Drone Detection Using Yolov5, Burchan Aydin, Subroto Singha

Faculty Publications

The rapidly increasing number of drones in the national airspace, including those for recreational and commercial applications, has raised concerns regarding misuse. Autonomous drone detection systems offer a probable solution to overcoming the issue of potential drone misuse, such as drug smuggling, violating people’s privacy, etc. Detecting drones can be difficult, due to similar objects in the sky, such as airplanes and birds. In addition, automated drone detection systems need to be trained with ample amounts of data to provide high accuracy. Real-time detection is also necessary, but this requires highly configured devices such as a graphical processing unit (GPU). …

Plea Bargaining's Uncertainty Problem, Jeffrey Bellin

Faculty Publications

While commentators roundly condemn plea bargaining, the criticism can be as muddled as the practice itself. Critics’ primary target is the “trial penalty.” But a differential between guilty-plea and trial sentences seems inevitable in any system that allows defendants to concede guilt. And, as a new wave of “progressive prosecutors” is demonstrating, gaps between (unusually lenient) plea offers and long (potential) post-trial sentences are not only a strong incentive to plead guilty but also a powerful tool for reducing American penal severity. Other critiques point to flaws that parallel those found in the broader system, overlooking that plea bargaining is …

Reuben Lewis was born in 1777, the fourth and youngest child of William Lewis and Lucy Meriwether. Their oldest child, Jane, married and lived out her days at Locust Hill, the family estate in Virginia. The Lewis’ second child, baby Lucinda, died in infancy. Their third child, Meriwether – the closest in age and friendship to Reuben – became the famous first half of the Lewis and Clark Expedition which explored the uncharted West before he met his tragic and mysterious death on the Natchez Trace in Tennessee. While Reuben’s life has been rightly overshadowed by his older brother Meriwether’s …

Origami-Based Design Of Conceal-And-Reveal Systems, Bryce P. Defigueiredo, Kyler A. Tolman, Spencer P. Magleby, Nathan A. Pehrson, Erica Crampton, Larry L. Howell

Faculty Publications

This work introduces a type of motion termed “conceal-and-reveal” which is characterized by a state that protects a payload, a state that exposes the payload, and coupled motions between these two states. As techniques for thick, rigid origami-based engineering designs are being developed, origami is becoming increasingly more

attractive as inspiration for complex systems. This paper proposes a process for designing origami-based conceal- and-reveal systems, which can be generalized to design similar thick, rigid origami-based systems. The process

is demonstrated through the development of three conceal-and-reveal systems that present a luxury product to the consumer. The three designs also confirm …

On Limitations Of Uniplex Networks For Modeling Multiplex Contagion, Nicholas W. Landry, Jimi Adams

Faculty Publications

Many network contagion processes are inherently multiplex in nature, yet are often reduced to processes on uniplex networks in analytic practice. We therefore examine how data modeling choices can affect the predictions of contagion processes. We demonstrate that multiplex contagion processes are not simply the union of contagion processes over their constituent uniplex networks. We use multiplex network data from two different contexts- (1) a behavioral network to represent their potential for infectious disease transmission using a "simple"epidemiological model, and (2) users from online social network sites to represent their potential for information spread using a threshold-based "complex"contagion process. Our …

Over the last 2 decades, many African countries have undergone dietary and nutrition transitions fueled by globalization, rapid urbanization, and development. These changes have altered African food environments and, subsequently, dietary behaviors, including food acquisition and consumption. Dietary patterns associated with the nutrition transition have contributed to Africa's complex burden of malnutrition—obesity and other diet-related noncommunicable diseases (DR-NCDs)—along with persistent food insecurity and undernutrition. Available evidence links unhealthy or obesogenic food environments (including those that market and offer energy-dense, nutrient-poor foods and beverages) with suboptimal diets and associated adverse health outcomes. Elsewhere, governments have responded with policies to improve food …

Flood Risk Assessment For Residences At The Neighborhood Scale By Owner/Occupant Type And First-Floor Height, Ayat Al Assi, Rubayet Bin Mostafiz, Carol J. Friedland, Md Adilur Rahim, Robert V. Rohli

