Abstract: A device and a computer-implemented method for testing a machine having a plurality of components or for testing a component of a machine. The method includes: providing a set of input variables for a model, the set of input variables characterizing load factors on the machine or characterizing load factors on at least one component of the machine; selecting a subset of the set; mapping, by the model, the subset to an output variable of the model which characterizes a stress caused by the load factors in the case of at least one component of the machine; and determining a degree of damage, in particular a degree of fatigue, of the at least one component according to a set of output variables which contains the output variable.

Abstract: The invention relates to a smoke detection device 1, said smoke detection device 1 being connectable to at least one monitoring camera 2 which is designed to capture images of a monitored area, said monitored area comprising at least one stationary lighting object 3. The smoke detection device comprises an analyzing device 4, said analyzing device 4 being designed to detect at least one smoke detection feature in the monitored area in order to detect smoke in the images. The analyzing device 4 detects the at least one lighting object in the images, and the analyzing device 4 detects a change of a light scattering of the at least one detected lighting object 3 as the at least one smoke detection feature.
