A Multiprocessor Architecture Using Modular Arithmetic for Very High Precision Computation
(1989-04-01)
We outline a multiprocessor architecture that uses modular arithmetic to implement numerical computation with 900 bits of intermediate precision. A proposed prototype, to be implemented with off-the-shelf parts, will ...
Lexical Conceptual Structure and Generation in Machine Translation
(1989-06-01)
This report introduces an implemented scheme for generating target- language sentences using a compositional representation of meaning called lexical conceptual structure. Lexical conceptual structure facilitates two crucial ...
Conceptual Basis of the Lexicon in Machine Translation
(1989-08-01)
This report describes the organization and content of lexical information required for the task of machine translation. In particular, the lexical-conceptual basis for UNITRAN, an implemented machine translation system, ...
Causal/Temporal Connectives: Syntax and Lexicon
(1989-09-01)
This report elucidates the linguistic representation of temporal relations among events. This involves examining sentences that contain two clauses connected by words like once, by the time, when, and before. Specifically, ...
An Object-Oriented Software Reuse Tool
(1989-04-01)
The Object-oriented Reuse Tool (ORT) supports the reuse of object-oriented software by maintaining a library of reusable classes and recording information about their reusability as well as information associated with their ...
Networks and the Best Approximation Property
(1989-10-01)
Networks can be considered as approximation schemes. Multilayer networks of the backpropagation type can approximate arbitrarily well continuous functions (Cybenko, 1989; Funahashi, 1989; Stinchcombe and White, 1989). We ...
SQUIRT: The Prototypical Mobile Robot for Autonomous Graduate Students
(1989-07-01)
This paper describes an exercise in building a complete robot aimed at being as small as possible but using off-the-shelf components exclusively. The result is an autonomous mobile robot slightly larger than one cubic ...
Twilight Zones and Cornerstones: A Gnat Robot Double Feature
(1989-07-01)
We want to build tiny gnat-sized robots, a millimeter or two in diameter. They will be cheap, disposable, totally self-contained autonomous agents able to do useful things in the world. This paper consists of two parts. ...
The Standard Map Machine
(1989-09-01)
We have designed the Standard Map Machine(SMM) as an answer to the intensive computational requirements involved in the study of chaotic behavior in nonlinear systems. The high-speed and high-precision performance of ...
Residual Vibration Reduction in Computer Controlled Machines
(1989-02-01)
Control of machines that exhibit flexibility becomes important when designers attempt to push the state of the art with faster, lighter machines. Three steps are necessary for the control of a flexible planet. First, ...
