Stepping Into The Past: A Spatial And Temporal Analysis Of Charleston’S Streetscape Through Imagery, Travis Galli

All Theses

The tradition of preservation has long focused on the built environment of historic buildings, while ignoring the very environment they reside in, specifically streetscapes. This thesis seeks to identify the spatial and temporal changes in streetscapes occurring on King Street and Chalmers Street from 1700 until 1971 and provide guidelines for the preservation and restoration of streetscapes to their periods of historic significance between ca. 1750-1971. By collecting and analyzing images of the streetscape at different period in time, specific features and materials were identified. Imagery included historic photos, paintings, and sketches. Broken into specific periods, this study tracks changes …

Identification Of Genetic Variants Underlying Maxillary Canine-Tooth Mesioversion And Small Body Size In Shetland Sheepdogs, Sydney R. Abrams

All Theses

The domesticated dog (Canis lupus familiaris) exhibits a unique population structure, with high levels of genetic homogeneity within breeds due to selective breeding. These closed breeding populations can result in breed-specific inherited disorders. Maxillary canine-tooth mesioversion (MCM) is a genetically complex dental anomaly observed nearly exclusively in the small Shetland Sheepdog breed. Here, we utilized a genome-wide approach to discover a locus of major effect on chromosome 9. Using whole-genome resequencing data from a bilaterally affected dog, we identified variants in two genes: FTSJ3, encoding an RNA methyltransferase, and GH1, encoding growth hormone. Independent genome-wide association …

Design Of A Four Channel Pulsatile Perfusion Bioreactor For Ex-Vivo Study Of Vascular Grafts, Thomas M. Fair

All Theses

Cardiovascular diseases are the leading cause of death in the United States. Atherosclerosis in peripheral arteries is a major contributing factor. Autologous saphenous vein grafts are the most common bypass grafts for treating peripheral artery diseases. A quarter of these grafts fail within a year, and around half have failed within 10 years of the initial surgery. Graft failure is attributed to the development of intimal hyperplasia indicated by the migration and proliferation of vascular smooth muscle cells, fibroblasts, and the deposition of extracellular proteins.

Increases in flow, pressure, the pulse frequency, and the differential of pressure that model an …

An Experimental Analysis Of Thin Sheet Metal Bending By Ultrafast Laser Peen Forming, Bryce J. Tessmann

All Theses

This study demonstrates the viability of femtosecond laser peen forming for bidirectional sheet metal bending. Ultrafast laser forming is a valuable method thanks to its flexibility, negation of springback, no need for a confining or protective layer, and minimalization of thermal degradation in comparison to other forming processes. However, femtosecond lasers have traditionally been believed to be unsuitable for laser forming in comparison to nanosecond lasers, particularly bidirectional bending, because the induced shock waves were expected to be weak. Conversely, in this study it is elucidated that the femtosecond laser-induced shock waves are extremely strong (several hundred GPa) but the …

This qualitative comparative case study reports on findings from a pre-and post-occupancy evaluation using multiple data collection methods to explore how classroom design features contribute to behavioral outcomes for children with ASD. Ten children, ages three to five years older with ASD, were observed over four months as they transitioned from their current classrooms into their newly built classrooms based on evidence-based design for children with ASD. For a two-month period in each setting, environmental conditions were tracked continuously in both classrooms. In addition, interviews were conducted with the special education teachers in both settings to gain insight into the …

Elucidating The Cellular Physiology Of Glyphosate Resistance In Palmer Amaranth (Amaranthus Palmeri) Using Integrated Omics Approaches, Pawanjit Kaur Sandhu

All Theses

The evolution of resistance to herbicides in weeds poses a major threat to agricultural production systems. To date, herbicide resistance has been reported against 21 modes of action in 266 weed species across 71 countries. More than 50 weed species have developed resistance against glyphosate, the most widely used herbicide worldwide. Although several mechanisms of glyphosate resistance have been discovered, our understanding of alterations in the cellular physiology of glyphosate-resistant weed biotypes, and the induction of the resistance mechanisms remains limited. This knowledge is critical to developing sustainable weed management practices and for a comprehensive understanding of plant stress adaptations. …

Portable U-Bent Optical Fiber Biosensor For Detecting Microcystin-Lr, Quan Dio Anh Le

All Theses

Cyanobacteria are the only known prokaryotes that can photosynthesize. Due to their unique ability, they are important entities in the global carbon and nitrogen cycles. However, two factors can turn cyanobacteria into a nuisance. In general, eutrophication is the process that supplies external nutrients that are needed for cyanobacteria blooms into bodies of water from the surrounding environment. Climate warming intensifies this process by producing carbon dioxide, methane, and nitrous oxide. With cyanobacteria blooms occurring worldwide, they are becoming a bigger threat to human health, and there has been increased interest in detecting cyanobacteria and their toxic byproducts.

