Vertical Wind Tunnel for Prediction of Rocket Flight Dynamics
(University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Mechanical Engineering, 2016)A customized vertical wind tunnel has been built by the University of Canterbury Rocketry group (UC Rocketry). This wind tunnel has been critical for the success of UC Rocketry as it allows the optimization of avionics ... 
Changing importances of professional practice competencies over an engineering career
(University of Canterbury. Mechanical Engineering, 2015)The profession depends on its practitioners developing management and leadership skills to achieve good client outcomes and robust, reliable products or services, delivered by profitable, ethically run engineering businesses. ... 
NARX models for simulation of the startup operation of a singleshaft gas turbine
(University of Canterbury. Mathematics and StatisticsUniversity of Canterbury. Mechanical Engineering, 2016)In this study, nonlinear autoregressive exogenous (NARX) models of a heavyduty singleshaft gas turbine (GT) are developed and validated. The GT is a power plant gas turbine (General Electric PG 9351FA) located in ... 
Applicability of 'GelPush' sampling technique for sandy layer
(University of Canterbury. Civil and Natural Resources Engineering, 2015)In recent years, "GelPush" "GP" sampling has become popular as one of the high quality soil sampling techniques. The GP is able to collect high quality samples by using a lubricant gel that reduces the friction between ... 
Parallel Implementation of the Box Counting Algorithm in OpenCL
(University of Canterbury. Computer Science and Software Engineering, 2015)The Box Counting algorithm is a wellknown method for the computation of the fractal dimension of an image. It is often implemented using a recursive subdivision of the image into a set of regular tiles or boxes. Parallel ... 
Cascaded techniques for improving emphysema classification in computed tomography images
(University of Canterbury. Computer Science and Software Engineering, 2015)The previous studies demonstrated the effectiveness of the multifractal based method for the classification of histopathological cases by calculating the local singularity coefficients of an image using different intensity ... 
Recycling disaster waste: Feasibility, method and effectiveness
(University of Canterbury. Civil and Natural Resources Engineering, 2016)Recycling is often employed as part of a disaster waste management system. However, the feasibility, method and effectiveness of recycling varies between disaster events. This qualitative study is based on literature ... 
Hereditary convexity for harmonic homeomorphisms
(University of Canterbury. Dept. of Mathematics and Statistics, 2015)We study hereditary properties of convexity for planar harmonic homeomorphisms on a disk and an annulus. A noteworthy class of examples with the hereditary property arises fromenergyminimal diffeomorphisms of an annulus, ... 
Spatial Point Processes and Moment Dynamics in the Life Sciences: A Parsimonious Derivation and Some Extensions
(University of Canterbury. Dept. of Mathematics and Statistics, 2015)Mathematical models of dynamical systems in 6 the life sciences typically assume that biological systems are spatially well mixed (the meanfield assumption). Even spatially explicit differential equation models typically ... 
Analytical Simulation of Seismic Collapse of RC Frame Buildings
(University of Canterbury. Civil and Natural Resources Engineering, 2015)Application of a fibreelement nonlinear modelling technique for seismic collapse capacity assessment of RC frame buildings in comparison with conventional lumped plasticity models is investigated in this paper. Constitutive ... 
Untreated runoff quality from roof and road surfaces in a low intensity rainfall climate
(University of Canterbury. Civil and Natural Resources Engineering, 2016)Sediment and heavy metals in stormwater runoff are key pollutants of urban waterways, and their presence in stormwater is driven by climatic factors such as rainfall intensity. This study describes the total suspended ... 
Tip MotionSensor Signal Relation for a Composite SPM/SPL Cantilever
(University of Canterbury. Mechanical Engineering, 2015)An array of microbeams is a promising approach to increase the throughput of scanning probe microscopes and lithography. This concept requires integrated sensors and actuators which enable individual measurement and control. ... 
Frame Element with Mixed Formulations for Composite and RC Members with Bond Slip. II: Correlation Studies
