Summary
Advanced thermal protection systems to enable Mars return missions. This project aims to advance the modelling of spacecraft heat shield performance to enable future returns to Earth from Mars, where vehicles will encounter heating loads an order of magnitude higher than Lunar returns. Survival depends on sacrificial heat shields which intentionally lose mass through ablation to form a protective layer. Currently, this process cannot be predicted accurately leading to compromised safety, excessi ....Advanced thermal protection systems to enable Mars return missions. This project aims to advance the modelling of spacecraft heat shield performance to enable future returns to Earth from Mars, where vehicles will encounter heating loads an order of magnitude higher than Lunar returns. Survival depends on sacrificial heat shields which intentionally lose mass through ablation to form a protective layer. Currently, this process cannot be predicted accurately leading to compromised safety, excessive weight, and increased mission cost. The expected outcome is an ablation model for vehicle design which, for the first time, is based on experiments with a realistic aerodynamic flow. The significance and benefit of this project is its potential to make ambitious missions such as a Mars return feasible.Read moreRead less
Understanding the dynamics of the dark universe. This project aims to test theories of dark matter and dark energy with the ultimate goal of understanding the properties of the dark components of the universe and how those properties can be explained by new fundamental physics. The project will use two astronomical datasets, the Dark Energy Survey, with measurements of approximately 3000 supernovae, and the Dark Energy Spectroscopic Instrument, with measurements of 30 million galaxies. By compar ....Understanding the dynamics of the dark universe. This project aims to test theories of dark matter and dark energy with the ultimate goal of understanding the properties of the dark components of the universe and how those properties can be explained by new fundamental physics. The project will use two astronomical datasets, the Dark Energy Survey, with measurements of approximately 3000 supernovae, and the Dark Energy Spectroscopic Instrument, with measurements of 30 million galaxies. By comparing theoretical models to this combination of data the project will help to determine whether dark energy changes with time, measure detailed clustering properties of dark matter, and test advanced theories of gravity.Read moreRead less

Slicing dead stars to reveal the origin of heavy elements in the Universe. This project aims to improve our understanding of how massive stars forge heavy elements like oxygen, that are key to life. It will use state-of-the-art spectrographs on Australian and Chilean telescopes to observe the ashes of dead stars, and test recent theoretical models. Expected outcomes include spectral maps of young supernova remnants, new observational constraints for theoretical models of massive stars and core-c ....Slicing dead stars to reveal the origin of heavy elements in the Universe. This project aims to improve our understanding of how massive stars forge heavy elements like oxygen, that are key to life. It will use state-of-the-art spectrographs on Australian and Chilean telescopes to observe the ashes of dead stars, and test recent theoretical models. Expected outcomes include spectral maps of young supernova remnants, new observational constraints for theoretical models of massive stars and core-collapse supernovae, and innovative visualization solutions for complex 3D datasets. This project is expected to largely refine our grasp of the formation of heavy elements in the Universe, and thus provide significant cultural benefit in enhancing our understanding of mankind's cosmic origin in the heart of massive stars.

A Method for Analysis of Complexity in Cognitive Processes: Applications to Prediction of Industrial Workloads. The project will develop a method for analysis of cognitive complexity in human and animal cognition. It will contribute to basic research because it will enable equivalences and relative complexities of cognitive functions to be determined, independent of content or methodology. It will have applications to education, because it enables complexities of concepts to be recognised and a ....A Method for Analysis of Complexity in Cognitive Processes: Applications to Prediction of Industrial Workloads. The project will develop a method for analysis of cognitive complexity in human and animal cognition. It will contribute to basic research because it will enable equivalences and relative complexities of cognitive functions to be determined, independent of content or methodology. It will have applications to education, because it enables complexities of concepts to be recognised and appropriate pedagogies determined. It also has application to human factors, especially industrial performance and decision making. It will advance on currrent methods because it enables workload to be analysed and predicted, so that it can be factored into job and system design. Read moreRead less
A fast comparative method for historical linguistics. Linguists are able to infer ancient histories of languages by a procedure known as the Comparative Method. Its results are used in related studies of human genetic and cultural change. However, the Comparative Method is a manual-only process and thus currently is a bottleneck for the science of unravelling the human past. This project aims to overcome this limitation and significantly accelerate linguistic discovery, by combining recent advan ....A fast comparative method for historical linguistics. Linguists are able to infer ancient histories of languages by a procedure known as the Comparative Method. Its results are used in related studies of human genetic and cultural change. However, the Comparative Method is a manual-only process and thus currently is a bottleneck for the science of unravelling the human past. This project aims to overcome this limitation and significantly accelerate linguistic discovery, by combining recent advances in computational language processing, statistics and cultural-evolutionary modelling. By producing innovative mathematical means for rapidly discovering ancient language relationships, it will enable a breakthrough in our capacity to uncover human linguistic, genetic and cultural heritage worldwide.Read moreRead less
