We present Crowbar, a deductive verification tool for the Active Object language ABS.
Crowbar implements novel specification approaches specifically for distributed systems. For …

ABS is a language for behavioral modeling of distributed, time-and resource-sensitive
communicating systems. ABS is based on an executable actor-based semantics with …

From the very outset of the digital era, the protection of personal data against unauthorized
usage and distribution has been one of the most significant challenges in distributed …

We present a post-region-based verification system for distributed hybrid systems modeled
with Hybrid Active Objects. The post-region of a class method is the region of the state space …

This article addresses the long-standing problem of program correctness for programs that
describe systems of parallel executing processes. We propose a new method for proving …

The servitization of business makes companies increasingly dependent on providing
carefully designed user experiences for their service offerings. User journeys model services …

Active objects provide a powerful conceptual model of distributed systems. This paper
presents an extension of a locally abstract, globally concrete trace semantics of an active …

We present a post-region-based verification system for distributed hybrid systems modeled
with Hybrid Active Objects. The post-region of a class method is the region of the state space …

The overall problem addressed in this paper is the long-standing problem of program
correctness, and in particular programs that describe systems of parallel executing …
