Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article focuses on the characterization and size estimation of incipient cracks in aviation engine blades using Eddy Current Testing (ECT). It introduces a novel method combining Jensen–Shannon Divergence and Wasserstein Distance to accurately characterize cracks, even those with similar surface areas. Additionally, the study presents a correction method for simulation signals, enhancing the accuracy of finite element modeling (FEM) in ECT. This approach extends experimental data and enables precise estimation of crack sizes, making it a valuable resource for professionals in the field of structural health monitoring and aerospace engineering.
