Fixed and variable-length segment vocoders for very low bitrate speech coding. Reliable and secure voice communication is an important aspect of military and defence operations. In order to reduce the possibility of interception, low power transmitters are normally used for radio communications, where the bandwidth is often very low. Military voice communication, therefore, requires the coding of speech at very low bitrates.

Reliable and secure voice communication is an important aspect of military and defence operations. In order to reduce the possibility of interception, low power transmitters are normally used for radio communications, where the bandwidth is often very low. Military voice communication, therefore, requires the coding of speech at very low bitrates. Our research proposal aims to develop speech coders that can operate at lower bitrates and reproduce speech of high quality and intelligibility. This is highly beneficial to the defence forces of Australia as it will permit the use of high-grade encryption technology to improve the security of transmission.Read moreRead less

This project will create and define generic tools and services to increase the productivity of those involved with the creation, maintenance and use of source material for humanities research. It will provide a pathway to move this infrastructure onto a more sustainable footing and address issues of information overload, authority and quality facing researchers in the networked digital age. This imperative is seen by scholars and representatives of the nation's major collecting institutions as a primary limiting factor in the contemporary research environment. The project will enhance Australia's reputation as a world leader in the development of web-based information infrastructure to support research and scholarship.Read moreRead less
New lattice approach for digital broadband communications. A main limiting factor in supplying future broadband communications is overcoming signal dispersion in the transmission channel. Recent preliminary collaboration by the chief investigators has uncovered a novel approach to this problem based on powerful mathematical lattice theory.

A main limiting factor in supplying future broadband communications is overcoming signal dispersion in the transmission channel. Recent preliminary collaboration by the chief investigators has uncovered a novel approach to this problem based on powerful mathematical lattice theory. The techniques have potential to significantly increase bandwidth and reliability compared to current technologies. This project will use lattice theory to propose, develop, analyse and test new data transmission techniques including joint coding, modulation and equalisation. The research will include theoretical analysis and hardware implementation. The overall aim is to dramatically improve reliability and throughput of data communication systems.Read moreRead less

Australian Women's Archives Project aims to enhance infrastructure for researchers in the field of women's and gender history by constructing appropriate data bases and a range of other electronic sources of information, and by improving the preservation and accessibility of records and archives relevant to this prominent and growing field. Project outcomes will include support for the production of cutting edge academic historical works and simultaneously, the significant contribution of an essential information resource base for Australian women.
The Australian Women's Archives Project employs innovative technologies and adheres to state-of-the-art international standards for electronic management of historical information. The roles of AWAP's Chief Investigators reflect the use of these new forms of information management: CIs both create and utilise the products of each others' collaborative historical research.

Supramolecular assembly in photovoltaic electrode design: Studies of ordered porphyrin/acceptor complexes on polythiophene electrodes. This research outlines an improved way to develop dye-sensitised photovoltaic solar cells for the conversion of sunlight into electricity, by increasing the molecular order of the cell components using host, guest interrelationships. As such, it addresses a problem of international concern 'How to reduce greenhouse gas emissions and stop global warming?' since s ....Supramolecular assembly in photovoltaic electrode design: Studies of ordered porphyrin/acceptor complexes on polythiophene electrodes. This research outlines an improved way to develop dye-sensitised photovoltaic solar cells for the conversion of sunlight into electricity, by increasing the molecular order of the cell components using host, guest interrelationships. As such, it addresses a problem of international concern 'How to reduce greenhouse gas emissions and stop global warming?' since solar cells do not produce carbon dioxide. To achieve our goals we draw on the skills of a team of experts from Australia (synthetic organic chemists), New Zealand (polymer and surface chemists) and Italy (photochemist and photophysicist). Such research is very appropriate for regional Australia, especially Central Queensland.Read moreRead less
Environmentally sustainable asymmetric synthesis: design and development of chiral hydrogen bonding organocatalysts. There is a pressing need for more environmentally sustainable and economically viable methods for asymmetric synthesis. This project aims to design, synthesise and evaluate new organocatalysts based on the principle of hydrogen bonding activation, a common feature of Nature's catalysts, enzymes.

There is a pressing need for more environmentally sustainable and economically viable methods for asymmetric synthesis. This project aims to design, synthesise and evaluate new organocatalysts based on the principle of hydrogen bonding activation, a common feature of Nature's catalysts, enzymes. These inexpensive, non-toxic, air- and moisture-stable catalysts may prove to be more efficient, selective and have broader applicability than catalysts based on transition metals. The growing Australian pharmaceutical and biotechnology industries will benefit from the development of these new Advanced Materials and the training provided to young scientists in the sought-after fields of asymmetric synthesis and catalysis.Read moreRead less

Catalytic Conversion of Waste Plastics to Hydrocarbon Fuels. This project aims to investigate the catalytic conversion of waste plastics to liquid fuels. Plastics comprise about 20% of municipal waste by volume, and are a major environmental concern as the present practice of disposal by landfilling has long-term hazard potential and is unsustainable. We propose to study the kinetics of the catalytic degradation of pure component plastics as well as their mixtures in a laboratory screw extrusi ....Catalytic Conversion of Waste Plastics to Hydrocarbon Fuels. This project aims to investigate the catalytic conversion of waste plastics to liquid fuels. Plastics comprise about 20% of municipal waste by volume, and are a major environmental concern as the present practice of disposal by landfilling has long-term hazard potential and is unsustainable. We propose to study the kinetics of the catalytic degradation of pure component plastics as well as their mixtures in a laboratory screw extrusion reactor, compare alternative catalysts, and develop process models to be used for scale up. The process and know-how developed will contribute to sustainable development, and provide an internationally competitive advantage to Australia.Read moreRead less

Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons.

This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the present project we shall develop suitable numerical techniques for solving the fractional order diffusion model, and apply these to the interpretation of experimental kinetic data. The outcome will be an improved model of adsorption dynamics considering the fractal nature of the solid.Read moreRead less
