Mathematical Modeling, Analysis And Numerical Simulation Of Air Quality Using The Advection-Diffusion-Reaction Equation, Md Timorul Islam

Math Theses

In this thesis, we study an air quality model by using a nonlinear one-dimensional advection-diffusion-reaction system of partial differential equations for NO-NO2-O3 chemical cycle. The model incorporates advection, diffusion, chemical reactions, and source terms, and is formulated based on standard atmospheric chemistry.

We first develop numerical methods to approximate the solutions of the governing equations. Both explicit and implicit finite difference schemes are considered, and the implicit scheme provides approximations without any restrictions on the stability.

The model is then nondimensionalized to identify key parameter combinations governing the system. This leads us to a regime in which the transport and …

Three-Dimensional Imaging Of Neuronal Activation Patterns In Chronic Neuropathic Pain And Opioid Pharmacology, Madeline Martinez

Electronic Theses and Dissertations 2020 - Present

Chronic neuropathic pain severely diminishes quality of life, yet the supraspinal neural circuits that sustain pain perception and mediate analgesic relief remain incompletely characterized. While peripheral and spinal pain pathways are well established, relatively few studies have mapped pain- or opioid-related neuronal activation across the entire brain. This dissertation employed activity-dependent genetic labeling (TRAP2/Ai9), whole-brain tissue clearing, light sheet microscopy, and graph-theoretic network analysis to characterize brain-wide activation patterns across chronic pain and analgesic conditions in mice.

In Chapter 1, we mapped supraspinal neuronal activation in a bilateral spared nerve injury model of chronic neuropathic pain. Although no individual region …

On The Drainage Vortices Of Liquid In A Container With Two Outlets, Radivoje Stankovic

Electronic Theses and Dissertations 2020 - Present

Vortices that form over multiple drainage ports may exhibit a distinct, periodic alternating behavior, whereby the air core moves periodically between different drainage ports. The physical processes which govern this behavior have not yet been explained, despite the widespread and thorough attempts to describe the flow of water through single or multiple outlets. Early experiments on the alternating behavior of this vortex resulted in a nondimensional relation between the alternating frequency and water height and container geometry with an R2 = 0.91. Subsequent 2D PIV measurements of the flow were performed at different laser heights of 25 mm and 128 …

Testing Effects Of Acoustic Propagation, Morphology, And Intrasexual Selection On The Elaboration And Performance Of Song In Bachman’S Sparrows (Peucaea Aestivalis), Hans Kayser Gonzembach

Electronic Theses and Dissertations 2020 - Present

Birdsong is a communication signal shaped by ecological, morphological, and cultural processes. While many songbird species produce relatively simple vocal repertoires, others, such as the Bachman’s Sparrow (Peucaea aestivalis), produce moderately large repertoires with multiple distinct and context-dependent song categories. Despite this complexity, little is known about the major drivers that shape song elaboration in this species. Additionally, it is unclear whether abiotic factors play a significant role in determining how different song types are learned and shared within a population. To better understand how ecological and social pressures shape song variation, I conducted three studies using Bachman’s …
