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.

Simultaneous Oscillations in Oscillators
Transactions of the IRE Professional Group on Circuit Theory, 1954An oscillator with two degrees of freedom can, under certain conditions, oscillate simultaneously at two different frequencies. The ratio of the two frequencies may be rational (synchronous oscillations) or irrational (asynchronous oscillations). The conditions necessary for 'simultaneous oscillations are discussed for these two cases.

Reviving Oscillations in Coupled Nonlinear Oscillators
Physical Review Letters, 2013By introducing a processing delay in the coupling, we find that it can effectively annihilate the quenching of oscillation, amplitude death (AD), in a network of coupled oscillators by switching the stability of AD. It revives the oscillation in the AD regime to retain sustained rhythmic functioning of the networks, which is in sharp contrast to the ...

“Oscillating” Metallocene Catalysts: How Do They Oscillate?
Angewandte Chemie International Edition, 2002Based on the results of a series of propylene polymns. using oscillating metallocene catalysts of type [(2-Ar-indenyl)2ZrCl2] (Ar = C6H5 or 3,5-(t-Bu)2-4-MeO-C6H2) with various cocatalysts (MAO, TIBAl), the oscillating behavior of the zirconocenes is discussed with respect to the rac/meso stereochem. outcome of the obtained polypropylenes.

Oscillations in an Ensemble of Noninteracting Oscillators [PDF]
, 1989 The two most important cases in application are the almost trivial one in which all the oscillators are identical and the much more interesting one when the parameters of the oscillators are scattered either in frequency or in damping. The consideration of the behavior of an ensemble of identical noninteracting oscillators is the main subject of the ...

Oscillation death in coupled oscillators
Frontiers of Physics in China, 2009We study dynamical behaviors in coupled nonlinear oscillators and find that under certain conditions, a whole coupled oscillator system can cease oscillation and transfer to a globally nonuniform stationary state [i.e., the so-called oscillation death (OD) state], and this phenomenon can be generally observed.

Evolution of Oscillation in a Quadrature Oscillator
2011 24th Internatioal Conference on VLSI Design, 2011The growth of oscillation in a quadrature oscillator that employs phase shifters in the coupling-path between a pair of LC-loaded negative resistance cores, is analyzed. Such an oscillator is known to have two stable modes of oscillation. Under a noise-initiated startup from an unstable initial condition, quasiharmonic assumption and the Method of ...

18. Operating Point on the Characteristic Curve By operating point on the characteristic curve is meant the point on the E c — I b curve of the audion about which the grid potential and space current vary. E c is the potential of the grid with respect to the filament. If a continuous negative potential such as Q Fig.

Superpositions of oscillations and quasi-oscillations
Acta Mathematica Hungarica, 2003If X is a topological space and (Y,d) is a metric space, then for each locally bounded function f : X→Y all possible superpositions of oscillations and quasi-oscillations give at most eight functions.

, 1989 As an application of the Schrodinger equation, we now calculate the states of a particle in an oscillator potential. From classical mechanics we know that such a potential is of greater importance, because many complicated potentials can be approximated in the vicinity of their equilibrium points by a harmonic oscillator.
