Fire as a Building Load

February 19, 2017
Author(s)
Richard W. Bukowski
The concept of designing buildings to resist loads is fundamental to the design and regulatory process. Fire has traditionally been addressed differently because fires are difficult to describe in the same way as other building loads. This paper proposes a

Release of NIST SP 800-147B, BIOS Protection Guidelines for Servers

October 29, 2014
Author(s)
Andrew R. Regenscheid, Larry Feldman, Gregory A. Witte
Modern computers rely on fundamental system firmware, commonly known as the Basic Input/Output System (BIOS), to enable system components to communicate and work together. The BIOS is typically developed by both original equipment manufacturers (OEMs) and

Shear Induced Tilt Order in Polymer Blends

October 16, 2008
Author(s)
Erik K. Hobbie, Haonan Wang, H Jeon, H W. Kim, D Stout, Charles C. Han
Optical studies of viscoelastic emulsions under simple shear flow reveal long-range spatial correlation in the orientation of the deformed domains. As the volume fraction of droplets increases, the tilt angle between the direction of orientation and the

Extraction of Sheet Resistance and Linewidth from All-Copper ECD Test-Structures Fabricated from Silicon Preforms

March 22, 2007
Author(s)
Byron J. Shulver, Andrew S. Bunting, Alan Gundlach, Les I. Haworth, Alan W. Ross, A. J. Smith, Anthony J. Snell, J. T. Stevenson, Anthony Walton, Michael W. Cresswell, Richard A. Allen
Test Structures for the extraction of Electrical Critical Dimensions (ECD) and having all-copper features with no barrier metal films have been fabricated. The advantage of this approach is that electrical measurements provide a non-destructive method for

Polymerization Transition in Two-Dimensional Systems of Dipolar Spheres

January 1, 2005
Author(s)
Justin Stambaugh, K VanWorkum, Jack F. Douglas, Wolfgang Losert
We investigate the self-organization of dipolar spheres into polymer chains as a fundamental model of self-assembly of particles having anisotropic interactions. Our study involves a combination of simulation and experiments on vertically vibrated magnetic

Mode-Locked and Single-Frequency Er/Yb Co-Doped Waveguide Lasers

January 1, 2003
Author(s)
John B. Schlager, Berton Callicoatt, Richard Mirin, Norman Sanford
Erbium/ytterbium co-doped planar waveguide lasers are fabricated for low-jitter mode-locked operation and single-frequency operation at 1.54 υm. The passively mode-locked lasers produce picosecond pulses at fundamental repetition rates up to 1 GHz with

The Philosophy of Information Retrieval Evaluation

January 1, 2002
Author(s)
Ellen M. Voorhees
Evaluation conferences such as TREC, CLEF, and NTCIR are modern examples of the Cranfield evaluation paradigm. In the Cranfield paradigm, researchers perform experiments on test collections to compare the relative effectiveness of different retrieval

Evaluation conferences such as TREC, CLEF, and NTCIR are modern examples of the Cranfield evaluation paradigm. In the Cranfield paradigm, researchers perform experiments on test collections to compare the relative effectiveness of different retrieval

OOF: An Image-Based Finite Element Analysis of Material Microstructure

June 1, 2001
Author(s)
Stephen A. Langer, W Carter, Lin-Sien H. Lum
The determination of macroscopic properties of a material given its microscopic structure is of fundamental importance to materials science. We present an overview of two public domain programs which jointly predict macroscopic behavior, starting from an

Dimensional Inspection Planning Based on Product Data Standards

March 19, 1994
Author(s)
Shaw C. Feng
An international standard on product data representation and exchange for dimensional inspection planning is being developed. This paper provides a review of fundamental technology enabling the standard development and describes the current status of an

Observation of a promethium complex in solution

May 22, 2024
Author(s)
Bruce D. Ravel, Darren Driscoll, Frankie White, SUBHAMAY PRAMANIK, Jeffrey Einkauf, Dmytro Bykov, Santanu Roy, Richard Mayes, Laetitia Delmau, Samantha Schrell, Thomas Dyke, April Miller, Matt Silveira, Silveira2 van Cleve, Roy Copping, Sandra Davern, Santa Jansone-Popova, Ilja Popovs, Alexander Ivanov
Lanthanide rare earth metals are ubiquitous in modern technologies, but we know little about chemistry of the 61st element, promethium (Pm), a lanthanide which is highly radioactive and inaccessible. Despite its significance, Pm has conspicuously been

Steady State Vapor Bubble in Pool Boiling

February 3, 2016
Author(s)
An Zou, Ashish Chanana, Amit Agrawal, Peter C. Wayner, Jr., Shalabh C. Maroo
Boiling, a dynamic and multiscale process, has been studied for over five decades; however, a comprehensive understanding of the process is still lacking. The bubble ebullition cycle, which involves nucleation, growth and departure, happens over a very

Topological Robustness of Transport Statistics for Photons in a Synthetic Gauge Field

August 20, 2014
Author(s)
Sunil Mittal, Jingyun Fan, Sanli Faez, Alan L. Migdall, Jacob M. Taylor, Mohammad Hafezi
Electronic transport through a disordered medium leads generically to localization, where conductance drops exponentially with system size, even at zero temperature. The addition of gauge fields to disordered media leads to fundamental changes in transport

Creation of a six-atom Schrodinger cat state

December 1, 2005
Author(s)
Dietrich G. Leibfried, Emanuel H. Knill, Signe Seidelin, Joseph W. Britton, Brad R. Blakestad, J Chiaverini, David Hume, Wayne M. Itano, John D. Jost, C. Langer, R Ozeri, Rainer Reichle, David J. Wineland
Among highly entangled states of multiple quantum systems, Schrödinger cat states are particularly useful. Cat states are equal superpositions of two maximally different quantum states. They are a fundamental resource in fault-tolerant quantum computing

NIST Atomic and Molecular Databases on the World Wide Web

August 1, 1998
Author(s)
Robert A. Dragoset, Peter J. Mohr, Karen J. Olsen, Edward B. Saloman, G G. Wiersma, D Zucker
The Physics Laboratory of the National Institute of Standards and Technology is using the world wide web to disseminate the physical reference data it has been producing and/or evaluating. Web databases have been developed, each with an interface specially

Development of Publicly Available Forensic DNA Sequence Mixture Data
