Non-parametric identification of a non-linear buckled beam using discrete-time Volterra Series
(2014-01-01)
The consideration of nonlinearities in mechanical structures is a question of high importance because several common features as joints, large displacements and backlash may give rise to these kinds of phenomena. However, ...
Influence of modal loss on quantum state generation via cross-Kerr nonlinearity
(Amer Physical SocCollege PkEUA, 2009)
A semilinear heat equation with a localized nonlinear source and non-continuous initial data
(Wiley-blackwellMaldenEUA, 2011)
The role of constant vorticity on weakly nonlinear surface gravity waves
(2021-04-01)
This manuscript describes the derivation of systems of equations for weakly nonlinear gravity waves in shallow water in the presence of constant vorticity. The derivation is based on a multi-layer generalization of the ...
Weak signal enhancement by nonlinear resonance control in a forced nano-electromechanical resonator
(Nature, 2020)
Driven non-linear resonators can display sharp resonances or even multistable behaviours amenable to induce strong enhancements of weak signals. Such enhancements can make use of the phenomenon of vibrational resonance, ...
The sub-supersolution method for weak solutions

On the dynamic behaviour of a nonlinear system weakly connected to a linear single degree-of-freedom system
(2011-12-01)
This paper discusses the dynamic behaviour of a nonlinear two degree-of-freedom system consisting of a harmonically excited linear oscillator weakly connected to a nonlinear attachment that behaves as a hardening Duffing ...

Vacuum fluctuations in the presence of nonlinear boundary conditions
(American Physical Society, 2015-12)
We consider a system consisting of a quantum, massless, real scalar field, in the presence of nonlinear mirrors: infinite parallel planes, upon which the field satisfies nonlinear boundary conditions. These may appear, for ...
