Evaluation of Strategic Noise Maps Arising from Urban Traffic

open access: yesDoğal Afetler ve Çevre Dergisi, 2021
Environmental noise from traffic, industry and entertainment in cities has been one of the important environmental problems. In developed countries, noise from highways, airways and railways are the second major health problem. Traffic noise has negative

Meta-modeling for urban noise mapping

open access: yesThe Journal of the Acoustical Society of America, 2020
Urban noise mapping generally consists of simulating the emission and attenuation of noise in an area by following rules such as common noise assessment methods. The computational cost makes these models unsuitable for applications such as uncertainty quantification, where thousands of simulations may be required.

The noise of cluster mass reconstructions from a source redshift distribution [PDF]

open access: yes, 2001
The parameter-free reconstruction of the surface-mass density of clusters of galaxies is one of the principal applications of weak gravitational lensing. From the observable ellipticities of images of background galaxies, the tidal gravitational field (

People exposed to traffic noise in european agglomerations from noise maps. A critical review

open access: yesNoise Mapping, 2014
Two of the main objectives of the European Directive on environmental noise are, firstly, to unify acoustic indices for assessing environmental noise and, secondly, to standardize assessment methodologies.

Noiseless Collective Motion out of Noisy Chaos [PDF]

open access: yes, 1998
We consider the effect of microscopic external noise on the collective motion of a globally coupled map in fully desynchronized states. Without the external noise a macroscopic variable shows high-dimensional chaos distinguishable from random motion ...

Nonmonotonic Pattern Formation in Three Species Lotka-Volterra System with Colored Noise [PDF]

open access: yes, 2005
A coupled map lattice of generalized Lotka-Volterra equations in the presence of colored multiplicative noise is used to analyze the spatiotemporal evolution of three interacting species: one predator and two preys symmetrically competing each other. The

A chaotic switched-capacitor circuit for characteristic CMOS noise distributions generation [PDF]

open access: yes, 2017
A switched-capacitor circuit is proposed for the generation of noise resembling the typical noise spectral density of MOS devices. The circuit is based on the combination of two chaotic maps, one generating 1/f noise (hopping map) and the other ...

Assessment of Traffic Noise Pollution Due to Urban Residential Road Transport

open access: yesRomanian Journal of Transport Infrastructure, 2019
The problem of combating urban noise is closely linked to the rational transformation of the urban environment, which must go through the elimination or reduction of the number of sources of noise, the localization of the noise emission zone, reducing ...
