Detection of dis-bond between honeycomb and composite facesheet of an Inner Fixed Structure bond panel of a jet engine nacelle using infrared thermographic techniques
TLDR
The Inner Fixed Structure (IFS) bond panel is a honeycomb sandwich panel with CFRP facesheet and a heat shield on one side, and a perforated CFRP faceheet on the other side, of a jet engine nacell as mentioned in this paper.Abstract:

A study on the use of fundamental antisymmetric-like guided wave for health monitoring of elastic–viscoelastic bilayer structures
TL;DR: In this article , an ultrasonic guided wave propagation in an elastic-viscoelastic (steel-rubber) bilayer structure was investigated and several wave features, such as amplitude, phase velocity and phase delay, were measured and compared to determine the characteristic changes of the A0 wave mode in the steel layer alone as well as in the bilayer structures.

Infrared Sensation-Based Salient Targets Enhancement Methods in Low-Visibility Scenes
TL;DR: Wang et al. as mentioned in this paper proposed a threshold denoising model based on wavelet transformation with bilateral filtering (WTBF) and a salient components enhancement method based on a multi-scale retinex algorithm combined with frequency-tuned salient region extraction (MSRFT).
