The dynamics of the pendulum suspended on the forced Duffing oscillator [PDF]
, 2012 We investigate the dynamics of the pendulum suspended on the forced Duffing oscillator. The detailed bifurcation analysis in two parameter space (amplitude and frequency of excitation) which presents both oscillating and rotating periodic solutions of ...

Effects of mistuning on dynamic behavior of nonlinear cyclic systems with lump masses and cubic nonlinearity [PDF]
, 2016 Mistuning in cyclic symmetric systems increases severely the forced response of system and splits the modes. This paper concerns with nonlinear behavior of mistuned cyclic systems.

Numerical treatment of seismic accelerograms and of inelastic seismic structural responses using harmonic wavelets [PDF]
, 2007 The harmonic wavelet transform is employed to analyze various kinds of nonstationary signals common in aseismic design. The effectiveness of the harmonic wavelets for capturing the temporal evolution of the frequency content of strong ground motions is ...

The contact angle in inviscid fluid mechanics [PDF]
, 2004 We show that in general, the specification of a contact angle condition at the contact line in inviscid fluid motions is incompatible with the classical field equations and boundary conditions generally applicable to them.

Linear non-normal energy amplification of harmonic and stochastic forcing in turbulent channel flow [PDF]
, 2010 The linear response to stochastic and optimal harmonic forcing of small coherent perturbations to the turbulent channel mean flow is computed for Reynolds numbers ranging from Re_tau=500 to Re_tau=20000.

Rayleigh-B\'enard convection with a melting boundary [PDF]
, 2019 We study the evolution of a melting front between the solid and liquid phases of a pure incompressible material where fluid motions are driven by unstable temperature gradients.

The energy–momentum method for the stability of non-holonomic systems [PDF]
, 1997 In this paper we analyze the stability of relative equilibria of nonholonomic systems (that is, mechanical systems with nonintegrable constraints such as rolling constraints).

A statistical mechanical approach for the computation of the climatic response to general forcings [PDF]
, 2010 The climate belongs to the class of non-equilibrium forced and dissipative systems, for which most results of quasi-equilibrium statistical mechanics, including the fluctuation-dissipation theorem, do not apply.
