    Stochastic satisfiability (SSAT), Quantified Boolean Satisfiability (QBF) and decision-theoretic planning in finite horizon partially observable Markov decision processes (POMDPs) are all PSPACE-Complete problems. Since ...
  • Improving the Performance of User-level Runtime Systems for Concurrent Applications 

    Barghi, Saman (University of Waterloo, 2018-09-25)
    Concurrency is an essential part of many modern large-scale software systems. Applications must handle millions of simultaneous requests from millions of connected devices. Handling such a large number of concurrent ...
  • Resource Orchestration in Softwarized Networks 

    Bari, Md. Faizul (University of Waterloo, 2018-09-24)
    Network softwarization is an emerging research area that is envisioned to revolutionize the way network infrastructure is designed, operated, and managed today. Contemporary telecommunication networks are going through a ...
  • Fast Algorithms for Finding the Characteristic Polynomial of a Rank-2 Drinfeld Module 

    Musleh, Yossef (University of Waterloo, 2018-09-21)
    This thesis introduces a new Monte Carlo randomized algorithm for computing the characteristic polynomial of a rank-2 Drinfeld module. We also introduce a deterministic algorithm that uses some ideas seen in Schoof's ...
  • Dynamic Security Orchestration System Leveraging Machine Learning 

    Jalalpour, Elaheh (University of Waterloo, 2018-09-20)
    A Content Delivery Network (CDN) employs edge-servers caching content close to end-users to provide high Quality of Service (QoS) in serving digital content. Attacks against edge-servers are known to cause QoS degradation ...
  • Discovering Play Store Reviews Related to Specific Android App Issues 

    Ghosh, Angshuman (University of Waterloo, 2018-09-20)
    Mobile App reviews may contain information relevant to developers. Developers can investigate these reviews to see what users of their apps are complaining about. However, the huge volume of incoming reviews is impractical ...
  • 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 ...
  • Privately Constrained Testable Pseudorandom Functions 

    Pawlega, Filip (University of Waterloo, 2018-09-20)
    Privately Constrained Pseudorandom Functions allow a PRF key to be delegated to some evaluator in a constrained manner, such that the key’s functionality is restricted with respect to some secret predicate. Variants of ...
  • Personalizing Persuasive Strategies in Gameful Systems to Gamification User Types 

    Orji, Rita; Fortes Tondello, Gustavo; Nacke, Lennart (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 ...
  • Towards a Trait Model of Video Game Preferences 

    Fortes Tondello, Gustavo; Valtchanov, Deltcho; Reetz, Adrian; Wehbe, Rina Renee; Orji, Rita; Nacke, Lennart (Taylor & Francis, 2018-04-19)
    Typologies for understanding players’ preferences toward different gameplay styles have gained popularity in research. However, attempts to model players’ preferences are based on type models instead of trait models, ...
  • Positive Gaming: Workshop on Gamification and Games for Wellbeing 

    Fortes Tondello, Gustavo; Orji, Rita; Vella, Kellie; Johnson, Daniel; Van Dooren, Marierose; Nacke, Lennart (Association for Computing Machinery, 2017-10-15)
