      A Family of Resource-Bound Real-Time Process Algebras 

      Lee, I.; Philippou, Anna; Sokolsky, O. (2006)
      The Algebra of Communicating Shared Resources (ACSR) is a timed process algebra which extends classical process algebras with the notion of a resource. It takes the view that the timing behavior of a real-time system depends ...
