The development of pre-service teachers' Technology Specific Pedagogy

Creator:

Harrington, Rachel A.

Abstract:

The purpose of this study was to document the development of pre-service teachers' Technology Specific Pedagogy as they learned to teach mathematics with technology during their initial licensure program. The study investigated the pre-service teachers' learning using both a social and a psychological perspective of teacher learning. Two research questions...

Dissertation
The structure of E6

Creator:

Wangberg, Aaron D.

Abstract:

A fundamental question related to any Lie algebra is to know its subalgebras. This is particularly true in the case of E6, an algebra which seems just large enough to contain the algebras which describe the fundamental forces in the Standard Model of particle physics. In this situation, the question...

Mixing time for a 3-cycle interacting particle system : a coupling approach

Creator:

Eves, Matthew Jasper

Abstract:

This thesis examines the mixing times for one-dimensional interacting particle systems. We use the coupling method to study the mixing rates for particle systems on the circle which move according to specific permutations e.g., transpositions and 3-cycles.

Masters Thesis
An intrinsic codimension two cellular decomposition of the Hilbert cube

Creator:

Ghimire, Kailash C.

Abstract:

Cellular sets in the Hilbert cube are the intersection of nested sequences of normal cubes. One way of getting cellular maps on the Hilbert cube is by decomposing the Hilbert cube into cellular sets and using a quotient map. By using a cellular decomposition of the Hilbert cube, an example...

Dissertation
Skew Brownian motion and branching processes applied to diffusion-advection in heterogenous media and fluid flow

Creator:

Ramirez, Jorge M.

Abstract:

This thesis contains three manuscripts addressing the application of stochastic processes to the analysis and solution of partial differential equations (PDEs) in mathematical physics. In the first manuscript, one dimensional diffusion and Burgers equation are considered. The Fourier transform of the solution to each PDE is represented as the expected...

Upscaling non-Darcy flow using mixed finite element method

Creator:

Garibotti, Cristiano Rodrigues

Abstract:

In this paper we develop an upscaling technique for non-Darcy flow in porous media. Non-Darcy model of flow applies to flow in porous media when large velocities occur. The well-posedness results for theory of quasilinear elliptic partial differential equations. To discretize the model we used lowest order Raviart-Thomas mixed finite...

Masters Thesis
Nonlinear solvers for a model problem of fluid flow in the subsurface

Creator:

Biederman, Shannon Miriah

Abstract:

Water is one of the most biologically and economically important substances on Earth. A significant portion of Earth's water subsists in the subsurface. Our ability to monitor the flow and transport of water and other fluids through this unseen environment is crucial for a myriad of reasons. One difficulty we...

Masters Thesis
Renewal risk processes with stochastic returns on investments : a unified approach and analysis of the ruin probabilities

Creator:

Constantinescu, Corina D.

Abstract:

This thesis considers one of the classical problems in the actuarial mathematics literature, the decay of the probability of ruin in the collective risk model. The claim number process N(t) is assumed to be a renewal process, the resulting model being referred as the Sparre Andersen risk model. The inter-claim...

Dissertation
Towards an analytical model for carbon storage in forested landscapes

Creator:

Ngo, Nam V.

Abstract:

An analytical model is developed to address the question of how different disturbance regimes affect the mean and variance of landscape carbon storage in forest ecosystems. Total landscape carbon is divided into five pools based on the processes from which they are derived and based on their temporal dynamics. Formulae...

Masters Thesis
Pushing into advanced mathematics classes: a grounded theory study of ability grouping in middle level mathematical classes

Creator:

Johnston, Tina Louise

Abstract:

The focus of this grounded theory research was to investigate the problems that those groups closest to students placed in mathematics classes by mathematics ability have and how those parties work to resolve the problems. The main problem found was a conflict between educators and parents over which students deserve...
