Dynamic noise maps for Ljubljana airport
Proceedings of 10th SESAR Innovation Days, 2020 The main purpose of this research is to assess the impact of aircraft noise around an airport considering spatial and temporal variations in the population. The concept of dynamic airport noise mapping has been demonstrated on Ljubljana airport case study. Detailed population mobility information for Slovenia were retrieved from a survey.

Ensembling Multiple Radio Maps with Dynamic Noise in Fingerprint-based Indoor Positioning [PDF]
2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 2021 Ponencia presentada en 2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 25-28 April 2021 Fingerprint-based indoor positioning is widely used in many contexts, including pedestrian and autonomous vehicles navigation. Many approaches have used traditional Machine Learning models to deal with fingerprinting, being k-NN the

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.

Symmetrized importance samplers for stochastic differential equations [PDF]
, 2018 We study a class of importance sampling methods for stochastic differential equations (SDEs). A small-noise analysis is performed, and the results suggest that a simple symmetrization procedure can significantly improve the performance of our importance ...

Image Encryption Algorithm Based on a Novel Wide-Range Discrete Hyperchaotic Map
Mathematics, 2022 Existing hyperchaotic systems suffer from a small parameter range and small key space. Therefore, we propose herein a novel wide-range discrete hyperchaotic map(3D-SCC) based on the mathematical model of the Sine map.
