Embedded Real-Time Linux for Cable Robot Control

October 2, 2002
Author(s)
Frederick M. Proctor, William P. Shackleford
Linux is a version of the Unix operating system distributed according to the open source model. Programmers are free to adapt the source code for their purposes, but are required to make their modifications or enhancements available as open source software

A Core Product Model for Representing Design Information

October 1, 2002
Author(s)
Steven J. Fenves
The report presents a core model for representing design information, motivated by the perceived needs of next-generation product development systems and drawing content-level requirements from a related study of design information flows. The core model

A Glyph Toolbox for Immersive Scientific Visualization

October 1, 2002
Author(s)
H W. Bullen, J S. Chang, A V. Harn, Steven G. Satterfield, Peter M. Ketcham, J E. Devaney
We describe a set of software, the Glyph ToolBox (GTB), for creating three dimensional (3D) glyphs. This software defines a single, general format for describing glyphs; it includes color and opacity parameters as well as location information.GTB is

A Representation of Acoustic Waves in Unbounded Domains

October 1, 2002
Author(s)
Bradley K. Alpert, Yu-Hsuan Chen
Compact, time-harmonic, acoustic sources produce waves that decay too slowly to be square-integrable on a line away from the sources. We introduce an inner product, arising directly from Green's second theorem, to form a Hilbert space of these waves, and

A Spline Algorithm for Modeling Cutting Errors on Turning Centers

October 1, 2002
Author(s)
David E. Gilsinn, Herbert T. Bandy, Alice V. Ling
Turned parts on turning centers are made up of features with profiles defined by arcs and lines. An error model for turned parts must take into account not only individual feature errors but also how errors carry over from one feature to another. In the

A Thermodynamic Study of the Reactions: 2-Dehydro-3Deoxy-D-Arabino-Heptanoate 7-Phosphate(aq) = {3-Dehydroquinate (ag) + Phosphate (aq)} and {3-Dehydroquinate(aq) =3-Dehydroshikimate(aq) + H 2 O(l)}

October 1, 2002
Author(s)
Yadu D. Tewari, Robert N. Goldberg, A R. Hawkins, H K. Lamb
Microcalorimetry and high-performance liquid chromatography (h.p.l.c.) have been used to conduct a thermodynamic investigation of reactions catalyzed by 3-dehydroquinate synthase and by 3-dehydroquinate dehydratase. These are the second and third reactions

Advanced Question Answering for Intelligence AQUAINT Website

October 1, 2002
Author(s)
Ellen M. Voorhees
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

An Analytical Approach to Shared Backup Path Provisioning in GMPLS Networks

October 1, 2002
Author(s)
Sanghun Lee, David W. Griffith, N-O Song
As GMPLS and its supporting set of protocols develop into a viable control plane for optical networks, an important function that they will need to support will be the restoration and protection function that has been a major feature of legacy optical

An Architecture for a Generic Data-Driven Machine Shop Simulator

October 1, 2002
Author(s)
Charles R. McLean, Albert T. Jones, Yung-Tsun Lee, Frank H. Riddick
In most cases, the effort required to develop a meaningful simulation for a small machine shop exceeds the resources available. Small shops typically do not have staff with appropriate technical qualifications required to develop custom simulations of

An IDEF1X Information Model for a Supply Chain Simulation

October 1, 2002
Author(s)
Yung-Tsun Lee, Shigeki Umeda
This paper describes the scope and configuration of the simulation model that is under development for a manufacturing supply chain. An information model that serves as a neutral interface specification is also presented in the paper. The supply chain

Application of Self-Assembled Technology to Probe Fiber Matrix-Adhesion

October 1, 2002
Author(s)
E Feresenbet, D T. Raghavan, Gale A. Holmes
Adhesion at the fiber-matrix interface of composite is often related to a combination of factors such as mechanical interlocking, physico-chemical interactions, and chemical bonding of the fiber-matrix interphase region. We demonstrate the use of (self

Applications Panel: Agents Applied to Autonomous Vehicles

October 1, 2002
Author(s)
Craig I. Schlenoff
In order to make an unmanned vehicle drive truly autonomously, many different software components are needed. Each of these components is tasked with providing a particular function that is necessary to accomplish the ultimate goal of autonomous driving

Atomic Force Microscopy of Semiconductor Line Edge Roughness

October 1, 2002
Author(s)
N G. Orji, Jayaraman Raja, Theodore V. Vorburger
Over the last two decades the width of patterned lines on semiconductor devices has continuously decreased. Based on technology trends predicted by the International Technology Roadmap for Semiconductors (ITRS), the linewidth of isolated gate lines on

BACnet Today- Significant new features and future enhancements

October 1, 2002
Author(s)
Steven T. Bushby, H M. Newman
The BACnet communication protocol standard is maintained by a standing committee of the American Society of Heating, Refrigerating, and air-conditioning Engineers under continuous maintenance procedures. Since its original publication in 1995 there have
