Super-Kamiokande is the world's largest water Cherenkov detector, with net mass 50,000 tons. Earth's atmosphere, and the K2K long-baseline neutrino beam with high efficiency. These data provided crucial information for our current understanding of neutrino oscillations, as well as setting stringent limits on nucleon decay. In this paper, we describe the(More)
It is very important to guarantee the quality of the industrial products by means of visual inspection. In order to reduce the soldering defect with terminal deformation and terminal burr in the manufacturing process, this paper proposes a 3D visual inspection system based on a stereo vision with single camera. It is technically noted that the base line of(More)
The atmospheric neutrino ux ratio = e and its zenith angle dependence have been measured in the multi-GeV energy range using an exposure of 25.5 kiloton-years of the Super-Kamiokande detector. By comparing the data to a detailed Monte Carlo simulation, the ratio =e DATA ==e M C was measured to be 0:660:06stat:0:08sys:. In addition, a strong distortion in(More)
The atmospheric neutrino flux ratio ν µ /ν e and its zenith angle dependence have been measured in the multi-GeV energy range using an exposure of 25.5 kiloton-years of the Super-Kamiokande detector. By comparing the data to a detailed Monte Carlo simulation, the ratio (µ/e) DAT A /(µ/e) MC was measured to be 0.66 ± 0.06(stat.) ± 0.08(sys.). In addition, a(More)
