Analysis and design of control systems with saturation and time-delay. Control engineering is an enabling technology without which most modern engineering systems, such as aircrafts or Internet, can not operate properly. Actuator saturation and time-delays are undesirable phenomena that often arise in control systems leading to poor performance and sometimes instability. For example, both of these phenomena arise in control of modern telecommunication systems, such as Active Queue Management in ....Analysis and design of control systems with saturation and time-delay. Control engineering is an enabling technology without which most modern engineering systems, such as aircrafts or Internet, can not operate properly. Actuator saturation and time-delays are undesirable phenomena that often arise in control systems leading to poor performance and sometimes instability. For example, both of these phenomena arise in control of modern telecommunication systems, such as Active Queue Management in TCP networks. The project aims at tackling these phenomena by using recently developed techniques in antiwindup for saturating actuators and by revisiting some classical methods for Smith predictor design for time-delayed systems.Read moreRead less
Large Scale Complex Multiagent Systems : Control Methodologies and Information Architectures. Future military operations are likely to involve increasing use of unmanned vehicles, airborne, underwater or on land. In some cases there will be very large formations. This research will develop methodologies which allow formations of unmanned vehicles to be configured. Much of the same methodology is applicable to the construction and operation of large scale sensor networks, identified by some comm ....Large Scale Complex Multiagent Systems : Control Methodologies and Information Architectures. Future military operations are likely to involve increasing use of unmanned vehicles, airborne, underwater or on land. In some cases there will be very large formations. This research will develop methodologies which allow formations of unmanned vehicles to be configured. Much of the same methodology is applicable to the construction and operation of large scale sensor networks, identified by some commentators as one of the most important technologies of the 21st century. They comprise large numbers of low cost networked sensors and will increasingly find application in security, agricultural and environmental monitoring.Read moreRead less

Neurobiological computation using self organization. Despite their phenomenal power and speed there are many simple things that computers still cannot do, that humans, and indeed many animals, are able to perform effortlessly. The research outlined in this proposal aims to develop new, biologically inspired, computational approaches that attempt to bridge this gap. This research will help place Australia, despite its relatively small size, as a leading research community in the development of ....Neurobiological computation using self organization.

The research outlined in this proposal aims to develop new, biologically inspired, computational approaches that attempt to bridge this gap. This research will help place Australia, despite its relatively small size, as a leading research community in the development of the next wave of computing devices. The development of new and "more natural" approaches to computing will deliver large dividends to a range of social, economic and environmental problems.Read moreRead less
Economical and practical design and analysis of probabilistic distributed systems. Complex computing systems composed of communicating processes are

distributed over networks, and interact with embedded hardware
components. They routinely operate in probabilistic environments:
hardware components fail randomly, but at known rates; and tactical
randomisation resolves competition for resources. Effective
specification, development and analysis methods for these systems
is crucial, and probability makes that particularly difficult.
The focus of this project is to develop new formal methods that are
economical and practical in use. Exploiting our recent advances in
probabilistic program semantics, we will add probability in a new
way to proven techniques in concurrency theory, including
refinement and hierarchical design.Read moreRead less
Algebraic reasoning for serialisability in probabilistic transaction systems. The ability to analyse complex systems is a vital part of the development of large-scale computer applications; a method that improves the quality of the analysis task would increase the competitiveness of the software industry, would attract future development work (in complex and intelligent systems) to Australia, and could contribute to national security.

Automation is increasing explosively, and the cliche is no longer that there is a cpu chip in your washing machine, television or automobile. Nowadays they are potentially in our cash cards, passports and soon on every item in our shopping baskets. Australia is a leader in adopting and developing such technology.
Security and privacy, hard enough for PCs, thus concerns smaller, more numerous devices that we might not even realise we are using.
