A unified approach is proposed to support the rapid development of editors such as pen-based structured diagrams. This approach uses Constraint Multiset Grammars to describe the context or positional relationships among handwritten strokes and other objects. The resulting description can then be used to interpret ambiguous results of pattern matching techniques. We have implemented this approac...

Es wird ein Verfahren zur Herstellung patientenspezifischer Annuloplastieringe vorgestellt. Der Mitralklappenannulus wird aus Computertomographiebildern modelliert. Eine optimale Ringgeometrie wird interaktiv erstellt. Die Ringe werden mittels Selective Laser Melting aus einer Titanlegierung hergestellt. Im Tierversuch wurde die Machbarkeit des Verfahrens überprüft. Mit patientenspezifisch gefo...

This paper presents KOOL, a concurrent, dynamic, objectoriented language defined in rewriting logic. KOOL has been designed as an experimental language, with a focus on making the language easy to extend. This is done by taking advantage of the flexibility provided by rewriting logic, which allows for the rapid prototyping of new language features. An example of this process is illustrated by s...

Considering that computer-aided-design (CAD) based technology is advancing, it is surprising how time-consuming and complex applications are. If there is no other new way to help designers, then not only will the whole design process become more difficult, but the quality of the final product will not be promising. Also, generating prototype designs in the early stages of development tends to r...

Inspired by Venn diagram layouts, the Treemap [6] is one of the most prevalent implicit tree visualization techniques. Ever since its publication, it has been modified and extended in many ways. This work presents a way to generate 3-dimensional Treemap visualizations by a 4-step procedure. It can be used for rapid prototyping and comparing different 3D Treemap layout approaches, to devise user...
