Abstract: In a method for passivating the surface of a tinplate using electrolytic deposition of a passivation layer containing chromium oxide/chromium hydroxide on the surface, the electrolytic deposition of the passivation layer is carried out at least partly from an electrolyte solution which contains a trivalent chromium compound, at least one salt for increasing the conductivity and at least one acid or one base for adjusting a desired pH value and is free from organic complexing agents and free from buffering agents. In order to increase the amount of chromium oxide in the passivation layer, after the electrolytic deposition of the passivation layer, the passivated tinplate is subjected to a thermal treatment in which the passivated tinplate is kept at a treatment temperature of 100° C. or more for a treatment time of at least 0.5 seconds.

Abstract: A method for passivation of the surface of blackplate or tinplate by electrolytic deposition of a chromium oxide-containing passivation layer on the surface. The electrolytic deposition of the chromium-containing passivation layer occurs from an electrolyte solution that contains a trivalent chromium compound as well as at least one salt to increase the conductivity and at least one acid or a base to adjust a desired pH value. The electrolyte solution contains no additional components apart from the trivalent chromium compound as well as the at least one salt and the at least one acid or base and is especially free of organic complexing agents and free of buffering agents.

Abstract: A water supply network includes node components and edge components, wherein the edge components transport water between the node components. The edge components is controllable in relation to its flow behavior for water. A method for controlling the water supply network includes the steps of determining a planning horizon, which includes a number of time slices; determining upper and lower limits for feeds and prospective withdrawals of water in the time slices; determining possible operating configurations of the at least one edge component; determining energy costs for an activation of the edge component in the time slices; determining permissible states of node components; determining current states (initial states) of edge or node components; and determining a control plan for the at least one edge component on the basis of the determined information in such a manner that a predetermined water balance is maintained in each time slice averaged over time.

Every module of the system has a known, first consumption of resources. The first consumption of resources of at least one of the modules is modified according to a predetermined criterion, thereby obtaining a modified system. The modified system is executed. A second consumption of resources is measured for every module of the modified system, the consumption resulting from the modification of the first consumption of resources of the at least one module. An analysis of the second consumption of resources of a respective module and the predetermined criterion is used to determine whether there is a dependency between the respective module and the at least one module that is characterized by the modified consumption of resources.

For n slice planes and a set of sequence parameters that include at least the parameters TRmin: minimal repetition time between two measurement sequences of the same slice plane and TRmax: maximum repetition time between two measurement sequences of the same slice plane, a periodic acquisition scheme that, temporally expanded, is [TRi, TR]-compatible to the k-th degree and has k streams. The association of the n slice planes with the k streams of the acquisition scheme and the order of the slice planes within the respective streams are determined by mixed-integer linear program.
