Demiray, H. (2012). A note on the amplitude modulation of symmetric regularized long-wave equation with quartic nonlinearity. Journal of Engineering Mathematics, 77(1), 181-186. doi:10.1007/s10665-012-9538-0Özet
We study the amplitude modulation of a symmetric regularized long-wave equation with quartic nonlinearity through the use of the reductive perturbation method by introducing a new set of slow variables. The nonlinear Schrodinger (NLS) equation with seventh order nonlinearity is obtained as the evolution equation for the lowest order term in the perturbation expansion. It is also shown that the NLS equation with seventh order nonlinearity assumes an envelope type of solitary wave solution.

Nonlinear waves in a stenosed elastic tube filled with viscous fluid: Forced perturbed korteweg-de vries equation
Tay, Kim Gaik; Demiray, Hilmi; Tiong, Ong Chee (Springer Science and Business Media, LLC, 2008)In the present work, treating the artery as a prestressed thin-walled and long circularly cylindrical elastic tube with a mild symmetrical stenosis and the blood as an incompressible Newtonian fluid, we have studied the ... -
Head-on-collision of nonlinear waves in a fluid of variable viscosity contained in an elastic tube
Demiray, Hilmi (Pergamon-Elsevier Science Ltd, 2009-08-30)In this work, treating the arteries as a thin walled, prestressed elastic tube and the blood as an incompressible viscous fluid of variable viscosity, we have studied the interactions of two nonlinear waves, in the long ... -
Reducing a generalized Davey-Stewartson system to a non-local nonlinear Schrodinger equation
Eden, Osman Alp; Erbay, Saadet; Hacınlıyan, Irma (Pergamon-Elsevier Science Ltd, 2009-07-30)In the present study, we consider a generalized (2 + 1) Davey-Stewartson (GDS) system consisting of a nonlinear Schrodinger (NLS) type equation for the complex amplitude of a short wave and two asymmetrically coupled linear ...
