a system of information analysis centers dealing with the broader aspects of the National Measurement System; provides appropriate services to ensure that the NBS staff has optimum accessibility to the scientific information of the world. The Office

Atmospheric effects in astroparticle physics experiments and the challenge of ever greater precision in measurements

“…This effect is especially important to correct for cirrus since their structure function is more complex. Such an effect, associated to the fact that clouds move in the field of view during the time exposure, is currently investigated in [110]. The problematic is not the same for the detection of extensive air showers.…”

“…If a star is not observed, it is deduced that parts of a cloud hide it. Thanks to all-sky CCD cameras, it is possible to observe several hundreds of stars in the same image and to compute the spatial structure function of clouds (assuming the time exposure short compared to the distance travelled by clouds [110]). Corrections are applied to take into account the decrease of the camera sensitivity with the zenith angle due to the extinction in air masses.…”

Research considerations in computer networking to expand resource sharing

“…Economic Analyses of Networking [14]. Systematic study is needed of the overall cost of various computing services through networking, and of the potential effect on computing revenues of competitive networking operations.…”

“…Computer Communications Guidelines [2,[14][15][16] [16], and engineering analyses that guide the configuring of experimental networks. One useful result would be a catalog of interfacing requirements (hardware and software) of existing networks, and of "off-the-shelf" hardware and software for low-cost access arrangements among dispersed locations.…”
