  • Circuit, parallel computing device, computer system and computer readable storage medium
    Patent number: 9984026
    Abstract: Provided is a parallel computing system that has scalability and is capable of performing data transfer between desired PEs. Also provided is a computer system that utilizes the parallel computing system described above, and enables radiosity processing on small-scale mobile terminal devices. An HXNet is implemented in a VLSI, and data transfer between VLSIs is possible using additional BMs. Scalability is realized that enables selection of any number of VLSIs, and radiosity processing is enabled on small-scale mobile terminal devices.

  • Method for measuring gamma-rays of radionuclides, particularly in primary water of nuclear reactor
    Patent number: 5574758
    Abstract: A gamma-rays measurement method of radionucludes (iodine-131, cobalt-60, etc.) coexisting with radionuclides (nitrogen-13, fluorine-18, cobalt-58, etc.) each emitting a pair of annihilation gamma-rays, particularly in primary water of a nuclear reactor by the use of a gamma-ray spectrometric system which includes a primary detector for detecting the gamma-rays and the one annihilation gamma-rays as pulses, a secondary detector for detecting the other annihilation gamma-rays as pulses, and shield detector for detecting gamma-rays Compton-scattered and escaped from the primary to shield detectors as pulses. The method comprises counting the pulses of the secondary detector in anticoincidence with the pulses of the primary detector, thereby to reject the recording of the annihilation gamma-rays from the primary detector, thus minimizing the annihilation gamma-rays disturbing to the measurement, followed by determining count numbers of the gamma-rays.
