, 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 ...

An online graph-based anomalous change detection strategy for unsupervised video surveillance
EURASIP Journal on Image and Video Processing, 2019 Due to various accidents and crime threats to an unspecified number of people, many surveillance technologies have been studied as an interest in individual security continues to increase throughout society.

24th International Conference on Sound and Vibration 2017, London CallingDynamic 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 the ...

An image segmentation based algorithm for imaging of slow slip earthquakes
Geodesy and Geodynamics, 2018 Laboratory experiments next to a variety of observations, especially in subduction zones, have explored the existence of a premonitory stable slow slip growth phase preceding large earthquakes.

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

, 2021 The LIFE+ DYNAMAP project aims at creating dynamic road traffic noise maps automatically upon the levels measured by a low cost sensors network. To ensure these maps reflect the acoustic impact of road infrastructures, it is necessary to exclude other acoustic sources (e.g. aircrafts, industries, etc.) from the noise level computation.

Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...
