Parametric vibrational resonance in a gyroscope driven by dual-frequency forces

open access: yesPhysics Letters, Section A: General, Atomic and Solid State Physics, 2021
We examine and analyze vibrational resonance (VR) in a dual-frequency-driven gyroscope subject to a parametric excitation and an additive periodic forces.

Parametric Resonance in DNA

Bulletin of Mathematical Biology, 2014
We consider a simple mesoscopic model of DNA in which the binding of the RNA polymerase enzyme molecule to the promoter sequence of the DNA is included through a substrate energy term modeling the enzymatic interaction with the DNA strands. We focus on the differential system for solitary waves and derive conditions--in terms of the model parameters ...

Parametric resonance

Computing in Science & Engineering, 1999
Computer simulation experiments are especially good tools for helping students understand basic principles of physics. In this a, I have developed a package of simulation programs called Physics of Oscillations. One of its programs is suited for examining the phenomenon of paramagnetic resonance in a linear system.

Parametric Resonant Control of Chaos

International Journal of Bifurcation and Chaos, 1998
A concise account is given of the early motivations for introducing parametric methods to achieve control of chaos. The heuristic argument that made us think that this kind of method could have been successful is also given. A key study is then reviewed.

An Introduction to Parametric Resonance

2011
In many engineering, physical, electrical, chemical, and biological systems, oscillatory behavior of the dynamic system due to periodic excitation is of great interest. Two kinds of oscillatory responses can be distinguished: forced oscillations and parametric oscillations.

Mode Coupling and Parametric Resonance in Electrostatically Actuated Micromirrors

IEEE transactions on industrial electronics (1982. Print), 2018
The main torsional mode of electrostatically actuated micromirrors is known to be dominated by parametric resonance when the actuation is performed via in-plane comb fingers. Here, we show that, for specific geometrical features of the mirror, parametric

Parametric Resonance of Pipes with Soft and Hard Segments Conveying Pulsating Fluids

International Journal of Structural Stability and Dynamics, 2018
In this paper, the parametric resonance of pipes with soft and hard segments induced by pulsating fluids is investigated. The lowest six natural frequencies and mode shapes of the soft–hard combination pipe simply supported at both ends are obtained by ...
