      Fortes Tondello, Gustavo; Orji, Rita; Vella, Kellie; Johnson, Daniel; Van Dooren, Marierose; Nacke, Lennart (Association for Computing Machinery, 2017-10-15)
      Gamification and games have been used and studied in a variety of applications related with health and wellbeing. Nevertheless, there are very few studies aimed at designing games (whether serious games or recreational ...
    • A Positive-definite Cut-cell Method for Strong Two-way Coupling Between Fluids and Deformable Bodies 

      Zarifi, Omar; Batty, Christopher (Association for Computing Machinery, 2017-07-28)
      We present a new approach to simulation of two-way coupling between inviscid free surface fluids and deformable bodies that exhibits several notable advantages over previous techniques. By fully incorporating the dynamics ...
    • Post-Quantum Elliptic Curve Cryptography 

      Soukharev, Vladimir (University of Waterloo, 2016-05-16)
      We propose and develop new schemes for post-quantum cryptography based on isogenies over elliptic curves. First we show that ordinary elliptic curves are have less than exponential security against quantum computers. These ...
    • Power Diagrams and Sparse Paged Grids for High Resolution Adaptive Liquids 

      Aanjaneya, Mridul; Gao, Ming; Liu, Haixiang; Batty, Christopher; Sifakis, Eftychios (Association for Computing Machinery, 2017-07-20)
      We present an efficient and scalable octree-inspired fluid simulation framework with the flexibility to leverage adaptivity in any part of the computational domain, even when resolution transitions reach the free surface. ...
    • The Power Landmark Vector Learning Framework 

      Xiang, Shuo (University of Waterloo, 2008-05-12)
      Kernel methods have recently become popular in bioinformatics machine learning. Kernel methods allow linear algorithms to be applied to non-linear learning situations. By using kernels, non-linear learning problems can ...
    • A Power-Efficient Smart Lighting System: Modeling, Implementation and Evaluation 

      Aussat, Yerbol (University of Waterloo, 2019-09-03)
      Lighting load accounts for approximately one third of overall energy consumption in modern office buildings. To reduce this load, we have designed a smart lighting control system that attempts to minimize power consumption, ...
    • 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 ...
    • 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 ...
