Improving the seismic performance of structures with Direction and Displacement Dependent Viscous dampers.
(University of Canterbury, 2017)Modern structures demand greater protection from natural hazards, such as strong winds and severe earthquakes. Structures have traditionally been designed to sustain significant sacrificial damage to absorb and dissipate ... -
Structure and dynamics of lowland podocarp-broadleaved forest in the Central North Island, New Zealand : the effects of different silvicultural regimes on stand structure and tree species composition.
(University of Canterbury, 2017)Podocarp-broadleaved forests and their alliances form one of the largest forest groups in New Zealand and cover an area of approximately 2.9 million hectares. Their vast exploitation and deterioration in the past 150 years ... -
In Silico analysis of flow and dispersion in ordered porous media.
(University of Canterbury, 2017)The work herein investigates exciting new prospects for practical chromatographic systems which may be achieved using the rapidly evolving technology; three-dimensional printing. Previous studies in the literature have ... -
The effect of water infrastructure development on flow regimes and sedimentation in the Mekong floodplains.
(University of Canterbury, 2018)The Mekong floodplains and delta play an important role in poverty and hunger alleviation in Vietnam and Cambodia. Their high agricultural and ecological productivity are largely due to the natural hydrological regime and ... -
Engineering biodegradable materials with bio-inspired topographies.
(University of Canterbury, 2017)Attachment, proliferation and gene expression of anchorage-dependant cells can be influenced by their surroundings, extra-cellular matrix, and the chemistry and morphology of the substrate they adhere to. In-vitro cells ... -
Graphical security modelling and assessment for the internet of things.
(University of Canterbury, 2018)The Internet of Things (IoT) is enabling innovative applications in various domains and offering convenience in different aspects of people’s life. Characterised by the constrained resources, heterogeneous techniques ... -
Optimisation of condenser design on solar desalinators
(University of Canterbury, 2017)PROBLEM Access to fresh and safe drinking water is a major challenge in many countries. A variety of solar desalination technologies exist, which range from passive to highly automated systems. The problem for third-world ... -
Continuous production and supercritical extraction of acetone, butanol and ethanol by Clostridium acetobutylicum fermentation.
(University of Canterbury, 2017)A batch and continuous fermentation of Clostridium acetobutylicum ATCC 824 was tested for the production of acetone, butanol and ethanol. It was found that the batch process with a glucose-based medium supplemented with ... -
Molecular dynamics simulations on the effects of moisture on the interfacial adhesion properties of glass fibre-epoxy composites
(University of Canterbury, 2018)Molecular Dynamics (MD) simulations were used in investigating interface adhesion in glass fibre reinforced polymer composites. Novel contributions were made for; (i ) determining the solubility limit of water in a ... -
Steam gasification of rice husk pellets in a dual fluidized-bed gasifier for hydrogen-rich producer gas
(University of Canterbury, 2018)Experiments were conducted in this study on steam gasification of rice husk pellets (RHP) at a 100 kWth dual fluidized bed (DFB) gasifier, which consists of a circulating fluidized bed (CFB) column and a bubbling fluidized ... -
The sorption of dissolved heavy metals from stormwater: the effect of biofilm, gravel, and two alternative substrates
(University of Canterbury, 2018)Stormwater acts as a major transport pathway for urban contaminants, with heavy metal contaminants of concern primarily being zinc, copper, and lead. In an effort to reduce the environmental impacts of stormwater, a range ... -
Low-damage design of bridge superstructures for accelerated bridge construction
(University of Canterbury, 2018)Many bridges in New Zealand are reaching the end of their service life, some have been damaged in earthquakes and are in need of retrofit or replacement. Expansion of the transport network also constantly necessitates ... -
Development of a portable milking platform for ovine dairy using the TRIZ design methodology
(University of Canterbury, 2018)This project developed a portable sheep milking plant from a 16-unit single aside plant using the TRIZ methodology. This project was completed at Read Industrial Ltd and the Mechanical engineering postgraduate offices. The ... -
Seismic ratcheting of steel low-damage buildings
(University of Canterbury, 2017)During earthquake shaking some structures tend to deform and yield more in one direction than in the other. This phenomenon is sometimes termed “ratcheting” and the displacement demands may become significantly larger than ... -
Flash pyrolysis of biomass for the production of renewable chemicals
(University of Canterbury, 2018)To investigate the methanolysis of biomass, a fluidised bed reactor system was designed, constructed, commissioned and operated to investigate the product distribution during operation up to temperatures of 1000 °C and ... -
Seismic performance evaluation of steel frame building with different composite slab configurations
(University of Canterbury, 2017)Large-scale experimental tests, detailed finite element studies, strut-and-tie studies, and hand approaches are conducted on a number of steel beam-column moment frame sub-assemblies with a composite deck slab subjected ... -
A novel way to measure the rheology of liquids
(University of Canterbury, 2018)Many liquid samples do not easily lend themselves to standard rheometry techniques. Consequently, it is important to find a novel way of measuring the rheology of liquids without using a rheometer. This thesis explores ... -
Seismic ratcheting of rc columns with eccentric gravity loadings and non-symmetric lateral stiffness and strength.
(University of Canterbury, 2017)Structures with different lateral force resistance or different stiffness in both directions due to eccentric gravity loading and/or strength differences may have a tendency to displace more in once direction than the other ... -
Harmonic state estimation : error analysis and optimal location for power quality measurements.
(University of Canterbury, 2017)The harmonic levels in a distribution system are becoming more important as the use of non-linear loads and new technology is increasing. Monitoring of the harmonic levels is important in order to manage them. Direct ... -
Model-based glycaemic control using subcutaneous insulin for in-patients
(University of Canterbury, 2018)Dysregulation of blood glucose (BG) levels can occur due to either the influence of stress hormones and external drugs in the critical care setting or a developed resistance/impairment to glucose regulation as seen in ...
