Data-Driven Evalutation And Optimization Of Fishbone Well Configurations For Geothermal Energy Recovery In The Red River Formation, Cedar Creek Anticline, Candace Proksch

Theses and Dissertations

This thesis evaluates the geothermal potential of the Red River C interval at the Cedar Creek Anticline and develops a workflow for screening fishbone multilateral designs in a heterogeneous carbonate reservoir. Regional heat-flow and depth maps delineated Cedar Creek as a thermally favorable site and the lower dolomite as the primary reservoir target, supporting construction of a 3D Petrel model that captured the five-member C-interval architecture, petrophysical properties, and temperature field. A multi-stage Particle Swarm Optimization and fast-marching framework used this model to generate and rank fishbone injector–producer configurations, and a line-source approximation combined with a fixed-efficiency Organic Rankine Cycle …

Optimizing Virtual Reality User Experience With Balanced Integration Of Quality Attributes, Ananth Ramaseri

Theses and Dissertations

This dissertation presents a real-time adaptive framework for mitigating cybersickness and enhancing user experience in virtual reality (VR) environments by dynamically adjusting key visual rendering parameters in response to users’ head movements. Conventional VR systems typically rely on fixed or manually configured settings that do not account for individual motion patterns or varying susceptibility to discomfort, leading to suboptimal usability and degraded immersion. In response, this work integrates software architecture tactics with data-driven machine learning models to proactively manage cybersickness while preserving rendering performance.

The proposed system employs a client–server architecture based on the Model-View-Controller (MVC) pattern. We conducted a …

Impacts Of Intensifying Wildfires On Boreal Forest Ecosystems: Exploring Forest Regeneration, Wildlife Habitats, Carbon Storage, And Engineering Solutions, Mckenzie Belle Schewe

Theses and Dissertations

Wildfire activity across Alaska’s boreal forests has intensified in severity and frequency in recent decades, altering one of Earth’s most significant sources of carbon sequestration (Pan et al, 2011). This thesis examines how wildland burns influence post-fire carbon sink capacities and vegetation recovery near Fairbanks, Alaska. Three fire sites were selected to represent distinct successional stages: the 2006 Parks Highway Fire, the 2013 Stuart Creek 2 Fire, and the 2022 Clear Fire. Each site was evaluated through a combination of remote sensing analysis, LiDAR-derived canopy height data, and field measurements collected within each burn perimeter, developing a replicable framework for …

Exploratory Study Of Relationships Between Law Students' Well-Being, Academic Success, And Perceptions Of Passing The Bar Exam And Admission, Pamela Shea

Theses and Dissertations

This study explores the experiences of law students that impact their perception of being prepared for the Bar Exam and Bar admission. Analyzing the stressors law students face during law school reveals the essential need to incorporate the eight dimensions of well-being into curricular, co-curricular, and extra-curricular activities for students to flourish as they prepare for post-graduation success. Using the data from the 2021 Survey of Law Student Well-Being, which surveyed 5,865 law students from thirty-nine ABA-accredited law schools, a three-factor model was created to group students’ concerns into academic and health concerns, social and environmental concerns, and well-being behavioral …

The Impacts Of Hydrometeor Centrifuging On Numerical Simulations Of Supercells And Tornado-Like Vortices, Ronald Stenz

Theses and Dissertations

Supercell simulations capable of resolving a tornado-like vortex (TLV) have typically ignored hydrometeor centrifuging, resulting in the unrealistic buildup of precipitation in the center of TLVs. To improve the realism of numerical simulations of supercells and their resulting TLVs, an algorithm to parameterize bulk hydrometeor centrifuging was incorporated into an idealized cloud model. Simple idealized vortex simulations and simulations of supercells producing TLVs were analyzed to determine the impacts of hydrometeor centrifuging on numerically simulated supercells and TLVs. The inclusion of hydrometeor centrifuging does not appear to directly impact the intensity and duration of supercell spawned TLVs. Although precipitation minima …

Microbial Communities And Host Plants Of Megachilidae In The Greater Grand Forks Area (Ggfa), Sara Margit Wallace

