Inertial Dynamics Of Non-Spherical Particles In Fluid Flows, Takashi Yashiro

Theses, Dissertations and Culminating Projects

We investigate the dynamics of small inertial spherical and non-spherical particles in fluid flows. We consider the Maxey-Riley-Gatignol (MRG) equation, which models well the motion of spherical inertial particles in low Reynolds number flows. To study how shape affects the dynamics, we implement a corrective factor on the Stokes drag term in the MRG equation. This corrective factor, or shape factor, is based on the geometric properties of the particles. The Basset-Boussinesq history term in the MRG equation is often neglected to simplify analytical and computational studies involving the equation. We include this history term and implement a multi-step integration …

Sample analysis consisted of physical and optical analysis as well as chemical analysis using SEM-EDS. Geochemical analysis using ICP-MS allowed for major, trace, and rare earth element concentrations of select …

Computational And Molecular Modeling Of Asphaltene Aggregation And The Effect Of Radicals And Nonradicals, Lyla Salyani

Theses, Dissertations and Culminating Projects

Asphaltenes are the heaviest component of crude oil consisting of a wide range of polyaromatic compounds with molar mass in the range of 500-800 g/mol. Asphaltenes tend to aggregate and form nanoclusters which lead to clogged pipelines. Understanding asphaltene aggregation has been a long-standing effort of industry and academia. Such systems are a typical example of systems studied to understand the impact of non-covalent interactions that drive the aggregation. Interactions that can be found to contribute to the stability of these aggregates can be π-π stacking, dispersion forces, and pancake stacking. A small fraction, 3%-4%, of the asphaltenes exist as …

Bounded Multiplication And Composition Operators On Sequence Besov Spaces, Robert Anderson

Mathematical Sciences Undergraduate Honors Theses

The sequence Besov space $b_p$, $p>1$, is the space of analytic functions $f(z)=\sum_{n=0}^{\infty} a_n\, z^n$ on the open unit disk

$\mathbb D$ with $$\sum_{n=0}^{\infty} n^{p-1}\, |a_n|^p< \infty\, .$$

We will give a brief introduction to the space $b_p$, as well as explore how certain operators behave on the space. For example, let $\varphi$ be an analytic self-map of $\mathbb D$. We study the multiplication operator $M_\varphi$ on $b_p$ and look at examples including when $\varphi$ is a polynomial. We also study the composition operator $C_\varphi$ on $b_p$, and in more depth on $b_2$ the Dirichlet space. The culmination will be an …

A Full System Co-Simulation Platform For Evaluating Edge Machine Learning Inference Using Compute-In-Memory, Belsen Lee

Electrical Engineering and Computer Science (MS) Theses

We present a full-system co-simulation platform for evaluating embedded machine learning (ML) inference using compute-in-memory (CIM). CIM architectures aim to reduce data movement overhead by performing matrix operations in memory, but end-to-end benefits depend on system-level integration costs that are difficult to assess with isolated hardware models alone. To address this gap, we develop an integrated RISC-V QEMU-SystemC co-simulation environment that allows standard embedded Linux to interact with a transaction-level CIM accelerator model via memory-mapped I/O, direct memory access (DMA), and interrupts. To evaluate performance, we benchmark an MNIST image inference workload and a synthetic fully connected neural network, comparing …

Computationally Probing Quantum Subgroups Via Graph Planar Algebra Embeddings, Caleb Kennedy Hill

Doctoral Dissertations

Tensor categories are algebraic objects used by physicists to describe symmetry, by computer scientists to describe programs, and by logicians to describe theorem and proof. Mathematicians invented them to capture the similarities of the representation theories of common algebraic objects including groups, algebras, and Lie algebras. In this dissertation we give presentations in terms of graphical generators and relations for two tensor categories arising from the two quantum subgroups of quantum G2.

