Special Issue on Collaborative Engineering

Author(s)
Ram D. Sriram, Simon Szykman, D Durham
Design of complex engineering systems is increasingly becoming a collaborative task among designers or design teams that are physically, geographically, and...

Power Control in Multihop CSMA

Author(s)
Hamid Gharavi, Bo Yan
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the...

The 2006 Upper Ontology Summit Joint Communique

Author(s)
Leo Obrst, Patrick Cassidy, Steven R. Ray, Bradford Smith, Dagobert Soergel, Matthew West, Peter Yim
On March 14-15 in Gaithersburg, MD, at the US National Institute of Standards and Technology (NIST), the Upper Ontology Summit (UOS) took place. The Upper...

Microfabricated atomic clocks and magnetometers

Author(s)
Svenja A. Knappe, P Schwindt, Vladislav Gerginov, V Shah, Hugh Robinson, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John Moreland
We demonstrate the critical subsystems of compact atomic clocks and magnetometers based on microfabricated physics packages. The clock components have a volume...

X-Ray and Neutron Powder Diffraction Studies of (Ba1-xSrx)Y2CuO5

Author(s)
Zhi Yang, Winnie K. Wong-Ng, James A. Kaduk, Qingzhen Huang, Lawrence P. Cook
This paper reports the results of the crystallography and crystal chemistry investigation of the (Ba1-xSrx)Y2 CuO5 ( green phase ) solid solution series by x...

Soft magnetic layers for low-field-detection magnetic sensors

Author(s)
William F. Egelhoff Jr., Robert McMichael, Cindi L. Dennis, Mark D. Stiles, Freemon Johnson, Alexander J. Shapiro, Brian B. Maranville, Cedric J. Powell
We have investigated a wide variety of soft magnetic layers as sense layers for magnetic-field sensors. We find that in thin-film form, some of these soft...

Direct Observation of the 2d3/2 - 2d5/2 Ground State Splitting in Xe9+

Author(s)
E Takacs, B Blagojevic, K Makonyi, E O. LeBigot, Csilla Szabo-Foster, Yong Sik Kim, John D. Gillaspy
We have used the NIST Electron Beam Ion Trap to observe a visible line at 598.30(13) nm that corresponds to the 4d9 2D3/2 - 4d9 2D5/2 magnetic dipole transition...

Fatigue Resistant Miniature Piezoceramic Actuators

Author(s)
Stephanie A. Hooker, Jens Mueller, Clayton Kostelecky, K. Womer
