Making use of the radar ′s radial velocity withdraw characteristic point of the unsteady trajectory,models of the data processing are created by using cubic splines,and resolve the problem of the data process of not steady trajectory.

Based on Andrew,we put forward a nonstationary robust and general long memory testing approach.

Based on the precondition of ignoring unload impulsion and adaptability of hydrokinetic parameters to torpedo equation at low speed,the uncontrolled trajectory of dummy torpedo is simulated and analyzed.

Application of Multidimensional Non-stationary Time Series on Fault Diagnosis of Spindle;

Simulation of non-stationary spatial correlative time histories of multi-point ground motion;

New method to improve identification ability of neural networks in non-stationary environment;

Study of nonstationary stochastic groundwater flow modelling;

The Sample Path Optimality for Nonstationary MDP with Average Criterion;

Study on Nonstationary Ride Dynamics and Control of Vehicle;

For the nonstationarity and spectrum chaos of the bearing vibration signal,threshold de-noising based on wavelet decomposition was put forward.

Base on that,the application of wavelet transformation in fault diagnosis to analyse nonstationarity of roller bearing vibration signals with Daubieches wavelet is introduced.
