Abstract: There is provided a solution for employing a neural network in a radio receiver. According to an aspect, a method comprises: acquiring, from a received frame, a set of samples associated with a position of a control information element in the frame; inputting the set of samples to nodes of an input layer of a neural network, the input layer having the same number of nodes as a number of samples in the set of samples; processing the set of samples in the neural network that has been trained, before receiving the set of samples, to decode one or more determined values of the control information element and to detect discontinuous transmission; outputting, in an output layer of the neural network, an indicator indicating a decoded value of the control information element comprised in the set of samples or an indicator indicating the discontinuous transmission.

Abstract: According to an aspect, there is provided an apparatus comprising at least one processor and at least one memory connected to the at least one processor. The at least one memory stores program instructions that, when executed by the at least one processor, cause the apparatus to determine based on at least one indicator that a camera connected to the apparatus is in a dark environment, initiate a calibration sequence of the camera in response to determining based on the at least one indicator that the camera connected to the apparatus is in a dark environment, capture, during the calibration sequence, multiple images with the camera with different sets of shooting parameters, cause analysis of the captured images to obtain camera calibration data, and store the camera calibration data in a memory of the apparatus.

Abstract: The invention concerns the use of an oil composition for temporarily protecting and lubricating metal surfaces, characterised in that said composition contains: at least 30% of at least a saturated or unsaturated C?18 fatty acid triglyceride (Compound A); 5 to 30% of at least a C?18 fatty acid triglyceride with oleic acid content of at least 60 wt. % (Compound B); 5 to 30% of at least an ester derived from condensation of a C1-C12, preferably, C1-C2 aliphatic alcohol, with a C?18 fatty acid (Compound C); and optionally 5 to 20% of at least an amide derived from condensation of a C?18 ?fatty acid, and a C2-C6 mono- di- or tri-alkanolamine (Compound D). The invention also concerns a corresponding oil composition.

Abstract: Furthermore, the tribological aspect is also improved since the friction coefficient goes from 0.08 with the steel coated with formulation I to 0.06 with the steel coated with formulation II.
