Visual description techniques are particularly important for the design of hybrid systems because specifications of such systems must usually be discussed between engineers from a ...
Meta-modeling is well known to define the basic concepts of domain-specific languages in an object-oriented way. Based on graph transformation, an abstract meta-model may be enhanc...
We have been working on a unit system for end-user spreadsheets that is based on the concrete notion of units of the abstract concept of types. In previous work, we defined such ...

The development and use of ontologies may require users with no training in formal logic to handle complex concept descriptions. To aid such users, we propose a new visualization f...
