Development of a novel electromagnetic groundwater flowmeter
(University of Canterbury, 2021)The concept and implementation of an electromagnetic flowmeter has, until now, remained focused on industrial plant applications and oceanographic measurements. This thesis applies the existing body of electromagnetic ... -
Modelling Vs30 in New Zealand using field measurements, proxy variables, and geophysical methods
(University of Canterbury, 2021)VS30, the time-averaged 30-metre depth shear wave velocity (VS) for vertically propagating seismic shear waves, is among the most common parameters required for characterising sites in the context of geotechnical earthquake ... -
Smart electrode for log assessment and joule heating.
(University of Canterbury, 2021)This thesis presents the investigation into designing the smart electrode system for assessing log properties and/or applying Joule heating. Joule log heating is the process of applying a voltage to a log, generating current ... -
Intercepting landfill leachate for recirculation : an initial assessment of experimental design parameters.
(University of Canterbury, 2021)The primary goal of this research was to begin an understanding of the differences in using leachate removed at different depths in a landfill for leachate recirculation, on the biodegradation of waste. The central ... -
Resonant dual active bridge based battery management system to provide lithium-ion cell balancing.
(University of Canterbury, 2021)This thesis presents the specification, simulation, design, and experimental results of a resonant Dual Active Bridge based Battery Management System. The intention of the Sponsor, Sunshine Solar, was to create a cost-effective ... -
Modelling distribution network through tensor representation in the presence of power electronic devices.
(University of Canterbury, 2021)The development in electronics technology in the last decade has greatly increased the use of power electronic-based non-linear loads. This power electronic equipment consists of power electronic loads, Renewable Energy ... -
Simulation of flow and heat transfer in 3D printable triply periodic minimal surface heat exchangers
(University of Canterbury, 2020)3D printing allows the manufacture of novel processing equipment including heat exchangers. A wide variety of different heat exchanger designs exist, and the usage of each depends on the application for which they are ... -
Aerogels synthesised from Canola seed meal protein: processing-structure-property relationships
(University of Canterbury, 2021)Novel bioaerogels produced via the gelation of protein extracts from canola seed meal (CSM) are described for the first time, adding to the scant collection of aerogels that are derived from plant-based biotechnology. ... -
Novel gear to improve selectivity in the trawling industry
(University of Canterbury, 2021)Trawling is a fish harvesting process that catches many non-target species which derive little income for fishers. Legislation is being adopted by countries including Iceland, Norway, the Faroe Islands, the USA, the United ... -
Using Bayesian growth models to predict grape yield
(University of Canterbury, 2021)Seasonal differences in in vine yield need to be managed to ensure appropriate fruit composition at harvest. Differences in yield are the result of changes in vine management (e.g. the number of notes retained after harvest) ... -
Optical and electrochemical properties of the periodically patterned photoanode.
(University of Canterbury, 2021)The integration of a photoelectrode into a redox flow battery (RFB) enables direct solar charging of the battery. The efficiency of a solar RFB depends on the number of photons that excite the electrons and lead to electron ... -
Seismic performance of glulam frames with buckling restrained braces (BRBs).
(University of Canterbury, 2021)This research investigates the in-plane seismic performance of glulam frames with buckling restrained braces (BRBs) through experimental testing, numerical modelling and design approach development. With the advancement ... -
An examination of numerical models of dry and wet granular flow.
(University of Canterbury, 2021)Granular materials are prevalent in nature and industry. However, the models used in industrial design are not able to predict some of the diverse behaviours displayed by granular materials. One common way to research and ... -
Development of cementitious materials from the magnesium silicate minerals.
(University of Canterbury, 2020)Concrete is the second most-consumed items in the world after water. Although cement only accounts for 10-20% of the concrete's weight, it attributes up to 95% of the total carbon emission. Because of the large amount ... -
Seismic performance of CLT core-wall systems and connections
(University of Canterbury, 2021)The Ph.D. research reported explores the seismic performance of cross-laminated timber (CLT) core- wall systems and their connections. While there is a renewed interest and implementation of timber buildings globally, many ... -
Intelligent personal protection for industrial respirators.
(University of Canterbury, 2021)There is a lack of air monitoring systems for industrial respirator head tops. Therefore, an air monitoring system prototype for a respirator head top was created for a company. This air monitoring system is a real-time ... -
Studying the transition from fossil fuel to renewable generation in hydro dominant electricity systems.
(University of Canterbury, 2021)Climate change is a significant and ever-growing threat to societies around the world. To reduce its consequences, immediate changes to reduce anthropogenic greenhouse gas emissions (GHGs) are needed. A major contribution ... -
Robust texture descriptors and algorithms for micro-calcification detection and breast density estimation in mammograms.
(University of Canterbury, 2021)This thesis proposes, implements and evaluates novel algorithms used for processing and analysing mammograms, with two distinct research aims: microcalcifications (MCs) detection and mammographic density (MD) classification. ... -
Modelling of bubble nucleation and growth in a combusting metal droplet.
(University of Canterbury, 2021)Numerous applications are interested in the use of combusting metal powders such as explosives, propellants, pyrotechnics, and bio-agent defeat. Optimising the performance of these reactions is of great interest to many ... -
Effects of scale and spatial variability on streamflows in NZ Alpine catchments.
(University of Canterbury, 2020)Mountain catchments have high spatial variability, but these catchments are the freshwater resources of the world and will be affected by potential future climate change. In this study the TopNet hydrological model is used ...
