Operating since 2004, the Pierre Auger Observatory has led to major advances in our understanding of the ultra-high-energy cosmic rays. The latest findings have revealed new insights that led to the upgrade of the Observatory, with the primary goal of obtaining information on the primary mass of the most energetic cosmic rays on a shower-by-shower basis. In the framework of the upgrade, called AugerPrime, the 1660 water-Cherenkov detectors of the surface array are equipped with plastic scintillators and radio antennas, allowing us to enhance the composition sensitivity. To accommodate new detectors and to increase experimental capabilities, the electronics is also …

Flourishing, Virtue, And The Common Good Constitutionalism, Lawrence B. Solum

Faculty Scholarship

In Common Good Constitutionalism, Professor Adrian Vermeule articulates a conception of the common good. Vermeule has much to say about the common good, but very little to say about the substantive component of his conception, which he describes as “happiness or flourishing.” This Article articulates a conception of the common good that is grounded in a virtue-centered conception of human flourishing. Humans are rational and social creatures, and therefore, flourishing for humans consists in rational and social activities that express the human excellence or virtues. The common good requires communities that facilitate human flourishing in three ways: (1) by creating …

U.S.-Canadian Wildfire Cooperation, Nicholas Smetzer

The International Law Review Association Student Forum

Record-breaking wildfires are striking the United States and Canada with troubling, increasing frequency. As wildfires know no borders, climate change-related wildfires will increasingly damage the ecosystems and economies of both nations unless they develop an efficient system of cooperation to deal with this shared threat. As the U.S. and Canada share similar cultures, legal systems, and interests in preserving their ecosystems and air qualities, these countries are in a unique position to share intelligence and resources to properly address the scale of these disasters. Scholars such as Madison Gaffney have noted the potential for current legislation to expand and treat …

A Holistic Approach To Include Sic And Design The Optimal Extrudate Catalyst For Hydrogen Production–Reforming Routes, Ali M. Alkadhem, Fernanda Tavares, Natalia Realpe, Gontzal Lezcano, Arief Yudhanto, Mohammad Subah, Vasco Manaças, Jacek Osinski, Gilles Lubineau, Pedro Castaño

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Reforming processes are the backbone of hydrogen production routes, given the flexibility of their feedstock, such as methane, carbon dioxide, ammonia, waste plastics, or biomass. Heat transfer is a drawback at the industrial scale, reducing efficiency. We incorporate SiC in the technical composite, extrudate catalyst and develop a holistic approach to optimize and understand the effect of each constituent and its mixtures. We apply Ni-Ce as an active phase, bentonite or kaolin as a binder, alumina as a filler, and carborundum as the heat-transport carrier. We characterize the extrudate catalysts using various techniques, including crushing strength and thermal conductivity. We …

Neural Modulation Enhancement Using Connectivity-Based Eeg Neurofeedback With Simultaneous Fmri For Emotion Regulation, Amin Dehghani, Hamid Soltanian-Zadeh, Gholam-Ali Hossein-Zadeh

Research Administration Articles

Emotion regulation plays a key role in human behavior and overall well-being. Neurofeedback is a non-invasive self-brain training technique used for emotion regulation to enhance brain function and treatment of mental disorders through behavioral changes. Previous neurofeedback research often focused on using activity from a single brain region as measured by fMRI or power from one or two EEG electrodes. In a new study, we employed connectivity-based EEG neurofeedback through recalling positive autobiographical memories and simultaneous fMRI to upregulate positive emotion. In our novel approach, the feedback was determined by the coherence of EEG electrodes rather than the power of …

Constitutional Resilience, Shannon M. Roesler

Washington and Lee Law Review

Since the New Deal era, our system of constitutional governance has relied on expansive federal authority to regulate economic and social problems of national scale. Throughout the twentieth century, Congress passed ambitious federal statutes designed to address these problems. In doing so, it often enlisted states as regulatory partners—creating a system of shared governance that underpins major environmental statutes, such as the Clean Water Act and the Clean Air Act. These governance structures remain important today as we seek to adapt our laws and institutions to the serious disruptions of climate change. But recent Supreme Court decisions challenge this long-established …

Regulating Co2 Emissions Post-West Virginia V. Environmental Protection Agency, Rebecca J. Davis, Justin Blount

William & Mary Environmental Law and Policy Review

In West Virginia v. Environmental Protection Agency, the Supreme Court expressly adopted the major questions doctrine and used it to invalidate the Clean Power Plan, a rule intended to reduce carbon dioxide emissions from power plants. This opinion has been controversial and has left many commentators concerned that it may hamper the ability of administrative agencies to aggressively and flexibly regulate.

