Evaluating A Dual-Beacon Hartmann Turbulence Profiling Technique Using Wave Optics Simulations, Benjamin C. Wilson, Matthew Kalensky, Santasri Bose-Pillai, Jack E. Mccrae Aug 2026

Evaluating A Dual-Beacon Hartmann Turbulence Profiling Technique Using Wave Optics Simulations, Benjamin C. Wilson, Matthew Kalensky, Santasri Bose-Pillai, Jack E. Mccrae

Faculty Publications

Resolving how optical turbulence varies along a propagation path remains a key challenge for designers of free-space optical propagation systems. Instruments such as scintillometers and differential image motion monitors are commonly used, but only provide path-integrated turbulence estimates. Point sensors provide localized estimates of turbulence strength and can be used to generate path-resolved profiles when an array of point sensors are distributed along the optical path. However, this approach can be costly and complex to deploy in certain environments. Alternatively, a single point sensor can be mounted on a mobile platform that collects data while traversing the optical path, although …

The concept of global citizenship can be traced back to the Greek and Roman periods in Western civilization, as well as to ancient Eastern philosophies. Representing both a prescriptive ideal and an aspirational faith in humanity, the notion is closely linked to the historical development of cosmopolitanism, transnationalism, and transnationality. This study first reviews the rich historical roots and core values of global citizenship, along with the growing need for global citizenship education in the modern era. It then highlights several influential individuals who strongly championed its principles, including theoretical physicist and Nobel Prize winner Albert Einstein and internationalist and …


Radio Frequency Resonate And Fire (Rf-Raf) Neurons Supporting Device Classification, David L. Weathers, Michael A. Temple, Brett J. Borghetti May 2026

Radio Frequency Resonate And Fire (Rf-Raf) Neurons Supporting Device Classification, David L. Weathers, Michael A. Temple, Brett J. Borghetti

Faculty Publications

Radio Frequency Fingerprinting (RFF) enables passive physical-layer device authentication by exploiting unintentional hardware variations in wireless transmitters. Neuromorphic implementations are attractive, given their potential for low-latency, energy-efficient inference capability under Size, Weight, and Power (SWaP) constraints at the edge. A new RFF capability is demonstrated here using recently introduced Radio Frequency Resonate-and-Fire (RF-RAF) neurons and eight WirelessHART devices. Performance is evaluated for RF-RAF-generated fingerprints against the established Gabor Transform (GTX) baseline using three classifier architectures: Random Forest (RndF), Convolutional Neural Network (CNN), and a Time-Incremented Spiking Neural Network (TI-SNN). The results show that RF-RAF fingerprints achieve an average classification accuracy …


The Judicial Voice On The Courts Of Appeals, Allison Orr Larsen, Neal Devins Jan 2026

The Judicial Voice On The Courts Of Appeals, Allison Orr Larsen, Neal Devins

Faculty Publications

The judicial voice on an appellate court typically speaks in the collective, so when a judge chooses to go solo—either in a dissent or a concurrence—that act deserves a close look. Separate opinions on the U.S. Supreme Court are common because the Justices have strong incentives to articulate a distinctive personal jurisprudence. But lower court judges have always been more reluctant to write separately, and for good reason. The institutional design and longstanding practices of the U.S. courts of appeals are very different from the Supreme Court: Lower appellate court judges are bound by precedent in a different way, rarely …

We examined global records of accessible natural history voucher collections (with publicly available data and reliable locality data) for terrestrial and freshwater vascular plants, fungi, freshwater fishes, birds, mammals, and herpetofauna (amphibians and reptiles) and highlight areas of the world that would be considered undersampled and sometimes called ‘unexplored’ (i.e., have relatively low, or no evidence of, past sampling efforts) under typical Western-scientific descriptions. We also question what ‘unexplored’ may mean in these contexts and explain how replacing the term in favor of more nuanced phrasing (e.g., ‘biodiversity blindspots,’ which emphasizes the lack of publicly available data about specimens) can …


