OPUS is an elementary calculus that models object-orientation. It expresses in a direct way the crucial features of object-oriented programming such as objects, encapsulation, mess...
We present a general approach for verifying safety properties of Lustre programs automatically. Key aspects of the approach are the choice of an expressive first-order logic in wh...
Symplectic integrators are numerical integration schemes for hamiltonian systems. The integration step is an explicit symplectic map. We find symplectic integrators using universa...
Abstract This note discusses a verification in PVS of the AID (Application Identifier) class from JavaCard's API. The properties that are verified are formulated in the interf...
In this paper we propose a general approach for reasoning in space. The approach is composed of a set of two general constraints to govern the spatial relationships between object...
