Abstract: A method and device for evaporating a predeterminable volume of fluid includes successive addition of partial volumes of the predeterminable volume to a supply line at different adding rates, at least partially evaporating the partial volumes forming vapor film between them and a supply line wall, conveying the partial volumes through the supply line to an evaporator surface, and applying the partial volumes to an evaporator surface region varying as a function of mass and/or volume adding rate of the partial volume, permitting effective evaporation of fluid, particularly urea/water solution. Utilization of the highest possible proportion of evaporator surfaces is achieved by mass and/or volume addition rate-dependent distribution of impingement surfaces on the evaporator surface. This heating strategy in the supply line region ensures the Leidenfrost effect when individual partial volumes are added.

Regions between the nanostructures are filled with at least one material constituting a reaction partner with respect to the material of the nanostructures. A method for producing at least one bonding substrate and a reactive multilayer system, includes, for forming the reactive multilayer system, at least one surface layer of the bonding substrate is patterned or deposited in patterned fashion with the formation of vertically oriented nanostructures spaced apart from one another, and regions between the nanostructures are filled with at least one material constituting a reaction partner with respect to the material of the nanostructures.

Abstract: An electronic component for an integrated mechatronic system has at least two housing parts with at least one housing base, a housing cover, and an electrical connection between the components disposed in the interior of the housing and components located outside the housing. The electrical connection is fixed on the housing base. The housing cover is glued directly to the electrical connection and/or the housing base and, in this manner, enables lasting hermetically sealed protection for the sensitive electronic components.
Abstract: The invention relates to a guide-vane arrangement (1) for deviating the flow present in the by-pass flow channel (2) of an engine (3), said arrangement comprising an outer ring (4) and an inner ring (5) and guide vanes (6) arranged therebetween in a substantially radial manner, wherein the outer ring (4) has elements (7) for connecting to an outer engine structure (8), and the inner ring (5) has elements (9) for connecting to an inner engine structure (10), with a plurality of segments (11) being provided.
Abstract: Before image data are screened for the subsequent exposure of a printing form, files needed for the screening step are changed in such a way that the values of individual elements in the data fields are changed. The number of elements whose values are changed is determined by evaluating contiguous regions within the data fields. These can be, for example, threshold value matrices in which individual matrix elements are set to a value corresponding to the color white, or which, for the half-tones, are calibrated to a reduced value of the full-tone density. In the latter case, the full-tone image points are screened with a frequency-modulated screen.
Abstract: An effective method for managing product segments of product production rules within a manufacturing execution system adapted for providing a final product includes the following steps: a) each one of a plurality of sets of product segments are associated within one of a set of product production rules which are stored in a database under a reference standard product production rule (like a simple “manufacture of a car”); b) a command (e.g.
Abstract: A method of identifying transportation items which are physically different from one another, particularly for identifying automatically sortable passenger luggage in air, rail, or ocean travel, using electronically readable information associated with the transportation item.
Abstract: A rail vehicle contains a floor plate, which is supported on a shell floor plate with height adjustment elements therebetween. The height adjustment elements have two components arranged one over the other, of which the one rests against the floor plate from below and the other rests against the shell floor plate from above, wherein the two components can be fixed in various positions relative to each other in order to set a total height of the height adjustment elements.
Abstract: A flux-focused, shaped permanent magnet includes a body of magnetic material having multiple surface contouring to form a reduced flux side with convex surfaces and an increased flux side with concave surfaces. The surfaces develop high and low resistance external flux paths creating focused asymmetric flux fields. A magnetic unit having the shaped permanent magnet and a magnetic flux attracter or two shaped permanent magnets interconnected by two segmented permanent magnets and a kinetic device having a stationary stator ring, a rotor disc rotating within the stator ring and a multiplicity of the magnetic units on the stator ring and the rotor disc, are also provided.
Abstract: A method and a device are provided for crosstalk evaluation of a channel, wherein the channel is represented and/or modeled by a multiple-input-multiple-output (MIMO) system connecting a first network component with at least one second network component. The MIMO system contains first coefficients associated with transmission lines that are in particular associated with crosstalk. The crosstalk contains a near-end crosstalk (NEXT) portion and a far-end crosstalk (FEXT) portion. The first network component sends a signal to one second network component; the far-end crosstalk portion and the near end crosstalk portion are evaluated.
Abstract: An optical noise signal is added to an optical data signal on the receiver side, and a signal quality of the data signal is determined. The magnitude of the added noise signal is varied, and a function of the signal quality of the data signal is determined in dependence on the added noise signal. Subsequently, a first straight line is approximated to the previously determined function for smaller values of the added noise signal, and a second straight line for larger values of the added noise signal. The optical signal-to-noise ratio is read from the intersecting point of the first straight line with the second straight line. Thus, the ASE present is derived from the controlled addition of additional ASEs, and the optical signal-to-noise ratio is determined. The process is particularly suited for DWDM systems because it works even with very narrow channel separations, or with narrowband optical filtration along the separation.
Abstract: A device for recognizing a mechanical defect in a wire of an overhead line. A device for determining the tension in the wire is connected to the wire and a support. The device is connected to an analytical device for comparing the tension with a set value and for indicating a mechanical defect when the value drops below the set value.

Abstract: Optoelectrical conversion of the received optical service signal (OSS), bandpass filtering and subsequent squaring produce a spectral line at the clock frequency (fT). This clock line (TL) is selected by means of narrowband filtering and rectified. The service signal voltage (VTLM) obtained in this manner is used to switch on a Raman pump laser (11).
