The Aesthetics Of Violation: Visual Rhetoric And The Ethics Of Spectatorship In Venetian Ovidian Painting, Khira Rudolph

Theses

In this thesis, we will consider how 16th-century Venetian painters used sophisticated visual methods, colorito, glowing atmospheric glazes, serpentine lines and spatial buffering to camouflage the physical violence of Ovidian abduction stories. Most historical art literature in the past has hailed high Renaissance masters Titian and Paolo Veronese as technical bravura, lyrical colorism and visual appeal in the face of social and emotional tragedy in their work on canvas. In comparing Titian’s The Rape of Europa, Paolo Veronese’s The Rape of Europa, Paolo Veronese’s circle Scene from the Metamorphoses of Ovid: The Rape of Proserpine and Rembrandt …

The St. Louis Zine Project: A Study And Documentation Of Live Music, Dawnye Appel

Theses

This practice-based project examines how documentary photography and zine-making can document and interpret an independent live-music venue as a site of atmosphere, cultural memory, and community. Focusing on The Sinkhole in St. Louis, Missouri, the inquiry considers what becomes visible when the venue, rather than only the performer, becomes the subject of photographic documentation. Project materials include photographs taken during a single visit on July 11, 2026, observations of the venue, and an interview with owner Matt Stutler, documented through written notes. Scholarship on live-music spaces, cultural memory, photography, and self publishing informs the interpretation of these materials. Analysis occurs …

Bayesian Network: An Explainable Artificial Intelligence (Xai) Approach To Human Performance Modelling For Control Room Operations, Houda Briwa

Theses

Alarm systems in process industry control rooms routinely exceed the performance targets set by standards such as EEMUA 191, placing operators under conditions where reliable performance is most difficult to achieve. Predicting how operators respond under such conditions is central to risk management, yet current Human Reliability Assessment (HRA) methods depend on expert judgement that is rarely tested against operational evidence, assume independence among factors known to interact, and do not explicitly represent the cognitive processes through which performance emerges. In Resilience Engineering terms, these methods encode Work-as-Imagined with limited means to assess how far expectations hold when work is …

Assessing The Impact Of Quantum Technology On Smart City Cyber Resilience, Afra Almansoori

Theses

Smart Cities rely on high-density digital infrastructures that include Internet of Things (IoT) devices, Artificial Intelligence (AI), cloud computing, digital identity systems, and operational technology. Although these systems improve efficiency and sustainability, they also provide a large cyber-physical attack surface. The problem is exacerbated by the advent of quantum computing, as popular public-key ciphers like RSA and elliptic-curve cryptography can be broken using quantum algorithms such as Shor's algorithm (Shor, 1994; Mosca, 2018). Smart cities rely on long-term data confidentiality, certificate-based trust, and remote management of critical infrastructure. This presents a strategic cyber resilience challenge. This thesis examines the impact …

Machine Learning Based Detection Of Unaccounted For Water Using Smart Water Meter Data, Uhoud Aljarman

Theses

The increasing deployment of smart water meters has transformed water distribution systems by enabling high-resolution, near real-time monitoring of customer level water consumption. In water scarce regions such as the Middle East and North Africa (MENA), and particularly in the United Arab Emirates (UAE) where potable water production relies predominantly on energy intensive desalination, these data streams present a critical opportunity to reduce Unaccounted-for Water (UFW), also referred to as Non-Revenue Water (NRW). UFW arising from physical leaks, meter malfunctions, unauthorized connections, and abnormal consumption patterns imposes significant economic, operational, and environmental burdens on water utilities (World Bank, 2016; World …

Predictive Modeling For Traffic Accident Severity Using Machine Learning, Ahmad Bin Eid

Theses

Road traffic accidents remain a persistent public safety challenge, responsible for over 1.3 million deaths annually according to the World Health Organization. While considerable effort has gone into understanding accident patterns, predicting the severity of an accident before or immediately after it occurs remains a difficult problem — particularly when the underlying data is messy, imbalanced, and largely categorical in nature. This study applies three supervised machine learning classification algorithms — Logistic Regression, Random Forest, and Gradient Boosting — to predict the severity of road traffic accidents using a dataset of 12,316 records collected by the Addis Ababa Sub-city Police …

Greennet: Ai-Driven Routing Simulator For Sustainable Internet Energy Optimization, Olta Zagraxha

Theses

Reducing the energy consumption of communication networks while maintaining reliable service is an important challenge in sustainable computing. This capstone presents GreenNet, a simulation and evaluation framework designed to investigate whether energy-aware network control can reduce estimated energy consumption without unacceptable degradation in Quality of Service (QoS). GreenNet combines a graph-based network simulator, configurable traffic scenarios, and a web-based interface for examining network behavior and comparing control strategies. Three approaches are evaluated: an All-On baseline that keeps all links active, a rule-based heuristic that selectively deactivates links, and a hybrid controller based on Proximal Policy Optimization (PPO), whose proposed actions …