For instance, …

Female Portrayal In Games Through Costumes: Designing And Creating Appealing Armor For Female Players, Nancey Fang

All Theses

This thesis details the design, development, and creation of variations of more functional female armor designed for games with the female audience in mind.

The goal is to empower female players by designing and creating strong armor that is not sexualized and that women can enjoy. I want to show that women can be portrayed as strong and powerful in games by designing armor that is equivalent to their male counterparts. Due to the gender imbalance in the video game industry and player base, it seems that female players are not catered to when most games are created. Many studies …

Rewriting The Narrative That Surrounds Mental Illness, Ashley Johnson

All Theses

The focus of this work is to change the narrative that surrounds mental health issues by portraying mental battles through animation. Buddhism heavily influenced the crux of this project, which is the conscious decision to accept oneself and choose to work towards inner balance instead of battles. 3D animation is used to distill complex thoughts into simplified characters that drive the narrative through performance and choreographed fight scenes.

A Quantitative Comparison Of Algorithmic And Machine Learning Network Flow Throughput Prediction, Cayden Wagner

All Theses

Applications ranging from video meetings, live streaming, video games, autonomous vehicle operations, and algorithmic trading heavily rely on low latency communication to operate optimally. A solution to fully support this growing demand for low latency is called dual-queue active queue management (AQM). Dual-queue AQM's functionality is reduced without network traffic throughput prediction.

Perhaps due to the current popularity of machine learning, there is a trend to adopt machine learning models over traditional algorithmic throughput prediction approaches without empirical support. This study tested the effectiveness of machine learning as compared to time series forecasting algorithms in predicting per-flow network traffic throughput …

Investigations Of External Resources And The Impact Of Imaging On Patient Flow In The Emergency Department, Marisa Shehan

All Theses

The problems associated with Emergency Department (ED) crowding are numerous, varied, and complex. Though overcrowded Emergency Departments are frequently attributed to overcrowded hospitals, crowding is also impacted by bottlenecks in patient flow. While discrete-event simulation (DES) is commonly used to model ED flow, external resources are typically excluded from these models due to their complexity and the limited amount of known information for these processes. Instead, external resources such as consults, labs, and imaging are modeled using estimation and/or educated guesswork. In this study, the impact of imaging on patient flow was assessed through data analysis of specific imaging factors, …

Covid-19 And Canine Travelers: Determining Likelihood To Travel With Dogs, Angela Rowan

All Theses

During the Covid-19 pandemic, dog adoption rates skyrocketed, restaurants focused on outdoor seating, and travelers pivoted away from tightly packed planes out of safety concerns. This study surveyed dog owners in the United States to determine whether pet attachment levels could predict dog owners’ likelihood of traveling with their dogs. In addition, it used Um and Crompton’s (1992) facilitators and inhibitors to establish how different factors affect a dog owner’s likelihood of traveling with their dog. These facilitators and inhibitors were split into three dimensions: needs satisfaction, social agreement, and travelability. Finally, this study sought to learn what effect the …

In The Grip Of Grippe: The 1918 Influenza Pandemic Viewed Through A Cross-Section Of American Society, Carole C. Thomas

All Theses

In 1918, a virulent strain of influenza swept the world, infecting as many as 500 million people and killing at least 50 million, 675,000 of whom were in the United States. Despite the many advances that had been made in science and medicine, even the best medical professionals were helpless against the disease. Lawmakers, too, were limited in what they could do to respond to the emergency, especially as the demands of the First World War remained a priority. Through an examination of the response to the flu in a cross-section of American society– national, state, and local – this …

Identification Of Critical Points For Bacterial Contamination In The Microbrewery Environment, Alex Ryan Thompson

All Theses

There are 8,884 craft breweries producing over 23 million barrels of beer in the United States as of 2020. These 23 million barrels of craft beer account for 12.3% of the United States beer consumption in 2020. The American craft beer industry is substantial and needs to protect its product from bacterial contamination.

Overall, beer is a microbially stable product. Beers pH, ethanol levels, CO₂ concentrations, the presence of hop-derived antimicrobial compounds, and low levels of O₂ make beer a highly unfavorable environment for most bacterial species. Furthermore, the brewing process, which involves heat treatments and chemical sanitizers …

Effects Of Prescribed Fire Seasonality On Forest Structure And Bird Populations In The Southern Appalachians, Allison Melcher

All Theses

Decades of fire suppression have contributed to the loss of historical ecosystems and to the decline of wildlife populations throughout the Southern Appalachian region. Recognizing the importance of fire in enhancing habitat and wildlife diversity, forest managers in recent years have begun implementing fire as a management tool to recover traditional disturbance regimes. Most of these burns take place during the dormant season, but some research has indicated dormant season burns are not effective in restoring ecosystem heterogeneity, and there has been a push to expand the use of fire into the growing season. However, much is still unknown about …

Co-Habitation And Migration: Urban Design For Bird Migratory Pathways, Steve C. Kurtz

All Theses

Urban landscapes are intricate systems interacting throughout the globe. Over the past decades, urban development has widely sprawled and fragmented flyway systems and corridors. This has led to many changes in species composition and has even caused the extinction of some animals (Marzluff 1997). Recent studies have indicated that there exists a protective or restorative design to create stepping-stone connectivity in urban areas. This study looks to understanding potential benefits in urban biodiversity, animal species protection, and urban benefits of green roof designs.

