Weighted O-Minimal Hybrid Systems Are More Decidable Than Weighted Timed Automata!
Abstract. We consider weighted o-minimal hybrid systems, which extend classical o-minimal hybrid systems with cost functions. These cost functions are “observer variables” whic...

Towards formal security analysis of GTRBAC using timed automata
An access control system is often viewed as a state transition system. Given a set of access control policies, a general safety requirement in such a system is to determine whethe...

Sampled Semantics of Timed Automata
Sampled semantics of timed automata is a nite approximation of their dense time behavior. While the former is closer to the actual software or hardware systems ed granularity of ti...

Automata and temporal logic over arbitrary linear time
Linear temporal logic was introduced in order to reason about reactive systems. It is often considered with respect to infinite words, to specify the behaviour of long-running sys...

PLC-Automata: A New Class of Implementable Real-Time Automata
We introduce PLC-Automata as a new class of automata which are tailored to deal with real-time properties of Programmable Logic Controllers (PLCs). These devices are often used in...
