Focal Engine: Filling A Gap Between Game Engines And Big-Data Scientific Visualization Packages, Kindrat Beregovyi

Doctoral Dissertations

This dissertation presents Focal Engine, a novel 3D visualization engine designed to bridge the gap between game engines and scientific visualization tools. Game engines offer accessible interfaces and high-performance rendering but struggle with large-scale scientific datasets, while tools like ParaView and VTK handle complex data structures effectively but lack intuitive editing capabilities and modern rendering features. Focal Engine combines the accessibility and rendering performance of game engines with the data handling capabilities and analytical tools of scientific visualization platforms. The engine's capabilities are validated through multiple applications and projects, for example: HabiCAT 3D performs 3D complexity measurements on ocean floor …

Pitch Modeling And Control Of Subcarangiform Robotic Fish, Margaret Grace Enderle

Master's Theses and Capstones

The development of biomimetic robotic fish has been an ongoing research topic for the last 30 years. Here, researchers have explored biomimetic propulsion and maneuverability mechanisms, studied energy efficiency in comparison to live fish, and developed autonomous control algorithms for these extremely nonlinear systems. This work studies a multi-linkage, single-actuator propelled biomimetic robotic fish, the Ghost Uncrewed Performance Platform Submersible (GUPPS), developed at the University of New Hampshire. A set of symmetrically driven, static pectoral fins are added to the original platform to enable diving and surfacing capabilities by controlling the vehicle Angle of Attack (AoA) through pitch and yaw …

Rapid Incorporation But Contrasting Stability Of Fertilizer Versus Litter Nitrogen In Mineral-Associated Organic Matter, Emma Bergh

Master's Theses and Capstones

Nitrogen (N) is abundant in agricultural soils during early spring due to both decomposing plant residues and initial fertilizer applications before peak crop uptake. This N is vulnerable to loss through leaching and denitrification, but a portion of this N can become stabilized in mineral-associated organic matter (MAOM). However, the short-term incorporation and long-term stability of different N sources within MAOM remain poorly understood. This study examined how fertilizer and litter derived N are incorporated and stabilized in MAOM using a three-week incubation experiment with 15N labeled fertilizer, rye root, and rye shoot additions to paired cropland and grassland soils. …

Potential Predictors Of Nonconductive Wood Column Volumes In Five Maple Species, Tanner Ryan Frost

Master's Theses and Capstones

Maple tapping guidelines rely on the understanding of nonconductive wood column (NWC) formation, but this process has only been studied in sugar maple and may be ineffective at advising producers in their tapping activities due to the variation in wounding between sites and the lack of research into alternative species more recently being brought to market. The goal of this study was to investigate sap sugar concentrations and sap yields as predictors of nonconductive wood column (NWC) volumes in five Acer species: sugar maple (Acer saccharum), red maple (Acer rubrum), silver maple (Acer saccharinum), Norway maple (Acer platanoides), and boxelder …

Weaponized Deepfakes: A Low-Resourced Attacker Threat Assessment, Joshua David Labelle

Master's Theses and Capstones

The democratization of Artificial Intelligence and Machine Learning (AI/ML) tools, combined with the short-form nature of modern media consumption, has created a ripe landscape for generating and weaponizing synthetic media. The availability of pre-trained, open-source generative models enables would-be attackers, who lack funding and enterprise-grade hardware, to conduct convincing information-based attacks that harm, manipulate, and deceive. This thesis aims to model this threat actor using an open-source deepfake generation pipeline that requires minimal computational resources and is capable of producing deepfakes in the audio, image, and video domains. This model is then used to identify, measure, and evaluate the capabilities …

Characterizing Sei Whale (Balaenoptera Borealis) Movement Patterns In The Gulf Of Maine, Emma Vergow

Master's Theses and Capstones

Sei whales are difficult to visually monitor due to their cryptic presence and lack of breaching. Passive acoustic monitoring has the potential to expand knowledge of sei whale movement ecology. The present study characterizes sei whale movement patterns related to migration dynamics in the Gulf of Maine. Five bottom-mounted Acoustic Long-Term Observatory landers, each equipped with a tetrahedral array of omni-directional hydrophones, were deployed throughout the Gulf of Maine as part of the Acoustic and Environmental Observation Network (AEON) in the Northwest Atlantic project. A combination of manual and automated detections was used to assess sei whale daily and seasonal …

