We present a process algebra suitable to the modelling of timed concurrent systems and to their efficient verification through model checking. The algebra is provided with two con...
Symplectic integrators are numerical integration schemes for hamiltonian systems. The integration step is an explicit symplectic map. We find symplectic integrators using universa...
A Datalog program can be translated into a system of fixpoint equations of relational algebra; this paper studies how such a system can be solved and optimized for a particular qu...
Reification of parthood relations according to the SEP-triplet encoding pattern has been employed in the clinical terminology SNOMED CT to simulate transitivity of the part-of rel...

Abstract. In [11], we proposed an algebra with four algebraic operators, whose composition can be used to generate valid compound terms in a given faceted taxonomy in an efficient ...
