Gap solitons in a spin-orbit-coupled bose-einstein condensate
We report a diversity of stable gap solitons in a spin-orbit-coupled Bose-Einstein condensate subject to a spatially periodic Zeeman field. It is shown that the solitons can be classified by the main physical symmetries ...
On the dynamic behaviour of a nonlinear system weakly connected to a linear single degree-of-freedom system
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 ...
An overview on a nonideal system with three and a half degrees of freedom
The present paper studies a system comprised of two blocks connected by springs and dampers, and a DC motor with limited power supply fixed on a block, characterizing a non-ideal problem. This DC motor exciting the system ...
Velocity Estimation by Using a State Reconstructor for Stabilizing a Two Degree of Freedom Mechanical Manipulator

On Nonlinear Dynamics and Control of A Particular Portal Frame Foundation Model, Excited by a Non-Ideal Motor
The nonlinear dynamic response and a nonlinear control method of a particular portal frame foundation for an unbalanced rotating machine with limited power (non-ideal motor) are examined. Numerical simulations are performed ...
A Comparison of the Effects of Nonlinear Damping on the Free Vibration of a Single-Degree-of-Freedom System
(Asme-amer Soc Mechanical Eng, 2012-04-01)
This article concerns the free vibration of a single-degree-of-freedom (SDOF) system with three types of nonlinear damping. One system considered is where the spring and the damper are connected to the mass so that they ...
