#### Integral based identification for physiological models

(University of Canterbury. Mathematics and Statistics, 2007)

Recently a model-based protocol has been developed for controlling glucose in the Christchurch ICU which has already had a significant clinical impact. A major part of the development involved an integral-based parameter ...

#### A 3-approximation algorithm for the subtree between phylogenies

(University of Canterbury, 2007)

In this paper, we give a (polynomial-time) 3-approximation algorithm for the rooted subtree prune and regraft distance between two phylogenetic trees. This problem is known to be NP-complete and the best previously known ...

#### Selecting taxa to save or sequence : desirable criteria and a greedy solution

(University of Canterbury, 2007)

Three desirable properties for any method of selecting a subset of evolutionary units (EUs) for conservation or for genomic sequencing are discussed. These properties are: spread, stability, and applicability. We are ...

#### The application of regression trees to detecting multiple structural breaks in the mean of a time series

(University of Canterbury. Dept. of Mathematics and Statistics., 2007)

A non parametric approach is proposed for dating structural breaks whose number and dates of occurrence are a priori unknown. In particular, the case of
level shifts is considered. For the purpose of locating the breakdates ...

#### Nature reserve selection problem : a tight approximation algorithm

(University of Canterbury. Dept. of Mathematics and Statistics, 2007)

The Nature Reserve Selection Problem is a problem that arises
in the context of studying biodiversity conservation. Subject to budgetary
constraints, the problem is to select a set of regions to conserve so that ...

#### Advantages of multivariate analysis of the perception of crowding on the Tongariro Crossing compared with univariate analysis

(University of Canterbury. Mathematics and Statistics, 2007)

Multivariate statistical analysis, in particular generalized additive models, is a very powerful approach used to investigate the significant variables that have an impact on crowding. As shown here in the 2005 visitor ...

#### Maps, chaos, and fractals

(University of Canterbury. Mathematics and Statistics, 2007)

The behaviour and properties of one-dimensional discrete mappings are explored by writing Matlab code to iterate mappings and draw graphs. Fixed points, periodic orbits, and bifurcations are described and chaos is introduced ...

#### The application of the support vector machine to the classification

(University of Canterbury. Mathematics and Statistics, 2007)

A classification technique, known as Support Vector Machine (SVM) is applied to tobacco data from the SYFT technologies Ltd. The SVM is used to classify illegal from others. Decision tree is performed prior to SVM and these ...

#### The stabilized Poincare-Heisenberg algebra: A Clifford algebra viewpoint

(University of Canterbury. Mathematics and StatisticsUniversity of Canterbury. Physics and Astronomy, 2007)

The stabilized Poincare-Heisenberg algebra (SPHA) is the Lie algebra of quantum
relativistic kinematics generated by fifteen generators. It is obtained from imposing stability
conditions after attempting to combine the ...

#### A MATLAB implementation of elliptic curve cryptography

(University of Canterbury. Mathematics and Statistics, 2007)

The ultimate purpose of this project has been the implementation in MATLAB of an Elliptic Curve Cryptography (ECC) system, primarily the Elliptic Curve Diffie-Hellman (ECDH) key exchange. We first introduce the fundamentals ...
