Oscillations of a forced asymmetric oscillator at resonance
Nonlinearity, 2000The 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 \(n\).

Forced oscillations in oscillator circuits, and the synchronization of oscillators
Journal of the Institution of Electrical Engineers - Part III: Radio and Communication Engineering, 1945The behaviour of a feedback oscillator circuit under the influence of an injected tone having a frequency close to the natural frequency of oscillation is considered from the point of view of the steady-state equilibrium of the loop transmission circuit.

Analysis of Forced Oscillations of a Fractional Oscillator
Technical Physics Letters, 2018A 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, 2002Relaxation 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.

Forced Oscillations of Extensible Beams
SIAM Journal on Mathematical Analysis, 1985The 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.

Synchronization of a forced relaxation oscillator
International Journal of Circuit Theory and Applications, 1993AbstractThe 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, 2001This 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.
