A Risk-Informed Approach To Performing The Pre-Closure Safety Analysis For The Deep Borehole Disposal Of Radioactive Waste, Jennifer Elizabeth Leute

Nuclear Engineering ETDs

Deep borehole disposal is an emerging concept which involves disposing of radioactive

waste in boreholes several kilometers deep then backfilling to minimize radionuclide

transport and distribute weight. Unfortunately, little documentation exists on borehole

safety case development, especially for pre-closure operations. This study aims to close

this gap by proposing a graded approach matrix based on consequence, maturity, and

complexity. Two case studies are used to demonstrate this application: Hanford CsCl

capsules and spent PWR assemblies. Simulations are used to predict potential for dose

exposure, revealing CsCl capsules have a much higher potential for being above the 5

Vaginal cytology is a technique commonly used in dogs, cats, and rodents, and if proven effective in swine, it could serve as a practical tool for producers to confirm estrus status and improve reproductive management.

Travels In West Africa: A Critical Edition, Erere Iwhi

Student Works

First published in 1897, Mary Henrietta Kingsley’s Travels in West Africa became one of the most influential travel narratives of the Victorian era, changing the way British audiences encountered accounts of West Africa and its peoples. This critical edition examines the book not only as a travel narrative but also as a material artifact shaped by the historical, publishing, and cultural networks that guided its production, circulation, and reception. Extending its analysis beyond Kingsley's experiences of exploration, this edition investigates the forces behind the book’s creation, including Kingsley’s intellectual development, her identity as an independent female traveler and writer, and …

Parameter-Efficient Multimodal Adaptation: Ocr-Integrated Lora For Textvqa And Captioning, Karthik Ganesh Malini

Master's Theses

Vision-Language Models (VLMs) have emerged as transformative technologies for multimodal AI, yet they face significant hurdles in processing text-rich images required for enterprise applications like document understanding, medical imaging, and industrial inspection. Current VLMs struggle with accurate text extraction and reasoning, often exhibiting high hallucination rates and poor Optical Character Recognition (OCR) token utilization. To address these limitations, this research presents a comprehensive framework for optimizing parameter-efficient Low-Rank Adaptation (LoRA) fine-tuning strategies on state-of-the-art architectures, including LLaVA-1.5 and BLIVA-FlanT5. Our methodology integrates enhanced OCR token utilization, faithful caption generation, and specific hallucination mitigation techniques. We employ a multi-dimensional evaluation protocol …

Efficacy Of Oil And Gas Production Site Remediation In U.S. Arid/Semi-Arid Regions, Skye Ontiveros

Architecture and Planning ETDs

Oil and gas production (OGP) is expanding, paralleled by its polluting leaks and spills (LS), and outpaced by its waste. This raises the question: Does remediation of LS occur effectively when needed to protect the environment and public, particularly in major producing regions like arid/semi-arid regions (ASAR), which account for approximately 72% of US oil and 42% of gas production? To answer, a review of the eight largest national remedial laws, sourced from the Code of Federal Regulations (CFR), identified 14 OGP exemptions for remedial determinants (RDs): factors affecting remedial frequency and efficacy (e.g. LS monitoring and chemical disclosure). An …

Listen To The Birds: Sound Ecology At The Piano, Anna Showalter

Dissertations, 2020-current

This document explores the intersection between birdsong and piano music using four cases studies from the piano repertoire in the Western classical tradition. Using Jeff Titon’s framework of “sound ecology” as a lens, I ask whether the following pieces of music could in some way function as an “acoustic tissue among human and bird communities that becomes the basis for a healthy economy and a just community.” After exploring the history of birdsong in the piano literature as a microcosm of shifting attitudes toward birdsong in Western art music this study focuses on four pieces as case studies for analysis—Amy …

Corporeality In Choral Sound: Elements Of Consonant Diction Shaping Pre-Expressive Presence, Perceived Clarity, And Expression In English-Language Choral Music, Addison Walton

Dissertations, 2020-current

The genesis of this project stems from a lived experience performing with a professional choir, whose sung physical shaping of the English language—its crystalline clarity, profound expressivity, and the pre-expressive elements inherent in the delivery—was deeply and viscerally compelling. This overwhelming reaction was in response to their bodies; specifically, the sound their bodies produced that evoked a sense of corporeality, or tangible bodily presence. There was beauty to be found in the way their mouths physically formed the language, both within and removed from the semantic context.

