Abstract: A control device includes: a receiving unit, the control device being configured for controlling a technical system including at least one controllable component with respect to a target variable taking into consideration a forecast curve, which is provided with a plurality of values for a plurality of points in time in a future time period by the receiving unit; and an optimizer including an analysis unit configured for analyzing the forecast curve and an approximator configured for specifying an approximated forecast curve, the analysis unit being configured for setting a plurality of supporting points based on analyzed ones of the plurality of values of the forecast curve, and the approximator being configured for specifying the approximated forecast curve with the plurality of supporting points that are set based on the analyzed ones of the plurality of values of the forecast curve.

Abstract: The invention relates to metal dispersions comprising 50 to 80 wt % of silver nanoparticles, 15 to 45 wt % of water and a dispersant, wherein the dispersant comprises copolymers comprising 1-99 wt % of structural units of formula (1), where R is hydrogen or C1-C6 alkyl, A is C2-C4 alkylene group and B is C2-C4 alkylene group with the proviso that A and B are different and m, n are each independently an integer of 1-200, and 1-99 wt % of structural units of formula (2), where Xa is an aromatic or aliphatic radical having 1 to 30 carbon atoms which optionally comprises one or more, for example 1, 2, or 3, heteroatoms N, O and S, Za is H or (C1-C4)-alkyl, Zb is H or (C1-C4)-alkyl and Zc is H or (C1-C4)-alkyl.

Abstract: A system and device phase-aligns and sums signals from a very large array of sensors, such as microphones or ultrasonic transducers, without prior knowledge of time delays of signals reaching each sensor, so as to accommodate effects of reverberant fields or acoustic or ultrasonic media containing multiple reflectors or scatterers and/or having heterogeneous, unknown acoustic properties.

Abstract: A process for preparing 3,4-disubstituted phenylacetic acids of the formula (I) in which X is fluorine, chlorine, bromine or iodine and R is C1-C4-alkylthio, C1-C4-alkylsulfonyl or C1-C4-alkylsulfoxide, starting from a 2-halo-C1-C4-alkylthiobenzene of the formula (II) in which X is as defined above and R1 is C1-C4-alkylthio.
