A semiempirical approach to a viscously damped oscillating sphere
(IOP Publishing, 2005-12)
A simple model of damped harmonic motion is usually presented in undergraduate physics textbooks and straightforwardly applied for a variety of well-known experiments in student laboratories. Results for the decaying ...
Dynamics of damped oscillations: physical pendulum
(2017-10-23)
The frictional force of the physical damped pendulum with the medium is usually assumed proportional to the pendulum velocity. In this work, we investigate how the pendulum motion will be affected when the drag force is ...

The frictional force of the physical damped pendulum with the medium is usually
assumed proportional to the pendulum velocity. In this work, we investigate

Energy exchange between coupled mechanical oscillators: linear regimes
(IOP Publishing, 2018-09)
Nonlinear mechanisms are frequently invoked to explain unexpected observations during processes of energy exchange in mechanical systems. However, whether the same phenomena could be observed in a purely linear system is ...
On the effects of system parameters on the response of a harmonically excited system consisting of weakly coupled nonlinear and linear oscillators
(Academic Press Ltd Elsevier B.V. Ltd, 2011-08-01)
This paper discusses the dynamic behaviour of a nonlinear two degree-of-freedom system consisting of a harmonically excited linear oscillator weakly connected to a nonlinear attachment having linear and cubic restoring ...

A general formulation for the magnetic oscillations in two dimensional systems
(Springer, 2020-05-18)
We develop a general formalism for the magnetic oscillations (MO) in two dimensional (2D) systems. We consider general 2D Landau levels, which may depend on other variable or indices, besides the perpendicular magnetic ...
On twin peak quasi-periodic oscillations resulting from the interaction between discoseismic modes and turbulence in accretion discs around black holes
(2020)
Given the peculiar and (in spite of many efforts) unexplained quasi-periodic oscillation (QPO) twin peak phenomena in accretion disc psd observations, the present
exploratory analytical article tries to inquire deeper ...
EXPLOITING THE TRANSIENT RESPONSE OF A SINGLE DEGREE-OF-FREEDOM OSCILLATOR FOR THE PURPOSE OF ENERGY HARVESTING
(Int Inst Acoustics & Vibration, 2015-01-01)
Vibration-based energy harvesters have been intensively studied recently because of the need to power wireless devices or to augment the use of batteries. When time-unlimited harmonic excitation is provided to a single ...
