Distributed Model Management Platform For Virtual Enterprise Networks

Abstract

Virtual enterprise networic planning and design lead to complex challenges. From a conceptual point of view, business processes have proven to be the ideal design items in conjunction with the use of graphical methods and tools. Especially for network design and implementation, information modelling serves as the fundamental starting point. In the article, the authors depict a modelling approach dedicated to a global and a local description of business processes and a distributed model management platform, Tlte latter supports the collaborative creation and application of models in network environments.

Microlensing with an advanced contour integration algorithm: Green's theorem to third order, error control, optimal sampling and limb darkening

“…Such an expression holds also when a part of the source is inside a caustic (Dominik 1995; Gould & Gaucherel 1997).…”

“…Green's theorem was then used for calculating areas by Dominik (1993). The method has been refined by Dominik (1995) and then applied to microlensing by Gould & Gaucherel (1997) and Dominik (1998). The appeal of this method is that a two‐dimensional calculation is turned into a one‐dimensional calculation, which is much faster, in principle.…”