The Art Belongs To The Artists, Deborah M. Weissman, Louis A. Pérez Jan 2025

The Art Belongs To The Artists, Deborah M. Weissman, Louis A. Pérez

Faculty Publications

This Article examines the rights of detainees interned at the Guantánamo Bay Naval Station to claim ownership of cultural work produced during their imprisonment. Through a series of arbitrary policies, the U.S. government alternately punished detainees for creating works of art, confiscated paintings and drawings, and otherwise denied detainees’ rights to control their creative works. This Article suggests the need to understand these policies as acts akin to plunder—that is, as a practice long associated with colonialism as a means through which the artifacts of the material culture of conquered peoples were expropriated and claimed as “trophies” of conquest. It …

Faculty Publications

This Article explores the relationship between the strategies of principled negotiation and effective persuasive legal writing as articulated in the best-selling books, Getting to Yes and Getting Past No. Though there is substantial scholarship advocating adding a negotiation component to legal writing instruction, there is little scholarship addressing how to apply the concepts of principled negotiation to persuasive writing itself. In this Article, the Author explains the foundational concepts of principled negotiation and then shows how they relate and apply to drafting an effective piece of persuasive legal writing. Looking at written advocacy through a negotiation lens reinforces good …


Understanding The Mechanisms Of Interpretative Change, Aaron-Andrew P. Bruhl Jan 2025

Understanding The Mechanisms Of Interpretative Change, Aaron-Andrew P. Bruhl

Faculty Publications

Interpretive methodology changes over time, and we appear to be in a period of particular ferment. In federal statutory interpretation, which is the focus of this Article, several important changes in interpretive methods have occurred in recent decades or are underway. There has been a gradual, decades-long shift away from intentionalist tools like legislative history. In addition, as the culmination of a series of smaller steps, the Supreme Court has just reshaped the doctrine governing deference to agency interpretations, a move that will require years of further clarification. And, although this shift is still taking shape, it appears that some …

An Account Of The 1453 Ce Ottoman Siege Of Constantinople Interpreted Through A First Century Bce Jewish Text: How An Ancient Collection Of Second Temple Period Poems Changed The Course Of Western Civilization, Kenneth Atkinson

Faculty Publications

On 29 May 1453 CE, the besieged Christian occupants of Constantinople — the capital of the Byzantine Empire and the last surviving portion of the former Roman Empire — knew the end was near when they heard 50,000-80,000 angry Ottoman soldiers, including 5,000 to 10,000 of the elite Janissaries — the Sultan’s shook troops — preparing to breach its walls after a 53-day siege. The 7,000-man army defending the city knew that all was lost. The 21-year-old Sultan Mehmet II — given the sobriquet “the Conqueror” for capturing the city — leveled the roads so his army could reach Constantinople’s …

Roman History In Sibylline Oracle 13: A Palestinian Jewish Perspective On Emperors, Usurpers, And Saviors During The Third Century Ce (Part Two: From Decius To Odenath Of Palmyra), Kenneth Atkinson

Faculty Publications

Sibylline Oracle 13 is a remarkable historical document that contains a unique perspective on the poorly documented period of Roman history known as the “Crisis of the Third Century (235-284 CE), which began with the assassination of the Roman emperor Severus Alexander (222-235 CE), the last ruler of the Severan dynasty. This turbulent era was marked by nearly fifty years of civil wars, barbarian invasions, rebellions, and approximately twenty-six claimants to the throne. Although the end of this turmoil under Diocletian (284-305 CE) is well known, we have little information about much of this century, particularly its first decades. The …

Strategies To Alleviate Flickering: Bayesian And Smoothing Methods For Deep Learning Classification In Video, Noah Miller, Glen Ryan Drumm, Lance Champagne, Bruce A. Cox, Trevor Bihl

Faculty Publications

Excerpt: Increasing reliance on autonomous systems requires confidence in the accuracies produced from computer vision classification algorithms. Computer vision (CV) for video classification provides phenomenal abilities, but it often suffers from “flickering” of results. Flickering occurs when the CV algorithm switches between declared classes over successive frames. Such behavior causes a loss of trust and confidence in their operations.


