Security-critical systems are an important application area for formal methods. However, such systems often contain cryptographic subsystems. The natural definitions of these subsy...
The focus of my thesis is on the development of a multi-method framework for the validation of formal models (domain model, user model, and teaching model) for adaptive work-integr...
In the previous two decades, a number of qualitative constraint calculi have been developed, which are used to represent and reason about spatial configurations. A common property...
