Dynamics of nearly unstable axisymmetric liquid bridges [PDF]
, 2010 The dynamics of a noncylindrical, axisymmetric, marginally unstable liquid bridge between two equal disks is analyzed in the inviscid limit. The resulting model allows for the weakly nonlinear description of both the (first stage of) breakage for ...

The simplest approach to nonlinear oscillators
Results in Physics, 2019 This paper gives the simplest approach to the cubic-quintic Duffing equation (M.S.H. Chowdhury et al., Results in Physics 7(2017): 3962–3967), providing an extremely fast and relatively accurate estimation of the frequency of a nonlinear conservative ...

AIP Advances, 2020 In the present work, a new method for solving a strong nonlinear oscillator equation of the form ẍ + F(x) = 0, where F(−x) = −F(x), is carried out. This method consists of approximating function F(x) by means of a suitable Chebyshev polynomial: F(x) ≈ P(

Journal of Low Frequency Noise, Vibration and Active Control, 2023 In this study, the nonlinear damping oscillations in a complex non-Maxwellian plasma are investigated. For this purpose, the set of fluid equations of the present plasma model is reduced to the Burger-modified Korteweg De Vries equation (BmKdV) equation ...

Chaotic Cipher Using the Duffing Equation
Information Security Journal: A Global Perspective, 2010 We propose a plain files cipher by means of a stream cryptosystem scheme with chaotic addition and a symmetric key. The sequence of numbers used for encryption is generated by a continuous chaotic dynamical system; in particular, we choose the forced Duffing equation since this kind of systems is sensitive to the initial conditions. In a chaotic system,

Stability analysis of a noise-induced Hopf bifurcation [PDF]
, 2003 We study analytically and numerically the noise-induced transition between an absorbing and an oscillatory state in a Duffing oscillator subject to multiplicative, Gaussian white noise.

Semilinear Duffing Equations Crossing Resonance Points
Journal of Differential Equations, 1997 Consider the Duffing equation \[ \ddot x+g(x)= p(t),\tag{\(*\)} \] where \(g,p\in C(\mathbb{R})\), \(q(0)=0\), \(p\) is \(2\pi\)-periodic, \(g\) is Lipschitzian and there exist two constants \(A_0>0\) and \(M_0>0\) such that \(x^{-1}g(x)\geq A_0\) for \(|x|> M_0\).
