The Myth Of Sufficient Technological Barriers: Reevaluating The "Gates-Up-Or-Down" Analogy In Data Scraping, Yucen Zhong

Duke Law & Technology Review

In Van Buren v. United States, the Supreme Court adopted a “gates-up-or-down” analogy from physical trespass law to define “authorization” under the Computer Fraud and Abuse Act (CFAA). Despite historical shifts in judicial interpretation, courts have recently relied on this binary framework to interpret authorization as it applies to online trespass. But courts have struggled to apply this binary inquiry while still accounting for complications in modern authentication technologies. When pursuing a code-based inquiry based on the gates-up-or-down analogy, courts risk oversimplifying the dynamic nature of online trespass. Such an approach fails to account for how modern authentication measures—such as …

Physics-Informed Neural Network Solution Of The 2d Helmholtz Equation With A Gaussian Source, Theodoros Panagiotakopoulos, Chris Velissaris, Aristotelis Nikolaos Rapsomanikis

Faculty Scholarship and Creative Works

We present a physics-informed neural network (PINN) framework for solving the complex-valued two-dimensional Helmholtz equation with a localized Gaussian source and spatially varying permittivity. Starting from Maxwell’s equations, the frequency-domain scalar Helmholtz formulation under transverse electric (TE) polarization is derived and enforced directly within the neural network loss function. The model employs a sinusoidal representation network (SIREN) architecture to capture the oscillatory nature of wave solutions and incorporates the Sommerfeld radiation condition to impose open boundary conditions. Training is performed using a hybrid collocation strategy combined with a two-stage optimization procedure consisting of Adam followed by L-BFGS. Numerical experiments in …

Female Indentured Servants And The Law In The Colonial Chesapeake, Jennifer Daniel Corbitt

Electronic Theses and Dissertations Archive

Abstract In colonial Virginia and Maryland, indentured servants were the primary engine of the colony's economy. In theory, the temporary exchange of labor for passage and potential social mobility offered women and men a similar opportunity to rise above their original station. However, the historical research of the past few decades has revealed that women had a distinctly different experience with the law than men. This thesis will argue that colonial law defined a particular and punitive form of servitude for white indentured women, viewing them as reproductive liabilities rather than as purely in economic assets. While The author has …

Faculty Publications

Components manufactured by Laser Powder Bed Fusion (LPBF) can incorporate particle dampers (PDS) by retaining unfused powder within internal pockets, providing inherent vibration suppression without added mass or separate damping components. This study investigates the damping performance of such LPBF-integrated PDs through two complementary approaches: (1) quantifying the effect of post-printing volume compression on energy absorption by mechanically indenting the damper pocket, and (2) evaluating how variations in particle packing density influence the dynamic response under both sinusoidal and transient impulse excitation. Experimental results from shaker and shock testing demonstrate that increased packing density, whether by compression or tighter confinement, …

Comparison Of Anomaly Detection Methods On Event-Based Vision Sensor Data In A High Noise Environment, Will Johnston, Anthony L. Franz, Shannon R. Young, Rachel Oliver, Zachary Theis, Brian Mcreynolds, Michael L. Dexter

Faculty Publications

Event-based vision sensors (EVSs) provide unique frequency analysis opportunities due to their event data output and high temporal resolution. Anomaly detection methods used in hyperspectral analysis can be used on the event frequency spectra to detect targets. However, the introduction of a strong, flickering interfering source can reduce the EVS sensitivity and obscure targets of interest. Previous work presented a method showing that targets could still be detected through an overwhelming source using frequency analysis, background suppression, and statistical filtering. This paper extends that research and compares the ability of five different eigenanalysis anomaly detection methods (principal component background suppression …
