    • A Cox-Aalen model for interval-censored data 

      Cook, Richard J.; Boruvka, Audrey (Wiley, 2015-06)
      The Cox-Aalen model, obtained by replacing the baseline hazard function in the well-known Cox model with a covariate-dependent Aalen model, allows for both fixed and dynamic covariate effects. In this paper, we examine ...
    • Cracking the Code: Unraveling Gender Disparities in Open-Source Contributions 

      Abbas, Norhan Abbas Fathy (University of Waterloo, 2023-09-28)
      Within the world of open source software (OSS) development, previous research has shown that the success rate of pull requests (PRs) may exhibit gender-related imbalances. In this work, we seek to examine which factors ...

      Gobaan, Raveendran (University of Waterloo, 2013-11-29)
      Traditionally, public opinion and policy is decided by issuing surveys and performing censuses designed to measure what the public thinks about a certain topic. Within the past five years social networks such as Facebook ...
    • Creating an Emotion Responsive Dialogue System 

      Vadehra, Ankit (University of Waterloo, 2018-10-19)
      The popularity of deep neural networks and vast amounts of readily available multi-domain textual data has seen the advent of various domain/task specific and domain agnostic dialogue systems. In our work, we present a ...
    • Creating Your Bubble: Personal Space On and Around Large Public Displays 

      Wallace, James R.; Iskander, Nancy; Lank, Edward (ACM, 2016-05)
      We describe an empirical study that explores how users establish and use personal space around large public displays (LPDs). Our study complements field studies in this space by more fully characterizing interpersonal ...
    • Critical Dynamics In Population Vaccinating Behavior 

      Pananos, A. Demetri; Bury, Thomas M.; Wang, Clara; Schonfeld, Justin; Mohanty, Sharada P.; Nyhan, Brendan; Salathe, Marcel; Bauch, Chris T. (National Academy of Sciences, 2017-12-26)
      Vaccine refusal can lead to renewed outbreaks of previously eliminated diseases and even delay global eradication. Vaccinating decisions exemplify a complex, coupled system where vaccinating behavior and disease dynamics ...
    • A Critical Examination of Two Specific Approaches Used to Characterize Medical Images: i) Projection-based Descriptors for Image Retrieval and ii) Estimating Fractal Dimensions of Discrete Sets 

      Cheeseman, Alison (University of Waterloo, 2022-08-31)
      In this thesis we provide a critical examination of two methods which are used to characterize medical images. Accordingly, this thesis is split into two main parts. First, we take a look at the problem of designing ...
    • Critical Exponents and Stabilizers of Infinite Words 

      Krieger, Dalia (University of Waterloo, 2008-04-01)
      This thesis concerns infinite words over finite alphabets. It contributes to two topics in this area: critical exponents and stabilizers. Let w be a right-infinite word defined over a finite alphabet. The critical ...
    • Critical exponents of infinite balanced words 

      Rampersad, Narad; Shallit, Jeffrey; Vandomme, Élise (Elsevier, 2019-07-19)
      Over an alphabet of size 3 we construct an infinite balanced word with critical exponent 2 + root2/2. Over an alphabet of size 4 we construct an infinite balanced word with critical exponent (5 + root5)/4. Over larger ...
    • A critical review of 'optimal' annuitization strategies 

      Mendu, Harish (University of Waterloo, 2021-01-28)
      This paper is an analysis of different self-annuitization strategies advised to a retiree. At the time of retirement, an individual has the choice between annuitizing immediately with their wealth or delaying until a future ...
    • Cross-Domain Sentence Modeling for Relevance Transfer with BERT 

      Akkalyoncu Yilmaz, Zeynep (University of Waterloo, 2019-12-16)
      Standard bag-of-words term-matching techniques in document retrieval fail to exploit rich semantic information embedded in the document texts. One promising recent trend in facilitating context-aware semantic matching has ...
    • Cross-Lingual Entity Matching for Knowledge Graphs 

      Yang, Hsiu-Wei (University of Waterloo, 2020-12-14)
      Multilingual knowledge graphs (KGs), such as YAGO and DBpedia, represent entities in different languages. The task of cross-lingual entity matching is to align entities in a source language with their counterparts in target ...
    • Cross-monotonic Cost-Sharing Methods for Network Design Games 

      Wheatley, David (University of Waterloo, 2007-09-26)
      In this thesis we consider some network design games that arise from common network design problems. A network design game involves multiple players who control nodes in a network, each of which has a personal interest ...
    • Cryptographic End-to-end Verification for Real-world Elections 

      Essex, Aleksander (University of Waterloo, 2012-07-05)
      In this dissertation we study the problem of making electronic voting trustworthy through the use of cryptographic end-to-end (E2E) audits. In particular, we present a series of novel proposals for cryptographic election ...
    • Cryptographic Protocols, Sensor Network Key Management, and RFID Authentication 

      Wu, Jiang (University of Waterloo, 2009-06-26)
      This thesis includes my research on efficient cryptographic protocols, sensor network key management, and radio frequency identification (RFID) authentication protocols. Key exchange, identification, and public key ...
    • Cryptography and Privacy in Vehicular Communication Networks 

      Sharma, Pravek (University of Waterloo, 2023-08-28)
      Wireless communication technologies can support dynamic networks between vehicles, pedestrians and roadside infrastructure called Vehicular Ad hoc Networks (VANETs). Wireless communication over VANETs allows for several ...
    • Crystallizing Application Configurations 

      Zhang, Zanqing (University of Waterloo, 2006)
      Software applications have both static and dynamic dependencies. Static dependencies are those derived from the source code. Dynamic runtime dependencies are established at runtime and may be based on information ...
    • Customizing kernels in Support Vector Machines 

      Zhang, Zhanyang (University of Waterloo, 2007-05-22)
      Support Vector Machines have been used to do classification and regression analysis. One important part of SVMs are the kernels. Although there are several widely used kernel functions, a carefully designed kernel will ...
