Improved Image Analysis Method to Evaluate Tracking Property under Successive Flashover Based on Fractal Theory

open access: yesEnergies, 2021
Successive flashover would result in carbonized tracking on insulator surface and cause deterioration to the insulation. Thus, investigation of the tracking can be beneficial in understanding flashover characteristics during long-term operation.

Box dimension of the border of Kingdom of Saudi Arabia

open access: yesHeliyon, 2023
Fractal dimension unlike topological dimension is (usually) a non-integer number which measures complexity, roughness, or irregularity of an object with respect to the space in which the set lies.
