Nontrivial solutions for a mixed boundary problem for Schrödinger equations with an external magnetic field
(Juliusz Schauder Centre for Nonlinear StudiesTorun, 2015)
We study the existence of solutions for a class of nonlinear Schrödinger equations involving a magnetic field with mixed Dirichlet-Neumann boundary conditions. We use Lusternik-Shnirelman category and the Morse theory to ...
Variational inequality for a nonlinear model of the oscillations of beams
(Nonlinear Analysis: Theory, Methods & Applications, 2019)
Critical evaluation of FBD, pq and CPT current decompositions for four-wire circuits
(2009-12-01)
This paper investigates the major similarities and discrepancies of three important current decompositions proposed for the interpretation of unbalanced and/or non linear three-phase four-wire circuits. The considered ...

Effects of combined hardening and free-play nonlinearities on the response of a typical aeroelastic section
(2016-03-01)
This paper presents an investigation about the dynamic response of a three-degree of freedom airfoil with hardening nonlinearity in the pitching stiffness and free-play nonlinearity in the control surface stiffness using ...
Melnikov analysis in nonsmooth differential systems with nonlinear switching manifold
(2019-09-05)
We study the family of piecewise linear differential systems in the plane with two pieces separated by a cubic curve. Our main result is that 7 is a lower bound for the Hilbert number of this family. In order to get our ...
On a nonlinear and chaotic non-ideal vibrating system with shape memory alloy (SMA)
(Polish Soc Theoretical & Applied Mechanics, 2008-01-01)
In this paper, we present nonlinear dynamic behaviour of a system which consists of a mass connected to a rigid support by a shape memory alloy (SMA) element and a damper. In order to disturb the system, a DC motor with ...
