High yields and environmental control in crop farming call for precise adaptations to local growing conditions. Treating large fields in a uniform way by high capacity machinery cannot be regarded as a sustainable method for many situations. Because differences existing within single fields must be considered. The transition from former field work carried out manually or by small implements to present-day high-capacity machinery caused that the farmers lost the immediate and close contact with soils and crops. However, modern sensing and controlling technology can make up for this deficit. High tech methods that include proximal sensing and signals from satellites can provide for controls that allow adjusting farming operations to small fractions of one ha and sometimes even down to some m2, hence in a site-specific mode. This applies to operations for soil cultivation, sowing, fertilizing and plant protection. This book deals with site-specific concepts, applications and results.

Peter A. Coming Palo Alto, CA November, 2000 This volwne represents a distillation of the plenary sessions at a unique millenniwn year event -a World Congress of the Systems Sciences in conjunction with the 44th annual meeting of the International Society for the Systems Sciences (ISSS). The overall theme of the conference was "Understanding Complexity in the New Millenniwn. " Held at Ryerson Polytechnic University in Toronto, Canada, from July 16-22,2000, the conference included some 350 participants from over 30 countries, many of whom were representatives of the 21 organizations and groups that co-hosted this landmark event. Each of these co-host organizations/groups also presented a segment of the program, including a plenary speech. In addition, the conference featured a nwnber of distinguished "keynote" speeches related to the three daily World Congress themes: (1) The Evolution of Complex Systems, (2) The Dynamics of Complex Systems, and (3) Human Systems in the 21st Century. There were also seven special plenary-level symposia on a range of timely topics, including: "The Art and Science of Forecasting in the Age of Global Wanning"; "Capitalism in the New Millenniwn: The Challenge of Sustainability"; "The Future of the Systems Sciences"; "Global Issues in the New Millenniwn"; "Resources and the Environment in the New Millenniwn"; "The Lessons of Y2K"; and "Can There be a Reconciliation Between Science and Religion?" Included in this special commemorative volume is a cross-section of these presentations.

Goals of the Book Overthelast thirty yearsthere has been arevolutionindiagnostic radiology as a result oftheemergenceofcomputerized tomography (CT), which is the process of obtaining the density distribution within the human body from multiple x-ray projections. Since an enormous variety of possible density values may occur in the body, a large number of projections are necessary to ensure the accurate reconstruction oftheir distribution. There are other situations in which we desire to reconstruct an object from its projections, but in which we know that the object to be recon structed has only a small number of possible values. For example, a large fraction of objects scanned in industrial CT (for the purpose of nonde structive testing or reverse engineering) are made of a single material and so the ideal reconstruction should contain only two values: zero for air and the value associated with the material composing the object. Similar as sumptions may even be made for some specific medical applications; for example, in angiography ofthe heart chambers the value is either zero (in dicating the absence of dye) or the value associated with the dye in the chamber. Another example arises in the electron microscopy of biological macromolecules, where we may assume that the object to be reconstructed is composed of ice, protein, and RNA. One can also apply electron mi croscopy to determine the presenceor absence ofatoms in crystallinestruc tures, which is again a two-valued situation.

Published to coincide with the First Guangzhou Triennial (opening November 18, 2002), this volume provides a systematic description and analysis of Chinese experimental art and cinema of the 90s, the subject of the Triennial. This volume consists of three parts: Part One provides an overview of 90s' Chinese cinema with seventeen scholarly essays on Chinese cinema and experimental art; Part Two is a catalogue of 130 works by 120 artists selected for the Triennial and provides an analysis in three large thematic sections centered on "History and Reality, " "People and Environment, " and "Local and Global"; Part Three provides a complete chronology of important events and exhibitions and a detailed bibliography, including all publicly and privately published books and exhibition catalogue of this art.
