License Plate Image Quality Enhancement Utilizing Super Resolution Generative Adversarial Networks, Mark Moelter

College of Graduate Studies: Theses & Dissertations

This thesis focuses primarily on enhancing the image quality of blurred license plates through the use of Super-Resolution Generative Adversarial Networks (SRGANs) [1]. We propose a synthetic dataset with SRGAN model to promote blurred image quality enhancement, and allow for model evaluation on a multitude of image input and output size combinations. SRGAN is mainly used for low-resolution image enhancement, but by heavily blurring the input images, the model is tested on its ability to blindly deblur and upsample images to the desired super-resolution (SR) size. The model enhances the image quality to nearly that of the reference images. The …

Population Genomics Of Redbreast Sunfish (Lepomis Auritus): Exploring Gene Flow And Local Adaptation In A Widely Distributed Freshwater Fish, Garret J. Strickland

College of Graduate Studies: Theses & Dissertations

Little information is available concerning the distribution of genetic diversity in non-salmonid, non-imperiled, freshwater fish. In order to fill in this knowledge gap, I conducted a population genomics survey in Redbreast Sunfish (Lepomis auritus; RBS), a widespread, generalist species distributed along the Atlantic slope rivers of eastern North America. I sampled four basins (ACF, Savannah, Roanoke, and James) at eight sites each with a factorial experimental design. Sites were distributed among coastal plain, Piedmont, or mountain ecoregions in order to capture the greatest range of environmental states experienced by RBS, with the intention of finding evidence for local adaptation to …

Synthesis And Characterization Of Multimetallic Clusters Featuring Iron, Cobalt, And 2,6-Bis(Trialkylsilylamino)Pyridines, Lynn Nguyen

College of Graduate Studies: Theses & Dissertations

Extended metal atom chain (EMAC) complexes are multimetallic complexes of three or more metals, often containing M-M bonds, with the metal ions arranged linearly. These complexes have significant potential as molecular wires. They can elicit unique physical properties and reactivities, sometimes a result of direct magnetic exchange between metal centers, especially when incorporating first row transition metals. The synthesis of the first linear, triiron (II) complex with 2,6-bis[(trimethylsilyl)amino]pyridine (H₂L^Me) featuring Fe-Fe bonding from our group, Fe₃L^Me₃, motivated the expansion of linear multimetallic EMAC complexes with Fe and Co, incorporating M-M bonds. …

The Effect Of Magnitude And Probability On Plea Bargain Decision-Making, Megan L. Small

College of Graduate Studies: Theses & Dissertations

Decision-making is studied in various aspects of life and can be especially vital in the context of the criminal justice system, such as plea bargains. Previous research in this area used a less commonly used task (fill-in-the-blank) in addition to a student sample (Falligant & Pence, 2019). The current study uses probability discounting to study the choice between accepting a plea bargain for a shorter incarceration sentence or risking a trial with a longer sentence on a sample of adults with experience in the criminal justice system. Three sentence durations, or magnitudes, were used (1 year, 5 years, and 25 …

Hyphenated Identity And Negotiated Intersectionality: A Memoir Of A First-Generation Nigerian-American Male Teacher In An Inner City Title 1 Elementary School In Georgia, Gerald Chidiebere Nwachukwu

College of Graduate Studies: Theses & Dissertations

This dissertation is a memoir where I tell my stories of negotiating cultures, races, ethnicities, and identities in Nigeria, and in the United States as a first-generation Nigeria American teacher in an inner-city elementary school in Georgia. As a labeled African American upon entry into the United States, I did not understand the meaning of being Black because everybody in Nigeria is Black. In becoming Black, I became racialized, marginalized, and lumped into the African American ethnicity. I was rejected for not being Black enough in the United States nor Nigerian enough in Nigeria. Theoretically, I draw upon a wide …

Nitrate Removal During The Shoulder Months In The Occoquan Reservoir: A Comprehensive Study, Km Risaduzzaman

College of Graduate Studies: Theses & Dissertations

The artificial nitrate addition by the Upper Occoquan Service Authority (UOSA)’s Water Reclamation Facility (WRF) to the Occoquan Reservoir during the warmer months has been proven to be an efficient way of maintaining the water quality of the reservoir. During the warmer months, the water body became thermally stratified, resulting in hypolimnetic anoxia and the subsequent release of undesired matters from the reduced sediments. At the end of the warmer months, the temperature began to decrease, and by the beginning of winter, oxygen became ubiquitous in water because of fall turnover. This condition remained stable until the following thermal stratification; …

College of Graduate Studies: Theses & Dissertations

This study responds to the need for understanding and terminology regarding Black poets’ engagement with the sonnet form. Referring to sampling strategies in Hip-Hop to analyze Black sonnets, this study disputes limiting ideas about sonnets as ineffective mediums to portray Black narratives and honors strategies maintained in Hip-Hop culture that define Black narrative expression, resistance to assimilation, and social reflection. Black sonnets are an ever-evolving vehicle of resistance to elitist ideas about traditional forms, Black aesthetics, and the ways that poetic strategies can be defined. This study names past and present Black sonneteers’ adherence to, remixing in, and rejection of …

Sexual Minority Stress And Mental Health: An Investigation Of Rural-Urban Differences In Social Support, Justin T. Miller

