Welcome to the Faculty of Mathematics community.

This community and it’s collections are organized using the University of Waterloo's Faculties and Academics structure. In this structure:

  • Communities are Faculties or Affiliated Institutions
  • Collections are Departments or Research Centres

Research outputs are organized by type (eg. Master Thesis, Article, Conference Paper).

New collections following this structure will be created UPON REQUEST .

Recent Submissions

  • The Liftable Mapping Class Group 

    Ghaswala, Tyrone (University of Waterloo, 2017-07-19)
    Broadly, this thesis lies at the interface of mapping class groups and covering spaces. The foundations of this area were laid down in the early 1970s by Birman and Hilden. Building on these foundations, there has been a ...
  • Waiting Time Distributions in the Preemptive Accumulating Priority Queue 

    Fajardo, Val Andrei; Drekic, Steve (Springer, 2017-03-01)
    We consider a queueing system in which a single server attends to N priority classes of customers. Upon arrival to the system, a customer begins to accumulate priority linearly at a rate which is distinct to the class to ...
  • Analytic Combinatorics in Several Variables: Effective Asymptotics and Lattice Path Enumeration 

    Melczer, Stephen (University of Waterloo, 2017-06-26)
    The field of analytic combinatorics, which studies the asymptotic behaviour of sequences through analytic properties of their generating functions, has led to the development of deep and powerful tools with applications ...
  • Contributions to the Theory of Radicals for Noncommutative Rings 

    Madill, Blake (University of Waterloo, 2017-06-20)
    We consider several radical classes of noncommutative rings. In particular, we provide new results regarding the radical theory of semigroup-graded rings, monomial algebras, and Ore extensions of derivation type. In ...
  • On a general mixed priority queue with server discretion 

    Fajardo, Val Andrei; Drekic, Steve (Taylor & Francis, 2016-10-01)
    We consider a single-server queueing system which attends to N priority classes that are classified into two distinct types: (i) urgent: classes which have preemptive resume priority over at least one lower priority class, ...
  • Controlling the workload of M/G/1 queues via the q-policy 

    Drekic, Steve; Fajardo, Val Andrei (Elsevier, 2015-06-01)
    We consider a single-server queueing system with Poisson arrivals and generally distributed service times. To systematically control the workload of the queue, we define for each busy period an associated timer process, ...
  • A model for deceased-donor transplant queue waiting times 

    Drekic, Steve; Stanford, David A.; Woolford, Douglas G.; McAlister, Vivian C. (Springer, 2015-01-01)
    In many jurisdictions, organ allocation is done on the basis of the health status of the patient, either explicitly or implicitly. This paper presents a self-promoting priority queueing model for patient waiting times which ...
  • Hierarchical Task Recognition and Planning in Smart Homes with Partial Observability 

    Wang, Dan (University of Waterloo, 2017-06-12)
    Older adults with cognitive impairment have significantly burdened their families and the society due to costly caring and waste of labors. Developing intelligent assistant agents (IAAs) in smart homes that can help those ...
  • Towards Understanding and Improving Code Review Quality 

    Kononenko, Oleksii (University of Waterloo, 2017-06-12)
    Code review is an essential element of any mature software development project, it is key to ensuring the long-term quality of the code base. Code review aims at evaluating code contributions submitted by developers before ...
  • Continuous Affect Recognition with Different Features and Modeling Approaches in Evaluation-Potency-Activity Space 

    Shang, Zhengkun (University of Waterloo, 2017-06-08)
    Emotions are an essential part of human social interactions. By integrating an automatic affect recognizer into an artificial system, the system can detect humans’ emotions and provide personal responses. We aim to build ...
  • Computational Methods in Finance Related to Distributions with Known Marginals 

    Memartoluie, Amir (University of Waterloo, 2017-05-30)
    Model uncertainty and the dependence structures of various risk factors are important components of measuring and managing financial risk, such as market, credit and operational risks. In this thesis we provide a systematic ...
  • Assessing Binary Measurement Systems Using Targeted Verification with a Gold Standard 

    Severn, Daniel Ernest (University of Waterloo, 2017-05-19)
    Binary Measurement Systems (BMS) are used to classify objects into two categories. Sometimes the categories represent some intrinsically dichotomous characteristic of the object, but sometimes continuous or even multidimensional ...
  • A Dynamic Risk-Based Access Control Approach: Model and Implementation 

    Savinov, Sergey (University of Waterloo, 2017-05-18)
    Access control (AC) refers to mechanisms and policies that restrict access to resources, thus regulating access to physical or virtual resources of an information system. AC approaches are used to represent these mechanisms ...
  • Efficient Pointer Analysis of Java in Logic 

    Thiessen, Rei (University of Waterloo, 2017-05-16)
    Points-to analysis for Java benefits greatly from context sensitivity. CFL-reachability and k-limited context strings are two approaches to obtaining context sensitivity with different advantages: CFL-reachability ...
  • Geometrical frustration and static correlations in hard-sphere glass formers 

    Charbonneau, Benoit; Charbonneau, Patrick; Tarjus, Gilles (American Institute of Physics, 2013-03-28)
    We analytically and numerically characterize the structure of hard-sphere fluids in order to review various geometrical frustration scenarios of the glass transition. We find generalized polytetrahedral order to be correlated ...
  • Geometrical Frustration and Static Correlations in a Simple Glass Former 

    Charbonneau, Benoit; Charbonneau, Patrick; Tarjus, Gilles (American Physical Society, 2012-01-18)
    We study the geometrical frustration scenario of glass formation for simple hard-sphere models. We find that the dual picture in terms of defects brings little insight and no theoretical simplification for the understanding ...
  • Computing with Multi-Row Intersection Cuts 

    Xavier, Alinson Santos (University of Waterloo, 2017-05-16)
    Cutting planes are one of the main techniques currently used to solve large-scale Mixed-Integer Linear Programming (MIP) models. Many important cuts used in practice, such as Gomory Mixed-Integer (GMI) cuts, are obtained ...
  • Dimensional dependence of the Stokes-Einstein relation and its violation 

    Charbonneau, Benoit; Charbonneau, Patrick; Jin, Yuliang; Parisi, Giorgio; Zamponi, Francesco (American Institute of Physics, 2013-10-28)
    We generalize to higher spatial dimensions the Stokes-Einstein relation (SER) as well as the leading correction to diffusivity in finite systems with periodic boundary conditions, and validate these results with numerical ...
  • Multimaterial Mesh-Based Surface Tracking 

    Da, Fang; Batty, Christopher; Grinspun, Eitan (Association for Computing Machinery, 2014-07-01)
    We present a triangle mesh-based technique for tracking the evolution of three-dimensional multimaterial interfaces undergoing complex deformations. It is the first non-manifold triangle mesh tracking method to simultaneously ...
  • Regional Time Stepping for SPH 

    Goswami, Prashant; Batty, Christopher (The Eurographics Association, 2014)
    This paper presents novel and efficient strategies to spatially adapt the amount of computational effort applied based on the local dynamics of a free surface flow, for classic weakly compressible SPH (WCSPH). Using a ...
