Advancing Cybersecurity Through Userland Memory Forensics: From Runtime Analysis To Security Applications, Hala Ali

Theses and Dissertations

Memory forensics has become a crucial component of digital investigations, particularly for detecting malware operating solely in system memory. As operating system vendors implemented kernel access restrictions, malware authors shifted to userland malware. However, existing memory forensics techniques have largely focused on kernel-level analysis, leaving userland runtimes insufficiently covered. This dissertation addresses this gap by expanding memory analysis capabilities across two distinct paradigms: interpreted and compiled runtimes. The first phase targets the Python runtime, developing automated recovery techniques that enable several security applications. For malware detection, these techniques extract critical forensic artifacts such as encryption keys and command-and-control configurations. For …

Proof Of Recovery: A Model To Enhance Data Integrity In Data Management Systems, Gustaf Barkstrom

Theses and Dissertations

Businesses lose millions of dollars every year when they can’t restore data from backups. Research shows that Disaster Recovery Plan (DRP) testing is not conducted frequently enough, nor are records maintained that demonstrate full data recovery from backups. This work introduces a design science artifact called PRTOK that aims to increase DRP testing. The design science artifact is a software solution that integrates with Data Management Systems (DMS)

such as iRODS and DSpace, and can work with formats such as HDF5 and BagIt. Proof-of- recovery records, or tokens, are recorded in a replicated, resilient, and indelible proof-of- authority blockchain data …

Nanomagnet Based Reservoir Computing And Quantum Control, Fahim F. Chowdhury

Theses and Dissertations

Conventional CMOS scaling has driven remarkable advances in computing but faces increasing physical and energy constraints, motivating alternative computing paradigms that integrate memory and computation while improving energy efficiency. Nanoscale magnetic systems offer a promising platform for such approaches because their intrinsic nonlinear dynamics and localized magnetic fields can support both classical and quantum information processing. This thesis investigates nanomagnetic systems for physical reservoir computing and, with primary emphasis, for localized quantum control of spin qubits.

The first part explores dipole-coupled nanomagnet arrays as physical reservoirs. Micromagnetic simulations demonstrate nonlinear dynamical behavior with high short-term memory and parity-check capacity, enabling …

Local Lung Delivery Of Ginkgetin For Therapeutic Intervention In Lung Fibrosis, Cimone L. Richardson

Theses and Dissertations

Lung fibrosis (LF) is a progressive, irreversible pathological condition in the lungs that is ultimately fatal. Current drug treatments (nintedanib, pirfenidone, and nerandomilast) slow disease progression but cause significant systemic adverse effects due to oral administration. Transient receptor potential vanilloid 4 (TRPV4), a mechanosensitive ion channel, may play a role in LF progression and represent a novel anti-LF target. Ginkgetin (GKT), a natural biflavonoid, is a potent TRPV4 inhibitor with anti-inflammatory and antioxidative properties. Local lung delivery could achieve high local lung concentrations while minimizing systemic exposure. Accordingly, this project evaluates GKT's therapeutic intervention efficacy in LF via local lung …

Managing Identity, Claiming Expertise, And Emotional Labor: A Constructivist Grounded Theory Of The Experience Of People With Serious Mental Illnesses In Primary Care, Jeffrey Ciak

Theses and Dissertations

People with serious mental illnesses (SMI) die 15 to 20 years before their peers without mental illness primarily due to chronic physical health conditions. Preventative care and treatment for chronic physical health conditions primarily occurs through primary care, but the experience of people with SMI in primary care is understudied. This constructivist grounded theory dissertation explored the experiences of people with SMI in primary care. Theoretical sampling resulted in 19 participants who were adults with SMI and long-term anti-psychotic use. Data was collected through one-to-two-hour long intensive interviews. The analytical process occurred concurrently with data collection. The abductive analytical process …

Modeling Of Laser-Produced Plasma Plumes: Expansion, Chemistry, And Thin-Film Deposition, Edmund Tsiri Semaha, Edmund Tsiri Semaha

Theses and Dissertations

Abstract

Laser-assisted material processing involves coupled plasma expansion, chemical reactions, and particle transport that govern the quality of thin-film deposition. This dissertation presents a comprehensive computational investigation of these processes using the OpenFOAM framework. First, the performance of the twoPhaseEulerFoam (tPEF), rhoCentralFoam (rCF), and sonicFoam (sF) solvers is evaluated for modeling laser-produced plasma plume expansion under atmospheric conditions, demonstrating that tPEF accurately captures shock-wave propagation, hydrodynamic behavior, and multispecies interactions. Building on this validation, the reactingFoam (rF) solver is employed to investigate the chemistry of aluminum plasma expanding into an air environment (Al–N₂–O₂). The model incorporates appropriate thermodynamic, transport, and …

