Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems. Robust and efficient designs for these light-weight vehicles must address the problem of aerodynamic heating and its effect on structural performance and lifing. This project will design and perform first-of-kind experiments that reproduce the complex fluid-thermal-structural interactions representative of those experienced by these aircraft and rockets. We will then use these measurements to assess, validate and improve the current state-of-the-art of simulation and modelling approaches for design.Read moreRead less
Onset Theory: Pushing the design envelope for textile composite structures. This study aims to exploit an innovative physics-based approach to predict the strength of textile composites. This is particularly important in areas such as aircraft design, where drastic weight savings are needed to allow designers to remain competitive in a low-carbon future. Improved theory and design tools will remove conservatism and account for a large part of these weight savings. The new approach is the first t ....Onset Theory: Pushing the design envelope for textile composite structures. This study aims to exploit an innovative physics-based approach to predict the strength of textile composites. This is particularly important in areas such as aircraft design, where drastic weight savings are needed to allow designers to remain competitive in a low-carbon future. Improved theory and design tools will remove conservatism and account for a large part of these weight savings. The new approach is the first to be consistent at all length scales — from atoms to aeroplanes — ensuring relevance for new and evolving composite material systems. A novel understanding of crack initiation in textile laminates is intended to reduce design and certification effort for new aircraft and help to design more efficient airframes at a lower cost.Read moreRead less
Experimental validation of the strain invariant failure theory for carbon/epoxy composites.

Such applications include the aerospace, offshor ....Experimental validation of the strain invariant failure theory for carbon/epoxy composites. The project will be of national and international benefit, through providing a validated, enhanced design capability for advanced composite materials. Greater depth of understanding of such materials will allow more efficient structures to be designed in applications requiring high strength and stiffness, low weight, and resistance to corrosion and fatigue. Such applications include the aerospace, offshore and mining industries. There are, therefore, far-reaching benefits in industries important to Australia. In addition, the reputation of the Australian aerospace research industry will be promoted through a collaborative association with Boeing, a world leader in development of commercial aircraft.Read moreRead less
Approximate proximity for applications in data mining and visualization. Data Mining, pattern recognition and visualization of relational information are all important data analysis techniques in which it is essential to determine which data points are in the vicinity of others. The huge size of the data sets involved and the need for real-time interaction preclude the use of conventional methods for the precise computation of the proximity information required. This project will develop efficie ....Approximate proximity for applications in data mining and visualization. Data Mining, pattern recognition and visualization of relational information are all important data analysis techniques in which it is essential to determine which data points are in the vicinity of others. The huge size of the data sets involved and the need for real-time interaction preclude the use of conventional methods for the precise computation of the proximity information required. This project will develop efficient algorithms and data structures for gathering high-quality approximations of the full proximity information, and will use these innovations as the basis for new, practical tools for visualization, and clustering in data mining.Read moreRead less
Examining scientific, philosophical, and folk perspectives on time=. This project aims to consider three very different physical theories, each of which reconciles quantum mechanics and general and special relativity in a different way. While science is more accessible than ever, we are increasingly faced with a scientific world-view that is antithetical to the way we see the world and experience ourselves in it. This project will consider the tension between the scientific picture of the world ....Examining scientific, philosophical, and folk perspectives on time=. This project aims to consider three very different physical theories, each of which reconciles quantum mechanics and general and special relativity in a different way. While science is more accessible than ever, we are increasingly faced with a scientific world-view that is antithetical to the way we see the world and experience ourselves in it. This project will consider the tension between the scientific picture of the world and our experience of the world, and aims to reconcile the two by bridging the gap between lived experience and scientific findings. The project will provide a range of ways of bridging the tension between these physical theories with our lived experience.Read moreRead less
Trust in a social and digital world. This project aims to provide a systematic and empirically-informed account of the way networks facilitate or hinder knowledge. Distinguishing on-line information from disinformation can be difficult. This task can be greatly assisted by networks of trusted peers, but figuring out who to trust is itself a challenge. Identifying, designing, and facilitating networks of trust is therefore an urgent task. By using the tools of social epistemology, virtue epistemo ....Trust in a social and digital world. This project aims to provide a systematic and empirically-informed account of the way networks facilitate or hinder knowledge. Distinguishing on-line information from disinformation can be difficult. This task can be greatly assisted by networks of trusted peers, but figuring out who to trust is itself a challenge. Identifying, designing, and facilitating networks of trust is therefore an urgent task. By using the tools of social epistemology, virtue epistemology, and network science, this project will identify how individuals should distribute their trust when embedded in epistemically hostile environments.Read moreRead less
The integration of language and society. This project aims to seek associations between social and life-style differences and language structure. All human societies show pervasive similarities and all languages share recurrent features. Viewing society and language as an integrated whole, the project will study related groups in contrasting physical and social environments in PNG, Africa, East Asia, Amazonia and Australia. Inductive generalisations about associations between societal and langua ....The integration of language and society. This project aims to seek associations between social and life-style differences and language structure. All human societies show pervasive similarities and all languages share recurrent features. Viewing society and language as an integrated whole, the project will study related groups in contrasting physical and social environments in PNG, Africa, East Asia, Amazonia and Australia. Inductive generalisations about associations between societal and language parameters (e.g. varying techniques of address relating to articulated kin systems and social hierarchy) aim to provide insight into the human dynamic. Findings should benefit programmes for cultural awareness, language teaching and revitalisation and understanding of multicultural situations.Read moreRead less
Kaytetye and Prosodic Theory. This project addresses a central question about language. How well do we understand the structure of syllables and words? The project aims to examine the Australian language (Kaytetye), the unusual word and syllable structure of which suggests that models of syllable and word structure may require significant revision.

This project addresses a central question about language. How well do we understand the structure of syllables and words? The project aims to examine the Australian language (Kaytetye), the unusual word and syllable structure of which suggests that models of syllable and word structure may require significant revision. The project aims to consider the implications of Kaytetye sound structure for general theories of phonology, and more importantly for ideas about universals in language. The project involves extensive documentation of Kaytetye, which is an endangered language. The project is expected to provide a detailed description of Kaytetye sound structures and articles addressing the implications of these findings for phonological theory.Read moreRead less
