Training Safety Control Filters Using High-Dimensional And Un-Labeled Data, Yuxuan Yang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Synthesizing control policies that preserve the safety of autonomous systems is a challenge that remains to be solved. Towards that goal, control barrier functions (CBFs) have been developed as mathematical constructs that can be used in real-time to correct safety-violating nominal actions to ones which preserve the safety of control systems. However, synthesizing CBFs using correct-by-construction methods has not been scalable. Instead, recent research has proposed data-driven approaches for learning CBFs in the form of neural networks. Two main challenges face such approaches: (1) labeling states as unsafe or safe ones requires the knowledge of the states in the backward …

Transmutation, Sam Berger

MFA in Visual Art

My artistic practice is about change itself. I am inspired by the doubling and layering effects that came out of Surrealist Photography. Scale, fracture, and doubling are intentional components of my process. I combine those methods to create complex works of art, focusing on the untamable light that I hope to capture when making my images, which often are self portraits. Poetry is an integral element of this thesis text as well as my art making process. Through my poetic work I hope to offer my audience a glimpse into how I see and experience the world. This thesis text …

Digital And Physical Spaces: All At Once, Addyson Hoey

MFA in Visual Art

In this thesis, I explore our experience of digital and physical spaces in the ever-increasing presence of technology. By investigating the intersections of these spaces, I focus on how our experiences in the physical world are processed through the digital space, to re-merge in lived spaces. Through digital collage paintings, I explore how assisted chance and machine destruction can be productive in the formation of space that is not possible on the screen. By using the drop shadow as primary content, my work takes on the arrangements of surface and space—rather than the requirements of the physical world. In addition, …

Statistically Speaking...How Long Can The Next Pope Expect To Live?, Julian Stander, Mario Cortina-Borja

School of Engineering, Computing and Mathematics

We review our 2016 Bayesian survival analysis model prediction of the post-election survival time of Pope Francis, finding it to be accurate. We present a Lexis diagram showing the post-election survival times of popes from 1404. We use our model to make post-election survival time predictions for hypothetical popes aged 50, 60, 70 and 80 years. In the light of the election of Cardinal Prevost on 8th May 2025, we predict the post-election survival time of Pope Leo XIV. The advantage of our approach is that it yields the full survival time distribution, rather than just a point estimate.

Using A Pharmacokinetic Model To Design And Evaluate An Early Ctdna Biomarker For Response To Targeted Therapy, Aaron Li

Spora: A Journal of Biomathematics

Early prediction of response to therapy or lack thereof can help physicians plan treatment more efficiently. Biomarkers based on circulating tumor DNA (ctDNA) are promising. However, biomarkers beyond direct comparison to baseline have not been thoroughly explored. We develop a model for ctDNA shedding under targeted therapy that incorporates pharmacokinetics. Using a simulated cohort of virtual patients with varied parameters, we define and analyze a biomarker based on ctDNA samples at baseline, 12 hours, and 24 hours after initiation of treatment. The biomarker identified patients who would achieve partial or complete response with high sensitivity and specificity and was able …

Grafted Symbiosis: Strategically Revitalizing The Abandoned Atlanta Medical Arts Building Via Jeanne Gang’S Theory Of Grafting, Matthew Reddick

Bachelor of Architecture Theses - 5th Year

The Atlanta Medical Arts building, vacant for decades, stands at risk of demolition amid large-scale redevelopment efforts. Without an existing program to sustain it, how can we activate the site in a way that ensures both its immediate utility and long-term viability? This thesis explores a strategy for adaptive reuse, drawing from both parasitic architectural methodologies and Jeanne Gang’s concept of architectural grafting—while also critiquing the shortcomings of each approach. Rather than opting for a seamless integration, the design embraces disjunctive architecture by introducing a contemporary addition that is intentionally distinct from the historic Beaux-Arts shell, yet strategically …

How Extreme Rainfall And Failing Dams Unleashed The Derna Flood Disaster, Ayman Mokhtar Nemnem, Ahad Hasan Tanim, Audrika Nahian, Sadik Khan, Erfan Goharian, Jasim Imran

Faculty Publications

On September 11, 2023, Storm Daniel unleashed unprecedented rainfall over the Wadi Derna watershed, triggering one of the most devastating floods in modern history, striking Derna, a coastal city in Libya. This study reconstructs the disaster using an integrated modeling approach that combines satellite imagery, hydrologic, hydraulic, and geotechnical simulations, machine learning, eyewitness accounts, and digital elevation data to assess the impact of cascading dam failures. Our findings reveal that the region’s dams, even if structurally sound, would have provided minimal protection against the extreme runoff. However, their failure unleashed a destructive surge wave, amplifying the disaster’s magnitude and devastation. …

Performative Biomechanics : Evolving Buildings Into Inhabitable Organisms, Josh Lopez

Bachelor of Architecture Theses - 5th Year

There has always been a connection between biology and architecture. Michael Pawlyn, in Biomimicry in Architecture, coined “biomechanical designs” to describe structural techniques derived from creatures. This study investigates chitin-based creatures. Crustaceans, insects, and microscopic organisms all have exoskeletons in nature. With a focus on crabs, other crustaceans and bugs, this study examines and evaluates the formal characteristics of chitin-based organisms. The architectural creations of OXMAN, NOX, which was founded by Lars Spuybroek; and Lebbeus Woods are among those that are analyzed and studied due to their inspiration from living things. They follow functional effectiveness in nature, which is why …

On Appreciating Evidence, Auke Alesander Montesano Montessori

Arts & Sciences Graduate Student Theses and Dissertations

The topic of this dissertation is the kind of understanding or grasping necessary for successfully using something as evidence. I call this kind of grasp “appreciation”. Take the case of a fossil. Intuitively, you can only successfully use a fossil as evidence for the existence of dinosaurs if you appreciate the epistemic link between the fossil and dinosaurs. If you fail to grasp the relevance of the fossil and you think it is just a rock with a funny pattern, you would not be justified to form the belief that dinosaurs once existed based on that fossil. However, what it …

Chinese Students, Jim Crow Schools: Navigating Education In A Black-And-White Society, Amanda Young

Senior Honors Papers / Undergraduate Theses

Previous research on the history of education in the Jim Crow South has largely focused on the effects of legal segregation on Black communities. However, there existed another group: the Chinese. In the seemingly bifurcated system, their intermediate status was particularly discernible in the school. After Lum v. Rice (1927) stipulated that Chinese people, as members of the “colored” race, should be excluded from white schools, Chinese families sought other forms of education, including private tutors and church-sponsored mission schools. Still, they remained steadfast in their commitment to accessing white public education. The Chinese reproduced, acquiesced to, and in some …

Can You Hear Me Now? Student Perspectives Of 3d Phenomena-Based Science Teaching Practices, Leshea A. Moncrease

Dissertations

This dissertation presents findings of a self-study that investigated how student input, through reality pedagogy, may inform 3D phenomena-based teaching practices. 3D phenomena-based teaching practices are not new, but teachers are trying to determine how to use this framework to meet the needs of all students. 3D phenomena-based lessons use phenomena to drive instruction using core ideas, crosscutting concepts, and science and engineering practices. The goal of using 3D phenomena-based teaching practices is to create 21^st century critical thinkers and problem-solvers who engage in scientific habits. The acquisition of student perceptions through the analysis of student interviews, reflective journal …
