Parallel Computation of Vernier Offsets, Curvature and Chevrons in Humans
(1989-12-01)A vernier offset is detected at once among straight lines, and reaction times are almost independent of the number of simultaneously presented stimuli (distractors), indicating parallel processing of vernier offsets. ... -
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 Flow Graph Matching for Automated Program Recognition
(MIT Artificial Intelligence Laboratory, 1988-07)A flow graph matching algorithm has been implemented on the Connection Machine which employs parallel techniques to allow efficient subgraph matching. By constructing many different matchings in parallel, the algorithm is ... -
Parallel Function Application on a DNA Substrate
(1996-12-01)In this paper I present a new model that employs a biological (specifically DNA -based) substrate for performing computation. Specifically, I describe strategies for performing parallel function application in the ... -
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 ... -
Parallel Networks for Machine Vision
(1988-12-01)The amount of computation required to solve many early vision problems is prodigious, and so it has long been thought that systems that operate in a reasonable amount of time will only become feasible when parallel ... -
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 ... -
Parallel Simulation of Digital LSI Circuits
(1985-02)Integrated circuit technology has been advancing at a phenomenal rate over the last several years, and promises to continue to do so. If circuit design is to keep pace with fabrication technology, radically new approaches ... -
Parallel Simulation of Subsonic Fluid Dynamics on a Cluster of Workstations
(1995-12-01)An effective approach of simulating fluid dynamics on a cluster of non- dedicated workstations is presented. The approach uses local interaction algorithms, small communication capacity, and automatic migration of parallel ... -
Parallel Solutions to Geometric Problems on the Scan Model of Computation
(1988-02-01)This paper describes several parallel algorithms that solve geometric problems. The algorithms are based on a vector model of computation---the scan-model. The purpose of this paper is both to show how the model can ... -
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, ... -
Parallelizing Sequential Programs With Statistical Accuracy Tests
(2010-08-05)We present QuickStep, a novel system for parallelizing sequential programs. QuickStep deploys a set of parallelization transformations that together induce a search space of candidate parallel programs. Given a sequential ... -
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 ... -
Parameterized Types and Java
(1996-05)Java offers the real possibility that most programs can be written in a type-safe language However, for Java to be broadly useful, it needs additional expressive power. This paper extends Java in one area where more power ... -
ParaTran: A Transparent, Transaction Based Runtime Mechanism for Parallel Execution of Scheme
(1989-07)The number of applications requiring high speed symbolic computation and the performance requirements of these projects are both rapidly increasing. However, the computer science community's ability to produce high ... -
Parsing and Generating English Using Commutative Transformations
(1982-05-01)This paper is about an implemented natural language interface that translates from English into semantic net relations and from semantic net relations back into English. The parser and companion generator were implemented ... -
Parsing and Linguistic Explanation
(1985-04-01)This article summarizes and extends recent results linking deterministic parsing to observed "locality principles" in syntax. It also argues that grammatical theories based on explicit phrase structure rules are unlikely ... -
Parsing Intensity Profiles
(1975-05-01)Much low-level vision work in AI deals with one-dimensional intensity profiles. This paper describes PROPAR, a system that allows a convenient and uniform mechanism for recognizin such profiles. PROPAR is a modified ...
