Multi-Commodity Flow Models For Logistic Operations Within A Contested Environment, Isabel Strinsky

All Theses

Today's military logistics officers face a difficult challenge, generating route plans for mass deployments within contested environments. The current method of generating route plans is inefficient and does not assess the vulnerability within supply networks and chains. There are few models within the current literature that provide risk-averse solutions for multi-commodity flow models. In this thesis, we discuss two models that have the potential to aid military planners in creating route plans that account for risk and uncertainty. The first model we introduce is a continuous time model with chance constraints. The second model is a two-stage discrete time model …

An Assessment Of Clemson Cooperative Extension Agents’ Perceptions Of Work-Related Factors Leading To Burnout, Erika Hwang

All Theses

Turnover and employee burnout are problems the Cooperative Extension System is facing nationwide, and the Clemson University Cooperative Extension System is no exception. There has been previous research done within the Extension system to identify the factors contributing to turnover and burnout, however, both remain an issue. Yet, there has been no research done to examine the Clemson University Cooperative Extension System individually. To further investigate factors contributing to burnout, this pilot study was conducted with Clemson University Clemson Extension agents using a burnout assessment that has not previously been used in Extension research. This study described Clemson University Cooperative …

Design And Fabrication Of An Optical Blade Tip Timing Sensor, Nick Tomlinson

All Theses

Electricity is a vital energy source that powers modern technology. Turbines are heavily relied on in the electric power industry for the conversion of natural energy sources into electricity. These turbines operate under harsh conditions which increase the likelihood of blade damage. Structural health monitoring of a turbine’s blades is important to detect problems before a blade experiences failure. The blade tip timing method can be used to monitor blade vibrations and determine if damage has occurred. An optical blade tip timing sensor is designed and fabricated to advance the field of sensing in the power industry.

Women Building After The Charleston Fire Of 1838 Using “An Act For Rebuilding The City Of Charleston” Loans, Joyce Pope

All Theses

The subject of this thesis is women commissioning buildings using loans they obtained as part of An Act for Rebuilding the City of Charleston. The Act, which passed after the fire of 1838, made $2 million dollars in loans available to all Charlestonians to rebuild the city after the fire wiped out hundreds of buildings on the peninsula. As a result of the way the act was structured, at least ten women, including a formerly enslaved woman, received loans and built houses and commercial buildings using those funds. This thesis examines whether the loan program opened the door for women …

Virtual Prototyping And Validation For Autonomous Assistive Mobility, Amogh Venkataramana Reddy

All Theses

Physical disability in humans is something that no one has control over. It is catastrophic for people to experience it, and sometimes hinders them from enjoying the essence of life. Though disability is something people have no control over, they do have control on how they can go forward and make life beautiful and meaningful. Wheelchairs have helped people with disabilities in mobility, allowing them to move around with the help of others or sometimes on their own. This research will focus on development of an autonomous assistive mobility robot to help the disabled using virtual prototyping tools for development …

Multiphysics Diesel Aftertreatment System Modeling For Reduced Emissions From Hybrid Electric Heavy-Duty Powertrains, Uday Srivastav

All Theses

Hybridization of heavy-duty on-road vehicles presents an opportunity to significantly reduce internal combustion engine emissions in real-world operation. These gains can be realized through the coordination of the electric drive, engine, and aftertreatment systems. Accurate Multiphysics models of all powertrains sub-systems are required to achieve the goal of reduced emissions. This research aims to develop a model of a highly complex diesel engine aftertreatment system. This study focuses on utilizing transient data for calibration and validation of the aftertreatment system and reducing the run time when compared to real-time experiments. The calibration focuses on two physical phenomena, thermal behavior and …

The Effect Of Deployment And Optimal Dispatch Of Shared Electric Shuttles On The Energy Efficiency Of Campus Transit, Robert Smith

All Theses

A problem facing most public transit systems is low energy efficiency and the continued cycling of large transport vehicles such as buses at low occupancy when low demand for transport exists, wasting energy to no benefit. To remedy this issue, we propose a hybrid system consisting of existing diesel buses and automated electric shuttles to augment the system during off-peak hours. Due to their smaller size, higher occupancy, and more efficient powertrains, these shuttles could reduce the system energy used per passenger-mile-traveled. Automation removes the labor cost of drivers and, thus, eliminates the need to employ more drivers for the …

Effects Of Ivd-Like Pressure And Ph On Human Adipose Derived Mesenchymal Stem Cells, Alexandria Pendino

All Theses

Low back pain (LBP) affects approximately 12% of adults in the US, and of these cases, between 26 and 42% are caused by intervertebral disc degeneration (IVDD). Current treatment approaches for LBP and IVDD, such as medication and surgery, mainly focus on reliving pain and do not address current or future degeneration. As a result of reherniation, up to 15% of patients will need a second surgery. As a solution, the use of tissue engineering combining scaffolds and stem cells to regenerate the damaged structures has been proposed. There are several types of stem cells that have shown potential for …

