Extracting and analyzing sub-signals in heart period signal by using wavelet transform;

The electrocardiogram (ECG) similar II l ead was recorded for 2 min, in order to analyze the spectrum parameters of heart period signal (HPS).

Study on a new method for high-speed data acquisition of periodic signal;

Waveform design and spectral analysis in direct digital synthesizing of periodic signals;

Study on sampling non-synchronism for periodic signal;

According to the queue length waiting in each intersection,both the signal cycle and the split of every intersection were given out.

A method of computing the signal cycle for the coordinated signal control scheme is i.

The queuing states in the green end were taken as objective,the dynamic signal timing at single-point intersection under the control of two-phase signal was studied,a queuing model was built according to the queuing and discharging process,and the effects of signal cycle,split and arrival ratio on the queuing states were analysed.

Reconstruction of periodic signals based on non-uniformity synchronous sampling;

Application of genetic algorithm in Fourier transform of periodic signals;

Detection methods research of frequency domain based on periodic signals;

This paper analyzes the factors which affect the capacity and level of service of the single signalized intersection , reveals the pattern how the capacity and delay change with the changes of the cycle , draw a reasonable extend of a optimum cycle , put forward the traffic management measures when the intersection is saturated or oversaturated .

Through changing some parameters such as type,frequency,amplitude,offset,and so on,it can get the amplitude eigenvalue that corresponding with the cycle signal and the stochastic signal.

To eliminating the noise in signal and reconstructing signal accurately,a cycle signal analysis based on the PRONY model has been proposed.
