Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels ....Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels, reducing material and manufacturing costs without compromise to safety and performance - an immense benefit for the myriad engineered products or structures that feature flow over a deformable surface.

Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective o ....Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective of reducing drag by adhering a compliant skin to the surface. While the correct choice of compliance relies upon understanding very complex flow-structure dynamics, the resulting technology is simple, robust and has low capital and maintenance costs. Clearly, drag reduction reduces fuel costs and lower fuel consumption is environmentally beneficial. Read moreRead less
Assessing the determinants and consequences of safety climate in the maritime industry. This project will examine the predictors and outcomes of safety climate in the Australian maritime industry. Findings from this project will be used to improve safety policies, regulations and practices that aim to minimise the number of accidents and incidents in Australian waters.
DEVELOPMENT OF NEW NONLINEAR CONTROLLERS FOR TRAJECTORY TRACKING AND PATH-FOLLOWING OF UNDERACTUATED OCEAN VEHICLES. Trajectory tracking control and path-following of underactuated ocean vehicles are not only of theoretical challenging but also important practice. This project is firstly to develop methodologies to design full-state feedback controllers to force the underactuated ocean vehicles including surface ships and underwater vehicles with off-diagonal terms in their system matrices to tr ....DEVELOPMENT OF NEW NONLINEAR CONTROLLERS FOR TRAJECTORY TRACKING AND PATH-FOLLOWING OF UNDERACTUATED OCEAN VEHICLES. Trajectory tracking control and path-following of underactuated ocean vehicles are not only of theoretical challenging but also important practice. This project is firstly to develop methodologies to design full-state feedback controllers to force the underactuated ocean vehicles including surface ships and underwater vehicles with off-diagonal terms in their system matrices to track reference trajectories generated by virtual vehicles, and to follow a predefined path with a desired forward speed. Secondly, we develop methods to design observers to estimate the unmeasured states (velocities) of the vehicles and incorporate with the full-state feedback controllers to have output-feedback observer-based controllers. Lastly, the proposed control design methods are extended to a certain class of underactuated mechanical systems.Read moreRead less

Large-scale maps of the universe: Enabling wide-field science with the Australian Square Kilometre Array Pathfinder and the Square Kilometre Array. Observational capabilities in astronomy continue to make great advances across the electromagnetic spectrum. The first truly global facility for radio astronomy will be the Square Kilometre Array (SKA), an international $2.5 billion project scheduled for deployment between 2015 and 2020, for which the proposed Australian site has been short-listed.

Observational capabilities in astronomy continue to make great advances across the electromagnetic spectrum. The first truly global facility for radio astronomy will be the Square Kilometre Array (SKA), an international $2.5 billion project scheduled for deployment between 2015 and 2020, for which the proposed Australian site has been short-listed. The Australian SKA Pathfinder (ASKAP) is a next generation radio telescope that is on the strategic pathway towards the staged development and deployment of the SKA. By refining the ASKAP technology and enabling its scientific success we address the national strategic goal of ensuring Australia's technological and scientific readiness for the SKA.Read moreRead less
Peering through the Dark Ages with the Murchison Widefield Array. There is one large gap in our understanding of the early evolution of the universe, namely, when did the first sources of light appear?

The MWA will therefore generate large volumes of scientific data before 2012, the expected date of the international decision that will determine whether Australia or South Africa is to host the SKA. The early science results from the MWA will showcase the excellence of the Australian site for radio astronomy and play a significant strategic role in Australia's bid to attract the SKA, as an international mega-science project to Australia, with its benefits to Australian science, industry and society.Read moreRead less
