Sub harmonic oscillations in first order systems with delay

open access: yesVietnam Journal of Mechanics, 1990
The sub harmonic oscillations with frequency, which is n times smaller than that of exciting periodic force, in first order systems with delay are studied. The averaging equations for the am altitude and phase of the response are constructed. A detailed

Enhanced Speed Control of a Drive With Rejection of Periodical Disturbances

open access: yesIEEE Open Journal of the Industrial Electronics Society, 2022
The present work deals with the enhancement of the speed control of an electrical drive under a repetitive mechanical load. In such a system, the load torque changes periodically according to the angular position of the rotor causing speed oscillations ...

Shape analysis of gamma rhythm supports a superlinear inhibitory regime in an inhibition-stabilized network.

open access: yesPLoS Computational Biology, 2022
Visual inspection of stimulus-induced gamma oscillations (30-70 Hz) often reveals a non-sinusoidal shape. Such distortions are a hallmark of non-linear systems and are also observed in mean-field models of gamma oscillations.

A note on the method of harmonic balance

open access: yesVietnam Journal of Mechanics, 2001
Free oscillation period of the Duffing oscillator with cubic non-linearity was examined. A comparison between the exact period and those obtained by the asymptotic and the harmonic balance methods was done.

ADELIC HARMONIC OSCILLATOR [PDF]

open access: yesInternational Journal of Modern Physics A, 1995
Using the Weyl quantization we formulate one-dimensional adelic quantum mechanics, which unifies and treats ordinary and p-adic quantum mechanics on an equal footing. As an illustration the corresponding harmonic oscillator is considered. It is a simple, exact and instructive adelic model. Eigenstates are Schwartz-Bruhat functions.

Azimuthally-differential pion femtoscopy relative to the third harmonic event plane in Pb–Pb collisions at sNN=2.76TeV

open access: yesPhysics Letters B, 2018
Azimuthally-differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze out, provide very important information on the nature and dynamics of the system ...

Forced harmonic oscillations of the Euler-Bernoulli beam with resistance forces

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2015
The important issue in the oscillation theory is the study of resistance impact on oscillatory processes. Unlike the calculations of free oscillations, that reside in determination of natural frequencies and waveshapes and unlike the calculations of ...
