Forced Oscillations of Extensible Beams

SIAM Journal on Mathematical Analysis, 1985
The oscillatory behaviour of solutions of the equation \[ \frac{\partial^ 2u}{\partial t^ 2}+\alpha \frac{\partial^ 4u}{\partial x^ 4}-(\beta -\gamma \int^{L}_{0}(\frac{\partial u(\xi,t)}{\partial \xi})^ 2 d\xi)\frac{\partial^ 2u}{\partial x^ 2}+c(x,t,u)=f(x,t) \] ((x,t)\(\in (0,L)\times (0,\infty))\) is studied.

Oscillations of a forced asymmetric oscillator at resonance

Nonlinearity, 2000
The equation \(x''+\mu x^+-\nu x^-= f(x)+ g(x)+ e(t)\) with \(x^+= \max[x, 0]\); \(x^-= \max[- x,0]\) (this means an asymmetric oscillator, also called ``jumping nonlinearity'') is considered in a situation of resonance for the period \(2\pi\), i.e. when \((\mu+1)/\nu= 2/n\) for some integer \(n\).

Analysis of Forced Oscillations of a Fractional Oscillator

Technical Physics Letters, 2018
A model of forced oscillations of an oscillator based on the fractional integro-differential formalism has been considered. It is shown that this model is in good agreement with the classical model of forced oscillations of an oscillator with viscous damping.

BISTABILITY OF HARMONICALLY FORCED RELAXATION OSCILLATIONS

International Journal of Bifurcation and Chaos, 2002
Relaxation oscillations appear in processes which involve transitions between two states characterized by fast and slow time scales. When a relaxation oscillator is coupled to an external periodic force its entrainment by the force results in a response which can include multiple periodicities and bistability.

Synchronization of a forced relaxation oscillator

International Journal of Circuit Theory and Applications, 1993
AbstractThe paper presents a method of synchronizing a relaxation oscillator to an external signal. the synchronization mechanism is linear and a detailed analysis is given. Very fast acquisition is shown to be possible. the oscillator synchronizes to the frequency of the forcing input or to a sub‐ or superharmonic.

Clinical Application of Forced Oscillation

Pulmonary Pharmacology & Therapeutics, 2001
This review summarizes current clinical use of the forced oscillation technique (FOT) for analysis of lung function. It presents an intuitive approach to FOT pattern recognition for interpretation of results in human subjects, and the view that FOT is now well established and, clinically, eminently useful in patients with airflow obstruction.

Identifying the presence of forced oscillations using oscillation signatures

2017 IEEE International Conference on Industrial and Information Systems (ICIIS), 2017
Forced oscillations in a power system are distin-guished from natural oscillations as a rouge oscillatory input to the system. Two examples for sources of these forced oscillations are a malfunctioning governor that has not been modeled or a cyclic load with a low frequency.

Forced oscillations in a rotating liquid (II)

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1962
Der vorliegenden Analyse liegen die linearisierten Gleichungen fur die achsensymmetrischen Storungen einer gleichformig rotierenden Flussigkeit zugrunde. Dabei wird aber keine Annahme hinsichtlich einer Zeitabhangigkeit der erzwungenen Bewegungen gemacht und die Entwicklung der Storungen vom Beginn der erzwungenen Bewegung an studiert.
