Theory of Handwriting
(1980-03-01)Handwriting production is viewed as a constrained modulation of an underlying oscillatory process. Coupled oscillations in horizontal and vertical directions produce letter forms, and when superimposed on a rightward ... -
A Theory of Quantitative Inference Applied to a Mechanical Design Compiler
(1989-01-01)This thesis presents the ideas underlying a computer program that takes as input a schematic of a mechanical or hydraulic power transmission system, plus specifications and a utility function, and returns catalog numbers ... -
Thread Scheduling Mechanisms for Multiple-Context Parallel Processors
(1995-06-01)Scheduling tasks to efficiently use the available processor resources is crucial to minimizing the runtime of applications on shared-memory parallel processors. One factor that contributes to poor processor utilization ... -
Three-Dimensional Correspondence
(1998-12-01)This paper describes the problem of three-dimensional object correspondence and presents an algorithm for matching two three-dimensional colored surfaces using polygon reduction and the minimization of an energy function. ... -
Three-Dimensional Motion Estimation Using Shading Information in Multiple Frames
(1989-09-01)A new formulation for recovering the structure and motion parameters of a moving patch using both motion and shading information is presented. It is based on a new differential constraint equation (FICE) that links the ... -
Three-Dimensional Recognition of Solid Objects from a Two-Dimensional Image
(1988-10-01)This thesis addresses the problem of recognizing solid objects in the three-dimensional world, using two-dimensional shape information extracted from a single image. Objects can be partly occluded and can occur in ... -
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 ... -
Toward A Model Of Children's Story Comprehension
(1972-12-01)How does a person answer questions about children's stories? For example, consider 'Janet wanted Jack's paints. She looked at the picture he was painting and said 'Those paints make your picture look funny.' The ... -
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 ... -
Towards a Computational Theory of Definite Anaphora Comprehension in English Discourse
(1979-06-01)This report investigates the process of focussing as a description and explanation of the comprehension of certain anaphoric expressions in English discourse. The investigation centers on the interpretation of definite ... -
Towards Intelligent Structures: Active Control of Buckling
(1994-05-01)The buckling of compressively-loaded members is one of the most important factors limiting the overall strength and stability of a structure. I have developed novel techniques for using active control to wiggle a ... -
Towards Man-Machine Interfaces: Combining Top-down Constraints with Bottom-up Learning in Facial Analysis
(2002-09-01)This thesis proposes a methodology for the design of man-machine interfaces by combining top-down and bottom-up processes in vision. From a computational perspective, we propose that the scientific-cognitive question ... -
A Trainable System for Object Detection in Images and Video Sequences
(2000-05-01)This thesis presents a general, trainable system for object detection in static images and video sequences. The core system finds a certain class of objects in static images of completely unconstrained, cluttered scenes ... -
Trajectory and Force Control of a Direct Drive Arm
(1986-09-01)Using the MIT Serial Link Direct Drive Arm as the main experimental device, various issues in trajectory and force control of manipulators were studied in this thesis. Since accurate modeling is important for any ... -
Translucent Procedures, Abstraction without Opacity
(1993-10-01)This report introduces TRANSLUCENT PROCEDURES as a new mechanism for implementing behavioral abstractions. Like an ordinary procedure, a translucent procedure can be invoked, and thus provides an obvious way to capture ... -
Truth Maintenance Systems for Problem Solving
(1978-01-01)The thesis developed here is that reasoning programs which take care to record the logical justifications for program beliefs can apply several powerful, but simple, domain-independent algorithms to (1) maintain the ... -
TYPICAL: A Knowledge Representation System for Automated Discovery and Inference
(1987-08-01)TYPICAL is a package for describing and making automatic inferences about a broad class of SCHEME predicate functions. These functions, called types following popular usage, delineate classes of primitive SCHEME ... -
Understanding and Modeling the Behavior of a Harmonic Drive Gear Transmission
(1992-05-01)In my research, I have performed an extensive experimental investigation of harmonic-drive properties such as stiffness, friction, and kinematic error. From my experimental results, I have found that these properties ... -
Understanding Simple Picture Programs
(1974-04-01)What are the characteristics of the process by which an intent is transformed into a plan and then a program? How is a program debugged? This paper analyzes these questions in the context of understanding simple turtle ... -
Understanding Subsystems in Biology through Dimensionality Reduction, Graph Partitioning and Analytical Modeling
(2003-02-05)Biological systems exhibit rich and complex behavior through the orchestrated interplay of a large array of components. It is hypothesized that separable subsystems with some degree of functional autonomy exist; deciphering ...