This Article analyzes this opinion and the impact it may have on ongoing efforts to regulate carbon dioxide emissions at the federal level. It then examines economic theory underpinning environmental regulation, developing technologies to reduce carbon dioxide emissions, …

Fueling A Hydrogen Boom: Federal And State Policies For Promoting Green Hydrogen, Kayna Lantz, Luke Sower

William & Mary Environmental Law and Policy Review

“Green” hydrogen produced from renewable energy sources could play a valuable role in the energy transition. Among other things, green hydrogen’s potential as a source of carbon-free, long-term energy storage could help the nation address the intermittency-related challenges associated with growing reliance on wind and solar power. Green hydrogen also has promise as an energy-dense fuel for industries that are difficult to electrify, such as long-haul transportation and steel and fertilizer manufacturing. Recent federal actions have provided some initial government support for green hydrogen technologies, but significant policy gaps remain. States and the federal government could do much more to …

Preparing For The Flood: Virginia Local Governments' Stormwater Management Liability, James E. Davidson

William & Mary Environmental Law and Policy Review

This Note explains that modern interpretations of Virginia Code § 15.2-970 have made Virginia municipalities immune to tort suits arising from the negligent maintenance of stormwater systems. Due to the Virginia Supreme Court’s holdings in Livingston v. Virginia Department of Transportation and other inverse condemnation suits, localities may be found liable when their stormwater management decisions cause property damage. However, following the Court’s holding in AGCS Marine Insurance Co. v. Arlington County, which prevented inverse condemnation claims arising from municipal negligence, residents are still unlikely to find legal redress for negligent stormwater management that results in property damage. Therefore, this …

Interfacial Thermomechanical Behavior Of Hybrid Carbon Fibers, Sriraj Srihari

Doctoral Dissertations and Master's Theses

The carbon fiber/epoxy interface is of great importance in composite design due to its load transfer mechanisms from the weak epoxy to the stronger fiber. Improving the strength of the interface reduces the risk of failure at the interface and improves the load transfer to the fiber. In this study, two types of nano-species ZnO nanowires and nickel-based metal organic frameworks were grown on carbon fibers to improve the interfaces. The interfacial mechanics of the enhanced fibers are evaluated using nanoindentation studies. Composite samples with Aeropoxy matrix and vertically aligned fibers are fabricated for this purpose. A Bruker TI-980 TriboIndenter …

Explorations In Monocular Distance And Ranging (Modar) Techniques For Real-World Applications, Devon Vail

Doctoral Dissertations and Master's Theses

In this work, an initial prototype of a monocular camera system capable of retrieving depth-from-focus using a liquid focus-tunable lens is constructed out of hobby-grade photography equipment. This concept has been explored previously in laboratory settings using specialized equipment; this work seeks to determine the feasibility of retrieving depth-from-focus using commercially available components. To achieve this, an iterative exploration of existing techniques was performed to verify their utility in the final ensemble of processes to retrieve depth from 2D images. Initially, blurry images were simulated by applying Gaussian blur to test images to verify the functionality of a Laplacian of …

Spoken Language Processing And Modeling For Aviation Communications, Aaron Van De Brook

Doctoral Dissertations and Master's Theses

With recent advances in machine learning and deep learning technologies and the creation of larger aviation-specific corpora, applying natural language processing technologies, especially those based on transformer neural networks, to aviation communications is becoming increasingly feasible. Previous work has focused on machine learning applications to natural language processing, such as N-grams and word lattices. This thesis experiments with a process for pretraining transformer-based language models on aviation English corpora and compare the effectiveness and performance of language models transfer learned from pretrained checkpoints and those trained from their base weight initializations (trained from scratch). The results suggest that transformer language …

Teacher Self-Efficacy And The Inclusive Christian School Classroom, Richard J. Mudrow

Doctor of Education (Ed.D)

Research indicates that one in five students nationwide struggles with a learning difficulty or disability that affects the student’s ability to learn (Galiatsos et al., 2019). Nationwide, Christian schools are enrolling students with disabilities (SWDs), but it is difficult to determine the specific number of SWDs enrolled in Christian schools (Association of Christian Schools International, 2021). In the inclusive school setting, whether public or private, teachers and administrators are often underprepared in their approach to the education of SWDs (Cooc, 2019; Kirk et al., 2021; Krämer et al., 2021). The purpose of this study is to explore how teaching SWDs …

Using Industry Sector Entropy To Predict Economic Community Disaster Resilience: Real-World Verification From The Covid-19 Pandemic, Thomas Brindle