Now You See It: Evaluating A Small Object Detection Model For Uncrewed Surface Vehicle Operations, Jenna Ehnot

Master's Theses and Capstones

As Uncrewed Surface Vehicle (USV) operations scale in size, distance, and complexity, they increasingly rely on artificial intelligence (AI) algorithms to maintain situational awareness, and operators must understand how algorithm performance may change as camera configuration is adjusted to meet operational needs. This thesis proposes distance-based evaluation strategies that characterize object detection performance in terms directly applicable to USV operations. In this research, a YOLOv5s model was trained to detect small maritime obstacles, focusing on aids to navigation, and the lobster pot floats common in the Gulf of Maine. Three test videos were collected, each capturing a buoy approaching the …

Quantifying Contributions Of Sonar Systems On Marine Soundscapes: A Statistical And Machine Learning Analysis, Reilly Jacob Lessard

Master's Theses and Capstones

A variety of elements are used to characterize marine soundscapes, including natural and anthropogenic sound. One anthropogenic activity that potentially contributes to marine soundscapes, but is not sufficiently understood, is the use of different types of ocean-mapping sonar systems. Sonar systems are used abundantly in marine environments for purposes such as ocean floor mapping and military security purposes [Ryu et al., 2023] [Marszal and Salamon, 2013]. The systems used to conduct this research are the Kongsberg TOPAS PS40 sub-bottom profiler and the RESON SeaBat T51-R multibeam echosounder, along with SoundTrap recorders, which were deployed in the Gulf of Maine. Periods …

How Human Personality Will Change With The Use Of Artificial Intelligence, John Mayer

UNH Personality Lab

INTRODUCTION: Human personality changes in response to new habits, situations, and maturation, among other causes. As people interact with artificial intelligence (AI), their personalities are likely to change, from their emotional responses to their self-concept.

METHODOLOGY: This theoretical account draws together empirical studies of how personality changed in response to past technological innovations, changes in personal interactions observed in people’s AI usage, changes that arise from the use and disuse of cognitive skills, and works on the self-concept. Research reports in the review were selected according to their relevance and quality.

THEORETICAL STATEMENT: While AI becomes increasingly human-like, humans increasingly …

Nitrogen Oxides In The Remote Marine Environment: Implications For Oceanic Emissions And Photolysis Of Particulate Nitrate, Foroozan Arkian, Chelsea Thompson, Jeff Peischl, Ilann Bourgeois, Jack E. Dibb, Jose L. Jimenez, Pedro Campuzano-Jost, Jianghanyang Li, Steven Morey, Brian C. Mcdonald, Steven Wofsy, Siyuan Wang

Faculty Publications

Nitric oxide (NO) in the remote marine atmosphere is underestimated by chemistry-climate models. We explore the potential oceanic emissions of NO and its impacts using a global chemistry-climate model with a newly developed oceanic NO emission inventory, considering the abiotic photochemical production of NO in the seawater. The results are evaluated using global observations from the NASA Atmospheric Tomography Mission (ATom). We propose that the photochemical production of NO from the photolysis of dissolved inorganic nitrite and nitrate in the surface seawater could lead to an oceanic NOx source of ∼3 Tg N per year, which could explain the missing …

Contracting For Consumer Trade Compliance, Christine Abely

Law Faculty Scholarship

Export compliance is becoming increasingly important for parties required to abide by U.S. law, including many online sellers of consumer products. These retailers' contractual terms with their customers set forth a number of provisions governing the relationship between them, including those which deal with arbitration, indemnification, disclaimer of warranties, and other issues. Many such agreements also purport to create obligations on the part of the consumer as to export control and sanctions compliance relative to the products they purchase. These contract provisions attempt to do so, however, in often markedly different ways, and with language that may leave notable gaps …

Evaluating The Effects Of Agricultural Management Practices On Beneficial Arthropod Communities, Isaac Newton Ativor

Doctoral Dissertations

Arthropods provide essential ecosystem services to our agricultural landscapes. These ecosystem services include biological control of pest organisms, including weed seeds, and plant pollination. Concerningly, however, there has been a global decline in insect populations over the last decade, a major cause of which is agricultural intensification. Previous research has demonstrated that agricultural management practices can strongly influence the species composition and abundance of arthropod communities, and therefore presumably the ecosystem services or disservices these organisms provide; however, our understanding of these interactions remains limited. I conducted three studies to investigate whether agricultural practices common in annual row crop (tillage …

