      Alliheedi, Mohammed (University of Waterloo, 2012-07-11)
      Over the past 20 years, research in automated text summarization has grown significantly in the field of natural language processing. The massive availability of scientific and technical information on the Internet, including ...
    • Multi-Master Replication for Snapshot Isolation Databases 

      Chairunnanda, Prima (University of Waterloo, 2013-06-21)
      Lazy replication with snapshot isolation (SI) has emerged as a popular choice for distributed databases. However, lazy replication requires the execution of update transactions at one (master) site so that it is relatively ...
    • Multi-Path Link Embedding for Survivability in Virtual Networks 

      Alam Khan, Md Mashrur (University of Waterloo, 2015-08-26)
      Internet applications are deployed on the same network infrastructure, yet they have diverse performance and functional requirements. The Internet was not originally designed to support the diversity of current applications. ...
    • Multi-Resolution and Asymmetric Implementation of Attention in Transformers 

      Chaudhry, Zaid (University of Waterloo, 2022-04-29)
      Transformers are the state-of-the-art for machine translation and grammar error correction. One of the most important components of transformers are the attention layers, but they require significant computational power. ...
    • Multi-Resolution Approximate Inverses 

      Bridson, Robert (University of Waterloo, 1999)
      This thesis presents a new preconditioner for elliptic PDE problems on unstructured meshes. Using ideas from second generation wavelets, a multi-resolution basis is constructed to effectively compress the inverse of the ...
    • Multi-scale entropy analysis and Hurst exponent 

      Mollaei, Saeid; Darooneh, Amir Hossein; Karimi, Somaye (Elsevier, 2019-08-15)
      Several methods exist for measuring the complexity in a system through analysis of its associated time series. Multi-scale entropy appears as a successful method on this matter. It has been applied in many disciplines with ...
    • A multi-scale model for coupling strands with shear-dependent liquid 

      Fei, Yun (Raymond); Batty, Christopher; Grinspun, Eitan; Zheng, Changxi (ACM, 2019-11)
      We propose a framework for simulating the complex dynamics of strands interacting with compressible, shear-dependent liquids, such as oil paint, mud, cream, melted chocolate, and pasta sauce. Our framework contains three ...
    • A multi-scale model for simulating liquid-fabric interactions 

      Fei, Yun (Raymond); Batty, Christopher; Grinspun, Eitan; Zheng, Changxi (ACM, 2018-07)
      We propose a method for simulating the complex dynamics of partially and fully saturated woven and knit fabrics interacting with liquid, including the effects of buoyancy, nonlinear drag, pore (capillary) pressure, dripping, ...
    • A Multi-scale Model for Simulating Liquid-hair Interactions 

      Fei, Yun (Raymond); Maia, Henrique Teles; Batty, Christopher; Zheng, Changxi; Grinspun, Eitan (Association for Computing Machinery, 2017-07-20)
      The diverse interactions between hair and liquid are complex and span multiple length scales, yet are central to the appearance of humans and animals in many situations. We therefore propose a novel multi-component simulation ...
    • Multi-scale Models of Tumor Growth and Invasion 

      Soos, Boglarka (University of Waterloo, 2012-10-04)
      Cancer is a complex, multi-scale disease marked by unchecked cellular growth and proliferation. As a tumor grows, it is known to lose its capacity to maintain a compact structure. This stage of development, known as invasion, ...
    • Multi-User File System Search 

      Buettcher, Stefan (University of Waterloo, 2007-08-03)
      Information retrieval research usually deals with globally visible, static document collections. Practical applications, in contrast, like file system search and enterprise search, have to cope with highly dynamic text ...
    • Multigraphs with High Chromatic Index 

      McDonald, Jessica (University of Waterloo, 2009-07-22)
      In this thesis we take a specialized approach to edge-colouring by focusing exclusively on multigraphs with high chromatic index. The bulk of our results can be classified into three categories. First, we prove results ...
    • Multigrid Methods for Hamilton-Jacobi-Bellman and Hamilton-Jacobi-Bellman-Isaacs Equations 

      Han, Dong (University of Waterloo, 2011-06-28)
      We propose multigrid methods for solving Hamilton-Jacobi-Bellman (HJB) and Hamilton-Jacobi-Bellman-Isaacs (HJBI) equations. The methods are based on the full approximation scheme. We propose a damped-relaxation method as ...
    • A Multilevel Method for Image Segmentation 

      Au, Adley (University of Waterloo, 2010-01-18)
      Image segmentation is a branch of computer vision that has received a considerable amount of interest in recent years. Segmentation describes a process that divides or partitions the pixels of a digital image into groups ...
    • Multilingual Grammatical Error Detection And Its Applications to Prompt-Based Correction 

      Sutter Pessurno de Carvalho, Gustavo (University of Waterloo, 2024-01-05)
      Grammatical Error Correction (GEC) and Grammatical Error Correction (GED) are two important tasks in the study of writing assistant technologies. Given an input sentence, the former aims to output a corrected version of ...
    • Multimaterial Mesh-Based Surface Tracking 

      Da, Fang; Batty, Christopher; Grinspun, Eitan (Association for Computing Machinery, 2014-07-01)
