Removal of H₂S, NH₃, and tars from the producer gas of biomass gasification by secondary measures.
(University of Canterbury, 2018)The combination of biomass gasification and Fischer-Tropsch (FT) synthesis is a promising technology for converting biomass to “green” liquid fuel. However, the clean-up process of removing tars, H2S, NH3, and the other ... -
Design considerations for a wearable, bi-modal interface.
(University of Canterbury, 2018)The design of wearable interfaces that mediate interactions between people and the real world requires us to examine these interactions from the perspective of the users. The quality of these interactions is determined by ... -
Long-term behaviour of post-tensioned timber structures
(University of Canterbury, 2018)In 2005, the concept of post-tensioned timber joints, known as the ’Pres-Lam’ system, was firstly proposed and developed at the University of Canterbury. The technology relies on unbonded post-tensioning tendons to provide ... -
Cellular ionic concentration dynamics and wave propagation in spatial media
(University of Canterbury, 2018)In the context of cranial cellular modelling, mathematical techniques have been applied to model oscillations of concentration over time. Models were made for different cell types to match data and known chemical reactions ... -
Semi reproducing kernel hilbert spaces and mixed precision computation.
(University of Canterbury, 2018)Positive definite and conditionally positive definite functions are widely used in interpolation and smoothing problems, particularly when the data is scattered. This thesis concerns such functions and also concerns the ... -
Development of a combined creep-fatigue model for engineering purposes.
(University of Canterbury, 2017)Creep-fatigue damage is caused by reversed loading at elevated temperature, which presents the interaction of fatigue and creep. This behaviour normally spans a wide range of industries, such as aerospace, nuclear and ... -
Structural health monitoring of non-linear hysteretic structures.
(University of Canterbury, 2017)Ensuring life safety is the primary design and maintenance requirement for civil structures designed to be serviceable for a specific lifetime. However, structures subjected to a number of factors may experience quicker ... -
Balancing stakeholder goals in structural fire design of steel-framed buildings.
(University of Canterbury, 2017)When designing a steel-framed building, there are many design options available in terms of meeting the structural fire resistance objectives. Different stakeholders have different opinions about which approach is the most ... -
Using advanced analysis techniques to benchmark forest harvesting systems : a study of the New Zealand forest industry.
(University of Canterbury, 2018)The concept of benchmarking is applied to businesses and industries for the continuous measurement and improvement of production systems and organizational performance. This makes it important to continuously measure and ... -
A decision support framework for selecting feasible coastal protection measures in the Republic of Maldives.
(University of Canterbury, 2017)In the absence of effective coastal protection measures, low-lying countries face inevitable losses from coastal erosion and coastal flooding under future scenarios of sea level rise and climate change. The Republic of ... -
Experimental and analytical tools for rapid development of digital imaging-based elasto-tomography technology
(University of Canterbury, 2018)Breast cancer is the second most common cancer in the world and has the highest cancer mortality rate in women. Presently, 1 of every 4 women carry an increased risk of breast cancer, of which, 6% are below the minimum ... -
Development of a prototype for a real-time variable rate bitumen spray system
(University of Canterbury, 2018)This thesis presents work carried out on the development of a real-time variable rate bitumen spraying system. Sealing roads with bitumen binder and stone chip is used to provide a protective, wear resistant layer and ... -
FEASIBILITY OF TRANSPORTING MAINLAND AGGREGATE TO AUCKLAND
(University of Canterbury, 2005)The Auckland aggregate industry is approaching a crisis situation: conflicting land use and amenity values in both urban and rural areas are relegating quarries to increasingly remote sites. This has lead to higher transport ... -
Duration of earthquake ground motion: Influence on structural collapse risk and integration in design and assessment practice
(2016)Amplitude, frequency content, and duration are widely recognized as the key characteristics of earthquake ground motions that influence structural response. Yet, in current structural design and assessment practice, ... -
Predicting the motion trajectories of a modular snake robot performing various gaits.
(University of Canterbury, 2017)Some studies have demonstrated that snake robots have more advantages than other mobile robots in real-world applications such as search-and-rescue operations and building inspections. A pitch-and-yaw modular snake robot ... -
Tar formation and transformation in steam gasification of biomass in a dual fluidised bed gasifier.
(University of Canterbury, 2017)Gasification is a promising thermos-chemical process that converts biomass into syngas (producer gas). However, the generation of tar compounds during the gasification process limit the subsequent syngas application, since ... -
Pose estimation for feedback control in a snake robot.
(University of Canterbury, 2017)This thesis presents a pose estimation algorithm for a snake robot as a step towards creating a closed-loop controlled snake robot. The University of Canterbury snake robot is being developed for use in urban search and ... -
Prediction of microsleeps from EEG using Bayesian approaches.
(University of Canterbury, 2018)Microsleeps are brief unintentional episodes of sleep-related loss of consciousness up to 15 s during an active task, such as driving. Such episodes of unresponsiveness are of particularly high importance in people who ... -
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 ...
