Application of He's variational iteration method to the fifth-order boundary value problems

Application of variational iteration method for solving singular two point boundary value problems

In this paper, He's highly prolic variational iteration method is applied ef-fectively for showing the existence, uniqueness and solving a class of singularsecond order two point boundary value problems. The process of nding solu-tion involves generation of a sequence of appropriate and approximate iterativesolution function equally likely to converge to the exact solution of the givenproblem w...

Variational Iteration Method for Fifth-Order Boundary Value Problems Using He's Polynomials

We apply the variational iteration method using He’s polynomials VIMHP for solving the fifthorder boundary value problems. The proposedmethod is an elegant combination of variational iteration and the homotopy perturbationmethods and is mainly due to Ghorbani 2007 . The suggested algorithm is quite efficient and is practically well suited for use in these problems. The proposed iterative scheme...

Variational Iteration Method for Free Vibration Analysis of a Timoshenko Beam under Various Boundary Conditions

In this paper, a relatively new method, namely variational iteration method (VIM), is developed for free vibration analysis of a Timoshenko beam with different boundary conditions. In the VIM, an appropriate Lagrange multiplier is first chosen according to order of the governing differential equation of the boundary value problem, and then an iteration process is used till the desired accuracy ...

The variational iteration method for a class of tenth-order boundary value differential equations

Application of variational iteration method for solving singular two point boundary value problem

DEA methodology allows DMUs to select the weights freely, so in the optimalsolution we may see many zeros in the optimal weight. to overcome this prob-lem, there are some methods, but they are not suitable for evaluating DMUswith fuzzy data. In this paper, we propose a new method for solving fuzzyDEA models with restricted multipliers with less computation, and comparethis method with Liu''''''...
