Standardization of File Recovery Classification and Authentication

December 1, 2019
Author(s)
Eoghan Casey, Alexander J. Nelson, Jessica Hyde
Digital forensics can no longer tolerate software that cannot be relied upon to perform specific functions such as file recovery. The root of this problem is a lack of clearly defined software requirements, which compels users and tool testers to make

Thermal response of a composite floor system to the standard fire exposure

December 1, 2019
Author(s)
Dilip K. Banerjee
This paper discusses the development of a finite element model (FEA) of a full-scale composite floor system and application of this model to predict the heating of steel members when exposed to a standard fire during fire resistance experiments. The model

TOPOLOGY OF VOIDS AND CHANNELS IN SELECTED PORPHYRINIC COMPOUNDS

December 1, 2019
Author(s)
Lawrence P. Cook, Greg Brewer, Daniel Siderius, Winnie Wong-Ng
Porphyrinic compounds are of increasing interest to the materials science community, yet little attention has been paid to crystallographically controlled voids and channels in these materials. We have conducted an initial survey of the voids and channels

Efficient upgrading of CO to C3 fuel using asymmetric C-C coupling active sites

November 29, 2019
Author(s)
Lee J. Richter, Ahmad R. Kirmani, Xue Wang, Wang Ziyuan, Dinh Cao-Thang, Li Jun, Nam Dae-Hyun, Li Fengwang, Huang Chun-Wei, Tan Chih-Shan, Chen Zitao, Chi Miaofang, Gabardo M. Christine, Seiifitokaldani Ali, Todorovic Petar, Proppe Andrew, Pang Yuanjie, wang yuhang, Ip H. Alexander, Shen-Chuan Lo, shana O. kelley, David Sinton, Edward H. Sargent, Tao-Tao Zhuang, Benjamin Scheffel
The electroreduction of C1 feedgas to high-energy-density fuels provides an attractive avenue to the storage of renewable electricity. Much progress has been made to improve selectivity to C1 and C2 products, however, the selectivity to desirable high

CHALLENGES IN REPRESENTING MANUFACTURING PROCESSES FOR SYSTEMATIC SUSTAINABILITY ASSESSMENTS - WORKSHOP ON JUNE 21, 2018

November 27, 2019
Author(s)
Arvind Shankar Raman, Dustin Harper, Karl Haapala, Barbara S. Linke, William Z. Bernstein, KC Morris
A workshop on Challenges in Representing Manufacturing Processes for Systematic Sustainability Assessments, jointly sponsored by the U.S. National Science Foundation, the U.S. National Institute of Standards and Technology, ASTM International, the American

Developing Cyber Resilient Systems: A Systems Security Engineering Approach

November 27, 2019
Author(s)
Ronald S. Ross, Victoria Y. Pillitteri, Richard Graubart, Deborah Bodeau, Rosalie McQuaid
This publication is used in conjunction with ISO/IEC/IEEE 15288:2015, Systems and software engineering--Systems life cycle processes, NIST Special Publication 800-160, Volume 1, Systems Security Engineering--Considerations for a Multidisciplinary Approach

Exploring the Limits of Bottom-Up Gold Filling to Fabricate Diffraction Gratings

November 27, 2019
Author(s)
Daniel Josell, Stephen J. Ambrozik, Maureen E. Williams, A E. Hollowell, Christian Arrington, Shinichiro Muramoto, Thomas P. Moffat
Gold deposition on rotating disk electrodes, Bi3+ adsorption on planar Au films and superconformal Au filling of trenches up to 45 m deep are examined in Bi+3-containing Na3Au(SO3)2 electrolytes with pH between 9.5 and 11.5. Higher pH is found to increase

Spectrum of Ni V in the Vacuum Ultraviolet

November 27, 2019
Author(s)
Jacob W. Ward, A J. Raassen, Alexander Kramida, Gillian Nave
This work presents 97 remeasured Fe V wavelengths (1200 Å to 1600 Å) and 123 remeasured Ni V wavelengths (1200 Å to 1400 Å) with uncertainties of approximately 2 mÅ. An additional 67 remeasured Fe V wavelengths and 72 remeasured Ni V wavelengths with

On Practice and Theory of Constructive Composite Geometry and Topology

November 25, 2019
Author(s)
Thomas D. Hedberg Jr., Allison Barnard Feeney, Vijay Srinivasan
This paper synthesizes a theory from industrial best practices codified in recent standards. Recent editions of ASME and ISO standards codify the evolving industrial best practices in defining and modeling the information about products made from fibrous

Voices of First Responders - Examining Public Safety Communication from the Rural Perspective

November 25, 2019
Author(s)
Kristen K. Greene, Shanee Dawkins, Mary Theofanos, Michelle P. Steves, Susanne M. Furman, Yee-Yin Choong, Sandra S. Prettyman
With the newly created Nationwide Public Safety Broadband Network (NPSBN), the public safety community has a unique opportunity to review and improve communication technology for first responders, in urban, suburban, and rural areas. Understanding the

A Nonlinear Multivariate Cryptosystem Based on a Random Linear Code

November 24, 2019
Author(s)
Daniel C. Smith-Tone, Cristina Tone
We introduce a new technique for building multivariate encryption schemes based on random linear codes. The construction is versatile, naturally admitting multiple modifications. Among these modifications is an interesting embedding modifier -- any

Augmenting Fiat Currency with an Integrated Managed Cryptocurrency

November 24, 2019
Author(s)
Peter M. Mell
In this work, we investigate how the governance features of a managed currency (e.g., a fiat currency) can be built into a cryptocurrency in order to leverage potential benefits found in the use of blockchain technology and smart contracts. The resulting

Implementing a Protocol Native Managed Cryptocurrency

November 24, 2019
Author(s)
Peter M. Mell, Aurelien M. Delaitre, Frederic J. de Vaulx, Philippe J. Dessauw
Previous work presented a theoretical model based on the implicit Bitcoin specification for how an entity might issue a cryptocurrency that mimics features of fiat currencies. Novel to this work were mechanisms by which the issuing entity could manage the

NIST Handbook 133: Checking the Net Contents of Packaged Goods (2020 Ed.)

November 24, 2019
Author(s)
Breyanna M. Blackwell, David Sefcik, Lisa Warfield
This handbook has been prepared as a procedural guide for the compliance testing of net content statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance of the- results of the packaging, distribution, and
