Analysis Of Applied Modifications To A Cone Penetration Test-Based Lateral Spread Displacement Prediction Model, Alexander Edward Corob Dec 2019

Analysis Of Applied Modifications To A Cone Penetration Test-Based Lateral Spread Displacement Prediction Model, Alexander Edward Corob

Theses and Dissertations

This study set out to examine the effectiveness and reliability of six modifications to the Zhang et al. (2004) CPT-based lateral spread model. A regression analysis, distribution charts, and a discriminant analysis are performed to determine how effective the modifications are on the model. From the comparisons and statistical analysis performed in this study, application of these modifications reduces over-predictions from strain-based prediction methods. Unfortunately, the tendency to under-predict displacements on average is also increased.

Inferences On The Power-Law Process With Applications To Repairable Systems, Jularat Chumnaul Dec 2019

Inferences On The Power-Law Process With Applications To Repairable Systems, Jularat Chumnaul

Theses and Dissertations

System testing is very time-consuming and costly, especially for complex high-cost and high-reliability systems. For this reason, the number of failures needed for the developmental phase of system testing should be relatively small in general. To assess the reliability growth of a repairable system, the generalized confidence interval and the modified signed log-likelihood ratio test for the scale parameter of the power-law process are studied concerning incomplete failure data. Specifically, some recorded failure times in the early developmental phase of system testing cannot be observed; this circumstance is essential to establish a warranty period or determine a maintenance phase for …

Understanding The Effects Of Mass Mortality Events On Plant Communities And Consumer Behavior, Carolina Baruzzi Dec 2019

Understanding The Effects Of Mass Mortality Events On Plant Communities And Consumer Behavior, Carolina Baruzzi

Theses and Dissertations

Mass mortality events (MMEs) are die-offs that result in increased carrion biomass and sometimes the impairment of functional roles. Concurrently, several vulture species are declining. Carrion is a basal resource in ecosystems and its recycling by vultures is considered an ecosystem service. However, the consequences of simultaneously increasing carrion loads and declining vulture populations are unknown. I developed a theoretical framework predicting that, with increasing carrion biomass, carrion food web diversity would increase horizontally and vertically, respectively increasing and decreasing carrion recycling efficiency. Using a manipulative experiment, I investigated the role of bottom-up and top-down forces affecting plant communities during …

Characterization Of Fatty Acid Composition Of Bull Sperm With Varied Cryotolerance, Holly Evans Dec 2019

Characterization Of Fatty Acid Composition Of Bull Sperm With Varied Cryotolerance, Holly Evans

Theses and Dissertations

The objectives of this study were to determine fatty acid composition and acrosome status from bull sperm with different freezabilities (n = 12). We hypothesized that lipid fractions had differentiated fatty acid compositions and such differences influence sperm freezability and the sperm acrosome. Fatty acids were extracted from fresh frozen sperm and fractionated by solid-phase extraction. Thirtyour fatty acids were quantified. Saturated fatty acids were predominant, accounting for 71 to 80% of fatty acids in both fractions. Differences in composition between fractions existed (P < 0.001). Branched chain fatty acid concentrations (15 to 18 µg) were almost twice that of polyunsaturated fatty acid concentrations found in the polar fractions (8 to 9 µg; P < 0.001). Sperm with differentiated freezabilities had few differences in 22:0, 18:1 cis 9, and 14:0 13-methyl fatty acids (P ≤ 0.011). Analyses of acrosome status of sperm revealed that acrosomes were affected differently among bulls.


A Modular Open-Source Pre-Processing Tool For Finite Element Simulations Of Additive Manufacturing Processes, William Furr Dec 2019

A Modular Open-Source Pre-Processing Tool For Finite Element Simulations Of Additive Manufacturing Processes, William Furr

Theses and Dissertations

Additive manufacturing has shown the ability to produce highly complex geometries that are not easily manufactured through traditional means. However, the implications of building these complex geometries regarding thermal history requires more attention. AM process simulations have proven to be computationally expensive and require large amounts of pre-processing to execute. This thesis will start with a review of additive manufacturing along with current modeling efforts. Then, the development of a pre-processing tool for finite element simulations of these processes is presented. It is shown that the pre-processing tool significantly decreases the total time-to-simulation by removing manual steps. Finally, a study …

This study compares two experiential learning programs’ influence on the ethnocultural empathy development among college students at Mississippi College, a private, religious-affiliated university to explore how this empathy increases community service. 38 students were asked to complete the Scale of Ethnocultural Empathy (Wang et al. 2003) and were interviewed about their …


The Effects Of Impure Water Sources On The Early-Age Properties Of Calcium Sulfoaluminate Cements, Wendy Long Dec 2019

The Effects Of Impure Water Sources On The Early-Age Properties Of Calcium Sulfoaluminate Cements, Wendy Long

Theses and Dissertations

One of the benefits of calcium sulfoaluminate (CSA) cements is that these materials gain strength rapidly, where strength development is often measured in hours instead of days. This property makes these materials desirable for use in temporary, non-reinforced repairs of roadways, airfields, and navigable locks. The rapid repair of these infrastructure elements is critical to transporting supplies into regions devastated by disaster. In these austere environments, potable water may not be available in sufficient quantities to make vital repairs, and the use of impure water in the production of CSA cement-based concrete would be advantageous. However, the hydration products formed …