Theses and Dissertations

Although Megachilidae are important pollinators in the United States, there is still much to learn about the health and functionality of these bees. Megachilids are threatened by competition from non-native pollinators and other environmental factors. The species distribution and composition of the gut microbiome in megachilid bees are not well known for the Greater Grand Forks Area (GGFA). My research seeks to answer the questions: what megachilid species are in the GGFA, where are they, and what symbionts are in their gut microbiomes? I collected and identified solitary bee specimens from North Dakota and Minnesota, dissected their gut contents, and …

Examining The Utility Of Haptic Feedback To Improve Pilot Situational Awareness & Performance: A Psychophysiological Approach, Jessica Van Bree

Theses and Dissertations

Pilot situational awareness (SA) has been deemed to be a critical component of flight efficacy, efficiency, and overall mission success. Studies have shown that several incidents and accidents have been the result of level-one SA errors, meaning that members of the flight crew have failed to accurately perceive the elements in their environments. As such, several strategies have been investigated to improve pilot SA. One potential avenue of research is the addition of haptics in to the flight deck. In some studies, the implementation of haptics have shown to improve piloting tasks, pilot safety, and aircraft control. The current study …

Experimental And Computational Insights Into Reservoir Rock Mechanics And Petrophysical Properties, Prasad Pothana

Theses and Dissertations

This dissertation investigates the influence of stress, mineralogy, and microstructure on the elastic and transport properties of reservoir rocks. A multi-scale framework integrating laboratory measurements, petrophysical inversion, and discrete-element simulations is developed to quantify the stress-dependent behavior of heterogeneous sedimentary formations relevant to hydrocarbon production and CO2 sequestration.

Core-scale experiments quantify velocity–effective stress and permeability–effective stress relationships in tight siliciclastic and mixed lithologies. Results demonstrate that pore-throat collapse and microcrack closure under confining stress cause systematic reductions in permeability and acoustic velocities. The derived empirical functions provide predictive capability for estimating in-situ stress effects on reservoir performance and time-lapse seismic …

Spatial–Temporal Evolution Of The Box Springs Plutonic Complex, Riverside, Ca, Mateo Ospino Díaz

Loma Linda University Electronic Theses, Dissertations & Projects

The mechanisms of pluton emplacement into continental crust have long been debated in igneous geology, with early models emphasizing forceful processes such as ballooning, later contrasted by alternative emplacement mechanisms including diapirism, incremental assembly, stoping and, emplacement by sheets and dikes. These contrasting perspectives highlight the complexity of the construction of mid-crustal intrusions and the need for case studies that integrate multiple datasets. The Box Springs Plutonic Complex (BSPC) in the northern Peninsular Ranges Batholith (PRB) preserves structural, textural, and compositional features that record its emplacement and internal construction. Although its lithology, structure, and geochemistry have been described, an integrated …

Breaking The Silence With Routine Genitourinary Syndrome Of Menopause Screening: A Quality Improvement Project, Ashley R. Noel

Electronic Theses and Dissertations 2020 - Present

Affecting upwards of 87% of women in post menopause, genitourinary syndrome of menopause is greatly under-diagnosed, and consequently, under-treated. Genitourinary syndrome of menopause refers to health conditions impacted by hypoestrogenic state experienced in menopause. Common symptoms of GSM include vaginal dryness, irritation, clitoral or labial atrophy, dyspareunia, decreased libido, anorgasmia, dysuria, recurrent UTI, urinary incontinence (Kaufman et al., 2025). Despite the burdensome consequences of GSM, women are unlikely to vocalize their symptoms and seek treatment. Additionally, societal beliefs of shame surrounding sexual health impede patients and clinicians from addressing GSM specifically (Mili et al., 2021). As a result, the North …

Enhancing Provider Knowledge And Implementation Of Medication For Opioid Use Disorder (Moud) To Improve Treatment Outcomes: A Quality Improvement Project., Motunrayo Abigael Ibraheem

