Fully Automated Translation of BoxTalk to Promela
(University of Waterloo, 2011-08-26)Telecommunication systems are structured to enable incremental growth, so that new telecommunication features can be added to the set of existing features. With the addition of more features, certain existing features may ... -
Function-valued Mappings and SSIM-based Optimization in Imaging
(University of Waterloo, 2015-08-27)In a few words, this thesis is concerned with two alternative approaches to imag- ing, namely, Function-valued Mappings (FVMs) and Structural Similarity Index Measure (SSIM)-based Optimization. Briefly, a FVM is a mathematical ... -
Functional Finite Mixture Modelling and Estimation
(University of Waterloo, 2023-09-01)Functional data analysis is a branch of statistics that studies models for information represented by functions. Meanwhile, finite mixture models serve as a conerstone in the field of cluster analysis, offering a flexible ... -
Fundamental Limitations of Semi-Supervised Learning
(University of Waterloo, 2009-05-05)The emergence of a new paradigm in machine learning known as semi-supervised learning (SSL) has seen benefits to many applications where labeled data is expensive to obtain. However, unlike supervised learning (SL), which ... -
A Fundamentally Topological Perspective on Graph Theory
(University of Waterloo, 2005)We adopt a novel topological approach for graphs, in which edges are modelled as points as opposed to arcs. The model of classical <i>topologized graphs</i> translates graph isomorphism into topological homeomorphism, ... -
Funding Liquidity and Limits to Arbitrage
(University of Waterloo, 2012-06-14)Arbitrageurs play an important role in keeping market prices close to their fundamental values by providing market liquidity. Most arbitrageurs however use leverage. When funding conditions worsen they are forced to ... -
Future Sight: Dynamic Story Generation with Large Pretrained Language Models
(University of Waterloo, 2022-08-23)Automated story generation has been an open problem in computing for many decades. Only with the recent wave of deep learning research have neural networks been applied to automated story generation tasks. Current deep ... -
A Fuzzy-logic based Alert Prioritization Engine for IDSs: Architecture and Configuration
(University of Waterloo, 2008-01-16)Intrusion Detection Systems (IDSs) are designed to monitor a networked environment and generate alerts whenever abnormal activities are detected. The number of these alerts can be very large making their evaluation by ... -
FX Spot Trading and Risk Management from A Market Maker’s Perspective
(University of Waterloo, 2011-08-29)Due to the rapid development of computing technology and faster growth of financial industry, Foreign Exchange high-frequency trading has become substantially more prominent to today's market players, especially to bankers ... -
Gain-Scheduled Control of a Quadcopter UAV
(University of Waterloo, 2015-07-28)In this thesis we develop a gain-scheduled control law for the quadcopter unmanned aerial vehicle (UAV). Techniques from linear control theory are introduced and used to construct adaptive proportional and proportional-integral ... -
Gaining Information About a Quantum Channel Via Twirling
(University of Waterloo, 2008-07-31)Finding correctable encoding that protects against a quantum process is in general a difficult task. Two main obstacles are that an exponential number of experiments are needed to gain complete information about the quantum ... -
Galerkin Finite Element Based Modeling of One Dimensional Packed Bed Reactor for Underground Coal Gasification (UCG) Process
(IEEE, 2020-12-11)Mathematical models of a complex physicochemical underground coal gasification process involve multidimensional non-linear partial differential equations (PDEs). Therefore, researchers always seek a suitable numerical ... -
General Geometry Computed Tomography Reconstruction
(University of Waterloo, 2006)The discovery of Carbon Nanotubes and their ability to produce X-rays can usher in a new era in Computed Tomography (CT) technology. These devices will be lightweight, flexible and portable. The proposed device, currently ... -
A General Neural Network Methodology for Multi-period Portfolio Optimization
(University of Waterloo, 2024-01-22)In this thesis, we propose a neural network methodology for solving the multi-period portfolio optimization problem. Our approach formulates the problem as a stochastic optimal control problem and uses a single neural ... -
General Quadratic Risk Minimization: a Variational Approach
(University of Waterloo, 2016-07-05)Mean-variance portfolio selection and mean-variance hedging are mainstream research topics in mathematical nance, which can be subsumed within the framework of a general problem of quadratic risk minimization. We study ... -
Generalisations of Roth's theorem on finite abelian groups
(University of Waterloo, 2012-12-18)Roth's theorem, proved by Roth in 1953, states that when A is a subset of the integers [1,N] with A dense enough, A has a three term arithmetic progression (3-AP). Since then the bound originally given by Roth has been ... -
A Generalization of M/G/1 Priority Models via Accumulating Priority
(University of Waterloo, 2016-01-08)Priority queueing systems are oftentimes set up so that arriving customers are placed into one of $N$ distinct priority classes. Moreover, to determine the order of service, each customer (upon arriving to the system) is ... -
A Generalization of the Discounted Penalty Function in Ruin Theory
(University of Waterloo, 2008-08-21)As ruin theory evolves in recent years, there has been a variety of quantities pertaining to an insurer's bankruptcy at the centre of focus in the literature. Despite the fact that these quantities are distinct from each ... -
Generalization on Text-based Games using Structured Belief Representations
(University of Waterloo, 2020-12-23)Text-based games are complex, interactive simulations where a player is asked to process the text describing the underlying state of the world to issue textual commands for advancing in a game. Playing these games can be ... -
A Generalization to Signed Graphs of a Theorem of Sergey Norin and Robin Thomas
(University of Waterloo, 2019-12-19)In this thesis we characterize the minimal non-planar extensions of a signed graph. We consider the following question: Given a subdivision of a planar signed graph (G, Σ), what are the minimal structures that can be added ...
