In this paper a new way of transporting parts in production systems is described. Based on the fact that in nature the highest speeds are reached at flight, a bio-inspired technical approach for the fast transportation of objects is derived. Objects shall be thrown by a throwing device and are caught again by a catching device. Such a transport approach(More)
View integration is an effective technique for developing large conceptual database models. The universe of discourse is described from the viewpoint of different user groups or parts of the system resulting in a set of external models. In a second step these models have to be integrated into a common conceptual database schema. In this work we present a(More)
The integration of statecharts is part of an integration me thodology for object oriented views Statecharts are the most important language for the representation of the behaviour of objects and are used in many object oriented modeling techniques e g in UML In this paper we focus on the situation where the behaviour of an object type is represented in(More)

The IEC 61850 standard originally was developed for the substation automation. During the last years it was adapted for the integration of distributed energy resources into communication networks. There are however specific requirements in this new field of application. Many small and midsize manufacturers are using as controllers a big variety of different(More)
For object-oriented databases we propose a new technique for optimizing queries containing method invocations. This technique is based on the definition of inverse methods and query rewriting. It can be viewed as providing computed inverted access structures like (secondary) indexes provide stored inverted access structures. This technique can be applied to(More)
Statecharts are a popular representation technique for conceptual models of the dynamics of a universe of discourse. However, designers are not supported in their work with dynamic models as well as they are for working with static models. We present a meta-model and a formalization of the semantics of a statechart language. Important results are the(More)

In a research project the transportation of objects in production systems is realized by throwing and capturing. At the current state of the work, objects with masses up to 100 g are thrown over distances of 3 m. In the current approach the positions of the flying objects are measured on their trajectories by a camera system and a robot is directed to a(More)
