To obtain the optimal load-reduction trailmaster challenger 200x scheme and calculation method of earth pressure on the crown of the pipe, the load-reduction efficiency of rigid pipe and flexible pipe with different thicknesses and layers of expanded polystyrene (EPS) is investigated by model tests, and the law of load reduction is obtained by anal
The article is devoted to the problems of using unmanned aircraft systems to extinguish fires in high-rise buildings with continuous supply of compression foam to the fire source.On the one hand, the use of compression foam with a continuous flow from ground source by unmanned aircraft is considered as one of the most promising ways of fighting fir
In order to solve the problem of difficulty campicon.com in achieving individual scheduling for large-scale electric vehicles entering the grid and the existence of "dimensionality disaster" in cluster scheduling, a hierarchical and partitioned optimization operation model for active distribution network based on vehicle-to-grid(V2G) mode is establ
