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.
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.

This proposed research will be a step towards integration of process design and control, which has been widely recognized as the key to this improvement. The outcomes from this project may be readily implemented in process design practice, and therefore have a direct impact to the Australian and world-wide process industries, helping to build a more efficient and environmental conscious Australian process industries.Read moreRead less
Bayesian Inference for Multivariate Hierarchical Regression Models. This project will develop Bayesian methodology for analysing multivariate regression models. The distribution of each measurement can be discrete or continuous, with the dependence between measurements obtained through the correlation matrix of a Gaussian copula. Model parsimony is obtained by identifying zero elements in the correlation matrix or its inverse and by variable selection on the regression parameters. The results wi ....Bayesian Inference for Multivariate Hierarchical Regression Models. This project will develop Bayesian methodology for analysing multivariate regression models. The distribution of each measurement can be discrete or continuous, with the dependence between measurements obtained through the correlation matrix of a Gaussian copula. Model parsimony is obtained by identifying zero elements in the correlation matrix or its inverse and by variable selection on the regression parameters. The results will be applied to solve problems in finance, health management and marketing. In all these fields multiple observations are often taken per individual or time period and the models need to incorporate measures of dependence and uncertainty.Read moreRead less

Sound and Shape Synthesis Using Tensegrity Particle Systems. Pixar's Toy Story amazed audiences with its computer-generated images, yet the sound was still composed and ?tuned? almost wholly by human hand. In industry, virtual reality systems are increasingly applied to simulation and visualisation but, in general, 'sound? is poorly handled. In this project, we seek to research complex systems that will simulate an object's sound, shape and interaction characteristics in a unified approach. Our ....Sound and Shape Synthesis Using Tensegrity Particle Systems. Pixar's Toy Story amazed audiences with its computer-generated images, yet the sound was still composed and ?tuned? almost wholly by human hand. In industry, virtual reality systems are increasingly applied to simulation and visualisation but, in general, 'sound? is poorly handled. In this project, we seek to research complex systems that will simulate an object's sound, shape and interaction characteristics in a unified approach. Our proposed Tensegrity particle systems generate minimal, stable and robust descriptions of objects in interacting situations. This represents a new and unique approach to the unified representation of multimedia objects with applications in manufacturing and entertainment.Read moreRead less

Our models will represent a major step forward in differentiating between natural processes and anthropological input to present global climate change and will address quantitatively how Australia changed from a continent rich in freshwater to the driest inhabited continent throughout the last 40 million years.Read moreRead less
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
