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
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
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...

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
Analysis of fourth order numerical methods for the simulation of electromagnetic waves in dispersive media

Creator:

Henderson, Scott Edward

Abstract:

In this thesis, we investigate the problem of simulating Maxwell's equations in dispersive dielectric media. We begin by explaining the relevance of Maxwell's equations to 21st century problems. We also discuss the previous work on the numerical simulations of Maxwell's equations. Introductions to Maxwell's equations and the Yee finite difference...

Masters Thesis
The structure of preordered sets and their topological properties

Creator:

Bu, How-shone

Abstract:

Let X be a set. Given any preorder < on the set X, there corresponds a family of subsets of X, namely, WIx E x} where L = {y y E X y <x} such that, for all elements x and y of X, x <y iff L ( L....

A model of Non-Euclidean geometry in three dimensions, II

Creator:

Eschrich, Robert William

Abstract:

This paper is a continuation of William Zell's thesis, A Model of Non-Euclidean Geometry in Three Dimensions. The purpose of that thesis was to show that the axioms of non-Euclidèan geometry are consistent if Euclidean geometry an& hence arithrnetic is consistent. Mr. Zell. discussed the axioms of connection and order...

Risk Management for Nonprofit Organizations

Creator:

Chen, Li

Abstract:

We introduce a model for the surplus of nonprofit organizations (NPO). We assume two types of spending schemes for an NPO. Type I is a constant spending rate and Type II is a variable rate above and below a cut-off reserve level. Under steady state, we compute and compare the...

Numerical computation of free surface water flow

Creator:

Kuhnert, Jorg

Abstract:

The present thesis is a report of investigations on a model for computing the water flow in the wave tank of the OSU Wave Laboratory. A wave board, established at one end of the 100 m long, 4 m wide and 6 m deep wave tank, produces water waves by...
