Nearly 400 Tycho-2 stars have been observed in a 720 square degree field in the direction of the North Galactic Pole with the high resolution echelle spectrograph ELODIE. Absolute magnitudes, effective temperatures, gravities and metallicities have been estimated, as well as distances and 3D velocities. Most of these stars are clump giants and span typical distances from 200 pc to 800 pc to the...

Analyses of satellite, ground-based, and balloon measurements allow updated estimates of trends in the vertical profile of ozone since 1979. The results show overall consistency among several independent measurement systems, particularly for northern hemisphere midlatitudes where most balloon and ground-based measurements are made. Combined trend estimates over these latitudes for the period 19...

Laser Doppler Velocimetry (LDV) has been employed to determine pseudo-turbulence characteristics of the flow field around bubble train forming in non-Newtonian caboxymethylcellulose (CMC) aqueous solution at low gas flow rate condition. The Reynolds stress and turbulent intensity of the liquid were investigated by means of Reynolds time-averaged method. The experimental results show that ax...

The incremental sheet metal forming (ISMF) process is a new and flexible method that is well suited for small batch production or prototyping. This paper studies the use of the finite element method in the incremental forming process of AA1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

Abstract The large particle mass flux profile measurement at heights from 0.125 to 16 m and parameters of the size distribution function received by O.E. Semenov on desertificated areas in Aral region were analyzed. technique has been worked out for height characteristic retrieving. aleurite number concentration profiles with sizes less than 50, 73 100 μm sand have retrieved. Power-law approxim...

One advantage of smart grids is that they can reduce the peak load by distributing electricity-demands over multiple short intervals. Finding a schedule that minimizes the peak load corresponds to a variant of a strip packing problem. Normally, for strip packing problems, a given set of axis-aligned rectangles must be packed into a fixed-width strip, and the goal is to minimize the height of th...

Stream morphology is an important indicator for revealing the geomorphological features and evolution of Yangtze River. Existing studies on River focus planar features. However, vertical are also important. Vertical mainly control flow ability erosion intensity. Furthermore, traditional often a few stream profiles in linked together by runoff nodes, thus affecting naturally. In this study, clus...

The HYSPLIT_4 (HYbrid Single-Particle Lagrangian Integrated Trajectory) model is designed for quick response to atmospheric emergencies, diagnostic case studies, or climatological analyses using previously gridded meteorological data. Calculations may be performed sequentially on multiple meteorological grids, going from fine to coarse resolution using either archive or forecast data fields. Ai...

Wepresent a detailed study of a statistically complete sample of highly inclined disk galaxies in the near-infraredK ′ band. Since theK ′-band light is relatively insensitive to contamination by galactic dust, we have been able to follow the vertical light distributions all the way down to the galaxy planes. Themean levels for the sharpness of theK ′-band luminosity peaks indicate that the vert...

The study investigated the composition and content of Σ15PAH in surface core sediments from Dachan Bay (DCB) Shenzhen city discussed effects urban development regional energy structure on marine environment through spatial distribution, vertical profile, sources Σ15PAH. results indicated that concentrations DCB ranged between 299 ng/g 2336 65 994 sediments. horizontal distribution PAHs with dec...
