    • A 2-Approximation for the Height of Maximal Outerplanar Graph Drawings 

      Demontigny, Philippe (University of Waterloo, 2016-08-18)
      In this thesis, we study drawings of maximal outerplanar graphs that place vertices on integer coordinates. We introduce a new class of graphs, called umbrellas, and a new method of splitting maximal outerplanar graphs ...
    • 3-D Reconstruction from Single Projections, with Applications to Astronomical Images 

      Cormier, Michael (University of Waterloo, 2013-08-23)
      A variety of techniques exist for three-dimensional reconstruction when multiple views are available, but less attention has been given to reconstruction when only a single view is available. Such a situation is normal in ...
    • 3D Pointing with Everyday Devices: Speed, Occlusion, Fatigue 

      Pietroszek, Krzysztof (University of Waterloo, 2015-07-24)
      In recent years, display technology has evolved to the point where displays can be both non-stereoscopic and stereoscopic, and 3D environments can be rendered realistically on many types of displays. From movie theatres ...
    • Access Control Administration with Adjustable Decentralization 

      Chinaei, Amir Hossein (University of Waterloo, 2007-09-12)
      Access control is a key function of enterprises that preserve and propagate massive data. Access control enforcement and administration are two major components of the system. On one hand, enterprises are responsible for ...
    • Achieving Performance Objectives for Database Workloads 

      Mallampalli, Anusha (University of Waterloo, 2010-08-30)
      In this thesis, our goal is to achieve customer-specified performance objectives for workloads in a database management system (DBMS). Competing workloads in current DBMSs have detrimental effects on performance. ...
    • Active Learning with Semi-Supervised Support Vector Machines 

      Chinaei, Leila (University of Waterloo, 2007-05-22)
      A significant problem in many machine learning tasks is that it is time consuming and costly to gather the necessary labeled data for training the learning algorithm to a reasonable level of performance. In reality, it is ...
    • Active Sensing for Partially Observable Markov Decision Processes 

      Koltunova, Veronika (University of Waterloo, 2013-01-21)
      Context information on a smart phone can be used to tailor applications for specific situations (e.g. provide tailored routing advice based on location, gas prices and traffic). However, typical context-aware smart phone ...
    • 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 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 ...
    • Addressing the Issues of Coalitions and Collusion in Multiagent Systems 

      Kerr, Reid C. (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 ...
    • 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 ...
    • 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 ...
