An application of modified reductive perturbation method to symmetric regularizedlongwave
(Işık University Press, 20110324)In this work, we extended the application of "the modified reductive perturbation method" to symmetrical regularized long waves with quadratic nonlinearity and obtained various form of KdV equations as the governing ... 
An approximate wave solution for perturbed KDV and dissipative NLS equations: weighted residual method
(Işık University Press, 20190621)In the present work, we modified the conventional "weighted residual method" to some nonlinear evolution equations and tried to obtain the approximate progressive wave solutions for these evolution equations. For the ... 
Asymptotic solutions of love wave propagation in a covered halfspace with inhomogeneous initial stresses G(3)(1)
(Işık University Press, 2015)The dispersive behavior of Love waves in an elastic halfspace substrate covered by an elastic layer under the effect of inhomogeneous initial stresses has been investigated. Classical linearized theory of elastic waves ... 
Contribution of higher order terms to the nonlinear shallow water waves
