Hello guys .. I need your cooperation... my field is Environmental engineering. I work on treatment of landfill leachate using Fenton. Now I want to maitain ANN (Artificial neural network) on my chapter result. I have some data that got them from lab . the responses include COD, color, TOC, BOD5/COD and heavy metals under these parameters (pH, time, ratio and Fe (II).....the purpose of using ANN is prediction, optimization and having 3D ghtaphs plus those writing . I do not have more time, unfortunetly. Who can help me on this issue ?
