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 ...

"Extreme precipitation events can trigger flash flood, mass movements, pluvial flood and accelerated soil erosion. As soil structures are highly degraded due to intensive improper cultivation water infiltration can ...
Cím: Adjustment of Reactor Model in Organic Matter Removal from Wastewater Applying Numerical Residence Time Distribution Analysis
Szerző:
Dátum: 2019
