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 probab ....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.

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.
The results of this project will have a direct influence on currently available design tools; the fact that Australian institutions will be responsible for key theoretical results in this growing field will strengthen Australia's position worldwide as an international centre for computer science.Read moreRead less
Hidden-state modelling for modular analysis of information flow, protection and risk evaluation. 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.

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.
Our research aims to make it easier and more effective to describe and then successfully build-in features that enforce security without adverse impact on usability.Read moreRead less

Refinement of Temporal and Epistemic Specifications in Asynchronous Systems. Designing distributed systems is a complex activity requiring rigorous mathematical models of designs and specifications. It is desirable for the mathematical notations to be as close as possible to intuitive notions used by designers.

Designing distributed systems is a complex activity requiring rigorous mathematical models of designs and specifications. It is desirable for the mathematical notations to be as close as possible to intuitive notions used by designers. One such notion is the idea that components in a distributed system have states of knowledge. Previous work has developed a calculus enabling derivation of systems with global clock by series of correctness-preserving transformations from a knowledge-based specification. This project will generalize this work to a calculus for systems that lack a global clock, and implement a tool providing automated support for use of the calculus.Read moreRead less

The aim of the project is to contribute to bridge the gap between learning and logic, theoretically and practically. Our purpose is to extend considerably the scope of the declarative programming paradigm, and build a system that can be used to solve learning or discovery problems as encountered in Artificial Intelligence. The system will enable rapid prototyping when applied to problems involving deduction, induction, and nonmonotonic reasoning. We intend the system to become a standard tool for tackling a broad range of applications, and the underlying theory to provide new insights on the logical foundations of Artificial Intelligence.
