Performance of Dynamic Hedging Strategies for Cash Balance Pension Plans
(University of Waterloo, 2015-09-28)Cash balance (CB) pension plans make up 25% of all defined benefit plans in the US. The benefits are accumulated at guaranteed crediting rates, the most popular choice is the yield on the 30-year Treasury bond. In this ... -
Performance of the Ultra-Wide Word Model
(University of Waterloo, 2017-09-08)The Ultra-wide word model of computation (UWRAM) is an extension of the Word-RAM model which has an ALU that can operate on w^2 bits at a time, where w is the size in bits of a cell in memory. The purpose of this thesis ... -
Periodicity and Repetition in Combinatorics on Words
(University of Waterloo, 2004)This thesis concerns combinatorics on words. I present many results in this area, united by the common themes of periodicity and repetition. Most of these results have already appeared in journal or conference ... -
Persistent oscillations in the Aplysia bag cell network
(University of Waterloo, 2017-08-24)Persistence is a phenomena by which a resting neuron enters a state of persistent behavior following a brief stimulus. Persistent neural systems can exhibit long-term responses that remain after the stimulus is removed, ... -
Persona-based target-guided dialogue systems: A use case in dementia care
(University of Waterloo, 2024-01-19)In recent years, conversational agents have shown potential in various applications. However, the development of conversational agents tailored for older adults, particularly those with age-related cognitive limitations, ... -
Personal Data Management in the Internet of Things
(University of Waterloo, 2015-12-08)Due to a sharp decrease in hardware costs and shrinking form factors, networked sensors have become ubiquitous. Today, a variety of sensors are embedded into smartphones, tablets, and personal wearable devices, and are ... -
Personal Email Spam Filtering with Minimal User Interaction
(University of Waterloo, 2012-04-30)This thesis investigates ways to reduce or eliminate the necessity of user input to learning-based personal email spam filters. Personal spam filters have been shown in previous studies to yield superior effectiveness, ... -
Personality Traits of GitHub Maintainers and Their Effects on Project Success
(University of Waterloo, 2020-08-28)Online collaborative environments have become important virtual workplaces for developers to work on a common problem. GitHub is an example of such environment that hosts a wealth of open source software projects. Questions ... -
Personalizing Persuasive Strategies in Gameful Systems to Gamification User Types
(Association for Computing Machinery, 2018-04-21)Persuasive gameful systems are effective tools for motivating behaviour change. Research has shown that tailoring these systems to individuals can increase their efficacy; however, there is little knowledge on how to ... -
Perspective in Two Dimensions for Computer Graphics
(University of Waterloo, 2013-01-28)Computer graphics perspective is based on photography, the pin-hole camera model. This thesis examines the perspective as practiced by artists, who develop the picture geometry within the planar surface of the canvas. Their ... -
Perspectives on software-defined networks: interviews with five leading scientists from the networking community
(SpringerOpen, 2015-10-30)Software defined Networks (SDNs) have drawn much attention both from academia and industry over the last few years. Despite the fact that underlying ideas already exist through areas such as P2P applications and active ... -
A Phase Model with Large Time Delayed Coupling
(Elsevier, 2020-10)We consider two identical oscillators with weak, time delayed coupling. We start with a general system of delay differential equations then reduce it to a phase model. With the assumption of large time delay, the resulting ... -
Phase models and clustering in networks of oscillators with delayed coupling
(Elsevier, 2017-09-19)We consider a general model for a network of oscillators with time delayed coupling where the coupling matrix is circulant. We use the theory of weakly coupled oscillators to reduce the system of delay differential equations ... -
Physical Design for Non-relational Data Systems
(University of Waterloo, 2018-08-09)Decades of research have gone into the optimization of physical designs, query execution, and related tools for relational databases. These techniques and tools make it possible for non-expert users to make effective use ... -
Physical Modelling and the Associated Acoustic Behaviour of Trumpets and Trombones
(University of Waterloo, 2019-09-30)Accurately modelling the production of realistic musical notes in brass instruments is no easy task. Compared to woodwind instruments, brass instruments are considerably longer and constructed with bends, valves or coils, ... -
Physically-based Simulation of Tornadoes
(University of Waterloo, 2005)In this physically-based tornado simulation, the tornado-scale approach techniques are applied to simulate the tornado formation environment. The three-dimensional Navier-Stokes equations for incompressible viscous ... -
Pick Interpolation and the Distance Formula
(University of Waterloo, 2012-05-09)The classical interpolation theorem for the open complex unit disk, due to Nevanlinna and Pick in the early 20th century, gives an elegant criterion for the solvability of the problem as an eigenvalue problem. In the 1960s, ... -
PID Control of Systems with Hysteresis
(University of Waterloo, 2009-04-29)Hysteresis is exhibited by many physical systems. Smart materials such as piezoelectrics, magnetostrictives and shape memory alloys possess useful properties, especially in the field of micropositioning, but the control ... -
Piercing axis-parallel boxes
(The Electronic Journal of Combinatorics, 2018)Let F be a finite family of axis-parallel boxes in Rd such that F contains no k + 1 pairwise disjoint boxes. We prove that if F contains a subfamily M of k pairwise disjoint boxes with the property that for every F E F ... -
Pixelating Vector Art
(University of Waterloo, 2014-01-09)Pixel art is a popular style of digital art often found in video games. It is typically characterized by its low resolution and use of limited colour palettes. Pixel art is created manually with little automation because ...
