Topological Optimization of Load-carrying Structural Systems with Repetitive Geometrical Patterns. Periodic structures are increasingly used in the design of the structural systems or sub-systems of buildings, bridges, aircraft, motor vehicles etc. The duplication of identical or similar modules significantly reduces the production cost and greatly simplifies the assembly process. In many cases periodic structures are also selected for their distinctive aesthetic appeal. The proposed research wi ....Topological Optimization of Load-carrying Structural Systems with Repetitive Geometrical Patterns. Periodic structures are increasingly used in the design of the structural systems or sub-systems of buildings, bridges, aircraft, motor vehicles etc. The duplication of identical or similar modules significantly reduces the production cost and greatly simplifies the assembly process. In many cases periodic structures are also selected for their distinctive aesthetic appeal. The proposed research will develop advanced techniques for the optimal design of such structures. The new design tool will enable Australian engineers and architects to create innovative and efficient structural systems for a wide range of applications and to become involved in high profile international projects.

There is a widespread need throughout the Australian transport, defence and construction industries for high performance energy absorption devices. Data from the Australian Transport Safety Bureau show that in 2002 there were 1,715 people killed in 1,525 crashes in Australia. The proposed research will develop advanced techniques for improving crashworthiness of vehicles, roadside barriers and other energy absorption devices. This will lead to significant reductions in injury to people and damage to structures caused by impact; and thus substantial savings for the nation from the enormous costs associated with the fatalities, injuries and structural damages.

Design surface feature recognition for near net shaped manufactured components. The aim of this project is to investigate methods and techniques that, given an ab initio design requirement, allow databases of knowledge from previous designs to be intelligently searched for similar patterns, both geometric and physical state, that will assess the likelihood of a successful design and suggest potential alternatives based on previous experience

The aim of this project is to investigate methods and techniques that, given an ab initio design requirement, allow databases of knowledge from previous designs to be intelligently searched for similar patterns, both geometric and physical state, that will assess the likelihood of a successful design and suggest potential alternatives based on previous experience
The plan is to approach the research problem from a machine learning/pattern recognition point of view. By mapping the characterized properties into a search space of reduced dimensionality in which feature patterns have been pre-classified through supervised training, it should be possible to identify similar features.

The large and growing demand for replacement tissues and organs has spurred rapid growth in the emerging field of tissue engineering, which aims to form new tissues in the laboratory by combining living cells and synthetic scaffolds. A major challenge lies in the production of thick tissues, which require a blood supply in order to survive. Uniquely, this project aims to grow in the laboratory a vascular system based on natural structures, which can then be used to support new tissue growth. Australia is well placed to reap the rewards of this work, having a track record in commercialisation of medical technologies, resulting in an improved quality of life for many Australians and substantial direct and indirect economic benefits.Read moreRead less
