Generalized Jacobians and explicit descents
(Mathematics of Computation, 2019)We develop a cohomological description of explicit descents in terms of generalized Jacobians, generalizing the known description for hyperelliptic curves. Specifically, given an integer n dividing the degree of some ... -
Spatial data science: Closing the human-spatial computing-environment loop
(2019)Over the last decade, the term spatial computing has grown to have two different, though not entirely unrelated, definitions. The first definition of spatial computing stems from industry, where it refers primarily to ... -
A structural reliability framework for collapse risk assessment incorporating ground motion duration and response spectral shape
(2015)A structural reliability framework is developed to post-process the results of an incremental dynamic analysis (IDA) and compute a hazard-consistent collapse fragility curve. The ability to produce hazard-consistent ... -
Multiparameter spectral analysis for aeroelastic instability problems
(2017)This paper presents a novel application of multiparameter spectral theory to the study of structural stability, with particular emphasis on aeroelastic flutter. Methods of multiparameter analysis allow the development ... -
Erosion sources and sediment pathways to streams associated with forest harvesting activities in New Zealand.
(2017)Streams and rivers are abundant in our plantation forests and the Forest Industry prides itself on protecting the intrinsic values they provide, including clean water and quality aquatic habitat. In ensuring they remain ... -
Where to next for our sinking city? Opinion piece in the Christchurch Press, 15th August 2014
(University of Canterbury. Civil and Natural Resources Engineering, 2014)OPINION: Associate Professor MARK QUIGLEY, from the University of Canterbury's department of geological sciences, and Dr MATTHEW HUGHES, from its department of civil and natural resources engineering, survey the changing ... -
A Simulation Model to study the performance of the HDLC protocol.
(1984)The aim of this project was to produce a Simula program that will model the ISO HDLC Asynchronous Balanced Mode (ABM) protocol. This program can be used firstly to provide a tool for performance evaluation of the HDLC ... -
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, ... -
Ceramic tiling viewer
(1996)Observing and interacting with multi-thread programs can be difficult for the programmer. Simple input/output (I/O) can become a nightmare when multiple threads read and write simultaneously. A solution would separate the ... -
Identifying X-trees with few characters
(University of Canterbury, 2004)Previous work has shown the perhaps surprising result that, for any binary phylogenetic tree T, there is a set of four characters that define T. Here we deal with the general case, where T is an arbitrary X-tree. We show ... -
Post Disaster Reconstruction Research: An Industry Update
(University of Canterbury. Civil and Natural Resources Engineering, 2008)The Resilient Organisations research programme aims to improve the resilience of New Zealand organisations to major hazard events. Organisations manage, maintain and operate our infrastructure, create our economy and ... -
Smart Grid in a New Zealand Context
(University of Canterbury. Electrical and Computer Engineering, 2012)The following report examines the Smart Grid in the context of New Zealand. It begins by developing a definition for what the Smart Grid actually by looking at various international organisations views. Defining the Smart ... -
Barriers to Post Disaster Reconstruction: Report on Workshop
(Resilient OrganisationsUniversity of Canterbury. Civil and Natural Resources Engineering, 2006)A workshop was held to identify the challenges and barriers to post-disaster reconstruction in New Zealand to help guide research under Objective 3 of the Resilient Organisations project. The workshop brought together ... -
Resourcing the Canterbury Rebuild: Changes and Emerging Themes
(University of Canterbury. Civil and Natural Resources Engineering, 2012)The second quarter of 2012 has seen a clearer plan for the recovery of Christchurch over the next few years. The targeted Government’s agenda involves a $5.5 billion 2012 Government Budget 1 and the creation of a new ... -
Preliminary Results from Organisational Resilience and Recovery Study December 2010
(University of Canterbury. Civil and Natural Resources Engineering, 2010)The Resilient Organisations Research Programme and the University of Canterbury are undertaking a longitudinal study to examine the resilience and recovery of organisations within the Canterbury region following the 4 ...
