We explore various definitions and characteristics of emergence, how we might recognise and measure emergence, and how we might engineer emergent systems. We discuss the TUNA (Theory Underpinning Nanotech Assemblers) project, which is investigating emergent engineering in the context of molecular nanotechnology, and use the TUNA case study to explore an(More)
We consider models of emergence, adding downward causa-tion to conventional models where causation permeates from low-level elements to high-level behaviour. We describe an architecture and prototype simulation medium for tagging and modelling emergent features in CA-like systems. This is part of ongoing work on engineering emergence.
We propose a framework for engineering emergent behaviour that allows system specification and design at the level of the emergence. We discuss how rule migration can be used to translate this high-level multi-layer design (mobile process model) into an equivalent simple cellular automaton model with only local rules, and emergent behaviour. In this paper,(More)

To reflect on the role of risk-taking and risky play in child development and consider recommendations for the injury prevention field, a symposium was held prior to the November 2013 Canadian Injury Prevention and Safety Promotion Conference. Delegates heard from Canadian and international researchers, practitioners and play safety experts on child(More)
Prospective authors will find detailed and up-to-date submission instructions on the Journal's homepage. This issue of the R Journal comes on the heels of R 2.10.1. R 2.10 sports a variety of changes to • the documentation system • factor handling • debugging and code analysis support • encodings management • [[ semantics • regular expression processing •(More)
Prospective authors will find detailed and up-to-date submission instructions on the Journal's homepage. This issue comes approximately one month after CRAN passed a new milestone: the number of packages in the repository had reached 3000. With such a large number of packages (and the number is still rising of course) it becomes increasingly difficult for(More)
This thesis describes a framework for designing emergent behaviour. The framework is comprised of a simulation architecture, a rule migration process, and a rule combination language. Desired emergent behaviour is specified using a multi-level model which describes the behaviour at the appropriate level in the emergence hierarchy, using downward causation(More)
