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

Carbonyl Sulfide: A Review of its Chemistry and Properties

October 1, 2002
Author(s)
P D. Svoronos, Thomas J. Bruno
A number of years have elapsed since the last comprehensive review of the chemical properties of carbonyl sulfide (COS), with specific attention to the tendency of this fluid to undergo hydrolysis. Since that time, some important issues have arisen

Certification of Standard Reference Material 1473b, Low Density Polyethylene Resin

October 1, 2002
Author(s)
J R. Maurey, Carl R. Schultesiz, William R. Blair, Kathleen M. Flynn
The melt flow rate of Standard Reference Material (SRM) 1473b, a polyethylene resin, was determined to be 1.13 g/10 min at 190 degrees C under a load of 2.16 kg using the ASTM Method D 1238-00. The average results from 48 determinations on samples with a

Chapter 13: Economic Analysis and Green Buildings

October 1, 2002
Author(s)
S Fuller
Building economics, value engineering, and cost engineering are the three main fields that explicitly include an economic evaluation in building-related project analyses. The common theme that ties the three disciplines together is that each is concerned

Confirmation of Interstellar Acetone

October 1, 2002
Author(s)
Lewis E. Snyder, Francis J. Lovas, David Mehringer, Nina Yanti Miao, Y J. Kuan, J M. Hollis
We present new observations of interstellar acetone [(CH3)(2) CO] from both the NRAO 12 m and the BIMA array. We report NRAO 12 m detections of 13 new acetone emission features that can be assigned to 20 acetone transitions. These assignments are based on

Cost Effective Use of Formal Methods in Verification and Validation Foundations

October 1, 2002
Author(s)
D. Richard Kuhn, Ramaswamy Chandramouli, R W. Butler
Formal methods offer the promise of significant improvements in verification and validation, and may be the only approach capable of demonstrating the absence of undesirable system behavior. But it is widely recognized that these methods are expensive, and
