Optical Control System For Atmospheric Turbulence Mitigation, Martyn Lemon

All Theses

Propagation of laser light is distorted in the presence of atmospheric turbulence. This poses an issue for sensing, free-space optical communications, and transmission of power. With an ever-increasing demand for high-speed data communications, particularly between satellites, unmanned vehicles, and other systems that benefit from a point-to-point link, this issue is critical for the field. A variety of methods have been proposed to circumvent this issue. Some major categories include the manipulation of the light’s structure, an adaptive scheme at the optical receiver, scanning mirror systems, or a transmission of simultaneous signals with a goal to improve robustness.

There is an …

Multiple Objective Function Optimization And Trade Space Analysis, Yifan Xu

All Theses

Optimization can assist in obtaining the best possible solution to a design problem by varying related variables under given constraints. It can be applied in many practical applications, including engineering, during the design process. The design time can be further reduced by the application of automated optimization methods. Since the required resource and desired benefit can be translated to a function of variables, optimization can be viewed as the process of finding the variable values to reach the function maxima or minima. A Multiple Objective Optimization (MOO) problem is when there is more than one desired function that needs to …

Why Can't We Be Friends: A Training Evaluation Of Community Dialogues, Kyle Christenson

All Theses

Demographic and attitudinal diversity can be powerful tools within the team and organizational contexts. However, when not addressed effectively, diversity can greatly strain interpersonal relations and has been found to lead to a number of negative consequences at the individual, team, and organizational levels (Roth, Goldberg, & Thatcher, 2017; Harrison & Klein, 2007). Though there have been attempts to effectively mitigate these negative outcomes, few have found lasting success (Kessler, 2021). However, a training for students offered at a university nested in the southeastern region of the United States offers a relatively novel approach to handling these interpersonal differences. The …

Venomic Characterization Of A Medically Relevant Rear-Fanged Snake, Conophis Lineatus (Dipsadidae: Xenodontinae), From Middle America, Tristan Schramer

All Theses

Most traditional research on snake venoms has focused on front-fanged snake families (Viperidae, Elapidae, and Atractaspididae). However, venom is now generally accepted as being a much more broadly possessed trait within snakes, including species traditionally considered harmless. Unfortunately, due to historical inertia and methodological challenges, the toxin repertoires of non-front-fanged snake families (e.g., Colubridae, Dipsadidae, and Natricidae) have been heavily neglected despite the knowledge of numerous species capable of inflicting medically relevant envenomations. Integrating proteomic data for validation, we perform a de novo assembly and analysis of the Duvernoy’s venom gland transcriptome of the Central American Road Guarder (Dipsadidae: Xenodontinae: …

Impact Of Housing And Management On Production, Behavior, And Welfare Of Dairy Cows In Automatic Milking Systems, Lindsey Eve Davis

All Theses

The overall objective of this research was to determine the impact of Automatic Milking System (AMS) housing and management practices on cow production, behavior, and welfare of Holstein dairy cows. The first objective was to identify factors at the farm and cow level associated with lameness on AMS farms through decision tree analysis to allocate probabilities to each input. Results indicated this novel multifactorial approach of data analysis enabled us to highlight critical points that can be focused on to lessen cow-level complications or enhance farm-level housing and management practices to reduce the incidence and severity of lameness in AMS …

Cover Cropping And Organic Amendments To Improve Sandy Soils Under Organic Vegetable Production, Charles Williamson

All Theses

Coastal Plain soils in the Southeastern USA are typically sandy with poor soil structure, low soil organic carbon (SOC) content, and meager soil fertility that pose challenges to organic agriculture. Adding organic inputs is a strategy to improve these soils' physical, chemical, and biological characteristics. Here, we aim to investigate the impacts of Cover Cropping (CC) and manure inclusions on sandy soils under organic vegetable production. The experiment design was a randomized complete block with two treatments of manure application (with and without) and four CC treatments of cereal rye (Secale cereale), hairy vetch (Vicia villosa), …

If You Give A Beetle A Maple: Anoplophora Glabripennis Habitat Selection Patterns On An Island In South Carolina, Meredith Bean

All Theses

At the epicenter of the Asian longhorned beetle (Anoplophora glabripennis Motschulsky) quarantine zone in South Carolina, a small island containing an actively growing subpopulation of A. glabripennis had not completely killed its 37 host trees in 2020. Before these trees were removed and destroyed according to the USDA Eradication Program protocols, I performed an observational study to examine the microhabitat selection tendencies of the invasive A. glabripennis within this satellite infestation. After cataloging >14,000 oviposition sites and >1,600 exit holes created by A. glabripennis, I found dispersal trends according to a host’s stem status (single or multi-stemmed), vertical …

An Evaluation Of Bovine Reproductive Function From The Microrna Expression In The Female To Performance Testing In The Male, Erin Amiss

