  • Publication number: 20180147795
    Abstract: A method and an automatic layup system for making a stack of a plurality of composite plies are presented. The automatic layup system includes a stacking assembly located in a first plane and a layup tool located in a second plane parallel to the first plane. The stacking assembly and the layup tool are movable towards each other. The method includes the steps of (a) providing one or more composite sheets between the layup tool and the stacking assembly, (b) generating a first composite ply from the one or more composite sheets, (c) placing the first composite ply on the layup tool by the stacking assembly by bringing the stacking assembly and the layup tool close to each other, and (d) repeating the steps (b) and (c) for generating and placing a second composite ply on the first composite ply, which is placed on the layup tool.

  • Publication number: 20180143279
    Abstract: In a method and computer for automatic determination of parameters for an examination with a magnetic resonance apparatus, a modeling is determined that establishes a relationship between the parameters and relations. Each relation describes a mathematical relationship between the parameters of the respective relation. To this end, values or ranges of values of specific of the parameters are acquired, which are predetermined by a user of the magnetic resonance apparatus. The parameters are determined such that the relations are complied with.

  • Publication number: 20180074145
    Abstract: In order to execute a low-artifact magnetic resonance fingerprinting (MRF) scan, a preferred order of N k-space trajectories of a sampling pattern is determined in a computer, along which in each case an undersampled scan data set is to be scanned, such that artifacts are avoided in parameter maps created from the scan data sets in an MRF scan. The order in which the N k-space trajectories are to be sampled one after the other is varied, so at least two different orders are produced. According to the orders that result due to this variation, determined test signal characteristics are compared with each other and/or with ideal signal characteristics with respect to their artifact behavior. A preferred order is determined from the resulting orders by taking into account the results of the comparison.