Interpolated Factored Green's Function (Ifgf) Method Of Acceleration For Electromagnetic Scattering Off Of A Perfectly Electrically Conducting Surface, Mathew D'Amico

Doctoral Dissertations

Boundary integral equation (BIE) methods are advantageous in scattering problems due to their reduction of the problem's dimensionality as well as their automatic satisfaction of far-field radiation conditions. Specifically, for electromagnetic scattering off of perfectly electrically conducting (PEC) geometries, we are concerned with the magnetic field integral equation (MFIE). Typically, BIE implementation is iterative, with each direct integration requiring $\mathcal{O}(N^2)$ operations for a grid size $N$. For large $N$, this incurs very large computation times. To date, all existing methods that reduce the asymptotic operational complexity of evaluating the MFIE integral to $\mathcal{O}(N\log N)$ rely on use of the Fast …

Reentry, Justice Involvement, And Evolving Perspectives: Moving Toward Rehabilitation?, Casey Cavanaugh

Doctoral Dissertations

As prison populations climb, it is inevitable that the vast majority of incarcerated individuals will eventually return to the community. As they return, they face numerous barriers resulting from their incarceration. While it is important to identify barriers to reentry, it is also important to identify facilitators of reentry, which include forces that may mitigate reentry challenges. A tool is needed to measure this comprehensive list of barriers and facilitators, and in doing so, one may identify improvements and successes that stretch beyond merely that of recidivism. “Successful” reentry is typically measured through low recidivism rates, which recent government reports …

Investigations Into Prior Knowledge And Self-Efficacy As Predictors Of Exam Performance In General Chemistry, And Student Interactions With Chemistry Textbooks, Gordon Hunter

Doctoral Dissertations

The first chapter addresses the validity and reliability of the Motivated Strategies for Learning Questionnaire (MSLQ) as a tool for chemistry education research. The study shows that the original MSLQ did not meet modern standards of reliability and presents a modified version that better captures self-efficacy in chemistry-specific contexts. The revised instrument shows improved model fit, reinforcing the importance of refining assessment tools for chemistry education research.The effects of prior knowledge and self-efficacy on student performance in a first-semester general chemistry course are investigated in the second chapter. Self-efficacy, defined as a learner's belief in their capability to successfully accomplish …

Planning Responses To Drinking Water System Emergencies, Jingyan Huang

Doctoral Dissertations

Despite extensive efforts to ensure clean and safe drinking water, drinking water contamination emergencies remain a persistent challenge in the United States. These events can result in widespread public health impacts, economic losses, and long-term environmental damage, particularly when triggered by hazardous chemical releases. Effective management of such crises requires a dual focus on both technical preparedness and human decision-making. This dissertation addresses these challenges through a two-part investigation that bridges pre-incident planning and post-incident response. It is guided by two core research objectives: (1) to evaluate commonly applied emergency countermeasures from both resilience and sustainability perspectives; and (2) to …

Psychological Factors Of Acting Talent And Success: You've Got "It", Lorelei Tierney Himlin

Doctoral Dissertations

The goal of an actor is to become invisible, bringing a character to life so convincingly that the audience forgets the actor exists outside the role. Different schools of acting often describe differing methods of portraying characters to this same general effect. To followers of the Meisner school, for example, “acting is behaving truthfully under imaginary circumstances” (Meisner et al., 1987). The “truthful” part involves creating a comprehensive mental model of a character’s imagined personality in order to fully embody that personality and extrapolate it to a situation. Then the actor uses a variety of acting techniques to think and …

Black Hole-Neutron Star Mergers: Numerical Relativity Studies Of Remnant Matter, Gravitational Waveforms, And Automated Simulation Workflows, Tia Kathleen Martineau

Doctoral Dissertations

Black hole–neutron star (BHNS) mergers are key sources for multimessenger astrophysics, offering insight into strong-field gravity and the behavior of matter at supranuclear densities. This dissertation presents three independent contributions to the study of BHNS systems using the Spectral Einstein Code (SpEC). First, a set of simulations spanning a range of mass ratios, black hole spins, and neutron star equations of state is used to map disruption thresholds and quantify remnant disk masses, unbound ejecta, and ejecta composition. These results are compared to predictions from remnant mass model FNH18, to assess its reliability in accurately predicting the resulting remnant masses …
