A Timed Calculus for Distributed Objects with Clocks
This paper proposes a formalism for reasoning about distributed object-oriented computations. The formalism is an extension of Milner’s CCS with the notion of local time. It allo...

An Inverse Method for Parametric Timed Automata
Given a timed automaton with parametric timings, our objective is to describe a procedure for deriving constraints on the parametric timings in order to ensure that, for each valu...

Foundation for a Time Interval Access Control Model
A new model for representing temporal access control policies is introduced. In this model, temporal authorizations are represented by time attributes associated with both subjects...

Computing Optimal Coverability Costs in Priced Timed Petri Nets
—We consider timed Petri nets, i.e., unbounded Petri nets where each token carries a real-valued clock. Transition arcs are labeled with time intervals, which specify constraints...

Optimal Correspondences from Pairwise Constraints
Correspondence problems are of great importance in computer vision. They appear as subtasks in many applications such as object recognition, merging partial 3D reconstructions a...
