    • Oblique decision trees in transformed spaces. 

      Wickramarachchi, Darshana Chitraka (University of Canterbury. Mathematics and Statistics, 2015)
      Decision trees (DTs) play a vital role in statistical modelling. Simplicity and interpretability of the solution structure have made the method popular in a wide range of disciplines. In data classification problems, DTs ...
    • Oblique wave groups in deep water 

      Bryant, Peter John (University of Canterbury. Dept. of Mathematics, 1982)
      Oblique wave groups consist of waves whose straight parallel lines of constant phase are oblique to the straight parallel lines of constant phase of the group. Numerical solutions for periodic oblique wave groups with ...
    • Observation of changes in model-based insulin sensitivity during haemodialysis transitions for critically ill patients 

      Jamaludin, U.K.; Docherty, P.D.; Chase, J.G.; Le Compte, A.J.; Shaw, G.M. (University of Canterbury. Mechanical Engineering, 2012)
      Most critically ill patients exhibit a myriad of symptoms with irregular glycaemic regulation and renal failure contributing to a large proportion of mortality and morbidity. Hence, the effect of dialysis on glycaemic ...
    • Observation of the Incretin Effect in Critically Ill patients 

      Jamaludin, U.; Docherty, P.D.; Chase, J.G.; Preiser, J.C.; Desaive, T.; Shaw, G.M. (University of Canterbury. Mechanical Engineering, 2011)
      The impact of endogenous insulin secretion and its interaction with feeding method (enteral - EN or parenteral – PN) in glycemic control protocols is unknown. This study examines whether there is any evidence for an EN – ...
    • Observed Ground Motions in the 4 September 2010 Darfield and 22 February 2011 Christchurch Earthquakes 

      Bradley, B.A. (University of Canterbury. Civil and Natural Resources Engineering, 2012)
      This paper provides an overview of the salient aspects of the dense array of ground motions observed in the 4 September 2010 Darfield and 22 February 2011 Christchurch earthquakes. Particular attention is given to inferred ...
    • Obtaining forest description for small-scale forests using an integrated remote sensing approach 

      Xu, C.; Manley, B.; Morgenroth, J. (University of Canterbury. School of Forestry, 2015)
    • Obtaining forest description for small-scale forests using an integrated remote sensing approach 

      Xu, Cong (University of Canterbury, 2017)
      The estimated total forest plantation area in New Zealand is approximately 1.70 million ha. Approximately 70% of the plantations with area over 1000 ha are owned by large-scale owners, whose forests undergo regular monitoring ...
    • Off-diagonal 2-4 damping technology using semi-active resetable devices 

      Rodgers, G.W.; Mulligan, K.J.; Chase, J.G.; Mander, J.B.; Deam, B.L.; Carr, A.J. (University of Canterbury. Mechanical Engineering.University of Canterbury. Civil Engineering., 2006)
      Semi-active resetable devices are an emerging and effective method of minimising structural degradation due to environmental loads. Of particular importance in implementing supplemental damping, such as resetable devices, ...
    • Offset Banking in New Zealand: towards sustainable development, with insight from international models 

      Denny, Jemma P Simon Stewart (University of Canterbury. School of Forestry, 2011)
      Biodiversity loss is an important issue for New Zealand: for the domestic environment, economy and society, but also for New Zealand as a member of the international community. Biodiversity offset banking is making an ...
    • Omnidirectional gait generating algorithm for hexapod robot 

      Fielding, Michael (University of Canterbury. Mechanical Engineering, 2002)
      Walking robots have long been proposed as solutions to the problem of mobile machines operating in unstructured and natural environments because they can traverse relatively large obstacles and avoid dangerous or sensitive ...
    • On 4-dimensional elation Laguerre planes admitting simple lie groups of automorphisms 

      Steinke, Günter F. (University of Canterbury. Dept. of Mathematics, 1997)
      This paper concerns 4-dimensional ( topological locally compact connected) elation Laguerre planes that admit large automorphism groups. In particular, it is shown that such a plane is classical if its automorphism group ...
    • On 4-dimensional Minkowski planes with 7-dimensional automorphism group 

      Steinke, Günter F. (University of Canterbury. Dept. of Mathematics, 1993)
      This paper concerns 4-dimensional (topological locally compact connected) Minkowski planes that admit a 7-dimensional automorphism group 𝚺. It is shown that such a plane is either classical or has a distinguished ...
    • On a conjecture of J.C. Butcher and H. Podhaisky 

      Coope, I. D. (University of Canterbury. Department of Mathematics and Statistics, 2006)
    • On a functional equation model of transient cell-growrh 

      Begg, Ronald; Wake, G.C.; Wall, David J. N. (University of Canterbury, 2004)
      A cell-growth model with applications to modelling the size distribution of diatoms is examined. The analytic solution to the model without dispersion is found and is shown to display periodic exponential growth rather ...
    • On a Gaussian approximation to the capacity of wireless MIMO systems 

      Smith, P.; Shafi, M. (University of Canterbury. Electrical and Computer Engineering., 2002)
      In this paper we consider the capacity of a single user MIMO wireless system in a Rayleigh or Ricean fading environment. It is known that a certain central limit theorem exists which states (under certain conditions) ...
    • On a problem of Andersson and Perlman 

      Steel, M.A.; Wood, Graham R. (University of Canterbury. Dept. of Mathematics, 1993)
      We present a simple solution to a problem posed recently by Andersson and Perlman. This solution allows us to find the conditional independence assumptions necessary to permit maximum likelihood estimation of the parameters ...
    • On an inverse problem from magnetic resonance elastic imaging 

      Wall, David J. N.; Olsson, Peter; Van Houten, Elijah E. W. (University of Canterbury. Dept. of Mathematics, 2006)
      The imaging problem of elastography is an inverse problem. The nature of an inverse problem is that it is illconditioned. We consider properties of the mathematical map which describes how the elastic properties of the ...
    • On approximation of optimizing phylogenetic diversity for cluster systems 

      Faller, Beáta; Semple, Charles; Steel, M. A. (University of Canterbury, 2009)
      A basic question in conservation biology is how to maximize future biodiversity as species face extinction. One way to approach this question is by measuring the diversity of a set of species in terms of the evolutiona ...

      Lee, Jong-Suk Ruth (University of Canterbury, 2000)
      The credibility of the final results from stochastic simulation has had limited discussion in the simulation literature so far. However, it is important that the final results from any simulations be credible. To achieve ...
