The efficiency of rank tests for the location in the one and two sample case based on grouped data is compared with the Wilcoxon signed-rank test and with the Mann-Whitney-Wilcoxon test respectively. These efficiencies are calculated for some Box-Tiao densities and different numbers of groups....

Carbon capture from conventional power cycles is accompanied by a significant loss of efficiency. One process concept with a potential for better performance is chemical-looping combustion (CLC). CLC uses a metal oxide to oxidize the fuel, and the reduced metal is then re-oxidized in a second...

The question of delay management is whether trains should wait for a delayed feeder train or should depart on time. In classical delay management models passengers always take their originally planned route. In this paper, we propose a model where re-routing of passengers is incorporated. To...
