Random good picture Not show

1. A normal distribution has a kurtosis measure of 3, and a leptokurtic distribution occurs when the kurtosis is well over 3.

2. Unfortunately, when skewness and kurtosis are taken into account, this need not be the case.

3. This result supports the authors viewpoint about kurtosis statistical meanings:kurtosis is a kind of measure of population datas degree of outlier.

4. Based on the signal kurtosis, a blind signal extraction algorithm was proposed in over-determined mixtures.

5. Based on maximum kurtosis criteria, a new blind identification and equalization algorithm is designed for linear system.

6. An approach named component analysis based on kurtosis ( CABK ) was used to identify the overlapped peaks.

7. Kurtosis is a classical measure of non-Gaussianity of random variable.

8. First, we introduce systematic skewness and systematic kurtosis into traditional CAPM, making it to be an even generalized model containing higher-moment.

9. Then peak index, kurtosis index, impulsion index and tolerance index of the vibration signal are calculated. These parameters represent the characteristic of failures.

10. The variance law of kurtosis with age is not obvious, kurtosis of stands with low density is bigger than stands with high density, and the value of kurtosis, both of them, tends to 0 at last.

10. Sentencedict.com try its best to collect and create good sentences.

11. This paper proposes a new algorithm of video watermarking based on kurtosis and DCT.

12. I also discuss the potential effect of time-varying skewness and kurtosis on the performance of the model.

13. It is known that usually the degree of sharpness (or flatness) of beam intensity distribution is described by the kurtosis parameter (K parameter).

14. The results indicate that mean grain size, sorting coefficient, skewness and kurtosis are respectively significantly correlative. Their correlation coefficients are depressed in turn.

15. Through theoretical derivation, a new algorithm based on IFFT and time domain randomization for the simulation of non-gaussian random processes with specified PSD, skewness and kurtosis was proposed.

16. This paper puts forward an algorithm based on joint maximization of kurtosis and autocorrelation, and applies it to the separation of fetal electrocardiogram.

17. Then, the amount of the range shift between two echoes is searched by using the modified kurtosis as the alignment measure.

18. Considering the nonlinear and redundant characteristic of the data in real industry process, a nonlinear independent component analysis based on kurtosis is presented.

19. A new blind beamforming algorithm for non-Gaussian signals with arbitrary kurtosis is presented in this paper.

20. This paper proposes an algorithm for Fetal Electrocardiogram (FECG) extraction, which is based on joint maximization of kurtosis and autocorrelation .

21. Based on the characteristic of WM signals, a step by step classification method using high order cumulants and kurtosis of power spectrum as features is proposed.

22. A portfolio selection model with transaction costs under the constraint of higher moments such as skewness and kurtosis was discussed.

23. In this paper, the technique of BSE(Blind Signal Extraction) based on kurtosis is analyzed and it is applied to radar signal sorting.

24. Practically, the application of options implied second moment, implied volatility, is very popular, but the study of implied third moment, skewness, and fourth moment, kurtosis, is seldom.
