Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 20, Page 3033-3052, 18 August 2025.Abstract Signal noise removal is an indispensable and critical procedure in obtaining clean pavement texture data for reliable pavement evaluation and management. Nevertheless, the presently established denoising approaches to pavement texture data still rely on traditional techniques that have long struggled with removing noise accurately and ...

Reassigning and synchrosqueezing the Stockwell Transform: Complementary proofs
, 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

Computer-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 ...

The Synchrosqueezing transform for instantaneous spectral analysis
, 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 ...

Wavelet-Enhanced Time-Frequency Analysis Method for Bearing Fault Detection of Rotating Machinery
IEEE AccessIn industrial settings, analyzing vibration signals from rolling bearings is a key method for diagnosing faults in rotating machinery. However, these faults often appear as a series of transient events with quickly changing frequencies, which makes it ...

High-Order Adaptive Synchrosqueezing Transform
, 2020 The prevalence of the separation of multicomponent non-stationary signals across many elds of research makes this concept an important subject of study. The synchrosqueezing transform (SST) is a particular type of reassignment method. It aims to separate
