Constraints on the Visual Interpretation of Surface Contours
(1979-03-01)
This article examines the computational problems underlying the 3-D interpretation of surface contours. A surface contour is the image of a curve across a physical surface, such as the edge of a shadow cast across a ...
CADR
(1979-05-01)
The CADR machine, a revised version of the CONS machine, is a general-purpose, 32-bit microprogrammable processor which is the basis of the Lisp-machine system, a new computer system being developed by the Laboratory ...
Learning Disjunctive Concepts From Examples
(1979-09-01)
This work proposes a theory for machine learning of disjunctive concepts. The paradigm followed is one of teaching and testing, where the teaching is accomplished by presenting a sequence of positive and negative ...
Instrumental With and the Control Relation in English
(1979-11-01)
This paper explores the nature of the underlying representation of a sentence, that representation formulated to make explicit the semantic structure of a sentence as a description of an event. It argues that the ...

During the school year 1977/78 four computers equipped with LOGO and Turtle Graphics were installed in an elementary school in Brookline, Mass. All sixth grade students in the school had between 20 and 40 hours of ...
Toward a Remotely-Manned Energy and Production Economy
(1979-09-01)
We can solve many problems of Energy, Health, Productivity, and Environmental Quality by improving the technology of remote control. This will produce Nuclear Safety and Security, Advances in Mining, Increases in ...
Mechanical Arm Control
(1979-10-01)
This paper discusses three main problems associated with the control of the motion of a mechanical arm. 1) Transformation between different coordinate systems associated with the arm. 2) Calculation of detailed ...

(1979-09-01)
During the school year 1977/78 four computers equipped with LOGO and Turtle Graphics were installed in an elementary school in Brookline, Mass. All sixth grade students in the school had between 20 and 40 hours of ...
Procedural Attachment
(1979-08-01)
A frame-based reasoning system is extended to deal with procedural attachment. Arguments are given why procedural attachment is needed in a symbolic reasoner. The notion of an infinitary concept is introduced. Conventions ...
Reasoning Modeled as a Society of Communicating Experts
(1979-06-01)
This report describes a domain independent reasoning system. The system uses a frame-based knowledge representation language and various reasoning techniques including constraint propagation, progressive refinement, ...
