Assessment Of Synthetic Aperture Radar For Classification Of Exposed Coastal Soils In The Great Bay Estuary, Tess Priest

Master's Theses and Capstones

Coastlines around the world are composed of a wide range of sediments. The classification of coastal soil ranges from coarse-grained sediments (gravels and sands, 75 mm to 0.075 mm), to fine-grained sediments (silts and clays, 0.075 mm and smaller). In geotechnical engineering applications, the shear strength of soil is a key characteristic and is commonly influenced by the classification, grain size, and water content of the soil. While site-specific investigation is the best method for obtaining these parameters, information regarding soil type can often be readily accessed from existing literature as a general classification. However, soil type can vary at …

Dirt/Μ: Automated Extraction Of Root Hair Traits Using Combinatorial Optimization, Peter Pietrzyk, Neen Phan-Udom, Chartinun Chutoe, Lise Pingault, Ankita Roy, Marc Libault, Patompong Johns Saengwilai, Alexander Bucksch

Department of Entomology: Faculty Publications

As with phenotyping of any microscopic appendages, such as cilia or antennae, phenotyping of root hairs has been a challenge due to their complex intersecting arrangements in two-dimensional images and the technical limitations of automated measurements. Digital Imaging of Root Traits at Microscale (DIRT/μ) is a newly developed algorithm that addresses this issue by computationally resolving intersections and extracting individual root hairs from two-dimensional microscopy images. This solution enables automatic and precise trait measurements of individual root hairs. DIRT/μ rigorously defines a set of rules to resolve intersecting root hairs and minimizes a newly designed cost function to combinatorically identify …

Application Of Surge Arrester In Limiting Voltage Stress At Direct Current Breaker, Mohammadamin Moghbeli, Shahab Mehraeen, Sudipta Sen

Faculty Publications

Hybrid DC circuit breakers combine mechanical switches with a redirecting current path, typically controlled by power electronic devices, to prevent arcing during switch contact separation. The authors’ past work includes a bipolar hybrid DC circuit breaker that effectively redirects the fault current and returns it to the source. This reduces arcing between the mechanical breaker’s contacts and prevents large voltage overshoots across them. However, the breaker’s performance declines as the upstream line inductance increases, causing overvoltage. This work introduces a modification to the originally proposed hybrid DC breaker to make it suitable to use anywhere along DC grid lines. By …

Providing Independent-Learning Space To Promote English Learners’ Self-Regulation, Anastasia Nelladia Cendra, Alberik Ryan Tendy Wijaya

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

Independent learning is a powerful way to enhance English mastery. Yet, its effect on self-regulation is not yet explored further. This research investigated that matter by answering the following questions: 1) How is the independent learning activity per-ceived by English learners? 2) Can independent learning activities assist English learners in developing self-regulation skills? Twenty-nine university-level English learners participated in this qualitative-descriptive research which uses an open-ended questionnaire and interview. This study showed that independent learning is perceived positively by the participants. They mentioned that independent learning gave them more chances to understand the materials. Furthermore, they believed that the main …

The Influence Of The Race Of Defendant And The Race Of Victim On Capital Charging And Sentencing In California, Catherine M. Grosso, Jeffrey A. Fagan, Michael Laurence

Faculty Scholarship

The California Racial Justice Act of 2020 recognized racial and ethnic discrimination as a basis for relief in capital cases, expressly permitting several types of statistical evidence to be introduced. This statewide study of the influence of race and ethnicity on the application of capital punishment contributes to this evidence. We draw on data from over 27,000 murder and manslaughter convictions in California state courts between 1978 and 2002. Using multiple methods, we found significant racial and ethnic disparities in charging and sentencing decisions. Controlling for defendant culpability and specific statutory aggravators, we show that Black and Latinx defendants and …

Three-Dimensionalization Mediates The Subjective Experience Of Fractal Interior Spaces, Joori Suh, William Stalker, Steen Pedersen, Assaf Harel

Psychology Faculty Publications

A fractal, a self-similar organic or geometric pattern that repeats at varying scales, is one of the most compelling characteristics found in nature. Previous studies on fractal patterns have demonstrated consistent trends in potential psychological benefits, such as stress reduction. However, we fall short of understanding one of the essential properties of fractals found in nature, i.e., the three-dimensionality of their appearance. In this study, we aimed at understanding the role of the three-dimensionalization of fractal patterns in spatial structures on human subjective perceptual experience. Two hundred seventy three-dimensional spatial prototype models were created for this study, spanning two dimensions: …

