    • Business Policy Modeling and Enforcement in Relational Database Systems 

      Ataullah, Ahmed Ayaz (University of Waterloo, 2014-05-12)
      Database systems maintain integrity of the stored information by ensuring that modifications to the database comply with constraints designed by the administrators. As the number of users and applications sharing a common ...
    • Cache Design for a Hardware Accelerated Sparse Texture Storage System 

      Yee, Wai Min (University of Waterloo, 2004)
      Hardware texture mapping is essential for real-time rendering. Unfortunately the memory bandwidth and latency often bounds performance in current graphics architectures. Bandwidth consumption can be reduced by ...
    • Cache Oblivious Data Structures 

      Ohashi, Darin (University of Waterloo, 2001)
      This thesis discusses cache oblivious data structures. These are structures which have good caching characteristics without knowing Z, the size of the cache, or L, the length of a cache line. Since the structures do ...
    • Cache-Aware Virtual Page Management 

      Szlavik, Alexander (University of Waterloo, 2013-02-22)
      With contemporary research focusing its attention primarily on benchmark-driven performance evaluation, studying fundamental memory characteristics has gone by the way-side. This thesis presents a systematic study of the ...
    • Cache-Oblivious Searching and Sorting in Multisets 

      Farzan, Arash (University of Waterloo, 2004)
      We study three problems related to searching and sorting in multisets in the cache-oblivious model: Finding the most frequent element (the mode), duplicate elimination and finally multi-sorting. We are interested in ...
    • The Capacitated Matroid Median Problem 

      Kalhan, Sanchit (University of Waterloo, 2018-05-18)
      In this thesis, we study the capacitated generalization of the Matroid Median Problem which is a generalization of the classical clustering problem called the k-Median problem. In the capacitated matroid median problem, ...
    • Capacitated Network Design on Outerplanar Graphs 

      Bansal, Ishan (University of Waterloo, 2020-09-03)
      Network design problems model the efficient allocation of resources like routers, optical fibres, roads, canals etc. to effectively construct and operate critical infrastructures. In this thesis, we consider the capacitated ...
    • Carrot Or Stick? Modelling How Landowner Behavioural Responses Can Cause Incentive-Based Forest Governance To Backfire 

      Henderson, Kirsten A.; Anand, Madhur; Bauch, Chris T. (Public Library of Science, 2013-10-30)
      Mitigating the negative impacts of declining worldwide forest cover remains a significant socio-ecological challenge, due to the dominant role of human decision-making. Here we use a Markov chain model of land-use dynamics ...
    • Case Studies of a Machine Learning Process for Improving the Accuracy of Static Analysis Tools 

      Zhao, Peng (University of Waterloo, 2016-10-18)
      Static analysis tools analyze source code and report suspected problems as warnings to the user. The use of these tools is a key feature of most modern software development processes; however, the tools tend to generate ...
    • A Case Study of a Very Large Organization 

      Werner, Colin Mark (University of Waterloo, 2012-01-04)
      Very Large Organization (VLO) is an organization that produces hardware and software, which together form products. VLO granted access to data pertaining to seven different products and their development projects. One ...
    • Case Study of Feature-Oriented Requirements Modelling, Applied to an Online Trading System 

      Krulec, Ana (University of Waterloo, 2011-01-12)
      The Feature-Oriented Requirements Modelling (FORM) combines the requirement engineering style structuring of requirements documents with the feature-orientation of the Feature Oriented Software Development, resulting in a ...
    • Causal Inference with Covariate Balance Optimization 

      Xie, Yuying (University of Waterloo, 2018-12-04)
      Causal inference is a popular problem in biostatistics, economics, and health science studies. The goal of this thesis is to develop new methods for the estimation of causal effects using propensity scores or inverse ...
    • Causal Inference with Measurement Error 

      Shu, Di (University of Waterloo, 2018-05-04)
      Causal inference methods have been widely used in biomedical sciences and social sciences, among many others. With different assumptions, various methods have been proposed to conduct causal inference with interpretable ...
    • Causal Inference with Recurrent Data via Propensity Score Methods 

      Liang, Haodi (University of Waterloo, 2019-01-07)
      Propensity score methods are increasingly being used to reduce estimation bias of treatment effects for observational studies. Previous research has shown that propensity score methods consistently estimate the marginal ...
    • Causal Sensitivity Analysis for Decision Trees 

      Li, Chengbo (University of Waterloo, 2015-01-15)
      Ventilator assignments in the pediatric intensive care unit (PICU) are made by medical experts; however, for some patients the relationship between ventilator assignment and patient health status is not well understood. ...
    • CBKR+: A Conceptual Framework for Improving Corpus Based Knowledge Representation 

      Ivkovic, Shabnam (University of Waterloo, 2006)
      In Corpus Based Knowledge Representation [CBKR], limited association capability, that is, no criteria in place to extract substantial associations in the corpus, and lack of support for hypothesis testing and prediction ...