We accomplish this by embedding a tensor-generating object's planar algebra into the graph planar algebra on that object's module fusion graph. Such an embedding allows one to explore …

Permeability And Mechanical Response Of Propped Fractured Rocks Under Varied Fluid Viscosities, Hebatalla A. Ghoneim

Doctoral Dissertations

Hydraulic fracturing relies on proppants to preserve fracture conductivity under reservoir stresses. The long-term performance of propped fractures is influenced by grain crushing, redistribution of fines, pack rearrangement, proppant–rock embedment, and shear deformation. These mechanisms are not fully understood under combined compression and shear stress paths, particularly when viscous carrier fluids interact with fractured rock and proppant packs. This dissertation provides experimental data and device development to characterize proppant and rock behavior relevant to these coupled mechanical and hydraulic processes.Proppant grain-scale strength and pack-scale mechanical response were first examined through uniaxial grain tests, crushing tests, and drained and undrained triaxial …

Leveraging Dna Intercalation For The Development Of Tunable, Versatile Supramolecular Hydrogels, Shaina Marlene Hughes

Doctoral Dissertations

Supramolecular hydrogels have emerged as a versatile class of biomaterials capable of mimicking the dynamic behavior of natural tissues due to their inherent hydrophilicity, stimuli-responsiveness, and viscoelastic behavior. However, achieving both biocompatibility and mechanical tunability remains a challenge. This work utilizes DNA intercalation to create a programmable, sustainable hydrogel platform. By utilizing the reversible insertion of planar aromatic molecules between DNA base pairs, we demonstrate that the network’s dissociation kinetics and thermodynamic response are directly governed by the intercalator structure, offering a highly tunable strategy for stimuli-responsive biomaterials.To demonstrate the versatility of double stranded DNA (dsDNA) intercalating supramolecular hydrogels (DISHs), …

Certain Hidden Stabilities Of Continued Fraction Arithmetic, With Applications To Classical Constants And Functions Of Analysis, Qian Hu

Doctoral Dissertations

We establish a hidden stability in the continued fraction expansions of certain real sequences. Classical theory predicts only statistical regularities for the partial quotients of actually random sequences, and repeated applications of the Gauss map would seem to have a randomizing effect even on analytically defined sequences; nevertheless we show how partial quotients connected to sequences governed by asymptotic expansions with rational coefficients always display a certain kind of periodic regularity and, upon taking closures, also an unexpected topological character. Our story connects three types of related data: sequences of real numbers, sequences of continued fraction expansions, and formal Laurent …

Who Works From Home, What Is It Worth, And Where Do They Live? Occupational Classification, Work Arrangement Preferences, And Residential Location Choice, Logan Robert Malone

Doctoral Dissertations

This dissertation examines work-from-home (WFH) arrangements through three complementary lenses: occupational feasibility, worker preferences, and residential location choice. The first chapter develops a continuous tools-based measure of WFH potential using the Department of Labor's O*NET Tools and Technology Supplement, which documents the tools used in each occupation. By categorizing tools according to their consistency with remote work and aggregating to the occupation level, I construct a measure that closely aligns with existing classifications while offering finer-grained distinctions than the binary categorizations common in the literature. The tools-based measure agrees with a widely cited task-based measure for approximately 80% of occupations …

Expanding The Vocabulary Of Staff Notation By Notating The Vocal Instrument, Ryan J. Berry

Honors Theses

The aspects of vocal music performance that are often the most engaging, expressive, and creative cannot be conveyed with the established vocabulary of staff notation. Consequently, discussion of artistic choices is limited to oral or written-word formats that are neither internationally interpretable or widely shared. This research proposes a remedy by creating notation symbols for the larynx, tongue, and formants so the movements of a singer's instrument can be described in staff notation. These symbols, along with the International Phonetic Alphabet, were applied to four performances to highlight specific artistic choices. Additionally, this paper discusses the history of vocal sheet …

Community Resilience And Response To Salinity Gradients In Streams Flowing Into Biscayne Bay, Florida, Sebastian M. Jimenez

Honors Theses

Salinity is a shaping force of aquatic biodiversity, and ongoing climate change and unsustainable water-management practices are causing salinity-induced stress across coastal ecosystems. Meiofauna are small (45-1000 μm), taxonomically diverse aquatic invertebrates that are vital to ecosystems and highly responsive to environmental disturbances, making them ideal for assessing the effects of changing salinities on community structure. This study investigated how meiofaunal biodiversity (ASV richness, Faith’s phylogenetic diversity, and community composition) responded to natural salinity gradients along streams flowing into Biscayne Bay, South Florida, which is a region particularly vulnerable to salinization due to sea-level rise, altered hydrology, and watershed modification. …