Influence Of Swirl And Turbulence In The Particle Removal Using Fog In A Pipe Flow, Nisarg T. Patel

All Theses

Fog-and-tube scrubbers are employed to remove harmful ultrafine aerosols, such as Diesel particulate matter (DPM), from an airflow. The underlying principle of this removal process involves enlarging the aerosol particles by coagulating them with fog drops, which are subsequently eliminated through inertial impaction onto the tube wall. Previous research conducted by Tabor et al. (2021) demonstrated an increase in scavenging of ultrafine DPM particles, ranging from 11.5 nm to 154 nm, by as large as 45% over the no fog case. This finding is crucial in addressing the challenges associated with conventional filtration methods for capturing ultrafine particles.

The present …

Performance Modeling Of Inline Compression With Software Caching For Reducing The Memory Footprint In Pysdc, Sansriti Ranjan

All Theses

Modern HPC applications compute and analyze massive amounts of data. The data volume is growing faster than memory capabilities and storage improvements leading to performance bottlenecks. An example of this is pySDC, a framework for solving collocation problems iteratively using parallel-in-time methods. These methods require storing and exchanging 3D volume data for each parallel point in time. If a simulation consists of M parallel-in-time stages, where the full spatial problem has to be stored for the next iteration, the memory demand for a single state variable is M ×Nx ×Ny ×Nz per time-step. For an application simulation with many state …

Bringing Vanished Landscapes To The Surface: A Multi-Tool Approach To Unearthing Charleston's Walled City, Alexis Allen

All Theses

The early 18^th century historic fortification system that surrounded the urban town of Charleston has been a focus of excavations and historical research within the past two decades. However, while the outline of early Charleston’s walled city is hypothesized through the analysis of historic maps and plats, very few fortification locations have been visually confirmed. In order to determine their accuracy, this thesis georeferenced eleven historic maps and four plats to the modern landscape. As a result, possible locations of Charleston’s walled city were predicted. These were surveyed as test sites and remote sensing methods were employed that helped …

Dynamics And Steering Of A Vibration-Driven Bristle Bot In A Pipe System, Ian Stewart

All Theses

Soft vibrational robots are robots that incorporate compliant structures into their design and are driven by oscillating actuators. A recent, popular version of a soft vibrational robot is the bristle bot, which uses flexible bristles and a vibration motor to propel itself across surfaces and through pipes. This motion is primarily driven by stick-slip dynamics resulting from asymmetric frictional forces applied at the bristle tips. Depending on the frequency of vibration of the motor, the robot experiences various resonance regions allowing it to maneuver in different directions. Attaching bristles to all sides of the robot and placing it in a …

Assessment Of Knee Flexion In Young Children With Prosthetic Knee Components Using Dynamic Time Warping, Mark Daniel Geil, Zahra Safaeepour

Faculty Articles

Introduction: Analysis of human locomotion is challenged by limitations in traditional numerical and statistical methods as applied to continuous timeseries data. This challenge particularly affects understanding of how close limb prostheses are to mimicking anatomical motion. This study was the first to apply a technique called Dynamic Time Warping to measure the biomimesis of prosthetic knee motion in young children and addressed the following research questions: Is a combined dynamic time warping/root mean square analysis feasible for analyzing pediatric lower limb kinematics? When provided at an earlier age than traditional protocols dictate, can children with limb loss utilize an articulating …

Graft-Versus-Host Disease: Teaching Old Drugs New Tricks At Less Cost, Shatha Farhan, Shernan G. Holtan

Hematology/Oncology Articles

Graft-versus-host disease (GVHD) remains a major cause of morbidity and mortality after allogeneic stem cell transplantation (SCT). Currently, more patients can receive SCT. This is attributed to the use of reduced intensity regimens and the use of different GVHD prophylaxis that breaks the barrier of human leukocyte antigen, allowing an increase in the donor pool. Once an area with relatively few clinical trial options, there has been an increase in interest in GVHD prophylaxis and treatment, which has led to many US Food and Drug Administration (FDA) approvals. Although there is considerable excitement over novel therapies, many patients may not …

A Nested Semiparametric Method For Case-Control Study With Missingness, Ge Zhao, Yanyuan Ma, Jill Schnall Hasler, Scott Damrauer, Michael Levin, Jinbo Chen

Mathematics and Statistics Faculty Publications and Presentations

We propose a nested semiparametric model to analyze a case-control study where genuine case status is missing for some individuals. The concept of a noncase is introduced to allow for the imputation of the missing genuine cases. The odds ratio parameter of the genuine cases compared to controls is of interest. The imputation procedure predicts the probability of being a genuine case compared to a noncase semiparametrically in a dimension reduction fashion. This procedure is flexible, and vastly generalizes the existing methods. We establish the root-n asymptotic normality of the odds ratio parameter estimator. Our method yields stable odds ratio …

