Decision-Making For Vehicle Path Planning, Jun Xu

Electronic Theses and Dissertations

This dissertation presents novel algorithms for vehicle path planning in scenarios where the environment changes. In these dynamic scenarios the path of the vehicle needs to adapt to changes in the real world. In these scenarios, higher performance paths can be achieved if we are able to predict the future state of the world, by learning the way it evolves from historical data. We are relying on recent advances in the field of deep learning and reinforcement learning to learn appropriate world models and path planning behaviors. There are many different practical applications that map to this model. In this …

Measuring Player Perceptions Of Freedom And Control In Modded And Unmodded Versions Of Bethesda's Skyrim: A Qualitative Play Study, Mark Kretzschmar

Electronic Theses and Dissertations

This interdisciplinary dissertation explores perceptions of control in modded and unmodded versions of Bethesda's sandbox video game Skyrim. Sandbox games are known for greater choice options that suggest greater perceptions of control for gamers. Sandbox games also generally encourage the use of user-generated creations called modifications (mods) that users can download to personalize their games. While we need philosophy to understand and define control as a concept, we also need psychology to understand how users perceive control in media studies. At present, qualitative academic research that measures gamer perceptions of control is non-existent as is research on how users articulate …

Effloresce, Rebecca Lee Schneller

Electronic Theses and Dissertations

Effloresce is a series of oil paintings and charcoal drawings containing the human figure and natural imagery and forms. This pairing represents the intersection of the inner realm of human emotion and spiritual experience with the external realm of nature and the world.

Both contemporary and historical painting and drawing traditions serve as inspiration for this body of work, particularly the natural symbology found in Medieval and Renaissance Art. I employ painting techniques inspired by contemporary painters Alex Kanevsky, Mia Bergeron, Helene Delmaire, and Zoey Frank, as well as historical painters John Singer Sargent, Joaquin Sorolla, Rembrandt Van Rijn, Lucian …

Changing The Channel: A Study Of Agenda, Immersion And Social Commentary In Art, Nicholas Kalemba

Electronic Theses and Dissertations

This thesis examines the concepts and ideas that pervade my body of work in painting. These concepts include immersion and scale, interactions in space, harmony and disunity, flat and dimensional space and perhaps most importantly, ambiguity. I intentionally use these formal devices to create immersive environments that appear as a familiar but skewed version of reality. By forcing together disparate languages of visual representation into the theoretical space of a painting, I strive to expose some of the humor and decay of our social institutions. In using the format of collage, my paintings have the opportunity to incorporate a wide …

Exploration Of Life And Decay In Technological Civilization, Mauro Wieser

Electronic Theses and Dissertations

Reflecting upon humanity's obligatory use of technology and its place in our collective evolution has become my endeavor. These reflections happen in a studio and through a process that influences the fine art objects produced. In turn the objects both celebrate and warn us of the dynamic and immanent enhanced human. I balance the use of modern machining processes with dark humor to comment and raise questions about the coexistence of man and machine in an increasingly absurd environment.

Designosaurs: Technological Evolution And De-Extinction Through An Advancing Medium, Sean Vanzyl

Electronic Theses and Dissertations

This thesis is an examination of my imperative need to understand dinosaurs and their role in science and art, acting as prehistoric symbols for science and imagination. Like our understanding of dinosaurs, my body of work is evolving simultaneously with the technology of our time. Through the synthesis of artistic language with science and technology, I create dynamic experiences allowing a viewer to witness an extinct living being in its entirety, an otherwise lost experience. By utilizing digital modeling, animation techniques, and interactive video games, my work speaks to the power and diversity of digital media's role in visualizing artifacts …

From The Temple To The Synagogue: Exploring Changes In Judaism After The Fall Of The Second Temple, Adam Cohen

Electronic Theses and Dissertations

"From the Temple to the Synagogue" is an analysis on the influence of external cultures, predominantly the Persian religion of Zoroastrianism on the early rabbis following their failed revolt against Rome and the destruction of the Second Temple in the first century CE. How did the Jewish people react to the upheaval of their center of worship? What can we attribute to the major changes in their religious literature and centers of worship following the demise of their rebellion? Is it possible that what has traditionally been seen as an isolated and uniform group of people did in fact borrow …

Pine, Aphids, And Parasitoid Wasps: Patterns Of Cospeciation And Host Switches In A Tri-Trophic System, Amber Bass