Faculty Publications

Evaluating flood risk is an essential component of understanding and increasing community resilience. A robust approach for quantifying flood risk in terms of average annual loss (AAL) in dollars across multiple homes is needed to provide valuable information for stakeholder decision-making. This research develops a computational framework to evaluate AAL at the neighborhood level by owner/occupant type (i.e., homeowner, landlord, and tenant) for increasing first-floor height (FFH). The AAL values were calculated here by numerically integrating loss-exceedance probability distributions to represent economic annual flood risk to the building, contents, and use. A simple case study for a census block in …

How Good Is A Tactical-Grade Gnss + Ins (Mems And Fog) In A 20-M Bathymetric Survey?, Johnson O. Oguntuase, Anand Hiroji, Peter Komolafe

Faculty Publications

This paper examines how tactical-grade Inertial Navigation Systems (INS), aided by Global Navigation Satellite System (GNSS) modules, vary from a survey-grade system in the bath-ymetric mapping in depths less than 20 m. The motivation stems from the advancements in sensor developments, measurement processing algorithms, and the proliferation of autonomous and uncrewed surface vehicles often seeking to use tactical-grade systems for high-quality bathymetric products. While the performance of survey-grade GNSS + INS is well-known to the hydrographic and marine science community, the performance and limitations of the tactical-grade micro-electro-mechanical system (MEMS) and tactical-grade fiber-optic-gyro (FOG) INS aided with GNSS require some …

Moderation Effect Of Community Health On The Relationship Between Racial/Ethnic Residential Segregation And Hiv Viral Suppression In South Carolina: A County-Level Longitudinal Study From 2013 To 2018, Fanghui Shi, Jiajia Zhang Ph.D., Xueying Yang Ph.D., Xiaowen Sun, Zhenlong Li, Chengbo Zeng, Huan Ning, Sharon Weissman, Bankole Olatosi Ph.D., Xiaoming Li Ph.D.

Faculty Publications

Background: Viral suppression is the ultimate goal of the HIV treatment cascade and a primary endpoint of antiretroviral therapy. Empirical evidence found racial/ethnic disparities in viral suppression among people living with HIV (PWH), but the evidence of the relationship between racial/ethnic residential segregation and place-based viral suppression is scarce. Further exploring potential structural moderators in this relationship has substantial implications for healthcare policymaking and resource allocation. The current study aimed to investigate the spatial-temporal disparities in the HIV viral suppression rate across 46 counties in South Carolina from 2013 to 2018. We also examined the impact of racial/ethnic residential segregation …

Speech Regulation And Tobacco Harm Reduction, Jonathan Adler, Jacob James Rich

Faculty Publications

Regulation of commercial speech is a major component of federal regulation of tobacco products. Since adoption of federal tobacco legislation, the Food and Drug Administration has asserted regulatory authority over ENDS and other vaping products as “tobacco products,” subjecting them to the same regulatory regime as traditional tobacco products even though such projects appear to pose less of a threat to public health. Such regulation, and the restriction on truthful speech in particular, may be having negative consequences for public health. Barring producers from informing consumers about the relative risks of vaping products and their potential to reduce smoking eliminates …

Sanctions And Consequences: Third-State Impacts And The Development Of International Law In The Shadow Of Unilateral Sanctions On Russia, Avidan Cover

Faculty Publications

In response to Russia’s invasion of Ukraine, NATO member states and their allies have imposed “unprecedented,” unilateral economic sanctions to hold Russia accountable, degrade its military capability, and limit its international financial access.1 From the outset, sanctioning states such as the United States have stated that they “designed these sanctions to maximize the long-term impact on Russia and to minimize the impact on [themselves and their] allies.”2 These sanctions on an economic power like Russia “have global economic effects far greater than anything seen before.”3 And there is concern that the unintended consequences of the sanctions will disproportionately harm developing …

Understanding Meteorological Changes Following Severe Defoliation During A Strong Hurricane Landfall: Insights From Hurricane Michael (2018), Shannon A. Nelson, Paul W. Miller

