Battery swapping is a promising technology when compared with the traditional electric vehicle charging stations. The time spent at battery station might be similar to filling station. article presents information on attempts implement this solution, methods of swapping, infrastructure and operation stations, as well benefits key challenges technology.

in other to evaluate grain yield, rate and effective grain filling period of four barley (hordeum vulgaris l.) cultivars in different planting dates, a factorial experiment based on a randomized complete block design was conducted in the islamic azad university of ardabil research station in 2009. the treatments applied were: three levels of different planting dates (september, 23; october, 16 ...

Dam is set in large hydropower station. Cushion pool built behind the dam for flood discharge and energy dissipation of reservoir. Operation some time, dewatering structure safety which study, then cushion filled. Temporary dewater filled system used by previous engineer, but arranged controlled hard. Based on need filling, an example Baihetan station, necessity feasibility are study. Then a pe...

In order to explore the basic events and risk occurrence probability of fire explosion accidents in CNG (Compressed Natural Gas) filling station, a corresponding Bayesian network model was established based on fault tree station. The prior modified by introducing fuzzy mathematics process transforming into network, posterior station analyzed calculated GeNIe software. Finally, through case anal...
