Welcome to Aachen and to the First European Simulation Congress ESC83, a triennial international conference jointly promoted by ASIM/GI, DBSS, SIMS and UKSC. ESC83 is organized by ASIM/GI,. supported by SCS and IMACS, and sponsored by NGI (section for simulation). It takes place at the Karman Auditorium of the Aachen Technical Univer­ sity, FRG. The aim of ESC83 is to cover all aspects of modeling and simulation in theory and practice, to promote the exchange of knowlewdge and experience between different international research groups in this field, and to strengthen the international contact between developers and users of modeling and simulation techniques. On the occasion of the Congress people of scientific and engineering disciplines will meet to discuss the state of the art and future activities and developments. A large number of contributed papers has been strictly examined and selected by the Scientific Committee to guarantee a high international standard. The book contains the accepted papers that will be presented at the Congress. The papers have been classified according to the following keywords.

Das seit 1975 im ein- bis dreijährigen Turnus ausgerichtete "Aachener Symposium für Signaltheorie" - früher "Aachener Kolloquium" - widmet sich schwerpunktmäßig den theoretischen Grundlagen der Signalverarbeitung. Es erlangt dadurch eine besondere Bedeutung, daß die Bezüge zur Anwendung und Technologie integraler Bestandteil dieser Veranstaltung sind. Die diesjährige Tagung wurde unter dem Thema "Modellgestützte Signalverarbeitung" durchgeführt. Themenschwerpunkte bildeten dabei die modellgestützte Verarbeitung, Modelle, Algorithmen und Architekturen. Diese Themenwahl trägt insgesamt der Tatsache Rechnung, daß in zunehmend aufwendigeren Signalverarbeitungsprozessen die zugrundeliegenden abstrakten Verarbeitungsmodelle, deren theoretische Behandlung und Implementierung einer auf vielen Sichtweisen beruhenden Strukturierung bedürfen. Der vorliegende Tagungsband repräsentiert nicht nur aktuelle Ergebnisse zu speziellen Forschungsgebieten, sondern stellt zugleich eine Plattform für die Verständigung der involvierten Fachrichtungen (Ingenieurwissenschaften, Mathematik, Informatik, Physik, Biologie etc.) untereinander dar.
