First, the false peak of Burg Spectrum estimation is introduced. In this paper, a new method of eliminating false peak based on Empirical Mode Decomposition is proposed. Secondly, this new method is used in the Line spectrum analysis of ship radiated noise simulation signal. Compared with traditional Linear Spectrum analysis, it is a better method for signal analysis and processing.
Taking daily data of Shanghai metro passenger flow as research object, an index of `n-day' average passenger flow volume is introduced to construct “time-series”,the change rate of daily volume against `7-day' average was used for analyzing the characteristics of working day passenger flow.On this basis, the research constructs ARIMA forecast model for Daily Passenger Flow of Shanghai Metro is constructed...
Effective customer satisfaction evaluation is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we establish the power customer satisfaction evaluation index system based on previous studies. Then we prove the validity of this method through field investigations by using AMOS. Finally, path coefficient analysis is conducted to get key factors to improve...
