Technologies for space-based optical interferometry. Gravitational waves are ripples in the curvature of space-time produced by the motion of massive celestial objects. Gravitational waves provide a different kind of information about the universe and their measurement will lead to an entirely new type of astronomy. The quest to detect gravitational waves is entering a new era with the Laser Interferometer Space Antenna (LISA) now under development. LISA is a two billion dollar joint NASA/ESA de ....Technologies for space-based optical interferometry. Gravitational waves are ripples in the curvature of space-time produced by the motion of massive celestial objects. Gravitational waves provide a different kind of information about the universe and their measurement will lead to an entirely new type of astronomy. The quest to detect gravitational waves is entering a new era with the Laser Interferometer Space Antenna (LISA) now under development. LISA is a two billion dollar joint NASA/ESA deep space mission to build a gravitational wave observatory in space. This research will develop Australian technologies critical to the success of LISA and other future deep space missions.Read moreRead less

The project will provide a stimulating, exciting and supportive environment for the training of postgraduate and postdoctoral personnel as well as students at the undergraduate level. It will help to motivate young Australians to pursue their interest in science and engineering.Read moreRead less
Reconfiguring ideology: embodying China's new concepts of heritage in commemorative rituals. Knowledge of China's newly listed and recently revived commemorative rituals is of international significance, and in the era of rising religiosity and civil religion, this study of the state sponsored 'heritage cults' will provide an understanding of the changing terrain of identity, tradition and cultural value in a country that is of crucial importance and increasing significance for Australia.
Foundations of Vision Based Control of Robotic Vehicles. Automated and partially automated robotic vehicles are an emerging technology in society. The safety and performance of such systems depends crucially on their sensing and control algorithms. Vision sensing is one of the few sensor modalities that has the potential to adequately represent the complexity of a real world environment. By providing simple and effective vision based control algorithms this project develops Frontier Technologi ....Foundations of Vision Based Control of Robotic Vehicles.

Vision sensing is one of the few sensor modalities that has the potential to adequately represent the complexity of a real world environment. By providing simple and effective vision based control algorithms this project develops Frontier Technologies for Building and Transforming Australian Industries by enabling a wide range of robotic vehicle applications, including aerial, submersible, and wheeled vehicles.Read moreRead less
Linguistic prehistory in Mainland Southeast Asia: 2000 years of language and culture contact between Austroasiatic and Chamic speakers. The project focuses on the Austroasiatic language groups, Bahnaric, Katuic and Khmer, and one Austronesian, Chamic, which are located in Vietnam, Cambodia and southern Laos. These languages have been in contact for around 2000 years. I will investigate the history of language contact and change, leading to improved understanding of the particular and general pro ....Linguistic prehistory in Mainland Southeast Asia: 2000 years of language and culture contact between Austroasiatic and Chamic speakers. The project focuses on the Austroasiatic language groups, Bahnaric, Katuic and Khmer, and one Austronesian, Chamic, which are located in Vietnam, Cambodia and southern Laos. These languages have been in contact for around 2000 years. I will investigate the history of language contact and change, leading to improved understanding of the particular and general processes involved, and the histories of the languages and their speakers. Outcomes will include improved reconstructions of proto-languages, papers describing in detail the typology and processes of language contact and change, and a substantial monograph on the (pre)history of Mainland Southeast Asia.Read moreRead less
Fluid-structural interactions in high-speed flows. This project aims to perform experiments to measure fluid-structure interaction in hypersonic flows. The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters.

The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters. Accurate prediction of the behaviour and lifetime of structural components subject to these fluid-structural interactions, in which the deformation of the structure induced by the local flow field, can in turn influence this flow field. This coupling can result in damage or even catastrophic structural failure and thus robust design tools must be developed to avoid this.Read moreRead less
Intriguing aerodynamics of bees, hoverflies and beyond. Nature observers have long been fascinated by the elegance, agility and endurance of flying insects, but still human-engineered vehicles fail to match their performance. This project aims to reveal the key physical aspects that allow two different insects to fly so well and thus unlock greater performance for flapping flight vehicles beyond insects.
Rarefied hypervelocity separated flow in the transitional to continuum regimes. The transition regime for low-density flows is a no-man's-land between free-molecular and continuum flow, where the flow behaves differently to the assumptions typically used for modelling either flow type. Bird's direct Simulation Monte Carlo (DSMC) method is typically thought to be the best way of modelling these flows, but has not produced excellent agreement with previous experiments on low-density separated flow ....Rarefied hypervelocity separated flow in the transitional to continuum regimes. The transition regime for low-density flows is a no-man's-land between free-molecular and continuum flow, where the flow behaves differently to the assumptions typically used for modelling either flow type. Bird's direct Simulation Monte Carlo (DSMC) method is typically thought to be the best way of modelling these flows, but has not produced excellent agreement with previous experiments on low-density separated flows, due to computational limitations and lack of knowledge of the flow's internal energy. This proposal is a blind test of the best current DSMC codes against our experiments and a hypersonic continuum code, with the full internal energy state of the flow experimentally quantified for the first time.Read moreRead less
Radiation and Ablation in Rapidly Expanding Flows. The aim of the project is to record the spectra of radiation from a region of rapidly expanding flow representative of the passage of the shock layer on a re-entry capsule from the windward to the leeward surfaces. The significance of this work is that it addresses a critical area of spacecraft where the uncertainties of our design techniques are of the order of 300 per cent in terms of surface heat transfer, and current vehicles have to use lar ....Radiation and Ablation in Rapidly Expanding Flows. The aim of the project is to record the spectra of radiation from a region of rapidly expanding flow representative of the passage of the shock layer on a re-entry capsule from the windward to the leeward surfaces. The significance of this work is that it addresses a critical area of spacecraft where the uncertainties of our design techniques are of the order of 300 per cent in terms of surface heat transfer, and current vehicles have to use large safety factors to ensure survivability. The outputs from the project will be a data base of radiative parameters which should enable accurate models of the flow to be developed, which is expected to facilitate the design of advanced spacecraft with greater safety and reliability, and with lower structural mass.Read moreRead less
