Creating Training Data for Scientific Named Entity Recognition with Minimal Human Effort

June 8, 2019
Author(s)
Roselyne B. Tchoua, Aswathy Ajith, Zhi Hong, Logan T. Ward, Kyle Chard, Debra Audus, Shrayesh N. Patel, Juan J. de Pablo, Ian Foster
Scientific Named Entity Referent Extraction is often more complicated than traditional Named Entity Recognition (NER). For example, in polymer science, chemical structure may be encoded in a variety of nonstandard naming conventions, and authors may refer

Fire Dynamics Simulator (Version 3): User's Guide (NISTIR 6784)

November 1, 2001
Author(s)
Kevin B. McGrattan, Glenn P. Forney, J E. Floyd, Simo A. Hostikka
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

The Automated Manufacturing Research Facility of the National Bureau of Standards

August 1, 1983
Author(s)
Cita M. Furlani, Ernest Kent, Howard Bloom, Charles R. McLean
A major facility for manufacturing research is being established at the National Bureau of Standards (NBS). NBS is addressing the measurement and standards needs for the automation of the small batch, discrete parts manufacturing industries. The Automated

Detection of l-C3H+ in Sgr B2(N) and Sgr B2(OH) and Refinement of its Spectroscopic Constants via the Publicly Available PRIMOS Survey and the Barry E. Turner Legacy Survey

September 1, 2013
Author(s)
Francis J. Lovas, Brett A. McGuire, P. B. Carroll, Ryan A. Loomis, Geoffery A. Blake, Jan M. Hollis, Phillip R. Jewell, Anthony J. Remijan
Pety et al. (2012) recently reported the detection and assignment of l-C3H+ in the Horsehead nebula. Here, we expand that analysis to include the J = 1 - 0 and J = 2 - 1 transitions of l-C3H+ observed in absorption towards Sgr B2(N) in data from the

A Rigorous Attempt to Verify Interstellar Glycine

February 1, 2005
Author(s)
Lewis E. Snyder, Francis J. Lovas, J M. Hollis, Douglas N. Friedel, P R. Jewell, A Remijan, Vadim V. Ilyushin, E A. Alekseev, S K. Dyubko
In 2003, Kuan, Charnley, and co-workers claimed the detection of interstellar glycine (NH2 CH2COOH) based on the detection of 27 lines in 19 different spectral bands in one or more of the sources Sgr B2(N-LMH), Orion KL, and W51 e1/e2. They supported their

STEP Production Cell Technical Development Plan

October 1, 1990
Author(s)
James E. Fowler
This document describes a plan to construct a prototype STEP-based manufacturing cell to demonstrate how parts are produced in a STEP environment. The manufacturing cell is an integral part of an overall project to establish the National PDES Testbed at

Lessons learned in the design of reference fiducials for layer-wise analysis of test coupons made by laser powder bed fusion

April 16, 2021
Author(s)
Massimiliano Ferrucci, Tom Craeghs, Sven Cornelissen, Michele Pavan, Wim Dewulf, Alkan Donmez
The ability to align ex-situ inspection data of an additively manufactured (AM) part to its build geometry can be helpful, for example, to correlate observed in-situ monitoring events or features to measured discontinuities, such as pores and cracks, in ex

Practical Combinatorial Testing

October 7, 2010
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
Combinatorial testing can help detect problems like this early in the testing life cycle. The key insight underlying t-way combinatorial testing is that not every parameter contributes to every fault and most faults are caused by interactions between a

Guide to Auditing for Controls and Security: A System Development Life Cycle Approach

April 1, 1988
Author(s)
Zella G. Ruthberg, Bonnie T. Fisher, William E. Perry, John W. Lainhart, James G. Cox, Mark Gillen, Douglas B. Hunt
This guide addresses auditing the system development life cycle (SDLC) process for an automated information system (AIS), to ensure that controls and security are designed and built into the system. The guide also presents a process for deciding which

A Perspective on Nonvolatile Magnetic Memory Technology

December 21, 2016
Author(s)
Ronald B. Goldfarb
Magnetic random-access memory (MRAM) is characterized by nonvolatility, low energy dissipation, high endurance (repeated writing), scalability to smaller dimensions, compatibility with complementary metal-oxide semiconductor (CMOS) processing, resistance

Emulation as a Design Tool in the Development of Real-Time Control Systems

September 1, 1984
Author(s)
Howard Bloom, Cita M. Furlani, Tony Barbera
A major facility for manufacturing research is being established at the National Bureau of Standards. The Automated Manufacturing Research Facility (AMRF) will provide a testbed where measurement research of computer integrated manufacturing systems can be

Acquiring, Analyzing, and Using Complete Three-Dimensional Aggregate Shape Information

April 1, 2001
Author(s)
Edward J. Garboczi, Nicos Martys, H A. Saleh, Richard A. Livingston
The shape of aggregates, from whatever source, plays a crucial role in determining the properties of the composite material in which they are embedded (e.g., asphaltic or portland cement concrete). To properly characterize this three-dimensional shape
