  • Spectral Lines: Education: Good news and bad

    In response to ¿crisis¿ labels that had been attached to engineering education in the United States five or six years ago, the National Research Council undertook a study lasting some two years. Its report was released in May 1985. Entitled ¿Engineering Education and Practice in the United States,¿ it dealt with undergraduate education, graduate education and research, continuing education, an... View full abstract»

  • HVDC: Wheeling lots of power: Moving power from where it is plentiful to where it is needed may be more efficient than building oil-fired or nuclear plants locally

    Publication Year: 1985, Page(s):30 - 36
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5334 KB)

    HVDC systems can transmit more power from electricity-rich areas over longer distances than alternating-current lines of equivalent cost. It is pointed out that one advantage of direct-current transmission is its inherent immunity to the inductive reactance problems that make it difficult to use alternating current when long lines and large loads are involved. Direct-current cables can also carry ... View full abstract»

  • The DIP may take its final bows: The dual-in-line package, the reigning IC package for several generations, is losing position to newcomers for packaging advanced chips

    As the number of leads, or pins, on the dual-in-line package (DIP) increases, its size increases rapidly. DIPs are becoming up to 50 times bigger than the chips themselves, thus defeating the gains of miniaturization resulting from IC advances. A pin-grid array package with leads protruding from the bottom, can handle 256 leads in an area of about 3 square inches. New packages that are becoming av... View full abstract»

  • Laser diodes are power-packed: Single-mode laser diodes have a rosy future, both as individual sources of power up to 100 milliwatts and in arrays promising up to half a watt

    The ultimate power limits of current diode-laser structures are considered, along with the prospects of new applications. After explaining how the physical geometry of a diode laser determines its performance, the author discusses the three methods that can relax the output-power limits imposed by the gradual or catastrophic degradation of the diode's mirror facets. Attention is given to ways of o... View full abstract»

  • The X-29: is it coming or going?

    Publication Year: 1985, Page(s):54 - 63

    The X-29 is an experimental aircraft built by the Grumman Aerospace Corp. for the US Defense Research Projects Agency. Relaxed static stability, one of the aircraft's key design features, means that the pilot must depend exclusively on computers to fly the plane. The X-29's computers monitor and adjust the positions of the plane's control surfaces every 25 milliseconds to follow the pilot's direct... View full abstract»

  • The friendly fields of RF: Encouraged by successes in fusing fractured bones, researchers look to electromagnetic fields for healing wounds and shrinking tumors

    Publication Year: 1985, Page(s):64 - 69
    Cited by:  Papers (1)

    RF fields affect biological systems in two principal ways: by generating heat (relatively strong fields) and by nonthermal mechanisms (weaker fields). The latter are used for bone healing. Treatment of congenial pseudoarthrosis of the tibia by pulsed electromagnetic fields has produced recovery rates exceeding 75%. Experiments on animals have shown that osteoporosis can be reversed by pulsed elect... View full abstract»

  • Planning a probing voyage to Jupiter: The adroit Galileo spacecraft, crammed with advanced instrumentation, should answer some age-old questions about the mysterious planet

    Publication Year: 1985, Page(s):70 - 76
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4204 KB)

    The design of the Galileo spacecraft is described. To accommodate the instruments that require continuous scanning as well as those that need accurate pointing, the orbiter will have two sections, one spinning and the other stationary. A brief summary is given of the mission's scientific goals. The tasks that will be performed by the spacecraft's command and data subsystem and attitude and articul... View full abstract»
