Development Of A Model To Estimate Engine Crankcase Methane Vent Emission Rates, Juan Pablo Rincon

Graduate Theses, Dissertations, and Problem Reports (ETD)

The primary focus of this research is the modeling and validation of crankcase methane emissions stemming from natural gas combustion engines commonly deployed in the natural gas compression industry. The models employed rely on equations predicting the flow rate and composition of losses, typically generated within reciprocating piston-cylinder systems. Since crankcase emissions originate in a piston–cylinder arrangement, multiple variables were considered in this study, including displaced volume, pressure, temperature, flow, and viscosity (with corrections applied to account for the thermal and compositional effects on the mixture of fluids). The initial data for this research was collected during three measurement campaigns …

Trauma-Informed Yoga As An Adjunct To Treatment As Usual Within Inpatient Substance Use Disorder Treatment: A Feasibility Trial., Suzanne Vogler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Yoga interventions have been used more frequently in recent years within health and wellness settings to address both clinical and non-clinical issues. More specifically, yoga interventions and trauma-informed yoga (TIY) interventions are being explored within the treatment of substance use disorders (SUD). Initial research suggests that yoga interventions could be beneficial to the treatment of SUDs as an adjunct to treatment or a stand-alone intervention as part of continued recovery (post-clinical treatment) (Fitzgerald et al., 2021; Mallik et al., 2019). Although initial research is promising, the current quantity and quality of studies specifically exploring the feasibility and potential benefit of …

Modeling Relativistic Fluids In Dynamical Spacetimes, Terrence Alphonse Pierre Jacques

Graduate Theses, Dissertations, and Problem Reports (ETD)

Multi-messenger astrophysics opens a new era in our understanding of the most dynamic and energetic systems in the Universe. Correlating gravitational-wave and electromagnetic signals in space and time enables stringent tests of models for core-collapse supernovae, merging supermassive black-hole binaries with accretion disks and jets, and mergers of compact object binaries such as binary neutron stars (BNS) and white dwarfs. Comparisons between models and multi-messenger observations may be used to constrain the neutron-star equation of state (EOS), formation channels for compact-object binaries, and emission mechanisms behind short gamma-ray bursts.

In modeling such astrophysical systems, great success has been achieved by …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines the experiences and stories of two Black girls in predominantly White Appalachian communities, focusing on the language and literacy practices they employ to navigate and make sense of their Black feminine identities. It focuses on how literacy and language skills acquired from spending quality time with their mothers, engaging in various spaces with friends, and engaging in interest-driven traditional media and/or social media helped them to analyze their communities’ and the larger landscapes’ discourses around race and gender to create and modify their desired identities. This qualitative study employs narrative case study to center the lived experiences …

Watershed-Level Survey Of Antimicrobial Resistance From Onsite Wastewater Systems, Trey Franklin Clark

Graduate Theses, Dissertations, and Problem Reports (ETD)

The emergence of antimicrobial resistance (AMR) has quickly become one of the largest global health and development threats. Research related to environmental modes of transmission of AMR has accelerated in recent years, and the US Environmental Protection Agency is particularly interested in this emerging contaminant. Knowledge of how onsite (decentralized) wastewater treatment systems contribute to this issue is lacking, so this research serves to analyze and quantify the environmental dissemination of AMR and fecal contamination from these sources at a watershed level while using statistical analysis to assess relationships between physiochemical, spatial, and sampling parameters. This research surveyed four watersheds …

A Learning History Of A State Physical Activity Plan, Jessica Nicole Riffee

Graduate Theses, Dissertations, and Problem Reports (ETD)

Physical inactivity remains a persistent public health concern in the United States, disproportionately affecting rural populations like West Virginia. To address statewide physical activity challenges, West Virginia developed one of the nation’s first state level physical activity plans, ActiveWV: 2015, that was revised to ActiveWV: 2030. Limited research has investigated how statewide physical activity plans unfold over time or how stakeholder learning can drive improvement.

This dissertation employed a learning history action research methodology to construct a collective narrative of the development, dissemination, implementation, and evaluation activities across both iterations of the West Virginia Physical Activity Plan. Reflective interviews with …

Novel Phenomena In Chiral And Disordered Crystals, Zachary Louis Romestan

Graduate Theses, Dissertations, and Problem Reports (ETD)

The concept of symmetry is central to our understanding of the physical world. Core symmetries—comprising time reversal, charge conjugation, spatial inversion, and rotation—are integral in maintaining essential conservation laws. They also play a critical role in the manifestation of new quantum phases that arise when these symmetries are disrupted. At the heart of contemporary research in condensed matter physics is the exploration of how basic symmetries interact with material imperfections. This examination delves deeply into the ways that inherent symmetrical properties and structural anomalies within materials influence each other, providing crucial insights into the field. This dissertation presents an investigation …

