The rise in hydrogen fuel cell electric vehicles (FCEVs) is expected to pose a variety of hazards on the road. Vehicles using could cause significant damage, owing vapor cloud explosions, jet fires caused by leakage, or tank explosions. This risk further increase semi-enclosed spaces, such as underground parking lots and road tunnels. Therefore, it necessary study fire safety spaces. In this st...

Abstract Fuel cost is an important part of voyage cost, and fuel replenishment strategy decision affecting the operating benefit shipping companies. A mixed integer nonlinear programming model supply for LNG dual-fuel ships established to expand research scope in industry minimize cost. In this paper, genetic algorithm improved, solving steps are designed, validity verified by example analysis....
