Wind Hazard Resilient Construction Mitigation Decision-Making Using A Multi-Objective Optimization, Erin Gregory

Masters Theses & Specialist Projects

While storms worsen and damage to homes increases, limited information is available about mitigations that are effective in lessening damage to homes and/or buildings. Information on past storms exists within FEMA’s Hazus-MH application, but the information provided by the data within the Hazus-MH application, while very informative on its own, was decidedly more precise and useful when optimized to provide defined information to those responsible for determining building codes or regulations for homes.

The research available from Hazus-MH details results from past storms categorized by building type, mitigations, and intensity of disaster. The data can be used to simulate storm …

A Monte Carlo Analysis Of Ordinary Least Squares Versus Equal Weights, James Brewer Ayres

Masters Theses & Specialist Projects

Equal weights are an alternative weighting procedure to the optimal weights offered by ordinary least squares regression analysis. Also called units weights, equal weights are formed by standardizing scores on the predictor variables and averaging these standardized scores to create a composite score. Research is limited regarding the conditions under which equal weights result in cross-validated 𝑅𝑅2 values that meet or exceed optimal weights. In this study, I explored the effect of various predictor-criterion correlations, predictor intercorrelations, and sample sizes to determine the relative performance of equal and optimal weighting schemes upon cross-validation. Results indicated that optimally weighted predictors explained …

The issue of vertical clearances along highway systems impact the functionality of the road network. Extracting current routing clearances for each structure can be a challenging and hazardous task. Pavement changes and roadway rehabilitation projects can alter roadway geometry, complicating efforts to maintain accurate clearance databases. Vertical clearance measurements may vary from one lane to another beneath overhead structures and are often difficult to obtain due to high traffic volumes. Inherently, traditional methods that are used to obtain the measurements routinely impede the flow of traffic and subject workers to dangerous environments. This study will examine the use of a …

Some Generalizations Of Classical Integer Sequences Arising In Combinatorial Representation Theory, Sasha Verona Malone

Masters Theses & Specialist Projects

There exists a natural correspondence between the bases for a given finite-dimensional representation of a complex semisimple Lie algebra and a certain collection of finite edge-colored ranked posets, laid out by Donnelly, et al. in, for instance, [Don03]. In this correspondence, the Serre relations on the Chevalley generators of the given Lie algebra are realized as conditions on coefficients assigned to poset edges. These conditions are the so-called diamond, crossing, and structure relations (hereinafter DCS relations.) New representation constructions of Lie algebras may thus be obtained by utilizing edge-colored ranked posets. Of particular combinatorial interest are those representations whose corresponding …

The Effects Of Aging On Attention In Associative Learning, Katie Wheeler

Masters Theses & Specialist Projects

In this study we investigated how aging affects attention to predictive and uncertain cues during associative learning. According to Mackintosh’s theory of predictiveness (1975), attention will be allocated to cues that most reliably predict an outcome. An opposing theory of uncertainty from Pearce and Hall (1980) suggest attention will be allocated to cues whose outcomes are uncertain. Although these theories are contradictory, both are well supported in the associative learning literature. There is evidence that young and older adults give more attention to cues that are predictive compared to nonpredictive cues (Mutter et al., 2019), and that young adults respond …

Application Of Excitation-Emission Matrices To Fluorescent Dye Tracing Of Groundwater Flow, Cayla M. Baughn

Masters Theses & Specialist Projects

Fluorescent dye tracing of groundwater is a technique employed particularly in carbonate rock karst regions to examine karst hydrology by mapping underground flow paths. It is important to understand the hydrology of karst environments because solutionally-enlarged conduits may allow the rapid influx of contaminants into the groundwater system. Fluorescent dye tracing involves the injection of a fluorescent dye into an appropriate injection site (sinking streams, sinkholes, or even through soil flushed with water) and is followed by sampling at sites where the dye may be recovered (typically springs). Various methods exist by which sampling may occur, but all methods ultimately …

Solvent-Free Synthesis Of Metal Coordination Compounds Using Ball Mills, Jenna Cantway

