisoning attacks in which adversarial documents are added to the system knowledge base to poison the language model’s responses. Although there have been a variety of defenses proposed for retrieval poisoning attacks, limited work has been done in the area of anomaly detection in embedding spaces as a general defense against multiple retrieval poisoning attack strategies. This thesis investigates two embedding-space anomaly detection …

Demographic Impact And Diagnostic Evaluation Of Mycoplasma Ovipneumoniae In Bighorn Sheep Of The Pine Ridge Badlands, Jeffrey Tillery

Electronic Theses and Dissertations

Mycoplasma ovipneumoniae (M. ovi) decimates bighorn sheep (Ovis canadensis) populations through acute die-offs followed by years or decades of failed lamb recruitment. Test-and-remove management has emerged as the primary intervention to restore population growth, and this thesis quantifies the demographic costs of endemic M. ovi infection and evaluates the diagnostic tools upon which this strategy depends. I quantified vital rates across five bighorn sheep subherds (four infected, one uninfected) on the Pine Ridge Reservation (2023–2025), supplemented by pre-outbreak data (2017–2018) from the North Unit of Badlands National Park. Infected subherds declined (λ = 0.965, 95% CrI: 0.813–1.039) while the uninfected …

Securing Smart Agriculture With Communication-Efficient Federated Unlearning, Ujjwal Pudasaini

Electronic Theses and Dissertations

This thesis addresses the data poisoning attack in smart agricultural systems using federated unlearning, where the contribution of compromised field devices must be removed from the global model under communication constraints. We propose FedSCAN, a three-phase framework that identifies critical layers based on parameter sensitivity, classifies active neurons within these layers through relative weight change analysis, and performs unlearning via sparse low-rank adaptation to active neurons while freezing base model parameters. FedSCAN limits computational overhead to a compact parameter subset, enabling devices to participate in a communication-efficient manner. Experimental results on four datasets demonstrate that FedSCAN achieves up to 426.3× …

Ai-Assisted Wheat Spike And Spikelet Detection And Density Mapping Using Multiscale Remote Sensing Data To Support Wheat Grain Yield Forecasting, Hillson Ghimire

Electronic Theses and Dissertations

Wheat grain yield is determined by the number of spikes per unit area, the number of grains per spike, and kernel weight. However, spike number and spikelets per spike are still measured predominantly through manual counting, a labor-intensive and subjective process that limits phenotyping throughput and selection intensity in modern wheat breeding programs. This thesis develops and evaluates a deep learning framework for automated, high-throughput phenotyping of wheat spike and spikelet traits across complementary imaging scales and implements the framework as a deployable platform. First, two large-scale benchmark datasets with oriented bounding box (OBB) annotations were established, comprising 48,521 spike …

The research begins by developing queueing-based models to characterize EV charging demand under time-varying and stochastic arrival conditions. Time-varying Mt/M/1 and Mt/M/c …

Detecting And Characterizing Latent Subpopulations Of Classes Via Mixture Models, Andrew Simpson

Electronic Theses and Dissertations

A class of problems in statistical pattern recognition exists in which there is high-dimensional data with few realizations per class, commonly referred to as few-shot learning. Data that arises in forensic source identification, which deals with providing a probabilistic value of evidence with regard to the source of some object, falls into this class of problems. Namely, the data is sampled from a hierarchical sampling process, lives in a high-dimensional space, the number of sources (or classes) tends towards infinity, and there are few observations per source. This can be thought of as a few-shot learning problem. Because of these …

In Its Right Mind - Governance Of Social Superintelligence, David Filippi, Bill Tomlinson, Andrew W. Torrance

FIU Law Review

This Comment argues that a broad presumption of public access to court  documents is essential to preserving the legitimacy and constitutional values  of the American legal system. Although the principle of public access is  rooted in common law and constitutional tradition, individual states differ in  how they approach transparency in the context of court documents. These  jurisdictional inconsistencies continue to gain significance, as the digital age  has completely transformed the way people consume information. The  increasing digitization of court records has heightened the need for consistent  and constitutionally grounded standards that preserve transparency while  adequately protecting legitimate privacy interests. Florida’s …

Advancing Multi-Modal Learning, Swetha Sirnam

Graduate Studies Theses and Dissertations 2026

Multimodal learning aims to develop systems that understand and reason across multiple sources of information such as images, videos, audio, and text. These capabilities are central to applications including visual search, digital assistants, robotics, and visual question answering. Despite recent progress in multimodal large language models, current approaches struggle to capture the structured complexity of real-world visual data. Fine-grained visual details are often lost during multimodal alignment, models frequently fail to capture nuanced human intent, and existing methods remain limited in understanding long-form videos with complex temporal dynamics. Furthermore, many evaluation benchmarks rely heavily on explicit visual cues, which can …
