Nonlinear resonances phenomena in a modified Josephson junction model
(2020-12-01)
In this paper, the equivalent circuit of the non-autonomous Josephson junction (JJ) is presented and the effect of the proper frequency on the phase φ is studied. We also study nonlinear resonance phenomena in the oscillations ...
Wave reflection at the end of a waveguide supported by a nonlinear spring
(European Assoc Structural Dynamics, 2014-01-01)
The way in which a nonlinear spring affects the reflection coefficients at the end of a rod and a beam is investigated in this paper. The specific type of nonlinearity considered is of the hardening and softening Duffing-type, ...

On grazing bifurcations in an aeroelastic system with multi-segmented nonlinearity in the pitch degree of freedom
(2014-01-01)
A nonlinear characterization based on modern methods of nonlinear dynamics is performed to identify the effects of a multisegmented nonlinearity on the response of an aeroelastic system. This system consists of a plunging ...

Influence of nonlinear effects on the acoustic levitation of small spheres
(IEEEChicago, Illinois, 2014-09-03)
This paper presents the nonlinear characterization of a single-axis acoustic levitator and the analysis of the influence of nonlinear effects on the acoustic levitation of small spheres. First, the nonlinear characterization ...
On the Filtering Problem for Continuous-Time Markov Jump Linear Systems with no Observation of the Markov Chain
(LAVOISIER, 2011)
We consider in this paper the optimal stationary dynamic linear filtering problem for continuous-time linear systems subject to Markovian jumps in the parameters (LSMJP) and additive noise (Wiener process). It is assumed ...
On the contact stiffness and nonlinear vibration of an elastic body with a rough surface in contact with a rigid flat surface
(Elsevier B.V., 2015-01-01)
The surface topography of engineering rough surfaces has an enormous influence on contact mechanics of the interface and further the dynamics of the contact system. In this paper, the force-deflection characteristic and ...
