Investigation on thawing conditions of frozen water-richen aluminum hydroxide sludge;

To obtain the reason why floccules appear while frozen platelet being thawed,thd authors research several possible related factors.

Study on influence of rock slope failures by freezing and thawing action;

Based on the theories of lubrication approximations and Nusselt liquid film flowing,a model describing close contact melting of phase change solid around a hot sphere is developed by applying a more stringent energy balance relation at the two phase interface.

Under the linear minimum variance optimal information fusion criterion weighted by scalars for components,a self-tuning component decoupled fusion Kalman filter is presented,and it is proved by the dynamic error system analysis(DESA) method that it converges to the optimal component decoupled fusion steady-state Kalman filter,so that it has the asymptotic optimality.