Improving Learning Habits In High School Ela, Alexander Sinn

Masters Projects

Students lack the habits and skills to process and apply what they have learned. In their secondary education, they are not developing the traits that help them succeed in college courses. Students are not explicitly taught note-taking and other study skills needed to succeed in core academic areas, English Language Arts (ELA) in particular. To address the needs of students, curriculum must incorporate expectations for students in self-efficacy and self-regulatory areas of learning. In the secondary ELA classroom, students should be provided opportunities and experiences to develop good habits. These should be requirements of 9th and 10th grade curriculum. The …

Bottles, Butterflies, And Biomass: Recycled Glass Sand, Microbial Additions, And Herbivory Effects On Milkweed Growth, Kealey Skinner

Honors Theses

Plant-soil-microbe interactions are integral components of ecological networks and drive ecosystem function from the bottom-up. Whereas herbivores regulate ecosystem function from the top-down, having opposing and potentially complementary effects on ecosystem function. My thesis sought to understand how below-ground microbial communities contribute to herbivore preference and plant biomass across varied soil substrates. My thesis asked: how do substrate and soil microbial communities influence herbivore preference and plant biomass accumulation on swamp milkweed (Asclepias incarnata)? To address this question, seedlings of A. incarnata were sown in 2.5 cm wide × 10 cm deep pots filled with either natural beach sand or …

Transformer Vulnerability To Geomagnetically Induced Currents Using Layered Soil Conductivity Models, Junior A. Sterling

Masters Theses

Geomagnetically induced currents (GICs) pose a significant threat to modern power transformers connected to long high-voltage transmission systems, particularly in regions with low subsurface electrical conductivity. During geomagnetic disturbances (GMDs), time-varying magnetic fields induce surface electric fields that drive quasi-DC currents through grounded transformer neutrals. These currents can bias transformer cores, leading to saturation, waveform distortion, and potential system instability. Despite extensive research, the role of regional Earth conductivity in shaping electric fields and transformer response remains an area requiring deeper investigation.

This study analyzes how contrasting Earth conductivity profiles influence GIC magnitude and transformer saturation risk using two representative …

Separating And Identifying Delta-8-Thc And Delta-9-Thc On Gc/Ms, Ann Schmidt

Honors Projects

Delta-8-THC and delta-9-THC are two psychoactive compounds found in marijuana products which are only distinguishable from each other by alternating the location of a single double bond.  This makes them a challenge to separate and identify as different compounds using the GC/MS.  These isomers are legally recognized as the different compounds, so being able to identify delta-8 and delta-9 THC separately is crucial to forensic analysis. The goal of this research project is to optimize an Intuvo 9000 GC connected to a standard MS to be able to separately and prominently identify delta-8-THC and delta-9-THC in a sample.  This was …

Taking A Deeper Look: Attributing Tonal Values Of Photolumens To Their Emulsions Using Scanning Electron Microscopy, Anna M. Moore

All Theses

This thesis examines whether tonal variation in photolumens made with historic silver gelatin photographic papers can be linked to differences in elemental composition. Photolumens are cameraless photographic images created by placing objects directly on light-sensitive paper and exposing them to ultraviolet light. Because expired and historic darkroom papers often produce unpredictable colors and tones, this study asks whether visually defined tonal groups also show measurable chemical differences.

Twenty historic paper samples were exposed, documented, and sorted into five tonal groups based on visible image characteristics. Each sample was then analyzed using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) …

This study examines soil properties in push-pull and conventional non-push-pull cropping systems. Soil samples were collected from push-pull and conventional plots in Ethiopia, Kenya, Rwanda, and Uganda. We examined the associations between soil physicochemical properties and cropping systems, along with key components of push-pull, namely Desmodium coverage and plot age, and manure and mineral fertiliser application. Overall, there were a few differences in soil …

Reflections On The Use And Misuse Of Economic Analysis In Copyright, Glynn Lunney

Faculty Scholarship

Economic analysis has long been used to justify copyright regulation. Long before the Statute of Anne, the Stationer’s Guild told the story of the copying competitor, who in the absence of regulation, would copy every original book and offer it for less. In the story, the coping competitor would, in the absence of regulation, deprive the original author of an opportunity to recoup their authorship investment, and so lead to a world where no books at all would be published. To ensure sufficient incentives for authorship, some degree of copyright regulation was thought essential. At the same time, in the …
