A composite structure having an embedded sensing system is provided, along with corresponding systems and methods for monitoring the health of a composite structure. The block has a pair of saw guides selectively attached thereto so as to be parallel to each other so that parallelism is maintained during the resurfacing process. In order to prevent a fire from occurring or at least to be able to rapidly extinguish a fire which has occurred, there is provided a first apparatus for producing an inert atmosphere. At the classifier configuration step, a classifier is configured by registering the ante-mounting features and the post-mounting features as training data to a support vector machine.
