    • Adaptive policies and drawdown problems in insurance risk models 

      Li, Shu (University of Waterloo, 2015-08-31)
      Ruin theory studies an insurer's solvency risk, and to quantify such a risk, a stochastic process is used to model the insurer's surplus process. In fact, research on ruin theory dates back to the pioneer works of Lundberg ...
    • Adaptive Range Counting and Other Frequency-Based Range Query Problems 

      Wilkinson, Bryan T. (University of Waterloo, 2012-05-18)
      We consider variations of range searching in which, given a query range, our goal is to compute some function based on frequencies of points that lie in the range. The most basic such computation involves counting the ...
    • An adaptive variational finite difference framework for efficient symmetric octree viscosity 

      Goldade, Ryan; Wang, Yipeng; Aanjaneya, Mridul; Batty, Christopher (ACM, 2019-07)
      While pressure forces are often the bottleneck in (near-)inviscid fluid simulations, viscosity can impose orders of magnitude greater computational costs at lower Reynolds numbers. We propose an implicit octree finite ...
    • Addressing the Issues of Coalitions and Collusion in Multiagent Systems 

      Kerr, Reid Charles (University of Waterloo, 2013-05-22)
      In the field of multiagent systems, trust and reputation systems are intended to assist agents in finding trustworthy partners with whom to interact. Earlier work of ours identified in theory a number of security ...
    • AddressWatcher: Automatic Memory Leak Fixing 

      Murali, Aniruddhan (University of Waterloo, 2021-12-17)
      Automatic bug fixing has become a promising direction over manual fixing of bugs. In this work, we focus on a specific bug: Memory Leaks. We propose an automatic approach to suggest memory leak fixes in C/C++ programs ...
    • Admission Control for Independently-authored Realtime Applications 

      Kroeger, Robert (University of Waterloo, 2004)
      This thesis presents the LiquiMedia operating system architecture. LiquiMedia is specialized to schedule multimedia applications. Because they generate output for a human observer, multimedia applications such as ...
    • ADMM for SDP Relaxation of GP 

      Sun, Hao (University of Waterloo, 2016-08-30)
      We consider the problem of partitioning the set of nodes of a graph G into k sets of given sizes in order to minimize the cut obtained after removing the k-th set. This is a variant of the well-known vertex separator ...
    • Advanced Concepts in Asynchronous Exception Handling 

      Krischer, Roy (University of Waterloo, 2011-01-21)
      Asynchronous exception handling is a useful and sometimes necessary alternative form of communication among threads. This thesis examines and classifies general concepts related to asynchrony, asynchronous propagation ...
    • Advancements in the Elicitation and Aggregation of Private Information 

      Carvalho, Arthur (University of Waterloo, 2014-08-28)
      There are many situations where one might be interested in eliciting and aggregating the private information of a group of agents. For example, a recommendation system might suggest recommendations based on the aggregate ...
    • Advisor Networks and Referrals for Improved Trust Modelling in Multi-Agent Systems 

      Gorner, Joshua Mark (University of Waterloo, 2011-02-16)
      This thesis relates to the usage of trust modelling in multi-agent systems - environments in which there are interacting software agents representing various users (for example, buyers and sellers exchanging products and ...
    • The aesthetics of science fiction spaceship design 

      Kinnear, Kate (University of Waterloo, 2010-01-18)
      In this thesis, we present a detailed analysis of the conventions that appear in fictional spaceship design, including a discussion of their origins, their uses in emulating certain traits, and reasons these conventions ...
    • Affect Lexicon Induction For the Github Subculture Using Distributed Word Representations 

      Jiao, Yuwei (University of Waterloo, 2018-11-06)
      Sentiments and emotions play essential roles in small group interactions, especially in self-organized collaborative groups. Many people view sentiments as universal constructs; however, cultural differences exist in some ...
    • Affective and Human-Like Virtual Agents 

      Budnarain, Bhavendra (University of Waterloo, 2020-09-29)
      In Artificial Intelligence (AI) one of the technological goals is to build intelligent systems that not only perform human level tasks efficiently, but can also simulate and exhibit human-like behaviour. As the emphasis ...
    • Affective Expressions in Conversational Agents for Learning Environments: Effects of curiosity, humour, and expressive auditory gestures 

      Ceha, Jessy (University of Waterloo, 2021-12-13)
      Conversational agents -- systems that imitate natural language discourse -- are becoming an increasingly prevalent human-computer interface, being employed in various domains including healthcare, customer service, and ...
    • Affective Sentiment and Emotional Analysis of Pull Request Comments on GitHub 

      Rishi, Deepak (University of Waterloo, 2017-12-15)
      Sentiment and emotional analysis on online collaborative software development forums can be very useful to gain important insights into the behaviors and personalities of the developers. Such information can later on be ...
    • An Affine Semi-Lagrangian Advection Method 

      Marcoux-Ouellet, Jade (University of Waterloo, 2019-01-08)
      In computer graphics, the standard semi-Lagrangian advection as in the work of Stam (1999) is a widespread unconditionally stable transport scheme used in incompressible fluid solvers. Due to its stability, which disconnects ...
    • The aftermath of a crypto-ransomware attack at a large academic institution 

      Zhang-Kennedy, Leah; Assal, Hala; Rocheleau, Jessica; Mohamed, Reham; Baig, Khadija; Chiasson, Sonia (USENIX, 2018-08)
      In 2016, a large North American university was subject to a significant crypto-ransomware attack and did not pay the ransom. We conducted a survey with 150 respondents and interviews with 30 affected students, staff, and ...
    • Agent-Based Modeling Framework for Energy Policies 

      Adepetu, Adedamola (University of Waterloo, 2016-08-09)
      Energy infrastructure systems -- including energy generation, transmission, and distribution systems -- provide consumers with access to energy. Energy systems have been relatively static for several decades but due to ...
    • Aggregation of Heterogeneous Anomaly Detectors for Cyber-Physical Systems 

      Dunne, Murray (University of Waterloo, 2019-01-07)
      Distributed, life-critical systems that bridge the gap between software and hardware are becoming an integral part of our everyday lives. From autonomous cars to smart electrical grids, such cyber-physical systems will ...
    • Agile Architecture Recovery 

      Svetinovic, Davor (University of Waterloo, 2002)
      Many software development projects start with an existing code base that has to be tightly integrated into a new system. In order to make a robust system that will achieve the desired business goals, developers must be ...
