    • Stepping Motor Control System 

      Larson, Noble G. (MIT Artificial Intelligence Laboratory, 1979-02)
      This paper describes a hardware system designed to facilitate position and velocity control of a group of eight stepping motors using a PDP-11. The system includes motor driver cards and other interface cards in addition ...
    • Specifying and Proving Properties of Guardians for Distributed Systems 

      Hewitt, Carl; Attardi, Giuseppe; Lieberman, Henry (MIT Artificial Intelligence Laboratory, 1979-05)
      In a distributed system where many processors are connected by a network and communicate using message passing, many users can be allowed to access the same facilities. A public utility is usually an expensive or limited ...
    • Looking in the Shadows 

      Woodham, Robert J.; Horn, Berthold K.P. (MIT Artificial Intelligence Laboratory, 1976-05)
      The registration of an image with a model of the surface being imaged is an important prerequisite to many image understanding tasks. Once registration is achieved, new image analysis techniques can be explored. One approach ...
