Damped Forced Vibration of Some Quasi-Linear Differential Systems

Dey, Pinakee (University of Rajshahi, 2008)

There are many approaches for approximating solutions of nonlinear vibrating problems. The most common methods for constructing approximate analytical solutions to the nonlinear vibrating problems are the perturbation ...
On Some Approximate Solutions of Nonlinear Physical and Biological Problems

Uddin, Md. Alhaz (University of Rajshahi, 2010)

Most of the perturbation methods are developed to find the periodic solutions of nonlinear systems with small nonlinearities, transients are not considered. In 1947, first Russian scientists Krylov and Bogo Liubov introduced ...
On Some New Approximate Solutions of Fourth Order Nonlinear Differential Equations

Akbar, Md. Ali (University of Rajshahi, 2005)

Most of the perturbation methods are developed to find periodic solutions of nonlinear systems; transients are not considered. First Krylov and BogoLiubov introduced a perturbation method to discuss the transients in the ...
