#### Vacuum Energy in Expanding Spacetime and Superoscillation - Induced Resonance

(University of Waterloo, 2008-05-20)

This thesis is divided into two parts. The first part is a study of
the general problem of vacuum energy or so-called `zero point
fluctuations' of a quantum field on expanding spacetimes and the
interplay between the ...

#### The Effects of the Earth's Rotation on Internal Wave Near-resonant Triads and Weakly Nonlinear Models

(University of Waterloo, 2007-08-24)

This thesis investigates the effects of the earth's rotation on internal waves from two perspectives of nonlinear internal wave theory: near-resonant triads and weakly nonlinear models.
We apply perturbation theory ...

#### Hedging Contingent Claims in Markets with Jumps

(University of Waterloo, 2007-09-25)

Contrary to the
Black-Scholes paradigm,
an option-pricing model which incorporates the possibility of
jumps
more
accurately reflects the
evolution of stocks in the real world.
However, hedging a contingent claim
in ...

#### Distorted Wave Born Approximation For Inelastic Atomic Collision

(University of Waterloo, 2007-07-17)

An investigation of the problem of inelastic scattering process under the Coulomb
Born approximation is given. Different approaches to calculate Coulomb wavefunctions
in the momentum space representation are analyzed and ...

#### Spectral analysis of internal waves generated by tide-topography interaction

(University of Waterloo, 2007-08-21)

Internal waves in the deep ocean play a deciding role in processes such as climate change and nutrient cycles. Winds and tidal currents over topography feed energy into internal waves at large scales; through nonlinear ...

#### Efficiency-based hp-refinement for finite element methods

(University of Waterloo, 2007-08-23)

Two efficiency-based grid refinement strategies are investigated for adaptive finite element
solution of partial differential equations. In each refinement step, the elements are ordered
in terms of decreasing local ...

#### Entire Solutions to Dirichlet Type Problems

(University of Waterloo, 2007-08-02)

In this thesis, we examined some Dirichlet type problems of
the form:
\begin{eqnarray*}
\triangle u & = & 0\ {\rm in\ } \mathbb{R}^n \\
u & = & f\ {\rm on\ } \psi = 0,
\end{eqnarray*}
and we were particularly ...

#### Analysis of Asymptotic Solutions for Cusp Problems in Capillarity

(University of Waterloo, 2007-09-27)

The capillary surface $u(x,y)$ near a cusp region satisfies the boundary value problem:
\begin{eqnarray}
\nabla \cdot \frac{\nabla u}{\sqrt{1+\left|\nabla u \right|^2}}&=&\kappa u \qquad \textrm{in }\left\{(x,y): ...

#### Optimal Dither and Noise Shaping in Image Processing

(University of Waterloo, 2008-08-20)

Dithered quantization and noise shaping is well known in the audio community. The image processing community seems to be aware of this same theory only in bits and pieces, and frequently under conflicting terminology. ...

#### A Hybrid Cellular Automata Model for the Role of Reactive Oxygen Species in Novel Tumour Treatments Strategies

(University of Waterloo, 2015-01-21)

Cancer is a disease that entails uncontrolled proliferation and a disruption of tissue function that often results in a poor clinical outcome. Furthermore, it has continued to elude any universal treatment or cure in part ...
