    • Acyclic Colouring of Graphs on Surfaces 

      Redlin, Shayla (University of Waterloo, 2018-09-04)
      An acyclic k-colouring of a graph G is a proper k-colouring of G with no bichromatic cycles. In 1979, Borodin proved that planar graphs are acyclically 5-colourable, an analog of the Four Colour Theorem. Kawarabayashi and ...
    • Ad-hoc Holistic Ranking Aggregation 

      Saleeb, Mina (University of Waterloo, 2012-12-06)
      Data exploration is considered one of the major processes that enables the user to analyze massive amount of data in order to find the most important and relevant informa- tion needed. Aggregation and Ranking are two of ...
    • Adapting Component Analysis 

      Dorri, Fatemeh (University of Waterloo, 2012-05-18)
      A main problem in machine learning is to predict the response variables of a test set given the training data and its corresponding response variables. A predictive model can perform satisfactorily only if the training ...
    • Adaptive Algorithms for Weighted Queries on Weighted Binary Relations and Labeled Trees 

      Veraskouski, Aleh (University of Waterloo, 2007-07-30)
      Keyword queries are extremely easy for a user to write. They have become a standard way to query for information in web search engines and most other information retrieval systems whose users are usually laypersons and ...
    • Adaptive Comparison-Based Algorithms for Evaluating Set Queries 

      Mirzazadeh, Mehdi (University of Waterloo, 2004)
      In this thesis we study a problem that arises in answering boolean queries submitted to a search engine. Usually a search engine stores the set of IDs of documents containing each word in a pre-computed sorted order and ...
    • An Adaptive Context-Aware Publish–Subscribe Component Metamodel 

      Blanco, Luis (University of Waterloo, 2015-01-16)
      There are plenty of solutions in which the functionality for context awareness is separated from the domain-specific functionality. Also, there are multiple ways of modeling, gathering, and processing context-related ...
    • Adaptive CPU Allocation for Resource Isolation and Work Conservation 

      Guo, Cong (University of Waterloo, 2020-07-06)
      Consolidating multiple workloads on the same physical machine is an effective measure for utilizing resources efficiently and reducing costs. The main objective is to execute multiple demanding workloads using no more than ...
    • Adaptive Fusion Techniques for Effective Multimodal Deep Learning 

      Sahu, Gaurav (University of Waterloo, 2020-08-28)
      Effective fusion of data from multiple modalities, such as video, speech, and text, is a challenging task due to the heterogeneous nature of multimodal data. In this work, we propose fusion techniques that aim to model ...
    • 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 ...
    • 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 ...
