Dynamical Integrity and Control of Nonlinear Mechanical Oscillators [PDF]

Journal of Vibration and Control, 2008
The dynamical integrity of nonlinear mechanical oscillators is analyzed in a systematic way extending a previous authors' work. The definition of the safe basin, which is a crucial point that entails choosing what is dynamically acceptable, is critically reviewed.

Nambu Quantum Mechanics: A Nonlinear Generalization of Geometric Quantum Mechanics [PDF]

, 2002
We propose a generalization of the standard geometric formulation of quantum mechanics, based on the classical Nambu dynamics of free Euler tops. This extended quantum mechanics has in lieu of the standard exponential time evolution, a nonlinear temporal

The analytical model of unsteady flow of incompressible monodisperse gas suspension with one-dimensional flow geometry

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2021
Background. One of the developing branches of modern fluid and gas mechanics is the mechanics of multiphase and multicomponent media. Experimental research of many dynamics processes of inhomogeneous media is difficult, therefore, mathematical modeling

Kink and breather waves with and without singular solutions to the Zoomeron model

Results in Physics, 2023
The Zoomeron model is applied to various types of solitons arising in fluid mechanics, laser optics, and nonlinear physics. We derive analytical solutions to the mentioned model using the exp(−λ(ς))-expansion, the generalized Kudryashov, and the ...