Faculty Publications

Despite prompting persistent meteorological changes, severe defoliation following a tropical cyclone (TC) landfall has received relatively little attention and is largely overlooked within hurricane preparedness and recovery plan-ning. Changes to near-track vegetation can modify evapotranspiration for months after tropical cyclone passage, thereby altering boundary layer moisture and energy fluxes that drive the local water cycle. This study seeks to understand poten-tial spatial and temporal changes in defoliation-driven meteorological conditions using Hurricane Michael (2018) as a testbed. In this sensitivity study, two Weather Research and Forecasting (WRF) Model simulations, a normal-landscape and a post-TC scenario, are compared to determine how a …

Sudden Reduction Of Antarctic Sea Ice Despite Cooling After Nuclear War, Joshua Coupe, Cheryl Harrison, Alan Robock, Alice Duvivier, Elizabeth Maroon, Nicole S. Lovenduski, Scott Bachman, Laura Landrum, Charles Bardeen

Faculty Publications

A large-scale nuclear war could inject massive amounts of soot into the stratosphere, triggering rapid global climate change. In climate model simulations of nuclear war, global cooling contributes to an expansion of sea ice in the Northern Hemisphere. However, in the Southern Hemisphere (SH), an initial expansion of sea ice shifts suddenly to a 30% loss of sea ice volume over the course of a single melting season in the largest nuclear war simulation. In smaller nuclear war simulations an expansion in sea ice is instead observed which lasts for approximately 15 years. In contrast, in the largest nuclear war …

Global Sea Surface Cyclogeostrophic Currents Derived From Satellite Altimetry Data, Yuhan Cao, Changming Dong, Alexandre Stegner, Brandon J. Bethel, Chunyan Li, Jihai Dong, L. Haibin, Jingsong Yang

Faculty Publications

Sea surface currents (SSC) derived from the sea surface height anomalies (SSHA) as measured by multi-satellite altimeters are widely used for various applications including studies on ocean dynamics, marine ecology, and climate change. However, present SSC products estimated on the assumption of an idealized geostrophic balance is biased. To overcome this idealization, this study considers flow curvature in the estimation of sea surface velocities in the global ocean, with the computation scheme validated using numerical model results. It is demonstrated that the inclusion of curvature into SSC estimations significantly changes SSC dynamic features in terms of kinetic energy, enstrophy (the …

Floodsafehome: Evaluating Financial Benefits And Savings Of Freeboard For Improved Decision-Making In Flood Risk Mitigation, Carol J. Friedland, Yong Cheol Lee, Rubayet Bin Mostafiz, Jiyoung Lee, Shifat P. Mithila, Robert V. Rohli, Md Adilur Rahim, Ehab Gnan, Monica Teets Farris

Faculty Publications

Freeboard—elevation of a structure above the base flood elevation (BFE)—is a critical component in mitigating or avoiding flood losses. However, the unrevealed benefits and savings of freeboard installation have prevented communities from adopting this approach. To improve decision-making for residents, prospective residents, and other stakeholders in flood-vulnerable communities and enhance flood risk mitigation strategies, this study presents the methodology underlying a new webtool, FloodSafeHome, that estimates comprehensively the economic benefits and savings of freeboard installation for new construction of residential buildings. Specifically, the proposed evaluation framework has been designed to calculate monthly savings for individual buildings by assessing freeboard cost, …

The Criminal Side Of Cryptocurrency, Angelo Kevin Brown

Faculty Publications

As cryptocurrency (crypto) has become more and more popular, so has crypto-related crime. There has been a lack of academic research on crypto-related crime, but it is becoming more prevalent in the last couple of years. Crypto-related crime became especially significant in the impact it had on victims and the awareness of these crimes in the media and the government in late 2019 and early 2020 as various criminal organizations and criminal opportunities opened up as cryptocurrency became mainstream. The common crimes related to cryptocurrency include fraud, theft, and money laundering. In 2021 estimates of crypto-related crime were estimated to …

The International Commitments Of The Fifty States, Ryan M. Scoville

Faculty Publications

U.S. law allocates power to conduct foreign relations primarily to the federal government, but it is well known that states routinely maintain foreign relations of their own. Much of this activity appears to result in legal and political commitments, whether in the form of “sister state” agreements or binding pledges to cooperate on discrete issues such as investment, environmental protection, and transportation. These commitments are at least loosely comparable to international treaties and may either advance or disserve state and national interests.

Yet very little is known about the commitments that are in force. For the most part, neither federal …
