Wusor II: A Computer Aided Instruction Program with Student Modelling Capabilities
(1977-05-01)
Wusor II is the second program that has been developed to tutor students in the game of Wumpus. From the earlier efforts with Wusor I it was possible to produce a rule-based expert which processed a relatively complete ...
The Minimum Energy Movement for a Spring Muscle Model
(1977-09-01)
There are many ways of programming an actuator or effector for movement between the same two points. In the interest of efficiency it is sometimes desirable to program that trajectory which requires the least amount ...
Fast Arithmetic in MACLISP
(1977-09-01)
MacLISP provides a compiler which produces numerical code competitive in speed with some FORTRAN implementations and yet compatible with the rest of the MacLISP system. All numerical programs can be run under MacLISP ...
Data Representations in PDP-10 MACLISP
(1977-09-01)
The internal representations of the various MacLISP data types are presented and discussed. Certain implementation tradeoffs are considered. The ultimate decisions on these tradeoffs are discussed in the light of ...
Configuration Space Control
(1977-12-01)
Complicated systems with non-linear time-varying behavior are difficult to control using classical linear feedback methods applied separately to individual degrees of freedom. At the present, mechanical manipulators, ...
Representation and Recognition of the Spatial Organization of Three Dimensional Shapes
(1977-05-01)
The human visual process can be studied by examining the computational problems associated with deriving useful information from retinal images. In this paper, we apply this approach to the problem of representing ...
Light Source Effects
(1977-05-01)
The perception of surface luster in achromatic single view images seems to depend on the existence of regions with source-like properties. These regions are due to the interaction of specular component of the surface's ...
Developing a Computational Representation for Problem Solving Skills
(1978-10-01)
This paper describes the evolution of a problem solving model over several generations of computer coaches. Computer coaching is a type of computer assisted instruction in which the coaching program observes the ...
Causal Reasoning and Rationalization in Electronics
(1978-09-01)
This research attempts to formalize the type of causal arguments engineerings employ to understand circuit behavior. A causal argument consists of a sequence of changes to circuit quantities (called events), each of ...
A Proposal for a Computational Model of Anatomical and Physiological Reasoning
(1978-11-01)
The studies of anatomy and physiology are fundamental ingredients of medical education. This paper identifies six ways in which such functional knowledge serves as the underpinnings for general medical reasoning, and ...