Extinction Bursts Reexamined: The Role Of Consummatory Time And Response Reallocation, Braden Toler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Two experiments were conducted to examine how the removal of the opportunity to consume reinforcement and the reallocation of that time might account for extinction bursts during within-session transitions from FR 1 to extinction. In Experiment 1, rats and pigeons were trained under FR 1 schedules and subsequently exposed to within-session extinction. Total counts of responses suggested that extinction bursts occurred for each subject, but when adjusted to exclude responses that would have overlapped with food consumption, no bursts were observed. In Experiment 2, pigeons experienced four extinction arrangements: conventional extinction, response-independent reinforcement, conditioned reinforcement, and differential reinforcement of alternative …

Copula-Based Bayesian Model For Detecting Differential Gene Expression, Prasansha Liyanaarachchi, N. Rao Chaganty

Mathematics & Statistics Faculty Publications

Deoxyribonucleic acid, more commonly known as DNA, is a fundamental genetic material in all living organisms, containing thousands of genes, but only a subset exhibit differential expression and play a crucial role in diseases. Microarray technology has revolutionized the study of gene expression, with two primary types available for expression analysis: spotted cDNA arrays and oligonucleotide arrays. This research focuses on the statistical analysis of data from spotted cDNA microarrays. Numerous models have been developed to identify differentially expressed genes based on the red and green fluorescence intensities measured using these arrays. We propose a novel approach using a Gaussian …

In Search Of The Rational Voter In The 2020 Presidential Election: Understanding The Impact Of Voter Costs And Benefits On Turnout, Norou Diawara, Tiffany Henley, Samuel L. Brown, Md Iqbal Hossain

Mathematics & Statistics Faculty Publications

The ability to vote is one of the most valuable rights and privileges afforded by the Constitution of the United States to its citizens. For many, voting is not just a civic duty; it is also a choice. Voting is crucial to our democracy, and any changes to it may affect the efficiency of the democratic process. The bigger question is whether voters behave rationally by engaging in a cost-benefit calculus in deciding whether or not to vote. Using data science, this paper will examine the probability of voting and investigate its impact via cost and benefit among other variables …

A Bridge Too Low, John Adam

Mathematics & Statistics Faculty Publications

The article "A bridge too low" in the Physics Teacher journal discusses a low bridge near the River Greta in Keswick, England, with an arch shaped like a semiellipse. It presents questions about the maximum height a person of a certain height can walk under the bridge without hitting their head, the cross-sectional area of the arch, its eccentricity, and perimeter. The article also mentions the approximation by Indian mathematician Srinivasa Ramanujan for the perimeter of an ellipse and invites readers to find the answers online.

A Question Of Transparency: Solutions For Fermi Questions, March 2025, John Adam

Mathematics & Statistics Faculty Publications

Question 1: Why is it easier to see through rain than fog?

Start thinking about this by imagining a fixed volume (V) of water being dispersed into, say, N identical droplets of diameter d. Surface area and volume considerations should lead to the answer in terms of V and d.

Solution to Question 1: N = VI(πd³/6) = 6V/πd³ ≈ 2V/d³.

The cross-sectional area A of each drop is πd²/4 ≈ 3d²/4, so the total area blocked off (assuming no overlapping drops—so this is an upper bound) is NA ≈ 1.5V/d, so the area blocked off is inversely proportional to …

Public Constitutional Ai, Gilad Abiri

Georgia Law Review

We are increasingly subjected to the power of AI authorities. Machine learning models now underpin algorithmic markets, determine whose speech is amplified or restricted, shape government decisions ranging from resource allocation to predictive policing, and influence our access to information on critical issues such as voting and public health. As AI decisions become inescapable, entering domains such as healthcare, education, and law, we must confront a vital question: How can we ensure that AI systems, which increasingly regulate our lives and make decisions that shape our societies, have the authority and legitimacy necessary for effective governance?

