Modelling Virtual Transport Channel for Future Multimedia Heterogeneous Networks. Recent advances in network bandwidth and processing power have led to the emergence of real time multimedia streaming applications and it is expected that such applications will become an even more dominant source of traffic in future computer networks.

Recent advances in network bandwidth and processing power have led to the emergence of real time multimedia streaming applications and it is expected that such applications will become an even more dominant source of traffic in future computer networks. Quality of service studies for real-time applications in high-speed networks, point to the importance of the transport layer functionality in admission control, monitoring end-to-end delays, and network bandwidth adaptability. The project will study, design, develop and analyse a comprehensive model for the virtual transport layer to satisfy the necessary quality of service requirements for the next generation of multimedia-based applications.Read moreRead less
Thulium doped silica-based optical fibres - towards the realisation of an optical amplifier. In the last decade the data capacity of a single optical fibre has grown way beyond all expectations. However, our ability to utilise the available capacity continues to keep pace with any advance. This project has the potential to add substantially to the transmission capacity by developing an optical amplifier at wavelengths which, although available within the fibre, can not currently be utilised. The ....Thulium doped silica-based optical fibres - towards the realisation of an optical amplifier. In the last decade the data capacity of a single optical fibre has grown way beyond all expectations. However, our ability to utilise the available capacity continues to keep pace with any advance. This project has the potential to add substantially to the transmission capacity by developing an optical amplifier at wavelengths which, although available within the fibre, can not currently be utilised. The focus of the project is the study of thulium doped silica-based fibres for amplification in the 1460 to 1530 nm wavelength region. Read moreRead less
Semiconductor Photonic Crystal Devices. Photonic crystals will be a key element of future all-optical ultra-highspeed photonic integrated circuits for telecommunications and signal processing. This project will pioneer new structures capable of manipulating light on integrated photonic chips, based on nano-scale features in semiconductors. This will have a significant impact on Australia's photonics industry.
Combinatorial structures for computer security and communication. Hadamard matrices in their various guises arise many times in the study of reliable communications and secure communications. The aim of this research project is to use the theory of cyclotomy in both fields and rings to find new number theoretic results which will then be used to obtain new with zero or small autocorrelation functions.
The significance of this research is to propose new construction of Hadamard matrices and bloc ....Combinatorial structures for computer security and communication.

The significance of this research is to propose new construction of Hadamard matrices and block designs for computer security and wireless network communication.
We expect some new classes of Hadamard matrices and block designs can be constructed for security and communication applications and several papers would be submitted or published.

Extending the scope of modular analysis for the validation of large systems. The increasing complexity of computer systems has severe implications for verification and validation, especially for critical systems (e.g. medical supervision, avionics mission systems). The standard approach is to build a formal model of the system and automatically analyse its behaviour. Such models can be captured in a modular, high-level description, but the number of states is usually so large as to preclude an ....Extending the scope of modular analysis for the validation of large systems. The increasing complexity of computer systems has severe implications for verification and validation, especially for critical systems (e.g. medical supervision, avionics mission systems). The standard approach is to build a formal model of the system and automatically analyse its behaviour. Such models can be captured in a modular, high-level description, but the number of states is usually so large as to preclude analysis. The modular analysis proposed in this project matches the analysis technique to the structure of the model. Preliminary results are promising and motivate the extension of the technique to a larger class of modular descriptions.Read moreRead less