Electromagnetic Signatures Of Massive Binary Black Hole Systems, Kaitlyn Porter

Theses

(EM) radiation, with their observable signatures shaped by the complex interplay between orbital dynamics, gas dynamics, and radiative processes. The evolution of the surrounding accretion flow is governed by general relativistic magnetohydrodynamics (GRMHD) within a strongly curved, timedependent spacetime, making the prediction of observable EM signals a challenging computational problem. This dissertation presents the development of a general relativistic ray-tracing framework that post-processes numerical relativity GRMHD simulations of accreting SMBHB systems. The framework enables the calculation of predicted images, spectra, and light curves throughout the inspiral, merger, and early post-merger phases. In parallel, improvements are made to an analytical model …

Zineth, Colin Wilcox

Theses

This thesis asks whether a brand can generate real engagement without surrendering to an algorithm, and whether web design can recover the color, mystery, and sense of discovery it traded away as the internet corporatized. Daily internet use has risen every year on record, yet the spaces users inhabit have flattened into grey buttons and endless feeds. This question is answered through Zineth, a hybrid brand universe told across three coordinated forms: a Risograph-printed zine, a dense and layered website, and limited clothing drops. The zine operates as a key. Codes printed in its pages unlock gated areas of the …

The Fate Of Microplastics In The Littoral Zone Of A Whole-Lake Microplastic Addition Experiment, Ren Staggs

Theses

Microplastics (MPs) are ubiquitous across all ecosystems, but the physical fate of MPs within specific littoral compartments in lakes is poorly understood. Here, we describe the fate of MPs across five littoral compartments: water, macrophytes, periphyton, rocks, and sediment, to contribute to a whole-lake MP particle budget as part of the pELAstic project, which has been adding polyethylene (PE), polystyrene (PS), and polyethylene terephthalate (PET) MPs to an entire lake over three years in a whole-ecosystem experiment at the IISD-ELA. We quantified MP abundance across three particle size fractions (>212, 106–212, and 106–53 µm) by sampling each compartment at …

Anxious Or Avoidant? The Moderating Effects Of Attachment Styles On Later Development Of Ptsd And Bpd In Individuals With Child Maltreatment History, Jeannette L. Burkle

Theses

Child maltreatment (CM) has been associated with the later development of borderline personality disorder (BPD) and Post-traumatic stress disorder (PTSD) among emerging adults. Numerous attachment studies have documented the association of insecure attachments with CM. There is little research on the independent effects of anxious and avoidant maternal attachment on later psychopathology and even less on the effects of peer attachment. Secure peer attachments can improve emotional regulation strategies as well as create healthy social support systems which may buffer against the development of later psychopathology. This study examined the independent effects of maternal and peer attachment in the relationship …

Navigating Errors: Voice Assistants And Aging Users, Bea Marithe V. Pulido

Theses

This study examined how age relates to usability, cognitive load, and affect when using voice-user interfaces (VUIs). VUIs such as Siri, Alexa, and Google Home are increasingly common and allow users to complete tasks through voice commands. While these systems can be convenient and accessible, especially for older adults, they often provide brief or unclear feedback when errors occur, making it difficult for users to understand what went wrong and how to continue the interaction. The current study compared older and younger adults (n = 40) to examine group differences in perceived usability, cognitive load, and affective change during VUI …

Metal-Assisted Chemical Etching For Heterogeneous Integration And Advanced Processing, Sami Znati

Theses

Emerging and existing technologies will require novel approaches to continue advances in development. Heterogeneous integration of next generation materials, such as 2-D materials and III-V semiconductors, onto existing platforms is a critical step to enabling new, better performing devices. Microtransfer printing (µTP) is a promising technique for integrating device coupons onto supportive platforms. InP coupons are integrated into mixed-dimensional structures by printing onto 2-D materials as part of an electronic device. Etching of next generation materials to define device structures is an integral part of any process. Catalytic wet etching is an alternative to dry etching that may offer improvements …

Accelerometer-Based Longitudinal Center Of Gravity Estimation With Lateral Acceleration Compensation, John Wynne

Theses

Spatially separated accelerometers and measured rotational motion can enable estimation of an aircraft’s longitudinal center-of-gravity (CG) location. Because the unrestricted rigid-body governing equations form an underdetermined system, the problem is reduced by assuming known lateral and vertical CG coordinates. The resulting estimator uses the lateral acceleration equation, where sensitivity to longitudinal CG is governed by the rotational excitation term 𝑀_21 = 𝑝𝑞 + 𝑟̇. Three representations of lateral acceleration at the CG are evaluated: a zero- acceleration assumption, a linear sideslip angle model, and a model based on sideslip angle and true airspeed squared. Each model is calibrated using known …

