Investigating the time dynamics of geoelectrical signals measured in two seismotectonic environments in the Mediterranean region: the Southern Apennine chain (Southern Italy) and the Hellenic arc (Crete Island, Greece)

Annals of Geophysics, 2000
In this paper we explore the time dynamics of geoelectrical signals measured in two seismic active areas in the Mediterranean region: the Southern Apennine chain (Italy) and the Hellenic arc (Crete Island, Greece).

Single particle tracking in systems showing anomalous diffusion: the role of weak ergodicity breaking

, 2010
Anomalous diffusion has been widely observed by single particle tracking microscopy in complex systems such as biological cells. The resulting time series are usually evaluated in terms of time averages.

Analysis of the Impact of Anomalous Noise Events on Road Traffic Noise Levels Computation from Urban and Suburban WASNs in real operation

, 2020
Among the different sources of environmental noise, Road Traffic Noise (RTN) has become the main acoustic pollutant in urban and suburban areas in recent years negatively affecting the quality of life of their citizens. In order to address this problem, the European authorities require their member states to fulfil the European Environmental Noise ...

Unsupervised Anomaly Detection and Localization Based on Deep Spatiotemporal Translation Network

IEEE Access, 2020
Anomaly detection is of great significance for intelligent surveillance videos. Current works typically struggle with object detection and localization problems due to crowded and complex scenes.

ANOMALOUS NOISE EVENTS CONSIDERATIONS FOR THE COMPUTATION OF ROAD TRAFFIC NOISE LEVELS: THE DYNAMAP'S MILAN CASE STUDY

24th International Conference on Sound and Vibration 2017, London Calling
Dynamic noise maps are computed to represent the noise levels generated by road traffic in realtime to determine the population exposure to environmental noise. To this aim, a network ofacoustic sensors can be deployed in representative street locations to capture and process rawacoustic data before estimating the equivalent noise levels (Leq) of ...

Entropic Approach to the Detection of Crucial Events

Entropy, 2019
In this paper, we establish a clear distinction between two processes yielding anomalous diffusion and 1 / f noise. The first process is called Stationary Fractional Brownian Motion (SFBM) and is characterized by the use of stationary correlation
