The method may further comprise retrieving the soft information identified by the unique identifier associated with the physical location from the memory, decoding the chunk of data with the soft information indicating reliability of bits in the chunk of data and updating the soft information with decoding information generated during the decoding.

Abstract: An all-optical ultrasonic detection device based on light-induced ultrasound and laser interference. In the device, a first laser is connected to an optical switch, the optical switch is connected to a dielectric film and a second laser generates a reference laser beam and a plurality of detection laser beams. The reference laser beam generates a first frequency-shifted reference laser beam and a plurality of second frequency-shifted reference laser beams. The first frequency-shifted reference laser beam generates a carrier signal. The detection laser beams are reflected by the dielectric film and then interfere with the second frequency-shifted reference laser beams. The interference light passes through a fourth fiber coupler and reaches a second photodiode to generate a frequency-modulated signal. The frequency-modulated signal and the carrier signal are input to a frequency mixer to generate a mixed signal. An acquisition unit is configured to obtain a vibration signal for the to-be-detected object.

Abstract: A denoising optimization method for an AC traction motor by chamfering a stator tooth shoulder includes taking an angular vertex of the stator tooth shoulder as an end point, obtaining two points equidistantly along two sides of a stator tooth shoulder angle from the end point; and using the two points as tangent points D1 and D2 of the inscribed arc; making the inscribed arc of the tooth shoulder angle through the two tangent points D1 and D2, cutting off the tooth shoulder angle along the inscribed arc, and adjusting an oblique height HS1 of a stator tooth pole shoe. The invention obtains optimal values of a chamfering size and oblique height of a stator tooth slot pole shoe by adjusting the oblique height of the stator tooth pole shoe and adopting a particle swarm optimization algorithm.
