Characterization and Generation of 3D Realistic Geological Particles with Metaball Descriptor based on X-Ray Computed Tomography

no code implementations5 Feb 2023 Yifeng Zhao, Xiangbo Gao, Pei Zhang, Liang Lei, S. A. Galindo-Torres, Stan Z. Li

This algorithm can capture the main contour of parental particles with a series of non-overlapping spheres and refine surface-texture details through gradient search.

A Data-driven feature selection and machine-learning model benchmark for the prediction of longitudinal dispersion coefficient

no code implementations16 Jul 2021 Yifeng Zhao, Pei Zhang, S. A. Galindo-Torres, Stan Z. Li

Then, a global optimal feature set (the channel width, the flow velocity, the channel slope and the cross sectional area) was proposed through numerical comparison of the distilled local optimums in performance with representative ML models.
