In-vehicle touchscreens : reducing attentional demands and improving driving performance.
(University of Canterbury, 2021)Touchscreens are increasingly being used in cars, motorcycles, aircraft, ships, and agricultural machinery to access a wide range of vehicle functions. The primary motivation for incorporating touchscreens in vehicles is ... -
Measurement of solid fraction and velocity during granular flow discharge from a silo.
(University of Canterbury, 2021)Granular flows are abundant in nature as well as industry extending from coffee powder and pills to energy production. For these products to be affordable, large scale granular flows are required in the process to provide ... -
Recycling and rheology of poly(lactic acid) (PLA) to make foams using supercritical fluid
(AIP Publishing, 2021)Biodegradable plastics are thought to be the possible directions in managing plastic pollutions. Unfortunately, they are not recycled in most countries since they are designed to decompose even though recycling is a more ... -
Modelling multidimensional wave propagation effects in geotechnical site response analysis by incorporating physics-based ground motion simulations and soil heterogeneity.
(University of Canterbury, 2021)The overarching goal of this dissertation is to improve predictive capabilities of geotechnical seismic site response analyses by incorporating additional salient physical phenomena that influence site effects. Specifically, ... -
Exterior reinforced concrete joints with low axial load under seismic loading.
(University of Canterbury, 1972)This report is concerned with the exterior beam-column joints of reinforced concrete frames with low axial load when subjected to high intensity cyclic loading such as that due to an earthquake. Three beam-column units ... -
Behaviour under seismic loading of reinforced concrete beam-column joints with anchorage blocks.
(University of Canterbury, 1972)This report deals with the behaviour of beam-column joints of reinforced concrete frames with anchorage blocks. The beam entered one face of the column only and the beam flexural reinforcement was anchored in an anchorage ... -
Improving the reliability of citizen science data
(University of Canterbury, 2021)Citizen science is a growing movement that enables volunteers to help scientists collect and analyse information. Citizen science can solve problems that may, through ordinary methods, be intractable. In the context of ... -
Full waveform tomography for the upper South Island region, New Zealand
(2021)In this paper, we apply Full Waveform Tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert an existing 3-D geophysical velocity model for the upper South Island region, New Zealand. Through ... -

Modelling soil heterogeneity and wave scattering in geotechnical site response analysis
(2020)This study incorporates soil heterogeneity into geotechnical site response analysis to model wave scattering and the spatial variability of earthquake ground motion -
Ground motion simulation validation with explicit uncertainty incorporation for small-magnitude earthquakes
(2021)This study investigates the uncertainty of simulated earthquake ground motions for smallmagnitude events (Mw 3.5 – 5) in Canterbury, New Zealand. 148 events were simulated with specified uncertainties in: event magnitude, ... -
Source modelling insights from ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
(2021)Hybrid broadband ground motion simulation validation has been an ongoing effort in NZ with recent studies focussed on active shallow crustal earthquakes of large magnitude (Mw>7.0) and small magnitude (3.5<Mw≤5.0). Lessons ... -
Osterberg cell pile load test at Styx Mill overbridge
(University of CanterburyDept. of Civil Engineering, University of Canterbury, 2002)A bored pile constructed at the Styx Mill Bridge overpass, SH 1, in Christchurch, was load tested to determine axial compressive capacity. The testing technique involved using the Osterberg Load Cell, or O-cell. This ... -
Sequential Bayesian updating in practice.

Multipurpose reservoir operation management using evolutionary optimisation under uncertainty in water demand and supply.
(University of Canterbury, 2021)Global freshwater resources are under more pressure due to high demand by industrial, recreational, municipal, and agricultural sectors. Additionally, higher standards of living, growing population, and climate variability ... -
Seismic collapse prediction for loss optimisation seismic design (LOSD)
(University of Canterbury, 2021)Loss optimisation seismic design (LOSD) is a performance-based design procedure which aims to introduce a simple, yet reliable, design methodology for the next generation of seismic design codes. A preliminary framework ... -
Numerical study on the structural performance of buckling-restrained braces and end connections
(University of Canterbury, 2021)A buckling-restrained braced frame (BRBF) is a structural bracing system that provides lateral strength and stiffness to buildings and bridges. They were first developed in Japan in the 1970s (Watanabe et al. 1973, Kimura ... -
Species classification on thermal video using a convolutional recurrent neural network.
(University of Canterbury, 2021)This paper proposes a new approach to species surveying, utilising convolutional recurrent neural networks (CRNNs). By using breakthroughs in neural network architectures and designs, as well as modern hardware, new ... -
Validation of NZ small-magnitude ground-motion simulations using complex structural systems
(2021)This study assesses the need to consider complex structural models in ground-motion simulation validation. It develops a novel statistical framework to quantify the proportion of the differences in structural responses ...
