IMPLEMENTAZIONE DI TECNICHE NDT DI TERMOGRAFIA AD INFRAROSSI SU PANNELLI IN COMPOSITO GRP PER APPLICAZIONI NAUTICHE [PDF]

, 2010
Il presente lavoro descrive l’implementazione di due tecniche di termografia attiva ad infrarossi per il controllo non distruttivo (IRNDT) di delaminazioni sub-superficiali su pannelli in composito (GRP) di grosso spessore, tipicamente impiegati per uso ...

Defect Visualization and Effective Data Compression Techniques for Infrared Pulsed Thermography

Proceedings of the 2015 Asia International Conference on Quantitative InfraRed Thermography, 2015
In Pulsed thermography experiment depending on the camera specification one deal with a 3D data of large size, extracting the relevant information from the experimental data can be quite tedious. For doing any inferential and quantitative analysis from the thermography data in a semi-automated and automated manner it is necessary that the dimension of ...

Tracking plant condition in a functionally diverse restored plant community through a combination of proxy indicators

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
This study evaluates near‐surface remote sensing methods—leaf‐level thermography and hyperspectral reflectance—for estimating physiological parameters and monitoring seasonal changes in restored plant communities in Western Australia. Results show strong predictive accuracy for leaf water content and chlorophyll concentration, and multivariate analyses

Light‐Activated Micromotors in Air Propelled by Thermal Convection

Advanced Materials, Volume 38, Issue 1, 2 January 2026.
Near‐infrared‐driven micromotors in air can overcome gravity and generate convective motion by a light‐induced thermal mechanism driven by a temperature gradient in the air caused by the interaction of the gold nanoparticles present on the surface of ZnO and NIR irradiation.

Inspection of silver-sinter die attaches by pulsed and lock-in infrared thermography with flash lamp and laser excitation

, 2020
In this study we demonstrate the capabilities of the IR thermography for the inspection of silver-sinter die attaches. Sintered specimens such as 15 x 15 mm2 dummy dies sintered on AMB substrates have been measured by pulsed infrared thermography (PIRT),

Automatic Extraction of Material Defect Size by Infrared Image Sequence

Applied Sciences, 2020
A typical pulsed thermography procedure results in a sequence of infrared images that reflects the evolution of temperature over time. Many features of defects, such as shape, position, and size, are derived from single image by image processing.

Nitric oxide donation lowers blood pressure in adrenocorticotrophic hormone-induced hypertensive rats.

, 2004
Adrenocorticotrophic hormone (ACTH) elevates systolic blood pressure (SBP) and lowers plasma reactive nitrogen intermediates in rats. We assessed the ability of NO donation from isosorbide dinitrate (ISDN) to prevent or reverse the hypertension caused by

Comparative study on point and line thermographic inspection for fiber orientation assessment of randomly oriented strand material

Journal of the Brazilian Computer Society, 2018
Composite materials are being successfully used in aeronautics for more than two decades. This great success is mainly because this kind of materials is typically lighter when compared to metals and more resistant to corrosion.
