Previously, a nonlinear autoregressive network with exogenous input (NARX) demonstrated an excellent performance, far outperforming an established method in optimal baseline subtraction, for defect detection in guided wave signals. The principle is t

Location Specific Temperature Compensation of Guided Wave Signals in Structural Health Monitoring

Autor: Stefano Mariani, Peter Cawley, Sebastian Heinlein

Publikováno v: IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. 67:146-157

In guided wave structural health monitoring, defects are typically detected by identifying high residuals obtained through the baseline subtraction method, where an earlier measurement is subtracted from the "current" signal. Unfortunately, varying e

International audience; Widespread preservation of fossilized biomolecules in many fossil animals has recently been reported in six studies, based on Raman microspectroscopy. Here, we show that the putative Raman signatures of organic compounds in th

Evaluation of the sparse reconstruction and the delay-and-sum damage imaging methods for structural health monitoring under different environmental and operational conditions

Autor: Roger M. Groves, H.M. Navazi, A. Nokhbatolfoghahai

Publikováno v: Measurement, 169

In this paper, the performance of the sparse reconstruction (SR) and the delay-and-sun (DAS) methods for damage localization, were evaluated for various environmental and operational conditions, both numerically and experimentally. To assess these da

Compensation for temperature-dependent phase and velocity of guided wave signals in baseline subtraction for structural health monitoring

Autor: Sebastian Heinlein, Peter Cawley, Stefano Mariani

Baseline subtraction is commonly used in guided wave structural health monitoring to identify the signal changes produced by defects. However, before subtracting the current signal from the baseline, it is essential to compensate for changes in envir

Purpose To compare transverse relaxation rates of brain metabolites estimated from single-TE PRESS acquisitions with more conventionally derived rates estimated from multiple-TE PRESS acquisitions. Methods Single-voxel (8 mL) PRESS data within white
