Local Existence for a Non-local Multi-Species Advection-Diffusion Equation with Newtonian Potential

Creator:

Radke, Zachary

Abstract:

In biological models, advection is inherently a non-local process. Coupled with diffusion, it typically models chemotaxis, which is the response of bacteria to the presence of some chemo attractant. For example, E. coli cells use their flagella to probe their surroundings to determine where they should move. The advection-diffusion equation...

Masters Thesis
Operator Splitting for a Wildfire Model in a Heterogeneous Environment with a Surrogate Wind Velocity Field

Creator:

Pantuso, Nicholas M.

Abstract:

Living in the Pacific Northwest, we are acutely aware of the dangers posed by wildfires. Largely due to the worsening effects of climate change, this danger is only increasing. Along with causing property and economic damage to those communities affected by wildfires, exposure to the smoke generated by wildfires can...

Modelling Development of Opinion Matrices Over Time

Creator:

Oostrom, Martijn L.

Abstract:

Given an initial opinion matrix in which every member of a population gives an opinion score of all the members in a population, natural questions to ask could be regarding what happens to those opinions over time, both in forward time and in backward time. While what happens over time...

Teaching Mathematics to International Students in Higher Education

Creator:

Valenciano, Julissa C.

Abstract:

Institutions of higher education have experienced a rapid increase in international student enrollment within a short period of time, especially in mathematics classrooms. It is therefore important for instructors to have the knowledge and skills to support international students in the learning of mathematics. There are few research studies of...

Masters Thesis
Instructors’ Perspectives and Practices of Equity and Inclusion in Post-Secondary Mathematics

Creator:

Scarborough, Melissa

Abstract:

There is an underrepresentation of minority groups and women in the field of mathematics. With growing interest in equity and inclusion within the mathematics education community, it is important to look at how such concepts can be implemented in the classroom. Equitable and inclusive teaching practices have been shown to...

Masters Thesis
Stability Analysis of Coupled Discrete Time Systems On an Invariant Cone

Creator:

Fletcher, Sally

Abstract:

This paper concerns a question that frequently occurs in various applications: Is any dispersal coupling of stable discrete linear systems, also stable? Although it has been known this is not the case, we shall identify a reasonably diverse class of systems for which it is true. We shall employ the...

Reynolds Stress Tensor Systems and Applications to Nonuniqueness of Weak Solutions to Fluid

Creator:

Donaghue, Patrick E.

Abstract:

In the 1954 John Nash [1] showed, through use of an iterative scheme of approximate embedding maps, that the sphere S² could be isometrically embedded into a ball of any radius by a C¹ map. In the 1980's M. Gromov [2] generalized Nash's work to the h-principal and convex integration....

The Experiences of Women in First-Term Calculus: Factors Affecting Mathematical Confidence

Creator:

Petty Blaisdell, Amanda

Abstract:

As industries relating to science, technology, engineering, and mathematics in America continue to grow, employers will need more mathematicians and mathematically able workers than are currently graduating. Women are an underrepresented portion of these graduates, and researches say that this could be due to the difference between women’s and men’s...

Numerical Study of Convexity Splitting Scheme for Coupled Phase Field and Stefan Free Boundary Problems

Creator:

Bigler, Lisa A.

Abstract:

In this work, we consider a convexity splitting scheme for a coupled phase field and energy equation, a modification of Stefan problem. The Stefan problem is a free boundary value problem that models the temperature in a homogeneous multiphase medium. Each phase is modeled using a heat diffusion parabolic partial...

Masters Thesis
A Homotopy Strategy for Accelerated Sampling

Creator:

Jensen, Andrew D.

Abstract:

Markov Chain Monte Carlo methods may be used to determine normalizations and moments of distributions. However, these methods may perform poorly when starting from distributions that have little overlap with the target. We develop a homotopy based iterative process of incremental importance sampling to normalize distributions when observations can only...
