Pattern recognition for bivariate process mean shifts using feature-based artificial neural network

In multivariate quality control, the artificial neural networks (ANN)-based pattern recognition schemes generally performed better for monitoring bivariate process mean shifts and provided more efficient information for diagnosing the source variable(s) compared to the traditional multivariate statistical process control charting. However, these schemes revealed disadvantages in term of reference bivariate patterns in identifying the joint effect and excess false alarms in identifying stable process condition. In this study, feature-based ANN scheme was investigated for recognizing bivariate correlated patterns. Feature-based input representation was utilized into an ANN training and testing towards strengthening discrimination capability between bivariate normal and bivariate mean shift patterns. Besides indicating an effective diagnosis capability in dealing with low correlation bivariate patterns, the proposed scheme promotes a smaller network size and better monitoring capability as compared to the raw data-based ANN scheme

A measurement of the transverse polarization of Λ-hyperons produced in inelastic pN-reactions at 450 GeV proton energy

A study of the polarization of Λ hyperons produced in inelastic pN reactions induced by the 450 GeV proton beam from the CERN SPS has been performed with the NA48 detector. The Λ hyperons were detected at a fixed angle of 4.2 mrad in the momentum range from 50 GeV/c to 200 GeV/c. The polarization changes from -0.053 ± 0.034 to -0.298 ± 0.074 for a transverse momentum range of the Λ between 0.28 GeV/c and 0.86 GeV/c. The Λ̄ polarization is consistent with zero

Measurement of the decay rate and the parameter alpha(K)* of the decay K-L ->mu mu gamma

The rate of the decay of the neutral K meson into K-L(0) --> mu mu gamma has been measured with the NA48 detector at the CERN SPS, Pi total of 59 events has been observed with an estimated background of 14 events. The overall Kaon flux was determined to he 1.2 x 10(9), This observation corresponds to a branching ratio of (3.4 +/- 0.6(stat) +/- 0.4(sys)) x 10(-7) Using this branching ratio the parameter alpha(K*) describing the relative strength of the two contributing amplitudes to this decay, through intermediate pseudoscalar or vectorlike mesons, was measured to be alpha(K*) = -0.04(-0.21)(+0.24)

A measurement of the transverse polarization of Lambda-hyperons produced in inelastic pN-reactions at 450 GeV proton energy

A study of the polarization of L hyperons produced in inelastic pN reactions induced by the 450 GeV proton beam from the CERN SPS has been performed with the NA48 detector. The L hyperons were detected at a fixed angle of 4.2 mrad in the momentum range from 50 GeV/c to 200 GeV/c. The polarization changes from -0.053 ±0.034 to -0.298 ±0.074 for a transverse momentum range of the L between 0.28 GeV/c and 0.86 GeV/c. The [`(L)] polarization is consistent with zero
