Abstract: A method and system for generating a target map for training a neural network and obtaining a sound source map regardless of the maximum number of sound sources, having a short computation time for inference, high spatial resolution and high sound source accuracy. The method includes generating grids each having a spacing within a given range at positions where sound sources are present in order to form a sound source map, calculating a result value for each of coordinates of the grids so that the result value is a local maximum at the position of a sound source and the result value decreases depending on the distance from the sound source, arranging the result values at positions on matrices corresponding to the respective coordinates of the grids, and generating a target map having an image form by using the result values arranged in on the matrices.

Abstract: A charged particle beam apparatus includes: a stage on which a sample is placed; a first charged particle beam unit comprising a charged particle source, a detector, and a first objective lens configured to irradiate a sample with a charged particle beam of charged particles generated by the charged particle source and induce secondary electrons generated from the sample to the detector; and a second charged particle beam unit comprising a second objective lens. An incoming electric field is generated between the first objective lens and the sample to pull the secondary electrons into the first objective lens. An induced electric field is generated between the second objective lens and the sample to guide the secondary electrons to travel to the detector.

Abstract: The present application relates to a system, device, and method for monitoring an abnormal state of pipe, which monitors whether a pipe is abnormal. In the present application, a pipe state signal input from each signal acquisition part is divided into a plurality of time periods, and then it is determined whether an abnormal state signal exists in the pipe state signal in each of the time periods. Therefore, the present application enables determination with higher accuracy of whether the pipe is abnormal, compared to the case of determining whether an abnormal state signal exists in a pipe state signal which has not been divided into a plurality of time periods.
