Accurate Context-Aware Search for Managed Document Collections. Search is a key component of a vast range of computing applications. However, while search on large collections of general-purpose text is well-understood, and the best systems are highly effective, search on smaller or special-purpose collections is much less reliable and has attracted relatively little research. By identifying general ways of using context such as user history or prior page usefulness, the quality of search in s ....Accurate Context-Aware Search for Managed Document Collections. Search is a key component of a vast range of computing applications. However, while search on large collections of general-purpose text is well-understood, and the best systems are highly effective, search on smaller or special-purpose collections is much less reliable and has attracted relatively little research. By identifying general ways of using context such as user history or prior page usefulness, the quality of search in such cases can be greatly improved. Products that make use of these principles will provide greater workplace efficiency and be able to locate information that other search tools cannot identify.Read moreRead less

Perovskite-based electrocatalysts for water electrolysis. This project aims to develop novel perovskite-based catalysts with high catalytic activity and long-term stability for the practical application of alkaline water splitting. A new family of overall water-splitting materials in alkaline media based on low-cost and earth-abundant perovskite oxides will be developed, which offer a viable alternative to the benchmark noble metal-based catalysts. Clean hydrogen energy generated by these effici ....Perovskite-based electrocatalysts for water electrolysis. This project aims to develop novel perovskite-based catalysts with high catalytic activity and long-term stability for the practical application of alkaline water splitting. A new family of overall water-splitting materials in alkaline media based on low-cost and earth-abundant perovskite oxides will be developed, which offer a viable alternative to the benchmark noble metal-based catalysts. Clean hydrogen energy generated by these efficient perovskite catalysts will not only reduce carbon dioxide emissions and alleviate air pollution, but also create opportunities for Australian industries, such as the widespread use of renewable solar and wind energy and fuel cell vehicles.Read moreRead less
Using Past Queries for Fast and Accurate Web Searching. Searching the entire Internet, or a company web site, has become a vital task for modern organisations.

Searching the entire Internet, or a company web site, has become a vital task for modern organisations. While there has been significant research into improving search engines through using web pages themselves, very little attention has been paid to improving web search by exploiting the vast numbers of queries that users submit to search engines each day. This project will use state of the art compression and algorithmic techniques to improve the speed and accuracy of web search using data gleaned from millions of Internet queries (provided under agreement by Microsoft). Improving search engines will have a direct benefit to many Australian industries, and support the government's priority area of "smart information use".Read moreRead less
Hydro-mechanical interactions in coal geo-sequestration of carbon dioxide. One of the most critical environmental issues facing society is that of global warming because of increasing concentrations of carbon dioxide released from burning of fossil fuels. Storage of CO2 in the ground, geo-sequestration, offers the promise of significant reductions in atmospheric CO2 release, particularly from coal fired power stations which produce 40% of Australia's CO2 emissions.

One of the most critical environmental issues facing society is that of global warming because of increasing concentrations of carbon dioxide released from burning of fossil fuels. Storage of CO2 in the ground, geo-sequestration, offers the promise of significant reductions in atmospheric CO2 release, particularly from coal fired power stations which produce 40% of Australia's CO2 emissions. The proposed project will lead to greater understanding and reduced risks during the injection and storage of CO2 in deep unmineable coal deposits. This will contribute to national efforts to reduce global warming, safeguard the Australian coal industry, and allow continued electricity generation from coal-fired plants. Read moreRead less
