background although there is a general agreement on the benefits of evidence informed health policy development given resource constraints especially in low-income countries (lics), the definition of what evidence is, and what evidence is suitable to guide decision-making is still unclear. our study is contributing to filling this knowledge gap. we aimed to explore health policy actors’ views r...

This paper presents a newly developed implementation of remote message passing, remote actor creation and actor migration in SALSA Lite. The new runtime and protocols are implemented using SALSA Lite’s lightweight actors and asynchronous message passing, and provide significant performance improvements over SALSA version 1.1.5. Actors in SALSA Lite can now be local, the default lightweight acto...

The long-term objective of our research is the visualization of the simulation of the behavior of realistic human beings, called synthetic actors, in a given environment, interactively decided by the animator. The ultimate reason for developing realistic-looking synthetic actors is to be able to use them in virtually any scene that recreates the real world. However, a virtual scene-beautiful th...

By looking at two recent and widely recognized productions of Henry Purcell’s Dido and Aeneas (by choreographer Sasha Waltz, Berlin 2005, and theatre-director Sebastian Nübling, Basel 2006) this article discusses three main aspects: 1. Genre: Coming from a Tanztheater (Waltz) and a Sprechtheater (Nübling) background, both directors renegotiate conventions of the operatic genre, and consciously ...

This technical note uses the Ptolemy II interface automaton editor to compose networks of dataflow actors and buffers. The automata are first described as Actif actors; the composition of the automata together with a controller automata reveals the combined behavior of the network. This technical note can be referenced as: “Interface Automata and Actif Actors,” H John Reekie, UC Berkeley, Novem...

RePast is a well-known agent-based toolkit for modelling and simulation of complex systems. The toolkit is normally used on a single workstation, where modelling, execution and visualization aspects are dealt with. This paper describes an approach aimed to distributing RePast models, with minimal changes, over a networked context so as to address very large and reconfigurable models whose compu...

Planning is a field of interest in many scientific disciplines. These scientific areas cover a multitude of planning approaches that at first sight do not have much in common: psychophysiological analyses, organizational science, linguistics, cognitive science, operations research, and spatial science, to name just a view. The differences in ontologies and methods used make it difficult to make...

This paper proposes a novel approach –SARTto the development of real-time systems which is based on super actors, i.e., actors whose behaviour is modelled by statecharts. SART borrows structural concepts from known methods for reactive systems like ROOM and UML-RT, and favours ease of construction by making actors reusable and composable software components. The distinguishing factors of SART a...
