Dynamic Graphics Using Quasi Parallelism
(1978-06-01)
Dynamic computer graphics is best represented as several processes operating in parallel. Full parallel processing, however, entails much complex mechanism making it difficult to write simple, intuitive programs for ...
EMACS: The Extensible, Customizable, Self-Documenting Display Editor
(1981-03-01)
EMACS is a display editor which is implemented in an interpreted high level language. This allows users to extend the editor by replacing parts of it, to experiment with alternative command languages, and to share ...
Understanding Understanding Mathematics
(1978-08-01)
In this paper we look at some of the ingredients and processes involved in the understanding of mathematics. We analyze elements of mathematical knowledge, organize them in a coherent way and take note of certain ...
The TV Turtle: A Logo Graphics System for Raster Displays
(1976-06-01)
Until recently, most computer graphics systems have been oriented toward the display of line drawins, continually refreshing the screen from a display list of vectors. Developments such as plasma panel displays and ...
The Competence/Performance Dichotomy in Programming
(1977-01-01)
We consider the problem of automating some of the duties of programmers. We take as our point of departure the claim that data management has been automated to the point where the programmer concerned only about the ...
Overlays: A Theory of Modelling for Computer Aided Instruction
(1977-02-01)
Overlay modelling is a technique for describing a student's problem solving skills in terms of modular program designed to be an expert for the given domain. The model is an overlay on the expert program in that it consists ...
The FRL Primer
(1977-07-01)
The Frame Representation Language (FRL) is an experimental language written to explore the use of frames as a knowledge representation technique. The term 'frame' as used in FRL was inspired by Minsky's [75] development ...
NUDGE, A Knowledge-Based Scheduling Program
(1977-02-01)
Traditional scheduling algorithms (using the techniques of PERT charts, decision analysis or operations research) require well-defined quantitative, complete sets of constraints. They are insufficient for scheduling ...
Occlusion Clues and Subjective Contours
(1976-06-01)
The paper describes some experiments with a visual agnosia patient who has lost the abillity to perceive subjective contours. The patient's interpretations of simple examples of occlusion indicate that he fails to ...
Development of Musical Intelligence II: Children's Representation of Pitch Relations
(1976-12-01)
The work reported here is an outgrowth of studies in the development of musical intelligence and learning that have been underway for about four years. Beginning as one of the activities in the LOGO Lab (a part of the ...
