Symplectic integrators are numerical integration schemes for hamiltonian systems. The integration step is an explicit symplectic map. We find symplectic integrators using universa...

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...
Many papers have been written on the structural aspect of view mechanisms for object-oriented databases. A clean model that focuses speci cally on the interplay between methods an...