Electronic Theses and Dissertations 2020 - Present

This quality improvement project sought to enhance healthcare providers' knowledge and attitudes toward Medication for Opioid Use Disorder (MOUD) at Galt Ocean Rehab Center to improve treatment outcomes for patients with opioid use disorder. Despite evidence supporting the efficacy of MOUD, significant knowledge gaps and stigmatizing attitudes among providers create barriers to optimal care. Sixteen healthcare providers participated in a comprehensive educational intervention grounded in Jean Watson's Theory of Transpersonal Caring and the Institute for Healthcare Improvement's Model for Improvement. The intervention consisted of a 4-hour workshop, six weekly reinforcement sessions, and the implementation of standardized buprenorphine management protocols. Pre- …

Enhancing Td Screening With The Aims Scale: A Quality Improvement Project, Dionne Smith

Electronic Theses and Dissertations 2020 - Present

Tardive dyskinesia (TD) is a persistent, often irreversible movement disorder associated with long-term use of dopamine receptor–blocking agents. Early identification is critical to prevent progression and minimize functional impairment; however, routine TD screening remains inconsistent in many clinical settings despite the availability of the Abnormal Involuntary Movement Scale (AIMS), the evidence-based gold-standard tool. This quality improvement project aimed to enhance TD screening in an outpatient psychiatric setting through an educational intervention designed to improve provider knowledge of risk factors, diagnostic criteria, and screening guidelines. Data were collected retrospectively and prospectively from patient encounters, with 33 pre-intervention and 35 post-interventions. AIMS …

Microfluidic Investigation Of Green Carbon Capture, Storage, And Utilization Using Waste Concrete And Seawater, Abhishek Ratanpara

Electronic Theses and Dissertations 2020 - Present

Carbon capture, utilization, and storage (CCUS) technology has emerged as a primary engineering pathway to mitigate global warming and climate instability. For carbon capture, amine-based absorption and stripping are widely used due to their high capture efficiency and retrofit compatibility. However, these systems generate toxic wastewater, consume large volumes of freshwater, and require significant regeneration energy. For carbon utilization and storage, deep saline aquifers and carbon dioxide (CO2)- assisted enhanced oil recovery (EOR) have been proven to be feasible options at the industrial scale; however, concerns remain about long-term subsurface storage integrity and limited efficiency in carbonate reservoirs containing more …

Teaching Firearms Law: One Big Opportunity And Three Pedagogical Challenges, Joseph Blocher, Jacob D. Charles, Darrell A.H. Miller

William & Mary Bill of Rights Journal

The U.S. Supreme Court’s groundbreaking 2008 decision in District of Columbia v. Heller ushered in a new era for the Second Amendment: one in which the right to keep and bear arms, long dormant as a matter of practical impact and even “embarrassing” as a matter of legal scholarship, vaulted into the front ranks of constitutional law. The Court itself has only revisited the Amendment a few times since then—albeit once by revolutionizing the doctrine. Meanwhile, lower courts have issued thousands of decisions giving shape to the right, while scholars have generated work that is increasingly deep, diverse, and challenging. …

Intellectual Integrity, Collaboration, And The Market, Mark Tushnet

William & Mary Bill of Rights Journal

My reflections are those of someone who co-edited/co-authored two casebooks that were commercially and intellectually successful and one that was intellectually but not commercially successful. I start with the assumption that people decide to do a casebook because they find that existing materials don’t do some things they think ought to be done in the course (and do some things that aren’t really necessary for teaching purposes). That is, doing a casebook is at the outset an intellectual project.

Executing that project runs up against some constraints almost immediately. A simple one is that you might well think that you …

Generational Impact: How U.S. Government Generative A.I. Use Reinvigorates Copyright-Based Takings Concerns, Sophia Tully

William & Mary Bill of Rights Journal

This Note argues (1) that the unique character of government copyright infringement supports a copyright holder’s use of the Takings Clause of the Fifth Amendment, as opposed to reliance on the Copyright Act for downstream Gen A.I. suits; (2) that Gen A.I. developers may wage similar claims once asserting authorship rights and copyright over their outputs; and (3) that the viability of federal government copyright infringement as a regulatory taking could change the way legal actors deal with copyrighted material. More modestly assessed, an answer on whether the Takings Clause protects copyrights would offer much needed guideposts as intellectual property …

