    摘要: A method of constructing an enveloping mesh geometry (EMG) for a plurality of sample mesh geometries (MG). The enveloping mesh geometry is a geometric representation of the mean of the probability distribution underlying the sample space from which the enveloping mesh geometry (MG) have been drawn. The method is based on estimating probability densities fj using the kernel density method. The method further comprises constructing, based on the enveloping mesh geometry (EMG) so constructed, further enveloping mesh geometries (EMG-α) related to the α-Quantiles of the probability distribution. The enveloping mesh geometries (EMG, MG-α) are suitable for development and test procedures in aircraft and automotive manufacturing processes.

    摘要: A valve comprises a valve housing (2) with a valve inlet (11), a valve outlet (12) and a passage (66) extending through the valve housing (2) from the valve inlet (11) to the valve outlet (12). A valve seat (5) is provided in the passage which comprises a valve sealing surface (50). Further, the valve comprises a blocking element (3) adapted to be moved at least partly into the valve seat (5) for blocking the passage by abutment on the valve sealing surface (50), the blocking element being moved along a direction (102) extending under an acute angle to the plane (90) in which the valve seat (5) is arranged. The valve sealing surface (50) of the valve seat (5) is spherical in shape.
