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
Fluid-thermal-structural interactions on high-speed aerospace vehicles. 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 desig ....Fluid-thermal-structural interactions on high-speed aerospace vehicles. 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

This project aims to revolutionise the theory and practice of sensing and monitoring by developing novel Artificial Intelligence and Internet of Things technologies. This project expects to generate new knowledge in the area of Artificial Intelligence of Things by combining sensing, machine learning, and big data analytics. Expected outcomes of this project include novel low-cost sensing methods and new hybrid machine learning models for predictive sensory data analytics. This should provide significant benefits, such as substantially reduced operating and service costs and improved accuracy for real-time monitoring in the fields where cheap-to-implement and easy-to-service monitoring systems over large geographical areas are imperative.Read moreRead less
Privacy-preserving data processing on the cloud. This project aims to address the current lack of privacy of user data processed by common cloud computing web servers, including email, business data, and confidential files. This project aims to develop new techniques in cryptography. The anticipated outcome is a suite of practical tools enabling common cloud computing processing operations such as search, statistical analysis, and multi-user access control, to be performed efficiently while pres ....Privacy-preserving data processing on the cloud. This project aims to address the current lack of privacy of user data processed by common cloud computing web servers, including email, business data, and confidential files. This project aims to develop new techniques in cryptography. The anticipated outcome is a suite of practical tools enabling common cloud computing processing operations such as search, statistical analysis, and multi-user access control, to be performed efficiently while preserving the data privacy. These tools should provide significant benefits to the privacy of cloud users, as well as financial and reputation benefits to the IT industry, by significantly reducing the likelihood of massive user data privacy breaches in the event of a cyber-hacking attack on the cloud server.Read moreRead less

Taming the uncertainty in trajectory data. This project aims to develop effective and efficient methods to manage large scale uncertain trajectory data. It provides individuals, business, government and social groups the ability to explore significant uncertain trajectories and their patterns, for important usages in location based services, logistic, transportation and tourism.
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. The project aims to consider the implications of Kaytetye sound structure for general theories of phonology, and more importantly for ideas about uni ....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. 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
