A system, method and computer program product for generating a data record of a training dataset set configured to train a neural network for determination of the concentration of a particular target molecule in an NMR sample. An NMR spectrum associated with a known concentration of the target molecule is obtained. The obtained NMR spectrum is adjusted by applying a random shift to generate an adjusted NMR spectrum. A background generator adds a background spectrum which reflects contributions of impurities in the NMR sample. The resulting NMR spectrum together with the information about the concentration of the target molecule is then stored as a new data record of the training dataset.

Systems and methods for provisioning training data to enable neural networks to analyze signals in NMR measurements

A method for detecting ionizing radiation using a pixelated semi-conductor detector. When the radiation interacts with the detector, the affected pixel is determined, together with the instant of impact for this pixel. A first instant before and a second instant after the instant of impact are deduced from this. The deviations of the signals coming from an assembly of pixels adjacent to the affected point are then measured, with the deviations being measured between the first and second instants. The position of the point of interaction of the radiation with the semi-conductor is estimated from the deviations thus measured.
