#### 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 ...

#### Computation of Multivariate Barrier Crossing Probability, and Its Applications in Finance

(University of Waterloo, 2007-09-05)

In this thesis, we consider computational methods of finding exit probabilities for a class of multivariate stochastic
processes. While there is an abundance of results for one-dimensional processes, for multivariate ...

#### Artin's Primitive Root Conjecture and its Extension to Compositie Moduli

(University of Waterloo, 2008-08-11)

If we fix an integer a not equal to -1 and which is not a perfect square, we are interested in estimating the quantity N_{a}(x) representing the number of prime integers p up to x such that a is a generator of the cyclic ...

#### Anonymous, Secure and Efficient Vehicular Communications

(University of Waterloo, 2007-09-20)

Vehicular communication networking is a promising approach for facilitating road safety, traffic management, and infotainment dissemination for drivers and passengers. However, it is subject to various malicious abuses and ...

#### Key establishment --- security models, protocols and usage

(University of Waterloo, 2008-07-30)

Key establishment is the process whereby two or more parties derive a shared
secret, typically used for subsequent confidential communication. However,
identifying the exact security requirements for key establishment ...

#### Interval Censoring and Longitudinal Survey Data

(University of Waterloo, 2007-09-11)

Being able to explore a relationship between two life events is of great interest to scientists from different disciplines. Some issues of particular concern are, for example, the connection between smoking cessation and ...

#### On a Question of Wintner Concerning the Sequence of Integers Composed of Primes from a Given Set

(University of Waterloo, 2007-09-27)

We answer to a Wintner's question
concerning the sequence of integers
composed of primes from a given set.
The results generalize and develop the answer to Wintner’s question due to
Tijdeman.

#### 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 ...

#### FLECS: A Data-Driven Framework for Rapid Protocol Prototyping

(University of Waterloo, 2007-09-11)

Flecs is a framework for facilitating rapid implementation of communication protocols.
Forwarding functionality of protocols can be modeled as a combination of packet processing components called abstract switching elements ...

#### Aspects of Metric Spaces in Computation

(University of Waterloo, 2008-06-06)

Metric spaces, which generalise the properties of commonly-encountered physical and abstract spaces into a mathematical framework, frequently occur in computer science applications. Three major kinds of questions about ...
