Comparison of alternative improved perturbative methods for nonlinear oscillations
We discuss and compare two alternative perturbation approaches for the calculation of the period of nonlinear systems based on the Lindstedt–Poincaré technique. As illustrative examples we choose one–dimensional anharmonic oscillators and the Van der Pol equation. Our results show that each approach is better for just one type of model considered here.
متن کاملTopological Methods for Nonlinear Oscillations
Introduction Periodic phenomena play a pervasive role in natural and in man-made systems. They are exhibited, for example, in simple mathematical models of the solar system and in the observed circadian rhythms by which basic biological functions are regulated. Electronic devices producing stable periodic signals underlie both the electrification of the world and wireless communications. My int...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
