Given the limited driving range of battery electric vehicles and lack of sufficient charging infrastructure, locating charging stations is an important decision problem to enable long-distance travels by battery electric vehicles. This paper considers an important political factor in such location problems: the equitable access to charging stations among geographical regions. We propose three t...

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.

Electrification of the transportation sector has originated a worldwide demand towards green-based refueling infrastructure modernization. Global researches and efforts have been pondered to promote optimal Electric Vehicle (EV) charging stations. The EV power electronic systems can be classified into three main divisions: station configuration (e.g., Level 1 (i.e., slow-speed charger), 2 fast-...

Exposure to the aromatic hydrocarbon is a public health problem and threat to environment with proven harmful impact on humanity, including industrial workers and general population. Petrol station attendants are workers chronically exposed at least five year to petroleum derivatives primarily through inhalation of the volatile fraction of petrol during vehicle refueling. Significant include ha...

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...
