The 1990 CIME course on Mathematical Modelling of Industrial Processes set out to illustrate some advances in questions of industrial mathematics, for example the application of mathematics to real-life problems. The papers contained in this volume describe the genesis of the models and illustrate their relevant mathematical characteristics. Among the themes dealt with are thermally controlled crystal growth, thermal behaviour of a high-pressure gas-discharge lamp, the sessile-drop problem, etching processes, the batch-coil-annealing process, inverse problems in classical dynamics, image representation and dynamical systems, scintillation in rear projections screens, identification of semiconductor properties, and pattern recognition with neural networks.