Thai Parents’ Reasons For Sending Their Children To Premium-Fee International Schools: Strategies For Establishing International Schools, Issara Wongcharoensin

College of Education Theses and Dissertations

The study investigates the factors influencing Thai parents’ decisions when selecting international schools in the Bangkok Metropolitan Region. It examines how parents’ preferences for educational outcomes shape their choice among UK, US, or IB programs. Key findings reveal that dissatisfaction with Thai public schools drives many families to enroll their children in international schools. These institutions are valued for their supportive community atmosphere, opportunities for foreign college placements, and superior infrastructure. Preferences for different programs reflect distinct priorities: UK programs are preferred for their extracurricular activities, punctuality, and academic reputation; US programs for their emphasis on critical thinking, multiculturalism, and …

Is Distance From Innovation A Barrier To The Adoption Of Artificial Intelligence?, Jennifer Hunt, Iain Cockburn, James Bessen

Faculty Scholarship

Using our own data on Artificial Intelligence publications merged with Burning Glass vacancy data for 2007-2019, we investigate whether online vacancies for jobs requiring AI skills grow more slowly in U.S. locations farther from pre-2007 AI innovation hotspots. We find that a commuting zone which is an additional 200km (125 miles) from the closest AI hotspot has 17% lower growth in AI jobs’ share of vacancies. This is driven by distance from AI papers rather than AI patents. Distance reduces growth in AI research jobs as well as in jobs adapting AI to new industries, as evidenced by strong effects …

Beyond Environmental Harm: Industry Claims, Lived Experiences, And The Impacts Of Gas Extraction, Martina Angela Caretta, Melissa Haeffner, Ryan Emanuel, Racheal Hood, Julia Seydel

Environmental Science and Management Faculty Publications and Presentations

The peer-reviewed literature presents overwhelming evidence that fossil fuel based energy infrastructure projects are responsible for lower residential property values, environmental destruction and pollution that decrease residents' quality of life. These projects also challenge local people's sense of identity and even the threat of such a project can make residents question their sense of place. As evidence, we first present a bibliographic analysis of the environmental impact statements for the Mountain Valley Pipeline in West Virginia and the Jordan Cove Energy Project in Oregon. We find that their approval processes relies on non-peer-reviewed, industry-funded claims that pipelines will bring economic …

Precision Measurement Of The Absolute Energy Of The 2s3s 1S0 State In Neutral 9Be, K. J. Ahrendsen, T. Karani, W. D. Williams

Physics: Faculty Publications

We report on the absolute energy of the 2⁢��⁢3⁢��⁢1⁢��0 state in neutral 9Be. In doing so, we measure the transition frequencies of the 2⁢��2⁢1⁢��0→ 2⁢��⁢2⁢��⁢1⁢��∘1 and 2⁢��⁢2⁢��⁢1⁢��∘1→ 2⁢��⁢3⁢��⁢1⁢��0 transitions, also determining the absolute energy of the 2⁢��⁢2⁢��⁢1⁢��∘1 state. The results are obtained from a home-built hollow cathode discharge lamp using saturated absorption spectroscopy with laser frequencies referenced to a frequency comb. The transition frequencies are determined to be 1276080080⁢(50) and 363105650⁢(130) MHz for the 2⁢��2⁢1⁢��0→ 2⁢��⁢2⁢��⁢1⁢��∘1 and 2⁢��⁢2⁢��⁢1⁢��∘1→ 2⁢��⁢3⁢��⁢1⁢��0 transitions, respectively. The absolute energies are determined to be 42565.4498⁢(17) and 54677.350⁢(5) cm−1 for the 2⁢��⁢2⁢��⁢1⁢��∘1 and 2⁢��⁢3⁢��⁢1⁢��0 states, respectively. The …

Willingness To Pay And Market Potential For Biowrap: An Economic Study Of A New Biodegradable Mulch Product In Home Gardening, Gengchen Cai

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This study explores the market potential of BioWRAP, a biodegradable sprayable weed suppression product, by assessing the willingness to pay (WTP) among American home gardeners. Traditional plastic mulch offers significant agronomic benefits but poses considerable environmental challenges, making BioWRAP a promising alternative due to its similar benefits and reduced environmental impact. Using a double-bounded contingent valuation method, we analyze the WTP for BioWRAP among different demographic groups and gardening practices. Our findings indicate that the highest WTP for BioWRAP is among home gardeners who currently use chemical sprays for weed suppression, followed by those using physical barriers, with the lowest …

