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 ...

NoiseSphere: An AI-Based Approach for Dynamic and Large-Scale Noise Mapping

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">Noise pollution is a major environmental and health challenge, yet its strong spatial and temporal variability makes comprehensive mapping highly complex. Current approaches under the European Noise Directive (END) provide only partial coverage and often lack temporal dynamics ...
