While the European Union (EU) has one of the most extensive and sophisticated supranational water policyworldwide, its transboundary governance framework has certain structural deficiencies that may eventually giverise to ...
Cím: Restricted r-Stirling Numbers and Their Combinatorial Applications
Szerző: ; ; ;
Dátum: 2019

We study set partitions with r distinguished elements and block sizes found in an arbitrary index set S . The enumeration of these ( S, r )-partitions leads to the introduc- tion of ( S, r )-Stirling numbers, an extremely ...
Cím: Adjustment of Reactor Model in Organic Matter Removal from Wastewater Applying Numerical Residence Time Distribution Analysis
Szerző:
Dátum: 2019

We investigate mixed partitions with extra condition on the sizes of the blocks. We give a general formula and the generating function. We consider in more details a special case, determining the generating functions, some ...
Cím: Analysis of a Mechanical Mixer Performance in Anoxic Reactor
Szerző: ;
Dátum: 2019
