Generalization of anomaly detection in bridge structures using a vibration‐based Siamese convolutional neural network

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 18, Page 2751-2768, 18 July 2025.
Abstract Corrosion is one of the main damages in steel bridges, which appears as a loss of material and sectional area and causes member failure over time. A reliable bridge management system not only should help in preventing catastrophic structural failure by employing an in‐time anomaly detection approach for all the bridges within a network but ...

Reassigning and synchrosqueezing the Stockwell Transform: Complementary proofs

open access: yes, 2015
The S-transform is an efficient tool for time-frequency analysis that gained interest in many signal processingapplication fields. This is due to its ability to produce an analysis with a frequency dependent resolution, as for the wavelettransform, while

How Orienting and Defence Drives Oscillatory Responses in Human Visual and Motor Cortical Circuits During Viewing of Threat Pictures: Evidence From ssVEPs and Beta‐Band Desynchronization

open access: yesEuropean Journal of Neuroscience, Volume 61, Issue 12, June 2025.
Healthy human participants engage mainly in two fundamental response strategies towards threat related picture content: orienting and defence. Orienting has been associated with heart rate (HR) deceleration, whereas defence evokes HR acceleration.

THE APPLICATION OF LCD AND SWT IN FAULT DIAGNOSIS OF ROLLING BEARING

open access: yesJixie qiangdu, 2019
In order to overcome the difficulty of feature extraction of non-stationary faulty signals in rolling bearing fault diagnosis under strong noise background, a method based on local characteristic-scale decomposition and synchrosqueezing wavelet transform

The Synchrosqueezing transform for instantaneous spectral analysis

open access: yes, 2014
The Synchrosqueezing transform is a time-frequency analysis method that can decompose complex signals into time-varying oscillatory components. It is a form of time-frequency reassignment that is both sparse and invertible, allowing for the recovery of ...

Second-order Synchrosqueezing Transform: The Wavelet Case and Comparisons

open access: yes, 2017
This paper addresses the analysis of the time-frequency technique so-called the second-order synchrosqueezing transform derived from continuous wavelet transform of multicomponent AM-FM signals.

Recursive versions of the reassigned scalogram anc of the synchrosqueezed wavelet transform

open access: yes2017 22nd International Conference on Digital Signal Processing (DSP), 2017
This paper introduces a new class of mother wavelet functions, based on a specific analysis window which allows a recursive implementation of the Continuous Wavelet Transform (CWT). Using this new transform, we propose to compute a sharpened time-frequency representation by rewording the reassigned scalogram and the (first and second-order ...

Radar Waveform Recognition using Fourier-Based Synchrosqueezing Transform and CNN

open access: yes, 2019
In this paper the problem of recognizing radar waveforms is addressed. Waveform classification is needed in spectrum sharing and radar-communications coexistence, cognitive radars and signal intelligence.
