Exploring Integrated Arts Education For Students With Autism, Karen Denise Harrison

Electronic Theses and Dissertations

Students with autism spectrum disorder (ASD) are often misunderstood because of challenges in communication, social-emotional development, and sensory processing. Neuroscience research highlights that individuals with ASD process information and stimuli differently, particularly in areas related to sensory integration, executive functioning, and emotional regulation. Traditional educational methods often isolate these students from their neurotypical peers, reducing opportunities to engage meaningfully with standards-based curricula. Integrated arts education offers an alternative approach, aligning with neuroscience principles by engaging multiple brain regions through movement, rhythm, imagery, and creativity, allowing students with ASD to demonstrate their learning through project-based and creative experiences that meet diverse …

Kairosformer: Hybrid Transformer For Time Series Forecasting, Koichi Nishida

Electronic Theses and Dissertations

Long-term time-series forecasting is a fundamental problem in real-world applications such as financial modeling and weather forecasting. While Transformer-based architectures have shown strong performance in sequence modeling like natural language processing and computer vision, their direct application to time-series forecasting faces challenges including quadratic computational complexity and capturing inherent temporal dependencies. Recent works such as Informer and Autoformer address these limitations through sparse attention mechanisms and series decomposition, but introduce trade-offs between predictive accuracy and computational efficiency.

In this thesis, we propose Kairosformer, a Transformer-based architecture for long-horizon time-series forecasting that integrates probabilistic attention with series-wise temporal aggregation. By combining …

Adversarial Llm-Gans For Robust Synthetic Pharmaceutical Data In Self-Emulsifying Drug Delivery Systems, Samiul Islam Niloy

A Generalization Of Plane Partitions And Approximations Of The Resulting Function, Annette Jeanine Shinn

Electronic Theses and Dissertations

This dissertation is a generalization of two results which involve finding approximations of partition functions. The first is by Ayla Gafni in 2016, who found an approximation for the number of ways to partition a number n into k-th powers. The second is by E. M. Wright in 1931, who found an approximation for plane partitions. We look at a generalized partition function pk1,k2(n) that includes both cases and find an approximation for pk1,k2(n).

Three Implications For Leibniz’S Principle Of Sufficient Reason, Josiah Omiecinski

Electronic Theses and Dissertations

The Principle of Sufficient Reason (PSR) states that for everything that is the case, there is a reason for it being the case. The PSR has been a widely used principle in philosophy dating back to Parmenides (~500 BCE). While many philosophers are commonly associated with the PSR, none are as strongly associated with it than Gottfried Wilhelm Leibniz. This paper derives three surprising implications for Leibniz’s PSR from Leibniz’s claim that God, an unlimited mind, does not engage in reasoning while limited minds, like humans, do engage in reasoning. The implications are: A distinction between the PSR qua a …

Hereditary Transmission Of Drumming Among The Anlo-Ewe: The Case Of Agbodo/Amuzu Family Of Hatsukorfe, Denu, Volta Region, Ghana, Ernest Elikplim Kwabla Adonoo

Electronic Theses and Dissertations

This study examines the hereditary transmission of drumming among the Anlo-Ewe of southeastern Ghana, focusing on the Agbodo/Amuzu family of Hatsuk?ƒe in the Volta Region. Situated within ethnomusicological discourse on traditional Anlo-Ewe musical practices and the specialized roles of the researched family, who are drummers of the exclusive Ye?e religious tradition, this research argues that drumming in this context is not merely a musical activity but a complex system of communication, identity, ritual authority, and cultural continuity. The study fills and addresses a significant gap in existing scholarship on the Anlo-Ewe music, which has largely emphasized community dance-drumming and institutional …

Study Of Dynamics Of Airflow And Aerosol Transport And Deposition In Human Upper Airways Using Large-Eddy Simulations, Jacob C. Pratt

Masters Theses and Doctoral Dissertations

This study employs a large-eddy simulation (LES) strategy to investigate airflow and aerosol dynamics in the human upper airways using a truncated SimInhale configuration. Inflow conditions include three steady inhalation flow rates (14.2, 53.2, and 71 L/min), representing quasi-laminar, moderate, and high turbulence conditions, and a realistic cyclic breathing scenario. Under steady flow, monodisperse (1–10 μm) and polydisperse aerosols are analyzed. The study shows that complex airflow dynamics directly influence aerosol transport and deposition, causing global deposition to increase nonlinearly with particle size and Reynolds number, with the larynx being a primary deposition location in turbulent cases. For the polydisperse …

