Automatic alignment and comparison of petri dish images containing cell colonies : submitted to the Institute of Information & Mathematical sciences in partial fulfillment of the requirements for the degree of Master of Information Science in Software Engineering at Massey University
This work proposes a novel approach comprising of a chain of algorithms, for comparing, matching and aligning pairs of cell colony images taken at different stages on a Petri dish. The objective is to provide an assistive tool for microbiologists to quantify the loss or growth of cell colonies on …

Using Domination to Analyze RNA Structures.
… Recently researchers at the Courant Institute of Mathematical Sciences used graph theory to model RNA molecules and provided a database of trees representing possible secondary RNA structures. In this thesis we use domination parameters to predict which trees are more likely to exist in nature as …

Fourier Analysis of Wave Equations
… of the major influential and useful subjects in Mathematical Sciences. In this thesis, I mainly use Fourier analysis and PDE methods to study the solution to an inhomogeneous wave equation on Euclidean spaces. I obtained the existence, uniqueness, and regularity for the solution. In the classical …

Implementing the NCTM Standards in a Traditional Classroom
… It was concluded by the Conference Board of the Mathematical Sciences, National Advisory Committee on Mathematical Education, that the "new math" was never implemented in the classroom even though it was detailed in various textbooks. Evans (1993) reiterated that the realities of implementation …

Gauging a State: Excise Taxation, Practical Mathematics, and Cask Measuring in Seventeenth Century England
This thesis investigates the mathematical developments and the continued use of gauging instruments designed to calculate the contents of wooden barrels for the purposes of collecting excise revenue for the English state. This research situates the work of mathematical practitioners alongside the …

Can I Do Math If I Can't Read? - The Relationship Between Reading and Mathematics Standards of Learning Assessments in One High School In Virginia
How well students perform in mathematics and sciences continues to be a measure of a country's worth (Conference Board of the Mathematical Sciences [CBMS], 2012). Nations that want an educated citizenry have consistently studied ways in which to improve performance in mathematics (Claessens and …

Efficient Structure and Motion: Path Planning, Uncertainty and Sparsity
This thesis explores methods for solving the structure-and-motion problem in computer vision, the recovery of three-dimensional data from a series of two-dimensional image projections. The first paper investigates an alternative state space parametrization for use with the Kalman filter approach to …

Efficient Algorithms for Graph-Theoretic and Geometric Problems
This thesis studies several different algorithmic problems in graph theory and in geometry. The applications of the problems studied range from circuit design optimization to fast matrix multiplication. First, we study a graph-theoretical model of the so called ''firefighter problem''. The …

Splitting schemes for nonlinear parabolic problems
This thesis is based on five papers, which all analyse different aspects of splitting schemes when applied to nonlinear parabolic problems. These numerical methods are frequently used when a problem has a natural decomposition into two or more parts, as the computational cost may then be …

Analyses and Applications of the Peaceman--Rachford and Douglas--Rachford Splitting Schemes
Splitting methods are widely used as temporal discretizations of evolution equations. Such methods usually constitute competitive choices whenever a vector field can be split into a sum of two or more parts that each generates a flow easier to compute or approximate than the flow of the sum. In the …

Multi-target Tracking Using on-line Viterbi Optimisation and Stochastic Modelling
To study and compare the safety of intersection, traffic scientists today typically manually monitor the intersection during several days and count how often certain events such as evasive manoeuvres occur. This is a laboursome and costly procedure. The aim of this thesis is to provide tools that …

Discrete Optimization in Early Vision - Model Tractability Versus Fidelity
Early vision is the process occurring before any semantic interpretation of an image takes place. Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. Some models in early vision are easy to perform inference with---they are tractable. Others …

Higher-Order Regularization in Computer Vision
At the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. To reduce ambiguity and noise in the solution, …

Early Vision Optimization: Parametric Models, Parallelization and Curvature
Early vision is the process occurring before any semantic interpretation of an image takes place. Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. Many of these tasks are formulated as optimization problems and one of the key factors for …
