Comparing of the HAM with the HPM in finding the natural frequency of a nonlinear oscillating system
Frequency Nonlinear oscillation Series solutions
2010/9/13
In this article, we use an efficient analytical method called homotopy analysis method (HAM) to derive the frequency of a nonlinear oscillating system. Unlike the perturbation method, the HAM does not...
Explicit approximate solution for finding the natural frequency of the motion of pendulum by using the HAM
Frequency Nonlinear oscillation Series solutions
2010/9/13
In this work, we use a powerful analytical method called homotopy analysis method (HAM) to derive the frequency of a nonlinear oscillating system. Unlike the perturbation method, the HAM does not requ...
Estimation of Vs profile using its natural frequency and Rayleigh-wave dispersion characteristics
Estimation Vs profile natural frequency Rayleigh-wave dispersion characteristics
2010/1/27
The evaluation of the natural frequency of random Vs profiles before analyzing the fundamental Rayleigh-wave dispersion characteristics is proposed in this paper. The inclusion of this parameter optim...
