Dynamic traffic noise maps based on noise monitoring and traffic speed data
Transportation Research Part D: Transport and Environment, 2021Abstract Unlike the current methods for dynamic traffic noise maps by using traffic flow as the non-acoustic road-related parameter to predict the noise emission of the whole road network, this study proposes a new method for dynamic updates of traffic noise maps in large regions based on noise monitoring and traffic speed data.

Estimation of Dynamic Noise in Mandelbrot Map
International Journal of Artificial Life Research, 2017Julia and Mandelbrot sets have been studied continuously attracting fractal scientists since their creation. As a result, Julia and Mandelbrot sets have been analyzed intensively. In this article, researchers have studied the effect of noise on these sets and analyzed perturbation.

Wireless Noise Surveillance - Development of Dynamic Noise Maps
SPE International Conference and Exhibition on Health, Safety, Security, Environment, and Social Responsibility, 2016Abstract Noise is a major challenge in the petroleum industry. Prior to performing work in a noisy area, the noise map is the tool for assessing noise exposure when planning and performing work. The aim of this paper is to present an ongoing R&D project to develop a wireless noise monitoring system that provides real-time input to a ...

Impact of the parametric noise on map-based dynamical systems
AIP Conference Proceedings, 2018Discrete-time nonlinear dynamical systems with general parametric stochastic disturbances are considered. For such systems, a problem of the probabilistic analysis of the random states dispersion around attractors is studied. For the constructive approximation of probabilistic distributions, the method of the stochastic sensitivity is developed. Matrix

Noise-aided control of chaotic dynamics in a logistic map
Physical Review E, 2000Controlling chaos involves employing small perturbations to a control parameter, resulting in the stabilization of the system (naturally chaotic) on one of the infinite unstable periodic orbits embedded in the chaotic attractor. In this Brief Report we study the constructive role of external noise in increasing the efficiency of controlling chaos ...

A discrete map for the dynamics of recurrent excitatory neural networks in the presence of noise
Biosystems, 1998We investigate the effect of the neuron characteristics on the behavior of a recurrent excitatory neural network model. First, we present the different types of dynamics obtained with simulations of a network of coupled excitatory spike-response neuron models placed under the influence of noise. Then, we derive a discrete map describing the dynamics of

Dynamical Systems Described by Discrete Maps with Noise
1981Since this contribution is one of the first in this volume and this conference is a truly interdisciplinary one, it might be useful to begin with a few general comments before entering the more technical part of our contribution.
