  • Patent number: 11843514
    Abstract: A computer-implemented method for restructuring a predefined distributed real-time simulation network, wherein the simulation network has a plurality of network nodes and a plurality of data connections, wherein each network node has at least one data connection interface for connecting a data connection, wherein the network nodes are at least partially in communication via the data connections, and wherein during operation of the simulation network a simulation application is executed on at least one network node. The method permits a structure for the real-time simulation network to be automatically found in which the critical communication connections are reduced and avoided as much as possible by determining the topology of the simulation network so that topology information concerning the network nodes and the data connections between the network nodes is available by determining expected values for node data rates or node latencies for the network nodes of the simulation network.

  • Publication number: 20230394742
    Abstract: A method for parameterizing a program logic for image synthesis to adapt images synthesized by the program logic to a camera model. A digital photograph of a three-dimensional scene is processed by a neural network and an abstract first representation of the photograph is extracted from a selection of layers of the neural network. The program logic is parameterized according to an initial set of output parameters in order to synthesize an image that recreates the photograph from a three-dimensional model of the scene. The synthetic image is processed by the same neural network, an abstract second representation of the synthetic image is extracted from the same selection of layers, and a distance between the synthetic image and the photograph is calculated based on a metric that takes into account the first representation and the second representation.

  • Publication number: 20230367561
    Abstract: A method for generating source code from one or more blocks of a block diagram, wherein received changes to model elements of the block diagram are stored. The generation of source code includes transforming the block diagram into an intermediate representation, successively optimizing the intermediate representation, and translating the optimized intermediate representation into source code. In this case, at least one plausibility rule is checked for changed model elements. If the plausibility rule is not satisfied, a warning is issued. A user can check mark the change to avoid seeing warnings repeatedly. Furthermore, the invention relates to a method for configuring a control unit, a computer program product and a computer system.
