High-Throughput Method for Determining Modulus of Polymer Blends

December 1, 2004
Author(s)
Carl G. Simon Jr., Naomi Eidelman, Y N. Deng, N Washburn
Polymer blending is commonly used to create materials with improved mechanical properties, but the resulting material properties can have a complex dependence on composition and processing conditions (Paul, 1986). In order to accelerate polymer-blend

Information Models for Product Representation: Core and Assembly Models

December 1, 2004
Author(s)
Sudarsan Rachuri, Mehmet M. Baysal, Utpal Roy, Sebti Foufou, Steven J. Fenves, Eswaran Subrahmanian, Kevin W. Lyons, Ram D. Sriram, Conrad Bock
This report presents a revised and unified view of the NIST Core Product Model (CPM) [1; 2] and the NIST Open Assembly Model (OAM) [3]. The CPM provides a base-level product model that is not tied to any vendor software; open; non-proprietary; simple

Interface Intermixing and In-Plane Grain Size in Aluminum-Transition Metal Bilayers

December 1, 2004
Author(s)
J D. Buchanan, T P. Hase, B K. Tanner, Cedric J. Powell, William F. Egelhoff Jr.
The correlation between grain size and intermixing in sputter deposited bilayers of the form X/Al and Al/X has been investigated by in-plane grazing incidence x-ray diffraction. We find a strong correlation between grain size and intermixing at the

Internet-Based Surface Metrology Algorithm Testing System

December 1, 2004
Author(s)
Son H. Bui, Thomas B. Renegar, Theodore V. Vorburger, Jayaraman Raja, Mark C. Malburg
This paper presents the development of an Internet-based surface metrology algorithm testing system. The system includes peer-reviewed surface analysis tools and a surface texture specimen database for parameter evaluation and algorithm verification. The

Limits to the Effectiveness of Metal-Containing Fire Suppressants

December 1, 2004
Author(s)
Gregory T. Linteris
This report reviews the literature on metal inhibition of flames and identifies metal species with potential as fire suppressant additives. To provide a basis for discussion, the detailed mechanism of inhibition of iron is reviewed, and the reasons for its

Link Scoped IPv6 Multicast

December 1, 2004
Author(s)
M K. Shin
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Matrix Decompositions and Quantum Circuit Design

December 1, 2004
Author(s)
Stephen Bullock
The n-qubit concurrence canonical decomposition (CCD) is a generalization of the two-qubit canonical decomposition SU(4)=[SU(2) (x) SU(2)] ? [SU(2) (x) SU(2)], where ? is the commutative group which phases the maximally entangled Bell basis. A prequel

MEMS Sensors for HVAC&R: Small, Fast, Cheap.

December 1, 2004
Author(s)
David A. Yashar, Piotr A. Domanski
Microelectronic mechanical systems (MEMS) have revolutionized the market for sensors by providing small, fast-responding measurement devices at lowcost. They have been widely accepted in several commonproducts. As an example, today’s automobile uses
