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

In this paper, a new online damage detection method is developed using displacement and velocity measurements of the structure. The proposed method is an improved synchronization-based approach in which any changes in system parameters can be measured by synchronizing a mathematical model with the real model of the structure in real time. Several damage scenarios for structures subjected to different seismic ground motion acceleration records are studied to validate the effectiveness of the proposed method. The effect of noise on the performance of the proposed algorithm is also investigated and discussed. Numerical results demonstrate that the proposed technique has the capability of tracking the abrupt changes of stiffness and damping parameters with high accuracy in real time.
