COMPLEX NETWORKS: DYNAMICS, OPTIMIZATION AND CONTROL. Complex networks such large power grids, the Internet, transportation networks and co-operation networks of all kinds provide challenges for frontier technologies particularly computing, communication and control. In particular, advanced societies have become dependent on large infrastructure networks to an extent beyond our capability to plan and control them.

Complex networks such large power grids, the Internet, transportation networks and co-operation networks of all kinds provide challenges for frontier technologies particularly computing, communication and control. In particular, advanced societies have become dependent on large infrastructure networks to an extent beyond our capability to plan and control them. The recent spate of collapses in power grids and virus attacks on the Internet illustrate the need for research on modelling, analysis of behaviour, planning and control in such networks. This project aims to establish research in this area for Australia's benefit.Read moreRead less
Precision Pulsar Timing and its Applications. The rapidly rotating pulsars known as millisecond pulsars have period stabilities which rival that of the best terrestrial clocks. Observations of many millisecond pulsars spread across the sky should allow detection of the gravitational-wave background - likely to be the first direct detection of gravity waves. It will also enable establishment of a long-term time standard which is independent of and probably superior to that derived from terrestria ....Precision Pulsar Timing and its Applications.

Observations of many millisecond pulsars spread across the sky should allow detection of the gravitational-wave background - likely to be the first direct detection of gravity waves. It will also enable establishment of a long-term time standard which is independent of and probably superior to that derived from terrestrial clocks. New analysis techniques and establishment of an international observing network will be required. Investigation and application of techniques for overcoming radio interference will be an important part of the project.Read moreRead less
A clearer view of the evolving universe. The two complementary research objectives of this proposal are (i) a basic research program to understand star formation in galaxies through a study of the correlation betwen far infrared and radio continuum emission and (ii) a strategic research program to develop interference mitigation techniques to enable the next generation of radio telescopes which will study star formation in the early Universe.

This programme of research innovation in radio astronomy will also promote the broad aims of furthering opportunities for Australian participation in international science and of gaining insight into ways in which Australia can exploit its niche advantages in the global economy.Read moreRead less
Exploring the last frontier: cosmic reionization and the first galaxies. This program will help to position Australia as a leader in the development of the Square Kilometre Array, a 1.5 billion Euro radio telescope that Australia is vying to host. The program takes advantage of the uniquely radio quiet environment of Western Australia to achieve unprecedented measurements of the 'first light fossils' in the Universe, which reside in the portion of the radio spectrum that is filled by FM radio tr ....Exploring the last frontier: cosmic reionization and the first galaxies. This program will help to position Australia as a leader in the development of the Square Kilometre Array, a 1.5 billion Euro radio telescope that Australia is vying to host. The program takes advantage of the uniquely radio quiet environment of Western Australia to achieve unprecedented measurements of the 'first light fossils' in the Universe, which reside in the portion of the radio spectrum that is filled by FM radio transmissions in most parts of the planet. This ground-breaking research program will provide training for the next generation of world-class scientists and add to the already high profile of Australian astrophysics.Read moreRead less
Understanding the Evolution of the Universe. It is our belief that this research's most valuable use is serving as a catalyst to engage young minds towards science and technology. The research proposed here is intended to capture the imagination of potential young scientists and technologists and ultimately should lead Australians to undertake studies in these areas.

The research proposed here is intended to capture the imagination of potential young scientists and technologists and ultimately should lead Australians to undertake studies in these areas. In addition there are more direct economic benefits. This program will train a number of young scientists in problem solving, computer programming, and image processing; skills which can equally be applied within industry and science.

Differential geometry is a major branch of mathematics studying shape by using calculus and differential equations. This is a fundamental research project in this area, especially concerned with the interaction between geometry, differential equations, and symmetry. The mathematical notion of symmetry was already formalised early last century and nowadays lies at the very heart of mathematics and physics. Advances in this area provide essential tools in basic science and unexpected technological benefits can easily arise (for example, in medical imaging). Fundamental mathematical research is absolutely necessary if Australia is to maintain a presence on the international scientific stage.Read moreRead less
Exploring the Frontiers of Feasible Computation. The project aims to delineate the boundary between feasible and infeasible computational problems. A problem is considered feasible if there is an algorithm to solve it in worst-case time bounded by a polynomial in the input size. This is probably impossible for the important class of NP-complete problems. However, typical examples of NP-complete problems can often be solved in polynomial time, because worst-case problems are rare. The project is ....Exploring the Frontiers of Feasible Computation. The project aims to delineate the boundary between feasible and infeasible computational problems. A problem is considered feasible if there is an algorithm to solve it in worst-case time bounded by a polynomial in the input size. This is probably impossible for the important class of NP-complete problems. However, typical examples of NP-complete problems can often be solved in polynomial time, because worst-case problems are rare. The project is relevant to public-key cryptography, where breaking an encryption scheme should be infeasible, and to many real-life situations where NP-complete problems need to be solved, either exactly or approximately.Read moreRead less
