A mathematical model was developed to monitor and predict changes in salt concentration groundwater a two-layer environment, representing the process of salinization swamping. qualitative analysis scientific research on problem is provided. Since represented by differential equation, effective numerical computational algorithms were solve change based stable disclosure scheme with high-order ac...

NOx concentration is an important indicator of the response to ammonia dosage and nitrogen emissions, its accurate prediction allows for efficient rational optimal control dosage. Due large external noise, time lag non-linearity cement denitrification process, it difficult derive mathematical models. Therefore, a new machine learning model, namely EEMD-MImRMR-BASBP, developed. Firstly, Ensemble...
