Impact of Short-circuit Ratio on Grid Integration of Wind Farms - A New Zealand Perspective
(2019)The high wind energy potential sites are increasingly remote from the load centers which create problems in integrating wind power plants into power grids. One of the major issues is the short-circuit radio (SSR) at the ... -
Post-earthquake recovery phase of winery facilities. A case study in the Marlborough area
(2019)New Zealand wine export reached a record of NZ$1.7 billion in 2018. It constitutes an important sector of the economy of the country. Approximately 70% of New Zealand wine is produced in the Marlborough region. In recent ... -
The Impact of Multi-sensory Stimuli on Confidence Levels for Perceptual-cognitive Tasks in VR
(IEEE, 2020)© 2020 IEEE. Supporting perceptual-cognitive tasks is an important part of our daily lives. We use rich, multi-sensory feedback through sight, sound, touch, smell, and taste to support better perceptual-cognitive things ... -
Numerical Study of Nonlinear Self-sustained Thermoacoustic Instability in a Swirling Combustor
(American Institute of Aeronautics and Astronautics, 2020)Self-exited thermoacoustic instability is undesirable in gas turbines and other propulsion systems due to structural vibration, overheating and flame flashback. Such instability is characterized with large-amplitude limit ... -
Spatially Balanced Sampling using the Halton Sequence
(2019)A spatial sampling design determines where sample locations are placed in a study area. The main objective is to select sample locations in such a way that valid scientific inferences can be made to all regions of the ... -
Development of the Arcsecond Pico Star Tracker (APST)
(2016)The second generation star tracker estimates pointing knowledge of the satellite without a-priori knowledge. But star trackers are larger in size, heavier, power hungry and expensive for nanosatellite missions. The Arcsecond ... -
Measuring Linguistic Diversity During COVID-19
(2020)Computational measures of linguistic diversity help us understand the linguistic landscape using digital language data. The contribution of this paper is to calibrate measures of linguistic diversity using restrictions on ... -
WHICH VISUALISATION TOOLS AND WHY? COMPARING PERCEPTIONS OF STUDENT AND PRACTICING DESIGNERS TOWARD DIGITAL SKETCHING
(The Design Society, 2020)Different design tools offer a variety of different benefits to designers at different stages in the design process. Yet, as digital design tools develop, providing more nuanced utility, we observe a challenge for design ... -
Low-cycle fatigue testing on strain-aged steel reinforcing bars
(2020)During earthquakes, steel reinforcing bars in reinforced concrete structures may be subjected to large inelastic deformation in tension and compression as high as 6% strain, eventually leading to low-cycle fatigue failure ... -
Spacecrete: The final frontier for concrete construction
(Concrete NZ, 2019)The eventual construction of infrastructure on the moon and Mars will require innovative solutions in both structural design and material selection. While concrete has been used on Earth in various forms for over 2,000 ... -
Non-linear cyclic response of concrete walls with different transverse reinforcement detailing
(Canadian Society for Earthquake Engineering, 2019)This paper summarizes the results of an experimental campaign carried out to investigate the buckling performance of reinforcing bars in reinforced concrete (RC) structural walls. The post-buckling response of reinforcing ... -
Shake Table Tests of Multiple Non-Structural Elements in a Low–Damage Structural Steel Building
(SPONSE, 2019)The Robust Building Systems (ROBUST) project is aimed at enhancing the seismic resilience of buildings by introducing and validating low-damage concepts for the structural and non-structural elements (NSEs). A three-story, ... -
Thermal Decomposition of Flexible Polyurethane Foams in Air
(2019)The oxidative thermal decomposition of a non-fire retardant and a fire retardant polyurethane foam is investigated over 1 – 60 °C/min of heating rate. From the thermogravimetry results under the oxidative environment of ... -
Multi-modal traffic dynamics of Christchurch CBD
(2020)The urban traffic networks of cities are complex with many transport modes that share and compete for limited road space in the urban landscape. As part of An Accessible City (ACC) framework of Christchurch that was ... -
Analysis of lightning generated over-voltages on voltage regulating devices in distribution system with centralized wind turbine generators
(IEEE, 2018)© 2018 IEEE. The effect of global warming is expected to increase the number of lightning strikes with the capacity to alter the operations of power lines and voltage regulating devices. This problem is exacerbated by the ...