Masters Theses & Specialist Projects

Mechanochemistry utilizes mechanical energy to promote chemical reactions to completion. Samples ground with a ball mill are placed under consistent pressure and temperature, which allows for increased surface area, shorter reaction times and overall better control of reaction conditions compared to the use of a mortar and pestle. Many synthetic techniques to prepare metal coordination compounds use a solvent. The solvent promotes the reactions by providing a route for reagents to interact. While solvents facilitate reactions, there is interest in reducing or eliminating solvents altogether during the synthesis process due to potential instability of a solvent under certain experimental conditions …

Synthesis Of Cds/Zns Core/Shell Semiconductor Nanoparticles, Austin Skyler Antle

Masters Theses & Specialist Projects

Core/shell semiconductor nanoparticles are of great interest as photocatalysts due to their large surface area per volume and tunable band gaps. The synthesis of core/shell semiconductor nanoparticles has traditionally involved the use of binding ligands to ensure the particles do not aggregate. These binding ligands lower the surface area of the nanoparticles though, reducing their overall efficiency. Ionic liquids have been found to be capable of acting as both solvents and stabilizing agents for synthesis of catalysts with highly active surfaces. Our experiments focus on the synthesis of CdS/ZnS core/shell nanoparticles with the ionic liquid 1-butyl-3-methylimidazolium methyl sulfate, [BMIM][MeSO4], acting …

Book Genre Classification By Its Cover Using A Multi-View Learning Approach, Chandra Shakhar Kundu

Masters Theses & Specialist Projects

An interesting topic in the visual analysis is to determine the genre of a book by its cover. The book cover is the very first communication to the reader which shapes the reader’s expectation about the type of the book. Each book cover is carefully designed by the cover designers and typographers to convey the visual representation of its content. In this study, we explore several different deep learning approaches for predicting the genre from the cover image alone, such as MobileNet V1, MobileNet V2, ResNet50, Inception V2. Moreover, we add an extra modality by extracting text from the cover …

Validation Of A Novel Vo2max Protocol, Griffin Green

Masters Theses & Specialist Projects

Though there are several to choose from, the Bruce protocol is the most commonly utilized treadmill protocol when assessing maximal oxygen consumption (VO2max). Originally developed for cardiac patients, the Bruce protocol may not be an appropriate treadmill protocol for young or trained individuals with higher levels of cardiorespiratory fitness. The steep grade used often leads localized muscular fatigue, which may cause participants to end the test prior to reaching their true VO2max. Another popular protocol, the Astrand, also utilizes a steep grade, but the speed remains constant. Similar to the Bruce, the Astrand protocol may not prompt a maximal cardiovascular …

Effects Of Alpha- And Beta-Adrenergic Receptor Blockade Upon Inflammatory Responses To Acute And Chronic Sleep Fragmentation, Nicholas David Wheeler

Masters Theses & Specialist Projects

Generally, sleep is viewed as a recuperative process and its dysregulation has

cognitive, metabolic, immunological, and inflammatory implications that are largely deleterious to human health. Epidemiological and empirical studies have suggested that sleep fragmentation (SF) as result of obstructive sleep apnea (OSA) and other sleep abnormalities leads to pronounced systemic inflammatory responses, which are influenced by the sympathetic nervous system (SNS). However, the underlying molecular mechanisms contributing to SNS regulation of SF-induced inflammatory states are not fully understood. To assess the effects of the SNS system, C57BL/6j female mice were placed in automated SF chambers (12L:12D) and subjected to either …

An Application Of The Interpersonal Psychological Theory Of Suicide In College-Age Survivors Of Sexual Assault, Ava Katherine Fergerson

Masters Theses & Specialist Projects

Sexual victimization is a pervasive public health concern that disproportionately affects college students and results in severe mental and physical health risks for survivors. Despite low prevalence rates in the general population, a national study found that 33% of survivors of rape reported suicidal ideation, and 13% actually made a suicide attempt (Kilpatrick et al., 1992). Although it is clear that survivors of sexual violence are at increased risk for suicide, knowledge is largely limited to epidemiological studies. Few studies have integrated theories of suicide to understand how and why this population is at such elevated risk for suicidal thoughts …
