New radiative lifetimes, measured by time-resolved laser-induced fluorescence spectroscopy, are reported for five Rydberg states of singly ionized ytterbium. Free Yb+ ions were produced in a laser-induced plasma. The experimental results have been compared with HFR calculations, taking core-polarization effects into account, and a good agreement (within 25%) between theory and experiment is observed for four levels. HFR results are also proposed for np (n less than or equal to 7) and nf (n less than or equal to 8) Rydberg states and compared with available data. [less ▲]

Chargée, dès 1997, à préparer et à mettre en œuvre les responsabilités nouvelles des universités francophones de Belgique dans le cadre de la coopération universitaire au développement, la C.U.D. n’a cessé d’identifier, de définir, d’adapter, d’affiner ses orientations stratégiques. Ce processus a été celui d’un apprentissage continu : de nombreuses évaluations internes à la C.U.D., et à ses groupes de travail, une concertation continue avec les autorités publiques, le relais des institutions universitaires du sud, ont permis à la C.U.D. de consolider, tout au long de l’actuel plan quinquennal 1998-2002, les orientations stratégiques qui guident ses programmes et qui constitueront la base des travaux du prochain plan quinquennal. Dans la présente contribution, sont décrites très brièvement les principales orientations stratégiques qui servent de lignes directrices à la C.U.D. [less ▲]

Within the German Research Initiative INVENT, the partial project „Verkehrliche Wirkung, Recht und Akzeptanz (VRA)“ deals with traffic effects, legal aspects, acceptance and economics of driver assistance systems. The major focus is to accompany the development of such systems rather than evaluating the systems at a later stage. This ensures that wrong development paths are avoided from the beginning. This presentation gives examples for the consulting services of VRA as well as for the early simulations of a driver assistance system. Such simulations vary in scale from basic functions to driving situations, then to traffic situations and finally to traffic scenarios. Results are presented for the basic functions and driving situations for a stop-and-go extension of adaptive cruise control. [less ▲]

We present results from a Chandra observation of the NGC 346 cluster. This cluster contains numerous massive stars and is responsible for the ionization of N66, the most luminous H II region and the largest star formation region in the SMC. In this first paper we will focus on the characteristics of the main objects of the field. The NGC 346 cluster itself shows only relatively faint X-ray emission (with L-X(unabs) similar to 1.5x10(34) ergs s(-1)), tightly correlated with the core of the cluster. In the field also lies HD 5980, a luminous blue variable star in a binary (or possibly a triple) system that is detected for the first time at X-ray energies. The star is X-ray bright, with an unabsorbed luminosity of L-X(unabs) similar to 1.7x10(34) ergs s(-1), but needs to be monitored further to investigate its X-ray variability over a complete 19 day orbital cycle. The high X-ray luminosity may be associated either with colliding winds in the binary system or with the 1994 eruption. HD 5980 is surrounded by a region of diffuse X-ray emission, which is a supernova remnant. While it may be only a chance alignment with HD 5980, such a spatial coincidence may indicate that the remnant is indeed related to this peculiar massive star. [less ▲]

Version 3 of the Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment data set for some 30 trace and minor gas profiles is available. From the IR solar-absorption spectra measured during four Space Shuttle missions (in 1985, 1992, 1993, and 1994), profiles from more than 350 occultations were retrieved from the upper troposphere to the lower mesosphere. Previous results were unreliable for tropospheric retrievals, but with a new global-fitting algorithm profiles are reliably returned down to altitudes as low as 6.5 km (clouds permitting) and include notably improved retrievals of H2O, CO, and other species. Results for stratospheric water are more consistent across the ATMOS spectral filters and do not indicate a net consumption of H-2 in the upper stratosphere. A new sulfuric-acid aerosol product is described. An overview of ATMOS Version 3 processing is presented with a discussion of estimated uncertainties. Differences between these Version 3 and previously reported Version 2 ATMOS results are discussed. Retrievals are available at http://atmos.jpl.nasa.gov/atmos. (C) 2002 Optical Society of America.