Prostitution In Video Games: Stigma, Violence And Male Pleasure, Laura Aguilera-Ávila, Lara Escobar Hernández

Dignity: A Journal of Analysis of Exploitation and Violence

Prostitution has traditionally been framed in society as a space significantly determined by patriarchal hierarchies, in addition to being affected on many occasions by stigmatisation and violence. The representation of prostitution and of those who practice it in the media is a topic of special interest, since the discourses and messages disseminated by the media play a fundamental role in socialisation. Video games are not exempt from this debate: with millions of players worldwide and a special reach among young people, they are among the most influential media outlets today. This qualitative research analyses a series of titles, both AAA …

Exiting Commercial Sexual Exploitation, Jeanne L. Allert, Sherri L. Wyatt

Dignity: A Journal of Analysis of Exploitation and Violence

This study presents one of the largest qualitative samples of exited female survivors of commercial sexual exploitation in the United States to date. One hundred and eighty-nine female survivors participated in a national survey. The participants described their motivations for exiting commercial sexual exploitation, the pathways they followed, the forces that hindered their exit and increased their recidivism, and the assistance they received that ensured a permanent exit. Some of the findings challenge popular narratives on recidivism rates and what keeps women in exploitation, revealing complex relational, behavioral, economic, and systemic influences. Participants spoke about the unanticipated value of incarceration, …

Precision-Weighted Federated Learning, Jonatan Reyes, Lisa Di Jorio, Cecile Low-Kam, Marta Kersten-Oertel

Computer Science Faculty Publications

Federated learning (FL) using the federated averaging (FedAvg) algorithm has shown great advantages for large-scale applications that rely on collaborative learning, especially when the training data is either unbalanced or inaccessible due to privacy constraints. We hypothesize that FedAvg underestimates the full extent of heterogeneity of data when the aggregation is performed. We propose Precision-Weighted Federated Learning (PW) a novel algorithm that takes into account the second raw moment (uncentered variance) of the stochastic gradient when computing the weighted average of the parameters of independent models trained in a FL setting. With PW, we address the communication and statistical challenges …

Gradient-Based Model Shortcut Detection For Time Series Classification, Salomon Ibarra, Frida Cantu, Kaixiong Zhou, Li Zhang

Computer Science Faculty Publications

Deep learning models have attracted lots of research attention in time series classification (TSC) task in the past two decades. Recently, deep neural networks (DNN) have surpassed classical distance-based methods and achieved state-of-the-art performance. Despite their promising performance, deep neural networks (DNNs) have been shown to rely on spurious correlations present in the training data, which can hinder generalization. For instance, a model might incorrectly associate the presence of grass with the label "cat" if the training set have majority of cats lying in grassy backgrounds. However, the shortcut behavior of DNNs in time series remain under-explored. Most existing shortcut …

Nursing Students’ Attitudes Regarding Technical Standards For Entrance Into A Bachelor Of Science In Nursing Program, Jordyn Cook

Honors Theses

Admission into a Bachelor of Science in Nursing program requires students to meet specific criteria including a non-negotiable set of technical standards. Technical standards encompass physical abilities including twisting, bending, and handling objects of varying weights (Good Samaritan College of Nursing and Health Science, n.d.). While physical capabilities may hold significance in bedside nursing, the American Nurses Association does not establish specific physical qualifications (American Nurses Association, 2010). Due to admission criteria and technical standards, individuals with disabilities are rarely found among career nurses and nursing students (Leslie & Miller, 2020).

This study aims to determine nursing students’ attitudes towards …

Where Is Gender In The Historiography Of Lgbtq+ College Students?, Michael S. Hevel, Timothy Reese Cain

Counseling, Leadership, and Research Methods Faculty Publications and Presentations

This forum contribution considers the complexities and importance of gender in the historiography of LGBTQ+ college students. After a brief introduction, we focus on four key areas in the existing historiography: women's romantic relationships in the late nineteenth and early twentieth centuries, higher education leaders' enforcement of gender norms and purges of LGBTQ+ students through the mid-twentieth century, the gender dynamics within LGBTQ+ student organizations from the 1970s onward, and trans and other LGBTQ+ students' expansion of gender possibilities, including through the use of drag. In so doing, we argue that gender analysis is important to the historiography of LGBTQ+ …

