Atomistic Mechanisms of Stress Relaxation in Amorphous Materials. Amorphous materials represent a major thrust in the search for new materials. Metallic glasses have very high strength and can be cast to much finer tolerances than regular (polycrystalline) metals. Ceramic glasses are finding increasing applications in data storage, photoelectronics and fibre optics. The greatest obstacle to the application of amorphous solids is their brittleness. The goal of this project is to use accurate comp ....Atomistic Mechanisms of Stress Relaxation in Amorphous Materials. Amorphous materials represent a major thrust in the search for new materials. Metallic glasses have very high strength and can be cast to much finer tolerances than regular (polycrystalline) metals. Ceramic glasses are finding increasing applications in data storage, photoelectronics and fibre optics. The greatest obstacle to the application of amorphous solids is their brittleness. The goal of this project is to use accurate computer simulations to provide detailed pictures of how atomic motions relax stress in very different types of glasses and, through this insight, explore ways of modifying the mechanical properties of these materials.Read moreRead less
Fluctuation Effects in Non-Crystallising Liquids. Understanding the behaviour of liquids colder than their freezing temperature is important in areas as diverse as metal alloy preparation, prevention of cell damage in plants and animals at low temperatures, extending the working temperature range of new high voltage automotive batteries and controlling drug delivery in pharmaceuticals. Advances in these areas would represent important new manufacturing opportunities in industries already establi ....Fluctuation Effects in Non-Crystallising Liquids. Understanding the behaviour of liquids colder than their freezing temperature is important in areas as diverse as metal alloy preparation, prevention of cell damage in plants and animals at low temperatures, extending the working temperature range of new high voltage automotive batteries and controlling drug delivery in pharmaceuticals. Advances in these areas would represent important new manufacturing opportunities in industries already established in Australia. In this project the fundamental physical chemistry of supercooled liquids is developed and applied to a number of these technological challenges.Read moreRead less
Improving explosive emulsions by understanding surfactant interactions. This project will design new surfactants that will lead to more cost effective, stable and reliable explosive emulsions. The pressure required to force dispersed phase droplets to coalesce will be measured both directly and by osmotic stress. These parameters have not previously been measured for an inverse emulsion system. The measurements made will be correlated to the structure of the stabilising surfactant enabling new a ....Improving explosive emulsions by understanding surfactant interactions.

Bubble Stabilization and Density Control in Self-Supporting Explosive Emulsions. The mining industry in Australia employs about 70,000 people and has a total sales and service income of about $55B. Most mining outputs are commodities and a reduction in cost is the primary method of increasing market share. DNAP is a major supplier of explosive services to mines that produce coal, iron ore and gold for export. The work in this project will lead to more efficient explosives emulsions and allow mi ....Bubble Stabilization and Density Control in Self-Supporting Explosive Emulsions. The mining industry in Australia employs about 70,000 people and has a total sales and service income of about $55B. Most mining outputs are commodities and a reduction in cost is the primary method of increasing market share. DNAP is a major supplier of explosive services to mines that produce coal, iron ore and gold for export. The work in this project will lead to more efficient explosives emulsions and allow mining tolower total cost per unit sold. Such improvements in mining efficiencies will have a direct impact of the selling price of the product. Increased export earnings and a greater number of people employed in the industry would be direct results of the successful completion of the work proposed.Read moreRead less

The project will develop new investment assessments based on subset time-series modeling. Innovative evolutionary kernel smoothing algorithms using semi-parametric approaches will be introduced. The project will make three important applications of this modeling in financial markets: a) benchmarking and evaluation of inflation-indexed bonds; b) evaluation of the performance of global diversified investment funds; and c) prediction to provide early warning of the emergence of destabilising deflation or inflation. These three applications will lead to improved risk management practices and investment performance. Recursive algorithms will provide new statistical methods to study investment asset price movements and market volatility.

The improvement of climate change investigations by developing and applying innovative evolutionary subset time series modelling using semi-parametric sparse-patterned approaches. With an estimated US$6.98 trillion loss indicated in the Stern review, severe climate change will make world climate conditions harsher and more likely include large natural climate disasters. The health of the Australian economy is critically dependent on decisions of environmental managers. However, most problems of ....The improvement of climate change investigations by developing and applying innovative evolutionary subset time series modelling using semi-parametric sparse-patterned approaches. With an estimated US$6.98 trillion loss indicated in the Stern review, severe climate change will make world climate conditions harsher and more likely include large natural climate disasters. The health of the Australian economy is critically dependent on decisions of environmental managers. However, most problems of complexity arising in climate change involve issues on which we do not possess a deep understanding. This project draws upon a set of inter-disciplinary concepts and models centred in neural networks that enable us to advance our understanding of complexity, leading to superior quantitative tools and models to allow for improved environmental decision-making.

The project findings will help Australian exporters and importers understand and manage energy and resource price risks more effectively. The investment community will benefit through selecting optimal asset allocations and enhancing value to investors. It will also benefit many other agencies, particularly in the service industries. It is not well recognised that in developed countries, including Australia, the financial service and related sectors account for more than 60 percent of economic activity and employment, so it is critical that more sophisticated statistical methods be established, and practical applications conducted, in order to advance the understanding of complexity management in the financial service and related sectors.Read moreRead less

With over $1 trillion of investors' monies in the hands of fund managers, the importance of efficient investment decisions across all industry sectors is self evident.

With over $1 trillion of investors' monies in the hands of fund managers, the importance of efficient investment decisions across all industry sectors is self evident. Even if the modest target of systematically improving decision making by 1 or 2 % is set, the aggregate economic benefit achieved, given the compounding effects will be enormous. Any developed or developing country will profit from such advanced decision-making approaches. Therefore it is critical that more sophisticated statistical methods be established, and practical applications conducted, in order to advance the understanding of complexity management in the financial investment and other relevant sectors.Read moreRead less

The laser sources generally do not have simple (Gaussian) distributions. The applicant has recently developed a model, describing free propagation of complex (non-Gaussian) laser beams. This project seeks to develop a comprehending model for laser beams propagation through complex optical systems. The effects of various optical elements will be defined employing a novel method known as SAFE (Stable Aggregate of Flexible Elements) which is a compromise between geometrical and physical optics. Applying this model to micromachining and optical data storage (ODS), which need high beam quality (low divergence and good focussibility), enable accurate predictive capability critical to the optimisation of micromachining and ODS designs.Read moreRead less
