Wouldn’t it be nice to be able to conveniently use ordinary real number expressions within proof assistants? In this paper we outline how this can be done within a theorem provin...
Abstract. Control diagrams are routinely used by engineers in the design of control systems. Yet, currently the formal verification of programs that implement the diagrams is a ch...
Abstract. Role-based access control (RBAC) is recognized as an excellent model for access control in large-scale networked applications. Formalization of RBAC in a logical approach...
In this paper we present a highly modular planning system architecture. It is based on a proper formal account of hybrid planning, which allows for the formal definition of (flex...
Abstract. This paper describes a query algebra for tolog, a query language for Topic Maps inspired by Prolog and very similar to Datalog. The language is based on binding variables...
