Offices are Open Systems
(1987-02-01)
This paper takes a prescriptive stance on how to establish the information-processing foundations for taking action and making decisions in office work from an open system perspective. We propose due process as a ...
Time-Frequency Representations for Speech Signals
(1987-05-01)
This work addresses two related questions. The first question is what joint time-frequency energy representations are most appropriate for auditory signals, in particular, for speech signals in sonorant regions. The ...
Summarizing Qualitative Behavior from Measurements of NonlinearsCircuits
(1989-05-01)
This report describes a program which automatically characterizes the behavior of any driven, nonlinear, electrical circuit. To do this, the program autonomously selects interesting input parameters, drives the circuit, ...
A Modern Differential Geometric Approach to Shape from Shading
(1989-06-01)
How the visual system extracts shape information from a single grey-level image can be approached by examining how the information about shape is contained in the image. This technical report considers the characteristic ...
Robust 2-D Model-Based Object Recognition
(1988-05-01)
Techniques, suitable for parallel implementation, for robust 2D model-based object recognition in the presence of sensor error are studied. Models and scene data are represented as local geometric features and robust ...
Generating Circuit Tests by Exploiting Designed Behavior
(1988-12-01)
This thesis describes two programs for generating tests for digital circuits that exploit several kinds of expert knowledge not used by previous approaches. First, many test generation problems can be solved efficiently ...
Visual Navigation: Constructing and Utilizing Simple Maps of an Indoor Environment
(1989-03-01)
The goal of this work is to navigate through an office environmentsusing only visual information gathered from four cameras placed onboard a mobile robot. The method is insensitive to physical changes within the room ...
Using Special-Purpose Computing to Examine Chaotic Behavior in Nonlinear Mappings
(1989-09-01)
Studying chaotic behavior in nonlinear systems requires numerous computations in order to simulate the behavior of such systems. The Standard Map Machine was designed and implemented as a special computer for performing ...
Toward a Theory of Representation Design
(1989-05-01)
This research is concerned with designing representations for analytical reasoning problems (of the sort found on the GRE and LSAT). These problems test the ability to draw logical conclusions. A computer program was ...
Probabilistic Solution of Inverse Problems
(1985-09-01)
In this thesis we study the general problem of reconstructing a function, defined on a finite lattice from a set of incomplete, noisy and/or ambiguous observations. The goal of this work is to demonstrate the generality ...
