Szukana fraza: [Abstract = "In this paper an overview is given of issues in parameter estimation, model discrimination, and optimal sensor selection as they relate to the modelling of copolymerization processes. The problems are discussed in the context of a comprehensive polymerization simulation package that is being developed, which includes an extensive database. A brief description of the modelling equations together with a listing of equations used to predict copolymer composition, triad fractions and polymerization rate, which are the primary responses used throughout this paper, is given."]
