Modelling of Parametric Resonance for Heaving Buoys with Position-Varying Waterplane Area
Journal of Marine Science and Engineering, 2021 Exploiting parametric resonance may enable increased performance for wave energy converters (WECs). By designing the geometry of a heaving WEC, it is possible to introduce a heave-to-heave Mathieu instability that can trigger parametric resonance.

Modal Behavior of Microcantilevers Arrays with Tunable Electrostatic Coupling
Actuators, 2023 We analyse the spectral content and parametric resonant dynamics of an array of elastically and electrostatically coupled interdigitated micro cantilevers assembled into two identical half-arrays.

Numerical Study of Forced Vibration Suppression by Parametric Anti-Resonance
Archives of Acoustics, 2016 The parametric anti-resonance phenomenon as an active damping tool for suppression of externally excited resonant vibration is numerically studied herein. It is well known fact that the anti-resonance phenomenon, i.e.

Adaptive Properties of a Ferromagnetic Single-Domain Grain in Alternating Magnetic Fields
IEEE Access, 2023 A general self-consistent theory of adaptive properties of a ferromagnetic single-domain grain in alternating magnetic fields is constructed. Thresholds of new family of parametric instabilities of all orders are calculated. It is shown that the level of

Parametric Resonance of Hopf Bifurcation [PDF]
Nonlinear Dynamics, 2005 We investigate the dynamics of a system consisting of a simple, harmonic oscillator with small nonlinearity, small damping and small parametric forcing in the neighborhood of 2:1 resonance. We assume that the unforced system exhibits the birth of a stable limit cycle as the damping changes sign from positive to negative (a supercritical Hopf ...

Parametric resonance for complex fields [PDF]
Physics Letters B, 2000 Recently, there have been studies of parametric resonance decay of oscillating real homogeneous cosmological scalar fields, in both the narrow-band and broad-band case, primarily within the context of inflaton decay and (p)reheating. However, many realistic models of particle cosmology, such as supersymmetric ones, inherently involve complex scalar ...

On the observation of nonclassical excitations in Bose–Einstein condensates
New Journal of Physics, 2016 In the recent experimental and theoretical literature well-established nonclassicality criteria from the field of quantum optics have been directly applied to the case of excitations in matter-waves.

Parametric Resonance of Optically Trapped Aerosols [PDF]
Physical Review Letters, 2007 The Brownian dynamics of an optically trapped water droplet are investigated across the transition from over to under-damped oscillations. The spectrum of position fluctuations evolves from a Lorentzian shape typical of over-damped systems (beads in liquid solvents), to a damped harmonic oscillator spectrum showing a resonance peak. In this later under-
