The flow structure around the intake of a vertical pump is investigated experimentally and numerically in order to obtain a guideline in designing the optimum shape of the intake of vertical pumps, in which their installation area is demanded to be minimum without losing the high performance. We concentrate our attention on the expansion ratio of the intake as a representative characteristic of the shape of the pumps and investigate the effect of the expansion ratio on pump performance. It is concluded that the optimum expansion ratio ranges in 1.1-1.2 if we take into consideration that the area needed for the installation of the pump should be minimum.

Chinese Journal of Electrical Engineering 2018年第3期4卷 47-52页

作者： Keiji wada Department of Electronics Engineering and Computer Science Tokyo Metropolitan UniversityTokyo Japan

recently,high di/dt and dv/dt switching operations of power converter circuits has been discussed for realizing a high-efficiency power converter *** this case,parasitic inductances of the bus bar between a DC capacitor and power devices may cause issues of overshoot voltage and electromagnetic interference(EMI)***,it is necessary to design the bus bar geometry while considering the minimization and optimization of the parasitic inductance of bus *** paper discusses a relationship between bus bar geometry and switching *** addition,the bus bar analysis is based on the PEEC method,and the bus bar geometry is designed by considering the stray inductance with using an inductance-map ***,this paper also presents a design procedure of acceptable stray inductance based on a standardization *** should be noted that the stray inductance is designed not for minimization,but optimization,and it is shown not as an absolute value(H),but as a percentage value(%).Finally,the oscillation waveforms under turn-off operation will be discussed depending on the bus bar geometry.

Clues to the signals for chloroplast photorelocation from the lifetimes of accumulation and avoidance responses

引用

Journal of Integrative Plant Biology 2015年第1期57卷 120-126页

作者： Takeshi Higa Masamitsu wada Department of Biology Faculty of Sciences Kyushu University

Chloroplast photo-relocation movement is crucial for plant survival; however, the mechanism of this phenome- non is still poorly understood. Especially, the signal that goes from photoreceptor to chloroplast is unknown, although the photoreceptors （phototropin 1 and 2） have been identified and an actin structure （chloroplast actin filaments） has been characterized that is specific for chloroplast movement. Here, in gametophytes of the fern Adiantum capillus-veneris, gametophores of the moss Physcomiterella patens, and leaves of the seed plant Arabidopsis thaliana, we sought to characterize the signaling system by measuring the lifetime of the induced response. Chloroplast movements were induced by microbeam irradiation with high-intensity blue light and recorded. The lifetime of the avoidance state was measured as a lag time between switching off the beam and the loss of avoidance behavior, and that of the accumulation state was measured as the duration of accumulation behavior following the extinction of the beam. The lifetime for the avoidance response state is approximately 3-4rain and that for the accumulation response is 19-28 rain. These data suggest that the two responses are based on distinct signals.

在有限温度和低密情况下,核物质会发生液汽相变,当密度和压强是共轭变量时,温度是一个控制参量。利用Fisher模型和朗道理论,我们从实验上找到了一个描述非对称核物质相变的新的序参量。中子和质子的不同混合比例作为序参量,对
