The Australian Centre for Complex Systems brings together leading researchers from several disciplines and institutions to conduct research on questions fundamental to understanding and managing complex systems. Its core research program, based on the theme of computation in and by networks of agents, has two interwoven strands. The science strand addresses questions about emergent properties, natural computation, and nonlinear dynamics. The engineering strand addresses issues about methodology, modelling toolkits, and management and control. Practical applications are advanced via collaborative projects that address key issues in biology, environment, and socio-economics.Read moreRead less
A Compositional Model for Verifying and Programming Ecologies of Smart Internet Devices. Emerging in 21st century computing is what we perceive as device ecologies, or collections of devices that can exhibit smart behaviour, automate tasks, interact synergistically with one another, with users and Internet resources, and provide aid and value in daily life and work. Device ecologies will be seen in areas as diverse as e-commerce, health care, home automation, office automation, manufacturing, an ....A Compositional Model for Verifying and Programming Ecologies of Smart Internet Devices. Emerging in 21st century computing is what we perceive as device ecologies, or collections of devices that can exhibit smart behaviour, automate tasks, interact synergistically with one another, with users and Internet resources, and provide aid and value in daily life and work. Device ecologies will be seen in areas as diverse as e-commerce, health care, home automation, office automation, manufacturing, and defense. This project will develop a novel model and language for analyzing and programming device ecologies. This will be an Australian contribution towards techniques for constructing advanced applications that work over the computing infrastructure of the future.Read moreRead less
More information for better utility; less information for better privacy. More information for better utility; less information for better privacy. The contradiction is everywhere in contemporary IT: doctors need accurate information for diagnosis, but insurance companies' access should be limited; on-line retailers use your postcode to present interesting products, but they also deduce from it how much you will pay. One way to manage this contradiction is to tolerate "small" information flows p ....More information for better utility; less information for better privacy. More information for better utility; less information for better privacy. The contradiction is everywhere in contemporary IT: doctors need accurate information for diagnosis, but insurance companies' access should be limited; on-line retailers use your postcode to present interesting products, but they also deduce from it how much you will pay. One way to manage this contradiction is to tolerate "small" information flows providing the risks involved can be accurately gauged. This project will build on recent advances in information measuring to develop new techniques for measuring the extent to which computer systems can defend against threats to privacy. Success in this project will lead to completely novel methods for security analysis of on-line applications where privacy is a critical issue.Read moreRead less
