Mathematics (Faculty of)
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 .

Affect Lexicon Induction For the Github Subculture Using Distributed Word Representations
(University of Waterloo, 2018-11-06)Sentiments and emotions play essential roles in small group interactions, especially in self-organized collaborative groups. Many people view sentiments as universal constructs; however, cultural differences exist in some ... -
The Estimation of Stochastic Models in Finance with Volatility and Jump Intensity
(University of Waterloo, 2018-10-26)This thesis covers the parametric estimation of models with stochastic volatility, jumps, and stochastic jump intensity, by FFT. The first primary contribution is a parametric minimum relative entropy optimal Q-measure ... -
A Variability-Aware Design Approach to the Data Analysis Modeling Process
(University of Waterloo, 2018-10-25)The massive amount of current data has led to many different forms of data analysis processes that aim to explore this data to uncover valuable insights such as trends, anomalies and patterns. These processes support ... -
SURF: Software Update Registration Framework
(University of Waterloo, 2018-10-25)BlockSURF (Blockchain-based Secure Update Registration Framework) or SURF, in short, is a software framework designed to enable developers to build a blockchain-based secure update system which distributes trust over a ... -
Quantifying Location Privacy In Location-based Services
(University of Waterloo, 2018-10-24)Mobile devices (e.g., smart phones) are widely used in people's daily lives. When users rely on location-based services in mobile applications, plenty of location records are exposed to the service providers. This causes ... -
Coordination in a Peer Production Platform: A study of Reddit's /r/Place experiment
(University of Waterloo, 2018-10-24)Understanding the factors causing groups to engage in coordinating behaviour has been an active research area for decades. In this thesis, we study this problem using a novel dataset of crowd behaviour from an online ... -
Designing Efficient Algorithms for Combinatorial Repairable Threshold Schemes
(University of Waterloo, 2018-10-23)Repairable secret sharing schemes are secret sharing schemes where, without the original dealer who distributed the shares, the participants can combine information from their shares to perform a computation that ... -
Multiple Continuous Subgraph Query Optimization Using Delta Subgraph Queries
(University of Waterloo, 2018-10-23)This thesis studies the problem of optimizing and evaluating multiple directed structural subgraph queries, i.e., those without highly selective predicates on the edges or vertices, continuously in a changing graph. Existing ... -
On the optimal CFL number of SSP methods for hyperbolic problems
(Elsevier, 2019-01-01)We show that the theory for strong stability preserving (SSP) time stepping methods employed with the method of lines-type discretizations of hyperbolic conservation laws may result in overly stringent time step restrictions. ... -
On Eulerian orientations of even-degree hypercubes
(Elsevier, 2018-09-01)It is well known that every Eulerian orientation of an Eulerian 2k-edge connected (undirected) graph is strongly k-edge connected. A long-standing goal in the area is to obtain analogous results for other types of connectivity, ... -
Time-consistent mean–variance portfolio optimization: A numerical impulse control approach
(Elsevier, 2018-11-01)We investigate the time-consistent mean–variance (MV) portfolio optimization problem, popular in investment–reinsurance and investment-only applications, under a realistic context that involves the simultaneous application ... -
A lower bound for the two-variable Artin conjecture and prime divisors of recurrence sequences
(Elsevier, 2019-01-01)In 1927, Artin conjectured that any integer other than −1 or a perfect square generates the multiplicative group (Z/pZ)× for infinitely many p. In 2000, Moree and Stevenhagen considered a two-variable version of this ... -
Creating an Emotion Responsive Dialogue System
(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 ... -
On fixed points of self maps of the free ball
(Elsevier, 2018-07-01)In this paper, we study the structure of the fixed point sets of noncommutative self maps of the free ball. We show that for such a map that fixes the origin the fixed point set on every level is the intersection of the ... -
Technological strategies to estimate and control diffusive passage times through the mucus barrier in mucosal drug delivery
(Elsevier, 2018-01-01)In mucosal drug delivery, two design goals are desirable: 1) insure drug passage through the mucosal barrier to the epithelium prior to drug removal from the respective organ via mucus clearance: and 2) design carrier ... -
Applications of Stochastic Control to Portfolio Selection Problems
(University of Waterloo, 2018-10-16)Portfolio selection is an important problem both in academia and in practice. Due to its significance, it has received great attention and facilitated a large amount of research. This thesis is devoted to structuring optimal ... -
Learning Sparse Orthogonal Wavelet Filters
(University of Waterloo, 2018-10-12)The wavelet transform is a well studied and understood analysis technique used in signal processing. In wavelet analysis, signals are represented by a sum of self-similar wavelet and scaling functions. Typically, the wavelet ... -
Multiscale GARCH Modeling and Inference
(University of Waterloo, 2018-10-11)The motivation behind this thesis is the shortage of formal statistical inference methods in the literature for testing whether a time series model is consistent with a sample at multiple sampling frequencies simultaneously. ... -
Towards A Workload-Driven Flow Scheduler For Modern Datacenters
(University of Waterloo, 2018-10-05)Modern datacenters run different applications with various communication requirements in terms of bandwidth and deadlines. Of particular interest are deadlines that are driving web-search workloads e.g. when submitting ... -
Bidirectional Learning in Recurrent Neural Networks Using Equilibrium Propagation
(University of Waterloo, 2018-09-26)Neurobiologically-plausible learning algorithms for recurrent neural networks that can perform supervised learning are a neglected area of study. Equilibrium propagation is a recent synthesis of several ideas in biological ...
