PERFORMANCE ANALYSIS OF CULTURALLY OPTIMIZED WAVELET LIFTING SCHEME IN CORROSION DATA FILTERING
Pasquale Arpaia, Carmine Romanucci, Antonio Zanesco
Abstract:
The optimal design of an adaptive wavelet filter based on lifting scheme by means of evolutionary cultural algorithms is proposed, with the aim of filtering data for dynamic corrosion monitoring. First, in corrosion rate measurement through electrochemical impedance spectroscopy, the problem of uncertainty due to noise arising from underground disturbances in buried structures is stated. Then, the proposed adaptive filtering procedure is illustrated. Finally, the results of the experimental validation on two different corrosion case studies are highlighted.
