Structural FRF acquisition via electric impedance measurement applied to damage location
(Soc Experimental Mechanics Inc, 2000-01-01)
Continuing development of new materials makes systems lighter and stronger permitting more complex systems to provide more functionality and flexibility that demands a more effective evaluation of their structural health. ...
Real Time Delta Extraction Based on Triggers to Support Data Warehousing
(Ieee, 2013-01-01)
Nowadays large corporations require integrated data from diverse sources, leading to the use of data warehouse architectures for this purpose. To bypass problems related to the use of computational resources to process ...
Morphological and molecular analysis of the collagen fibers in inflammatory process
(2011-07-25)
Collagen makes up one third of the total protein in humans, being formed by the connection of three polypeptide chains arranged in a triple helix. This protein has fundamental importance in the formation of extracellular ...
