The provision of broadband services is a high priority for the Australian government as evidenced by the various initiatives around Australia. The merging of backbone infrastructures for access environment will overcome unnecessary cost of maintaining and upgrading two separate networks for wired and wireless applications. The merged infrastructure will potentially provide inexpensive and cost-effective solutions for truly broadband services with a choice of wired or wireless connectivity to customers and will remove the rural-urban broadband divide that has been challenging Australia. The outcomes of this project can lead to new business ventures and will further strengthen the telecommunication industry.Read moreRead less

Singular and Analytic Perturbations, Slow and Fast Time Scales in Control Theory and Viability Theory and their Applications. We propose an innovative approach to several important classes of mathematical problems, whose data depend analytically on small perturbation parameters. Time scale problems, and, in particular, the interaction of two types of evolution, slow and fast, arise in many scientific domains (biotechnology, physics, engineering, etc).We expect to develop new techniques for analy ....Singular and Analytic Perturbations, Slow and Fast Time Scales in Control Theory and Viability Theory and their Applications. We propose an innovative approach to several important classes of mathematical problems, whose data depend analytically on small perturbation parameters. Time scale problems, and, in particular, the interaction of two types of evolution, slow and fast, arise in many scientific domains (biotechnology, physics, engineering, etc).We expect to develop new techniques for analysis and asymptotic optimisation of singularly perturbed control systems and Markov decision processes. In particular, we plan to establish links between general nonlinear optimal control problems with time average criteria and linear programming problems in the space of limit occupational measures generated by the underlying control system.Read moreRead less
Multiscale Singularly Perturbed Control Systems. We propose to develop a unified averaging technique to analyse deterministic and stochastic multiscale singularly perturbed control systems. Such systems arise as mathematical models of real-world dynamical systems in which state variables can change their values with the rates of different orders of magnitude. The technique is based on the assumption that the system, which would describe the dynamics of the fast state variables if slow ones were ....Multiscale Singularly Perturbed Control Systems. We propose to develop a unified averaging technique to analyse deterministic and stochastic multiscale singularly perturbed control systems. Such systems arise as mathematical models of real-world dynamical systems in which state variables can change their values with the rates of different orders of magnitude. The technique is based on the assumption that the system, which would describe the dynamics of the fast state variables if slow ones were frozen, possesses certain ergodicity properties expressed in the existence of its limit occupational measures set. Conditions for the existence of such a set will be studied and its structure will be described.Read moreRead less

The R&D and commercialisation of the DWDM-lite will have a significant impact on the efficiency of Australia's telecommunications industry with consequent flow-on effects to the productivity and competitiveness of Australian telecommunications industry. The availability of broadband telecommunications services to regional communities at service and services levels to those of metropolitan customers is a recognised national priority. It lies at the core of the Australian Government's recently announced Connect Australia plan directing at regional community benefits in improved availability and affordability of broadband telecommunications services. The product will enhance Australian participation in the global equipment supply industryRead moreRead less
