Information modeling technology--the open representation of information for database and other computing applications--has grown significantly in recent years as the need for universal systems of information coding has steadily increased. EXPRESS is a particularly successful ISO International Standard language family for object-flavored information modeling. This cogent introduction to EXPRESS provides numerous, detailed examples of the language family''s applicability to a diverse range of endeavors, including mechanical engineering, petroleum exploration, stock exchange asset management, and the human genome project. The book also examines the history, practicalities, and implications of information modeling in general, and considers the vagaries of normal language that necessitate precise communication methods. This first-ever guide to information modeling and EXPRESS offers invaluable advice based on years of practical experience. It will be the introduction that students as well as information and data modeling professionals have been waiting for.

How do you predict the parameters of future solar cycles? What is the role of dynamo theory in the cyclic activity of the Sun and similar stars? And what are the implications of chaos theory for stellar cycles? This book answers these questions and offers a timely review of studies in the cyclic activity of the Sun and other stars. This authoritative reference shows the importance of reliable predictions of the parameters of future solar cycles, and carefully explains the methods currently used to determine these (with special reference to the maximum of cycle 22). Some of the latest research into solar cycles is clearly presented; this includes helioseismology, observations of the extended activity cycle and the polar fields reversal, and contributions from dynamo theory and chaos theory. For graduate students and researchers, this monograph provides a much-needed synthesis of our understanding of activity cycles in the Sun and other stars.
