On Interpreting Stereo Disparity
(1989-02-01)The problems under consideration center around the interpretation of binocular stereo disparity. In particular, the goal is to establish a set of mappings from stereo disparity to corresponding three-dimensional scene ... -
On Motion Planning with Uncertainty
(1984-08-01)Robots must successfully plan and execute tasks in the presence of uncertainty. Uncertainty arises from errors in modeling, sensing, and control. Planning in the presence of uncertainty constitutes one facet of the ... -
On Probabilistic Strategies for Robot Tasks
(1989-08-01)Robots must act purposefully and successfully in an uncertain world. Sensory information is inaccurate or noisy, actions may have a range of effects, and the robot's environment is only partially and imprecisely ... -
Online Learning of Non-stationary Sequences
(2003-06-12)We consider an online learning scenario in which the learner can make predictions on the basis of a fixed set of experts. The performance of each expert may change over time in a manner unknown to the learner. We formulate ... -
ONTIC: A Knowledge Representation System for Mathematics
(1987-07-01)Ontic is an interactive system for developing and verifying mathematics. Ontic's verification mechanism is capable of automatically finding and applying information from a library containing hundreds of mathematical ... -
Optimal Unsupervised Learning in Feedforward Neural Networks
(1989-01-01)We investigate the properties of feedforward neural networks trained with Hebbian learning algorithms. A new unsupervised algorithm is proposed which produces statistically uncorrelated outputs. The algorithm causes ... -
Parallel Coupled Micro-Macro Actuators
(1996-01-01)This thesis presents a new actuator system consisting of a micro-actuator and a macro-actuator coupled in parallel via a compliant transmission. The system is called the Parallel Coupled Micro-Macro Actuator, or PaCMMA. ... -
A Parallel Crossbar Routing Chip for a Shared Memory Multiprocessor
(1991-03-01)This thesis describes the design and implementation of an integrated circuit and associated packaging to be used as the building block for the data routing network of a large scale shared memory multiprocessor system. ... -
Parallel Methods for Synthesizing Whole-Hand Grasps from Generalized Prototypes
(1994-01-01)This report addresses the problem of acquiring objects using articulated robotic hands. Standard grasps are used to make the problem tractable, and a technique is developed for generalizing these standard grasps to ... -
A Parallel Processing Model of Musical Structures
(1971-09-01)Euterpe is a real-time computer system for the modeling of musical structures. It provides a formalism wherein familiar concepts of musical analysis may be readily expressed. This is verified by its application to the ... -
Parallelism in Manipulator Dynamics
(1984-12-01)This paper addresses the problem of efficiently computing the motor torques required to drive a lower-pair kinematic chain (e.g., a typical manipulator arm in free motion, or a mechanical leg in the swing phase) given ... -
A Parallelizing Compiler Based on Partial Evaluation
(1993-07-01)We constructed a parallelizing compiler that utilizes partial evaluation to achieve efficient parallel object code from very high-level data independent source programs. On several important scientific applications, ... -
Parameter Estimation in Chaotic Systems
(1995-04-01)This report examines how to estimate the parameters of a chaotic system given noisy observations of the state behavior of the system. Investigating parameter estimation for chaotic systems is interesting because of ... -
Passive and Active Grasping with a Prehensile Robot End-Effector
(1990-05-01)This report presents a design of a new type of robot end-effector with inherent mechanical grasping capabilities. Concentrating on designing an end-effector to grasp a simple class of objects, cylindrical, allowed a ... -
Passive Dynamics in the Control of Gymnastic Maneuvers
(1995-03-01)The control of aerial gymnastic maneuvers is challenging because these maneuvers frequently involve complex rotational motion and because the performer has limited control of the maneuver during flight. A performer can ... -
Performance Evaluation of the Scheme 86 and HP Precision Architecture
(1989-04-01)The Scheme86 and the HP Precision Architectures represent different trends in computer processor design. The former uses wide micro-instructions, parallel hardware, and a low latency memory interface. The latter ... -
The PHD: A Planar, Harmonic Drive Robot for Joint Torque Control
(1990-05-01)This thesis details the development of a model of a seven degree of freedom manipulator for position control. Then, it goes on to discuss the design and construction of a the PHD, a robot built to serve two purposes: ... -
Pi: A Parallel Architecture Interface for Multi-Model Execution
(1990-05-01)This thesis defines Pi, a parallel architecture interface that separates model and machine issues, allowing them to be addressed independently. This provides greater flexibility for both the model and machine builder. ... -
Piezoelectric Ultrasonic Micromotors
(1995-06-01)This report describes development of micro-fabricated piezoelectric ultrasonic motors and bulk-ceramic piezoelectric ultrasonic motors. Ultrasonic motors offer the advantage of low speed, high torque operation without ... -
PILOT: A Step Toward Man-Computer Symbiosis
(1966-09-01)PILOT is a programming system constructed in LISP. It is designed to facilitate the development of programs by easing the familiar sequence: write some code, run the program, make some changes, write some more code, ...
