Alignment data were recorded using a spreadsheet-based content analysis and independently coded to support …

System Design And Validation Of Radio Astronomy Phased Arrays, Rebecca Shiu Haymore

Theses and Dissertations

Modern radio astronomy instruments require a wide field of view and high sensitivity. To this effect, BYU and Cornell University have developed the Advanced L-band Phased Array Camera for Astronomy (ALPACA), a fully cryogenic 69 dual-pol dipole array that produces 80 beams on the sky with 305 MHz instantaneous bandwidth centered on 1500 MHz. Integration testing has demonstrated proper beamforming and calibration, and ALPACA has been commissioned as an all-sky monitor to search for bright transients. Commissioning testing for ALPACA measured an element system noise temperature of 24 K and a beamformed system noise temperature of 17 K, making ALPACA …

Application Of Palmprint Data For Prediction Of Diabetes, Ramasamy K Mr

Theses and Dissertations

Type 2 diabetes is one among the diabetes mellitus which has strong relation with lifestyle, genetics and metabolic dysfunction. The increasing global prevalence, rising healthcare costs, and high percentage of undiagnosed individuals leads to the need of noninvasive, cost-effective early detection methods. In conventional diagnostic methods, laboratory investigations and periodic clinical visits are needed, which may not be feasible for working and middle-aged populations. To overcome this, the research work proposes an automatic, non-invasive and early prediction of Type 2 diabetes using palmprint image analysis integrated with clinical data for identifying diabetic and non-diabetic individuals. The first proposed method aims …

Radiation Effects On The Amd Versal Running An Automatic Modulation Classification Model, Allan D. Howe

Theses and Dissertations

With the recent increase of interest into artificial intelligence (AI), graphics processing units (GPUs) have been used as the main hardware architecture for AI computation. Because of their high power consumption and large size, it is necessary to consider other architectures to perform AI computing in outer-space where size, weight, power, and cost (SWaP-C) are tightly constrained. One such architecture is the Advanced Micro Devices (AMD) Versal Adaptive Compute Acceleration Platform (ACAP), which can achieve acceptable AI throughput at a lower power and size compared to a GPU. As the Versal ACAP gets used in space applications, it is necessary …

Equivocation Analysis Across Continuous And Discrete Memoryless Channels, Md Munibun Billah

Theses and Dissertations

Physical-layer security uses the noise already present in the channel to keep a message secret without making any assumption about the eavesdropper's computing power. In Wyner's wiretap channel model, coset coding uses randomness to map the message to many codewords and protects against information leakage from an active eavesdropper. The secrecy provided by such codes is measured by their equivocation, which is the eavesdropper's remaining uncertainty about the message after she observes her channel. So computing equivocation is an important aspect of analyzing the wiretap channel model. Many channels of practical interest have no closed-form expression for equivocation, and exact …

Development Of Novel Plasminogen Activators From Fragments Of Streptokinase Enzyme, Vijay G Mr

Theses and Dissertations

Thrombotic disorders such as myocardial infarction, ischemic stroke, pulmonary embolism and deep vein thrombosis remain major causes of mortality and disability worldwide, creating a continuing need for effective, safe and affordable thrombolytic therapy. Streptokinase is one of the most widely used plasminogen activators because of its activity, low cost and broad availability. However, its wider clinical utility is limited by high immunogenicity, allergic reactions, neutralizing antibody formation and poor suitability for repeat administration. This thesis aimed to develop novel streptokinase-derived plasminogen activators by identifying smaller functional fragments that retain thrombolytic activity while potentially reducing immunogenicity.

A literature-guided fragment-based strategy was …

Optical Integrated Sensing And Communication: Deep Reinforcement Learning-Based Beam Tracking For Dynamic Vehicle-To-Everything Networks, Akshat Sharan

Theses and Dissertations

Optical Wireless Communication (OWC) promises ultra-high bandwidth for vehicular networks but suffers from critical beam misalignment in dynamic environments. The emerging paradigm of Optical Integrated Sensing and Communication (O-ISAC) addresses this challenge by unifying the sensing and communication functions over a single shared optical aperture, enabling real-time environmental awareness to guide beam steering. However, the multi-objective, stochastic nature of this joint optimization problem renders classical closed-form controllers inadequate. This thesis proposes and evaluates a deep reinforcement learning framework for continuous beam tracking in a 2D vehicular O-ISAC scenario. We conduct a comprehensive comparative study of four state-of-the-art deep RL algorithms: …

From Compliance To Inclusion Through Collaborative Action Research (Car): Service-Animal Access In Experiential Settings In Higher Education, Allison Christina Gainer

