Period Doubling of Dissipative-Soliton-Resonance Pulses in Passively Mode-Locked Fiber Lasers

Frontiers in Physics, 2020
Period-doubled dissipative-soliton-resonance (DSR) pulses are numerically investigated in a Yb-doped fiber laser based on non-linear amplifying loop mirror (NALM).

Transition to Periodic Behaviour of Flow Past a Circular Cylinder under the Action of Fluidic Actuation in the Transitional Regime

Energies, 2021
This study focuses on the numerical investigation of the underlying mechanism of transition from chaotic to periodic dynamics of circular cylinder wake under the action of time-dependent fluidic actuation at the Reynolds number = 2000.

Predicting Tipping Points in Chaotic Maps with Period-Doubling Bifurcations

Complexity, 2021
In this paper, bifurcation points of two chaotic maps are studied: symmetric sine map and Gaussian map. Investigating the properties of these maps shows that they have a variety of dynamical solutions by changing the bifurcation parameter.

Chaos and period-doubling vibration in superconducting levitation systems

AIP Advances, 2020
For high-temperature superconducting levitation systems, chaotic vibrations occurred under external disturbance, as shown in previous studies. The electromagnetic characteristic of a high-temperature superconductor (HTSC) plays a crucial role in the ...

Phonetics of period doubling [PDF]

, 2023
The human voice is the most common `carrier' of speech, but how does linguistic voice quality affect speech production and perception? Typical `modal' voice possesses a single fundamental frequency (f0), identified as the voice's pitch.

CONNECTING PERIOD-DOUBLING CASCADES TO CHAOS [PDF]

International Journal of Bifurcation and Chaos, 2012
The appearance of infinitely-many period-doubling cascades is one of the most prominent features observed in the study of maps depending on a parameter. They are associated with chaotic behavior, since bifurcation diagrams of a map with a parameter often reveal a complicated intermingling of period-doubling cascades and chaos.Period doubling can be ...
