Stochastic modelling and analysis of spatio-temporal processes with fractal characteristics. Interest has grown in recent years on the derivation of fractal models to represent certain physical phenomena such as diffusion and transport in porous media, oceanic and atmospheric turbulence, climatology, etc. This project focuses on the phenomenon of diffusion on domains with multifractal geometry. Recent advances in harmonic analysis on fractals and our own development of fractional generalized ran ....Stochastic modelling and analysis of spatio-temporal processes with fractal characteristics. Interest has grown in recent years on the derivation of fractal models to represent certain physical phenomena such as diffusion and transport in porous media, oceanic and atmospheric turbulence, climatology, etc. This project focuses on the phenomenon of diffusion on domains with multifractal geometry. Recent advances in harmonic analysis on fractals and our own development of fractional generalized random fields allow us to formulate a comprehensive program to tackle some key problems including modeling, processing and statistical estimation of fractional diffusion. Advances made in this program will in turn benefit the developments in related scientific fields.Read moreRead less
APEC Cooperation for Earthquake Simulation Visitors Program. This project aims to improve understanding of earthquakes through development of numerical simulation models for the earthquake generation process. Its centerpiece is a major international collaboration, achieved via a visitor exchange program between the headquarters of the APEC Cooperation for Earthquake Simulation in Australia and overseas centres of excellence. Earthquakes are one of the most costly and deadly natural disasters, a ....APEC Cooperation for Earthquake Simulation Visitors Program. This project aims to improve understanding of earthquakes through development of numerical simulation models for the earthquake generation process. Its centerpiece is a major international collaboration, achieved via a visitor exchange program between the headquarters of the APEC Cooperation for Earthquake Simulation in Australia and overseas centres of excellence. Earthquakes are one of the most costly and deadly natural disasters, and APEC member economies have a high earthquake risk. Recent analyses suggest earthquakes may dominate the loss potential in Australia. The complementary research programs offer an opportunity to achieve breakthrough advances in improved methods of earthquake forecasting and hazard quantification.Read moreRead less
Beach groundwater dynamics: measurement and modelling. Beach groundwater is a highly complex, dynamic system interacting with tides, waves and swash. Such interactions affect beach sediment movement and contaminant transport/transformation in coastal aquifers. This project aims to measure and model the groundwater's behaviour at three different types of beaches: sand, gravel and gravel-sand mixed beaches. The study will provide much needed understanding and quantification of the beach groundwate ....Beach groundwater dynamics: measurement and modelling. Beach groundwater is a highly complex, dynamic system interacting with tides, waves and swash. Such interactions affect beach sediment movement and contaminant transport/transformation in coastal aquifers. This project aims to measure and model the groundwater's behaviour at three different types of beaches: sand, gravel and gravel-sand mixed beaches. The study will provide much needed understanding and quantification of the beach groundwater dynamics over a range of time scales. The outcome will help to assess the extent and intensity of mass and momentum exchanges across the beach face, and the resulting effects on beach stability and the fate of contaminants in coastal aquifers.Read moreRead less
A Novel Surface Alloying Technique to Improve the Corrosion and Wear Resistance of Magnesium Alloys. Surface mechanical attrition treatment will be used to generate nanometer-sized grains in the surface layer of engineering magnesium alloys, and therefore activate the surface of this material. Together with the use of efficient activators, the project will develop a novel low temperature surface alloying technique to significantly improve the wear and corrosion resistance of magnesium alloys wi ....A Novel Surface Alloying Technique to Improve the Corrosion and Wear Resistance of Magnesium Alloys. Surface mechanical attrition treatment will be used to generate nanometer-sized grains in the surface layer of engineering magnesium alloys, and therefore activate the surface of this material. Together with the use of efficient activators, the project will develop a novel low temperature surface alloying technique to significantly improve the wear and corrosion resistance of magnesium alloys without changing the substrate properties. Microstructural features and the wear and corrosion resistance of the ultrafine-grained surface layer will be examined. In addition, it may be possible to combine the surface alloying process with the conventional ageing process together in order to save energy.Read moreRead less

This project will establish and consolidate links between leading groups in China and Australia to develop a new and unique multiscale computational model and algorithm for simulating multiphase nonlinear behaviours of the porous media under dynamic loading conditions, and improve technology transfer between the two groups by the mobility of the ARC International Fellow. This will aid Australian geoscience and mining industry, such as in HFR geothermal/UCG energy facility design, construction, risk assessment and production and could help Australia shift away from greenhouse gases and become a world leader in the emerging worldwide HFR geothermal/UCG industry.Read moreRead less