Theses and Dissertations

Experiential learning is essential for degree completion, licensure, and professional preparation, although access to service animals in practical contexts is often ambiguous and inconsistently implemented. This study examined the disconnect between legal access protections and institutional practices in real-time access decisions driven by safety, program integrity, accrediting standards, and decentralized decision-making. The purpose of this qualitative Collaborative Action Research (CAR) study was to examine Rowan University’s understanding, interpretation, and implementation of service animal regulations and procedures and to suggest alternatives for legal and equitable access. The study was based on the social model of disability and used four CAR cycles. …

Identifying Failure Behaviors In Stereolithography From Varied Print Orientations, Kevin Veltre

Theses and Dissertations

Stereolithography (SLA) is an additive manufacturing (AM) technique that utilizes photopolymerization to create three-dimensional shapes by strategically printing layers of material. Printing parameters such as layer orientation, print resolution and post cure can affect a specimen’s homogeneity, longevity and mechanical characteristics. Because of this variability, print parameters must be carefully considered when designing products and print processes for desired components, as manufacturers often fail to include all relevant print settings when advertising mechanical properties. For this study, 130 SLA-printed specimens were created with 100-micron print layer thickness and print orientations varying between 0 and 90, including intermediate orientations, to observe …

Common challenges include infrastructure limitations, teacher preparedness, and institutional support. The second study adapts …

Developing An Understanding Of Concavity Built On Covariation, Jade E. Gregg

Theses and Dissertations

This study investigated how six students developed a quantitative understanding of concavity founded in covariational reasoning through a series of task-based teaching interviews. A key finding was the importance of multivariational reasoning--the coordination of more than two variables--in helping students reason deeply about concavity in context. Common difficulties, including confusion about negative rates and overreliance on visual representations, served as productive opportunities for learning when addressed through carefully designed tasks and discussions. The findings extend existing frameworks of covariational reasoning and highlight instructional approaches that can support students in developing a robust, quantity-based understanding of concavity.

This paper will examine four case studies of different collisions that have similar circumstances to the Francis Scott Key Bridge collapse and review National Transportation Safety Board reports …

Fatigue And Healing Performance Of Asphalt Materials Modified With Nanomaterials And High-Polymer Asphalt Binders, Samuel M. Addai

Theses and Dissertations

Fatigue cracking is one of the primary distress mechanisms affecting asphalt pavement durability under repeated traffic loading and environmental aging. Although asphalt binders possess an inherent ability to heal micro-damage during rest periods, this healing capacity is often insufficient to fully counter progressive fatigue damage under field conditions. This thesis investigates the fatigue and self-healing behavior of asphalt binders and mixtures modified with nanomaterials and advanced polymer-based systems. Nanomodified binders were evaluated using Linear Amplitude Sweep (LAS) and Linear Amplitude Sweep with Healing (LASH) tests within the VECD framework to quantify fatigue resistance and healing behavior under different rest periods …

Fraud And Focus: Examining Self-Control Strategies In Students Experiencing Impostor Phenomenon, Francesca Angela Catalano

Theses and Dissertations

Impostor phenomenon (IP) is a common experience among individuals in achievement contexts characterized largely by feelings of self-doubt, attributions of success that focus on external factors, and beliefs that one is “fooling” others about their competence. Current research suggests the effects of IP are complex (e.g., IP is associated with higher grade point average and productivity but also self-handicapping, psychological distress, and difficulties adjusting to college). To better understand these complex effects, this study proposes a self-control perspective for IP, where this phenomenon is seen as involving additional self-control burdens. Specifically, the study examines whether IP is associated with grade …

Multidisciplinary Inverse Robust Co-Design Of Materials, Products, And Manufacturing Processes, H M Dilshad Alam Digonta

Theses and Dissertations

Realizing the design for Integrated Computational Materials Engineering (ICME) requires the materials, product, and manufacturing-process disciplines to be designed together. Because these disciplines interact and influence one another's decisions, coordination is needed among their distributed decision-makers. Their interactions are captured through the processing-structure-property-performance (PSPP) linkages, which must be established from limited, costly data. Moreover, each discipline introduces its own sources of uncertainty, and these propagate through the process chain to influence final product performance. The effective realization of the product-material-manufacturing system, therefore, calls for a co-design approach that enables the concurrent coordination of the interacting disciplines while quantifying and managing …

On The True Interstellar Anisotropy Of Tev Cosmic Rays And Its Implications For The Local Interstellar Medium, Noufel D. Maalal

