Report on the Development of the Advanced Encryption Standard (AES)

June 1, 2001
Author(s)
James R. Nechvatal, Elaine B. Barker, Lawrence E. Bassham, William E. Burr, Morris J. Dworkin, James Foti, E Roback
In 1997, the National Institute of Standards and Technology (NIST) initiated a process to select a symmetric-key encryption algorithm to be used to protect sensitive (unclassified) Federal information in furtherance of NIST's statutory responsibilities. In

Shear Viscosity of Phase Separating Polymer Blends With Viscous Asymmetry

June 1, 2001
Author(s)
H Jeon, Erik K. Hobbie
Rheo-optical measurements of phase separating polymer mixtures under simple shear flow have been used to investigate the influence of domain morphology on the viscosity of emulsion-like polymer blends. The morphology and viscosity of low-molecular weight

Should (T 1 - T 2 ) Have Larger Uncertainty Than T 1 ?

June 1, 2001
Author(s)
Lee Y. G
In interlaboratory comparisons, laboratories sometimes use a transfer instrument to realize the value of a laboratory standard to compare the relative biases of their measurement processes and standards. One summary of interest from such comparisons is the

Small Fixed-Point Cells for Use in Dry Well Block Calibrators

June 1, 2001
Author(s)
Gregory F. Strouse
As part of a research project for the Combined Calibration Group (CCG) of the U.S. Armed Forces, three rugged fixed-point cells were developed for use in dry well block calibrators (DWBCs). The small fixed-point cells of the water triple point (0.01 C)

Solid State Sintering

June 1, 2001
Author(s)
J Blendell
The basic processes which control the solid state sintering of crystalline materials are reviewed. The stages of sintering are described and model which predict the evolution of the microstructure are presented. The effects of dihedral angle and pore

Spin-on Nanoparticle Tin Oxide for Microhotplate Gas Sensors

June 1, 2001
Author(s)
Richard E. Cavicchi, R M. Walton, M I. Aquino-Class, J D. Allen, B. Panchapakesan
A colloidal suspension of tin oxide nanoparticles is used to prepare a highly sensitive gas sensing film on a microhotplate. Fabrication consists of spin-coating the solution over an array of micromachined hotplates and annealing. A thermolithographic

Standard Reference Material 2100: Fracture Toughness of Ceramics

June 1, 2001
Author(s)
George D. Quinn, K Xu, R J. Gettings, J A. Salem, J Swab
New Standard Reference Material (SRM) 2100 is the first reference material in the world for the property fracture toughness for any class material. The SRM is for ceramic fracture toughness and may be used with any ceramic fracture toughness test method

Structural Ceramics Database (Version June 2001)

June 1, 2001
Author(s)
R G. Munro
An update of the NIST Standard Reference Database Number 30, the Structural Ceramics Database, has been completed. This update, designated here as Version June 2001, increases the number of reference citations from 431 to 731, and increases the number of

Switching Dynamics and Critical Behavior of Standard Problem No. 4

June 1, 2001
Author(s)
Robert McMichael, Michael J. Donahue, Donald G. Porter, J Eicke
We report switching dynamics for uMAG standard problem no. 4, a 500 nm x 125 nm x 3 nm rectangle of material with properties to mimic Permalloy. Siwtching dynamics are calculated for fields applied instantaneously to an initial s-state: Field 1 at 170o and

Taming Active Content

June 1, 2001
Author(s)
Wayne Jansen
The private and public sectors depend heavily upon information technology (IT) systems to perform essential, mission-critical functions. As technology improves to provide new capabilities and features, new vulnerabilities are often introduced as well

The Application of High-Speed CNC Machining to Prototype Production

June 1, 2001
Author(s)
Tony L. Schmitz, Matthew A. Davies, Brian S. Dutterer, J C. Ziegert
To reduce delays in the design and manufacture of a new part, rapid prototyping is often employed to minimize lead times. In this paper, the application of high-speed machining to the production of monolithic, metallic, functional prototypes is discussed

The IMS MISSION Architecture for Distributed Manufacturing Simulation

June 1, 2001
Author(s)
Charles R. McLean, Frank H. Riddick
This paper presents an overview of a neutral reference architecture for integrating distributed manufacturing simulation systems with each other, with other manufacturing software applications, and with manufacturing data repositories. Other manufacturing

The NIST Industrial Thermometer Calibration Laboratory

June 1, 2001
Author(s)
C D. Vaughn, Gregory F. Strouse
The NIST Industrial Thermometer Calibration (ITC) Laboratory provides calibrations of industrial thermometers over the range from 196 C to 550 C. The different types of thermometers include liquid-in-glass (LiG), thermistors, thermocouples (

The Role of Simulation in Strategic Manufacturing

June 1, 2001
Author(s)
Swee K. Leong, Charles R. McLean
Simulation technology holds tremendous promise for reducing costs, improving quality, and shortening the time-to-market for manufactured goods. Unfortunately, this technology still remains largely underutilized by industry today. This paper suggests
