Slope is susceptible to rainfall-induced failure after being damaged by earthquake. In this study, the seepage and deformation of unsaturated slope during post-earthquake rainfall were investigated using finite element method. Shaking-induced plastic modulus reduction dependent on deviatoric strain shaking-induced permeability change volumetric considered in modeling response following rainfall...

The power of the medical centrifuge is provided by permanent magnet synchronous motor, so AC control system motor directly determines overall performance centrifuge. In this paper, controlled object, DSP28335 used as main chip, and combined with vector strategy, servo designed. Finally, according to design scheme, soft hard completed, test carried out. results show that designed has fast respon...

We use an optical centrifuge to align asymmetric top SO_{2} molecules by adiabatically spinning their most polarizable O-O axis. The effective centrifugal potential in the rotating frame confines the sulfur atoms to the plane of the laser-induced rotation, leading to the planar molecular alignment that persists after the molecules are released from the centrifuge. The periodic appearance of the...
