An adjoint-based hybrid computational method for crosswell seismic inversion
Found in: Computing in Science & Engineering
By Danping Cao,Wenyuan Liao
Issue Date:February 2014
pp. 1
The waveform tomography, or full waveform inversion (FWI), is in general better than the ray tomography, however a reliable initial model is usually required to ensure the success. In this work we designed a cascade-like hybrid tomography technology to sol...
A New Method for Solving Convection-Diffusion Equations
Found in: Computational Science and Engineering - Workshops, IEEE International Conference on
By Wenyuan Liao, Jianping Zhu
Issue Date:July 2008
pp. 107-114
When solving convection-diffusion equations using the finite difference schemes, the convection term is usually discretized by the upwind schemes to avoid oscillations. Amethod to eliminate the convection term from convection-diffusion equations is present...
