Our data set consist of impact-echo, ultrasound (US) and ground penetrating radar data collected on a large concrete slab with embedded simulated honeycombing defects. USperforms best in defect discriminating and sizing, however the false positive rate is still high. We fuse the data set using ...
This is in contrast to many dimer models where the dimers are two spin-1/2 singlets. The elementary excitations of H0 (which take one out of the loop covering manifold) are loop “cuts”: a loop is cut open, which creates nearby two (defect) bonds covered by one orbital rather than ...
Concrete evaluationHoneycombingMachine learningClusteringWe use three clustering algorithms to aggregate a three-modal non-destructive testing data set into defect and not-defect groups. Our data set consist of impact-echo, ultrasound (US) and ground penetr...
Concrete evaluationHoneycombingWe laid out a novel conceptual framework for multi-sensor defect classification.No well-established technique for honeycomb detection.New methods to extract information (features) from each sensor data are presented.We introduce two conceptually simple yet effective fusion ...
It is used as a tool to estimate the change in temperature or thermal contrast induced by the presence of a defect in specimen besides using numerical simulation based on FEM to develop the prediction of temperature development in concrete structure. Findings – This study shows that the ...
A method of detecting honeycombing damage in a reinforced concrete beam using the finite element model updating technique was proposed. A control beam and two finite element models representing different severity of damage were constructed using available software and the defect parameters were updated....
