    The work of Sohie and Maracas (ibid., vol.86, no.12, p.1616-18, Dec. 1988) concerned the representation of a decaying time function by a weighted sum of exponentials. It is shown that the problem can be solved in greater generality and in a more straightforward manner by using classical vector-space methods. The classical vector-space analysis is specialized to a particular function space containi... View full abstract»

    The author notes that workspace design requirements for air traffic control man-machine interfaces (MMIs) are generally orthodox, although the MMI must remain efficient throughout gross changes in staffing levels. Decisions during the MMI design largely determine how it can be used and what the controller must know about it. It is emphasized that human factor consequences should be considered when...