All Theses

Reproductive function is crucial to the success of a beef or dairy herd. Both the female and male play significant roles in the outcome of bovine reproduction. The bull contributes to reproductive success in many ways, such as genetics. The initial role that the bull has in reproductive success is fertilization, whether natural or by artificial insemination. One method of assessing bull performance are central bull test stations, which are traditionally administered by a university, extension center, or are privately owned. Central bull tests assess the performance of bulls from various management systems, breeds, and ages. Some measurements taken during …

Barriers And Facilitators In Implementing Multiplatform Remote Patient Monitoring Of Heart Failure Patients In Clinical Settings, Zachary Andrew Reilly

All Theses

Remote patient monitoring (RPM), which provides continuous monitoring of vital signs, has become increasingly utilized in patients with heart failure (HF). As this condition impacts more than 26 million Americans each year, it is important to determine the barriers and facilitators of RPM to both improve patient care and help medical professionals make more informed medical decisions. To determine these barriers and facilitators, our research team partnered with Prisma Health-Upstate to interview healthcare professionals working at Carolina Cardiology Consultants--Greenville, which uses multiple RPM systems to monitor heart failure patients.

The twelve interviews conducted support that healthcare professionals would benefit from …

Triumph In The Suburbs: Richard Ford And The Spaces Of New Capitalism, John Gorton

All Theses

In his 1986 book America, Baudrillard noted that “the most banal suburb…is more at the centre of the world than any of the cultural manifestations of old Europe.” My thesis argues that this monumental shift from the suburbs as enclaves at the outer edges of cultural urban centers to “the centre of the world” is at the heart of Richard Ford’s realist project in his Pulitzer Prize winning Bascombe series starting with The Sportswriter in 1986. Emergent twentieth- and twenty-first-century literature scholars have been interested in the schism between the fictionalized representation and the lived experience of suburbia — while …

Examining The Perceptions Associated With Sunday Hunting Restrictions In South Carolina, Elizabeth Piller

All Theses

Public land is an invitation for many to engage with the natural world through a variety of different activities. Sometimes these activities are mutually exclusive and can cause land use conflict, which natural resource managers must navigate. One example of this conflict is restrictions to Sunday hunting. In South Carolina, Sunday hunting is allowed on private late but banned on public Wildlife Management Area (WMA) land. This regulation remains from ‘blue laws,’ laws prohibiting certain activities on Sundays to honor the Christian Sabbath (Balestra, 2008). Blue laws are typically thought of as prohibiting alcohol, but eleven U.S. states currently have …

Oam-Based Wavelets In A High Speed Optical Probing System For Measuring The Angular Decomposition Of The Environment, Justin Free

All Theses

This thesis presents the theoretical development of orbital angular momentum (OAM) based wavelets for the analysis of localized OAM information in space. An optical probing system for generating and detecting these wavelets is demonstrated; individual wavelets can scan the environment in 10µs or less. The probing system was applied to a three-dimensional atmospheric turbulence distribution to obtain a continuous wavelet transform of the angular information of the turbulent propagation path about a fixed radius. An entire continuous wavelet transform was measured in 3.8ms; the measurements are much faster than the turbulence and give insight into the short time scale of …

Feasibility Of Tracking Human Kinematics With Simultaneous Localization And Mapping (Slam), Sepehr Laal, Paul Vasilyev, Sean Pearson, Mateo Aboy, James Mcnames

Electrical and Computer Engineering Faculty Publications and Presentations

We evaluated a new wearable technology that fuses inertial sensors and cameras for tracking human kinematics. These devices use on-board simultaneous localization and mapping (SLAM) algorithms to localize the camera within the environment. Significance of this technology is in its potential to overcome many of the limitations of the other dominant technologies. Our results demonstrate this system often attains an estimated orientation error of less than 1^o and a position error of less than 4 cm as compared to a robotic arm. This demonstrates that SLAM’s accuracy is adequate for many practical applications for tracking human kinematics.

Scan4façade: Automated As-Is Façade Modeling Of Historic High-Rise Buildings Using Drones And Ai, Yuhan Jiang, Sisi Han, Yong Bai

Civil and Environmental Engineering Faculty Research and Publications

This paper presents an automated as-is façade modeling method for existing and historic high-rise buildings, named Scan4Façade. To begin with, a camera drone with a spiral path is employed to capture building exterior images, and photogrammetry is used to conduct three-dimensional (3D) reconstruction and create mesh models for the scanned building façades. High-resolution façade orthoimages are then generated from mesh models and pixelwise segmented by an artificial intelligence (AI) model named U-net. A combined data augmentation strategy, including random flipping, rotation, resizing, perspective transformation, and color adjustment, is proposed for model training with a limited number of labels. As …

The Role Of Investment Treaties And Investor–State Dispute Settlement (Isds) In Renewable Energy Investments, Ladan Mehranvar, Sunayana Sasmal

Columbia Center on Sustainable Investment

Achieving our global goals of universal access to clean energy and averting a climate crisis will require a mass scale-up of investments in renewable energy infrastructure, redirecting capital from carbon intensive energy and transport systems. The International Renewable Energy Agency estimates that the transformation of the energy system alone will need cumulative investments to reach USD 110 trillion by 2050 to keep the rise in global temperatures to well below 2°C and towards 1.5°C during this century. Of that amount, over 80% will need to be invested in renewables, energy efficiency, end-use electrification, and power grids and flexibility.

