    FBGs are excellent strain sensors, because of its low size and multiplexing capability. Tens to hundred of sensors may be embedded into a s tructure, as it has already been demonstrated. Nevertheless, they only afford ...
  • Active piezoelectric system using PCA 

    Tibaduiza Burgos, Diego Alexander; Mujica Delgado, Luis Eduardo; Güemes Gordo, Alfredo; Rodellar Benedé, José (2010)
    Conference report
    Restricted access - publisher's policy
    In previous work by the authors, an aircraft turbine blade was used to show that T and Q-statistics formulation based in Principal Components Analysis (PCA) are successful indices to detect and distinguish damages. In ...
  • Damage detection in composite materials structures under variable loads conditions by using fiber Bragg gratings and principal component analysis, involving new unfolding and scaling methods 

    Sierra Pérez, Julian; Güemes Gordo, Alfredo; Mujica Delgado, Luis Eduardo; Ruiz Ordóñez, Magda (2014-06-03)
    Article
    Restricted access - publisher's policy
    An innovative methodology based on the use of fiber Bragg gratings as strain sensors and strain field pattern recognition is proposed for damage detection in composite materials structures. The strain field pattern recognition ...
  • Feasibility of structural health monitoring of concrete structures by optical backscatter reflectometer 

    Villalba Herrero, Sergi; Fernández López, Antonio; Casas Rius, Joan Ramon; Güemes Gordo, Alfredo (2009-09)
    Conference report
    Open Access
    The use of Optical Backscaterr Reflectometer (OBR) sensors is a promising measurement technology for SHM as it offers the possibility of continuous monitoring of strain and temperature along the fibre. Several applications ...

    Structural Health Monitoring is becoming more and more used in civil engineering infrastructure. The technology for implementing SHM applications is presented in this Chapter. Details on instrumented civil constructions ...
  • Principal component analysis vs. independent component analysis for damage detection 

    Tibaduiza Burgos, Diego Alexander; Mujica Delgado, Luis Eduardo; Anaya, Maribel; Rodellar Benedé, José; Güemes Gordo, Alfredo (2013)
    Conference report
    Open Access
    In previous works, the authors showed advantages and drawbacks of the use of PCA and ICA by separately. In this paper, a comparison of results in the application of these methodologies is presented. Both of them exploit ...
  • Structural damage detection using principal component analysis and damage indices 

    Tibaduiza Burgos, Diego Alexander; Mujica Delgado, Luis Eduardo; Rodellar Benedé, José; Güemes Gordo, Alfredo (2015-01-08)
    Article
    Open Access
    One of the most important tasks in structural health monitoring corresponds to damage detection. In this task, the existence of damage should be determined. In the literature, several potentially useful techniques for ...
