Application Of Reinforcement Learning To Precision Aerial Delivery System Control In Adverse Wind Conditions, Radman Zarbock

The Journal of Purdue Undergraduate Research

Precision aerial delivery systems (PADS) are a subset of airdropped parachute-leveraging package delivery systems that use autonomous guidance, navigation, and control (GNC) to reach targets with high degrees of accuracy. This technology emerged in the 1990s, and strides have been made since to improve the reliability of traditional physics-based controllers that guide PADS. However, these algorithms still struggle to deliver acceptable performance results when PADS are subjected to austere operating environments, such as those with unpredictable wind. Building on a foundational study in 2022 that used artificial intelligence (AI) and machine learning to improve PADS GNC performance, this study aims …

A Cave In Miocene Conglomerate: The Törökpince-Abaliget Cave System, Hungary, Krisztina Sebe, Piroska Pazonyi, Márton Bauer, Bálint Szappanos, Márton Szabó, Zoltán Szentesi, Mihály Gasparik, Ákos Juhász, Luca Pandolfi, Máté Gregorits, József Haász, Ágnes Novothny, Zsófia Ruszkiczay-Rüdiger

International Journal of Speleology

Conglomerate caves are rare, and only a few have been described in the scientific literature. Here, we present a newly discovered and significant cave system in SW Hungary, comprising over 500 m of upper passages and a shorter, lower section of a through-cave developed in Lower–Middle Miocene conglomerates. The formation of these cave passages was controlled chiefly by bedding and fractures. Dissolution has produced typical karstification morphologies, whereas corrasion, granular disintegration, and rock collapse have also played a role in shaping the cave. The cave is dominated by vadose-zone morphologies, but sediment infills indicating upward water flow, along with ceiling …

Confidence In The Pompeian Fullo, Tori Nielsen

Studia Antiqua

Many scholars have discussed a curious graffito parodying the Aeneid found outside of a Pompeian fullonica, but few have taken into account its visual and written context. I synthesize previous scholarship and consider additional neighboring graffiti and visual elements in order to more thoroughly reconstruct the ideas conveyed about fullers in this space. The outer wall celebrates fullers in cultural, social, and fulling matters, thus bolstering their community’s confidence in them.

Factors Affecting Risk Perceptions About The Human Health Effects Resulting From Harmful Algal Bloom Exposure, Alexandra Benitez Gonzalez, Heather A. Triezenberg, Diane Doberneck, Abigail Bennett, Mark Rey

Journal of Contemporary Water Research and Education

In the Great Lakes region, harmful algal blooms (HABs) are known cyanobacterial blooms that pose significant public health, environmental, and socio-economic risks. Risk information related to HABs is primarily communicated through state and local government agencies; however, the effectiveness of these communication strategies and how local stakeholders are learning about such risks remains unclear. The objective of this study is to examine how to effectively communicate HABs risks and understand public risk perceptions of HABs-related risks during recreational lake use in Michigan. Guided by the social amplification of risk framework, this qualitative study conducted fieldwork in 2021, including 27 semi-structured …

A Parallel Interval Modeling Framework For Nonlinear Systems: Application To A Modified Duffing Oscillator, Roman Voliansky, Nina Volianska

Northeast Journal of Complex Systems (NEJCS)

The paper presents a mathematical framework for converting nonlinear dynamical systems into parallel forms. This framework replaces the exact system motion equations with interval equations, enabling the representation of nonlinear functions over piecewise linear domains. Such representation enables the description of system motions using linear-like differential equations, which can be analyzed and manipulated using well-known control methods. One such method is eigenvalue analysis, a powerful tool in classical control theory since many techniques rely on the system’s characteristic polynomial and its eigenvalues. We apply this method to define interval system eigenvalues and track their variation during system operation. These eigenvalues …

Structural Framework And Tectonic Implications From Field Investigations In The Ramelau Mountains, Timor-Leste, Tanner A. Nielsen

Theses and Dissertations

Recent advances in petroleum exploration off the southern coast of Timor-Leste and emerging mineral discoveries onshore have underscored the need for a more comprehensive structural understanding of the nation's geology. Although new structural models have been proposed for other parts of Timor, limited progress has been made toward developing detailed models for the Ramelau Mountains, which presents the highest structural relief of the Timor Ranges. Previous mapping in this area has been largely reconnaissance in nature and focused primarily on surface bedrock geology. This study presents a new 1:62,500-scale geologic map and a geometric structural analysis of the Ramelau region …

If You Don’T Know, Now You Know: Jase Special Issue On Hip-Hop Pedagogy For Students With Disabilities (Side A), Jonte C. Taylor

Journal of the Arts and Special Education

This special issue examines Hip-Hop pedagogy (HHP) as a culturally grounded, multimodal approach that supports K–12 students with disabilities. Hip-Hop is presented as a comprehensive culture rooted in the five elements—MCing, DJing, breakdance, graffiti, and knowledge—which offer inclusive pathways for identity development, community, and learning. This special issue of JASE highlights HHP as an asset-based framework that enhances engagement, self-expression, assessment, and social-emotional growth while aligning with high-leverage practices. Research demonstrates that hip-hop–infused instruction can deepen academic understanding, reframe behavioral challenges, and promote equitable, disability-affirming learning environments. The included articles explore belonging for students who stutter, integrated pedagogical models, mentorship …

Keeping It Real: Hip-Hop Based Education In A Mathematics Classroom, Michelle J. Cook, Elizabeth M. Hughes, Jonte C. Taylor

