  • Defining a phylogenetic tree with the minimum number of r-state characters 

    Bordewich, M.; Semple, C. (University of Canterbury. Mathematics and Statistics, 2015)
    Semple and Steel (2002) showed that if T is a phylogenetic X-tree and C is a collection of r-state characters that defines T , then |C| >[(n 􀀀 3)/(r - 1)], where n = [X]. In this paper, we show that, provided n is ...
  • Counting phylogenetic networks

    We give approximate counting formulae for the numbers of labelled general, treechild, and normal (binary) phylogenetic networks on n vertices. These formulae are of the form 2 γnlogn+O(n) , where the constant γ is 32 ...
  • What proportion of the small-scale owners' estate in the North Island is likely to be harvested?

    The small-scale forest estate, much of which was planted in the 1990s, will provide an increasing proportion of New Zealand’s harvest volumes over the next decade. However there are questions about the proportion of ...
  • Revisiting Al-Samaw'al’s table of binomial coefficients: Greek inspiration, diagrammatic reasoning and mathematical induction 

    Bajri, S.; Hannah. J.; Montelle, C. (University of Canterbury. Mathematics and Statistics, 2015)
    In a famous passage from his al-Bahir, al-Samaw'al proves the identity which we would now write as (ab)^n = a^n b^n for the cases n = 3; 4. He also calculates the equivalent of the expansion of the binomial (a + b)^n for ...
  • Electrochemical stability of carbon-supported gold nanoparticles in acidic electrolyte during cyclic voltammetry 

    Steven, J.T.; Golovko, V.B.; Johannessen, B.; Marshall, A.T. (University of Canterbury. Chemical and Process Engineering, 2015)
    Cyclic voltammetry has been used to assess the electrochemical stability of gold nanoparticle-based electrocatalysts with differing initial particle size distributions in sulphuric acid electrolyte. The electrochemically ...
  • Numerical modelling of the droplet vaporization for design and operation of liquid-pulsed CVD 

    Boichot, R.; Krumdieck, S. (University of Canterbury. Mechanical Engineering, 2015)
    This article presents an approach for modeling the vaporization of droplets of solvent and precursor mixture under vacuum in the pulsed-pressure CVD process. The pulsed direct liquid injection apparatus with ultrasonic ...
  • An algorithm for constructing a k-tree for a k-connected matroid 

    Brettell, N.; Semple, C. (University of Canterbury. Mathematics and Statistics, 2015)
    For a k-connected matroid M, Clark and Whittle showed there is a tree that displays, up to a natural equivalence, all non-trivial k-separations of M. In this paper, we present an algorithm for con- structing such a tree, ...
  • Wood quality assessment of Pinus radiata (radiata pine) saplings by dynamic mechanical analysis 

    Sharma, M.; Brennan, M.; Chauhan, S.S.; Entwistle, K.M.; Altaner, C.M.; Harris, P.J. (University of Canterbury. School of Forestry, 2015)
    The use of dynamic mechanical analysis was explored as a possible method of screening for wood quality in breeding programmes. Viscoelastic properties along the grain of wood from 18-month-old Pinus radiata saplings were ...
  • Dose-Response Analysis Using R 

    Ritz, C.; Baty, F.; Streibig, J.C.; Gerhard, D. (University of Canterbury. Mathematics and Statistics, 2015)
    Dose-response analysis can be carried out using multi-purpose commercial statistical software, but except for a few special cases the analysis easily becomes cumbersome as relevant, non-standard output requires manual ...
  • Systematic ground motion observations in the Canterbury earthquakes and region-specific non-ergodic empirical ground motion modeling 

    Bradley BA (University of Canterbury. Civil and Natural Resources Engineering, 2015)
    This paper presents an examination of ground motion observations from 20 near-source strong motion stations during the most significant 10 events in the 2010-2011 Canterbury earthquake to examine region-specific systematic ...
  • An integrated approach: managing resources for post-disaster reconstruction

    Pons, D.J.; Pons, A.D.; Pons, A.J. (University of Canterbury. Mechanical Engineering, 2014)
    A novel conceptual theory is developed for the beta decay and electron capture processes, based on the specific non-local hidden-variable (NLHV) design provided by the Cordus theory. A new mechanics is sketched out for the ...
  • Annihilation mechanisms 

    Pons, D.J.; Pons, A.D.; Pons, A.J. (University of Canterbury. Mechanical Engineering, 2014)
