    From time to time I have decried the absence of engineers on contemporary lists of heroes. We find plenty of pop singers and politicians, a few religious leaders, and an occasional sports hero. View full abstract»

  • Optical computing: A field in flux

    Publication Year: 1986, Page(s):34 - 38
    Cited by:  Papers (2)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1918 KB)

    The growth and development of the optical computing field is reviewed. The range of aspects explored includes the best materials for electrooptic devices, the circuits that can be built from those devices, the computer architectures that can incorporate those components, and the algorithms that can be run on machines configured for light beams instead of electronic signals. The author considers hy... View full abstract»

  • Photons in the service of electrons

    “Electronics can make a 10-picosecond transistor, but it's very difficult to make a 10-picosecond wire,” remarked AT&T's Alan Huang. Not surprisingly, all investigators want to capitalize on the superiority of photons to electronics in handling communications and interconnections. View full abstract»

    Optical processors operated by the US. Department of Defense can perform calculations that would defeat a collection of the fastest Crays. “Yet the optical processors are solving real-world problems,” said one engineer, “Crays can solve them, but not fast enough. The solution is needed on the fly, not over the weekend.” View full abstract»

    “Computers are now at a midlife crisis,” said Alan Huang of AT&T Bell Laboratories. “Beyond 1 picosecond you begin dealing with optical frequencies anyway. So either you ignore the fact that it's optical frequencies or you make use of that fact. I am a digital computer person; most of the computers I've designed are electronic. Now I'm trying to move computers into a different technology that ... View full abstract»

    'A five-year-old child can recognize faces, but a super Cray can't even recognize a handwritten character,' remarked Demetri Psaltis, associate professor of electrical engineering at the California Institute of Technology in Pasadena. Yet a human being is lousy at algebra compared with a computer. What is it about a digital electronic computer that makes it so awkward for certain tasks versus the ... View full abstract»

    Digital coding techniques are described that promise to enhance the applicability of voice communications and storage. The techniques allow more speech to be represented with a given number of binary digits, without losing natural voice quality. The advanced coding techniques just becoming available yield natural-sounding telephone speech at digital transmission rates of 16, 8, and eventually 4 Kb... View full abstract»

  • Burning coal more cleanly and efficiently: Faced with tougher antipollution laws and inflationary costs, electric utilities turn to advanced coal combustion technologies

    Publication Year: 1986, Page(s):64 - 69
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (2241 KB)

    In the context of tougher antipollution laws and inflationary costs for electric utilities, advanced coal combustion technologies are discussed. The new technologies promise better pollution control at lower cost than attempts to patch the old systems; they also solve the utility problem of how to add small increments of generating capacity in only a few years. The discussion emphasizes fluidized-... View full abstract»
