Thermographic signal reconstruction (TSR) and partial least squares thermography (PLST) are techniques conceived for the processing and analysis of pulsed thermography (PT) data. In this work, the capabilities of both techniques are evaluated. A thermal data sequence was obtained from a PT inspection on a carbon fiber reinforced polymer (CFRP) specimen with simulated delaminations (Teflon inser...

The aim of this paper is to present the advantages of using Digital Image Correlation (DIC) and Infrared Thermography (IRT) to investigate the thermomechanical behavior of aluminum at the scale of its microstructure. The study combines these complementary imaging techniques: Electron Backscatter Diffraction (EBSD) to characterise the microstructure of the sample, DIC to obtain strain fields and...

In this area, there was a large group of well women aged over 35 years eager for breast screening. For this survey using clinical examination, thermography, and mammography, we selected women considered to be at higher than average risk of breast cancer. Initially, unselected women were seen, by appointment, for clinical examination and thermography (see pp. 1664-1670, this issue). From that gr...

In this case study of a unique instance, the effects of non-invasive generated shockwaves onto the skin and the underlying fat tissue of a cellulite-afflicted, 52-year-old woman were investigated. The treatment was applied at the lateral thighs once per week for a period of 10 weeks. Diagnostic high-resolution ultrasound (Esaote 25 Gold® device with 15–18 MHz linear probe), thermography (Thermo...

None of the conventionally displayed images of lock-in thermography (in-phase or 0° image, out of phase or -90° image, amplitude image, phase image) is able to become inverted in the presence of emissivity contrast. The phase signal is inherently emissivity-corrected, but here contributions of different heat sources superimpose very nonlinearly, which prevents any meaningful deconvolution. It i...

Thin stone wall cladding systems used on exterior building envelopes typically consist of stone panels made of granite. There is a risk of detachment if the cement used to stack the panels is defective. There is awide range of destructive techniques to evaluate the state of the facades, but they are scarcely practical. Infrared thermography (IRT) offers a cost-effective alternative to tradition...

This paper reports a noncontact inspection method, using Pulsed Eddy Current (PEC) stimulated thermography, for the evaluation of the anisotropic dependency of electrical conductivity of steel exposed to tensile stress. This method combines microscope lens based thermography with PEC using a rectangular excitation coil, giving directional excitation, to infer the electromagnetic properties vari...

Composite materials are often more practical in use for different military applications. These materials provide interesting results especially through their good strength properties, corrosion resistance and low specific weight. These materials have various structures. Any defect of these materials usually has a more complicated and other form than in metals and that is why methods and diagnos...

The broad aim of this study was to determine whether bedding level in the transport trailer influenced pig performance and welfare. Specifically, the objective was to define the bedding requirements of pigs during transportation in commercial settings during cold and mild weather. Animals (n = 112,078 pigs on 572 trailers) used were raised in commercial finishing sites and transported in traile...
