Abstract: Abstract An efficient finite-difference frequency-domain modeling of seismic wave propagation relies on the discrete schemes and appropriate solving methods. The average-derivative optimal scheme for the scalar wave modeling is advantageous in terms of the storage… read more here.

Published in 2019 at "International Journal of Computational Methods"

DOI: 10.1142/s0219876218430119

Abstract: In this paper, we present a new and interesting optimal scheme of order eight in a general way for solving nonlinear equations, numerically. The beauty of our scheme is that it is capable of producing… read more here.
