The aim of this project is to provide accurate, rapid and cost-effective ‘health checks’ for bridges. Transportation infrastructures are subject to continuous degradation due to the environment, ageing and excess loading. This project plans to develop a vehicle equipped with sensors as a mobile sensing platform to catch the dynamic interaction between the vehicle and the bridge. The interaction information would be used to assess the health of the bridge infrastructure through substructuring techniques. The expected output of this project would enable managers to monitor the structural conditions and provide an economical infrastructure asset management scheme to protect the structure and human lives.Read moreRead less
Motorway management system integrating safety, efficiency & sustainability. This project aims to develop a motorway management system that holistically optimises motorway safety, efficiency, and sustainability via intervening the traffic flow dynamics. In the current practice of motorway traffic flow management, safety, efficiency, and sustainability are fundamentally connected but separately managed as they are modeled by distinct methodologies. The new system is based on a proposed traffic flo ....Motorway management system integrating safety, efficiency & sustainability. This project aims to develop a motorway management system that holistically optimises motorway safety, efficiency, and sustainability via intervening the traffic flow dynamics. In the current practice of motorway traffic flow management, safety, efficiency, and sustainability are fundamentally connected but separately managed as they are modeled by distinct methodologies. The new system is based on a proposed traffic flow theory which includes a microscopic model for safety analysis and a derived macroscopic model for efficiency and sustainability analysis. This theory can be used to resolve the above-mentioned long unsettled challenge and significantly improve our motorway performance.Read moreRead less
Synthetic energy absorbing composite for improved track performance. This project aims to study the performance of a novel synthetic energy absorbing composite (SEAC) placed beneath the railway ballast to minimise degradation. The use of coal wash and steel slag blended with shredded recycled rubber as SEAC constituents is environmentally beneficial. The role of SEAC with respect to impact and cyclic loads will be assessed through extensive geotechnical laboratory and numerical analysis.

Reconfigurable Conformal Antenna Arrays for Broadband in the Sky Networks. The project aims to develop the theory and technology for a novel type of antennas, namely, reconfigurable conformal antenna arrays, for future broadband in the sky networks (BISNets). BISNets are essential to providing digital services to users on the move and in remote areas.

The project aims to develop the theory and technology for a novel type of antennas, namely, reconfigurable conformal antenna arrays, for future broadband in the sky networks (BISNets). BISNets are essential to providing digital services to users on the move and in remote areas. The antenna would be conformal to the surface of the mounting platform, and its elements would be reconfigured in situ to generate the optimum radiation characteristics to suit the radio environment. It is expected that the project would advance the scientific knowledge of space-borne wireless communications and sensing in general, and antennas in particular, and significantly enhance the performance and reduce the cost of BISNets.Read moreRead less
Cementitious gel: the missing link in understanding the ageing of built infrastructure. Exposure of built reinforced concrete infrastructure to coastal environments causes premature ageing, unplanned remediation and reduced safety. Enhanced forecasting, achieved by advanced methods, including Helium Ion Microscopy and modeling interactions between cement gel, chloride and water, will deliver proactive management of ageing assets.
A complex systems approach to granular rheology: interconnecting topology, stability, dynamics and function. The response of granular materials (e.g. soil, rocks) to applied stresses and strains will be characterised in detail. Information mined from experimental and simulation tests will be used to develop robust predictive models of granular behaviour, crucial for effective earthquake mitigation as well as greener mining and construction technologies.

The project will demonstrate its devices in a wireless communication system operating at unprecedented data rates of over 100 Gb/s. These could transform terrestrial and satellite communication systems and propel Australia to the forefront of wireless communications.Read moreRead less
