In this paper, an inverse-free dynamical system with fixed-time convergence is presented to solve the of absolute value equations (AVEs). Under a mild condition, it proved that solution proposed converges AVEs. Moreover, in contrast existing \cite{chen2021}, conservative settling-time method given. Numerical simulations illustrate effectiveness new method.

This study presents a workflow to predict the upscaled absolute permeability of rock core direct from CT images whose resolution is not sufficient allow pore-scale computation. exploits deep learning technique with data raw rocks and their corresponding value obtained by performing flow simulation on high-resolution images. The map much larger region in predicted trained neural network. Finally...
