New Features for Damage Detection and Their Temperature Stability
Autor: José Rodellar, Fahit Gharibnezhad, Luis Eduardo Mujica Delgado
This chapter is devoted to present novel techniques in Structural Health Monitoring (SHM). These techniques are based on different statistical and signal processing methods that are used in other fields but their performance and capability in SHM is
