A. Noor et al. [7] analyze a technique by combining the variational iteration method and the homotopy perturbation method which is called the variational homotopy perturbation method (VHPM) for solving higher dimensional initial boundary value problems. In this paper, we consider the VHPM to obtain exact solution to Gas Dynamics equation.
Variational iteration method has been favourably applied to various kinds of nonlinear problems. The main property of the method is in its flexibility and ability to solve nonlinear equations accurately and conveniently. In this paper recent trends and developments in the use of the method are reviewed. Major applications to nonlinear wave equation, nonlinear fractional differential equations, ...
در این پایان نامه، تحلیل ارتعاشات آزاد غیرخطی نانولوله های کربنی دوجداره در بستر الاستیک وینکلر با در نظر گرفتن نیروی واندروالس غیرخطی بین لایه ای با استفاده از مدل تیر اویلر ـ برنولی غیرموضعی بررسی شده است. نیروی واندروالس غیرخطی بین لایه ای با تابعی غیرخطی بر حسب جابجایی های جداره داخلی و خارجی مدل شده طوری که اثر تغییرات فاصله بین دو جداره در هنگام نوسان نانولوله در نظر گرفته شده باشد. معادل...
in this paper, the multistage variational iteration method is implemented to solve a general form of the system of first-order differential equations. the convergence of the proposed method is given. to illustrate the proposed method, it is applied to a model for hiv infection of cd4+ t cells and the numerical results are compared with those of a recently proposed method.
in this paper, first a new homotopy perturbation method for solving a fractional order nonlinear telegraph equation is introduced. by applying the proposed method, the nonlinear equation is translated to linear equations for per iteration of homotopy perturbation method. then, the obtained problems are solved with separation method. in the examples, it is illustrated that the exact solution is ...
