The second edition of Space Mission Analysis and Design continues the tradition of emphasizing the process of mission design established by the first edition. Process tables are now included for all elements of the design activity. The quick-reference tables of important mission design parameters have been expanded to six pages on the inside rear cover. Numerous data tables have been expanded and updated, including space computers and a new presentation of satellite lifetimes. New sections have been added on defining the overall mission concept, subject trades, guidance and navigation, and applying the mission analysis and design process to reduce cost and risk in later programme stages. The material on mission analysis, space payloads, spacecraft subsystems, and launch systems has been substantially revised. This book remains an invaluable tool for the concept exploration process and is required reading for anyone involved in this process for unmanned space missions.

This text contains the papers and posters presented at the Eucarpia Fruit Breeding Section Meeting held at Wadenswil/Einsiedeln, Switzerland from August 30 to September 3, 1993. It gives an overview of the latest trends in temperate fruit breeding in Europe and overseas. Three subjects were considered in special workshops: durability of scab resistance in apple, biotechnology and molecular markers. One important aim of modern fruit breeding is stable resistance to pests and diseases. Molecular markers might help to identify the genetic basis of important characters related to disease and pest resistance and components of yield and quality. Gene transfer has been successfully applied in several fruit species. However, public opinion in many countries does not favour this new technology and its products. Despite these new approaches, traditional breeding methods still predominate; many aspects of traditional breeding are considered in this book.

International Seaweed Symposia have been held at three-year intervals for nearly 50 years. In the early days they formed the only international forum for marine phycologists, and although there are now frequent phycological meetings their value has not diminished, both because of the increased commercial importance of seaweeds, and because of the unique mix of disciplines that the meetings attract. Industrialists interact with chemists and biologists with the common aim of understanding seaweeds. The main development during the last few decades has been an increase in the cultivation of algae, as natural stocks of the useful species become depleted. Of the first ten Symposia, nine were held in western countries where seaweed cultivation is almost non-existent. It is appropriate that the last two have been held where algal exploitation is relatively big business.

Modal analysis is one of the most powerful tools available to the engineer for the dynamic analysis of structures. Development has been rapid and spans the identification and evaluation of vibration phenomena, the validation, correction and updating of analytical models and the assessment of structural integrity.

Is the climate warming? Is the hydrological cycle intensifying? Is the climate becoming more variable or extreme? Is the chemical composition of the atmosphere changing? Is the solar irradiance constant? Answers to these questions are fundamental to understanding, predicting, and assessing climate on time scales ranging from weeks to a century. Atmospheric, oceanic, and environmental scientists have primarily relied on an ad-hoc collection of disparate environmental observational and data management systems to address these problems. But these systems were not designed to measure climate variations and, as a result, changes and variations of the earth system during the instrumental climate record is far from unequivocal. This study develops a framework from which a Global Climate Observing System (GCOS), currently being discussed in international forums, can be implemented to monitor changes and variations of climate.

Design has become and important research topic in engineering and architecture. It is one of the keystones to economic competitiveness and the fundamental precursor to manufacturing. The development of computational models founded on the artificial intelligence paradigm has provided an impetus for current design research.

While information on recent microbial mats and precambrian stromatolites can be found in numerous publications, this book presents essential information on phanerozoic stromatolites, which have not yet received very much attention. Emphasis is placed on freshwater environments and deep-marine settings, and phosphatic stromatolites.

Since the establishment of the CAAD futures Foundation in 1985 CAAD experts from all over the world meet every two years to present and at the same time document the state of art of research in Computer Aided Architectural Design. The history of CAAD futures started in the Netherlands at the Technical Universities of Eindhoven and Delft, where the CAAD futures Foundation came into being. Then CAAD futures crossed the oceans for the first time, the third CAAD futures in 1989 was held at Harvard University. Next stations in the evolution were in 1991 Swiss Federal Institute of Technology, the ETC, Zurich. In 1993 the conference was organized by Carnegie Mellon University, Pittsburgh and in 1995 by National University, Singapore, CAAD futures 1995 marked the world wide nature by organizing it for the first time in Asia.

Hydroxybenzophenones are most useful synthetic intermediates in the chemical industry, for example in pharmaceuticals, dyes, fragrances, agrochemicals, explosives and plastics. In this handbook, the diverse methods of obtaining over 1900 hydroxybenzophenones are described, and their physico-chemical properties and spectroscopic data references are indicated. Hence, ketones are classified methodically. They are thus easily accessible from three tables - the molecular formula index, the chemical abstracts registry numbers, and the usual names index. This work should prove to be a valuable tool for laboratory work and research and development departments. This handbook is particularly intended for engineers in chemical synthesis and academic as well as industrial researchers from various branches of chemistry.

The Second International Food Legume Research Conference (IFLRC-II) was held from 12-16 April 1992 in Cairo, Egypt. Five cool season food legume crops were included in the deliberations: pea (Pisum sativum), lentil (Lens culinaris), faba bean (Vicia faba), chickpea (Cicer arietinum) and grasspea (Lathyrus sativus).

Computer simulations and modelling are used frequently in science and engineering, in applications ranging from the understanding of natural and artificial phenomena to the design, test and manufacturing stages of production. This widespread use necessarily implies that a detailed knowledge of the limitations of computer simulations is required. In particular, the usefulness of a computer simulation is directly dependent on the user's knowledge of the uncertainty in the simulation. Typical limitations of computer simulations include uncertainty in the data, parameter uncertainty, errors in the initial data, modelling errors, unmodelled phenomena, reduced order models, and approximations and numerical errors.

The exploitation of new, advanced structures and electromechanical systems has been one of the mainstream research and development activities in recent years. In the search for and research into innovative technologies, piezoelectric materials are proved to be very versatile in both sensor and actuator applications. Consequently piezoelectric technology has been widely applied to a large number of industrial applications and devices, varying from thin-film microsensors/actuators to large space structures, in addition to relatively conventional applications, eg sensors, actuators, mobile robots, micromotors, etc.

Concentrations of greenhouse gases in the atmosphere have been increasing since the Industrial Revolution, prompting concern that these increases could result in global and regional climate change. The impacts of this enhanced greenhouse effect are not yet fully understood and may depend on both the degree and the speed of climate change.

The fine arts first emerged divided by the five senses yet, since their very origin, they have projected aesthetic networks among themselves. Music, song, painting, architecture, sculpture, theatre, dance - distinct in themselves - grew together, enhancing each other. In the present outburst of technical ingeniosity, individual arts cross all barriers, as well as proliferate in kind. Hence the traditional criteria of appreciation and enjoyment vanish. The enlarged and ever-growing field calls for new principles of appreciation and new values, essential to our culture. This collection initiates an inquiry into the aesthetic foundations of the fine arts. Their common aesthetic nature, as well as the differentiating specificities which sustain them, might reveal the universal role of aesthetics in human life.

The increasingly competitive environment within which modern industry has to work means that processes have to be operated over a wider range of conditions in order to meet constantly changing performance targets. Add to this the fact that many industrial operations are nonlinear, and the need for on-line control algorithms for nonlinear processes becomes clear. Major progress has been booked in constrained model-based control and important issues of nonlinear process control have been solved. This text surveys the state-of-the-art in nonlinear model-based control technology, by writers who have actually created the scientific profile. A broad range of issues are covered in depth, from traditional nonlinear approaches to nonlinear model predictive control, from nonlinear process identification and state estimation to control-integrated design. Advances in the control of inverse response and unstable processes are presented. Comparisons with linear control are given, and case studies are used for illustration.
