The International State of Building System Commissioning

August 17, 2008
Author(s)
Natascha S. Milesi-Ferretti, Nobuo Nakahara, Harunori Yoshida
Buildings are a major and growing source of energy consumption and as such, contribute to the significant problems associated with energy dependence and growing environmental impacts. Building system commissioning is a quality assurance process designed to

Capillary flow meter for calibrating spinning rotor gauges

August 6, 2008
Author(s)
Robert F. Berg
This article describes a capillary flow meter whose maximum flow rate of 0.2 micromol/s (~0.2 cm3/min at ambient conditions) covers the range that is useful for calibrating spinning rotor gauges. Knowing the input pressure, output pressure, and temperature

Qian Dong, Andrei F. Kazakov, Chris D. Muzny, Robert D. Chirico, Jason A. Widegren, Vladimir Diky, Joe W. Magee, Kenneth N. Marsh, Michael D. Frenkel
Ionic Liquids Database (ILThermo)is a free web research tool that allow users worldwide to access an up-to-data data collection from the publications on experimental studies of thermodynamic and transport properties of ionic liquids, as well as binary and

Radiation Properties of IR Calibrators With V-Grooved Surfaces

April 1, 2006
Author(s)
Leonard M. Hanssen, A Prokhorov, Sergey Mekhontsev
Use of linear or concentric grooves is a well-known approach for increasing the surface emissivity to enable the construction of compact blackbody radiators, improve absorptance of stray radiation traps, baffles and thermal radiation detectors, as well as

Experiments Toward Non-Contact Safety Standards for Automated Industrial Vehicles

April 1, 2005
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Rajmohan Madhavan
The performance evaluation of an obstacle detection and segmentation algorithm for Automated Guided Vehicle (AGV) navigation in factory-like environments using a new 3D real-time range camera is the subject of this paper. Our approach expands on the US

International Comparisons of Femtosecond Laser Frequency Combs

April 1, 2005
Author(s)
Long-Sheng Ma, Zhiyi Bi, A Bartels, Lennart Robertsson, Massimo Zucco, Robert Windeler, G Wilpers, Christopher W. Oates, Leo W. Hollberg, Scott A. Diddams
Two types of international comparisons of femtosecond laser frequency combs have been performed in France and the USA. Five combs were involved in the comparisons. Three combs, of which two are transportable, employ nonlinear photonic crystal fiber (PCF)

Flammability of Nanocomposites-Effects of the Shape of Nanoparticles

January 1, 2005
Author(s)
Takashi Kashiwagi
Nanocomposites based on three different shapes of nanoscale particles, sphere (silica), plate (clay), and tube (carbon nanotube), were prepared and the dispersion of the particles in the nanocomposites was confirmed by various techniques using TEM, SEM

Refrigeration for Superconductors

September 20, 2004
Author(s)
Ray Radebaugh
Temperatures in the range of 0.05 to 80 K are required for most applications of superconductors. Refrigeration powers range from fractions of a watt for many electronic applications to kilowatts for some large magnet and power applications. This paper

Multiplexed Assays for Evaluation of Y-SNP Markers in U.S. Populations

April 1, 2004
Author(s)
Peter Vallone, John Butler
Genetic markers located on the Y chromosome are of increasing importance in human identity testing. In an effort to evaluate the forensic utility of Y chromosome single nucleotide polymorphism (SNP) markers, we constructed several novel multiplex allele