Electronic Theses and Dissertations

Ecological interactions may drive speciation events, and the processes that drive these speciation events can leave behind patterns in the phylogenies of interacting taxa. These patterns have been studied extensively in herbivores and host plants, as well as parasites and their hosts, but rarely in tri-trophic systems. Here, we examine three closely related groups of interacting taxa, including parasitoid wasps (Pauesia), aphid herbivores (Cinara), and pine trees (Pinus) to determine if the patterns between each interacting taxa indicate that cospeciation or host switches are more dominant. We create phylogenies of Cinara and Pauesia in the southeastern United States using ddRADseq …

In this thesis, The Mountaintop, written by Katori Hall, is used as a gateway to conduct research on music and rhythm as it affects the body and creating physical character choices. By reflecting on personal musical exploration,that of my peers, and students, its concluded that this method can be used for all stages of character building and performance experiences. The various backgrounds of the subjects — students and peers — …

Glycine Receptor Expression Across Identified Retinal Ganglion Cell Types., Ian Scot Pyle

Electronic Theses and Dissertations

Retinal ganglion cells (RGCs) represent the culmination of all retinal signaling and their output forms the substrate for vision throughout the rest of the brain. About 40 different RGC types have been defined by differences in their visually evoked responses, morphology, and genetic makeup. These responses arise from interactions between inhibition and excitation throughout the retinal circuit (Franke et al., 2017; Masland, 2012; Sanes & Masland, 2015; Werblin, 2011). Unlike most other areas of the central nervous system (CNS), the retina utilizes both GABA and glycine inhibitory neurotransmitters to refine glutamatergic excitatory signals (Franke & Baden, 2017; Werblin, 2011; C. …

"A Trained And Trustful Soul" : Life And Literature Of A Black Louisville Artist In Minstrel America., Emma Christine Bryan

Electronic Theses and Dissertations

This thesis explores the century-long theatrical expression of blackface minstrelsy within the larger context of the United States, but specifically studies its popularity in Louisville, Kentucky from 1878 to 1925. This study is meant to bring to the fore the pervasiveness of blackface minstrelsy, and how it was used to demean, degrade, and oppress African American populations before, during, and well after Emancipation. This work is not meant to memorialize the craft of minstrelsy, however, but rather attempts to show how black individuals of the time were actively working to both reclaim the detrimental stereotypes of blackface minstrelsy, while also …

All The Better To See You With., Monica Stewart

Electronic Theses and Dissertations

All the Better to See You With is a body of work that deals with the inherently complex relationships between fairy tales and feminism. Consisting of an installation of hand-embroidered life-size or larger, papier-mâché female body parts and a series of six mixed media works on paper, this collection of work uses the imagery of fairy tales to address the violence of female experience. Through an exploration of the role of women in both the writing and literary function of fairy tales, we can see connections between the truth and fiction of women’s work and violence against women.

Inspiratory Muscle Recruitment During Swallow And A Comparison Across Airway Behaviors., Allison V. English

Electronic Theses and Dissertations

During swallow, a negative esophageal pressure is present that, along positive pressure from the tongue, which works to move the bolus through the pharynx into the esophagus. This negative esophageal pressure is thought to be produced via recruitment of chest wall inspiratory muscles (diaphragm and parasternal). This current study aimed to examine respiratory muscle recruitment across behaviors which have known inspiratory muscle activity (eupnea, augmented breath and cough) and compare to swallow. It was hypothesized that there would be no significant difference in amplitude and muscle recruitment over 75 ms between swallow and eupnea, but cough and augmented breath would …

Coming To Terms With Gonzo Journalism : An Analysis In Russian Formalism., Beau Kilpatrick

Electronic Theses and Dissertations

Gonzo journalism is notoriously difficult to define because of its ambiguous nature. To date, scholarly definitions focus on historical interpretations of Gonzo’s content, its connection to social and political contexts, or the biography of Hunter S. Thompson. These definitional attempts neglect the formal devices of the composition. This thesis aims to redefine Gonzo as its own genre by using the nearly forgotten methods of Russian formalism—specifically the works of Victor Shklovsky, Vladimir Propp, and Boris Tomashevsky—to analyze the formal devices and components of its form. The results are twofold; first, it acts to rejuvenate an unpopular literary theory by illustrating …

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …

Thinging : Powerful Objects., Tammy M. Burke

Electronic Theses and Dissertations

The works in "Thinging” are inspired by desire, the genuine and the false, systems of real and perceived values, the quest for immortality, the allure of things, our use of them to make ourselves, and imagining pasts and futures via objects. The following concepts are threaded through the work: cathexis, ritual as a value builder, collections, hoarding, display, object history, exchange, use, and sign values, and vibrant materiality. At the heart of my investigation is the quest to examine the origins of object power, and by what measures it can be evaluated: value from belief, market value, and something perhaps …

