Determining prices for radiata pine clearwood
(University of Canterbury, 1984)Due to the widespread practise of pruning radiata pine trees in New Zealand there will be a substantial amount of timber free of knots to sell in the future. This timber is called "clearwood". A method is presented for ... -
Seismic performance of dowel-type connections in tall timber buildings.
(University of Canterbury, 2019)The PhD research reported in this thesis explores the seismic performance of dowel-type connections in (tall) timber buildings. The research was in part motivated by the fact that connection design in design codes ... -
Quantifying the effect of individual heterogeneity in epidemic spread on a network.
(University of Canterbury, 2021)The common brushtail possum is an introduced species that, over the last 150 years, has caused significant damage to New Zealand’s native flora and fauna. Moreover, brushtail possums are one of the major wildlife reservoirs ... -
The performance of timber-framed load-bearing gypsum plasterboard walls subjected to two-sided fire exposure.
(University of Canterbury, 2021)Gypsum plasterboard lined timber-framed walls are commonly used in construction and provide excellent fire resistance. When these walls are required to perform a load-bearing function, fire resistance is generally assessed ... -
A theoretical and experimental investigation of prestressed cylindrical shell roofs
(University of Canterbury, 1966)This thesis deals with the experimental and theoretical analysis of cylindrical shells that are prestressed within the curved surface. An existing solution to the D.K.J. equation is presented and extended so that ... -
Assessing technology for detection, mitigation, and simulation of concussive rugby impacts.
(University of Canterbury, 2020)Traumatic brain injury (TBI) represents a major health issue for children and adolescents. Neuroimaging techniques in concordance with animal models have suggested the developing brain has a different response to concussive ... -
Ultrasonic transmission imaging
(University of Canterbury, 1978)The problem of imaging cross sections of opaque bodies by means of ultrasonic transmissions is considered. Images are computed from measurements of ultrasonic propagation delay times through the body section. The grey ... -
The reactions of coal in a high intensity electric arc
(University of Canterbury, 1971)The aim of the project reported here was to develop an efficient means of converting coal to acetylene, with a view to using the acetylene for a New Zealand -based plastics industry. When the project was begun in 1967 coal ... -
Seismic performance assessment of a base isolated building.
(University of Canterbury, 2020)Recent studies have demonstrated the practical usage of the Pacific Earthquake Engineering Research Performance-Based Earthquake Engineering (PEERPBEE) framework to quantify performance measures, such as monetary losses and ... -
Design and evaluation of techniques to improve user comfort during prolonged use of virtual reality.
(University of Canterbury, 2020)Virtual Reality (VR) has become a consumer technology, and as such has spread to include many different applications at work, home, school and play, for multiple kinds of users. However, using conventional immersive ... -
Ultra-high temperature electrolysis of molten oxides : titanium extraction from ironmaking slag.
(University of Canterbury, 2020)This thesis is a comprehensive study of ironmaking slag produced from titanomagnetite concentrates and its use as a molten electrolyte for titanium metal extraction. The electrolysis of ironmaking slag, the largest by-product ... -
Using mixed reality for asymmetric remote collaboration in a room-scale workspace.
(University of Canterbury, 2020)The primary goal of this thesis is to use Mixed Reality (MR) technology to enhance remote collaboration in a room-scale workspace. One of the fundamental requirements for remote collaborative system design is to help the ... -
The mechanical behaviour of gravel-rubber mixtures : insights from dem numerical investigations.
(University of Canterbury, 2021)An innovative 'Eco-rubber geotechnical seismic-isolation foundation system’ has been proposed to help address New Zealand’s waste tyres problem. This foundation system combines gravels with granulated tyre chips to take ... -
Segmentation of substantia nigra and red nucleus in MRI images : application to Parkinson’s disease.
(University of Canterbury, 2021)Accurate segmentation of substantia nigra (SN) and red nucleus (RN) is challenging, yet important for understanding health problems like Parkinson’s disease (PD). This thesis proposes robust algorithms to segment SN and ... -
Sediment management for catchments with hydropower dams under uncertainty in future projections.
(University of Canterbury, 2020)The sustainability of hydropower reservoirs in catchments undergoing rapid development in the Mekong River Basin depends on the projected level of sedimentation. Excess sedimentation of reservoirs can be mitigated by using ... -
Network level defenses for software-defined internet of things.
(University of Canterbury, 2020)Internet of Things (IoT) has become a point of attraction to the industry and academia recently. The IoT is becoming popular because of the lesser prices and easy availability of smart devices. The IoT network consists of ... -
Electrode–skin impedance compensation for improved bioelectrical signal acquisition
(University of Canterbury, 2020)Stroke is the third leading cause of disability worldwide, commonly removing a subject’s independence. However, physical therapy can assist a subject in regaining their lost functionality. Modern physical therapy is ... -
Vibrational response of structures due to external dynamic loading : in particular, investigations of the behaviour of cross braced water towers in earthquakes
(University of Canterbury, 1971)A method of predicting the seismic response of cross braced elevated water tower structures, using an electronic digital computer to integrate the equations of motion of mathematical models of the system, is presented. The ... -
A study of reinforced concrete shell roofs employing observations on model structures
(University of Canterbury, 1964)This thesis deals with the analysis of cylindrical and shallow doubly curved shells. particular emphasis is placed on shells supported on elastic beams at their edges and on multi-shell structures. -
A geospatial and economic analysis of potential for afforestation in Canterbury, New Zealand
(University of Canterbury, 2020)Canterbury’s plantation forest area has been declining due to land use change. The future size of the forestry industry is uncertain and without afforestation is predicted to be significantly smaller. A reduction in the ...
