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 ...

The Weighted Histogram Analysis Method (WHAM) is a technique used to calculate free energy from molecular simulation data. WHAM recombines biased distributions of samples from multiple Umbrella Sampling simulations to yield ...

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 ...

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 ...

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 ...

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 ...

Most numerical software involves performing an extremely large volume of algebraic computations. This is both costly and time consuming in respect of computer resources and, for large problems, often super-computer power ...

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 ...

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, ...

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 ...

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 ...

A parameterization is proposed for the effects of symmetric instability (SI) on a resolved front. The parameterization is dependent on external forcing by surface buoyancy loss and/or down-front winds, which reduce potential ...

In recent times, the concepts of microsatellite development have been a versatile subject ranging from their ability to reduce overall cost of satellites to their improved efficiency and adaptability. This has brought new ...

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 ...

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 ...

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 ...

Key word grammars are defined to be the same as context free grammars, except that a production may specify a string of arbitrary symbols. These grammars define languages similar to those used in the programs CARPS and ...

A theory of the planning and debugging of programs is formalized as is context free grammar. The grammar is used to reveal the constituent structure of problem solving episodes, by parsing protocols in which programs ...

We describe the key role played by partial evaluation in the Supercomputer Toolkit, a parallel computing system for scientific applications that effectively exploits the vast amount of parallelism exposed by partial ...

I have implemented a simple "mechanical design compiler", that is a program which can convert high-level descriptions of a mechanical design into detail descriptions. (Human interaction is sometimes required.) The program ...