The Q Rule In Bacteriodetes And The Identification And Characterization Of Porphyromonas Gingivalis Glutaminyl Cyclase., John Andrew Houston

Electronic Theses and Dissertations

Background: Porphyromonas gingivalis, a major pathogen associated with chronic periodontitis, secretes variety of proteins, majority of which begins with glutamine. Several of these proteins were found with pyroglutamate (pGlu) at N-terminus suggesting the presence of this posttranslational modification pathway in P.gingivalis. The observation that N-terminal glutamine is over-represented as the first amino acid after signal peptide cleavage, and subsequent confirmation of pGlu formation on the nascent protein via mass spectrometry, led us to conclude that an enzyme must be present as the executor of this reaction. Hypothesis: PG2157 is a glutaminyl cyclase and is responsible for the cyclization of …

Alterations In Rhythmic Licking Behaviors Following Fibrosis In The Rat Mylohyoid Muscle., Brittany Fletcher

Electronic Theses and Dissertations

Muscle injury is a common side effect of radiation treatment for head and neck cancer. To increase understanding of muscle injury related dysfunction, we investigated the effects of oral swallowing function after cryoinjury to mylohyoid muscle in rats. The hypothesis is that injury to the mylohyoid delays the temporal licking pattern, resulting in aberrant drinking behaviors. Six rats received bilateral mylohyoid injuries by applying a 3mm cryoprobe. Licking behavior was measured by electrophysiological recordings of rhythmic tongue movements in a ten-minute drinking session taken pre-and post-injury (one-and two-weeks). Lick frequency and total licks per cluster decreased significantly one-and two-weeks post-injury …

Discourses In Practice : A Qualitative Case Study Of An Elementary Esl Teacher And Her Four Congolese Students., Emily Lynn Zuccaro

Electronic Theses and Dissertations

In this qualitative case study, I examine the ideological becoming—the ways individuals develop their beliefs and ways of viewing the world—of an English as a Second Language (ESL) newcomer literacy teacher and her four Congolese students. These individuals developed beliefs about their identities as a teacher of culturally and linguistically diverse children and students in U.S. schools. I situate my study in Bakhtinian sociocultural theory and draw on translanguaging theory to account for language learners’ creative and flexible uses of their language knowledge in different contexts. Ideological becoming occurs between the tension of authoritative and internally persuasive Discourses (Gee, 2014)—ways …

Development Of A Lectin-Fc Fusion Protein With Antiviral And Anti-Cancer Activity., Matthew William Dent

Electronic Theses and Dissertations

This thesis describes the development of a novel lectin-Fc fusion protein and its antiviral and anti-cancer activity. The molecule, Avaren-Fc (AvFc), is a fusion of a variant of the actinomycete lectin actinohivin (Avaren) and the Fc region of human IgG1, and is selective for the terminal α1,2-mannose residues found at the ends of high-mannose-type glycans that can be found on the surface of certain heavily glycosylated viruses and cancer cells. Here, AvFc was found to be able to neutralize simian immunodeficiency virus as well as Hepatitis C virus with nanomolar IC₅₀ values. Furthermore, AvFc recognizes a number of cell …

Paraoxonase 2 Is Critical For Non-Small Cell Lung Carcinoma Proliferation., Aaron Whitt

Electronic Theses and Dissertations

Non-small cell lung carcinoma (NSCLC) comprises 85% of lung cancer diagnoses and is plagued by drug resistance. Thus, elucidating the underlying mechanisms of NSCLC is paramount to expand future treatment options. Paraoxonase 2 (PON2), an intracellular enzyme with arylesterase and lactonase functions, has well-established anti-atherosclerotic activity. Recent studies show PON2 is overexpressed in a variety of tumors and confers drug resistance, although these interactions have not been thoroughly examined in NSCLC. Thus, we sought to investigate the role of PON2 in cellular proliferation using PON2-knockout mice, primary mouse cells, and NSCLC cell lines. Using these approaches, we demonstrate that PON2 …

Balancing Exploration, Exploitation, And Efficiency : A Framework Of Entrepreneurial Learning., Shaun Paul Digan

Electronic Theses and Dissertations

Entrepreneurial learning (EL), defined as “learning in the entrepreneurial process through which individuals acquire new knowledge, either vicariously or from direct experience, which has the potential to change the range of entrepreneurial actions”, is a key construct in the pursuit and development of entrepreneurial opportunities. However, the field of entrepreneurship has yet to produce a theory of learning explaining under what conditions individuals engage in differing types of entrepreneurial learning. Further, the limited research within this line of inquiry is diverse and disconnected. In this research, I attempt to advance the literature on organizational and entrepreneurial learning through the examination …