All The Pretty Ponies, David Rose

Theses

Adopting a nonconventional, narrative approach, this thesis explores a world of ponies where memories become distorted and rewritten through the author’s self-insert of a 'little pink pony' persona to illustrate the psychological states investigated in the exhibit. This paper serves as an artistic companion piece to the thesis exhibition by David Rose that featured these concepts through visual media. David utilizes painting, screenprinting, and animation as mediums for this body of work. This thesis is written like a story because David’s work is founded on the principle of creating and displaying an experience rather than simply stating the facts. Through …

Stochastic Inverse Problems In Stochastic Elliptic And Parabolic Pdes, Zi-Jia Gong

Theses

This dissertation presents a computational framework for solving stochastic inverse problems in partial differential equations (PDEs) with random data. The objective is to recover unknown random coefficients in parabolic and elliptic diffusion equations, as well as nearly incompressible linear elasticity models. To achieve this, optimization-based approaches are used to minimize regularized Energy Least Squares (ELS) and Output Least Squares (OLS) objective functionals. Both direct and adjoint methods are used to estimate the gradient and Hessian of the objective functionals with respect to the coefficients. To avoid the expensive computation of the full Hessian matrix, the Newton-CG-like method is also adopted, …

The sterilization of medical devices is critical in the prevention of infections in healthcare settings. Ethylene oxide (EtO), gamma irradiation, and steam sterilization have been the standard sterilization processes in healthcare settings, where the packaging system remains the most important barrier between the sterilized instrument/device. Safety concerns and regulatory pushback on conventional sterilization methods have pushed for further research on new sterilization techniques. Among the emerging sterilization technologies, one candidate that has garnered considerable attention is Supercritical CO2 sterilization. However, there is a lack of literature to support the compatibility between scCO2 and common medical packaging materials. The present study …

Investigations Into The Structure-Property Relationships Of Magnetic Fe2mnsn And Gradient Copt Thin Films For Next-Generation Magnetic Technologies, Lance Griswold

Theses

e study of spin-based electronic phenomena, or spintronics, has become increasingly important in materials science and condensed matter physics due to its potentialto enable next-generation magnetic technologies, including advanced memory devices and quantum computing. Central to this field is the relationship between a material’s atomic structure and its physical properties, which requires precise control over synthesis conditions to achieve desired magnetic and electronic behavior. In this work, I investigate the structure–property relationships of several magnetic thin-film systems, each designed to address a specific technological challenge. All films were synthesized using magnetron co-sputtering from elemental magnetic and non-magnetic targets, either at …

Measurement Of Kerr Rotation Using A Variable-Angle Polarizer Method, Shusmita Podder Pooza

Theses

The magneto-optical Kerr effect (MOKE) occurs when polarized light is reflected from a magnetized surface, causing changes in polarization angle (called Kerr rotation) and its state (linear vs elliptical, for example). In a simple version, MOKE measurement involves measuring the intensity of the reflected beam off the surface of a sample as an external magnetic field is swept through it. We record a change in the reflected intensity when the magnetization of the material changes. While easily measurable using modern electronics methods, the Kerr rotation is minimal, only of the order of milliradians (~0.1 deg), and is a characteristic of …

Design And Verification Of A Reconfigurable Cryptographic Hardware Accelerator, Nicholas Merante

Cryptographic operations are used throughout computing systems to protect data confidentiality and integrity. Although software implementations provide flexibility, dedicated hardware can offer more predictable execution time and reduce the processing burden placed on a general-purpose processor. This thesis presents the design and verification of a Reconfigurable Cryptographic Hardware Accelerator (RCHA) that integrates AES-128, ChaCha20, SHA-256, and BLAKE2s within a single Verilog/SystemVerilog design. A top-level interface shared by the four cores manages algorithm selection, inputs, outputs, status, protocol errors, cycle measurement, and known-answer self-tests. Verification combined primitive-level tests, integrated UVM regressions, randomized stimulus, directed coverage tests, and OpenSSL-based C++ reference models …

Poppies In Bloom: Gathering Galaxies From Jwst Parallel Fields, Anika Kumar

Theses

A major goal of extragalactic astrophysics is connecting the Big Bang to the present by under- standing the evolution of star formation (SF) across cosmic time. The correlation between SF and the stellar mass buildup in galaxies, or the star forming main sequence relation (SFMS), highlights the various mechanisms that drive galaxy evolution. Deviations like quiescent galaxies, which have ceased forming stars, and starburst galaxies, which undergo an exceptionally high rate of SF compared to their normal star formation histories (SFH), offer key clues to the catalysts of galaxy evolution (e.g., mergers, gas accretion, supernovae feedback). Our understanding of early …

