This project aims to resolve the complex interactions affecting the long-term performance of geosynthetic liner systems under harsh environmental conditions for preventing groundwater contamination. Failures of waste containment lining systems result in millions of dollars remedial costs and high societal costs. The project expects to underpin the development of an experimentally-validated theory to predict the performance of geosynthetic liner systems at high temperatures. Expected outcomes of the project are the establishment of a new conceptual framework and providing new guidelines for the design of geosynthetic liner systems for environmental protection. These outcomes are expected to benefit the waste and mining industries by informing planning, decision makers, consultants and construction engineers with science-based information on new lining systems for landfills and mining and industry waste containment.Read moreRead less
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.

Characterising and suppressing vortex induced vibration. Vortex-Induced Vibration has become the design limiting factor in offshore design of elements such as the flexible pipelines that bring oil and gas to the surface. With rising oil and gas prices it is becoming more economic to explore such resources in deeper waters, which exacerbates the problem. Currently, high factors of safety must be used in the design of such pipelines because of our current lack of understanding of when the vibratio ....Characterising and suppressing vortex induced vibration. Vortex-Induced Vibration has become the design limiting factor in offshore design of elements such as the flexible pipelines that bring oil and gas to the surface. With rising oil and gas prices it is becoming more economic to explore such resources in deeper waters, which exacerbates the problem. Currently, high factors of safety must be used in the design of such pipelines because of our current lack of understanding of when the vibrations occur and their frequency and amplitude. This study will provide insight into the character of such vibrations and also look at means of suppressing them.Read moreRead less

Complex dynamical behaviour is inherent to many real-world systems including telecommunications networks, financial markets and biological systems. High performance signal processing and control algorithms for such large-scale, complex systems are computationally very expensive in general. An important class of large-scale Markovian models arising in many applications shows a remarkable hierarchical property, displaying strong interactions within certain clusters of states and weak interactions among these clusters. By utilizing this property, the proposed project will design and analyze novel reduced-complexity signal processing and control algorithms with rigorous performance guarantees. In addition, this project will explore possibilities of making these algorithms hierarchical such that they are easy to implement through decentralization.Read moreRead less
