    • Powers and Anti-Powers in Binary Words 

      Riasat, Samin (University of Waterloo, 2019-08-28)
      Fici et al. recently introduced the notion of anti-powers in the context of combinatorics on words. A power (also called tandem repeat) is a sequence of consecutive identical blocks. An anti-power is a sequence of consecutive ...
    • Practical Lattice Cryptosystems: NTRUEncrypt and NTRUMLS 

      Schanck, John (University of Waterloo, 2015-12-22)
      Public key cryptography, as deployed on the internet today, stands on shaky ground. For over twenty years now it has been known that the systems in widespread use are insecure against adversaries equipped with quantum ...
    • A Practical Method for High-Resolution Embedded Liquid Surfaces 

      Goldade, Ryan; Batty, Christopher; Wojtan, Chris (Wiley, 2016-05-01)
      Combining high-resolution level set surface tracking with lower resolution physics is an inexpensive method for achieving highly detailed liquid animations. Unfortunately, the inherent resolution mismatch introduces several ...
    • A practical octree liquid simulator with adaptive surface resolution 

      Ando, Ryoichi; Batty, Christopher (Association for Computing Machinery, 2020-07)
      We propose a new adaptive liquid simulation framework that achieves highly detailed behavior with reduced implementation complexity. Prior work has shown that spatially adaptive grids are efficient for simulating large-scale ...
    • Practical Private Information Retrieval 

      Olumofin, Femi George (University of Waterloo, 2011-08-26)
      In recent years, the subject of online privacy has been attracting much interest, especially as more Internet users than ever are beginning to care about the privacy of their online activities. Privacy concerns are even ...
    • Practical Systems for Personal Thermal Comfort 

      Rabbani Esfahani, Ali Mohammad (University of Waterloo, 2016-04-15)
      Conventional centralized HVAC systems cannot provide office workers with personalized thermal comfort because workers in a single zone share a common air handling unit and thus a single air temperature. Moreover, they heat ...
    • Practices Surrounding Social Use of the Nintendo DS Handheld Gaming System 

      Szentgyorgyi, Christine (University of Waterloo, 2008-05-21)
      Ad-hoc wireless networking has recently become a standard feature of handheld video gaming systems. This capability, along with the portability of the devices, increases the number of places where people can easily engage ...
    • Prandtl number dependence of stratified turbulence 

      Legaspi, Jesse (University of Waterloo, 2019-08-15)
      Stratified turbulence is affected by buoyancy forces that suppress vertical motion, resulting in a horizontally-layered structure with quasi-two-dimensional vortices. The Prandtl number Pr quantifies the relative strengths ...
    • Prandtl number dependence of stratified turbulence 

      Legaspi, Jesse D.; Waite, Michael L (Cambridge, 2020-09-21)
      Stratified turbulence has a horizontally layered structure with quasi-two-dimensional vortices due to buoyancy forces that suppress vertical motion. The Prandtl number Pr quantifies the relative strengths of viscosity ...
    • Preconditioning of Hybridizable Discontinuous Galerkin Discretizations of the Navier-Stokes Equations 

      Sivas, Abdullah Ali (University of Waterloo, 2021-05-19)
      The incompressible Navier-Stokes equations are of major interest due to their importance in modelling fluid flow problems. However, solving the Navier-Stokes equations is a difficult task. To address this problem, in this ...
    • Predicting Endpoint of Goal-Directed Motion in Modern Desktop Interfaces using Motion Kinematics 

      Ruiz, Jaime (University of Waterloo, 2012-04-27)
      Researchers who study pointing facilitation have identified the ability to identify--during motion--the likely target of a user's pointing gesture, as a necessary precursor to pointing facilitation in modern computer ...
    • Predicting epileptic seizures using nonlinear dynamics 

      Marshall, William (University of Waterloo, 2009-01-23)
      Epilepsy is a nervous system disorder which affects approximately 1% of the world's population. Nearly 25% of people who have epilepsy are resistant to traditional treatments such as medication and are not candidates for ...
    • Predicting Repository Upkeep with Textual Personality Analysis 

      Sachs, Alexander (University of Waterloo, 2019-08-29)
      GitHub is an excellent democratic source of software. Unlike traditional work groups however, GitHub repositories are primarily anonymous and virtual. Traditional strategies for improving the productivity of a work group ...
    • Predicting Short-Term Water Consumption for Multi-Family Residences 

      Medina, Irish (University of Waterloo, 2018-09-20)
      Smart water meters have been installed across Abbotsford, British Columbia, Canada, to measure the water consumption of households in the area. Using this water consumption data, we develop machine learning and deep learning ...
    • Predicting Test Suite Effectiveness for Java Programs 

      Inozemtseva, Laura Michelle McLean (University of Waterloo, 2012-07-26)
      The coverage of a test suite is often used as a proxy for its effectiveness. However, previous studies that investigated the influence of code coverage on test suite effectiveness have failed to reach a consensus about ...
    • Prediction and Planning in Dynamical Systems with Underlying Markov Decision Processes 

      Banijamali, Seyedershad (University of Waterloo, 2021-08-24)
      Predicting the future state of a scene with moving objects is a task that humans handle with ease. This is due to our understanding about the dynamics of the objects in the scene and the way they interact. However, teaching ...
    • Prediction of recurrent events 

      Fredette, Marc (University of Waterloo, 2004)
      In this thesis, we will study issues related to prediction problems and put an emphasis on those arising when recurrent events are involved. First we define the basic concepts of frequentist and Bayesian statistical ...
    • Prediction Performance of Survival Models 

      Yuan, Yan (University of Waterloo, 2008-09-12)
      Statistical models are often used for the prediction of future random variables. There are two types of prediction, point prediction and probabilistic prediction. The prediction accuracy is quantified by performance ...
    • Prepositional Phrase Attachment Disambiguation Using WordNet 

      Spitzer, Claus (University of Waterloo, 2006)
      In this thesis we use a knowledge-based approach to disambiguating prepositional phrase attachments in English sentences. This method was first introduced by S. M. Harabagiu. The Penn Treebank corpus is used as ...
    • Preprocessing and Reduction for Semidefinite Programming via Facial Reduction: Theory and Practice 

      Cheung, Yuen-Lam (University of Waterloo, 2013-11-26)
      Semidefinite programming is a powerful modeling tool for a wide range of optimization and feasibility problems. Its prevalent use in practice relies on the fact that a (nearly) optimal solution of a semidefinite program ...
