Abstract: A method for providing calibration data for calibrating antenna diagrams of devices configured to transmit and/or receive electromagnetic radiation and belong to a common type series. The method includes: a) selecting a set of devices from the type series for creating a training file; b) for each selected device: measuring a target diagram with a first number of measurement points, and creating an associated source diagram with a second number of measurement points that is less than the first number, and storing the target and source diagrams in the training file; c) using the training file to train a neural network to determine, based on the source diagrams, the respective associated target diagrams; d) measuring the source diagrams of the other devices from the type series ; e) creating the associated target diagrams using the neural network; and f) using these target diagrams as calibration data for the other devices.

Abstract: A mass flow sensor assembly for a mass flow controller or a mass flow meter comprises a mass flow sensor comprising a capillary tube held by a first corner support and a second corner support formed separately from each other. The capillary tube comprises a sensor portion which is located between the two corner supports, and wherein the two corner supports each have an arc-shaped groove in which the capillary tube is partially received. In addition, a method of manufacturing a mass flow sensor assembly is described.

Abstract: A system is described for configuring another system, e.g., a robotics system. The other system interacts with an environment according to a deterministic policy by repeatedly obtaining, from a sensor, sensor data indicative of a state of the environment, determining a current action, and providing, to an actuator, actuator data causing the actuator to effect the current action in the environment. To configure the other system, the system optimizes a loss function based on an accumulated reward distribution with respect to a set of parameters of the policy. The accumulated reward distribution includes an action probability of an action of a previous interaction log being performed according to the current set of parameters. The action probability is approximated using a probability distribution defined by an action selected by the deterministic policy according to the current set of parameters.

Abstract: A method for devising an optimum control policy of a controller for controlling a system includes optimizing at least one parameter that characterizes the control policy. A Gaussian process model is used to model expected dynamics of the system. The optimization optimizes a cost function which depends on the control policy and the Gaussian process model with respect to the at least one parameter. The optimization is carried out by evaluating at least one gradient of the cost function with respect to the at least one parameter. For an evaluation of the cost function a temporal evolution of a state of the system is computed using the control policy and the Gaussian process model. The cost function depends on an evaluation of an expectation value of a cost function under a probability density of an augmented state at time steps.