Characteristics Of Flame-Turbulence Interactions In Freely Propagating Turbulent Premixed Flames Under Decaying And Forced Isotropic Turbulence Conditions, Robert Smith

Masters Theses and Doctoral Dissertations

Turbulent premixed flames observed in energy conversion and propulsion applications are characterized by highly nonlinear, unsteady, and multi-scale processes. Previous numerical studies of freely propagating flames have utilized either forced or decaying background isotropic turbulence to provide detailed insights into the features of flame-turbulence interactions; however, none have made direct comparisons of cases where the turbulence decays or is sustained using a forcing strategy. This study compares the features of turbulent premixed flames via direct numerical simulations, where we consider both decaying and forced turbulence scenarios. Four turbulent premixed flames are simulated, corresponding to the thin reaction zone and broken/distributed …

Bounding The Average Kissing Number, Including New Bounds For Three-Dimensional Binary Sphere Packings, Mark William Bockhaus

Theses and Dissertations

The average kissing number is defined as the supremum over all sphere packings of the value: two times the number of tangencies divided by the number balls in the packing. In this paper, we present a survey of the literature about bounding the average kissing number, beginning with the first non-trivial results, through the most up-to-date bounds. We then turn our focus to binary sphere packings: those which contain spheres of two different radii. We improve upon known bounds for the average kissing number for binary sphere packings in three-dimensions and find exact bounds for many packings.

Assessing Water Quality And Nitrogen Dynamics In Bahia Grande, Texas Using Field And Remote Sensing Data, Sk Taufiqul Islam

Theses and Dissertations

An 8,220-acre estuary in South Texas, Bahia Grande has recently been restored from a disconnected hypersaline basin to a tidal estuary. A spatially explicit water quality index (WQI) was developed and in situ physicochemical data coupled with remote sensing data from Sentinel-2 were used to determine ecological integrity. A WQI from 29.45-53.20 yielded a spatial distribution of water quality that displayed a non-linear spatial trend throughout the estuary. Water quality close to the Brownsville Ship Channel inlet yielded values of 'Moderate/Stressed' water quality (> 50). These areas represent local zones of disturbance where ammonium concentrations were more than 11 µmol/L. …

Bayesian Change-Point Detection In Stock And Cryptocurrency Markets Using Shrinkage Priors, Yosalin Sanchez

Theses and Dissertations

Financial markets often undergo abrupt structural changes driven by political, economic, and geopolitical events, leading to substantial volatility. Detecting such change-points is crucial for identifying structural breaks, improving risk management, and enhancing forecasting performance in financial time series. This study proposes a Bayesian change-point detection framework that incorporates both the t-shrinkage prior and the Horseshoe shrinkage prior. These priors enforce strong regularization on successive differences in mean parameters, enabling the identification of piecewise constant structures in time series data. Posterior inference is conducted using Markov Chain Monte Carlo (MCMC) methods, specifically a Gibbs sampling algorithm, which iteratively samples from the …

Vision-Based Vibration Monitoring Of Civil Structural Damage Detection Using A Low-Cost Autonomous Uav, Javier Antonio Becerril

Theses and Dissertations

This thesis presents the development and experimental validation of a low-cost autonomous unmanned aerial vehicle (UAV) for non-contact vibration-based structural damage detection. We extract structural vibration signals directly from video recordings captured by the onboard camera during flight. The extracted vibration signals are analyzed in the frequency domain to identify natural frequency shifts associated with structural degradation and damage.

To evaluate the effectiveness of the proposed approach, a laboratory-scale steel frame structure is tested under both healthy and simulated damage conditions. In contrast to advanced commercial UAV inspection systems, the developed UAV achieves comparable inspection capability at a significantly lower …

Pesticides And Poverty: How Socioeconomic Factors Relate To Pesticide Application In The Continental Us, Reed Smetter

Theses and Dissertations

Pesticides are often used to help reduce the populations of weeds, insects, and pathogens in agricultural and urban settings, reducing the risk of outbreaks and losses of agricultural yield. The communities that surround agricultural areas often bear the brunt of the negative community and environmental health effects of these chemicals, and are frequently rural, poor, and lack critical infrastructure resources. Pesticide application volumes are often linked closely with specific health effects. In this study, I apply social vulnerability theory to compare the potential connections between the application rates of pesticides and socioeconomic variables across the United States using a nationwide …
