Two types of contributed papers are invited: Regular papers, describing completed work in some detail, and Short papers, presenting recent, perhaps preliminary results. Papers will be accepted on the basis of abstracts (at least page and and at most two pages) which should be sent by June 10, 1989 to The 21st SSS Secretariat, Division of Control Sciences, Dept. of Mechanical and System Engineering, Kyoto Institute of Technology, Matsugasaki, Sakyo-ku, Kyoto 606, Japan. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by A.

Willems, Zandsteenlaan 16, 9743 TN GRONINGEN, The Netherlands. Manuscripts should be written in English, typed double spaced with wide margins, and on one side of the page only. Manuscripts should not exceed 3600 words, subtracting space needed for figures and tables. This comes to about 12 double-spaced typewritten pages. The papers will be reviewed by the editorial board. The managing editor will advise the authors on the acceptance of their paper in principle within six weeks after receiving the manuscript. The publisher will strive to obtain a delay of at most three months after acceptance of the paper. There are no page charges and authors will receive 40 reprints free of charge. More reprints may be ordered against payment. Stylistic instructions for preparation of manuscripts: On the first page of the manuscript the author should provide a title, name and complete address for correspondence (not as a footnote), a self-contained abstract without formulas, and, below the abstract, at least five keywords. Formulas should be typed, with special symbols possibly handwritten. The author should include a list explaining all symbols which are unusual or not typewritten. Awkward mathematical notation which require special typesetting procedures should be avoided. The numbers identifying displayed mathematical expressions should be placed in parentheses at the right margin. Part of text should not be subject to this numbering. Good quality originally drawn figures should be provided upon submission of the manuscript on separate pages in a form suitable for photographic reproduction. Figures should be numbered consecutively, not by section number, and referred to in the text by number. References should be given as explained on the inside of the back cover of the journal. SUBSCRIPTION INFORMATION SYSTEMS & CONTROL Letters (ISSN 0167-6911) is published in two volumes of five issues a year. The subsription price for 1989 (comprising volumes 12 & 13) is Dfl. 530 + Dfl. 54 for postage and handling. Mail orders and inquiries to: Elsevier Science Publishers B.V., Journals Department, P.O.