Conflicts Between Ghg Accounting Methodologies In The Steel Industry, John Biberman, Perrine Toledano, Baihui Lei, Max Lulavy, Rohini Ram Mohan

Columbia Center on Sustainable Investment

Accurate, verifiable, and comparable greenhouse gas (GHG) emissions data throughout supply chains in the materials sector are necessary to drive decarbonization. This is particularly the case for the steel supply chain, a major source of GHG emissions with untapped potential for reduction. However, emissions accounting methods used by the steel industry suffer from gaps and misalignment, resulting in significant differences in reported GHG emissions. The result is a patchwork reporting landscape vulnerable to manipulation and miscommunication, generating little actionable data for policymakers, producers, customers, and investors. These shortcomings highlight the need for a harmonized carbon accounting framework for the steel …

Creating A Better Browser Fingerprint, Scott Reiling

Interdisciplinary Informatics Theses, Dissertations, and Student Creative Activity

Web browser fingerprinting is used to analyze client behavior through retrieval of browser attributes unique to the user’s browser, network and hardware profile. Third-party trackers are prevalent on the top Alexa sites and use JavaScript to retrieve and store user machine information in a stateless fashion. Stateless fingerprinting is performed through acquisition of client machine specifiers through an embedded JavaScript, which then forwards the information to a server. The client information is purportedly used to provide tailored advertising and enhance the browsing experience. However, the depth of captured client information often extends into the realm of personally identifiable information. The …

Stimulus Discrimination Training And Its Effects On Generalization Gradients, Christopher Veenstra

Theses and Dissertations

Adaptation-level theory has been used to explain how the size and shape of generalization gradients depend on the procedure used to study generalization. However, most of the empirical support for this theory has come from studies using a relatively simple stimulus dimension (e.g., lights that vary in brightness). In addition, much of the research has focused on one specific prediction of adaptation-level theory: that responding during a generalization test should shift towards intermediate values within the tested portion of the stimulus dimension. The present research used a more complex set of stimuli. Specifically, the stimulus dimension was based on bar …

Possible Role Of The Storm-Generated Streamwise Vorticity In Tornado Intensification And Evolution, Lance Reed Wilson

Theses and Dissertations

Streamwise vorticity developing within the forward flank (FF) of supercell thunderstorms has been found to modulate the intensity of the low-level mesocyclone. However, few studies have quantitatively investigated FF vorticity contributions to low-level mesocyclone intensity. This study investigates the relative contribution of streamwise vorticity within the FF to the low-level mesocyclone strength using two Cloud Model 1 simulations with 75 m horizontal grid spacing initialized with the 18Z Jackson, MS, special sounding from the environment that produced the 27 April 2011 Tuscaloosa tornado. Vorticity budgets were calculated along forward trajectories that enter the low-level mesocyclone. Trajectories traversing through the FF …

Investigating The Effect Of Perceived Social Support And Professional Support On The Ability To Persist As A Building Administrator In Arkansas, Jill Annette Larosa

Graduate Theses and Dissertations

Across the United States, our K-12 public schools have very low levels of principals persisting in their jobs. The national average for principal tenure is four years, and one out of every five principals in poverty districts leaves after one year (Levin et al., 2019). The tenure average of four years is a devastating statistic because, according to an investigation commissioned by the Wallace Foundation (Leithwood et al., 2011), it takes an average of five years with a new administrator for a school’s performance to rebound to the level of achievement that existed before the administration change. At the current …

Enhancing Human Schwann Cells Reparative Behavior Using Heparin/Collagen Layer-By-Layer Coatings, Luis Carlos Pinzon-Herrera

Graduate Theses and Dissertations

When a peripheral nerve injury (PNI) occurs, the gold standard for tissue regeneration is the use of autografts. However, due to the secondary effects produced by multiple surgeries involved in the removal and implantation of autografts for very small lesions, it is possible to replace them with the use of Nerve Guide Conduits (NGCs). However, NGCs are limited to short lesions (less than 1 cm). This limitation is caused by the absence of compounds in the extracellular matrix (ECM) that autografts can provide. Since much of the regenerative process takes place on the NGC surface, our work aims to modify …
