If you have knowledge on this topic, please tell me where I can find out detailed information. Thanks for your time.

The symposium will cover a broad range of topics relevant to the field of mathematical modelling in science. These topics will include the following: * Mathematical modelling and simulation in science and technology * Computational methods for the solution of corresponding model problems * Methods of numerical algebra and analysis * Expert systems in science * Visualization techniques for pre- and post-processing The MODELLING 94 programme will include invited lectures, short communications and posters. Papers presented at the symposium will be published in the Proceedings. For further information, please contact Organizing Committee - Modelling 94, J.
