Damage Detection and Damage Detectability— Analysis and Experiments
Journal of Aerospace Engineering, 1997A technique to identify structural damage in real time using limited instrumentation is presented. Contrast maximization is used to find the excitation forces that create maximum differences in the response of the damaged structure and the analytical response of the undamaged structure. The optimal excitations for the damaged structure are then matched

Science Signaling, 2008
A break in both strands of the DNA double helix is potentially very dangerous for organisms because the free ends can recombine inappropriately with other parts of the genome and cause substantial damage. Eukaryotic cells sense and attempt to repair such breaks very rapidly, through the recruitment of DNA repair proteins to the sites of damage, forming

Damage Detection in Flexible Structures
Journal of Sound and Vibration, 1993Abstract A method is developed for the detection of the existence and location of structural damage. Structural damage is considered to be at the macroscopic level. The detection is carried out in two parts. In the first part, the eigensolution of the structure is identified using a modal parameter identification technique and the system response ...

Science's STKE, 2003
Protein complexes called tight junctions hold adjacent cells of an epithelial monolayer tightly together, creating a physical barrier between apical and basolateral membranes. Vermeer et al. show that in human airway epithelia, tight junctions keep the growth factor heregulin, and its receptor, erbB2, apically and ...

Damage detection with auxiliary subsystems [PDF]
, 2008 The small sensitivity to local variations of mechanical characteristics turns out to be the major limit of indirect identification techniques based on frequency response measurements. To overcome this limit, the use of sensitivity enhancement techniques has recently proposed: the monitored structure is coupled to an auxiliary system, the constitutive ...

Damage detection using generic elements: Part II. Damage detection
Computers & Structures, 2003This paper proposes the use of generic elements in damage detection, based on the use of an updated baseline finite element model, modal sensitivities and changes in the measured modal quantities arising from structural damage. A companion paper presented the fundamental theory of model updating and generic element or substructure parameterisation. The
