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...

We present a study of the interaction properties of objects in concurrent object oriented programming. We identify a set of basic interaction mechanisms: object identity, asynchronous message passing, implicit receive primitive, which are closed to those of the actor model. Then, we define a minimal algebra of actors as a basic formalism for representing the semantics of concurrent object orien...

We present a logical formalism of the actor-based concurrent object oriented computation in terms of the deduction in linear logic. By encoding messages and objects in the actor model as formulae of linear logic, the distributed state of the actor computation, regarded as a connguration, can be represented as a multiset of object formulae and message formulae. Methods are encoded as a special f...

The prevalence of RESTful services requires that we pay closer attention to how the principles that underlay REST are realized in actual services being implemented. This is especially crucial as REST is being applied to problem domains that require complex operations such as transactions. In this paper we investigate the relationship between RESTful web services and the actor model of computati...
