The GOES time code service, 1974-2004: a retrospective.(Geostationary Operational Environmental Satellites)
March 1, 2005... NIST ended its Geostationary Operational Environmental Satellites (GOES) time code service at 0 hours, 0 minutes Coordinated Universal Time (UTC) on January 1, 2005. To commemorate the end of this historically significant service, this article...

A summary of heat-flux sensor calibration data.(research of heat-flux sensors)
March 1, 2005... This paper presents a statistical evaluation of the responsivity data on a number of heat-flux sensors, calibrated using an electrical substitution radiometer as a transfer standard up to 5 W * [cm.sup.-2]. The sensors, furnished by the...

Quantitating fluorescence intensity from fluorophore: assignment of MESF values.(molecules of equivalent soluble fluorophore)
March 1, 2005... A procedure is presented to convert the comparison of measured fluorescence signals into a comparison of fluorescence yields (FY). The fluorescence yield, which is a property of a solution or a suspension, is defined as the product of the...

Ba(OH)[.sub.2] equilibria in the system Ba-O-H-F, with application to the formation of [Ba.sub.2]Y[Cu.sub.3][O.sub.6.5 + x] from Ba[F.sub.2]-precursors.
March 1, 2005... The ex situ process for fabricating [Ba.sub.2]Y[Cu.sub.3][O.sub.6.5 + x] superconducting tapes from Ba[F.sub.2]-based precursors involves a hydration/oxidation reaction at [approximately equal to]730[degrees]C to 750[degrees]C generally written...

Hamiltonian paths through two- and three-dimensional grids.
March 1, 2005... This paper address the existence of Hamiltonian paths and cycles in two-dimensional grids consisting of triangles or quadrilaterals, and three-dimensional grids consisting of tetrahedra or hexahedra. The paths and cycles may be constrained to...
