An innovative structural system utilising sandwich panel technology and shell action has recently emerged. These aesthetically pleasing curved structures are durable and spacious with fast construction time. They have residential and commercial applications and have attracted considerable local and overseas interest. There are no definitive procedures for their analysis and design and their behaviour is complex involving many variables such as sandwich layer interaction, shape, openings, structural action, etc. This project will generate fundamental knowledge on their behaviour over a range of properties and operating conditions and develop guidelines to ensure safe and economical design, bringing economic benefits to Australia.Read moreRead less
Assessing the full impacts of high efficiency heavy vehicles in urban traffic networks using new analytical tools. Significant economic benefits result from new innovative heavy vehicles, which are able to carry up to twice the payload of standard semi-trailers. In addition, those vehicles have the potential to reduce overall accidents and evironmental degradation. Those benefits need to be traded-off against the impacts on other road users. This research will improve the operation of such ve ....Assessing the full impacts of high efficiency heavy vehicles in urban traffic networks using new analytical tools. Significant economic benefits result from new innovative heavy vehicles, which are able to carry up to twice the payload of standard semi-trailers. In addition, those vehicles have the potential to reduce overall accidents and evironmental degradation. Those benefits need to be traded-off against the impacts on other road users. This research will improve the operation of such vehicles in regional centres by producing: (1) an assessment methodology to deal with options for network efficiency gains which will capture the full impacts; and (2) a computer modelling tool based on fundamental research to quantify those impacts, in terms of delays and accident rates.Read moreRead less
Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less
Application of Water Based Fractionation in the Assessment of Metallurgical Coal. The metallurgical coal market (13% of coal market) is highly specialized, and competitive. The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities.

The coal, which is utilized as a reducing agent in iron making, represents more than 52% of Australian coal exports. This study addresses growing evidence that organic liquids used to fractionate and in turn assess metallurgical coals lead to negative assessments, hence loss of markets, and lost opportunities. A new water based fractionation method will be established, and a systematic investigation into the effects of the organic liquids will be undertaken. These results will be used to build a case for replacing the organic liquids used in the industry, which are known to have negative health and environmental impacts. Read moreRead less

Open pit mine design and production scheduling (OPDPS) deals with the management of cash flows in the order of hundreds of millions of dollars, and is a critical aspect of mining ventures. To enhance decision-making under conditions of uncertainty, this proposal aims to develop a new methodology for OPDPS based on mathematical and statistical techniques which model uncertainty in key parameters, geological, mining and market/cost and their effects on economic forecasts. The new formulation is founded on stochastic integer programming, and its integration with spatial stochastic simulations of geological attributes. Methods developed are computerised and tested in field studies.Read moreRead less

Stochastic short-term production scheduling (STPS) in open pit mines provides a new framework allowing production schedules to manage risk robustly despite uncertainties in geological and mining conditions. STPS depends on both mining (stockpiling process, multiple ore types and processors, waste production, equipment mobility, feasible sequencing) and geological (in-situ ore variability, geological uncertainty, simulated 'future' grade control data) factors.
