On detecting harmonic oscillations

Bernoulli, 2015
International audienceIn this paper, we focus on the following testing problem: assume that we are given observations of a real-valued signal along the grid 0, 1, . . . , N − 1, corrupted by white Gaussian noise.

All Conditions for Synchronous Harmonic Natural Oscillations in LC Circuits

IEEE Transactions on Circuits and Systems II: Express Briefs, 2022
The full set of conditions for synchronous harmonic oscillations in multiple LC circuits are established. These are for discrete lossless linear systems in source-free response.

Nonlinear harmonic oscillators

Journal of Physics A: Mathematical and General, 2002
This paper deals with the existence of assembles of an arbitrary number of complex oscillators, or equivalently of an arbitrary even number of real oscillators, characterized by Newtonian equations of motion (``acceleration equal force'') with one-body velocity-dependent linear forces and many-body velocity-independent cubic forms, all the nonsingular ...

Harmonic Oscillators with Nonlinear Damping

International Journal of Bifurcation and Chaos, 2017
Dynamical systems with special properties are continually being proposed and studied. Many of these systems are variants of the simple harmonic oscillator with nonlinear damping. This paper characterizes these systems as a hierarchy of increasingly complicated equations with correspondingly interesting behavior, including coexisting attractors, chaos ...
