Effects of time-periodic linear coupling on two-component Bose-Einstein condensates in two dimensions
(Elsevier B.V., 2008-03-03)
We examine two-component Gross-Pitaevskii equations with nonlinear and linear couplings, assuming self-attraction in one species and self-repulsion in the other, while the nonlinear inter-species coupling is also repulsive. ...

Some remarks on bifurcation analysis of a nonlinear vibrating system excited by a shape memory alloy material (SMA)
(2011-10-01)
In this paper, the dynamical response of a coupled oscillator is investigated, taking in consideration the nonlinear behavior of a SMA spring coupling the two oscillators. Due to the nonlinear coupling terms, the system ...

Aeroelastic energy harvesting behaviour with combined nonlinear stiffness and nonlinear electromechanical coupling
(Universidade Estadual Paulista (Unesp), 2020-07-31)
Energy harvesting é uma tecnologia promissora para a obtenção de energia renovável, e tem chamado muita atenção, ultimamente. Seu objetivo é extrair a energia presente no ambiente e transferi-la para os diversos dispositivos ...
Magnetic corrections to the boson self-coupling and boson-fermion coupling in the linear sigma model with quarks
(2020)
We compute the magnetic-field-induced modifications to the boson self-coupling and the boson-fermion coupling, in the static limit, using an effective model of QCD, the linear sigma model with quarks. The former is computed ...
Coupled axial/torsional vibrations of drill-strings by means of non-linear model
(Pergamon-Elsevier Science Ltd, 2007-07)
In the present work a geometrically non-linear model is presented to study the coupling of axial and torsional vibrations on a drill-string, which is described as a vertical slender beam under axial rotation. It is known ...
On exact boundary controllability for linearly coupled wave equations
(Academic Press Inc. Elsevier B.V., 2011-09-15)
In this paper we study exact boundary controllability for a system of two linear wave equations coupled by lower order terms. We obtain square integrable control of Neuman type for initial state with finite energy, in ...
