查询词典 iterated kernel

By using the steepest descent rule, the estimated second-truncated Volterra kernel parameters can be obtained after the object function converged. Based on the above results, the geometric assignment of kernel parameter vector corresponding to particular fault or normal operation, which is lies in a fixed and fault-specified direction in the parameter space, was used to fault diagnosis and Fault Isolation.

During the calculation the results got by quintic spline kernel was the best so it was chosen as the proper kernel for the SPH simulation. By comparison of the simulation results got by SPH and finite volume method, it was proved that the buffer cells method proposed in the SPH simulation to implement the Dirichlet boundary conditions was accurate, and this is of great importance for the simulation of flows pass a pipe. At last, the SPH method was improved to simulate the liquid-solid two phase flows and the results show that this method was appropriate for the simulation of flows containing viscous fluid and macroscopic solid components. Now the two methods are both able to predict the continuum flows and rarefied flows severally, but the hybrid program still has some aspects to be improved.