Immigration Detention And Illusory Alternatives To Habeas, Fatma Marouf

Faculty Scholarship

The Supreme Court has never directly addressed whether, or under what circumstances, a writ of habeas corpus may be used to challenge the conditions of detention, as opposed to the fact or duration of detention. Consequently, a circuit split exists on habeas jurisdiction over conditions claims. The COVID-19 pandemic brought this issue into the spotlight as detained individuals fearing infection, serious illness, and death requested release through habeas petitions around the country. One of the factors that courts considered in deciding whether to exercise habeas jurisdiction was whether alternative remedies exist, through a civil rights or tort-based action. This Article …

The Truth About Design Patents, Sarah Burstein, Saurabh Vishnubhakat

Faculty Scholarship

Design patents are hot. Scholars and policymakers are increasingly focusing on this once-niche area of law. However, many of the empirical studies in this area—including old ones that still get cited—were methodologically questionable from the start, have become outdated, or both. In this Article, we make two sets of contributions to this important and underdeveloped literature. First, we review the empirical studies of design patents thus far, including those that pre- and post-date the creation of the U.S. Court of Appeals for the Federal Circuit, and we update the findings of those studies. Second, we consider a set of institutional …

Department of Surgery

Early burn excision and skin grafting have been essential to improving patient outcomes following a burn injury. However, there remain significant barriers to recovery for burn patients, especially in the post-discharge period, as follow-up care is essential to the timely identification of complications. While the infection is a common complication of a post-burn wound,

Deep Depression Prediction On Longitudinal Data Via Joint Anomaly Ranking And Classification, Guansong Pang, Ngoc Thien Anh Pham, Emma Baker, Rebecca Bentley, Anton Van Den Hengel

Research Collection School Of Computing and Information Systems

A wide variety of methods have been developed for identifying depression, but they focus primarily on measuring the degree to which individuals are suffering from depression currently. In this work we explore the possibility of predicting future depression using machine learning applied to longitudinal socio-demographic data. In doing so we show that data such as housing status, and the details of the family environment, can provide cues for predicting future psychiatric disorders. To this end, we introduce a novel deep multi-task recurrent neural network to learn time-dependent depression cues. The depression prediction task is jointly optimized with two auxiliary anomaly …

Context Modeling With Evidence Filter For Multiple Choice Question Answering, Sicheng Yu, Hao Zhang, Wei Jing, Jing Jiang

Research Collection School Of Computing and Information Systems

Multiple-Choice Question Answering (MCQA) is one of the challenging tasks in machine reading comprehension. The main challenge in MCQA is to extract "evidence" from the given context that supports the correct answer. In OpenbookQA dataset [1], the requirement of extracting "evidence" is particularly important due to the mutual independence of sentences in the context. Existing work tackles this problem by annotated evidence or distant supervision with rules which overly rely on human efforts. To address the challenge, we propose a simple yet effective approach termed evidence filtering to model the relationships between the encoded contexts with respect to different options …

Indoor Localization Using Solar Cells, Hamada Rizk, Dong Ma, Mahbub Hassan, Moustafa Youssef

Research Collection School Of Computing and Information Systems

The development of the Internet of Things (IoT) opens the doors for innovative solutions in indoor positioning systems. Recently, light-based positioning has attracted much attention due to the dense and pervasive nature of light sources (e.g., Light-emitting Diode lighting) in indoor environments. Nevertheless, most existing solutions necessitate carrying a high-end phone at hand in a specific orientation to detect the light intensity with the phone's light sensing capability (i.e., light sensor or camera). This limits the ease of deployment of these solutions and leads to drainage of the phone battery. We propose PVDeepLoc, a device-free light-based indoor localization system that …

The Ethical Dilemmas Of The True Crime Genre, Jordan Smail

Marketing Undergraduate Honors Theses

Along with the recent mainstream popularity of true crime entertainment, the genre has been increasingly criticized for ethical violations. Interestingly, the centuries-long history of true crime and the moral debates around it has led to an abundance of literature on the subject with little to no consensus. The mere existence of true crime entertainment can even be considered controversial in some cases. For those who produce and market true crime content, a lack of common guidelines means receiving a wide range of feedback. This dichotomy of both backlash and praise being published about the same works reveals a gap in …