This To Which We've Come., Holly Tabor

Electronic Theses and Dissertations

This collection of works explores the linkages between moments, the connective thread that accumulates over time to create for each of us a unique present. The title, “This to Which We’ve Come,” attempts to convey that each moment is a point of arrival colored by the smallest of temporal fibers, our most interior histories that stretch and bend and fold back onto themselves when the present forces us into action, or inaction. Through these characters and their stories, I attempt to examine that moment of arrival. A secondary thread explored in this collection is the idea that humans are still …

Receptive Fields Optimization In Deep Learning For Enhanced Interpretability, Diversity, And Resource Efficiency., Babajide Odunitan Ayinde

Electronic Theses and Dissertations

In both supervised and unsupervised learning settings, deep neural networks (DNNs) are known to perform hierarchical and discriminative representation of data. They are capable of automatically extracting excellent hierarchy of features from raw data without the need for manual feature engineering. Over the past few years, the general trend has been that DNNs have grown deeper and larger, amounting to huge number of final parameters and highly nonlinear cascade of features, thus improving the flexibility and accuracy of resulting models. In order to account for the scale, diversity and the difficulty of data DNNs learn from, the architectural complexity and …

An Assessment Of Sustainability In Jefferson County Public Schools (Kentucky)., Elizabeth Ann Ruhe

Electronic Theses and Dissertations

Schools play a vital role in preparing the next generation of citizens to be active, engaged, creative thinkers and problem-solvers. Schools are also large institutions in their communities, employing many people and spending large sums of money. What happens in schools has an impact on their surrounding communities. Human behaviors are having a significant impact on our planet and changes in our society are affecting the sense of safety and security of our citizens. These are aspects of sustainability that schools need to begin addressing. This research looks at sustainability practices in a large urban school district to document current …

The Elite Meroitic Experience On Sai Island, Sudan: Using Stable Isotope Analysis To Identify Patterns Related To Sex And Age For The Interpretation Of Social Identity, Alexandria Brock

Electronic Theses and Dissertations

The research conducted for this thesis utilized stable isotope analysis to reconstruct the diet of 35 individuals from an elite Meroitic (350 BC – 300 AD) cemetery (site 8.B.5A) located on Sai Island, Sudan, with a focus on adult age categories and biological sex, to understand intraclass variation in diet. Stable carbon and nitrogen values from human bone collagen were used to understand elite social organization, social practice, and gender roles in the Meroitic period through the lens of social identity and post-processual theories. The samples were grouped based on biological sex, median age, and assigned age categories (young, middle, …

Electronic Theses and Dissertations

Sea level rise (SLR) has become a serious threat for coastal communities in recent years. Many communities, including South Florida, are already having the security of their daily lives impacted as climate change causes SLR and other environmental impacts to worsen. This study reviews the Miami-Dade Sea Level Rise Task Force Report to determine how this coastal county government views SLR as a threat. Using mixed content analysis to analyze the report qualitatively and quantitatively, the Task Force's recommendations are categorized based on their focus on security, infrastructure, economics, and the environment. One finds the concerns of the people to …

Do Per-Capita Impact Or Abundance Dominate The Impact Of An Invader? Interactions Among Neighboring Species In Context-Dependent Competition, Haoyu Li

Electronic Theses and Dissertations

Evaluating relative species competitive strength is a central question in community ecology, with strong implications for invasion ecology. Models assessing invader success consider three components: distribution, abundance and per-capita impact. However, relative strength and interactions among these factors remain unclear when applying to specific invasion scenarios. We hypothesized that performance of native and non-native species will vary as a function of direct and indirect effects at different abundances and scales. We conducted a replacement experiment between two dominant grasses in subtropical grasslands (the native Axonopus fissifolius and the non-native Paspalum notatum) in central Florida, USA. Thirty fenced plots (1 m …

Realtime Editing In Virtual Reality For Room Scale Scans, Charles Greenwood

Electronic Theses and Dissertations

This work presents a system for the design and implementation of tools that support the editing of room-scale scans within a virtual reality environment, in real time. The moniker REVRRSS ("reverse") thus stands for Real-time Editing (in) Virtual Reality (of) Room Scale Scans. The tools were evaluated for usefulness based upon whether they meet the criterion of real time usability. Users evaluated the editing experience with traditional keyboard-video-mouse compared to a head mounted display and hand-held controllers for Virtual Reality. Results show that users prefer the VR approach. The quality of the finished product when using VR is comparable to …
