The main accelerator system of the proposed research facility FAIR is the two stage synchrotron complex SIS100/300, consisting of two separate synchrotron accelerators with equal circumferences. SIS100/300 shall provide beams of protons and heavy ions with high intensities and high energies. The existing GSI accelerators UNILAC and SIS18 shall serve as injector for SIS100/300. SIS100 will be de...

The creation and manipulation of conceptual shapes need different modeling techniques from what are available in present CAD systems. Conceptual modeling techniques are supposed to provide more flexible interaction and mimic working with true materials. Therefore, this paper proposes a new computer internal modeling technique that supports the natural ways of exteriorizing shape concepts as wel...

EADOCS (expert assisted design of composite structures) is a multi-level conceptual design system, in which case-based reasoning is applied to quantify a qualitative prototype solution. Design specifications and targets for case-based retrieval comprise functional requirements, preferred and prototype solutions. Specified design problems cannot be decomposed into tractable subproblems for the r...
