Factors influencing shelter in the Woodhill protection strip.
(University of Canterbury, 2018)Woodhill Forest, situated on the west coast of the Auckland region, is directly exposed to strong westerly winds coming from the Tasman Sea. To protect the 41km long Pinus radiata forest, a protective strip of trees has ... -
Exploring opportunities for bio-oil within the New Zealand forestry industry.
(University of Canterbury, 2018)For any forest harvesting operations, either chainsaws or barsaws in harvesting heads are pivotal tools for felling and processing the trees. These cutting chains can only run on the bar if they are lubricated to avoid ... -
The influence of harvest systems on sediment delivery on the Moutere gravels.
(University of Canterbury, 2018)Fine sediment suspended in waterways is one of the most significant pollutants associated with New Zealand plantation forests, adversely impacting the quality of downstream aquatic ecosystems, and tarnishing public perception ... -
The uptake and barriers of geospatial technologies in New Zealand’s forest management sector.
(University of Canterbury, 2018)Geospatial technologies have developed rapidly in recent decades and can provide detailed, accurate data to support forest management decisions. Commonly used technologies include Global Positioning System (GPS), Geographic ... -
Interaction between structural walls, flooring slabs and gravity frames in reinforced concrete buildings.
(University of Canterbury, 2018)Reinforced concrete (RC) wall structures are generally relied to perform adequately in resisting the lateral forces during strong earthquake ground motions. However, recent earthquakes have indicated that several RC ... -
Using immersive technologies to support food-based education.
(University of Canterbury, 2019)The use of Virtual Reality (VR) technology, combined with 360 degree images and videos, provides an opportunity for teachers to bring students into the classroom, even when they are not there. The possibility of immersing ... -
The implications of log taper on the expected difference of JAS scaling to 3D scale in New Zealand.
(University of Canterbury, 2018)As a result of the strong price and demand trends observed in the export market, the importance of value recovery from log exports is emphasised by suppliers/owners. Two methods of analysis were used for the duration ... -
Estimating winch-assist utilisation using GPS tracking.
(University of Canterbury, 2018)Winch-assist systems have become increasingly common in New Zealand as the drive to mechanise forest operations increases, with the aim of reducing accidents and improving the productivity of tree felling on steep slopes. ... -
Hybrid growth models for Eucalyptus globoidea and E. bosistoana : explaining within and between site variability.
(University of Canterbury, 2019)Plantation forests play a major role in satisfying many forestry needs such as demand for wood and different ecosystem services, which are projected to increase in the future. In New Zealand, the plantation forestry industry ... -
Reconstruction of overhead electrical infrastructure for dynamic line rating using vehicle-mounted LiDAR
(University of Canterbury, 2018)Dynamic Line Rating allows for better utilisation of overhead electrical infrastructure by dynamically determining the current carrying capacity in real-time. It is implemented by combining measurements of the ... -
Biological treatment of industrial strength clopyralid in wastewaters : biodegradation & toxicity.
(University of Canterbury, 2019)Pesticides are used worldwide to increase crop production and to remove unwanted weeds. In New Zealand, clopyralid (3,6 dichloro-2-pyridinecarboxylic acid) is one of the most widely used pesticides to control broadleaf ... -
Optimising power system reserve for contingencies while considering response times.
(University of Canterbury, 2019)This thesis develops an optimisation formulation for the efficient procurement of reserve. The formulation explicitly accounts for delay and ramp rates in reserve response, and the effect they have on keeping the grid ... -
The effect of residential property redevelopment on urban forest dynamics in Christchurch, New Zealand.
(University of Canterbury, 2019)As a global phenomenon, many cities are undergoing urban renewal to accommodate rapid growth in urban population. However, urban renewal can struggle to balance social, economic, and environmental outcomes, whereby economic ... -
Design and analysis of a climbing robot for window cleaning.
(University of Canterbury, 2019)With the spread of skyscrapers with large areas of glass windows, robotic cleaners, which can replace and so protect people from the risk of falling, have been seen as a viable option as robotic technology becomes more and ... -
Development of an assessment method for seismic damage to gravity waste water pipes.
(University of Canterbury, 2019)This thesis documents the development and demonstration of an assessment method for analysing earthquake-related damage to concrete waste water gravity pipes in Christchurch, New Zealand, following the 2010-2011 Canterbury ... -
Integrating building information modelling and geographic information systems for characterising urban risk and resilience — a proposed geospatial workflow.
(University of Canterbury, 2019)The development of Digital City technologies to manage and visualise spatial information has increasingly become a focus of the research community, and application by city authorities. Traditionally, the Geographic Information ... -
Improving Virtual Reality safety precautions with depth sensing.
(University of Canterbury, 2019)Virtual Reality (VR) technology provides a computer-generated three-dimensional environment, in which the user can interact with virtual objects in real time and walk naturally with the locomotion techniques. However, ... -
Improved vertex skinning algorithm based on dual quaternions.
(University of Canterbury, 2019)In character animation, traditional skinning algorithms such as linear blend skinning (LBS) and dual quaternion skinning (DQS) are widely used due to their simplicity and e ciency. However, they both su er from ... -
Control and measurement of the cell-culture oxygen environment for an improved cancer model.
(University of Canterbury, 2019)Cancer is a very heterogeneous disease that effects millions worldwide. A common challenge in drug efficacy trials is that widely used cancer models largely lack many attributes that are needed to mimic in-vivo behaviour, ... -
Design, testing and simulation of grip ‘n’ grab ratcheting, tension-only devices for seismic energy dissipation systems.
(University of Canterbury, 2018)This thesis details the development of a ratcheting, tension-only mechanism for use with seismic energy dissipation systems, known as the Grip 'n' Grab (GNG). The development is taken from initial design concepts through ...
