Security for Telecommuting and Broadband Communications

November 1, 2002
Author(s)
Shirley M. Radack
This bulletin summarizes NIST SP 800-46, Security for Telecommuting and Broadband Communications, published September 2002. The report discusses both technical and policy issues, and provides guidance on using personal firewalls, strengthening the security

Guidelines for the Development of Abstract Test Suites, Edition 2

August 1, 2001
Author(s)
Allison Barnard Feeney
ISO 10303 is an International Standard for the computer-interpretable representation of product data and for exchange of product data. The objective is to provide a neutral mechanism capable of describing product data throughout their life cycle. This

Extinction Coefficients for Dielectric and Conducting Doublets of Spheres

January 1, 1998
Author(s)
Egon Marx
The extinction cross-sections of doublets of polystyrene and carbon spheres are determined using the optical theorem. The forward scattering amplitude is computed using the single integral equation method. The extinction cross-sections of the doublets are

SEC-SAXS/MC Ensemble Structural Studies of the Microtubule Binding Protein Cdt1 Show Monomeric, Folded-Over Conformations

June 1, 2025
Author(s)
Kyle Smith, Srinivas Chakravarthy, Manas Chakraborty, Kristen M. Vosberg, Marco Tonelli, Maximilian G. Plach, Arabela A. Grigorescu, Joseph E. Curtis, Dileep Varma
Cdt1 is a mixed folded protein critical for DNA replication licensing and it also has a "moonlighting" role at the kinetochore via direct binding to microtubules and the Ndc80 complex. However, it is unknown how the structure and conformations of Cdt1

… as part of access management. With the emergence of computing devices, such as tablets, hybrid computers, and, in … while the other leverages hardware built into many computing devices used today. This project resulted in a …

Data-driven Discovery of 3D and 2D Thermoelectric Materials

June 26, 2018
Author(s)
Kamal Choudhary, Kevin Garrity, Francesca Tavazza
Abstract: In this work, we perform a systematic search for high-efficiency, three-dimensional (3D) and two-dimensional (2D) thermoelectric materials by combining semiclassical transport techniques with density functional theory (DFT) calculations. Out of

The Algebra of Systems and System Interactions with an application to Smart Grid

October 14, 2016
Author(s)
Charif Mahmoudi, Hasnae Bilil, Edward R. Griffor
Systems are integrations of devices or component elements and even other systems. The notion of a system comprehends engineered and biological or mechanical or physical systems. Examples include information and dynamical systems as well as integrations of

A Hybrid CPU-GPU System for Stitching Large Scale Optical Microscopy Images

September 12, 2014
Author(s)
Timothy Blattner, Walid Keyrouz, Joe Chalfoun, Bertrand C. Stivalet, Mary C. Brady, Shujia Zhou
Researchers in various fields are using optical microscopy to acquire very large images, 10K--200K of pixels per side. Optical microscopes acquire these images as grids of overlapping partial images (thousands of pixels per side) that are then stitched

Developing an Analysis of Threats to Voting Systems: Workshop Summary

October 7, 2005
Author(s)
Allan C. Eustis
The Help America Vote Act (HAVA) of 2002 has given NIST a key role in helping to realize nationwide improvements in voting systems by January 2006. NIST research activities authorized by HAVA include the security of computers, computer networks, and

Information Depth for Elastic-Peak Electron Spectroscopy

February 1, 2004
Author(s)
Aleksander Jablonski, Cedric J. Powell
We present a formalism for calculating the information depth (ID) for elastic-peak electron spectroscopy (EPES) in which a measurement is made of the intensity of elastically-backscattered electrons for an amorphous or polycrystalline material and a

User's Manual for Lidar Target Simulator

March 1, 2000
Author(s)
J A. Worthey, Kathleen M. Higgins
This is the operator's manual for a target simulator for speed-measuring lidars, and for the computer program VS, which is a key part of the simulator. This is the simulator referred to in DOT HS 808 539, Model minimum performance specifications for lidar

Benchmark Database for Input and Validation of Multiphase Combustion Models.

October 11, 1999
Author(s)
J F. Widmann, S R. Charagundla, Cary Presser
Control of process efficiency and the formation of species byproducts from industrial thermal oxidation systems (e.g., power generation and treatment of liquid chemical wastes), is generally based on a priori knowledge of the input stream physical and
