Mathematical modelling of dye-sensitised titania solar cells: a route to improved efficiency in production. Dye-sensitised titania solar cells (DSCs) provide a technically and economically credible alternative to silicon photovotaic devices. Increasing the efficiency of commercially produced DSCs to 12% from the current production cell efficiency of 6%,will result in significantly lower delivered energy costs than the current alternative photovoltaic devices.

Dye-sensitised titania solar cells (DSCs) provide a technically and economically credible alternative to silicon photovotaic devices. Increasing the efficiency of commercially produced DSCs to 12% from the current production cell efficiency of 6%,will result in significantly lower delivered energy costs than the current alternative photovoltaic devices. This project will develop a mathematical model of a DSC as a first stage in the development of a decision support capability for the manufacture of more efficient DSC's. The model will extend existing models to incorporate full transport modelling and side-reactions in the electrolyte and will be validated by experimental work.Read moreRead less

This study will also incorporate an econometric analysis of the potential for specific aluminium MIM parts. Using this novel, multidisciplinary approach, the market definition and the technology development will occur concurrently. The outcome will be an aluminium MIM system and a new business opportunity for a Queensland manufacturing company in a market that is growing at 10-25% per year and is expected to exceed $US1 billion in 2003.Read moreRead less
Financing aged care in Australia: Mitigating fiscal gaps and maintaining intergenerational equity. Aged care has been identified as a significant contributor to the growing fiscal problems predicted for Australian government finances during the next 10 to 20 years.

Aged care has been identified as a significant contributor to the growing fiscal problems predicted for Australian government finances during the next 10 to 20 years. This project will develop the cutting-edge modelling tools needed to allow Australia to make informed decisions about possible reforms in aged care financing. It will create significant national benefits by allowing detailed assessment of the distributional impact of a wide range of possible reforms, including how the outcomes of any policy change will affect disadvantaged sections of our society, whether different generations will be fairly treated, and the impact by gender.Read moreRead less
Novel statistical analysis for traffic modelling. This collaborative research with Queensland Main Roads aims to develop and apply novel statistical modelling techniques which improve on the current statistical methods used for transport modelling. The research outcomes will provide a high level of accuracy in terms of predictions for trips leading to better use of expensive survey data. Predictions will be incorporated into transport models.

This collaborative research with Queensland Main Roads aims to develop and apply novel statistical modelling techniques which improve on the current statistical methods used for transport modelling. The research outcomes will provide a high level of accuracy in terms of predictions for trips leading to better use of expensive survey data. Predictions will be incorporated into transport models. Such model will be used for improving decisions involving multi billion dollar transport infrastructure investment and applied to South East Queensland. The methods can be extended to transport models for other large conurbations in Australia. Outcomes include improved transport systems with economic benefits for business and the community.

Expenditure needs and drawdown of retirement savings during later life: how important are demographic factors and financial resources? Projections of expenditure patterns in retirement which allow for population heterogeneity will provide individuals with a better appreciation of their income needs and their savings requirements for a comfortable retirement.

Projections of expenditure patterns in retirement which allow for population heterogeneity will provide individuals with a better appreciation of their income needs and their savings requirements for a comfortable retirement. It will also enable financial institutions to develop products which better target retirees' needs over the course of retirement, and in addition it will enable improved assessment of aspects of Government income support policy. Specifically, understanding the complex interactions between private and public pensions, and concession card receipt upon expenditure behaviour, will enable more accurate costings of the public support of elderly families as Australia's population ages.

The project aims to develop computational models to predict emissions of nitric oxides and carbon monoxide from sugar-mill boilers burning bagasse. Bagasse combustion does not contribute to greenhouse gas emissions and clean and efficient combustion of this fuel has become very important for the sugar industry and for Australia. The project combines the opportunity of direct boiler measurements by SRI with the modelling expertise at the University to develop combustion-kinetics models for these species. The models will be incorporated into the previously developed computational fluid dynamics - combustion code of the furnace to give the capability of emission prediction as a function of burner operating conditions and fuel parameters.Read moreRead less
Investigating the Concordance and Transmission of International Business Cycles. Business cycle recessions are costly. Apart from the economic cost, there is the devastating social and psychological impact of unemployment on individuals and families. The 1990/91 recession cost Australia somewhere between $25 and $30 billion in lost output and resulted in a half a million additional unemployed. Australia will certainly experience another recession and, given its openness to international influenc ....Investigating the Concordance and Transmission of International Business Cycles. Business cycle recessions are costly. Apart from the economic cost, there is the devastating social and psychological impact of unemployment on individuals and families. The 1990/91 recession cost Australia somewhere between $25 and $30 billion in lost output and resulted in a half a million additional unemployed. Australia will certainly experience another recession and, given its openness to international influences, it is likely that it will originate elsewhere in the world. In delivering a greater understanding of the interdependencies in international business cycles, the project will assist economic policymakers in their efforts to ameliorate Australia's next recession.
