A nonlinear analysis on the three oscillation modes of a bifilar suspension pendulum (1) (Formulation of nonlinear oscillation problem and primary resonance analysis of one degree of freedom nonlinear inertia type forced damping systems)

open access: yesNihon Kikai Gakkai ronbunshu, 2019
A bifilar suspension pendulum, a uniform density bar suspended at its two points by two strings of same length from an upper horizontal plane, may swing in two vertical planes or make torsional oscillation about a vertical axis.

Mixed-mode oscillations with multiple time scales

open access: yes, 2010
Mixed-mode oscillations (MMOs) are trajectories of a dynamical system in which there is an alternation between oscillations of distinct large and small amplitudes.

Oscillation frequencies of moderately rotating delta scuti stars: asymmetric mode splittings due to non-spherical distortion [PDF]

open access: yes
We find that the observed pressure-mode rotational splittings of slowly/moderately rotating Scuti stars and Cephei stars mostly have a positive asymmetry.

Some Results on Oscillation Stability in Multi-Mode Harmonic Oscillators

open access: yes, 2023
We study the stability of oscillation in two different multi-mode harmonic oscillators by means of Barkhausen’s criterion, involving a minimum of mathematical machinery in favor of a more intuitive, circuit-based approach.

Oscillations in the primordial bispectrum: Mode expansion [PDF]

open access: yesPhysical Review D, 2010
We consider the presence of oscillations in the primordial bispectrum, inspired by three different cosmological models; features in the primordial potential, resonant type non-Gaussianities and deviation from the standard Bunch Davies vacuum. In order to put constraints on their bispectra, a logical first step is to put these into factorized form which

Geodesic Acoustic Mode Oscillation in the Low Frequency Range

open access: yes, 2005
"In this paper, the Geodesic Acoustic Mode theory is reconsidered with regard to the linear dispersion relation obtained previously by use of the drift kinetic equation. Specifically, kinetics effects in the low frequency range are handled more precisely,
