On the Computational Complexity of Verifying One-Counter Processes
—One-counter processes are pushdown systems over a singleton stack alphabet (plus a stack-bottom symbol). We study the complexity of two closely related verification problems ov...

NORA/HAMMR: Making Deduction-Based Software Component Retrieval Practical
Deduction-based software component retrieval uses preand postconditions as indexes and search keys and an automated theorem prover (ATP) to check whether a component matches. This...

Network invariants for real-time systems
We extend the approach of model checking parameterized networks of processes by means of network invariants to the setting of real-time systems. We introduce timed transition stru...

Vacuity in Testing
Abstract. In recent years, we see a growing awareness to the importance of assessing the quality of specifications. In the context of model checking, this can be done by analyzing ...

New higher-order active contour energies for network extraction
Using the framework of higher-order active contours, we present a new quadratic continuation energy for the extraction of line networks (e.g. road, hydrographic, vascular) in the ...
