Optimization of scan delay time for multi-slice spiral CT angiography of portal venous in liver cirrhosis;

The study on delay time of EEG sequence;

Investigation of several delay times in operation process of multi-cycle pulse detonation engine;

The delayed time can be adjusted automatically.

By choose appropriate delayed time and embed dimension,we get a relevant associated dimension,just as the attract dimension.

The delayed time may not be an integer multiple of the period of the inherent unstable orbit in the chaotic attractor.

The paper mainly introduces the process of estimating the reservoir permeability using the frecquency offset and time lag of Stoneley wave.

The choice of important parameter time lag L was studied during phase space reconstruction.

Based on the time-delayed Logistic model,taking the influences of the fluctuating environmental factors on the tumor cell growth into account,an additive noise and a multiplicative noise are introduced into the model and a stochastic delayed differential equation is obtained to describe the tumor cell growth process.

The results are conducted to demonstrate that wavelet transform analysis computes time-delay more accurately when Signal-to-Noise is little.

This paper analyzed the problem of time-delay in the passive acoustic detection network, and presented an orientation algorithm which could be applied to resolve this problem in the above system.
