This article applies the standard deviation of partial signal (SDPS) plots of electrochemical noise (EN) current signals originating from corrosion events on the symmetrical and asymmetrical electrodes made of uncoated and polypyrrole (PPy)-coated mild steel alloy in 4000 ppm NaCl+1000 ppm NaNO2 solution. Signal recording was performed after 30, 60, 90 min and 24 h from immersion...

The idea of using Feed-Forward Neural Networks (FFNNs) as regression functions for Nonlinear AutoRegressive eXogenous (NARX) models, leading to models herein named NARXs (NNARXs), has been quite popular in the early days machine learning applied nonlinear system identification, owing their simple structure and ease application control design. Nonetheless, few theoretical results are available c...