This study sought to acknowledge those fleeting, pre-expressive moments in choral music and …

Dynamic Admittance Parameterization For Non-Prehensile Multi-Robot Transport With Optimal Coordinated Planning, Calvin J. Stahoviak

Computer Science ETDs

The Dynamic Admittance Parameterization of Non-Prehensile Multi-Robot Trans- port with Optimal Coordinated Planning (DYNAMO) architecture offers a practical framework for cooperative payload transportation using two robots equipped with nonholonomic mobile bases and four-degree-of-freedom manipulators. Coordinated mobile manipulation is a difficult problem in robotics, and the non-prehensile case is even more challenging than its prehensile counterpart because the robot bases and the payload are dynamically coupled. DYNAMO adapts arm motion in response to interaction forces and generates coordinated base trajectories that account for this coupling. Robust payload transport is achieved through the combination of opti- mal planning and adaptive compliant control, …

Irregularities In The Dynamics Of Large Networks: Cases On Social Networks And The Internet, Dheeman Saha, Abdullah Mueen, Shuang Luan, Afsah Anwar, Yangsun Hong

Computer Science ETDs

Dynamic networks capture evolving relationships among entities, and irregularities in their behavior often signal significant events. This dissertation investigates such irregularities across social and infrastructural networks. First, we analyze Twitter (prior to its rebranding to X) to characterize influencers, introducing a follower-overlap similarity measure that identifies micro-influencers beyond content-based methods.

We then examine election-related irregularities by comparing suspended and non-suspended accounts during the 2020 U.S. presidential election, revealing behavioral patterns linked to misinformation and coordinated manipulation.

Next, we develop an algorithm to infer post-specific diffusion networks, reconstructing who-saw-from-whom pathways for tweets at scale. This method uncovers structural differences in diffusion …

Diplomacy Derailed: Discrimination’S Detour On Route 40, Gage A. Kivlen

Masters Theses, 2020-current

The 1961 Route 40 campaign in Maryland became a critical battleground where three competing approaches to addressing racial segregation revealed deep contradictions in Cold War America. Route 40, a major highway between Washington D.C. and New York, became an international embarrassment when African diplomats from newly independent nations were repeatedly refused service at restaurants and hotels. This crisis prompted responses from three distinct actors: the Congress of Racial Equality (CORE), which employed grassroots organizing and direct action; the State Department's Special Protocol Service Section (SPSS), which pursued top-down diplomatic solutions; and the Federal Bureau of Investigation (FBI), which conducted extensive …

Recreating Fiber Recruitment With Fiber Recruitment Using Additive Manufacturing, Natalia D. Mciver

Biomedical Engineering ETDs

Injured ligaments are often repaired with tendon grafts which may over or under constrain the joint; there is a need for an artificial graft option with the mechanical properties of a native ligament. Crimped fibers within ligaments allow for recruitment which means the viscoelastic properties of stress relaxation and creep are not inversely related. A feasibility study using ACLs and large-scale crimp models to study viscoelasticity, led to an in-depth analysis of the scapholunate interosseous ligament. Using the Modified Kelvin spring-dashpot model, for describing viscoelasticity with a variable stiffness property (time dependent fiber recruitment), we defined the relationship between creep …

Space Vectors Discretization-Based Direct Torque Control Scheme For High Performance Induction Motor Drives, Francisco Balenga, Francis Mwasilu

Tanzania Journal of Engineering and Technology (TJET)

In this paper, a direct torque controller (DTC) based on discretization of space vectors (DSV-DTC) for induction motor drives is proposed. By using this technique, the number of voltage vectors is increased, consequently it reduces the torque ripple compared to the conventional DTC control scheme. Specifically, the switching table of the proposed DSV-DTC scheme is comprised of thirty-six nonzero voltage vectors compared to the six voltage vectors in the conventional DTC scheme. Furthermore, it makes use of a five – level torque hysteresis comparator instead of three-level of the conventional DTC. The performance of the proposed control scheme is validated …

Dynamic-Based Assessment Of Shear Connectors In Composite Bridges With Data Taken From The Surface Of The Deck Slab, Emmanuel S. Leo

Tanzania Journal of Engineering and Technology (TJET)

Most bridge management systems generally rely on visual inspections for condition assessment; this means that damage in inaccessible parts of the structure, such as shear connectors in concrete composite bridges, can remain undetected until failure occurs. Localised non-destructive techniques are limited to small areas, time-consuming, and require prior knowledge of the damaged zone. These limitations can be overcome by using dynamic-based techniques. This study aims to investigate experimentally the efficiency of dynamic-based techniques in assessing the condition of shear connectors based on measurements taken from the surface of the deck slab. The study involved the construction of five composite beam …
