Wave Climate in the Southern Great Barrier Reef. Sea surface roughness has a major influence on global climate modelling. This project will provide a better understanding of the variability of sea waves in coastal waters. New technology of HF ocean radar can map wave fields over coastal waters and thus fill a gap between the open ocean satellite measurements and the point measurements from wave buoys. In this project we will improve the analysis of the radar echoes to produce sea wave spectra, a ....Wave Climate in the Southern Great Barrier Reef. Sea surface roughness has a major influence on global climate modelling. This project will provide a better understanding of the variability of sea waves in coastal waters. New technology of HF ocean radar can map wave fields over coastal waters and thus fill a gap between the open ocean satellite measurements and the point measurements from wave buoys. In this project we will improve the analysis of the radar echoes to produce sea wave spectra, and evaluate focussing of waves by complex currents on the continental shelf to help improve wave forecasting in coastal waters. The HF radar will be used to experimentally test current theories of wind wave spreading.Read moreRead less
High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators wi ....High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators will apply their extensive knowledge in thin-walled tubular structures to establish the most economical means of designing high strength bollards. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less
Precise Atmospheric Density Correction Model Using Space Tracking Data for Accurate Debris Surveillance and Collision Warning. Our project will build new atmospheric density correction models (ADCMs) for accurate prediction of debris object and satellite orbits. This research will have tremendous impacts on realizing unaided debris laser ranging. An order of magnitude accuracy improvement to the ADCMs will lead to a significant breakthrough in space object tracking. The benefits of this research ....Precise Atmospheric Density Correction Model Using Space Tracking Data for Accurate Debris Surveillance and Collision Warning. Our project will build new atmospheric density correction models (ADCMs) for accurate prediction of debris object and satellite orbits. This research will have tremendous impacts on realizing unaided debris laser ranging. An order of magnitude accuracy improvement to the ADCMs will lead to a significant breakthrough in space object tracking. The benefits of this research are: it will put Australia in a leading position in the world on ADCM study; to maintain Australia's leading role in space surveillance and greatly enhanced operational capability & efficiency of Australian space tracking systems; and to contribute significantly to the space environment info management, e.g. accurate collision warning and space junk tracking.Read moreRead less
Long-term changes in Mackay Whitsunday water quality and connectivity between coral reefs and mangrove ecosystems. Declining water quality is implicated in the degradation of near-shore Great Barrier Reef (GBR) ecosystems. The goal of this project is to provide a definitive answer to the question of how GBR water quality has changed since European arrival (pre-1860). Using novel geochemical proxies in long-lived coral cores and innovative remote sensing techniques, we will develop quantitative h ....Long-term changes in Mackay Whitsunday water quality and connectivity between coral reefs and mangrove ecosystems. Declining water quality is implicated in the degradation of near-shore Great Barrier Reef (GBR) ecosystems. The goal of this project is to provide a definitive answer to the question of how GBR water quality has changed since European arrival (pre-1860). Using novel geochemical proxies in long-lived coral cores and innovative remote sensing techniques, we will develop quantitative histories of water quality and mangrove distribution change. This project will deliver the first integrated assessment of how coastal water quality and associated ecosystems have varied historically, which will be immediately applicable for long-term management of coastal ecosystems lining the GBR.Read moreRead less
Development of Nuclear Quadrupole Resonance Methods and Technology to Enhance the Detection of Explosives and Other Contraband. This project will develop new methods and technology for the detection of explosives and other compounds using Nuclear Quadrupole Resonance. This technique is of great importance to aviation security and the military and is particularly relevant to the priority goal of 'Safeguarding Australia'.

This project will develop new methods and technology for the detection of explosives and other compounds using Nuclear Quadrupole Resonance. This technique is of great importance to aviation security and the military and is particularly relevant to the priority goal of 'Safeguarding Australia'. The Industry partner has licensing contracts with major x-ray manufacturers and system integrators to integrate this technology. These investigations should yield improvements in the signal to noise ratio, false alarm rates and the spatial discrimination of targets. This work will lead to significant increases in the value of the technology and open up new areas of commercialization.Read moreRead less
Emerging futures: transit-oriented development as a strategy for dealing with urban sprawl and congestion in South East Queensland. This project will examine the phenomenon of urban sprawl in SEQ to understand how sprawl is impacting on architectural and urban environments. Transit-oriented devlopment (TOD)is seen as a global strategy for inhibiting urban sprawl, but the benefits of TOD are not yet measured in Australia.

This project will examine the phenomenon of urban sprawl in SEQ to understand how sprawl is impacting on architectural and urban environments. Transit-oriented devlopment (TOD)is seen as a global strategy for inhibiting urban sprawl, but the benefits of TOD are not yet measured in Australia. With increased density around railway infrastructure the threat to public safety is raised. This study will examine the wider issues of TOD with respect to four inter-disciplinary areas: architecture and urban design, urban planning, security, counter-terrorism and threat management, transport strategy and insitutional management.Read moreRead less
