Towards Accountability: A Primer On The Space Debris Problem And An Overview Of The Legal Issues Surrounding It, William Schonberg Jul 2025

Towards Accountability: A Primer On The Space Debris Problem And An Overview Of The Legal Issues Surrounding It, William Schonberg

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Since 1957, the near-Earth population of trackable space objects has grown in number to over 36,000. Of these 36,000+ trackable objects now in low Earth orbit, just a few thousand are working spacecraft. The rest are Earth-orbiting objects which are no longer operational and are considered to be space junk. Because this junk can no longer receive maneuvering commands from its Earth-based owners, the survivability of other spacecraft traveling through or operating in Earth orbit can be jeopardized by the impacts of any number of pieces of this space junk, whose origins can usually be traced back to defunct satellites. …


From Palimpsest To Prompt: Rewriting Shakespeare, Creative Authorship, And The Generative Logics Of Large Language Models In Contemporary Theatre, Michael Harding, James Hutson Jul 2025

From Palimpsest To Prompt: Rewriting Shakespeare, Creative Authorship, And The Generative Logics Of Large Language Models In Contemporary Theatre, Michael Harding, James Hutson

Faculty Scholarship

This article examines the convergence of creative authorship, adaptation, and generative artificial intelligence within contemporary theatre, taking Michael Harding‘s Awake, Young King as a central case study. Through the rewriting of Shakespearean drama, Harding‘s creative process demonstrates how theatrical meaning emerges through ongoing negotiation among playwright, performer, and audience, with scripts historically subject to revision, improvisation, and reinterpretation. Concerns regarding copyright, intellectual property, and the role of AI in the performing arts are reframed as extensions of enduring debates over originality and authorship, rather than novel threats. Tracing the evolution from The Rise of James VI to Awake, Young King, …

Monte Carlo simulations using FLUKA, conducted at Jefferson Lab, revealed that amongst Ni, Ti, Cr, and V, Ni exhibits the highest power dissipation, while Ti depicts the lowest power dissipation, with Cr and V demonstrating intermediate characteristics. Bulk polycrystalline (PC) and single-crystalline (SC) samples …


Unique Architecture: In Praise Of Paradox Persistence, Odaly Plancarte Jul 2025

Unique Architecture: In Praise Of Paradox Persistence, Odaly Plancarte

Theses

This thesis explores how bold and unconventional architectural designs are first rejected and later embraced by the public. Through a comparative study of the Sydney Opera House, the Louvre Pyramid, and the Walt Disney Concert Hall, it examines how public opinion shifts over time. Using media reports, interviews, and public comments, the study tracks emotional responses (positive, neutral, or negative) assigned a score to measure change over the years. The research applies Everett Rogers’ Diffusion of Innovation Theory to explain this shift in five stages: knowledge, persuasion, decision, implementation, and confirmation. Each building faced early backlash, but eventually became a …


Characterizing Tcap Set-Ups For Effective Separation On Hydrogen Isotope Species, James R. Hanby Jul 2025

Characterizing Tcap Set-Ups For Effective Separation On Hydrogen Isotope Species, James R. Hanby

Theses

Hydrogen isotope separation was investigated using a series of thermal cycling absorption process (TCAP) experiments. Pulse tests were conducted using deuterium injected into a protium flow over a range of superficial velocities, temperatures, particle sizes, and column diameters to quantify the efficiency of this process for a palladium on kieselguhr catalyst. The resulting response curves, obtained from residual gas analysis, were used to calculate the height equivalent to a theoretical plate (HETP) in each case. These values were then fit with van Deemter curves to illustrate the change in HETP over gas velocity. A strong positive correlation with temperature was …

Quantifying Marine Carbon Dioxide Removal Via Alkalinity Enhancement Across Circulation Regimes Using Ecco-Darwin And 1d Models, Kay Suselj, Dustin Carroll, Daniel Whitt, Bridget Samuels, Dimitris Menemenlis, Hong Zhang, Nate Beatty, Anna Savage

Faculty Research, Scholarly, and Creative Activity

Ocean Alkalinity Enhancement (OAE) is emerging as a viable method for removing anthropogenic (Formula presented.) emissions from the atmosphere to mitigate climate change. To achieve substantial carbon reductions, OAE would need to be deployed at scale across the global ocean. Hence, there is a need to quantify how the efficiency of OAE varies globally across a range of space-time scales in preparation for field deployments. Here we develop a marine carbon dioxide removal (mCDR) efficiency evaluation framework based on the data-assimilative ECCO-Darwin ocean biogeochemistry model, which separates and quantifies two key factors over seasonal to multi-annual timescales: (a) mCDR potential, …

The article explores Benjamin Ferencz's advocacy for international law and his role in shaping the legal frameworks of the post-World War II era, particularly his efforts to define aggression and establish the International Criminal Court. It contrasts Ferencz's idealism with the pragmatic approaches of Henry Kissinger and the diplomatic strategies of Dag Hammarskjold, highlighting the challenges of the Cold War international order and its failure to address individual threats, exemplified by A.Q. Khan's nuclear proliferation.


