An Interface Design for Calculation of Fractal Dimension

Chaos Theory and Applications, 2020
Partially insufficient is the modelling of irregular and complex forms using Euclidean geometry. On the other hand, fractal geometry allows irregular complex forms and structures to be expressed in mathematical terms. While fractal geometry appears to be

Scale invariance of daily runoff time series in agricultural watersheds [PDF]

Hydrology and Earth System Sciences, 2006
Fractal scaling behavior of long-term records of daily runoff time series in 31 sub-watersheds covering a wide range of size were examined using the shifted box-counting method and Hurst rescaled range (R/S) analysis. These sub-watersheds were associated
