Topology Optimization Of Internal Cooling Channels In Turbulent Flows, Shinjan Ghosh

Electronic Theses and Dissertations, 2020-2023

Topology optimization, introduced by Bendsoe and Sigmund in 1988 has been a topic of research in the structural mechanics field for several decades. This technique is commonly used to optimize system performance of structural components with minimum material usage by varying the distribution of materials in a given domain. Fluid dynamic topology optimization, a relatively new research topic uses a method of adding or subtracting materials to a given flow domain to obtain an optimal flow-path for a given objective function. While the structural TO creates a solid structure by introducing holes into the domain, fluid TO introduces solid into …

Using Expectation Violation Theory To Evaluate Dialectal Bias In Courtroom Contexts, Christina Joseph

Electronic Theses and Dissertations, 2020-2023

There is much evidence to indicate the role of speaker accent expectations and its impacts on the subsequent rating of the speaker. Additionally, examples including the Central Park Five as well as Rachel Jeantel of the Trayvon Martin case indicate the impacts of this speaker rating particularly in the context of the courtroom. This necessitates the further evaluation of the impact of dialectal bias on speaker ratings especially in the context of a courtroom due to the severity of the impacts. Utilizing a 4x2 between subjects experimental design manipulating on the basis of both dialect and speaker expectation, this study …

Acoustoelectric Amplification In Piezoelectric-Silicon Micromachined Lamb Wave Devices, Hakhamanesh Mansoorzare

Electronic Theses and Dissertations, 2020-2023

In this dissertation, heterostructured micro-acoustic devices are explored that leverage the interactions between acoustic phonons and electrons to enable radio frequency (RF) signal amplification or attenuation. Thin films of piezoelectric and semiconductor material are tailored into a heterostructure that allows for a strong acoustoelectric (AE) effect due to the combination of high electromechanical coupling and high electron drift velocity in said films respectively. In such devices, the relative electron drift and acoustic velocities could determine whether the RF signal undergoes AE gain or loss, rendering the device non-reciprocal. This is a highly sought-after property for building isolators and circulators which …

A Mixed-Methods, Grounded Theory Study Of Online Meaning-Making During The Pandemic, Kaitlyn Montcrieff

Electronic Theses and Dissertations, 2020-2023

To be human is to seek to understand the known and unknown world. The Covid-19 pandemic offers researchers the opportunity to examine online meaning-making on a more ubiquitous magnitude than ever experienced in history, without positioning the digital world as less authentic, or distinct, from the physical. Using mixed-methods grounded theory, this study posed the research question: (RQ) How do high school parents use an online community to (re)conceptualize aspects of contemporary society? The NRC Emotion Intensity lexicon (Mohammed, 2018) was used to score online forum posts from 2018-2021 using eight emotions to quantitatively represent changes over time. The qualitative …

Data Driven Methods For Large Scale Network Level Traffic Modeling, Rezaur Rahman

Electronic Theses and Dissertations, 2020-2023

Rapid growth in population along with urban-centric activities impose a massive demand on existing transportation systems, thus increasing traffic congestion and other mobility related challenges. To overcome such challenges, we need network-scale models to accurately predict real-time traffic demand and associated congestion. However, traditional network modeling approaches have shortcomings due to the complexity in traffic flow modeling, limited scope to incorporate real-time data available from emerging data sources and requiring excessive computation time to generate accurate estimation of traffic flows. Advancement in traffic sensing technologies with big data has created a new opportunity to overcome these challenges and implement deployable …

An Examination Of Precollegiate Education Programs In The K-12 Context: The Role Of Student Motivation And Perception And Recruitment And Retention Strategies For Successful Outcomes, Daniel Santos

Electronic Theses and Dissertations, 2020-2023

State leaders have responded to recruiting and retaining teachers in the workforce with Grow Your Own (GYO) programs for recruiting secondary students or community members into education. An example of a GYO is the precollegiate Teacher Academy (TA) program offered in local high schools as a career and technical education pathway. The TA provides guidance for high school students thinking about the teaching profession. TA educators foster students' interest and recruit and retain them in education by exploring their motivations. This study was a triangulated mixed methods study with the quantitative/qualitative model of utilizing both data sets to determine student …

Bringing Instagram Posts Into Being: A Study Of Fyc Students' Self-Sponsored Posting Practices And Transfer Opportunities, Jessica Kester

