【Awards and Commendations】Hiromitsu Fujii, Department of Precision Engineering, wins the prize of Research Encouragement Award from The Japan Society for Precision Engineering.

Hiromitsu Fujii, Department of Precision Engineering, the prize of Research Encouragement Award related to the paper, which was published on Journal of the Japan Society for Precision Engineering Vol. 80(2014) No. 12, from The Japan Society for Precision Engineering.

Under such a background, hammering test, a traditional inspection method which can detect defect state of the target from the difference of sounds obtained by hitting it, has attracted attention again. In the awarded paper, we proposed a basic algorithm for online defect detection using hammering sounds. Applying our method to crack detection of an office building, locations of not only the cracks but also inner structure behind wall, such as blank space and metal beams, were detected correctly.

We intend to expand our system so that it can be applied to other social problems, such as concrete tunnel inspection, which is highly demanded.