Asynchronous Methods For Reducing Dynamic Power In Sparse Systems, Braley Lachner

Theses

While a strong history of computer development has maximized architecture performance, modern computing is fundamentally constrained by thermal limits and power consumption. This is especially true in power sensitive edge applications, which often have low activity. Asynchronous architectures offer a pathway to take advantage of sparsity within hardware to drastically reduce dynamic power through fine-grain selective activation of only necessary hardware. Despite these advantages, the semiconductor industry relies heavily on Electronic Design Automation (EDA) toolchains, which have been developed with many synchronous assumptions. The traditional overhead and strict incompatibility with standard EDA toolchains have limited adoption of asynchronous technologies in …

Effects Of Disorder On The Magnetic And Electronic Structure Of Kagome Alloy Fe2mnsn., Thayne Dean

Theses

Iron-based magnets with the Kagome lattice are a rich set of materials due to their non-trivial topology combined with high magnetic ordering temperature (Tc). Previously, we identified and synthesized Fe2MnSn as a promising material with high magnetic anisotropy characterized by a high Tc. The desirable magnetic properties of ternary alloys are controlled by atomic-level antisite disorder and are sensitive to stoichiometry as well. To illustrate the role of disorder in Fe2MnSn, we performed DFT calculations using 64-atom supercells, which enabled us to probe changes in the density of states and magnetic moments by design. Our data show that substitution of …

Radiometric Dating And Isotope Analysis To Determine The Source And Timing Of Rare Earth Element-Bearing Fluid Mineralization At Hicks Dome, Hardin County, Illinois, Kristina M. Kohl

Theses

The Hicks Dome structure of Hardin County, Illinois, located within the Illinois-Kentucky Fluorspar District (IKFD), is one of the most perplexing geological features in the mid-continental U.S. Composed of uplifted Devonian strata intruded by a Ca-rich magma and ultramafic dikes, the dome is recognized as part of the Wauboukigou Igneous Province (WIP) and has been shown to host an abundance of rare earth element (REE) mineralization, particularly Dy, Y, and Sc. Despite extensive prior studies on REE concentrations and the link between fluorite mineralization in the IKFD and igneous activity at Hicks Dome, the absolute timing and relationship among REE …

Combining Citizen Science And Machine Learning: The Blueprint For An Emission Line Detection Algorithm, Alex Kiely

Theses

Extragalactic spectroscopy provides us with information about the properties of galaxies and the fundamental nature of the universe. By analyzing galaxy spectra, we gain insight into a galaxy’s evolution through measures of its star formation rate (SFR), metallicity (Z), ionization parameter (U), gas pressure, dust extinction, electron density, and redshift (z). Redshift, in particular, can provide us with information about a galaxy’s velocity and distance, the formation of baryonic matter, dark matter halos, and the variation of galaxy properties with redshift. The analysis of these spectra is often an incredibly demanding, time-intensive, and potentially inaccurate process, further complicated by the …

Building A Multiwavelength Catalog Of Active Galactic Nuclei For The Cosmos Field, Thresa Kelly

Theses

Active galactic nuclei (AGNs) are capable of producing highly luminous emission across the entirety of the electromagnetic spectrum. Each waveband has characteristic features that can be used to separate AGNs from typical, inactive galaxies. However, each AGN has a unique combination of physical characteristics--such as the black hole mass, accretion rate, obscuring column density, orientation angle, and/or presence of relativistic jets--that create a unique spectral shape. Thus, a single AGN identification technique using a single wavelength will fail to find all types of AGNs. The resulting sample will bias the results of larger statistical studies. Therefore, it is critical to …

Analyzing The Effects Of Biodegradable Plastic Fragments On Maize Development And Defense Signaling, Ulysses Hampton

Theses

As plastic use shifts from non-degradable to biodegradable materials, the effects of biodegradable plastic fragments on crop physiology remain unclear. This study investigated how biodegradable plastic fragments influence maize development, transpiration, and defense signaling. Among five plastic types tested, poly(butylene adipate-co-terephthalate) (PBAT), polyhydroxyalkanoates (PHA), polycaprolactone (PCL), polylactic acid (PLA), and thermoplastic starch (TPS). PBAT and TPS showed the most significant effects and were selected for further oxylipin analysis. Results indicate that biodegradable plastic fragments can alter oxylipin signaling pathways in subtle but meaningful ways, suggesting that these materials are not inherently risk-free alternatives to conventional plastics.
