    Publication Year: 1978, Page(s): 19
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (409 KB)

    At times it seems the world is populated by two types of folks, systems thinkers and artists. Artists, the theory goes, act only upon instinct, while systems thinkers act logically or not at all. One might suppose that engineers (and physical scientists) are, per se, systems thinkers. Not so. There's a bit of artist in all of us, and some engineers, alas, appear to do their best work in a disorgan... View full abstract»

    Discusses the influence of decreasing hardware costs on future development of CAI projects. The developments of suitable courseware are dealt with, outlining three main categories of authoring concepts (pre-guessed student responses, discovery-oriented approach and an approach by which the student becomes a learning strategist). Some of the major CAI development centres are surveyed and results ac... View full abstract»

  • Consumer electronics: Helping speeders beat the radar rap: Moving radar and dual-band detectors constitute a miniature ECM race between enforcement-minded authorities and motoring outlaws

    Describes the development of radar detectors which provide the motorist with an advance warning that speed traps or moving radar are operating nearby. The key components in the radar detectors are the microwave diodes. Two types of radar design-the passive radar detector and the heterodyne detector are described. Legal implications of these devices are discussed. View full abstract»

    The following five steps for evaluating power system reliability are examined: defining system failure modes; analysis of events leading to failure; modelling system failures; determining reliability parameters; and applying reliability evaluation, e.g. for determining the required reserve generating capacity.

    Describes Worcester Polytechnic Institute's nontraditional approach to education. It is based on self-initiated study, terminal accountability, and undergraduate projects-rather than courses-as the heart of the learning experience. The school has only four academic requirements for graduation-three projects, and competency examination. View full abstract»

  • New product applications: High-speed wide-band FET-input op amp operates from a single positive supply

    Publication Year: 1978, Page(s):69 - 74h
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (7399 KB)

    This high-speed FET-input wide-band operational amplifier may be operated from a single positive power supply with the inputs at ground potential. The input common-mode voltage includes the negative power supply voltage. Output-voltage swing is within 300 mV of the power-supply rail voltages, for full-load conditions. It is within 50 mV of the power-supply rail voltages for small low-current loads... View full abstract»
