Spacecraft Power Technologies is the first comprehensive text devoted to the technologies critical to the development of spacecraft electrical power systems. The science and engineering of solar, chemical, and nuclear systems are fully examined together with the constraints imposed by the space and thermal environments in which the systems must operate. Details of present technology and the history that led to the current state-of-the-art are presented at a level appropriate for the student as a textbook or the practicing engineer as a reference.

A North Atlantic Treaty Organization (NATO) Advanced Studies Institute (AS I) on Defense Conversion Strategies was held at the Atholl Palace Hotel, Pitlochry, Perthshire, Scotland, from July 2 through July 14, 1995. This publication is the proceedings of the Institute. The NATO Advanced Studies Institute program of the NATO Science Committee is a unique and valuable forum under whose auspices over one thousand international tutorial meetings have been held since the inception of the program in 1959. The ASI is intended to be primarily a high-level teaching activity at which a carefully defined subject is presented in a systematic and coherently structured program. The subject is treated in considerable depth by lecturers eminent in their fields and of international standing. The subject is presented to other experts or practitioners who will already have specialized in the field or possess an advanced general background appropriate to the topic. The ASI is aimed at an audience at the post-doctoral level. This does not exclude advanced graduate students or other senior participants with qualifications and achievements in the subject of the ASI or rclated areas. This ASI was prompted by several events in the defense environment.

For some time, all branches of the military have used a wide range of sensors to provide data for many purposes, including surveillance, reconnoitring, target detection and battle damage assessment. Many nations have also attempted to utilise these sensors for civilian applications, such as crop monitoring, agricultural disease tracking, environmental diagnostics, cartography, ocean temperature profiling, urban planning, and the characterisation of the Ozone Hole above Antarctica. The recent convergence of several important technologies has made possible new, advanced, high performance, sensor based applications relying on the near-simultaneous fusion of data from an ensemble of different types of sensors. The book examines the underlying principles of sensor operation and data fusion, the techniques and technologies that enable the process, including the operation of 'fusion engines'. Fundamental theory and the enabling technologies of data fusion are presented in a systematic and accessible manner. Applications are discussed in the areas of medicine, meteorology, BDA and targeting, transportation, cartography, the environment, agriculture, and manufacturing and process control.

The world situation has witnessed dramatic changes in the recent past and defense-related science and technology are coming under increasing pressure to demonstrate their ability to contribute added value to national and international economies. But defense conversion is complicated by the absence of tested principles and there is no formal training to facilitate the conversion process. As a result, such factors as long-term implications for defense together with a broad range of issues related to economic, political and social questions are not being adequately addressed. Governments and industries are searching for optimum strategies to guide the defense conversion process without benefit of either historical precedents as models or a complete understanding of the process itself. The present book identifies and studies the elements of successful defense conversion strategies through a systematic analysis of the factors influencing them and the common features of specific national efforts. The book reflects a combination of theory and practical experience. International strategies are explored that stimulate the conversion of defense technologies to industrial capacity, global economic growth and stability, the preservation and enhancement of defense technology options, and the ability to capitalize on unique economic, political and social opportunities afforded by defense technology conversion. The nations of the former Soviet Union present a particular problem. In Russia, for instance, from 1990 to 1993 there was a 47% decline in industrial production and a 38% decrease in GNP. This clearly needs immediate action, but there are difficulties with the conversion processes, technologytransfer and implementation of dual-use strategies. While many of these issues are generic to the process, there are national and cultural difficulties. At a time of unprecedented global political and economic instability, the collective knowledge and experience of NATO and its Cooperation Partners will be essential to the successful conversion of defense production capabilities to economic tools that can contribute to universal economic equilibrium and prosperity.

A NATO Advanced Study Institute (ASI) on the Behavior of Systems in the Space Environment was held at the Atholl Palace Hotel, Pitlochry, Perthshire, Scotland, from July 7 through July 19, 1991. This publication is the Proceedings of the Institute. The NATO Advanced Study Institute Program of the NATO Science Committee is a unique and valuable forum, under whose auspices almost one thousand international tutorial meetings have been held since the inception of the program in 1959. The ASI is intended to be primarily a high-level teaching activity at which a carefully defined subject is presented in a systematic and coherently structured program. The subject is treated in considerable depth by lecturers eminent; in their :(ield and of international standing. The subject is presented to other scientists who either will already have specialized in the field or possess an advanced general background. The ASI is aimed at approximately the post-doctoral level. This ASI emphasized the basic physics of the space environment and the engineering aspects of the environment's interactions with spacecraft.
