    The principal suspects in the Jan. 28 shuttle accident, as we write, are the gaskets, or O-rings, intended as the ultimate seal between segments of the solid rocket motors. Their potentiality for failure had been well known; their deterioration during previous missions had been well documented; and numerous alternate designs had been proposed. View full abstract»

    Beneath a stretch of mesas and bone-dry lake beds some 100 miles north of Las Vegas, Nev., at least 16 nuclear warheads were detonated last year, releasing enough energy to destroy a dozen major cities. Since 1951 the United States has exploded more than 680 bombs above and below this landscape, broken only by clumps of sagebrush, scraggy grass, and craters. View full abstract»

  • The compact disk ROM: How it works: An offshoot of the compact digital audio disk, this multimegabyte storage technique is revolutionizing database technology

    Publication Year: 1986, Page(s):43 - 49
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (2541 KB)

    A description is given of the CD-ROM, or compact-disk read-only memory, which is an offshoot of the highly successful digital compact disk (CD) used for audio recording. It is a permanent optical digital storage device that, in conjunction with an associated drive, becomes a powerful peripheral for the personal computer. The disk puts multimegabyte permanently stored databases at the user's finger... View full abstract»

    The prime software goal is to create data structures and accessing strategies optimized for the drive's characteristics. Economic concerns arise at each stage of the process, with one-time costs predominating on the data preparation and mastering side, and unit costs on the production and retrieval side. The problem of the slow access speed of CD-ROMs is discussed. The possibilities afforded by CD... View full abstract»

    The description is given of the Manufacturing Automation Protocol (MAP), a set of communication protocols based on a bus configuration, in which network stations are wired together with a common bus so all can receive all messages. Any station, when sending a message, designates in the address portion of that message where it should go. All other stations receive the transmitted message and examin... View full abstract»

    The Technical and Office Protocols, or TOP, specification addresses the communications problem for engineering and general office applications. Ultimately, TOP is expected to provide common communications methods and related services for the exchange of information in a variety of applications, including electronic mail, word processing, file transfer, graphics, database management, and business a...

  • The promise of the Kalina cycle: Using an ammonia-water mixture, the Kalina steam cycle may permit thermal-mechanical-electrical energy conversion efficiencies of 45 percent

    Publication Year: 1986, Page(s):68 - 70
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1118 KB)

    The principles of the Kalina cycle are described. In theory, the Kalina cycle can help convert approximately 45% of a direct-fired system's heat input to electricity and up to 52% for a combined-cycle plant (a gas turbine produces exhaust, which enables a steam turbine to produce electricity). This compares with about 35% and 44%, respectively, for the steam cycle. Plans announced by the Fayette M... View full abstract»

  • A surge for solid state: Revitalization of the U.S. semiconductor industry may depend on supplying unconnected transistors and letting the buyer specify on-chip interconnections

    The author maintains that the question of who will specify and design the chip system is at the heart of the major restructuring taking place within the semiconductor industry. If users specify how the foundry should connect transistors, semiconductor manufacturers can return to supplying chips on a more stable basis. After discussing the competitive challenge posed by Japan the author considers t... View full abstract»

    The work being done by the Semiconductor Research Corp. (SRC) in promoting university research, funding the training of graduate students, and fostering cooperation between companies is reviewed. It is pointed out that not only are more researchers working in the semiconductor field, but their work is now more closely related to industry needs. Some of the technological advances that have been mad... View full abstract»
