A Method for Skew-free Distribution of Digital Signals Using Matched Variable Delay Lines
(1992-03-01)
The ability to distribute signals everywhere in a circuit with controlled and known delays is essential in large, high-speed digital systems. We present a technique by which a signal driver can adjust the arrival time ...
Extracting and Representing Qualitative Behaviors of Complex Systems in Phase Spaces
(1991-03-01)
We develop a qualitative method for understanding and representing phase space structures of complex systems and demonstrate the method with a program, MAPS --- Modeler and Analyzer for Phase Spaces, using deep domain ...
Control Algorithms for Chaotic Systems
(1991-03-01)
This paper presents techniques that actively exploit chaotic behavior to accomplish otherwise-impossible control tasks. The state space is mapped by numerical integration at different system parameter values and ...
Contour Matching Using Local Affine Transformations
(1992-04-01)
Partial constraints are often available in visual processing tasks requiring the matching of contours in two images. We propose a non- iterative scheme to determine contour matches using locally affine transformations. ...
Programmable Applications: Interpreter Meets Interface
(1991-10-01)
Current fashion in "user-friendly'' software design tends to place an overreliance on direct manipulation interfaces. To be truly expressive (and thus truly user-friendly), applications need both learnable interfaces ...
Apparent Opacity Affects Perception of Structure from Motion
(1991-01-01)
The judgment of surface attributes such as transparency or opacity is often considered to be a higher-level visual process that would make use of low-level stereo or motion information to tease apart the transparent ...
Experience with Acore: Implementing GHC with Actors
(1990-08-01)
This paper presents a concurrent interpreter for a general-purpose concurrent logic programming language, Guarded Horn Clauses (GHC). Unlike typical implementations of GHC in logic programming languages, the interpreter ...
Indexing for Visual Recognition from a Large Model Base
(1990-08-01)
This paper describes a new approach to the model base indexing stage of visual object recognition. Fast model base indexing of 3D objects is achieved by accessing a database of encoded 2D views of the objects using a ...
Routing Statistics for Unqueued Banyan Networks
(1990-09-01)
Banyan networks comprise a large class of networks that have been used for interconnection in large-scale multiprocessors and telephone switching systems. Regular variants of Banyan networks, such as delta and butterfly ...
Revised Report On The Algorithmic Language Scheme
(1991-11-01)
Data and procedures and the values they amass, Higher-order functions to combine and mix and match, Objects with their local state, the message they pass, A property, a package, the control of point for a catch- In the ...
