Opis

In the last week of June 1996 the 9th conference of the European Consortium for Math ematics Industry, ECMI 96, took place at the Technical University of Denmark. The present volume of papers is a selection among the almost 200 contributions to the con ference. As a logo on the announcements of the conference the organising committee chose a picture of the connection between Denmark and Sweden which is currently under construction. We chose this picture primarily because of the elegant and decorative lines of the bridge, but for other reasons as well: Denmark is a country of islands, and the art of building bridges has a long tradition here. Danish civil engineers have built bridges all over the world and have been rated among the most competent experts in their field. Many have acted as consultants as well as professors at the Technical University of Denmark, and one of them once said: To build a bridge you need steel and mathematics. We think that this selection of papers with its broad spectrum of industrial top ics proves that the importance of mathematics is continuously growing. Mathematics has penetrated subjects far beyond traditional engineering applications and in more and more places it becomes natural to add mathematics to the list of things you obviously need to succeed.

The use of mathematical models in industry is steadily growing. There is a continuous need in industry for new and efficient mathematical techniques, and university mathematicians get inspiration from industrial demands. The European Consortium for Mathematics in Industry aims to create contact between industry and academia, and to promote research in industrial mathematics. This book contains a broad spectrum of mathematics applied to industrial problems presented at the 1996 ECMI conference in Lyngby/Copenhagen, Denmark. Applied mathematics, case studies, and review papers in the following fields are included: Environmental modelling / Railway systems / Industrial processes / Electronics, circuits, and filters / Ship industry / Oil industry / Optimization in industry / Dynamics of machinery / Fluids in industry Applied mathematicians and other professionals working in academia or industry will find the book to be a useful and inspiring source of mathematical applications related to industrial problems.
