NMR and SEM fractal dimensions explore shale pore structure taking the Upper Paleozoic shale in Ordos Basin as an example.

open access: yesPLoS ONE
In this paper, the fractal dimension is calculated by extracting pore parameters from SEM images and NMR experimental data, the pore structure heterogeneity in plane and space is comprehensively discussed, and the relationship between the fractal ...

Fractal dimension algorithms and their application to time series associated with natural phenomena

open access: yes, 2013
Chaotic invariants like the fractal dimensions are used to characterize non-linear time series. The fractal dimension is an important characteristic of systems, because it contains information about their geometrical structure at multiple scales. In this

A study on the fractal characteristics of displacement time-series during the evolution of landslides

open access: yesGeomatics, Natural Hazards & Risk, 2016
Landslides are one of the major natural disasters that are frequently occurring in southwestern China. The main objective of this study is to investigate the relationship between failure of landslide and fractal dimension using displacement time-series ...

Fractal dimension analysis of higher-order mode shapes for damage identification of beam structures

open access: yes, 2012
Fractal dimension analysis is an emerging method for vibration-based structural damage identification. An unresolved problem in this method is its incapability of identifying damage by higher-order mode shapes. The natural inflexions of higher-order mode