The Influence Of Task Type And Learner Language Background On Writing Production And Anxiety: A Bayesian Linear Mixed-Effects Analysis, Mahmoud Abdi Tabari, Xinya Liang, Agnes Albert

Counseling, Leadership, and Research Methods Faculty Publications and Presentations

Despite growing interest in task-based language teaching (TBLT), limited empirical work has examined how different rhetorical task types influence second language (L2) writing development, especially in relation to affective variables, such as writing anxiety. Existing research in TBLT has largely focused on cognitive dimensions, often neglecting individual differences in learners' emotional responses. Moreover, Long's (2014) call to use first language (L1) data as a benchmark in TBLT remains underexplored, complicating the interpretation of L2 performance patterns. To address these gaps, we examined the impact of task type and writing anxiety on the written performance of 140 university students (70 L1 …

Real-Time Estimated Sequential Organ Failure Assessment (Sofa) Score With Intervals: Improved Risk Monitoring With Estimated Uncertainty In Health Condition For Patients In Intensive Care Units, Yan He, Qian Luo, Hai Wang, Zhichao Zheng, Haidong Luo, Oon Cheong Ooi

Research Collection Lee Kong Chian School Of Business

Purpose: Real-time risk monitoring is critical but challenging in intensive care units (ICUs) due to the lack of real-time updates for most clinical variables. Although real-time predictions have been integrated into various risk-scoring systems to aid monitoring, existing systems do not address uncertainties in risk assessments. We developed an enhanced risk monitoring framework based on commonly used systems like the Sequential Organ Failure Assessment (SOFA) score by incorporating uncertainties to improve the effectiveness of real-time risk monitoring in ICUs.Methods: This study included 5,351 patients admitted to the Cardiothoracic ICU in the National University Hospital in Singapore. We developed machine learning …

On Variations Of Isolation In Graphs, Geoffrey Boyer

All Dissertations

In 2015, Caro and Hansberg introduced a wonderful and natural generalization of the well-studied parameter of domination in graphs. For a graph $G$ and a family of graphs $\FF$, they define $S$ to be an $\FF$-isolating set if $G-N[S]$ contains no member of $\FF$ as a subgraph. The case where $\FF=\{K_1\}$ coincides with domination. The case where $\FF=\{K_2\}$ is now simply referred to as an isolating set. We strengthen known results about the isolation number of a graph, and explore variations of the parameter including the independent and total versions.

In particular for connected graphs of order $n$, a bound …

Navigating Safety: A Mixed-Methods Examination Of Supportive Workplace Practices In Maritime Contexts, Rebecca N. Pool

All Dissertations

Maritime Sailors operate in high-demand and high-risk environments that require sustained adherence to strict safety standards. Using the Conservation of Resources theory (COR), this dissertation examines how supportive workplace practices impact job stress and foster increased safety compliance among U.S. Navy personnel. Using a mixed-methods design, two studies were conducted with data from the Afloat Safety Climate Assessment Survey (ASCAS). Study 1 analyzed quantitative survey responses from active-duty Sailors (N = 15,517) nested in 1,033 departments nested within 122 ships to test a multilevel moderated mediation model linking social support, job stress, psychological safety, and safety compliance. Results indicated …

Exploring Halogen Bonding Interactions In Cocrystals And Deep Eutectic Solvents, Madhushi Bandara

All Dissertations

Halogen bonding is a noncovalent intermolecular interaction analogous to hydrogen bonding that occurs between an electrophile and a nucleophile. This is often observed in compounds containing heavy halogens such as iodine and bromine. When these halogens are covalently bonded to another atom or molecule, preferably to an electron-withdrawing moiety, an electrophilic region called a sigma hole is created on the halogen atom on the extension of the covalent bond.

The first study of this dissertation presents a comprehensive characterization of eight newly synthesized triiodide salts using single-crystal X-ray diffraction, powder X-ray diffraction, thermal analysis (DSC and TGA), and Raman spectroscopy. …
