Abstract: A method for determining technical system parameters using a cost function. The technical system has system parameter-adjustable components. When system parameters are set, the technical system generates component output values. The method includes determining a definition space in which the cost function lies, determining random system parameters in the definition space, applying the random system parameters to the technical system and determining the output values, technical system modeling by training a statistical analysis method, generating technical system rules using the system parameters and the output values, generating probability functions using the rules, each indicating the probability which satisfy the rules by any cost function, combining probability functions to determine the cost function by maximizing overall probability of all rules, optimizing the system parameters given the cost function, and outputting the optimized system parameters for adjusting the technical system components.

Abstract: The invention relates to a plate heat exchanger 1 with at least two cuboidal modules 1a, 1b. The two modules 1a and 1b are cuboidal and are each closed to the outside by cover sheets 5. The two modules 1a and 1b are arranged such that in each case, cover sheets 9a and 9b of the same size are directly adjacent. On the contact surfaces, sections 20a, 20b are welded that prevent movement of the two modules 1a, 1b perpendicular to the contact surfaces 9a, 9b either alone or with an additional formed part 50.

Abstract: A method for producing a plate heat exchanger with at least two heat exchanger blocks which are produced separately from one another in a soldering furnace Each heat exchanger block has multiple separating sheets arranged parallel to one another and which form a plurality of beat exchanger passages for fluids involved in a heat exchange process. At least one support provided with solder is heated in order to melt the solder, the support is arranged between opposing outer surfaces of the heat exchanger blocks to be connected which are placed one on top of the other or adjacently, the support(s) thus being fixed between the opposing outer surfaces. After the solder is hardened, a bonded and heat-conductive connection is produced between the heat exchanger blocks. Sheets or wire arrangement can be used as the supports.

Abstract: The invention relates to a plate heat exchanger with at least two heat exchanger blocks. Each heat exchanger block has several sheets, arranged parallel to one another, that form a plurality of heat-exchange passages for fluids. The heat exchanger blocks are joined to one another via joining means and have at least one common header. A metal foam, that joins the outside surfaces of adjacent heat exchanger blocks to one another, is introduced into an interspace of adjacent heat exchanger blocks. In this way, a blanket heat-conductive and non-positive joining is provided between the opposing outside surfaces of adjacent heat exchanger blocks.

Abstract: Probes are electrically connected to a surface of a tunnel junction film stack comprising a free layer, a tunnel barrier, and a pinned layer. Resistances are determined for a variety of probe spacings and for a number of magnetizations of one of the layers of the stack. The probe spacings are a distance from a length scale, which is related to the Resistance-Area (RA) product of the tunnel junction film stack. Spacings from as small as possible to about 40 times the length scale are used. Beneficially, the smallest spacing between probes used during a resistance measurement is under 100 microns. A measured in-plane MagnetoResistance (MR) curve is determined from the “high” and “low” resistances that occur at the two magnetizations of this layer. The RA product, resistances per square of the free and pinned layers, and perpendicular MR are determined through curve fitting.
