The state of the art of weld seam radiographic testing: Part II, pattern recognition
(AMER SOC NONDESTRUCTIVE TEST, 2007)
Over the last 30 years, there has been a large amount of research attempting to develop an automatic (or semiautomatic) system for the detection and classification of weld discontinuities in continuous welds examined by ...
A new bi-imaging NDT system for simultaneous recovery of attenuation and electronic density maps
(Confédération Française pour les Essais Non Destructifs, 2020)
Computed Tomography is a widely used imaging technique for non-destructive testing and evaluation in industry. Tomographic modalities exploit only primary radiation, which is non-deviated but attenuated radiation going ...
Comparative Study of three non-destructive techniques for metal loss inspection in pipe walls
(2020-05-19)
Identifying and describing metal loss defects in pipe walls is an indispensable task in
transporting operations, this abnormal condition mainly appears as a result of corrosion and
gouging. These metal losses can lead ...

Medição do perfil de velocidade por técnica ultrassônica utilizando o método da autocorrelação estendida e equipamento para ensaios não destrutivos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2016-11-04)
Interest in knowing the instantaneous velocity profile in fluid dynamics has grown in recent years as new flow visualization techniques are improving. In this context, the ultrasonic Doppler velocity profiler (UVP) has ...
O-H-Sr-Nd isotope constraints on the origin of the Famatinian magmatic arc, NW Argentina
(Cambridge University Press, 2020-12)
We report a study of whole-rock O-H-Sr-Nd isotopes of Ordovician igneous and metamorphic rocks exposed at different crustal palaeodepths along c. 750 km in the Sierras Pampeanas, NW Argentina. The isotope compositions ...