College of Graduate Studies: Theses & Dissertations

As mental health disparities and discrimination facing the LGB (sexual minority) community continues to come into public focus, researchers and clinicians are moving toward identifying LGB-specific mental health interventions to support well-being efforts within this population. Furthermore, much of the current literature on sexual minority mental health is focused on predominantly urban samples failing to consider the sociocultural impacts of living in low resourced and geographically isolated regions of the United States (US). To this end, social support is a promising prevention factor, but few studies to date examine its influence on different minority stress models. As such, the current …

Male Color Badges Advertise Multiple Messages: Tradeoffs Among Color Badge Intensity, Size, And Ectoparasite Load, Katherine M. Roberts

College of Graduate Studies: Theses & Dissertations

Condition-dependent signals can be used by conspecifics to obtain information on an individuals’ quality such as health, fighting ability, or immunocompetence. Variation in the severity of parasitic infections could mediate the differential expression of sexual signals in distinct populations of the same species. This could create diverse condition-dependent relationships between signals and quality. In this study, I examine the relationship between male signal expression and quality of Sceloporus woodi that inhabit areas with distinct ectoparasitic pressures. First, I examined if the brightness or size of male signals is indicative of body size or body condition in males without ectoparasites. Second, …

Epigenetic Buffering In Introduced House Sparrows, M. Ellesse Lauer

College of Graduate Studies: Theses & Dissertations

Epigenetic buffering, as an environmentally induced increase in variance of epigenetic states that increases phenotypic variation to buffer populations against decreased fitness, may be a factor that resolves the genetic paradox of introduced species. DNA methylation is a molecular mechanism that could facilitate epigenetic buffering by changing in response to environmental stress. Therefore, epigenetic buffering can be detected through increased variance in DNA methylation in novel or heterogeneous environments. Introduced house sparrows (Passer domesticus) have well-documented phenotypic changes with low genetic diversity, high epigenetic diversity, and high variance in DNA methylation that provide a characteristic signature of epigenetic buffering. …

Background: Healthcare cost in the U.S. has been increasing at an unsustainable rate due to the growing population diagnosed with multiple chronic conditions and a fragmented healthcare system. The high-risk patient population includes persons who over utilize the healthcare system with frequent avoidable hospitalizations, emergency room visits, and exacerbations of their chronic conditions. This high-risk population makes up five percent of the U.S. but accounts for over fifty percent of all healthcare spending. Care coordination models have emerged to focus proactive health interventions for the highest-risk patient populations to reduce overutilization and empower patients to improve long-term health. Evidence has …

Neosublime, Reframing The Philosophical, Kathy Varadi

College of Graduate Studies: Theses & Dissertations

Why have the sunsets and sunrises become so amazingly colorful and awe inspiring recently? Eighteenth century philosophers said such events were examples of the sublime. They defined the sublime as that which is the most absolutely great combined with an underlying element of fear usually caused by the actions of God. This infers that the sublime is something that you can’t fully understand or wrap your head around and leaves you speechless and spell bound. Contemporary art critics say that the sublime is no longer applicable to art because it has been overused. I disagree, and in my art, I …

Hemocyte-Mediated Immune Response To A Bacterial Infection In The Cat Flea (Ctenocephalides Felis), Melanie Muñoz

College of Graduate Studies: Theses & Dissertations

Despite their continued medical and veterinary importance, the vectorial capacity of fleas (Order Siphonaptera) is often underestimated. Fleas are best described as ectoparasites of a variety of mammalian and aviary hosts. In humans, fleas are infamous for the transmission of several detrimental agents, including those that cause plague, murine typhus, and cat-scratch disease. Although their significance in flea immune responses remains unknown, phagocytic immune cells, known as hemocytes, are important players in the cell mediated immune response of insects. Among invertebrates, hemocytes provide defense against foreign microbes via phagocytosis, cellular encapsulation, and the production of humoral immune factors. As mentioned …

Generation Z’S Proclivity For Technological Communication: An Exploration Into Its Effects On Employers’ Perceptions Of Gen Z And The Intergenerational Workplace, Hannah G. Whitehead

Honors College Theses

Gen Z’s proclivity for digital communication may be putting them at a disadvantage when shifting into professional settings. Generation Z is inclined to communicate differently than Millennials and Generation Y, the two generations that currently make up the largest percentage of the job market. The idea that Gen Z’s future employers prefer different styles of communication creates the risk of negatively influencing these employers’ perceptions of Gen Z’s professionalism and workplace capabilities. By interviewing 12 internship supervisors from varying industries amidst the Southeast who belong to Generations X and Y, the author explores the difference in communication styles between Generation …

The Cowboy Conundrum: An Examination Of Representation Within The Western Film Genre, Madelynn E. Woodard

Honors College Theses

Despite historical demographic data indicating otherwise, much of the Western Film Genre depicts The Cowboy as a white male individual. Previous research has demonstrated that filmmakers often tell and depict stories within which they identify themselves, and with the predominant population of directors within the Western Genre being that of white men, the narrative of the West being portrayed on screen has shifted public perception to an inaccurate portrayal of the history of the West. From Vaqueros to liberated slaves, much of the Cowboy community was comprised of Black, Spanish, Mexican, and Indigenous people of color. This study employed a …
