    Discusses the Harpy experimental system using a low-cost minicomputer which is capable of automatic speech recognition with up to 98% accuracy when the vocabulary is restricted to 1011 words, and sentence structure limited to that used in the retrieval of abstracts of documents relating to computer technology. The recognition process of the system is described. View full abstract»

    Space is infinite; yet the space in Earth's orbit is finite, and collisions in space between man-launched objects have become a threat. As the number and size of orbiting space stations continue to grow, there is increasing danger that they will hit some fragment of “junk” — spent rockets, dead payloads, fragments from explosions and collisions in space, and the like. This “junk” could threaten sm... View full abstract»

    In the fierce competition that shook the semiconductor industry in the 1950s, transistor and diode prices tumbled, along with more than a few managerial heads, as company after company discovered the importance of the learning curve. What this taught basically was this: As a manufacturer gains experience in making a product, he should be able to produce it more “cleverly,” more efficiently and in ... View full abstract»
