The transport of angular momentum due to neutral atoms in the tokamak edge is calculated and shown to be sensitive to the poloidal location of the neutrals. In the absence of external momentum sources, the edge plasma is predicted to rotate spontaneously in the opposite direction to the plasma current, at a speed proportional to the radial ion temperature gradient. If the plasma is collisional,...

Research on fuel cell hydrogen refueling stations is mostly concentrated newly-built stations, and there are few studies the combined CNG stations. The construction plan of conducive to planning layout, solving difficulties in land use reducing investment operating costs. This paper analyzes feasibility station construction, scale station, proposes its general layout plan.

The giant galaxies located at the centers of cluster cooling flows are frequently sites of vigorous star formation. In some instances, star formation appears to have been triggered by the galaxy’s radio source. The colors and spectral indices of the young populations are generally consistent with short duration bursts or continuous star formation for durations ≪ 1 Gyr, which is less than the pr...

optimally in a “reasonable” amount of time. NonetheWe describe the synthesis of efficient schedulers for planned shutdowns of power plants for refueling and maintenance (outages), using an automated programming tool, KIDS. Currently, the utility industry has no automated tools to generate schedules that are both safe and resource-efficient. We focused on safety constraints since they are critic...