Limitations Of Beam-Control Compensation, Matthew Kalensky, Darren Getts, Matthias T. Banet, Derek J. Burrell, Milo W. Hyde, Mark F. Spencer Nov 2024

Limitations Of Beam-Control Compensation, Matthew Kalensky, Darren Getts, Matthias T. Banet, Derek J. Burrell, Milo W. Hyde, Mark F. Spencer

Faculty Publications

In this paper, we use wave-optics simulations to explore the limitations of beam-control compensation. We evaluate performance in terms of the normalized power in a diffraction-limited bucket for the cases of no beam-control compensation, perfect phase compensation, and perfect full-field compensation. From these results, we are able to arrive at the following conclusions: (1) without any form of beam-control compensation, performance begins to degrade when D/r0 > 1; (2) with perfect phase compensation, performance begins to degrade when D/r0 > 1 and (λ/r0)/θ0 > 1; and (3) with perfect full-field compensation, performance begins to degrade when D/r0 …

Production Box Cost Estimating Relationships For Dod Avionics, Carla J. Cisneros, Edward D. White, Brandon M. Lucas, Jonathan D. Ritschel, Robert D. Fass, Shawn M. Valentine

Faculty Publications

The authors use historical information obtained from the Cost Assessment Data Enterprise to estimate recurring production unit cost for DoD avionics via cost estimating relationships (CERs). The specific modeled responses include mean unit cost, median unit cost, and the 100th production unit cost (T100) utilizing learning curve theory. For T100, the authors adopt both a multiplicative and an additive error for CER comparison. Recommended CERs consist of the mean unit cost and the T100 utilizing a multiplicative error. Moreover, results reveal that weight has a significant effect on cost as well as a potential underaccounting of real price change or …

Magnetic Sensor Compensation Utilizing Factor Graph Estimation, Frederic W. Lathrop, Clark N. Taylor, Aaron Nielsen

Faculty Publications

Recently, there has been significant interest in the ability to navigate without GPS using the magnetic anomaly field of the Earth (magnav). One of the key technical bottlenecks to achieving magnav is obtaining an accurate magnetic sensor calibration, taking into account own-ship and sensor effects. The Tolles-Lawson magnetic calibration method continues to be the industry standard and was developed when airborne magnetic survey aircraft were first employed over 70 years ago. In this paper, we present a magnetic calibration algorithm based on a factor graph optimization using inertial measurements as well as inputs from both a vector and scalar magnetometer. …


Phase Error Scaling Law In Two-Wavelength Adaptive Optics, Milo W. Hyde Iv, Matthew Kalensky, Michael J. Spencer Jun 2024

Phase Error Scaling Law In Two-Wavelength Adaptive Optics, Milo W. Hyde Iv, Matthew Kalensky, Michael J. Spencer

Faculty Publications

We derive a simple, physical, closed-form expression for the optical-path difference (OPD) of a two-wavelength adaptive-optics (AO) system. Starting from Hogge and Butts’ classic OPD variance integral expression, we apply Mellin transform techniques to obtain series and asymptotic solutions to the integral. For realistic two-wavelength AO systems, the former converges slowly and has limited utility. The latter, on the other hand, is a simple formula in terms of the separation between the AO sensing (i.e., the beacon) and compensation (or observation) wavelengths. We validate this formula by comparing it to the OPD variances obtained from the aforementioned series and direct …

The results of first-step research activity are presented for realizing an envisioned “event radio” capability that mimics neuromorphic event-based camera processing. The energy efficiency of neuromorphic processing is orders of magnitude higher than traditional von Neumann-based processing and is realized through synergistic design of brain-inspired software and hardware computing elements. Relative to event-based cameras, the development of event-based hardware devices supporting Radio Frequency (RF) applications is severely lagging and considerable interest remains in obtaining neuromorphic efficiency through event-based RF signal processing. In the Operational Technology (OT) protection arena, this includes efficient software computing capability to provide reliable device classification. A …


Holding Aggressors Responsible For International Crimes: Implementing The Unequal Enforcement Doctrine, Nancy Amoury Combs Apr 2024

Holding Aggressors Responsible For International Crimes: Implementing The Unequal Enforcement Doctrine, Nancy Amoury Combs

Faculty Publications

It is a fundamental tenet of the laws of war that they apply equally to all parties to a conflict. For this reason, a party such as Russia — that illegally launches a war — benefits from all the same rights as a party such as Ukraine — that is forced to defend against the illegal aggression. Countless philosophers have shown that this so-called equal application doctrine is morally indefensible because defenders should have more rights and fewer responsibilities than aggressors. Legal scholars continue to support the equal application doctrine, however, because they reasonably fear that applying different rules to …
