Modulating factors of intracellular calcium dynamics in vascular smooth muscle cell : a numerical study
(University of Canterbury, 2016)The prevalence of diabetes, a metabolic disorder characterized by hyperglycemia, is increasing rapidly worldwide. According to the world health organization (WHO), almost 422 million people in the world have diabetes. ... 
Characterising and modelling urban runoff quality for improved stormwater management
(University of Canterbury, 2016)Runoff from impermeable urban roof, road and carpark surfaces are key contributors of sediment and heavy metals to urban waterways, causing acute and chronic adverse effects on the aquatic ecosystem. Characterisation of ... 
A smalltalk queueing network simulator
(University of Canterbury, 1989)This report gives complete documentation for a working implementation of a discrete, event driven Smalltalk80 modelling context described in Goldberg and Robson "Smalltalk80: The Language and its Implementation". It also ... 
Development of electrocatalysts for the oxygen evolution reaction in alkaline water electrolysis.
(University of Canterbury, 2016)With the ever depleting oil resources around the world, an alternative transportable and storable fuel is required for the future. Water electrolysis is one method of producing hydrogen (an alternative fuel) that does not ... 
Carburized ethylene pyrolysis tubes : an analysis of the relationship between microstructure, creep performance, and magnetic response.
(University of Canterbury, 2016)High alloy FeCrNi austenitic stainless steels have become the industry standard alloys for use in ethylene pyrolysis furnaces in the petrochemical industry. Each pyrolysis furnace contains a large array of vertically ... 
An unmanned aerial vehicle for autonomous forestry cutover edge survey.
(University of Canterbury, 2016)A proof of concept unmanned aerial system capable of navigating the edge deﬁned by the boundary of forest and cutover has been developed. Following gathering of low altitude imagery of forest cutover edges, two image ... 
The difficulty of constructing a leaflabelled tree including or avoiding given subtrees
(University of Canterbury, 1995)Given a set of trees with leaves labelled from a set L, is there a tree T with leaves labelled by L such that each of the given trees is homeomorphic to a subtree of T? This question is known to be NPcomplete in general, ... 
Tree representations of nonsymmetric groupvalued proximities
(University of Canterbury, 1999)Let X be a finite set and let d be a function from X x X into an arbitrary group Q. An example of such a function arises by taking a tree T whose vertices include X, assigning two elements of Q to each edge of T ( one for ... 
Experimental and theoretical analysis of hybridization
(University of Canterbury, 2006)We develop new heuristics and an exact algorithm for calculating the amount of hybridization between two rooted binary phylogenetic trees. Calculating the minimum number of hybridization events is NPhard, but essential ... 
Random autocatalytic networks
(University of Canterbury, 2004)We determine conditions under which a random biochemical system is likely to contain a subsystem that is both autocatalytic and able to survive on some ambient 'food' source. Such systems have previously been investigated ... 
A nonlinear model of sizestructured populations with applications to cell cycles
(University of Canterbury, 2006)The SharpeLotkaMcKendrick (or von Foerster) equations for an agestructured population, with a nonlinear term to represent overcrowding or competition for resources, are considered. The model is extended to include a ... 
Shape Based Image Retrieval
(University of Canterbury, 2000)A new technique is proposed for representing shape features for the purpose of image retrieval. This project defines the properties of this representation, and implements software that extracts the relevant features from ... 
Traditional Database Implementations in HyperCard
(University of Canterbury, 1988)This project attempts to evaluate the viability of performing one particular computer application in the HyperCard environment. It examines in a nonempirical fashion the benefits and advantages of using HyperCard for the ... 
Cyclic permutations and evolutionary trees
(University of Canterbury, 2002)Given a tree T with leaf set X, there are certain ways of arranging the elements of X in a circular order so that T can be embedded in the plane and 'preserve' this ordering. We investigate some new combinatorial ... 
Reconstructing minimal rooted trees
(University of Canterbury, 1999)For a set T of rooted binary leaflabelled trees, we present an algorithm that finds all of the minorminimal trees that are compatible with T. The running time of this algorithm is polynomial up to the number of trees with ... 
Applications of porous inorganicorganic hybrid solid in membrane reactors and catalysis for hydrogen production.
(University of Canterbury, 2016)Hydrogen based energy system is considered to be a promising solution to address the energy shortage and environment pollution issues. Due to the increasing demand of hydrogen, different processes have been developed to ... 
Queueing Models With Finite and Infinite Buffering Capacity : A Comparative Study
(University of Canterbury, 1991)Queueing theory offers a large variety of techniques that can be used in performance modelling of computer systems and data communication networks. The diversity of assumptions causes that the numerical results, obtained ... 
Optimising hashing functions with genetic algorithms
(University of Canterbury, 1991)Genetic algorithms (aka GA's) are a robust global search strategy that ignore local minima and irrelevant parameters, suitable for large search spaces. It is based on an analogy with natural evolution and survival of the ... 
Mawd: A Collaborative Analysis Tool
(University of Canterbury, 1995)Video analysis is a powerful tool for studying human interactions. Transcribing video footage into usable and understandable data is tedious and time consuming. This report gives an overview of evaluation in RCI and CSCW, ... 
Two further links between MP and ML under the Poisson model
(University of Canterbury, 2003)Maximum parsimony and maximum likelihood are two contrasting approaches for reconstructing phylogenetic trees from sequence and character data. We establish analytic links between these methods (extending connections reported ...
