• Model updating of wind turbine blade cross sections with invertible neural networks 

  Noever-Castelos, Pablo; Ardizzone, Lynton; Balzani, Claudio (Chichester : Wiley, 2021)

  Fabricated wind turbine blades have unavoidable deviations from their designs due to imperfections in the manufacturing processes. Model updating is a common approach to enhance model predictions and therefore improve the ...
