Aquatic ecosystems are natural complex systems. They are the site of a great number of phenomena. Thus, many studies model each of these phenomena, using law-based approach (most of the time differential equations) or rule-based approach (individual-based models in particular). Owing to their complex nature, aquatic ecosystems are hard to study and resist a(More)
Interactions between proteins of the Bcl-2 family play an important role in the regulation of apoptosis. Anti-apoptotic family members can heterodimerize with pro-apoptotic family members and antagonize their function, thus protecting against death. In cells protected from death by overexpression of Bcl-2 much of the Bax is present in Bax/Bcl-2(More)
In this paper, we present a methodology for aquatic ecosystem modeling. We based our model on the holarchic (non directional hierarchic) nature of the ecosystems. Aquatic ecosystems are crossed by structuring fluxes (light radiation , mass transport, etc.) which confer multi-level of emergent organizations. Elsewhere, a part of aquatic ecosystems are(More)
— We propose some ways computer science can be used to help modeling in general and ecological modeling in particular, beyond numerical solving of mathematical models. More precisely we present a summary analysis of ecological modeling following two pairs of criteria (Rules vs. laws and State variables vs IBM), upon which we built an ontological computer(More)
In this article, we are interested in providing a framework to develop games for visually impaired or blind children. In this context, we propose a tool set to ease the creation of such games based on an actor metaphor. As the possible outputs are multimodals (mostly not graphical) we provide an abstract library. The architecture is composed of an engine(More)
This paper deals with aquatic ecosystem model in estuaries context. These systems are described with functional organizations which are producers, consumers and decomposers. We use a hierarchical representation which is based on com-partmental model. The different compartments exchange various fluxes of their global components, like oxygen for example , as(More)
This report gives an overview of our efforts towards a formalization for a food processing demonstrator plant. Our BeSpaceD framework is used for the formalization. The formalization comprises properties of components and relations between components. We present domain-specific constructs for the formalization of industrial automation facilities and provide(More)
Our endeavour for modelling estuarial ecosystems led us to represent them as complex systems where interactions of various nature and space time scale take place. It is indeed an ecosystem under a strong human influence, consisting in entities of various natures, for instance biological or chemical, interacting in non trivial ways (e.g. non linearly, with(More)
