Construction of near optimal oscillatory regimes in singularly perturbed control systems via solutions of Hamilton-Jacobi-Bellman inequalities. Problems of optimal control of systems evolving in multiple time scales arise in a great variety of applications (from diet to environmental modelling). This project addresses the challenge of analytically and numerically constructing rapidly oscillating controls that would 'near optimally coordinate' the slow and fast dynamics.
Decomposition and Duality: New Approaches to Integer and Stochastic Integer Programming. Because of their rich modelling capabilities, integer programs are widely used in industry for decision making and planning. However their solution algorithms do not have the maturity of their cousins in convex optimisation, where the theory of strong duality is ubiquitous. Efficient methods for convex optimisation under uncertainty do not apply to the integer case, which is highly non-convex. Furthermore, i ....Decomposition and Duality: New Approaches to Integer and Stochastic Integer Programming. Because of their rich modelling capabilities, integer programs are widely used in industry for decision making and planning. However their solution algorithms do not have the maturity of their cousins in convex optimisation, where the theory of strong duality is ubiquitous. Efficient methods for convex optimisation under uncertainty do not apply to the integer case, which is highly non-convex. Furthermore, integer models usually assume the data is known with certainty, which is often not the case in the real world. This project will develop new theory and algorithms to enhance the analysis of integer models, including those that incorporating uncertainty, while also enabling the use of parallel computing paradigms.

Improving Choice Models: Multiple Goal Pursuit and Multi-Stage Decision Processes. This project aims to develop new econometric models of choice behaviour that recognise individuals adopt “how to decide” strategies when choosing between alternatives. Existing models simplistically assume that people evaluate all goods and choose the best of them, when in fact they ignore some goods, select what information is relevant, pursue multiple goals, and otherwise deviate from the assumptions commonly ma ....Improving Choice Models: Multiple Goal Pursuit and Multi-Stage Decision Processes. This project aims to develop new econometric models of choice behaviour that recognise individuals adopt “how to decide” strategies when choosing between alternatives. Existing models simplistically assume that people evaluate all goods and choose the best of them, when in fact they ignore some goods, select what information is relevant, pursue multiple goals, and otherwise deviate from the assumptions commonly made in econometric models. Filling in this significant gap in the choice modelling literature constitutes a significant contribution to improving our understanding of human decision making and policy analysis in every area of human endeavour.Read moreRead less
Accounting for preference seperability in stated choice experiments. This project aims to unite three separate streams of applied economic research into a single framework in order to develop a micro-economically consistent framework for demand forecasting and analysis. Forecasting demand to improve product performance or policy impacts requires realistic representations of how humans actually make choices. Combining theories of preference separability with recent developments in both activity a ....Accounting for preference seperability in stated choice experiments. This project aims to unite three separate streams of applied economic research into a single framework in order to develop a micro-economically consistent framework for demand forecasting and analysis. Forecasting demand to improve product performance or policy impacts requires realistic representations of how humans actually make choices. Combining theories of preference separability with recent developments in both activity and time use modelling and stated choice techniques, the project plans to develop new insights into consumer equilibrium as well as new econometric methods to test for the assumption of preference separability. Project outcomes would lead to an improved understanding of consumer behaviour as well as demand forecasting, with benefits to studies involving the need for benefit cost comparisons.Read moreRead less
Optimal electromaterial structures for energy applications. This project aims to develop new mathematical and modelling approaches to determine optimal configurations and parameters for material structures created from three-dimensional printing of combined metals and electromaterials. Electromaterials are needed for sustainable energy, but solving coupled-systems of highly nonlinear governing equations is needed for optimal control of spatial arrangement and composition in nano and micro-struct ....Optimal electromaterial structures for energy applications. This project aims to develop new mathematical and modelling approaches to determine optimal configurations and parameters for material structures created from three-dimensional printing of combined metals and electromaterials. Electromaterials are needed for sustainable energy, but solving coupled-systems of highly nonlinear governing equations is needed for optimal control of spatial arrangement and composition in nano and micro-structural domains. Dealing with this mathematical complexity is critical to developing high efficiency energy generation and gas storage systems. This is expected to enhance transport mechanisms within electrochemical devices and create opportunities for industry to use electrofunctional materials.Read moreRead less

Test bed for wide-area software defined networking research: This project aims to develop a wide-area test bed, spanning ten organisations, for conducting research and experimentation in the emerging disruptive technology of Software Defined Networking (SDN). SDN is likely to bring long-term transformation to the networking industry, much like cloud computing did, by enabling dynamic virtualised elastic network services under software control. The test bed will empower Australian researchers in network technologies and dependent applications (for example, multimedia and security) to collaboratively develop and demonstrate novel ideas at scale. This is expected to benefit Australia by giving our researchers international recognition in this nascent area, and developing a national talent pool for local industry.Read moreRead less
Interacting with visualisations of extremely large graph structures on large displays. The latest technological progressions have delivered very large data sets that can be modelled as graphs or networks. Examples include: social networks, biological data, and software structures. This project will develop techniques to allow users to visualise the graphs in the entirety and directly interact with data.
Transitioning to a water-secure future in the Basin. Increased water scarcity threatens the viability of the Murray-Darling Basin. There has been little analysis conducted of the consequences of water market impediments. The economic dimensions of trade impediments, water management, water market intervention and the net social benefits of water markets are at the core of this project. In particular, this project aims to explore: the impact of impediments and policy in water markets; how further ....Transitioning to a water-secure future in the Basin. Increased water scarcity threatens the viability of the Murray-Darling Basin. There has been little analysis conducted of the consequences of water market impediments. The economic dimensions of trade impediments, water management, water market intervention and the net social benefits of water markets are at the core of this project. In particular, this project aims to explore: the impact of impediments and policy in water markets; how further water market products may increase water market efficiency; and, the nature and sources of transactions costs in markets. Benefits from this project will enhance resilience and adaptation of irrigators to future climate change and water shortages, as well as providing future policy guidance.Read moreRead less
