Perceptions and Practicalities for Private Machine Learning
(University of Waterloo, 2023-09-01)data they and their partners hold while maintaining data subjects' privacy. In this thesis I show that private computation, such as private machine learning, can increase end-users' acceptance of data sharing practices, ... -
Perceptual Allowances of Anamorphic Interaction Cues in Spatial Augmented Reality
(University of Waterloo, 2023-10-17)Spatial Augmented Reality (SAR) enables the projection of digital content directly on the physical environment without the use of wearable displays. In spaces where viewers are encouraged to explore different locations, ... -
Perfect Hash Families: Constructions and Applications
(University of Waterloo, 2003)Let <b>A</b> and <b>B</b> be finite sets with |<b>A</b>|=<i>n</i> and |<b>B</b>|=<i>m</i>. An (<i>n</i>,<i>m</i>,<i>w</i>)-<i>perfect hash</i> family</i> is a collection <i>F</i> of functions from <b>A</b> to <b>B</b> ... -
Performance Analysis of Distributed Virtual Environments
(University of Waterloo, 2006)A distributed virtual environment (DVE) is a shared virtual environment where multiple users at their workstations interact with each other. Some of these systems may support a large number of users, e. g. , massive ... -
Performance Comparison of Uniprocessor and Multiprocessor Web Server Architectures
(University of Waterloo, 2010-02-11)This thesis examines web-server architectures for static workloads on both uniprocessor and multiprocessor systems to determine the key factors affecting their performance. The architectures examined are event-driven ... -
A Performance Evaluation of Database Systems on Virtual Machines
(University of Waterloo, 2008-01-16)Virtual machine technologies offer simple and practical mechanisms to address many manageability problems in database systems. For example, these technologies allow for server consolidation, easier deployment, and more ... -
Performance Evaluation of Self-stabilizing Algorithms by Probabilistic Model Checking
(University of Waterloo, 2014-08-08)A self-stabilizing protocol is one that starting from any arbitrary initial state recovers to legitimate states in a finite number of steps, and once it stabilizes to a set of legitimate states, it remains there unless it ... -
Performance Evaluation of WiFi Backscatter Systems
(University of Waterloo, 2020-09-29)WiFi backscatter communication has been proposed to enable battery-free sensors to transmit data using WiFi networks. The main advantage of WiFi backscatter technologies over RFID is that data from their tags can be read ... -
Performance Isolation in Cloud Storage Systems
(University of Waterloo, 2013-09-27)Cloud computing enables data centres to provide resource sharing across multiple tenants. This sharing, however, usually comes at a cost in the form of reduced isolation between tenants, which can lead to inconsistent ... -
Performance of a Cluster that Supports Resource Reservation and On-demand Access
(University of Waterloo, 2009-07-24)Next generation data centres are expected to support both advance resource reservation and on-demand access, but the system performance for such a computing environment has not been well-investigated. A reservation request ... -
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 ... -