Theses and Dissertations

Several ground-based cosmic ray (CR) air shower experiments have produced sky maps of intensity anisotropy in the energy range from 1 TeV to a few hundred TeVs with very high statistics and angular resolution. These measurements provide opportunities to study CR sources and propagation in the interstellar medium (ISM). Such studies present two major difficulties. Firstly, CRs are deflected by the heliospheric magnetic field on the last stretch of their journey to Earth. Secondly, measurements at different latitudes are difficult to compare, leading to uncertainties in latitudinal variations on the order of the observed anisotropy. Experiments usually assume latitudinal variations …

Grit, Self-Assessment, And Second Language Proficiency: A Large-Scale Examination Using Data From The Language Ability Self-Evaluation Resource, Andrew T. Skoy

Theses and Dissertations

Grit has been defined as being "perseverance and passion for long-term goals" (Duckworth et al., 2007). Research has tied grit to success in the discipline of second language acquisition (SLA), where researchers have adapted Duckworth's general grit self-assessment instrument to capture measurements of grit within second language learners (Teimouri et al., 2022). Such a scale appears on the Language Ability Self-Evaluation Resource (LASER), a standardized language proficiency test developed by researcher at Brigham Young University. With the aim of replicating the studies that were done to validate the design of the LASER, responses to the grit-measuring section of the test …

FSP was successfully completed on high-carbon ASTM F1537 CoCrMo plates with operating temperatures ranging from 630°C to 850°C by adjusting spindle speed, traverse speed, and forge force. Hardness, wear resistance, and corrosion resistance testing were performed, along with Electron Backscatter Diffraction (EBSD) to analyze grain refinement and phase structure. FSP produced grain refinement up to 97% relative to the untreated baseline across the investigated temperature range, with lower processing temperatures …

A Holistic Framework For Enhancing Machine Learning Reliability: From Model Architecture And Algorithm Design To Human Interpretability, Kyle Naddeo

Theses and Dissertations

Modern machine learning systems can perform well on benchmarks yet fail in ways that are difficult for users to anticipate, interpret, or manage. This dissertation treats reliability as more than accuracy: a reliable system performs when it can, signals when it should not be trusted, and supports abstention, fallback, escalation, or human review. Unlike robustness, which emphasizes performance under shift, corruption, adversarial perturbation, or drift, reliability also requires recognizing limited competence, preserving useful semantic structure when fine-grained certainty is unjustified, and exposing mechanisms that make failures understandable. The dissertation develops this view through four contributions. Uncertainty-aware decision heads provide portable …

This work details advances in three essential areas on the path to that goal: data quality, activity prediction and modeling, and stability optimization. The structure and implementation of the Allotrope Simple Model (a FAIR data format for many scientific instruments) was examined in [2], setting the stage for training deep learning models on high-quality experimental datasets from diverse sources. In [3], the limits of physics-based and deep learning tools …

Beyond Single Images: A Comprehensive Benchmark For Album-Level Vision-Language Understanding, Shawn Huang

Theses and Dissertations

Automatic album organization has been studied extensively over the past decades due to significant progress in digital photography. Recent Vision-Language Models (VLMs) have shown strong performance on multi-image understanding, making them natural candidates for automating album organization workflows. While VLMs’ abilities in multi-image understanding have been widely studied, their performance on album organization remains underexplored. To bridge this gap, we introduce AlbumBench, the first comprehensive benchmark for automatic album organization. Specifically, we (1) define album organization tasks as photo selection for album-specific user objectives, photo rating according to how well user intents are fulfilled, and album-specific photo grouping given a …

Toward Passwordless Document Encryption, Isaac Henry Teuscher

Theses and Dissertations

Document files with sensitive information are used across nearly every industry. In recent years, cyberattacks targeting cloud-based file transfer applications have resulted in millions of sensitive documents being exposed. Although document encryption methods exist, they are often limited in usability, security, or deployability. Password-based encryption, the most widely available option, remains vulnerable to brute-force attacks, unauthorized sharing, and human error. We address these gaps in three phases. First, we present a structured comparative framework adapted from the usability-deployability-security model to evaluate nine document encryption methods across 15 design properties, identifying the benefits and limitations of current approaches. Second, we design …

I Will Defend My Self, Emily Ward Hawkins

Theses and Dissertations

This thesis examines caregiving and motherhood as forms of load-bearing infrastructure. Cultural narratives often portray motherhood through sentimental images of joy, tenderness, and devotion, obscuring the structural labor that sustains family life. This project examines maternal labor as a largely unseen system of support that organizes family life while often remaining backgrounded. Caregiving reorganizes time, space, ambition, embodiment, and future orientation within maternal life. Through sculptural works using architectural materials and construction systems, such as oriented strand board, blueprint racks, metal armatures, and graph paper, the project visualizes caregiving as a structural condition. These materials reference the language of architecture …
