In this paper, a stochastic probability model based on the fractal theory for estimating lightning shielding performance of UHV transmission lines is introduced. This model takes both the deterministic factors and stochastic factors of the lightning process into consideration. Some parameters related to the model are discussed according to features of lightning process and adjusted by comparison with...
Dozens of high level representations of time series have been introduced for data mining in the literature. Traditional dimension reduction methods about similarity query introduce the smoothness to data series in some degree that the important features of time series about non-linearity and fractal are destroyed. In this paper a high-precision approach based on fractal theory and R/S analysis are...
