Principles for the realization of an open simulation framework based on fUML (WIP)

Conference of Symposium on Theory of Modeling and Simulation - DEVS Integrative M and S Symposium, DEVS 2013, Part of the 2013 Spring Simulation Multiconference, SpringSim 2013 ; Conference Date: 7 April 2013 Through 10 April 2013; Conference Code:96780International audienceModel-based engineering is becoming a de facto paradigm for designing complex systems and software. By being executable, models are easier to understand, as well as systems they abstract. UML is the most natural choice for modeling. fUML is an executable subset of UML with precise operational semantics. From causal relations defined in a model, fUML semantics only constructs partial execution orders. When considering fUML in a simulation process, this limitation is possibly an issue for engineers to observe various execution schemes and to have a representative execution of a system model. Usually simulation frameworks control the execution of an application thanks to a dedicated entity. This latter is responsible for the construction of the execution order conforming to the semantics of a specific Model of Computation (MoC). Furthermore it can be used to reflect extra-functional aspects like time. In order to overcome these limitations, this paper proposes principles to use fUML as a simulation environment. We propose to extract the execution control policy from a fUML model and to delegate it to a specific simulation library defining MoCs as fUML models. This library is responsible for controlling the execution and simulating extra-functional aspects. This approach provides the required flexibility and openness needed to support various applications domains. The solution is evaluated on a simple, but representative example

Expeditious synthesis of beta-cycloacetalic sulfoxides. Introducing 1-phenylsulfinyl-2-phenylsulfanylethylene (SOSE), a promising new alkenylsulfur reagent

In similarity with the strongly electrophilic BPSEs and despite its more electron-rich character, 1-phenylsul.nyl-2-phenylsulfanylethylene (SOSE) reacts with nucleophiles with displacement of the phenylthio moiety. Speci.cally it reacts with diols underbasic conditions to produce b-cycloacetalic sulfoxides. The reaction has been amply developed in carbohydrate chemistry