Offshore oil and gas operations are inherently hazardous to the environment, posing environmental risks and impacts throughout all stages of the operations: exploration, development, production, and decommissioning. Offshore decommissioning consists of the process of planning, funding, and implementing measures aimed at safely closing, repurposing, or removing the infrastructure and equipment used in the exploration and production of oil and gas in the marine environment, and at mitigating their impacts. It encompasses a series of activities, including the safe plugging and closure of wells, the removal of equipment and pipelines, the repurposing of platforms, the disposal of non-usable materials and potentially …

Leeland Jones And Claude Clapp: Case Studies Of Civil Rights In Western New York, Kaelynn Beckman

History Theses

The Civil Rights Movement, which occurred primarily in the 1950s and 1960s, aimed to acquire justice, equality, and an end to racism and discrimination against Black Americans. In an attempt to do so, Black activists staged protests, walkouts, and boycotts and turned to institutions of education and politics to usher in change. However, the historiography on the Civil Rights Movement focuses on the more prominent events and individuals of the time, for example, Martin Luther King Jr., Rosa Parks, the Civil Rights Act of 1964, and the Voting Rights Act of 1965. The missing components of the historiography include the …

A Unit-Load Approach For Reliability-Based Design Optimization Of Linear Structures Under Random Loads And Boundary Conditions, Robert James Haupin, Gene Jean-Win Hou

Mechanical & Aerospace Engineering Faculty Publications

The low order Taylor’s series expansion was employed in this study to estimate the reliability indices of the failure criteria for reliability-based design optimization of a linear static structure subjected to random loads and boundary conditions. By taking the advantage of the linear superposition principle, only a few analyses of the structure subjected to unit-loads are needed through the entire optimization process to produce acceptable results. Two structural examples are presented in this study to illustrate the effectiveness of the proposed approach for reliability-based design optimization: one deals with a truss structure subjected to random multiple point constraints, and the …

Reduced Growth Mindset As A Mechanism Linking Childhood Trauma With Academic Performance And Internalizing Psychopathology, Lucy A. Lurie, Emily J. Hangen, Maya L. Rosen, Robert Crosnoe, Katie A. Mclaughlin

Neuroscience: Faculty Publications

Background

Despite the high prevalence of childhood adversity and well-documented associations with poor academic achievement and psychopathology, effective, scalable interventions remain largely unavailable. Existing interventions targeting growth mindset—the belief that personal characteristics are malleable—have been shown to improve academic achievement and symptoms of psychopathology in youth.

Objective

The present study examines growth mindset as a potential modifiable mechanism underlying the associations of two dimensions of childhood adversity—threat and deprivation—with academic achievement and internalizing psychopathology. Participants and setting Participants were 408 youth aged 10–18 years drawn from one timepoint of two longitudinal studies of community-based samples recruited to have diverse experiences …

Approximate Entropy And Velocity Of Center Of Pressure To Determine Postural Stability: A Pilot Study, Natalie Tipton, Gordon Alderink, Samhita Rhodes

Open Access Publishing Support Funded Articles

The body’s postural control system is responsible for responding to perturbations of balance and keeping the body upright. During quiet standing, the center of pressure oscillates about the center of mass, counteracting imbalances. These oscillations can be analyzed to determine the degree of stability, which could be helpful in quantifying the effects of brain injuries. In this research, the center of pressure was recorded for stances with feet together and feet tandem, with eyes opened and eyes closed, in neurotypical participants. These signals were analyzed using indices of approximate entropy and velocity to determine how sensitive the measures were in …

A Comparison Of Pm-Nato3’S Influence On Neural Progenitors And Mature Dopamine Neurons, Mary E. West

Masters Theses

This thesis presents significant findings regarding the role of PM-Nato3 in its interaction with developing neurons in the context of Parkinson's disease (PD) and regenerative medicine. We investigated the effects of PM-Nato3 on dopamine (DA) neurogenesis under different culture conditions, both in vitro and in vivo. In the standard dopaminergic culture condition, PM-Nato3 potentially increased the speed of DA neuron production but did not significantly increase the yield of DA neurons. In a minimal culture condition, there was no notable difference between the control and PM-Nato3 conditions, suggesting minimal impact on DA neurogenesis. In vivo studies using a mouse model …

A Calvinistic Divine Glory Defense, Stephen Thomas Irby

Graduate Theses and Dissertations

Calvinists, because they embrace the view that God ordains whatsoever comes to pass, cannot appeal to libertarian free will while trying to defend theism against the problem of evil. However, they can appeal – and, in fact, some have appealed – to God’s desire to be glorified to account for why He has ordained the evils of our world. This is the divine glory defense, and my dissertation aims to develop a version of it. After spending some time framing my defense in the context of the rest of the literature on the problem of evil, an account is provided …
