Control Fusion for Safe Multi-robot Coordination

May 9, 2014
Author(s)
Roger V. Bostelman, Jeremy A. Marvel
Future smart manufacturing systems will include more complex coordination of mobile manipulators (e.g., robot arms mounted on mobile bases). The National Institute of Standards and Technology, Performance of Collaborative Robot Systems Project has been

Compressed-liquid Density Measurements of Three Alternative Turbine Fuels

February 7, 2014
Author(s)
Stephanie L. Outcalt
Compressed-liquid densities of three alternative turbine fuels have been measured. The measurements were made from 270 K to 470 K, and 0.5 MPa to 50 MPa. The data have been correlated with a Tait equation, and parameters are given for each fuel. Results of

Composition-Explicit Distillation Curves of Alternative Turbine Fuels

December 3, 2013
Author(s)
Raina V. Gough, Thomas J. Bruno
In recent years, environmental considerations, the potential for supply disruptions, and rising fuel prices have led to the development of turbine fuels produced from non-petroleum feedstocks. To determine the suitability of an alternative turbine fuel, it

FATIGUE CRACK GROWTH OF TWO PIPELINE STEELS IN A PRESSURIZED HYDROGEN ENVIRONMENT

October 22, 2013
Author(s)
Andrew J. Slifka, Elizabeth S. Drexler, Nicholas Nanninga, Yaakov Levy, Joseph D. McColskey, Robert L. Amaro
Fatigue crack growth tests were conducted on two pipeline steel alloys, API 5L X52 and X100. Baseline tests were conducted in air, and those results were compared with tests conducted in pressurized hydrogen gas. All tests were run at (load ratio) R = 0.5

Fatigue Crack Growth Modeling of Pipeline Steels in High Pressure Gaseous Hydrogen

October 21, 2013
Author(s)
Robert L. Amaro, Elizabeth S. Drexler, Andrew J. Slifka
Hydrogen will likely play a key role in a future clean energy economy. However, fundamental understanding of the deleterious effects of hydrogen on the fatigue and fracture properties of pipeline steels is lacking. Furthermore, engineering tools for design

Forensic Science Laboratories: Handbook for Facility Planning, Design, Construction, and Relocation.

June 25, 2013
Author(s)
James Aguilar, Tom Barnes, Joseph Browne, Yvette Burney, John Byrd, Bonnie Carver, Adam Denmark, Susan Halla, Lou Hartman, Alison Kennedy, Deborah Leben, Greg Matheson, Jim McClaren, Russell McElroy, Romeo Miranda, Kenneth Mohr, Michael Mount, Steve Sigel, Jennifer Smither, Melissa Taylor, Aliece Watts, Shannan Williams
This handbook is a resource for laboratory directors, designers, consultants, and other stakeholders involved in the construction or major renovation of forensic science laboratories. Laboratory construction and renovation projects must meet the unique

Thermal Decomposition Kinetics of 1,3,5-Triisopropylcyclohexane

May 29, 2013
Author(s)
Raina V. Gough, Jason A. Widegren, Thomas J. Bruno
Recent surrogate diesel fuel mixture development identified the need for a multiply-substituted, low cetane number, high molecular mass monocycloalkane component. On the basis of a thermophysical property evaluation and prediction, 1,3,5

Thermal Decomposition of 1-Pentyl Radicals at High Pressures and Temperatures

September 27, 2012
Author(s)
Andrea Comandini, Iftikhar A. Awan, Jeffrey A. Manion
Complementary shock-tube studies at the National Institute of Standards and Technology (NIST) and the University of Illinois at Chicago (UIC) have been used to examine the decomposition reactions of the 1-pentyl radical at temperatures of 833 K to 1130 K