Student Centered Approaches To Analyzing Engagement And Discourse, Kamil Hankour

Theses and Dissertations

Student engagement and participation in classroom discourse are widely recognized as powerful predictors of meaningful science learning, yet students’ own perspectives on the factors that shape their engagement and participation are currently underexamined. Prior research has established strong links between engagement, discourse and outcomes such as academic achievement (Bae & DeBusk-Lane, 2019; Fredricks et al., 2004; Sedova et al., 2019), but less is known about how students understand and interpret their experiences across individual, group-level and classroom contexts, particularly within historically marginalized populations (Cook-Sather, 2013; Schaefer et al., 2024). This three paper dissertation advances a line of inquiry integrating a …

Tangled Up In Blues, Clara B. Deweese

Theses and Dissertations

Martin Buber’s philosophy teaches us that when our masks fall and our armor’s unveiled, we discover humanity shared. Tangled Up in Blues unpacks the snapshot photographic practice I’ve had for years, which documents my mutually uplifting relationships, and is presented for my thesis exhibit through a painterly technique that deconstructs and reconstructs  the images onto wood panels using laser transfer. As we navigate a distracted and fragmented society made of greed and bigotry, cherishing the deep connections and shared memories brings us optimism.

Sensory Constellations, Madaline K. Gardner

Theses and Dissertations

This thesis situates neurodiversity within the field of fine arts by integrating disability studies, institutional critique, and material practices in painting and printmaking. Through visual analysis and studio-based research, the project examines how tactile engagement, color relationships, and repetitive mark-making can articulate embodied experiences of neurodivergence. It challenges dominant institutional frameworks that pathologize neurodivergent behaviors by reframing stimming as a generative and communicative practice. The resulting body of work includes both image-making and the creation of tactile objects designed to facilitate sensory interaction. The thesis proposes alternative ways of understanding artistic practice and accessibility within art institutions.

24-H Circadian Rest-Activity Rhythms And Physical Frailty In Older Adults: A Biopsychosocial Perspective On Sex Differences And Social Capital, Jisu Kim

Theses and Dissertations

Physical frailty is a prevalent geriatric syndrome characterized by age-related decline across multiple physiological systems. Physical frailty is associated with an elevated risk of adverse health outcomes, including chronic disease progression and all-cause mortality, representing a significant and growing public health concern. Disrupted circadian rest-activity rhythms (RARs) are increasingly recognized as clinically meaningful markers of physical frailty in older adults. However, the extent to which biological sex and social determinants of health (SDoH), particularly social capital, contribute to or modify the associations between RARs and physical frailty remains underexplored.

Therefore, this dissertation summarizes the existing literature on age-related changes in …

From Custody To Care: Understanding Mental Health And Recidivism In The Criminal Justice System, India Cox

UROP Posters

Previous studies on genetic influences in mental health disorders have been shown to correlate with incarceration rates in families. Consequently, there are individuals within the criminal justice system under the clinical threshold of a mental health diagnosis; it has been found that almost half of the incarcerated population was arrested due to acting upon their mental health disorder, while 27 to 38 percent developed PTSD while imprisoned. Furthermore, the serious and exhausting cycle of recidivism within the criminal justice system highlights the failure to provide the necessary mental health treatment required to support rehabilitation while incarcerated and prevent reoffending upon …

A Novel 3d Imaging Approach To Study Evolutionary Innovations In Solanaceae Inflorescences, Devin L. Jackson, Joonseog Kim, Wenheng Zhang Dr.

UROP Posters

Understanding the relatedness of angiosperms and the evolution of their inflorescence remains challenging, as these structures are highly modified and prone to convergent evolution. The current research describing inflorescence architecture, whether genetically or morphologically focused, typically relies on text based explanations, 2D images, or 3D based models created with CAD modeling software. This creates a disparity in the reader's understanding of these models since descriptions rely heavily on the author's interpretation of the inflorescence. The goal of our study is to bridge this disconnection by producing anatomically and color-correct 3D inflorescence models using Solanaceae flowers that readers can explore directly, …

East To West: Cultural Attitudes And The Perceptions Of Death, Hannah F. Ahmed

UROP Posters

Death is a universal human experience, but cultures teach people to interpret it in different ways. These interpretations influence how individuals understand dying, how they cope with loss, what support looks like, and what meaning death makes in their lives. Eastern, spiritual, and religious traditions emphasize death as a natural transition or return to divinity rather than an endpoint, and as something one must prepare for. In these contexts, people often grow up hearing stories, prayers, and teachings that situate death within a broader journey. Because of this, death becomes something familiar and speakable rather than distant or frightening (Naderi-Afif …

Land, Development, And Tribal Identity In India: The Heavy Engineering Corporation (Hec) And Tribal Land Acquisition, Nishka Malhotra, Anila Surin M.U.P., Niraj Verma Ph.D.

