This paper describes the usage patterns of the ThreadedComposite actor in Ptolemy II. This actor enables the execution of opaque actors (atomic actors or composite actors with directors) in a separate thread, thus providing multithreading for models of computation that are not already multthreaded. It can be used to execute an actor in the background, to execute multiple actors in parallel (e.g...

the caspian sea region, because of the proximity of two permanent powers - russia and iran- and the emergence of newly independent republics, is one of the most dynamic places in the world. in addition, the continuity of interests of other global actors, including the united states and europe, with the coastal countries has added to the complexity and dynamics. in this regard, the region energy...

Maternal mortality continues to claim the lives of thousands of women in Latin America despite the availability of effective treatments to avert maternal death. In the past, efforts to acknowledge cultural diversity in birth practices had not been clearly integrated into policy. However, in Otavalo (Ecuador) a local hospital pioneered the implementation of the 'Vertical Birth'-a practical manif...

The personality profiles and cognitive styles of 191 professional actors were compared to general population samples. Actors of both sexes were significantly higher than comparison groups in extraversion, openness to experience, and agreeableness. There was a trend towards higher neuroticism. The actors also scored significantly more highly than comparison groups on Baron-Cohen s empathizing qu...

The syntax and semantics of actors and-agents is rst deened separately, using a uniform, \unbiased" approach. New coordination primitives are the added to the union of the two calculi which allow actors and-agents to cooperate. The syntax and semantics of actors and-agents are rst deened separately, using a uniform, \unbiased" approach. Since we aim at modeling concurrent distributed systems, a...

one of the most important preparation steps of co-management projects implementation is recognizing key actors at local community level. these actors can assist managers and planners as local leaders and social powers. by applying social network analysis and centrality index at actors’ level of “goormomenin” common rangeland, kalateh region, daamghan city in this research, social powers and loc...

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...
