Rearchitecting Aerial Omniverse Digital Twin For Script-Driven And Scalable Simulations, Sarath Chandra Viswanadh Nagadevara

Computer Science and Engineering Theses - Archive

The Nvidia Aerial Omniverse Digital Twin (AODT) platform provides a comprehensive framework for modeling radio network behavior under varying user mobility scenarios for 5G, 6G, and beyond. However, the current AODT implementation relies on a graphical user interface (GUI) to manually configure simulation parameters and initiate runs, which limits its capability to support automated, large-scale simulations that are needed by future cellular networks. In this study, we re-architect AODT to enable automation and control through scripts by decoupling its original simulation backend engine from the GUI. We adopt a client-server architecture, where the server runs the simulation backend engine controlled …

A Deep Reinforcement Learning Framework For Sequential Art Creation, Asmin Pothula

Computer Science and Engineering Theses - Archive

Most computational art systems rely on generative models that produce a complete artwork in a single pass, without capturing the gradual, decision-driven process through which human artists construct visual pieces. Prior research in sequential, stroke-based image generation, including differentiable neural painters and model-based reinforcement learning agents, has explored step-by-step creation, but these systems typically aim to reconstruct the input image within the same visual representation space, closely matching brushstrokes, textures, or colors to the target. In contrast, this thesis investigates sequential art creation in a different artistic representation, where the final artwork does not share the same visual form as …

Crime Theory Informed Agent-Based Modeling For Crime Prediction And Patrolling Route Optimization, Shohreh Moradi

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Crime reduction remains a global priority, demanding both accurate modeling of criminal dynamics and efficient allocation of scarce policing resources. To address these needs, this study presents a two‐fold framework that (1) simulates street‐level crime patterns using an agent‐based model (ABM) grounded in Routine Activity Theory (RAT), Rational Choice Theory (RCT), and Crime Pattern Theory (CPT), and (2) optimizes patrol routing through a time-dependent, multi‐visit mixed‐integer linear programming (MILP) formulation.

In the first component, we integrate real‐world crime, environmental, and census data to reproduce realistic offender, citizen, and Police behaviors, capturing where and when robbery, burglary, and larceny occur across …

The situation is further exacerbated by the availability of advanced phishing kits, and more recently, generative AI, …

Synthesis And Application Of Cu-Based Ultrasmall Nanoparticles For Targeted Glioblastoma Treatment, Ryan T. Hart

Material Science and Engineering Dissertations - Archive

Glioblastoma (GBM) is a highly malignant form of brain cancer with a bleak prognosis. Current maximal treatment involves surgical resection followed by chemo-or radiotherapy. Two critical barriers make treating GBM a formidable challenge. First, the tumor's tendril-like proliferation throughout healthy brain tissue often makes complete surgical removal and conventional radiation insufficient. Second, the blood-brain barrier (BBB), which protects the brain, unfortunately also shields GBM from life-saving anti-cancer drugs. Here, we develop a radioactive nanoparticle-based therapy that directly confronts these limitations, offering a new strategy for GBM treatment.

Prostate-specific membrane antigen (PSMA) is a promising target for glioblastoma (GBM) treatment because …

There will be no explanation, only reputation.

Sky, the little g god, is in their forest on the first Halloween, scheming on how to ascend to Big G God status, will Sky be able to bop their way to the top, or will a fascist plot, accidental immaculate conception, and their hubris ruin the bitchin'est night of the year?

Navigating Compliance: How Wage Theft Influences Warn Act Decisions, Roberto Gonzales

Accounting Dissertations - Archive

Economic theory suggests that firms comply with regulations when the expected costs of noncompliance outweigh the expected benefits (Becker 1968). Despite minimal enforcement, weak penalties, and strong incentives for noncompliance, some firms comply with the provisions of the Worker Adjustment and Retraining Notification (WARN) Act, which mandates advance notice of mass layoffs and plant closings. Using a sample of 7,084 firm-years necessitating WARN Act disclosures from 2000 to 2020, I reassess the cost-benefit calculus by first demonstrating that wage theft violations provide the incentives necessary to compel firms to comply with other minimally enforced laws like WARN. Next, I find …

An Examination Of Donald Trump And Young Evangelical Voters, Kevin Finn

Honors Theses and Capstones

The relationship between Donald Trump and religious voters is often discussed, but much less attention has been directed to the connection between Trump and young voters, particularly young evangelicals. This paper attempts to provide the reasoning behind why despite his unconventional character, Trump maintains a strong base of support from young evangelical voters. After examining the theories of previous scholars, it hypothesizes that support is shaped by religious elites, who exploit the strong connection that young evangelicals have to their community. The argument is separated into three phases: first, that evangelical leaders and elites have proven to be consistently in …

Femicide Is A Human Rights Violation, Not A Cultural Consequence: Why Nigeria Is Violating The Maputo Protocol, Bolu Jegede

Human Rights Brief

Femicide, the most extreme form of gender-based violence, is the intentional killing of women simply because they are women. It is driven by harmful societal norms, such as oppressive gender roles, systemic discrimination towards women and girls, and gender power imbalances. Femicide is a universal problem but gaps in data on this issue mask the true scale of violence. For the first time since 2013, when the UNODC began publishing regional estimates, Africa surpassed Asia as the region with the highest number of victims.

Quota Reform, Repression, And The Fight For Human Rights In Bangladesh, Noreen Tareque

Human Rights Brief

On June 5, 2024, the High Court of Bangladesh ruled against the government’s decision to cancel the country’s quota system, stating that the decision to cancel the system in 2018 was invalid. This meant the country would go back to using the quota system to assign government jobs to students after they had completed their higher education. The quota system established that 30% of Bangladesh’s government jobs were reserved for the children and family members of freedom fighters who lost their lives during the Bangladesh Liberation War of 1971 against Pakistan.  Additionally, the quota system reserved 10% for women affected …

Photogrammetric Determination Of Movement Speed Of Invasive Indo-Pacific Lionfish In The Florida Keys, Neal Kolonay, Cassandra N. Glaspie

Faculty Publications

As a key determinant of how efficiently lionfish (Pterois sp.) locate and capture prey, swimming speed plays a crucial role in shaping the predator-prey interactions and broader ecological dynamics within the invaded ecosystems. Swimming speed on a small temporal and spatial scale is difficult to measure because of the need for precise measurements of both distance and duration of the behavior. Using photogrammetry by way of stereo-camera setups is ideal for analyzing the minutiae of lionfish behaviors because it can include the benefits of remote video traps coupled with precise measurements of movements in three-dimensional space and time. The primary …
