Bulletin of the Belgian Mathematical Society - Simon Stevin, 2007 The authors study an interesting problem involving periodic solutions having a symmetry induced by an orthogonal matrix \(A\) for which there is an integer \(p\) such that \(A^p\) is the identity. More precisely, given \(T>0\), they look for solutions \(x\) satisfying the relation \(x(t+T)=A x(t)\), for every \(t\). These solutions are \(pT\)-periodic.

Beam-beam amplitude detuning with forced oscillations
Physical Review Accelerators and Beams, 2017 Recently, relations were established between the coefficients of free and forced amplitude detuning polynomial expansions. The forced oscillations were considered only in a single plane.

On oscillations in the Social Force Model [PDF]
Physica A: Statistical Mechanics and its Applications, 2015 The Social Force Model is one of the most prominent models of pedestrian dynamics. As such naturally much discussion and criticism has spawned around it, some of which concerns the existence of oscillations in the movement of pedestrians. This contribution is investigating under which circumstances, parameter choices, and model variants oscillations do

General Forced Oscillations in a Real Power Grid Integrated with Large Scale Wind Power
Energies, 2016 According to the monitoring of the wide area measurement system, inter-area oscillations happen more and more frequently in a real power grid of China, which are close to the forced oscillation.

On the Countering of Free Vibrations by Forcing: Part II—Damped Oscillations and Decaying Forcing
Applied Mechanics, 2023 The present two-part paper concerns the active vibration suppression for the simplest damped continuous system, namely the transverse oscillations of an elastic string, with constant tension and mass density per unit length and friction force ...

Forced oscillations of beams on elastic bearings
Electronic Journal of Qualitative Theory of Differential Equations, 2004 We study the existence of weak periodic solutions for certain damped and forced linear beam equations resting on semi-linear elastic bearings. Conditions for the periodic forcing term and semi-linear elastic bearings are derived which ensure either the ...

Applied Mechanics, 2022 The question addressed is whether the free oscillations of a continuous system can be suppressed, or at least the total energy reduced, by applying external forces, using as example the linear undamped transverse oscillations of a uniform elastic string.