Glass Ceilings, Step Stools, And Sticky Floors: The Racialized Gendered Promotion Process, Christianne Corbett, Katherine E. Wullert, Shannon K. Gilmartin, Caroline Simard

Sociology and Criminology Faculty Publications and Presentations

Organizations play a central role in replicating societal inequalities. Despite theories of gendered and racialized organizations, evidence of unequal outcomes, and research on proposed mechanisms, we have few intersectional analyses demonstrating how the promotion process varies by race and gender across job levels in actual organizations. In this first-ever analysis of advancement in a U.S. firm by gender, race, and job, we run random effects logistic regression models on five years of novel longitudinal data from the software engineering workforce of a U.S.-based technology company. Results show intersectional performance-reward bias in patterns that help maintain the racialized gendered hierarchy so …

Regiongrow3d: A Deterministic Analysis For Characterizing Discrete Three-Dimensional Landslide Source Areas On A Regional Scale, Nicolas W. Mathews, Ben A. Leshchinsky, Benjamin B. Mirus, Michael J. Olsen, Adam M. Booth

Geology Faculty Publications and Presentations

Regional-scale characterization of shallow landslide hazards is important for reducing their destructive impact on society. These hazards are commonly characterized by (a) their location and likelihood using susceptibility maps, (b) landslide size and frequency using geomorphic scaling laws, and (c) the magnitude of disturbance required to cause landslides using initiation thresholds. Typically, this is accomplished through the use of inventories documenting the locations and triggering conditions of previous landslides. In the absence of comprehensive landslide inventories, physics-based slope stability models can be used to estimate landslide initiation potential and provide plausible distributions of landslide characteristics for a range of environmental …

Pias: Privacy-Preserving Incentive Announcement System Based On Blockchain For Internet Of Vehicles, Yonghua Zhan, Yang Yang, Hongju Cheng, Xiangyang Luo, Zhuangshuang Guan, Robert H. Deng

Research Collection School Of Computing and Information Systems

More vehicles are connecting to the Internet of Things (IoT), transforming Vehicle Ad hoc Networks (VANETs) into the Internet of Vehicles (IoV), providing a more environmentally friendly and safer driving experience. Vehicular announcement networks show promise in vehicular communication applications. However, two major issues arise when establishing such a system. Firstly, user privacy cannot be guaranteed when messages are forwarded anonymously, thus the reliability of these messages is in question. Secondly, users often lack interest in responding to announcements. To address these problems, we introduce a Blockchain-based incentive announcement system called PIAS. This system enables anonymous message commitment in a …

Sound And Complete Witnesses For Template-Based Verification Of Ltl Properties On Polynomial Programs, Krishnendu Chatterjee, Amir Goharshady, Ehsan Goharshady, Mehrdad Karrabi, Dorde Zikelic

Research Collection School Of Computing and Information Systems

We study the classical problem of verifying programs with respect to formal specifications given in the linear temporal logic (LTL). We first present novel sound and complete witnesses for LTL verification over imperative programs. Our witnesses are applicable to both verification (proving) and refutation (finding bugs) settings. We then consider LTL formulas in which atomic propositions can be polynomial constraints and turn our focus to polynomial arithmetic programs, i.e. programs in which every assignment and guard consists only of polynomial expressions. For this setting, we provide an efficient algorithm to automatically synthesize such LTL witnesses. Our synthesis procedure is both …

Enhancing Multi-Agent System Testing With Diversity-Guided Exploration And Adaptive Critical State Exploitation, Xuyan Ma, Yawen Wang, Junjie Wang, Xiaofei Xie

Research Collection School Of Computing and Information Systems

Multi-agent systems (MASs) have achieved remarkable success in multi-robot control, intelligent transportation, and multiplayer games, etc. Thorough testing for MAS is urgently needed to ensure its robustness in the face of constantly changing and unexpected scenarios. Existing methods mainly focus on single-agent system testing and cannot be directly applied to MAS testing due to the complexity of MAS. To our best knowledge, there are fewer studies on MAS testing. While several studies have focused on adversarial attacks on MASs, they primarily target failure detection from an attack perspective, i.e., discovering failure scenarios, while ignoring the diversity of scenarios. In this …
