Dynamic estimate of seismic danger based on multifractal properties of low-frequency seismic noise

Lyubushin, A. - In: Natural Hazards 70 (2014) 1, pp. 471-483

A new method of dynamic estimate of seismic danger is presented which is based on estimating multifractal properties of low-frequency seismic noise. The efficiency of the method is illustrated by the analysis of seismic noise from broadband seismic network F-net in Japan. The analysis of...

Modulation of heart disease information to the 12-lead ECG multifractal distribution

Wang, Jun; Ning, Xinbao; Chen, Ying - In: Physica A: Statistical Mechanics and its Applications 325 (2003) 3, pp. 485-491

In this paper, a new viewpoint is proposed: the synchronous 12-lead ECG multifractal singularity spectrum distribution … is modulated by the heart disease information. There is a well-regulated multifractal singularity spectrum distribution … among different leads. We consider that the mean value of the area of human 12-lead ECG multifractal singularity spectrum is …