To secure AI legitimacy, …

Surveillance As Retaliation, Daiquiri J. Steele

Georgia Law Review

Employers have a myriad of technologies at their disposal to help them surveil their employees, and they deploy these technologies for several reasons. Some of these reasons—e.g., monitoring time and attendance, ensuring compliance with occupational safety standards, protecting against certain data disclosure, etc.—are legitimate. Others are not. Chief among the illegitimate reasons is monitoring employees in retaliation for reporting alleged employer misconduct internally or externally. Just as terminating, demoting, or transferring an employee constitutes an adverse action for retaliation claims, subjecting an employee to surveillance because the employee has engaged in protected activity is also an adverse action. Courts and …

Protecting “Learned Hands”: Table Saw Injuries, The Sawstop Saga, And How Our Design Defect Doctrine Is Disincentivizing Safety, Tanner P. Samples

Georgia Law Review

The American judicial system has been grappling with the grisly realities of industrial carnage for over one hundred years. From Justice Cardozo’s storied expansion of manufacturer liability to the regulatory explosion of the 1960s, our nation has struggled to balance the personal freedom of consumers with the dangers of modern machinery. The winding morass of products liability law has afforded plaintiffs some degree of protection from the wily manufacturer, but most would agree that advancements in safety technology have prevented more consumer harm than any tort claim or cause of action.

Despite the unquestionable utility of safety advancements, analysis of …

On Parentage, Genetics, And Surrogacy, Jessica Tueller

Georgia Law Review

Bans in some jurisdictions, combined with relative affordability in others, have turned surrogacy into an increasingly cross-border phenomenon. Meanwhile, the complex and varied approaches to legal parentage and surrogacy that exist in domestic jurisdictions, along with a lack of international oversight, have at times left children of surrogacy parentless or stateless. The decision of the Hague Conference on Private International Law to begin regulating legal parentage in international surrogacy arrangements is thus an important and welcome development. However, the Hague Conference is considering imposing new genetic requirements that could result in violations of the rights to equality and non-discrimination of …

Jones V. Mississippi: Sweeping Away The Due Process Protections Of Juvenile Offenders, Tiffani N. Darden

Georgia Law Review

The U.S. Supreme Court’s pronouncement in Jones v. Mississippi raises questions about whether states will adequately adhere to the fundamental fairness principles of constitutional due process. The current juvenile sentencing procedures center on Miller v. Alabama, in which the Court struck down mandatory life-without-parole statutes applicable to juveniles. But in the post-Miller era, state legislatures and courts have struggled with how to apply the Miller Court’s holding. Ultimately, the Jones Court eliminated procedural due process rights for the criminal system’s most vulnerable class. But while procedural due process in the criminal sentencing context is not well defined as …

The New Game Theory, Cortelyou C. Kenney

Georgia Law Review

Game theory and the legal system it models are deeply indebted to the idea of efficiency and efficient outcomes. A great many scholars use game theory to rationalize approaches based on efficiency not only to commercial transactions but also to the legal system writ large, including the tort law system and the criminal justice system.

Efficiency and efficient outcomes have a storied history dating back to Vilfredo Pareto, Ronald Coase, and even before that to Adam Smith. But the person who truly popularized the idea of efficiency was John Nash, who won the Nobel Prize for his work on noncooperative …

Penneast Pipeline And The Policy Implications Of The Private Use Of Eminent Domain, Emily C. Wood

Georgia Law Review

This Note considers the modern implications of the takings power in light of PennEast Pipeline Co. v. New Jersey, a 2021 U.S. Supreme Court decision holding that states do not have the right to exercise state sovereign immunity against private parties holding congressionally delegated authority. Against current environmental conditions and recent takings power history, this Note then examines the delegation power of Congress and the public policy implications of the present administrative scheme—as compared to the typical exercise of the federal eminent domain power. Finally, this Note argues that the current administrative scheme ultimately removes important decisions impacting local …

Balancing Comity And Sovereignty: The Diplomatic Dance Of Antisuit Injunctions Against Foreign Sovereigns, Sean W. O'Halloran

Georgia Law Review

With the advent of globalization, sovereign nations both facilitate and participate in international transactions with public and private entities. As disputes inevitably arise, foreign sovereigns have increasingly found themselves as parties in U.S. courts, and in so doing, have raised fundamental questions as to the extent of a U.S. court’s power over a foreign sovereign.

For almost as long as the United States has been in existence, the doctrines of international comity and foreign sovereign immunity have served as guiding principles for U.S. foreign policy. Additionally, U.S. courts have long exercised their power to issue foreign antisuit injunctions—a vital tool …

Pluralism In State Constitutional Law, Michael L. Smith

Georgia Law Review

Debates over constitutional interpretation rage on—with most parties staking out preferred theories, their justifications, and assertions of their utility in predicting, explaining, and critiquing court opinions. The United States Constitution and the Supreme Court take center stage, despite a rich set of cases and constitutions at the state level. At the same time, state constitutional discussions tend to steer clear of federal interpretive theorizing.

This article seeks to bridge the gap between these literatures, arguing that state constitutional interpretation practices demonstrate a pluralist approach that may inform broader theoretical debates. State courts frequently employ different methods—sometimes explicitly, sometimes implicitly—both across …
