A Calculus for Shapes in Time and Space
We present a spatial and temporal logic based on Duration Calculus for the specification and verification of mobile real-time systems. We demonstrate the use of the formalism and...

Spatio-Temporal Configurations of Dynamics Points in a 1D Space
This paper describes a spatio-temporal configurations building approach, which has been applied to dynamics points in 1-dimensional space. In this approach, a temporal logic, Allen...

On Topological Elementary Equivalence of Spatial Databases
We consider spatial databases and queries definable using first-order logic and real polynomial inequalities. We are interested in topological queries: queries whose result only ...
