Trans-scale relationship analysis between the pore structure and macro parameters of backfill and slurry [PDF]
Royal Society Open Science, 2019 The characteristics of the porous structure of backfill are directly related to the macro parameters of the flowability of the filling slurry and the mechanical features of the backfill, which are fundamental to the study of multiscale mechanics of ...

Fractal Analytical Approach of Urban Form Based on Spatial Correlation Function [PDF]
Chaos, Solitons & Fractals, 2013, 49: 47-60, 2012 Urban form has been empirically demonstrated to be of scaling invariance and can be described with fractal geometry. However, the rational range of fractal dimension value and the relationships between various fractal indicators of cities are not yet revealed in theory. By mathematical deduction and transformation (e.g.

Fractal Modeling and Fractal Dimension Description of Urban Morphology [PDF]
Entropy, 2020,22: 961, 2018 The conventional mathematical methods are based on characteristic length, while urban form has no characteristic length in many aspects. Urban area is a measure of scale dependence, which indicates the scale-free distribution of urban patterns. Thus, the urban description based on characteristic lengths should be replaced by urban characterization ...
