Advances in Communications: Volume I of a selection of papers from INFO II, the Second International Conference on Information Sciences and Systems, University of Patras, Greece, July 9–14, 1979

The technical program of the Conference consisted of technical sessions that covered all-important aspects of control, informa­ tion processing/communications, and computers. In particular, there were numerous technical sessions covering all-important aspects of control, such as control theory, control applications, estima­ tion, identification, adaptive systems, linear systems, stability, cybernetics, computational methods, and simulation. The program also included many sessions on information processing/communicati­ ons, such as information theory, coding, signal analysis, signal processing, communication theory, satellite communications, pat­ tern recognition and image processing. Moreover, there were sever­ al sessions on computers, in particular on computer systems, com­ puter communication networks, and automata. Finally, the technical program included numerous sessions on important applications of systems technology, such as power, energy modeling and planning, earth resources, transportation, economics and management, and physiological systems. In view of the broad scope of the Conference technical program and the extensive coverage of many important aspects of systems theory and applications by internationally known researchers, we hope that this collection of papers will be a useful supplement to the published literature and textbooks used for research and teaching. For the success of the Conference we are indebted to a great many people and institutions, primarily to the authors of the papers, without whom the conference would not have existed, and this book would not have materialized. We are particularly indebted to the great majority of them who paid some or all of their own expenses.
