A Parallelized Multi-Component Radiation Testing Methodology For Systems-On-Chip, Weston M. Smith

Theses and Dissertations

As the space industry expands, there is an increased reliance on system on chip (SoC) devices in high radiation environments. The reliability of these devices becomes crucial, especially in space applications. The industry's rapid growth has led to a massive expansion in the use of Commercial Off-The-Shelf (COTS) components. Electronic systems are vulnerable to single event upsets (SEUs) and the failure modes caused by SEUs are not fully understood, especially for COTS SoCs. Standard radiation testing techniques of SEUs use a single core of a multi-core processor to monitor bit flips. In this work, we present a parallelized radiation testing …

Examining The Effects Of A Complexity-Based Treatment For One Child With Down Syndrome Using Single-Case Design, Markelle Luddington

Theses and Dissertations

Common language difficulties observed in English-speaking children with Down syndrome (DS) and developmental language disorder (DLD) include challenges with marking tense and agreement on verbs, particularly with BE verbs. In addition, difficulties with syntactic movement may further exacerbate these challenges, often resulting in increased omission errors. A complexity-based approach to treatment target selection has been suggested as one method to address these needs. Therefore, this single-case design study examined the effects of a complexity-based treatment approach for one participant with Down syndrome. Specifically, this study investigated the effects of targeting a more complex treated structure, auxiliary BE questions, and the …

Sequencing Of Chenopodium A-Genome Diploids To Identify Potential Mechanisms Of Speciation: A Preliminary Study, Riley Roser

Theses and Dissertations

The genus Chenopodium is of increasing significance, mainly due to allotetraploid quinoa (C. quinoa Willd.,2x = 4x =36, AABB genome) becoming globally recognized for its high nutritional value and tolerance for stress. Diploid A-genome relatives of quinoa in the Western Hemisphere have shown speciation patterns congruent to adaptive radiation, particularly in the North American continent, where a number inhabit ecological niches while others form mixed populations where they are sympatric. Characterization of the genetic mechanism(s) underlying this rapid speciation, could clarify their potential usefulness for improving quinoa . Previous whole-genome assemblies of AA diploids C. watsonii A. Watson and C. …

Context-Sensitive Control-Flow Analysis For Non-Standard Language Semantics, Tim Whiting

Theses and Dissertations

Control-Flow Analysis (CFA) is a static technique for understanding the execution of higher-order programs without running the code. CFA aids in identifying bugs, assisting program comprehension, and exposing optimization opportunities. Constructing a CFA typically begins with an idealized evaluator--such as an abstract machine or interpreter--and proceeds by approximating components of evaluation to ensure that: (a) the analysis is sound (representing all possible behaviors), and (b) the analysis is guaranteed to terminate (finitely representable). These constraints necessitate a loss of precision, providing an approximation of the values that flow to program locations rather than exact execution traces. This imprecision causes the …

Development Of A Low-Cost Roadside Monitoring System For Identifying High-Emitting Heavy-Duty Trucks, Spencer Larson

Theses and Dissertations

This project investigated the feasibility of using low-cost sensors to identify high-emitting heavy-duty diesel trucks through roadside emissions monitoring. A sampling system was designed and tested in both laboratory and field environments to evaluate sensor performance and measurement reliability. In the laboratory, controlled engine testing enabled direct comparison between low-cost sensors and research-grade instruments to establish baseline accuracy, response time, and sources of uncertainty. These tests demonstrated that while low-cost sensors exhibit greater bias and slower response, several are capable of detecting transient emission events. Field deployments revealed that real-world conditions, such as plume dilution, spatial variability, and short exposure …

Wounded Domestic Ecologies: Ecofeminist Readings Of Gendered Trauma In Purple Hibiscus, Erere Victory Iwhi

Theses and Dissertations

This thesis examines Chimamanda Ngozi Adichie's Purple Hibiscus through an ecofeminist and postcolonial ecocritical lens, developing the concept of "wounded domestic ecology" to analyze how gendered violence operates within domestic space. Drawing on trauma studies, particularly J. R. Kurtz and Rob Nixon's concept of slow violence, it argues that harm in the novel is accumulative, produced through repetition, surveillance, ritual, and spatial regulation. Eugene's household functions as an environment that disciplines bodies, governs language, and embeds fear into everyday life. In contrast, Aunt Ifeoma's home in Nsukka offers a counter-ecology structured by sound, shared labor, and dialogic authority, interrupting the …

This study investigated whether species-level gut microbiome composition is associated with body mass index (BMI) in the AWI-Gen 2 cohort, and whether BMI-associated microbial signals remain detectable after accounting for the dominant geographic structure of the microbiome. Gut microbiome community structure and diversity were characterized across 1,665 participants, and differential abundance analysis was used to identify taxa associated with BMI after controlling for study site. Machine learning models were then trained to assess how …

Modeling The Spread Of Competing Narratives In Multimodal Social Media Network, Mayor Inna Gurung

Theses and Dissertations

Social media has fundamentally transformed how narratives are produced, contested, and disseminated, enabling competing interpretations of the same event to spread rapidly across networked populations. Understanding how narratives gain traction over others in these environments is critical for addressing misinformation, supporting informed public discourse, and designing effective counter-messaging strategies. Yet existing research largely treats narrative propagation as a single-process phenomenon and focuses predominantly on textual data, overlooking both the competitive dynamics between opposing narratives and the growing role of visual symbolic communication in shaping how narratives are received. This dissertation addresses these gaps through a multi-platform, multimodal framework applied to …

Spatiospectral Lobes And Radiation Modeling Of Partially Coherent Supersonic Jet Noise, Tyce Wayne Olaveson

Theses and Dissertations

Noise fields generated by high-performance military jets are known to contain acoustic structures that differ from their simulated and lab-scale counterparts. These differences may limit current noise control efforts, which are designed and tested at scale before being considered for full-scale aircraft. One such noise structure is the presence of spatiospectral lobes, which appear as multiple spectral peaks at single microphone locations and multiple radiation lobes in field reconstructions. This dissertation uses data collected from the T-7A jet noise measurement to characterize the spatial behavior of the spatiospectral lobes as well as their first time-domain description. A multiple wavepacket decomposition …

The Relationship Between Musical Ability And Perceptual Skills For Speech Motor Learning In Young Adults, Emily Catmull

Theses and Dissertations

Speech motor learning is the multimodal process of acquiring speech sounds. Speech motor learning is trained through speech-language pathologist intervention in individuals across the lifespan. Previous research has explored which factors can influence speech motor learning, such as musical experience or training, which is the subject of this study. Sixty young adult participants (four male, 56 female) were recruited as part of a larger study that examined four possibly influential factors: bilingualism, phonetic knowledge, perceptual skills, and musical experience. Since the adult population has already acquired all the speech sounds in English, learning was measured using nonnative consonant clusters. Participants …

From Theory To Practice: Investigating Process Safety Skills Acquisition And Bridging The Industry Readiness Gap, Brittany Butler-Morton

Theses and Dissertations

Process safety management is vital to companies operating highly hazardous materials or processes, and it is of interest to the engineering community as poor process safety judgments can have catastrophic results. Process safety judgments consider more than the prioritization of safety, as they are often influenced by elements like production, spending, reputation, and time. As such, it’s important to prepare engineering students nearing graduation for the complexity of these judgments and narrow the Theory-to-Practice gap for students entering industry. This work sought to identify 1) how the Theory-to-Practice gap is manifesting in process safety judgments, and 2) how the application …
