    To anticipate technological progress, one tool often used by company strategists is the technology s-curve. Proposed about a quarter of a century ago by Richard Foster, the s-curve is based on a fairly straightforward concept. It tracks the progress of a base technology as a function of the R&D effort or, if R&D is constant, of time. The s-curve has been used in plotting technologies as diverse as... View full abstract»

    This article provides a description of the hostile environment that satellites and spacecraft are exposed to as they travel through the ionosphere and magnetosphere. As this environment changes continually there is a need to be able to predict its future status. Such prediction efforts concentrate on the Sun and solar wind which drives the near Earth environment. Geomagnetic storms are additional ... View full abstract»

    The integrated-services digital network, for 10 years seen only in limited installations, is branching out around the world. The author describes how telephone carriers are now starting to report a big boost in ISDN installations. He details how the surge is the result of an increasing appetite for bandwidth, a broadening suite of ISDN-enabled applications, wider availability of the network's serv... View full abstract»

    A multitude of outspoken critics disputed the theory of fuzzy logic, developed by Lotfi A. Zadeh in the mid-1960s. Some 20 years were to pass before the theory became widely accepted-capped by the 1995 award of the IEEE Medal of Honor to Zadeh “for pioneering development of fuzzy logic and its many diverse applications”. Even today some critics remain. But Zadeh never wavered. He had f... View full abstract»
