Resonances of the SD oscillator due to the discontinuous phase

open access: yes, 2011
Resonance phenomena of a harmonically excited system with mul-tiple potential well play an important role in nonlinear dynamics research.In this paper, we investigate the resonant behaviours of a discontinuous dynamical system with double well potential ...

Some fixed point theorems for discontinuous mappings [PDF]

open access: yes
This paper provides a fixed point theorem à la Schauder, where the mappings considered are possibly discontinuous. Our main result generalizes and unifies several well-known results.Schauder fixed point theorem, Brouwer fixed point theorem, discontinuity.

On abolishing symmetry requirements in the formulation of a five-level selective harmonic elimination pulse-width modulation technique [PDF]

open access: yes, 2006
Selective harmonic elimination pulse width modulation (SHE-PWM) techniques offer a tight control of the harmonic spectrum of a given voltage waveform generated by a power electronic converter along with a low number of switching transitions.

An optimal order interior penalty discontinuous Galerkin discretization of the compressible Navier-Stokes equations [PDF]

open access: yes, 2008
In this article we propose a new symmetric version of the interior penalty discontinuous Galerkin finite element method for the numerical approximation of the compressible Navier-Stokes equations.

Equilibria Existence in Regular Discontinuous Games [PDF]

open access: yes
Many conditions have been introduced to weaken the continuity re- quirements for equilibrium existence in games. We introduce a new con- dition, called regularity, that is simple and easy to verify.

Rellich-type Discrete Compactness for Some Discontinuous Galerkin FEM [PDF]

open access: yes
We deduce discrete compactness of Rellich type for some discontinuous Galerkin finite element methods (DGFEM) including hybrid ones, under fairly general settings on the triangulations and the finite element spaces.
