Mapping noise disturbed oscillators onto quasi-symplectic dynamics

2013 22nd International Conference on Noise and Fluctuations (ICNF), 2013
We find exact mappings for a class of limit cycle systems with noise onto quasi-symplectic dynamics, including a van der Pol type oscillator. A dual role potential function is obtained as a component of the quasi-symplectic dynamics. Each component of the quasi-symplectic dynamics has an individual physical meaning and can be measured independently ...

The Simulation of Noise Impact on the Dynamics of a Discrete Chaotic Map

2020
There is no clear understanding of the way how a noise influence on nonlinear dynamical systems with chaotic behaviour. Due to difficulties with analysis of real-world chaotic oscillators computer simulation is preferable. However, during the process of simulation, a noise presents too.

Influence of dynamical noise on time series generated by nonlinear maps

Physica D: Nonlinear Phenomena, 2008
Consider the dynamical noise called ``pseudonoise'' corrupting a time series generated by a discrete iterated function system (map). Especially, the discrete maps \[ x_{n+1} = f(x_n) \] modified by the two types of maps \[ y_{n+1} = f(y_n) + \eta_n \] or \[ z_{n+1} = f(z_n+\eta_n) \] with noise terms \(\eta_n\) are under consideration.

Symbolic dynamics of one-dimensional maps: Entropies, finite precision, and noise

International Journal of Theoretical Physics, 1982
In the study of nonlinear physical systems, one encounters apparently random or chaotic behavior, although the systems may be completely deterministic. Applying techniques from symbolic dynamics to maps of the interval, we compute two measures of chaotic behavior commonly employed in dynamical systems theory: the topological and metric entropies.

Stochastic dynamics of the cubic map: A study of noise-induced transition phenomena

Journal of Statistical Physics, 1983
The effects of finite-amplitude, additive noise on the dynamics generated by a one-dimensional, two-parameter cubic map are considered. The underlying deterministic system exhibits bistability and hysteresis, and noise-induced processes associated with these phenomena are studied. If a bounded noise source is applied to this system, trajectories may be

Effect of noise on the critical golden-mean quasiperiodic dynamics in the circle map

Physica A: Statistical Mechanics and its Applications, 2006
Abstract Scaling regularities are examined associated with effect of additive noise on a critical circle map at the golden-mean rotation number. We present an improved numerical estimate for the scaling constant of Hamm and Graham (Phys. Rev. A46, (1992) 6323) responsible for the effect of noise, γ = 2.3061852653 .

Toward a dynamic national transportation noise map: Modeling temporal variability of spectral traffic noise emission levels

The Journal of the Acoustical Society of America
The National Transportation Noise Map predicts time-averaged road traffic noise across the continental United States (CONUS) based on annual average daily traffic counts. However, traffic noise can vary greatly with time. This paper outlines a method for predicting nationwide hourly varying source traffic sound emissions called the Vehicular Reduced ...
