In order to meet the new stringent environmental regulations, it is necessary to investigate the adaptive and optimal control strategies for the biological wastewater treatment processes. Nitrogen removal is one of the essential concerns in wastewater treatment. Nitrogen removal is a nonlinear, dynamic, and time variant complex process as complicated activities of microbial metabolism are invol...

This work presents a novel approach for the accurate estimation of multiple time-delays from frequency response distributed system. The proposed is based on powerful and flexible machine learning technique, namely, least-square support vector (LS-SVM). LS-SVM regression used to construct metamodel transfer function describing generic linear time-invariant system in delayed-rational form. Specif...
