Simulation of the effect of the drift velocity line shape on the vertical transport in doped GaAs/AlAs superlattice with weak coupling;

Application of simulated calculation for superlattice vertical transport with MATLAB;

Measurements of the vertical transport I-V curves of two type-I GaAs/AlAs superlattice samples with doped wells and weak coupling between wells are performed with quasistatic sweeping and high-speed sweeping of the bias.

Based on the measured data in 2003,the longitudinal material transport model was employed to calculate the longitudinal transport of water and sediment in the west channel of Lingdingyang Bay during ghe flood season with spring tides.

The test results show that the longitudinal motions of the hybrid monohull s.

Due to the lower efficiency of stratospheric airship s motion control, changing the center of gravity position in order to control airship s longitudinal motion was discussed.

A mathematical model of longitudinal motion control system on SWATH is presented and its experimental platform is established in this paper.

Based on a typical ship, this paper establishes a model of longitudinal movement and then discusses three ways of disturbance estimation: central difference, corlored Kalman filter and extended Kalman filter.

The code considers both transverse and longitudinal movements in the accelerators using a used 4 order variable step Runge Kutta method to calculate the beam envelope of the transverse movement, the phase oscillation curve of the longitudinal movement, the energy growth, the energy distribution at the exit, and the longitudinal electric and magnetic field distributions.
