Papers dealing with the interplay between such techniques will be particularly welcome. Applications papers which emphasize methodology used, implementation and commissioning issues are strongly encouraged. The Journal will also publish tutorial expositions and state-of-the-art reviews. Interested authors for this type of paper should first contact the Editor in Chief and submit an extended summary of approximately 2000 words. The European Journal of Control wishes to encourage (when appropriate) reviewers, editors and authors to participate in discussion sections at the end of published papers. There is no standard format for a discussion section, but its contents should serve to help the readership. For example, views could be expressed on the contribution of the paper in a particular area, its likely impact on industrial practice could be described, or directions for further work suggested. Whatever format the discussion takes, it will be concluded by the author(s). Invitations to participate in the discussion will only be sent out after the paper has been accepted, and all contributors will appear in the issues Table of Contents. Papers from any country in the world are welcome. All submitted papers should be written in English.