Journal of the Arts and Special Education

Hip-Hop based education (HHBE) infuses elements of Hip-Hop culture into teaching and learning. Growing research shows that HHBE engages students, validates students’ identities and lived experiences, and supports academic success. In this article we share how HHBE can be used in mathematics with a focus on teaching word problem solving strategies. Using vignettes and real-life examples, we illustrate how creative elements of Hip-Hop (i.e., breakdancing, graffiti art, DJing, MCing, knowledge of self) naturally enhance mathematics and word-problem solving instruction. Educators can sample/adapt strategies shared to create HHBE lessons to meet the interests of their students with disabilities. We hope that …

Astronomy: Faculty Publications

Investigating the processes by which galaxies rapidly build up their stellar mass during the peak of their star formation (z  =  2–3) is crucial to advancing our understanding of the assembly of large-scale structures. We report the discovery of one of the most gas- and dust-rich protocluster core candidates, PJ0846+15 (J0846), from the Planck All-Sky Survey to Analyze Gravitationally lensed Extreme Starbursts (PASSAGES) sample. The exceedingly high total star formation rate (SFR) uncorrected for lensing magnification ( μ) of  μSFR  yr−1 is the result of a foreground cluster lensing at least 11 dusty star-forming galaxies between z …

Learning From Images And Text (Clinical) Data: Toward Putting Ai In Radiology Workflows, Pan Xiao

McKelvey School of Engineering Graduate Student Theses & Dissertations

The rapid growth of medical imaging data highlights the need for intelligent systems that can understand both radiological language and image content. This dissertation presents two complementary research directions that advance machine learning in radiology through large-scale natural language understanding and unsupervised image representation learning. The first part develops and benchmarks machine learning models for identifying follow-up recommendations in radiology reports—a task essential for improving patient care and reducing missed follow-ups. Using 49,769 reports across multiple modalities and three institutional datasets, along with external and temporal test sets, thirty-two classification methods were systematically evaluated on both findings and impression sections. …

Exploring The Potential Effects Of Read Naturally Live To Support Reading Fluency Development In Diverse Learners, Jovonne Tabb

Electronic Theses and Dissertations

The ability to comprehend and apply knowledge learned through reading is fundamental for individuals to become successful and productive citizens in society. The inability to read fluently and accurately with appropriate pacing and expression significantly inhibits text comprehension. Research suggests that children who do not develop reading fluency are more likely to experience learning and comprehension difficulties throughout their academic careers (Lange, 2019). Computer-assisted interventions (CAI) have demonstrated effectiveness in advancing students' reading fluency, particularly for those at risk of developing reading disabilities or those already diagnosed with reading difficulties. However, a significant gap exists in research examining CAI effectiveness …

Discovery Of The Multi-Ion Bridge Intermediate: A Computational Exploration Of The Mechanism For Azomethine Ylide Formation From N-Oxides, Martin J. Neal

Electronic Theses and Dissertations

Density functional theory (DFT) provides a method for calculating the ground-state energies of complex molecular systems through evaluating the electron density instead of the full wave function. When results match either experimental outcomes, calculations with DFT offer a computationally efficient method to help explain chemical phenomena. The transformation of tertiary amine N-oxides to azomethine ylides, a simple route to the precursor for 1,3-dipolar cycloadditions that result in the pyrrolidine scaffolds found in natural products, has received only minimal attention due to concerns that its mechanism includes a highly electrophilic intermediate. Utilizing DFT to model the mechanism of the conversion …

Limiting A Liberal Education: Exploring Technology Access And Equity Through Universal Design And Critical Disability Studies, Marisa R. Carlson

Electronic Theses and Dissertations

This quantitative improvement study investigates how classroom technology policies impact equity, access, and alignment with liberal arts values at a small Catholic liberal arts college. The study arose from concerns regarding academic accommodations, where students needed to formally request access to digital tools that were widely available. The focus is on inconsistent and sometimes restrictive technology policies that create barriers for students relying on these resources.

Interpreted through the conceptual frameworks of Universal Design for Learning (UDL) and Critical Disability Studies (CDS), this study was guided by the following research questions:

1. What expectations do students have regarding access to technology …

I Am Mentorship: Hip-Hop As A Mirror For Belonging And Becoming, David J. Berg

Journal of the Arts and Special Education

This paper presents MENTEE-SS (Mentorship, Engagement, Nurturing, Trust, Empowerment, Excellence-Systems of Support for Students and Families), a practitioner-focused reimagination of Multi-Tiered Systems of Support (MTSS) through the lens of hip-hop pedagogy, mentorship, and culturally sustaining practices. While traditional MTSS frameworks often emphasize compliance and deficit-based intervention, MENTEE-SS situates support in student identity, creativity, and voice.

Grounded in relational trust and arts integration, the framework uses the author’s original song I’M HIM as a case study in identity reclamation. Three tiers bring this vision to life: co-designed classroom rituals (Yo DJ, Spin That Class!, Tier 1), lyric-writing groups for recovery (The …

Nontoxic Paints Using Cornstarch As Binders, Maile Prater

Honors Projects

For this project, paints were created using different metal compounds which interacted with cornstarch and pectin to determine whether the metals would coordinate with these polysaccharides to create new types of watercolor paints. The paints that were created were ran through an RGB analysis to determine how much of each RGB color is present in a solution and then were ran through a rheometer to determine how the viscosity differed between each solution.
