Parametric resonance brain model [PDF]
The paper introduces a parametric resonance model for characterizing some features of the brain’s electrical activity. This activity is assumed to be a fundamental aspect of brain functionality underpinning functions from basic sensory processing to ...

Quantum parametric resonance [PDF]
The quantum mechanical equivalent of parametric resonance is studied. A simple model of a periodically kicked harmonic oscillator is introduced which can be solved exactly.

Opto-thermally excited multimode parametric resonance in graphene membranes [PDF]
In the field of nanomechanics, parametric excitations are of interest since they can greatly enhance sensing capabilities and eliminate cross-talk. Above a certain threshold of the parametric pump, the mechanical resonator can be brought into parametric ...

Roton Parametric Resonance [PDF]
Parametric excitation of rotons by oscillating electric field exhibits a narrow resonance at the roton minimum frequency. The resonance width is in good agreement with experimental results on the microwave absorption in superfluid helium.Comment: 5 pages,

Parametric Resonance For Complex Fields [PDF]
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.

Cosmological imprints of string axions in plateau [PDF]
We initiate a study on various cosmological imprints of string axions whose scalar potentials have plateau regions. In such cases, we show that a delayed onset of oscillation rather generically leads to a parametric resonance instability.

Parametric Feedback Resonance in Chaotic Systems [PDF]
If one changes the control parameter of a chaotic system proportionally to the distance between an arbitrary point on the strange attractor and the actual trajectory, the lifetime τ of the most stable unstable periodic orbit in the vicinity of this point

Parametric fluctuations of underground and elevated oil pipeline
Based on the use of the assumptions of the theory of closed cylindrical shells by Vasiliy Z. Vlasov, the authors suggested an analytical method for the study of dynamic instability of pipelines.

Analytical solutions of a particular Hill's differential system [PDF]
Consider a second order differential linear periodic equation. This equation is recast as a first-order homogeneous Hill’s system. For this system we obtain analytical solutions in explicit form. The first solution is a periodic function.