UROP Posters

Tribal land in Jharkhand, India, has been cultivated for generations by Adivasis, one of the largest aboriginal tribes of India. After India’s independence in 1947, the government-owned Heavy Engineering Corporation (HEC) was established as a tomb to the industrial development of a new India. Land for the massive project came from acquiring large tracts of Adivasi land. Even in cases where compensation was paid, the social and cultural costs borne by Adivasis far exceeded the land's market value. Our research (a) traces this history of how the discourse of modernization and development was used to justify dispossession of land; (b) …

The Importance Of Hippotherapy: Improving The Lives Of The Disabled Through Alternative Therapy, Jennifer N. Stapleton

UROP Posters

For centuries, horses have been suggested as “healers” and “helpers,” although it wasn’t until the 1900s that horseback riding was scientifically proven as a treatment and rehabilitation method. The exploitation of hippotherapy, the implementation of the three-dimensional pelvic movement stimulated by the oscillation and gait of the horse to combat symptoms of diseases and disorders, has since become a flourishing field of study, but one that is often overlooked. Benefits of hippotherapy often include increased motor neuron function, facilitating proper anatomical alignment, and reducing spasticity. This research analyzes the diverse and dynamic nature of treatment that hippotherapy facilitates, exploring the …

Establishing A Nonmedical Cannabis Market In Virginia: Implications For Equity, Craig Dearfield Phd, Anna Grace Causey, Rowan Baylosis, Nakeina E. Douglas-Glenn Phd

Research Institute for Social Equity

Virginia passed an adult-use (recreational; non-medical) cannabis law that went into effect on July 1, 2021. Allowing adult possession of cannabis requires the passage of laws and regulations that govern this market (often similar to tobacco or alcohol) due to the intoxicating nature of cannabis and to ensuring the safety of the production processes. Establishing a formal retail market can also address harms related to public health and criminal justice, and benefit state agencies and residents. In order to maximize benefits, Virginia must implement the market with an equity perspective to ensure just treatment for all residents and organizations.

Generating Synthetic Ct From Mri Data, Foysal Ahmed

Theses and Dissertations

Magnetic resonance imaging (MRI) provides excellent soft tissue contrast without ionizing radiation, making it a strong alternative to computed tomography (CT) in medical imaging workflows. However, CT remains essential for applications requiring electron density information, such as radiation therapy treatment planning. This study investigated the feasibility of generating synthetic CT (sCT) images from MRI using a deep learning-based U-Net architecture. A two-dimensional U-Net was trained on paired MRI-CT data from the SynthRAD 2025 dataset, consisting of 120 T1-weighted (T1W) and 60 T2-weighted (T2W) axial cases, including deformed CT (dCT) aligned to MRI.

Use Of Transcranial Magnetic Stimulation As An Assessment Of Corticospinal Excitability In Individuals With Persistent Postural Perceptual Dizziness, Elizabeth Cornforth

Theses and Dissertations

Persistent postural-perceptual dizziness (PPPD) is a common, disabling, chronic vestibular disorder whereby individuals experience symptoms of non-vertiginous dizziness, unsteadiness, and sway or rocking that are present most hours of the day, most days of the week. Individuals with PPPD have been noted to have an increased burden of dizziness and reduced quality of life compared to other dizziness diagnoses. The cause of PPPD is not well understood which can lead to years of diagnostic testing, failed therapies, and poor symptom management. It is important to understand PPPD pathophysiology so that optimal treatment interventions can be developed for this disorder to …

Walking And Wondering, Helen T. Tran

Theses and Dissertations

My thesis approaches walking as a form of inquiry and the Flood Wall as a site open to reinterpretation. I believe that the way we walk changes the way we observe and experience the world around us. This contrast between purposeful and leisurely walking reveals how time and intention shape our awareness of space. When walking is no longer dictated by urgency, it invites observations and questions. Slowing our pace allows curiosity to emerge, which aligns with my design ethos of asking questions as a foundation for understanding and creating meaningful experiences.

The Flood Wall’s emphasis on uninterrupted movement prioritizes …
