On the Development of NonClassical Mathematics
(University of Canterbury. Mathematics and Statistics, 2013)It is well known that classical theorems, when viewed from a constructive perspective, come apart at the seams. Typically there are crucial assumptions, implicitly made within the classical framework (a result of the ... 
On the Ecology and Restoration of Podocarpus cunninghamii in the Eastern South Island High Country
(University of Canterbury. Forestry, 2010)Podocarpus cunninghamii is an endemic New Zealand conifer that, in prehuman times, formed extensive forest communities across the eastern South Island high country. Anthropogenic disturbances have reduced the distribution ... 
On the effectiveness of channel segregation as a channel allocation method in a variety of cellular structures
(University of Canterbury. Electrical and Computer Engineering., 2000)Channel allocation or assignment problems have been studied intensively in the literature for the last 25 years. Current directions of this work appear to be in the area of selforganizing or distributed allocation ... 
On the existence of topological ovals in flat projective planes
(University of Canterbury. Dept. of Mathematics, 1996)We show that every flat projective plane contains topological ovals. This is achieved by completing certain closed partial ovals, the socalled quasiovals, to topological ovals. 
On the Mutual Information Distribution of OFDMBased Spatial Multiplexing: Exact Variance and Outage Approximation
(University of Canterbury. Electrical and Computer Engineering., 2008)This communication considers the distribution of the mutual information of frequencyselective spatially uncorrelated Rayleigh fading multipleinput–multipleoutput (MIMO) channels. Results are presented for orthogonal ... 
On the nonexistence of 5(24,12,6) and 4(23,11,6) designs
(University of Canterbury. Dept. of Mathematics, 1977)It is shown that 5(24,12,6) and 4(23,11,6) designs cannot exist and that consequently a nontrivial 2(2n+1,n,n1) design can be extended to a 4(2n+3,n+2,n1) design if and only if n=4. 
On the Number of Independent Channels in a Diversity System
(University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Mathematics and Statistics, 2010)In a receive diversity system the use of multiple antennas at one end of the link produces multiple channels. A useful, although illdefined, metric for such a link is the number of independent channels provided. In ... 
On the number of rational points on special families of curves over function fields
(2016)We construct families of curves which provide counterexamples for a uniform boundedness question. These families generalize those studied previously by several authors. We show, in detail, what fails in the argument ... 
On the numerical solution of a functional differential equation pertaining to a wave equation
(University of Canterbury. Dept. of Mathematics, 1990)The numerical solution of the invariant imbedding equation, describing time domain, one dimensional direct scattering from a slab in which the material properties are spatially varying, is considered. It is proven that ... 
On the Probability of Adaptation Error in MIMO Systems
(University of Canterbury. Electrical and Computer Engineering., 2006)In this paper, we are interested in evaluating the probability of adaptation error (PAE) in MIMO systems using adaptive modulation or transmission rate. We attack the problem from two distinct perspectives. Firstly, for ... 
On the problem of patient specific endogenous glucose production in neonates on stochastic targeted (STAR) glycaemic control
(University of Canterbury. Mechanical Engineering, 2013)Background: Stress and prematurity can both induce hyperglycaemia in the neonatal intensive care unit (NICU), which in turn is associated with worsened outcomes. Endogenous glucose production (EGP) is the formation of ... 
On the Statistics of Cognitive Radio Capacity in Shadowing and Fast Fading Environments
(University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Mathematics and Statistics, 2009)In this paper we consider the capacity of the cognitive radio (CR) channel in a fading environment under a “low interference regime”. This capacity depends critically on a power loss parameter, alpha, which governs how ... 
On the Zeolitic Imidazolate Framework8 (ZIF8) Membrane for Hydrogen Separation from Simulated Biomassderived Syngas
(University of Canterbury. Chemical and Process Engineering, 2016)Hydrogen separation from biomassderived syngas is a critical step in the utilization of gasification technology. Compared with the traditional methods, membrane technology provides an effective and lowcost solution for ... 
On using learning curves to evaluate ITS
(University of Canterbury. Computer Science and Software Engineering., 2005)Measuring the efficacy of ITS can be hard because there are many confounding factors: short, wellisolated studies suffer from insufficient interaction with the system, while longer studies may be affected by the students’ ... 
On variant means and applications to ergodic theory and harmonic analysis
(University of Canterbury. Mathematics, 1971)This thesis is concerned with the existence and properties of invariant means on certain Banach spaces and their applications to ergodic theory and harmonic analysis. The principal results obtained are as follows. Let G ... 
On weakly mixing transformation semigroups
(University of Canterbury. Dept. of Mathematics, 1982)A generalization of the classical ergodic mixing theorem is given, valid for arbitrary topological semigroups. Conditions under which the tensor product of two representations has no fixed points are obtained and these ... 
Onchip measurement of protrusive force exerted by single hyphal tips of pathogenic microorganisms
(2016)Invasive growth is a process used by fungi and oomycetes to find sources of nutrients. To study the protrusive forces generated as part of this process, we have developed a LabonaChip platform capable of measuring ... 
Ongoing challenges in physicsbased ground motion prediction and insights from the 20102011 Canterbury and 2016 Kaikoura, New Zealand earthquakes
(2017)This paper presents ongoing challenges in the present paradigm shift of earthquakeinduced ground motion prediction from empirical to physicsbased simulation methods. The 20102011 Canterbury and 2016 Kaikoura earthquakes ... 
One Way or the Other?
(University of Canterbury. Civil and Natural Resources Engineering, 2013)Motivated by the debate over whether busy streets within central city areas should be oneway traffic flow or twoway, a Masters’ project researched how this decision might be best made by local decision makers. The ... 
Ongoing development of a 3D seismic velocity model for Canterbury, New Zealand for broadband ground motion simulation
(University of Canterbury. Civil and Natural Resources Engineering, 2014)This paper presents the ongoing development of a new 3D seismic velocity model of Canterbury, New Zealand. The model explicitly represents the Canterbury sedimentary basin, and other significant geologic horizons, which ...
