A railway crew scheduling problem is an assignment problem of crews for a given operational schedule under the constraint on labor regulations. In this paper, we discuss an automatic railway crew scheduling method based on numerical optimization for a large-scale and complex railway route with branch lines and multiple bases. The proposed method makes the crew schedule automatically using step by step optimization based on a partial pairing, an elastic embedded set partitioning problem and a graph partitioning.

In harmonic analysis of periodic wave, the discontinuity at the boundary of observation interval increases the spectral leakage. Several temporal windows have been developed to improve the spectral resolution. In Fourier transformation, input signal is transformed into complex data consisting of amplitude and phase. This paper describes the phase transmission characteristics of temporal windows. The phase preservability that the phase of input sinusoidal wave is preserved in peak component, can be improved by applying the windows. Phase error caused by the other harmonics depends on the amplitude transmission characteristics of windows, especially on their band-width. The spectral peak moves from <i>n</i>-th bin to (<i>n</i>+1)-th bin with the increase of input frequency. The frequency, at which the peak is shifted from <i>n</i> to <i>n</i>+1, becomes close to <i>n</i>+0.5 through temporal windows. Experiments of pitch-frequency detection using phase compensation method show that Hanning window and Cos window are more desirable than the others.<br>As a result, the temporal window improves the phase transmission characteristics.

A pneumatic nozzle flapper is widely used in pneumatic control systems and is one of the important converting elements. Its transient pressure response has been investigated in several papers, but the case with small time constant has not been reported so far. This paper shows experimentally that the time constant of pneumatic nozzle flapper varies with the direction of pressure step and the position of load capacitor.<br>In the case with steady flow through the load capacitor, the time constant is larger in general than that of side-capacitor, and the time constant of negative pressure response is smaller than that of positive one. These differences are considered to be caused by the heat conduction between air and the capacitor wall.
