Dynamic noise mapping of road traffic in an urban city
Arabian Journal of Geosciences, 2021This study is an attempt to analyse the spatial distribution of traffic noise levels in the city of Delhi through the creation of noise maps with the help of GIS. Field measurements were conducted at 10 locations consisting of different land-use patterns.

A WASN-Based Suburban Dataset for Anomalous Noise Event Detection on Dynamic Road-Traffic Noise Mapping [PDF]
Sensors, 2019 Traffic noise is presently considered one of the main pollutants in urban and suburban areas. Several recent technological advances have allowed a step forward in the dynamic computation of road-traffic noise levels by means of a Wireless Acoustic Sensor Network (WASN) through the collection of measurements in real-operation environments.

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 ...

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.

Mapping noise disturbed oscillators onto quasi-symplectic dynamics
2013 22nd International Conference on Noise and Fluctuations (ICNF), 2013We 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 ...

Crowdsourcing Application in the Development of a Dynamic Noise Map
2021One of the most important components of smart cities are smart citizens, i.e. people who actively participate in the functioning of the city. Current commu-nication technologies and smart devices are components that make this possible in near real-time.

Rendering of Dynamic Road Traffic Noise Map based on Paramics
Procedia, Social and Behavioral Sciences, 2013 AbstractTraffic flow is simplified as equal-interval line source in traditional road traffic noise prediction models. The prediction results of these models are non-dynamic and can only be used to render the static noise maps. This paper performs the dynamic simulation of road traffic noise by integrating traffic micro-simulation technology, noise ...

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 ...