Dissertations

The COVID-19 pandemic has presented an opportunity for disaster science researchers to gain insight into the underlying nature of community resilience through comparing the socioeconomic effects of government action to a common threat across urban population centers of varying economic compositions. For example, the negative effects of the COVID-19 pandemic on employment related to public health mitigation efforts in the leisure and hospitality sector of Las Vegas, NV, during the onset of the pandemic were well publicized. In comparison, other population centers of similar size but with different economic sector composition varied in the degree to which employment were affected, …

Seabed Reflection Coefficient Variability In The Mono Lake Using Seismic Reflection Sparker Data, Francis Nnamdi Okeifufe

Earth Sciences Theses and Dissertations

Acoustic reflections from a lakebed provide valuable information about the dynamic boundary between water and the lakebed, where sediments and biota in the water column eventually settle. In this study, we present a comprehensive analysis of reflected sound wave amplitudes to gain insights into the physical properties of a water-sediment boundary. We decided to carry out this analysis within the unique ecosystem of the Mono Lake basin due to the fact that the Mono Lake, a meromictic and hypersaline waterbody is situated within one of the most active yet understudied volcanic regions in the United States. The fact that the …

Design And Validation Of A Variable Stiffness Three Degree Of Freedom Planar Robot Arm, Andrew L. Bernhard

Master's Theses (2009 -)

The need exists for robotic manipulators that can interact with an environment having uncertain kinematic constraints. A robot has been designed and built for proof of concept of a passive variable compliance control strategy that can vary joint stiffness to achieve higher performance dexterous manipulation. This novel planar robot incorporating variable stiffness actuators and common industrial controls allows the robot to comply with its environment when needed but also have high stiffness for precise motion control in free space. To perform both functions well, a high stiffness ratio (max/min stiffness) is required. A stiffness ratio up to 492 was achieved. …

MXene, for example, can be designed for specialized applications using a plethora of element combinations and surface termination layers, making them attractive for highly optimized multifunctional com- posites. Although multiple critical engineering applications demand that such composites balance specialized functions with mechanical demands, the current knowledge of the mechanical perfor- mance and optimized traits necessary for such composite design is severely …

Coir/Glass Hybrid Fiber Reinforced Thermoset Polymer Composite Laminates With Room-Temperature Self-Healing And Shape Memory Functions, Sakil Mahmud, John Konlan, Jenny Deicaza, Guoqiang Li

Faculty Publications

Natural fibers have a lot of potentials as renewable reinforcements for polymers. However, their lower load-carrying capacity compared with synthetic fibers made it a challenge to use them as polymer reinforcements. When a laminated composite beam is bent, the normal stress is the highest on the top and bottom layers and zero in the midplane due to the (non)linear distribution of normal strain. Even though the shear stress is the highest in the midplane, most polymers can tolerate the high shear stress. Therefore, hybrid composite laminates with strong synthetic glass fibers stacked over the core of weak natural coir fiber …

Machine-Learning-Based Thermal Conductivity Prediction For Additively Manufactured Alloys, Uttam Bhandari, Yehong Chen, Huan Ding, Congyuan Zeng, Selami Emanet, Paul R. Gradl, Shengmin Guo

Faculty Publications

Thermal conductivity (TC) is greatly influenced by the working temperature, microstructures, thermal processing (heat treatment) history and the composition of alloys. Due to computational costs and lengthy experimental procedures, obtaining the thermal conductivity for novel alloys, particularly parts made with additive manufacturing, is difficult and it is almost impossible to optimize the compositional space for an absolute targeted value of thermal conductivity. To address these difficulties, a machine learning method is explored to predict the TC of additive manufactured alloys. To accomplish this, an extensive thermal conductivity dataset for additively manufactured alloys was generated for several AM alloy families (nickel, …

Additive Friction Stir Deposition Of Metallic Materials: Process, Structure And Properties, Jiayun Shao, Arash Samaei, Tianju Xue, Xiaoyu Xie, Shengmin Guo, Jian Cao, Eric Macdonald, Zhengtao Gan

Faculty Publications

Additive friction stir deposition (AFSD) is a relatively new additive manufacturing technique to fabricate parts in solid state below the melting temperature. Due to the solid-state nature, AFSD benefits from lower residual stresses as well as significantly lower susceptibility to porosity, hot-cracking, and other defects compared to conventional fusion-based metallic additive manufacturing. These unique features make AFSD a promising alternative to conventional forging for fabricating large structures for aerospace, naval, nuclear, and automotive applications. This review comprehensively summarizes the advances in AFSD, as well as the microstructure and properties of the final part. Given the rapidly growing research in AFSD, …
