Mechanical Characterization And Evaluation Of Additively Manufactured Titanium 5v-5mo-5al-3cr Alloy, Zachary Casias

Mechanical Engineering ETDs

Ti-5V-5Mo-5Al-3Cr (Ti-5553) is a near beta titanium alloy commonly used in aerospace applications. It is currently being explored for additive manufacturing (AM), but the fatigue behavior of this AM alloy needs to be well-understood for adoption in aerospace applications. The present work examines the tensile and fatigue behavior of LPBF manufactured Ti-5553. The effect of post-print heat treatments, effects of surface roughness, and print defects on the mechanical properties of AM Ti-5553 were also evaluated. Fatigue lives of as-LPBF and BAA material are nearly identical, and both are far below the fatigue lives of conventionally manufactured Ti-5553 of 350 MPa. …

Color On Canvas In Black Britain And Black Germany, Marisa J. Pickett

History ETDs

Using the artwork and poetry of Black artist-activists Lubaina Himid, Keith Piper, May Ayim, and Raja Lubinetzki, a connection was found between the increasingly anti-immigrant rhetoric of conservative politicians of the 1980s and the self-identification and belonging of non-white communities within the countries of Great Britain and Germany. By linking the produced artwork with the direct political initiatives of the time, we are able to draw parallels between the experiences of two diasporic communities, Black Britain and Black Germany, through artists and their work. Artwork can be seen as a medium through which to engage with the audience on a …

A Framework For Managing System Resources And Pricing In Multi-Provider Edge Computing Environments, Matthew Paul Salcido

Electrical and Computer Engineering ETDs

Multi-provider multi-user multi-access edge computing provides a recent market driven networking paradigm facilitating the user data offloading process. In this thesis, we introduce the AGORA framework, which employs a sophisticated multi-leader multi-follower Stackelberg game that jointly optimizes the data offloading, computing resource allocation, and computing resource pricing, all facilitated through a non-cooperative game-theoretic approach. In order to support the aforementioned modeling and approach, a novel utility function that quantifies the users satisfaction, factoring in the computing service cost, and an innovative profit function for the MEC providers is introduced, emphasizing the market penetration and the computing service provision costs. Numerical …

Mathematically Rigorous Deep Learning Paradigms For Data-Driven Scientific Modeling, Owen Nicholas Davis

Mathematics & Statistics ETDs

This dissertation explores the crucial role of data-driven modeling in science and engineering, with a focus on developing surrogate models to accelerate large-scale computational tasks, aiding in both outer-loop functions like uncertainty quantification and expensive inner-loop tasks within broader computational frameworks. Challenges arise with increased problem dimension and sparse, noisy training data, particularly significant when constructing surrogates for very expensive computational models where acquiring sufficient high-fidelity training data is unfeasible. In such scenarios, training surrogates from an ensemble of multifidelity information sources of varying accuracy and cost becomes essential. We emphasize neural network-based modeling paradigms, which are flexible in integrating …

The Effect Of Sodium Bicarbonate Supplementation In Markers Of Gut Permeability And Gastrointestinal Discomfort After Exercise In The Heat, Suzana Andrade De Oliveira

Health, Exercise, and Sports Sciences ETDs

Exercise performed under heat stress conditions is associated with an increase in gut permeability, commonly known as "leaky gut.". Recent studies suggest that sodium bicarbonate ingestion (NaHCO3) before exercise in the heat may offer ergogenic benefits. However, NaHCO3 is known to induce gastrointestinal discomfort (GI) and potentially exacerbate gut permeability. Therefore, this study investigated the effects of NaHCO3 on markers of gut permeability and gastrointestinal discomfort after prolonged physical exercise in a hot environment. To test this, we analyzed markers of intestinal permeability and injury pre and post exercise under heat stress comparing a NaHCO3 group to a placebo group. …

The Effects Of Acute And Chronic Ethanol Exposure On Mouse Spontaneous Spatial Behaviors, Tia Donaldson

Psychology ETDs

Within the open field, rodents spontaneously explore their surroundings by alternating between stops (absence of movement) and progressions (locomotion between locations). Few studies have examined how alcohol influences the organization of these spatial behaviors; therefore, we evaluated the effects of acute single-dose and binge-like alcohol exposure on spontaneous open-field behaviors. In Experiment 1, adults received a single injection of ethanol and explored a dark environment for 30 minutes. We found that mice assessed immediately after the injection exhibited reductions in locomotion and spontaneous behavior, while those tested 30 minutes later only exhibited suppressed locomotion. In Experiment 2, adolescent/adult mice received …

The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski

Biomedical Sciences ETDs

Mild traumatic brain injuries (mTBIs) often lead to acute symptoms like disorientation and discoordination, but the underlying mechanisms are unknown. Although most patients recover quickly from a single mTBI, repeated injuries can be debilitating. After an mTBI, a neurometabolic cascade produces metabolic burden and vulnerability. Spreading depolarizations (SDs) have been observed after mTBIs. Here we investigated SDs’ role in short-term motor behavioral deficits post-mTBI. We hypothesized that SDs contribute to the deficits, and exacerbated symptoms after repeated mTBIs. To test this, we used acute motor behavioral tests and long-term behavioral and cognitive tests after initiating SDs by mTBI, chemical, or …

Presidential Unilateralism In Contemporary U.S. Trade Policymaking: An Analysis Of The Section 232 Tariff Exclusion Process By The Trump Administration, Miao Wang

Political Science ETDs

On March 1, 2018, President Trump declared a 25% tariff on certain steel imports by invoking Section 232 of the 1962 Trade Expansion Act. Despite the extraordinary tariff measure, my research with logit regression and negative binomial regression analysis finds that the Trump Administration in its tariff exclusion process favored constituencies with a higher share of the president’s supporters and allowed import products from China more likely to receive the exclusions. I argue that the Trump Administration took these contradictory trade actions to achieve multiple goals at the same time: to pressure foreign trade partners and to protect vulnerable domestic …

Positioning Disability In Wilderness Space, Rebecca Hobart

Geography ETDs

This thesis examines the social construction of the disabled body in recreational wilderness space. A political ecology framework guides the research questions: What are the actual or perceived barriers to participation for differently abled hikers in wilderness recreational spaces, and how do these challenges manifest in long-distance hiking spaces? In situating Foucault’s theories of the body as shaped by power relations, this thesis asserts wilderness spaces to be privileged based on power conceptualized in normative notions of ability. 44 participants who self-identified as wilderness recreationalists with a disability and/or chronic health illness completed this study’s mixed-method questionnaire. Themes around practices, …

Logarithmic Similarity Measure Of Neutrosophic Z-Number Sets For Undergraduate Teaching Quality Evaluation, Wen-Ping Chen, Yi-Ming Fang, Wen-Hua Cui

Neutrosophic Sets and Systems

In practical decision-making problems, the different reliability levels of decision-makers in their evaluation information are usually ignored by most existing decision-making methods. Then, a neutrosophic Z-number (NZN) is a powerful model for simultaneously describing the restraint and associated reliability of evaluation information in view of truth, indeterminacy, and falsity Z-numbers. This paper first proposed a logarithmic similarity measure (LSM) of NZN sets, which is more flexible and can change its measure result by adjusting the exponential parameters of the restraint and reliability. Then, a multi-attribute decision-making approach is developed based on the presented LSM of NZN sets, and its applicability …
