A device, a method and a computer program for position determination are provided. For the non-machining forming of the brake caliper two mould parts each partially receiving the brake caliper are used, in which support surfaces and action surfaces are formed on the brake caliper in such a way that the brake caliper for the subsequent machining is supportable by its support surfaces in a defined manner and clampable by means of clamping forces acting upon its action surfaces. A sample of the material is treated to diffuse target decay isotopes within the sample such that the measured alpha particle emission directly corresponds to the concentration or number of target decay isotope atoms within the entirety of the sample, enabling the concentration of target decay isotopes in the sample to be determined. From the perspective of the server, a motion-based affiliation initiation request message is received, and based on the message, at least one device is determined to receive a motion-based affiliation request message. A density of the weight member is greater than a density of the shell portion.