Electronic Theses and Dissertations, 2020-2023

Social media platforms have offered students—and all of us—more opportunities for self-sponsored writing. In response to calls from researchers to explore students' 21st-century writing practices and their relevance to college writing instruction, this dissertation articulated and applied a feminist teacher research methodology and a mixed-methods research design to explore first-year composition (FYC) students' self-sponsored writing practices, attitudes, and transfer opportunities on a popular, albeit under-examined, social media application: Instagram. This study found that students have developed elaborate, rhetorical, multimodal composing processes that include planning, drafting, evaluating, selecting, and styling images as well as planning, drafting/revising, and styling captions. Additionally, though …

Using Peptide Design To Engineer Polyelectrolyte Complex Biomaterials, Sara Tabandeh

Electronic Theses and Dissertations, 2020-2023

The self-assembly of oppositely charged polymers provides a versatile platform to design materials for diverse applications in biology and medicine. Electrostatically-driven phase separation of oppositely charged polymers in aqueous solution gives rise to the formation of a polymer-rich phase called a polyelectrolyte complex (PEC). PECs can be in the form of liquid droplets (complex coacervates) or amorphous solid precipitates. Unlike synthetic polymers, peptides are good candidates for developing tailor-made formulations and structure-property relationships due to their biocompatibility, precise control over sequences, and ability to program hydrogen bonding interactions. However, little is known about the effect of combining additional molecular interactions …

Leveraging Multimodal Learning Analytics To Understand How Humans Learn With Emerging Technologies, Elizabeth Cloude

Electronic Theses and Dissertations, 2020-2023

Major education and training challenges are plaguing the United States in preparing the next generation of the future workforce to meet the demands of the 21st Century. Several calls have been released to improve education programs to ensure learners are acquiring 21st century knowledge, skills, and abilities (KSAs). As we embark on the digital and automation ages of the 21st century, it is essential that we move away from traditional education programs that define and measure KSAs as static constructs (e.g., standardized assessments) with little consideration of the actual real-time deployment of these processes, missing critical information on the degree …

Canvas Course Design And The Effects On Faculty Workload And Stress During Covid-19, Christine Kugelmann

Electronic Theses and Dissertations, 2020-2023

COVID-19 forced all education online during Spring 2020 requiring face-to-face higher education faculty to immediately redesign their courses for an online modality. This dissertation studied faculty who used Canvas as their Learning Management System to investigate how faculty leveraged affordances and navigated constraints of the platform, specifically in Pages and Assignments, when they designed and redesigned their courses; how their pedagogical and Canvas training affected their choices; and the ways in which their experiences affected their workload and stress levels. This study employed a three-phase methodology: a) a Qualtrics survey with open and closed-ended questions; b) 11 faculty were interviewed; …

Synthesis And Assessment Of Sustainable Fuels For Transportation And Space Exploration, Katerina Chagoya

Electronic Theses and Dissertations, 2020-2023

As global energy sources transition towards renewable energy, the demand for sustainable fuels has never been greater. The sheer scale of this transition will require numerous solutions to accommodate for the diverse and complex situations worldwide. This dissertation will discuss 3 studies: the utilization of CO2 waste gas to produce fuels sustainably, characterizing biofuels for efficient use in automobiles, and developing a solid, emissonless fuel intended for spaceflight but also applicable on Earth. The hydrogenation of CO2 into value-added molecules could reduce greenhouse gas emissions if waste stream CO2 were captured for conversion. We found that atomic vacancies induced in …

The Case Of Tom Tiger's Horse: An Early Foray Into Indian Rights, Harry A. Kersey, Jr.

Florida Historical Quarterly

At a time in our national history when the American Indian’s claim to social and political justice is being vigorously pursued, and dramatically portrayed through mass media coverage of incidents such as the occupation of Alcatraz, disruption at the Bureau of Indian Affairs in Washington, and a “Second Wounded Knee,” it might be well to consider in calmer retrospective one of those little known efforts to secure Indian rights which occurred in Florida at the turn of the century. The participants included an aggrieved Seminole headman of the Cow Creek band and his white friends who displayed an unusual zeal …

Florida's Image In Juvenile Fiction, 1909-1914, Peter A. Soderbergh

Florida Historical Quarterly

In the years between Appomattox and Sarajevo many young readers took their leisure pleasures from the pages of hardbacked novelettes. More respectable, to parents at least, than the "dime novel," the novellas exploded with the heady escapades of fictional boys and girls whose mental and physical reserves were unlimited. Descended from earlier models created by Martha Finley and William T. Adams— and rooted in the "success" ethos popularized by Horatio Alger, Jr.— the series published after 1898 outdid their prototypes in every aspect but quality.
