Sloshing Analysis Of An Isothermal Fluid In A Cylindrical Tank For Cryogenic Tank Design Using Smoothed Particle Hydrodynamics, Dillon Freeman

The Plymouth Student Scientist

This paper investigates the capability of Smoothed Particle Hydrodynamics to model the free surface sloshing response of an isothermal fluid in a cylindrical geometry. Eleven frequencies for two horizontal driving amplitudes (0.5 mm & 2.0 mm) were validated against experimental results and the influence of the starting direction of the tanks acceleration on the steady state response was investigated. The SPH results reproduced the overall behaviour of the experimental data closely over the range of frequencies tested, but produced higher amplitudes with greater variance in the region of the tanks natural frequency. Furthermore good symmetry was observed between sidewalls for …

An Exploratory Analysis Of Within And Between-Testlet Local Item Dependence In A Medical School Admission Situational Judgment Test Using Exploratory Structural Equation Modeling, Ester Sampson

Theses and Dissertations

To use a Cronbach's alpha coefficient or IRT methods on measuring instruments, both unidimensionality and local item dependence (LID) conditions need to be met. Moreover, LID can potentially introduce an unintended additional dimension into the test at the expense of the constructs of interest. Situational judgment tests use testlet structures, and thus likely present degrees of LID. We explored the latent structure and degrees of local item dependence in a situational judgment test (SJT) used by a Western United States medical school (WMS) for admission purposes. I used a fully deidentified data set from a group of 560 examinees who …

Quantifying Interpretation Reproducibility In Vision Transformer Models With Tavac., Yue Zhao, Dylan Agyemang, Yang Liu, J Matthew Mahoney, Sheng Li

Faculty Research 2024

Deep learning algorithms can extract meaningful diagnostic features from biomedical images, promising improved patient care in digital pathology. Vision Transformer (ViT) models capture long-range spatial relationships and offer robust prediction power and better interpretability for image classification tasks than convolutional neural network models. However, limited annotated biomedical imaging datasets can cause ViT models to overfit, leading to false predictions due to random noise. To address this, we introduce Training Attention and Validation Attention Consistency (TAVAC), a metric for evaluating ViT model overfitting and quantifying interpretation reproducibility. By comparing high-attention regions between training and testing, we tested TAVAC on four public …

Toward Effective Interfaith Relations Between Christianity And Indigenous African Religious Tradition In The Obolo Context In Nigeria – A Decolonial Theological Approach, Jerome Etenduk

Electronic Theses and Dissertations

This study focuses on the need for effective interfaith relations between Christianity and the Indigenous African Religious Tradition (IART) in a post-colonial Obolo context in Nigeria. It explores a history of complex religious crises in Obolo and identifies that Eurocentric/colonial theological imagination constitutes a significant reason for the problematic interfaith relations in Obolo. The dominant Eurocentric/colonial theology is founded on the theoretical framework that assumes that Europe (and America) is the hubris of knowledge. It negates and discounts the knowledge systems of other people. To know, they must learn from Europe and America. In this way, European missionaries to Obolo …

Increasing Awareness Of The Effectiveness Of Occupational Therapy In Cancer Rehabilitation, Aaliyah Parson, Zeida Gutierrez

Fall 2024 OTD Capstone Symposium

Many cancer survivors are faced with functional limitations when engaging in meaningful occupations due to side effects such as anxiety, pain, fatigue, weakness, nausea, etc. from receiving cancer treatments which can impact their quality of life. Occupational therapy has a significant role in supportive care for cancer survivors by providing occupation-based interventions that focus on maximizing function and mitigating functional decline. However, occupational therapy is underutilized in cancer care due to patients' lack of awareness of the role of OT and how it can improve quality of life after receiving cancer treatment. Therefore, this capstone project took place in Tallahassee, …

Relationship Of Emotional Intelligence To Workplace Stress And Burnout In Behavior Analysts, Elia Santos

Synthesis And Characterization Of Novel Diffusible Signal Factor Analogs For Antibiofilm Properties, Elisabeth Rachel Wiley

Electronic Theses and Dissertations Archive

Biofilms are composed of biomolecules, bacteria, and sometimes fungi and are considered the leading cause of antibiotic resistance. Biofilm formation and dispersion is regulated in part by signaling molecules called diffusible signal factors (DSF) through a process termed quorum sensing. However, the mechanism of action behind quorum sensing remains poorly understood. Chapter 1 focuses on the structure activity relationship (SAR) of DSF. DSF are medium chain fatty acids with an alkene at the C2-C3 carbon position. Tail length, branching, and cis/trans configuration all significantly affect antibiofilm action; these affects are also microbe specific. The chapter concludes with a discussion on …

The Illusory Coverage Doctrine Is Not A Doctrine At All (But It Should Be), Shannon W. Conway

Catholic University Law Review

The Illusory Coverage Doctrine, if it ever becomes a true legal doctrine, has the potential to be an incredibly useful tool in insurance law. But courts around the country take very different approaches to the doctrine, ranging from one end of the spectrum—a hard-nosed “pro-insurer” stance where coverage is not illusory so long as a policy provides any coverage—to the other—a muscular “pro-policyholder” public policy approach that requires coverage even if some other exclusion might have prevented coverage under the applicable policy. And along the spectrum are various other iterations, contributing to the complete lack of certainty or consistency about …

Defining The Chondrocyte “Mechanome”: How Mechanosensitive Ion Channels Trpv4 And Piezo1 Drive Changes In Gene Expression To Affect Cell Behavior And Cartilage Health, Daniel Raymond Palmer

McKelvey School of Engineering Graduate Student Theses & Dissertations

Chondrocytes, the only native cell population of cartilage, utilize mechanosensitive transmembrane ion channels to sense mechanical forces. Transient Receptor Potential Vanilloid 4 (TRPV4) is activated by physiologic levels of load (resulting in ~10% tissue deformation) while PIEZO1 is activated by supraphysiologic levels of load (resulting in >50% tissue deformation). TRPV4 activation promotes the expression of a limited number of chondrogenic genes and the production of vital cartilaginous matrix proteins, while PIEZO1 activation drives cell death and senescence, cytoskeletal weakening, and production of catabolic mediators, which contribute to the development of osteoarthritis (OA). However, the path connecting activation of these channels …