Secure Query On Encrypted Data By Using Fully Homomorphic Encryption, Mrinmoy Bera Jul 2025

Secure Query On Encrypted Data By Using Fully Homomorphic Encryption, Mrinmoy Bera

Master’s Dissertations

Cloud service providers typically store user data in an encrypted form (data at rest). However, when a user performs a query, the server first decrypts the data, processes the query on plaintext, and then sends the result back to the user (data in transit). This process exposes a critical vulnerability—if the cloud server is ever compromised, the decrypted data becomes accessible to the attacker. To address this security gap, we design a secure query protocol that eliminates the need to decrypt data on the server side. Fully Homomorphic Encryption (FHE) offers a groundbreaking solution by enabling arbitrary computations directly on …


Federated Learning Using Fully Homomorphic Encryption, Sk Golam Kuddus Jul 2025

Federated Learning Using Fully Homomorphic Encryption, Sk Golam Kuddus

Master’s Dissertations

Traditional machine learning approaches require centralizing data for training, which raises significant privacy concerns when dealing with sensitive information. Federated learning (FL) addresses this by keeping data local and enabling multiple users to collaboratively train a shared machine learning model. In spite of this, FL remains vulnerable to inference attacks, as sensitive information can still be extracted from the model’s learned parameters. While traditional privacy-enhancing techniques such as di!erential privacy introduce noise to model updates to obscure individual data points, they often present a fundamental trade-o! between privacy and utility. Furthermore, these approaches still carry risks of data leakage if …

The Impact Of Utilizing Injectable Platelet-Rich Fibrin And Collagen Plugs For Maintaining The Tooth Extraction Socket: A Review Study, Esraa Hameed Hassan, Ali H. Abbas Alhussaini

Al-Esraa University College Journal for Medical Sciences

Tooth extraction initiates a cascade of biological changes that result in alveolar bone resorption, compromising both the esthetic and functional outcomes of future dental rehabilitations, particularly implant placement. Socket preservation strategies have emerged as crucial interventions aimed at minimizing post-extraction ridge collapse. This review explores the synergistic effects of injectable platelet-rich fibrin (I-PRF) and collagen plugs in enhancing socket preservation outcomes. Collagen plugs serve as biocompatible scaffolds, promoting hemostasis, cellular migration, and angiogenesis, while supporting soft tissue healing and bone regeneration. Concurrently, I-PRF-an autologous, growth factor-rich biomaterial-provides a dynamic reservoir of platelets, leukocytes, and key cytokines such as Platelet-Derived Growth …

Modeling Multiple Tasks In Recommendation Systems, Dinh Hieu Do Jul 2025

Modeling Multiple Tasks In Recommendation Systems, Dinh Hieu Do

Dissertations and Theses Collection (Open Access)

Traditional research in recommendation systems has largely centered on the static offline supervised learning setting. In this paradigm, all available user-item interaction data is collected and partitioned into fixed training, validation, and test sets. Models are developed and evaluated in this controlled environment, where the underlying data distribution is assumed to remain unchanged. This approach offers clear advantages: it simplifies experimentation, enables reproducible benchmarking, and allows for straightforward comparisons between algorithms.

However, this static offline setting does not reflect the realities faced by modern recommendation systems. In real-world applications, data is dynamic and ever-evolving, where new users and items are …


From Sparse Feedback To Sequential Decision-Making: Learning Safety Constraints With Weak Supervision, Siow Meng Low Jul 2025

From Sparse Feedback To Sequential Decision-Making: Learning Safety Constraints With Weak Supervision, Siow Meng Low

Dissertations and Theses Collection (Open Access)

Real-world decision-making often involves safety constraints that are implicit, non-Markovian, or difficult to specify directly. Standard reinforcement learning (RL) approaches typically assume access to fully specified cost functions and constraint budgets—assumptions that limit their applicability in domains where such structure must instead be inferred from data. This dissertation develops a sequence of methods for learning safety-relevant structure from weak supervision, such as sparse binary feedback on trajectory segments, and using these signals to guide planning and policy optimization.

The first part of the dissertation introduces a sample-efficient method for planning in continuous Markov Decision Processes (MDPs) using deep reactive policies. …

The Buzzard In The Abolitionist Sea; An Examination Of Maritime Suppression, Imperial Policy, And The Slave Trade Through The Royal Navy’S Hms Buzzard, 1830s-1840s, Sean Joaquim Coudray-Pereira

Master's Theses

Analysis of the Royal Navy through the microhistory of the HMS Buzzard following the abolition of the slave trade between 1807 and the 1840s by Great Britain offers insight into the moral ambiguities and complexities of the humanitarian mission. The historiography of the slave trade has primarily focused on the moral and economic ideology behind its abolition, pitting one against the other. Applying a micro-historic approach highlights the nuances of both arguments, and through the HMS Buzzard’s crew, captives, disease, voyages, and legal battles accentuates the blend of both argument approaches. The case study of its longevity through all six …
