Fractal Image Interpolation: A Tutorial and New Result
Fractal and Fractional, 2019 This paper reviews the implementation of fractal based image interpolation, the associated visual artifacts of the interpolated images, and various techniques, including novel contributions, that alleviate these awkward visual artifacts to achieve ...

Deep Underground Science and Engineering, EarlyView.Fine modeling of a three‐dimensional fracture structure under dynamic loading of coal is carried out. The streamline distribution law of pressure and velocity field in the loading process of the coal specimen is analyzed, the absolute permeability of the coal specimen is calculated, and the feasibility of the pore network model algorithm and finite ...

Deep Underground Science and Engineering, EarlyView.Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Deep Underground Science and Engineering, EarlyView.In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

Deep Underground Science and Engineering, EarlyView.The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...
