  • Publication number: 20210279606
    Abstract: Systems and methods are described for adding new attributes to entities of a knowledge base. A plurality of correlations may be identified between the new attribute and existing attributes of the entities using a rule-based model, such that attribute rules may be associated with each identified correlation exceeding a predetermined confidence threshold. An unstructured data model may then be applied to the knowledge base to identify unstructured data associated with each entity of the plurality of entities correlated to presence of the new attribute. Then a meta learner model may be applied to identify weights for each attribute rule and the identified unstructured data. After the weights have been set for the meta learner model, the meta learner model may then be applied to each entity in the knowledge base to accurately identify entities having the new attribute.

  • Publication number: 20210190271
    Abstract: A production method can include flowing a heterogeneous fluid mixture into contact with a homogenizing cutting tool, measuring a fluid mixture temperature so as to obtain a measured fluid mixture temperature, and determining a target fluid mixture temperature. The fluid mixture can be frictionally heated so as to obtain a heated and homogenized fluid mixture by driving the cutting tool at a rate based on (i) the target fluid mixture temperature and (ii) the measured fluid mixture temperature. The heated and homogenized fluid mixture can be flowed away from the cutting tool.

  • Publication number: 20200353775
    Abstract: A vehicle wheel arrangement may have a wheel with a wheel hub and a carrier element for mounting the wheel on a vehicle part and/or for the arrangement of a power-transmitting unit. The wheel hub may have a joining portion, which in a joined state of the vehicle wheel arrangement corresponds with a joining portion of the carrier element. Surface profiles of the joining portions are configured such that, in the joined state of the vehicle wheel arrangement, the wheel hub and the carrier element are connected to one another in form-fitting fashion at least in a circumferential direction of the wheel hub axis. Furthermore, a method can be used to produce a vehicle wheel arrangement having a wheel hub comprised of fiber-reinforced composite and a carrier element.

  • Publication number: 20200282766
    Abstract: A vehicle wheel may include a wheel rim and a wheel disc connected to an inner side of the wheel rim. The wheel disc may be connected to the wheel rim by a connecting element that is guided through a through-hole of the rim base and inserted in the wheel disc. The through-hole is arranged in the tire seat of the rim base and the connecting element is joined substantially in the direction of the radial extension of the wheel disc which is associated to the tire seat on the inner side of the rim. In the method for producing the wheel the connection between wheel rim and wheel disc is produced in the region of the tire seat of the rim base, and, after the insertion of the connecting element into the wheel disc, a portion of the connecting element protruding the contour of the outer side of the rim of the tire seat is shaped so that the connecting element conforms to the contour of the outer side of the rim of the tire seat.

  • Patent number: 10479031
    Abstract: The invention relates to a method and a device for infiltrating a fiber preform of a component of fiber composite material with a matrix material. On the method side, it is proposed that an elastic coating (3) is applied onto the fiber preform (1, 23, 37), wherein the elastic coating (3) is widened to form a gap space (22) between the fiber preform (1) and the coating (3). The matrix material (21) is then fed into the gap space (22) and the elastic coating (3) is subsequently pressed against the fiber preform (1, 23, 37). On the device side, it is claimed that an elastic coating (3) is arranged on the fiber preform (1, 23, 37) and means are provided, which are in operative connection with the elastic coating (3), by which the coating (3) can be widened while forming a gap space (22) between the fiber preform (1, 23, 37) and the coating (3). A matrix material (21) can be fed into the gap space (22) and the coating (3) can be pressed against the fiber preform (1, 23, 37).
