      We analyze the effects of dielectric decrement and finite ion size in an aqueous electrolyte on the capacitance of a graphene electrode, and make comparisons with the effects of dielectric saturation combined with finite ...
    • The Effects of Extrinsic and Intrinsic Noise on a Tumour and a Proposed Metastasis Model 

      Tang, Herbert Hoi Chi (University of Waterloo, 2015-11-30)
      Cancer is a ubiquitous disease that afflicts millions of people worldwide and we will undoubtedly encounter it at some point in our lives, whether it be random strangers on the news, or someone much closer. As such, research ...
    • The effects of flagellar hook compliance on motility of monotrichous bacteria: A modeling study 

      Shum, Henry; Gaffney, E. A. (AIP Publishing, 2012-06)
      A crucial structure in the motility of flagellated bacteria is the hook, which connects the flagellum filament to the motor in the cell body. Early mathematical models of swimming bacteria assume that the helically shaped ...
    • Effects of Personality Traits and Emotional Factors in Pull Request Acceptance. 

      Iyer, Rahul (University of Waterloo, 2019-08-26)
      Social interactions in the form of discussion are an indispensable part of collaborative software development. The discussions are essential for developers to share their views and to form a strong relationship with other ...
    • Effects of the Dielectric Environment on the Electrical Properties of Graphene 

      Anicic, Rastko (University of Waterloo, 2013-08-30)
      This thesis provides the study of graphene’s electrostatic interaction with the substrate surrounding it. Mathematical models based on current experimental configurations of graphene field-effect transistors (FET) are ...
    • The Effects of the Earth's Rotation on Internal Wave Near-resonant Triads and Weakly Nonlinear Models 

      Hu, Youna (University of Waterloo, 2007-08-24)
      This thesis investigates the effects of the earth's rotation on internal waves from two perspectives of nonlinear internal wave theory: near-resonant triads and weakly nonlinear models. We apply perturbation theory ...
    • The Effects of Time Constraints and Document Excerpts on Relevance Assessing Behavior 

      Rahbariasl, Shahin (University of Waterloo, 2018-08-30)
      Assessors who judge the relevance of documents to the search topics and perform the relevance assessment process are one of the main parts of Information Retrieval (IR) sys- tems evaluations. They play a significant role ...
    • Efficiency-based hp-refinement for finite element methods 

      Tang, Lei (University of Waterloo, 2007-08-23)
      Two efficiency-based grid refinement strategies are investigated for adaptive finite element solution of partial differential equations. In each refinement step, the elements are ordered in terms of decreasing local ...

    • Efficient and Flexible Search in Large Scale Distributed Systems 

      Ahmed, Reaz (University of Waterloo, 2007-05-18)
      Peer-to-peer (P2P) technology has triggered a wide range of distributed systems beyond simple file-sharing. Distributed XML databases, distributed computing, server-less web publishing and networked resource/service ...
    • Efficient Composition of Discrete Time Quantum Walks 

      Lou, Xingliang (University of Waterloo, 2017-01-20)
      It is well known that certain search problems are efficiently solved by quantum walk algorithms. Of particular interest are those problems whose efficient solutions involve nesting of search algorithms. The nesting of ...
