Analysis of a New Fractional Model for Damped Bergers’ Equation
Open Physics, 2017 In this article, we present a fractional model of the damped Bergers’ equation associated with the Caputo-Fabrizio fractional derivative. The numerical solution is derived by using the concept of an iterative method.

Structure of traveling wave solutions for some nonlinear models via modified mathematical method
Open Physics, 2018 We have employed the exp(-φ(ξ))-expansion method to derive traveling waves solutions of breaking solition (BS), Zakharov-Kuznetsov-Burgers (ZKB), Ablowitz-Kaup-Newell-Segur (AKNS) water wave, Unstable nonlinear Schrödinger (UNLS) and Dodd-Bullough ...
