Strategy and Modeling for Building DR Optimization

Author(s)
Richard Lau, Sami Ayyorgun, Siun Chuon Mau, Archan Misra, David Holmberg, Steven T. Bushby
While it is well recognized that renewable microgrid generation and intelligent storage can significantly reduce a building's need for grid power and its peak

Real-time Feedback for Usable Fingerprint Systems

Author(s)
Mary F. Theofanos, Brian C. Stanton, Yee-Yin Choong, Haiying Guan
Compared with traditional password and other identification methods, biometrics like face, iris, and fingerprint for automatic personal identification

Dual-comb-based characterization of rapidly tuned lasers

Author(s)
Fabrizio R. Giorgetta, Esther Baumann, Ian R. Coddington, William C. Swann, Nathan R. Newbury, Zeb W. Barber, Peter Roos
We demonstrate a technique to calibrate the instantaneous frequency versus time from a rapidly tuned cw laser. Our dual-comb-based spectrometer can measure

Carbon nanotube arrays for absolute IR and THz radiometry

Author(s)
John H. Lehman, Kerry N. Betz, Erich N. Grossman
We have assembled and evaluated a novel electrically calibrated thermopile having an array of 1.5 mm long multiwalled carbon nanotubes as the radiation absorber

5754 Aluminum Sheet Deformed Along Bi-Linear Strain Paths

Author(s)
Mark A. Iadicola, Lin Hu, Anthony D. Rollett, Timothy J. Foecke
Sheet specimens of aluminum alloy 5754 were deformed along a series of bi-linear, equal-biaxial and uniaxial, strain paths while simultaneously measuring stress

Service Life Prediction for Sealants

Author(s)
Christopher C. White, Donald L. Hunston, Kar T. Tan, James J. Filliben
Previous industry consensus postulated that four elements of the weather: Temperature, Humidity, Ultraviolet Radiation, and Mechanical loading were responsible

An Iterative Algorithm for Calculating Stylus Radius Unambiguously

Author(s)
Theodore V. Vorburger, Xiaoyu A. Zheng, Thomas B. Renegar, Jun-Feng Song, Li Ma
The stylus radius is an important specification for stylus instruments and is commonly provided by instrument manufacturers. However, it is difficult to measure

A Laser-Cooled Frequency Standard for GPS

Author(s)
Thomas P. Heavner, Stephan E. Barlow, Marc A. Weiss, Neil Ashby, Steven R. Jefferts
NIST is in an initial phase of developing a prototype laser-cooled atomic frequency standard (AFS) for potential use in a future GPS system. The expected
