Categories of SHM Deployments: Technologies and Capabilities [PDF]

Journal of Bridge Engineering, 2015
The findings of an extensive literature survey focusing on bridge structural health monitoring (SHM) deployments are presented. Conventional, maturing, and emerging technologies are reviewed as well as deployment considerations for new SHM endeavors. The lack of published calibration studies (and quantification of uncertainty studies) for new sensors ...

SHM Maps and Conjugation [PDF]

Proceedings of the American Mathematical Society, 1974
We call two shm maps completely shm homotopic if one map is shm homotopic to a shm conjugation of the other. It is proved that there is a one-to-one correspondence between completely shm homotopy classes of shm maps on H-spaces and base point free homotopy classes of maps on their classifying spaces.
