  3. 2. Novel nonlinear multivariate calibration methods

    Författare :Greger Andersson; KTH; []
    Nyckelord :;

    Sammanfattning : The interest fornonlinear modeling has increasedconcomitantly with the increased awareness of the ubiquity ofnonlinear systems. The traditional solution in analyticalchemistry, to linearize the system by some sort of samplepretreatment, is not always an option in process analyticalchemistry. LÄS MER
