Visit to the Department of Mechanical Engineering of the Eindhoven University of Technology

Category : News

In January 2018, Dr. Lara del Val visited the Department of Mechanical Engineering of the Eindhoven University of Technology, invited by Inés López Arteaga, full Professor at the Department of Mechanical Engineering and part-time professor at the Royal Institute of Technology (KTH) in Stockholm, within the Marcus Wallenberg Laboratory for Acoustics and Vibration Research. During this visit, supported by the Erasmus + mobility grants programme, Lara del Val gave a talk on Beamforming, as part of the course “Coupled Problems: Vibro Acoustic”, to postgraduate students. This visit laid the foundations for joint work on the use of machine learning techniques, in which Lara del Val has experience, for the detection of faults in vibrating plates, from acoustic images obtained with microphone arrays.
