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 …

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 …

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 …

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 …

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 …

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 …

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, …

Through video and live garment scanning, users can access brand history, manufacturing information, condition assessments, marketplace price …

Evaluation Of Mechanical Properties And Seal Strength Of Medical Packaging Materials Before And After Supercritical Co₂ Sterilization, Camila Madriz Pizarro

Theses

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 …

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.

Radical Regionalism: Integrating Historical Vernacular Wisdom With Modern Building Science For Resilient Envelope Design, Barbara Patricia Montano

Theses

This thesis investigates how vernacular environmental knowledge can be integrated with contemporary building science to inform climate-responsive residential building-envelope design. In response to the limitations of standardized construction approaches across diverse climatic regions, the research proposes Radical Regionalism, a framework that combines vernacular environmental principles, passive design strategies, sustainable material selection, building-envelope science, and resilience considerations within a performance-based design methodology. A comparative climate-based modeling methodology is applied to a representative single-family residential prototype across four contrasting United States climatic contexts: Miami, Florida (hot-humid); Phoenix, Arizona (hot-dry); Boston, Massachusetts (cold-humid); and Denver, Colorado (cold-dry). Representative conventional code-minimum wall assemblies are …

Modeling Active Galactic Nuclei Spectra Of Supermassive To Hypermassive Black Holes, Priti Finavia

Theses

It is generally believed that most massive galaxies host supermassive black holes (SMBHs) at their centers, with masses ranging from 10^6 -10^{10} M☉. During phases of rapid accretion, these SMBHs emit electromagnetic radiation across the entire spectrum, resulting in luminous active galactic nuclei (AGN). An open question is whether SMBHs can grow to exceed 10^{10} M☉ through continued accretion and successive mergers, potentially forming hypermassive black holes (HMBHs).  The broad line region (BLR) consists of dense gas clouds located within sub-parsec distances of the central SMBH. The clouds are photoionized by continuum radiation emitted by the accretion disk and hot …

Puzzles & Frames: Exploring Motion Graphics In Thriller Movie Poster Design, Xingyu Xiao

Theses

This thesis explores how motion graphics can expand the role of traditional movie posters and create more engaging visual communication experiences. The project began with an observation that static posters displayed in busy campus environments can easily be overlooked. This led to the central question of how motion graphics can make traditional movie posters more visually engaging and effective in campus environments. To investigate this question, I developed a series of dynamic thriller movie posters that combine traditional graphic design elements—including typography, composition, imagery, abstraction, and visual hierarchy—with motion. The design process developed through several stages of experimentation. Early studies …

Beyond Conventional Construction A Sustainability Assessment Of 3d-Printed Concrete For Multi-Family Housing, Jennifer Candelier

Theses

The construction industry continues to face significant challenges, including labor shortages, increasing housing demand, rising material costs, and pressure to reduce environmental impacts. Three-dimensional printed concrete (3DPC) has emerged as a potential alternative to conventional construction methods by improving automation, material efficiency, and construction productivity. However, existing research has focused primarily on single-family applications, leaving limited understanding of its feasibility for multi-family residential construction. This study evaluates whether 3D printed concrete can become a standardized construction method for multi-family residential buildings by comparing it with conventional concrete masonry unit (CMU) construction. A comparative, performance-based methodology was developed using two equivalent …

Comparing Initial Data For Binary Neutron Star Mergers With Different Equations Of State, Aarati Nandre

Theses

Binary neutron star (BNS) mergers are an important tool for studying nuclear matter at extreme densities inaccessible to laboratory experiments. The equation of state (EOS) of this nuclear matter affects the inspiral dynamics, remnant properties, and the resulting gravitational-wave signal, but remains only weakly constrained at supranuclear densities. The observation of  GW170817 provided observational constraints on the EOS and established multimessenger astrophysics as a probe of dense matter. Simulating BNS mergers across a range of EOSs and comparing the resulting observables against detections helps narrowing this uncertainty further, and is the broader motivation for this thesis. General relativistic magnetohydrodynamic simulations …

Biochar-Derived Ethylene Scavengers For The Preservation Of Bananas, Morgan Samson

Theses

Ethylene regulates the rapid ripening of numerous climacteric fruits (e.g., banana, tomato, mango, and avocado). Minimization of ethylene formation and action in fruits during harvest or at any stage along the supply chain has become an important approach to prolong storage periods and minimize postharvest losses. Active packaging with ethylene scavengers has been proven to extend the shelf life of climacteric fruits; however, a cost-effective and sustainable solution is needed. Biochar-derived ethylene scavengers offer a promising approach to minimize postharvest losses, along with the valorization of abundant organic residues. This study produced and characterized biochars from two different feedstocks (i.e., …

Design Of A Continuum Robot Test Bed Utilizing Model-Free Sliding Mode Control, Joseph Paul Streib

Theses

Continuum robots are a class of continually deformable robots inspired by snakes and tentacles that are commonly used in medical, search and rescue, and exploration applications. The robots are highly nonlinear and difficult to accurately model and control. Precise control of the pose of a continuum robot is typically reliant upon a system model. This work introduces a novel model free control algorithm for continuum robots that only relies upon the robot’s position in task space. The derived controller is built upon the foundation of a preexisting model free sliding mode controller and the q-state parameterized piecewise constant curvature kinematic …

Capital Cities: The Intersection Of Power And Protest Urban Planning And Civic Design In Brasília And Washington, D.C., Noah Benjamin Gill

Theses

The physical environments of capital cities play a critical role in shaping how citizens interact with governmental power, particularly during moments of political unrest, protest, and democratic conflict. As both symbolic representations of national identity and functional centers of government, these urban landscapes influence how citizens approach, occupy, and confront civic institutions through their planning, architectural form, circulation networks, and spatial organization. Government buildings, public plazas, monumental landscapes, and civic axes do more than provide settings for political activity; they actively shape patterns of movement, visibility, accessibility, and control. The design of these spaces influences not only how democratic institutions …

Engineering Materials Function With Reconfigurable Colloids, Laura Galeano Tirado

Theses

The function of a material is defined not only by its chemical composition, but also by the structural organization of its constituents across multiple length scales, from the architecture of individual building blocks to their collective arrangement. Developing strategies to access, engineer, and reconfigure that structure on demand represents a central opportunity in the design of adaptive materials. Here, we present a thermoresponsive polymer-colloid platform that enables high-precision tuning of colloidal structures using only thermal stimuli. Rather than adsorbing to the surface, our polymers diffuse inside organosilica colloids to reshape them from within, allowing continuous modulation of their size, shape, …
