Ostracism and Aggression. Ostracism has been implicated in school shootings (e.g., Columbine) and other violent or anti-social episodes (e.g., Port Arthur shootings). Some argue that ostracism drives individuals toward joining violent extremist groups. Research, however, is mixed: sometimes targets of ostracism correct their behaviors to be more socially acceptable; whereas other times they react with aggression. This research program will investigate the conditions under which ostracism either ....Ostracism and Aggression. Ostracism has been implicated in school shootings (e.g., Columbine) and other violent or anti-social episodes (e.g., Port Arthur shootings). Some argue that ostracism drives individuals toward joining violent extremist groups. Research, however, is mixed: sometimes targets of ostracism correct their behaviors to be more socially acceptable; whereas other times they react with aggression. This research program will investigate the conditions under which ostracism either leads to paths of either pro-social or aggressive reactions. A new virtual reality paradigm will be developed to provide stronger manipulations of ostracism and to assist in discovering the crucial conditions responsible for these paths.Read moreRead less
Ensemble modelling of space-weather drivers. This project aims to develop methods for forecasting the evolution of magnetic fields on the Sun's surface, and to use the results to drive an ensemble of numerical simulations of the evolution of the magnetic field in the overlying atmosphere. The project expects to create a new framework for forecasting the evolution of solar active regions, applying, for the first time, methods established in Numerical Weather Prediction. The expected outcomes are ....Ensemble modelling of space-weather drivers. This project aims to develop methods for forecasting the evolution of magnetic fields on the Sun's surface, and to use the results to drive an ensemble of numerical simulations of the evolution of the magnetic field in the overlying atmosphere. The project expects to create a new framework for forecasting the evolution of solar active regions, applying, for the first time, methods established in Numerical Weather Prediction. The expected outcomes are physics-based prediction of solar atmospheric magnetic field evolution, including explosive eruptions. The results should have significant benefit in improving prediction of extreme space weather events, which pose an increasing threat to our technologically-dependent society.Read moreRead less
Mapping ear morphology to individualised three dimensional audio. The project aims to develop a practical method to derive a listener's individualised Head Related Transfer Functions from two dimensional images of the head and ears. These are essential for generating high-fidelity three dimensional audio. The project will perceptually evaluate and test the proposed system when applied to teleconferencing, surveillance, and navigational guidance.
DYNAMICS OF EARTH'S RADIATION BELTS. Space weather is produced by rapid variations in wave fields and particle populations in near-Earth space, and has many effects. These include damage to spacecraft (causing operational anomalies and loss of service), degrading the performance of GPS, space-ground, HF radio and cable-based networks, and affecting surveillance radars. The core aim of this project is to improve knowledge of the waves and particles causing these effects. While being important to ....DYNAMICS OF EARTH'S RADIATION BELTS.

These include damage to spacecraft (causing operational anomalies and loss of service), degrading the performance of GPS, space-ground, HF radio and cable-based networks, and affecting surveillance radars. The core aim of this project is to improve knowledge of the waves and particles causing these effects. While being important to aerospace engineers, this work also consolidates Australia's international space profile and provides excellent training in this field. Since space weather causes significant radiation exposure to aircraft crew and passengers this work also has broader ramifications.Read moreRead less
Electromagnetic Ion Cyclotron Waves and Magnetosphere Plasma Dynamics. Space weather, manifest as magnetic storms in the Earth's magnetosphere, can severely disrupt and damage advanced technological systems operating in space and on the ground. Spacecraft may experience operational anomalies, pipeline corrosion may eventuate in the long term, and the performance of GPS navigation systems, HF communication systems, mobile phone networks, and surveillance radars, may be degraded. Knowledge of the ....Electromagnetic Ion Cyclotron Waves and Magnetosphere Plasma Dynamics. Space weather, manifest as magnetic storms in the Earth's magnetosphere, can severely disrupt and damage advanced technological systems operating in space and on the ground. Spacecraft may experience operational anomalies, pipeline corrosion may eventuate in the long term, and the performance of GPS navigation systems, HF communication systems, mobile phone networks, and surveillance radars, may be degraded. Knowledge of the near-Earth space environment under which these problems occur is extremely important. This project identifies relevant mechanisms. The research consolidates Australia's international space profile, provides excellent postgraduate training in the field, and contributes to Australia's future technological development.Read moreRead less
Motherese by ear and eye: infant perception of visual prosody. The project breaks new ground in auditory-visual speech processing by using naturally expressive continuous speech to probe how infants perceive visual prosody. A strength of the project lies in its use of breakthrough animation technologies to create a state-of-the-art virtual Talking Mother to enable control of visual speech cues.
Individualisation for 3D Audio. The project aim is to allow the general listener to enjoy high-fidelity 3-D sound over headphones. Such 3-D audio is of paramount importance when inter-personal communication requires situational awareness, (eg search and rescue, fire-fighting, and air traffic control). To achieve this, the project aims to address one of the toughest problems in audio signal processing: deriving high-fidelity 3-D audio headphone filters from photos and/or 3D scans of ears. The pro ....Individualisation for 3D Audio. The project aim is to allow the general listener to enjoy high-fidelity 3-D sound over headphones.

To achieve this, the project aims to address one of the toughest problems in audio signal processing: deriving high-fidelity 3-D audio headphone filters from photos and/or 3D scans of ears. The project plans to address fundamental research questions in statistical shape and data analysis and to perceptually evaluate the 3-D audio methods developed.Read moreRead less
New frontiers for Australian exoplanetary science. There can be few questions more fundamental for a scientist's research to address than 'Is our home here on Earth unique? Or ubiquitous?' This project will undertake world-leading observations using revolutionary new Australian facilities, to enable breakthrough results that bear on this question.
Non-equilibrium reacting shock layers. This project aims is to study the non-equilibrium aerodynamic processes involved in hypervelocity flight. The design of vehicles for high speed flight is critically dependent on modelling the interactions between the flow field and the airframe, and the current lack of understanding is restricting the scope and benefit of viable activities in space. The expected outcomes include the ability to design optimised heat shields and air-frames with minimum mass a ....Non-equilibrium reacting shock layers. This project aims is to study the non-equilibrium aerodynamic processes involved in hypervelocity flight. The design of vehicles for high speed flight is critically dependent on modelling the interactions between the flow field and the airframe, and the current lack of understanding is restricting the scope and benefit of viable activities in space. The expected outcomes include the ability to design optimised heat shields and air-frames with minimum mass and maximum payload, precisely targeting specific flight conditions and vehicle shapes. The prospective benefits include increased productivity and reliability and reduced cost of missions to and from space, and a proliferation of new applications which this understanding will facilitate.Read moreRead less
