Interaction of pulses in the nonlinear Schrödinger model
(2003-05-01)
A study was conducted on the interaction of two pulses in the nonlinear Schrodinger (NLS) model. The presence of different scenarios of the behavior depending on the initial parameters of the pulses, such as the pulse ...
A Time-domain Harmonic Power-Flow Analysis in Electrical Energy Distribution Networks, Using Norton Models for Non-linear Loading
(Ieee, 2014-01-01)
The purpose of this paper is to present the application of a three-phase harmonic propagation analysis time-domain tool, using the Norton model to approach the modeling of non-linear loads, making the harmonics currents ...
Nonlinear reduced-order modeling and bifurcation analysis of whirl flutter in a rotor-nacelle system
(2020-01-01)
Whirl flutter is an aeroelastic instability that can be affected by structural or/and aerodynamic nonlinearities. This instability may lead to potentially dangerous behaviors. In this study, a nonlinear reduced-order model ...
Array of Bose-Einstein condensates under time-periodic Feshbach-resonance management
(2003-11-01)
The investigation of the dynamics of a discrete soliton in an array of Bose-Einstein condensates under the action of a periodically time-modulated atomic scattering length [Feshbach-resonance management (FRM)] was discussed. ...

An analog model for quantum lightcone fluctuations in nonlinear optics
(2013-02-01)
We propose an analog model for quantum gravity effects using nonlinear dielectrics. Fluctuations of the spacetime lightcone are expected in quantum gravity, leading to variations in the flight times of pulses. This effect ...
Application of Volterra series in nonlinear mechanical system identification and in structural health monitoring problems
(Universidade Estadual Paulista (Unesp), 2016-03-04)
Nonlinear structures are frequent in structural dynamics, specially considering screwed components, with joints, clearance or flexible components presenting large displacements. In this sense the monitoring of systems based ...
CP1|1 nonlinear sigma model vs strong electron correlations
(Elsevier Inc., 2020)
On the detection of a nonlinear damage in an uncertain nonlinear beam using stochastic Volterra series
(2020-07-01)
In the present work, two issues that can complicate a damage detection process are considered: the uncertainties and the intrinsically nonlinear behavior. To deal with these issues, a stochastic version of the Volterra ...
