    The energy crisis of 1974 that put many of Britain's electronics companies on a three-day week is now largely forgotten. When memories are pressed, what emerges is that, after all was said and done, productivity during the crisis increased, despite curtailments of the work week and the energy available to do the job. In fact, many recall the crisis with fondness as a difficult challenge met with courage and style. View full abstract»

  • Computers: Computer-based machine-tool control: The best place to inject a computer in numerical control is locally, not as a controller of many systems

    The shift toward the use of computers instead of controller units in NC systems produced both computer numerical control (CNC), in which a self-contained NC system for a single machine tool includes a dedicated computer processor controlled by stored instructions to perform some or all of the basic numerical control functions; and direct numerical control (DNC), which refers to a system of several machine tools directly controlled by a central computer. One of the objectives of CNC and DNC systems is to replace as much of the conventional NC hardware with software as possible, and to simplify the remaining hardware. There are many ways in which functions can be shared between software and hardware in such systems, but all involve some hardware in the controller dedicated to the individual machine.

  • Education: Accreditation: A debatable issue: Key officers of IEEE express diverging views on the role the Institute should play in accrediting electrical engineering programs

    An often-heated debate has raged within IEEE circles for several years over various aspects of accreditation. One major area of concern has been the quality of engineers entering the work force each year. According to many, there has been insufficient attention paid, within IEEE as elsewhere, to the establishment and enforcement of appropriate educational standards in B.E.E. curricula. Further, critics have questioned IEEE's continued endorsement of bachelor of technology programs, suggesting that graduates of such programs are too often accepted by industry as full-fledged EEs. The primary target of such criticisms has been the Engineers Council for Professional Development (ECPD), an umbrella organization that has been the principal arbiter of engineering education standards for nearly 50 years. Its detractors say that ECPD has persisted in stacking its evaluation teams with a predominance of engineering educators who tend to favor relaxed standards. Within IEEE, therefore, there has been an outcry for the Institute to pressure ECPD into reforms of its entire evaluation process ¿ and to withdraw from that body if progress is unsatisfactory.
