#### Sparse Polynomial Interpolation and Testing

(University of Waterloo, 2016-03-03)

Interpolation is the process of learning an unknown polynomial f from some set of its evaluations. We consider the interpolation of a sparse polynomial, i.e., where f is comprised of a small, bounded number of terms. Sparse ...

#### Modeling and Managing Longevity Risk: Models and Applications

(University of Waterloo, 2016-07-20)

With the threat of longevity risk to the insurance industry becoming increasingly apparent in recent years, insurers and reinsurers are concerned about how to better model and manage longevity risk. However, modeling and ...

#### FACES OF MATCHING POLYHEDRA

(University of Waterloo, 2016-09-30)

Let G = (V, E, ~) be a finite loopless graph, let
b=(bi:ieV) be a vector of positive integers. A
feasible matching is a vector X = (x.: j e: E)
J
of nonnegative
integers such that for each node i of G, the sum of ...

#### Stability of Nonlinear Functional Differential Equations by the Contraction Mapping Principle

(University of Waterloo, 2016-08-29)

Fixed point theory has a long history of being used in nonlinear differential
equations, in order to prove existence, uniqueness, or other qualitative properties
of solutions. However, using the contraction mapping ...

#### Resource Provisioning for Web Applications under Time-varying Traffic

(University of Waterloo, 2016-01-14)

Cloud computing has gained considerable popularity in recent years. In this paradigm, an organization, referred to as a subscriber, acquires resources from an infrastructure provider to deploy its applications and pays for ...

#### A Taylor polynomial expansion line search for large-scale optimization

(University of Waterloo, 2016-08-29)

In trying to cope with the Big Data deluge, the landscape of distributed computing has changed. Large commodity hardware clusters, typically operating in some form of MapReduce framework, are becoming prevalent for ...

#### Approximately Optimum Search Trees in External Memory Models

(University of Waterloo, 2016-05-16)

We examine optimal and near optimal solutions to the classic binary search tree problem of Knuth. We are given a set of n keys (originally known as words), B_1, B_2, ..., B_n and 2n+1 frequencies. {p_1, p_2, ..., p_n} ...

#### Floating Bodies with Surface Tension

(University of Waterloo, 2016-08-18)

Capillary phenomena have been studied by mathematicians and physicists for hundreds of years. In this thesis, both two-dimensional(2D) and three-dimensional(3D) bodies floating on an unbounded reservoir are studied based ...

#### Bifurcation of Bounded Solutions of Impulsive Differential Equations

(World Scientific Publishing, 2016-12-30)

In this article, we examine nonautonomous bifurcation patterns in nonlinear systems of impulsive differential equations. The approach is based on Lyapunov–Schmidt reduction applied to the linearization of a particular ...

#### Comparing malaria surveillance with periodic spraying in the presence of insecticide-resistant mosquitoes: Should we spray regularly or based on human infections?

(Elsevier, 2016-06-01)

There is an urgent need for more understanding of the effects of surveillance on malaria control. Indoor residual spraying has had beneficial effects on global malaria reduction, but resistance to the insecticide poses a ...
