Measurement and comparison of individual external doses of high-school students living in Japan, France, Poland and Belarus -- the "D-shuttle" project --
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four
in France, eight in Poland and two in Belarus cooperated in the measurement and
comparison of individual external doses in 2014. In total 216 high-school
students and teachers participated in the study. Each participant wore an
electronic personal dosimeter "D-shuttle" for two weeks, and kept a journal of
his/her whereabouts and activities. The distributions of annual external doses
estimated for each region overlap with each other, demonstrating that the
personal external individual doses in locations where residence is currently
allowed in Fukushima Prefecture and in Belarus are well within the range of
estimated annual doses due to the background radiation level of other
regions/countries
A Formal Modelling Framework for Developing Multi-agent Systems with Dynamic Structure and Behaviour
Multi-agent systems exhibit highly dynamic behaviour within dynamic environments. Modelling of individual agents within such systems demands considering both evolving data structures and the control over their internal changing states. In addition, modelling of the overall system implies modelling of the agents ’ configuration, including their ability to exchange messages as well as the ability to re-structure their formation over time. This paper presents a formal modelling framework based on Communicating X-machines, allowing the specification of multi-agent software systems with a dynamic structure and behaviour. A case study illustrates the proposed modelling approach
