because of water shortage in arid and semi-arid regions, reuse of wastewater and treated effluents for agricultural irrigation has become an essential matter now. while these kinds of water contain a lot of nutrients such as nitrogen, by using them we could be able to increase the soil fertility and decrease both the chemical nutrient consumption and the costs of agricultural production. howeve...

The duality properties of Peti Nets (PN) are exploiled in order to apply an algorithmfor the calculation of colored S-invaiants of Predicate Transition nets (Pr/T nets) to the calculation of the colored T-invariants.

Well-Structured Transitions Systems (WSTS) constitute a generic class of infinite-state systems for which several properties like coverability remain decidable. The family of coverability languages that they generate is an appropriate criterium for measuring their expressiveness. Here we establish that Petri Data nets (PDNs) and Timed Petri nets (TdPNs), two powerful classes of WSTS are equival...
