The space station is a dome-shaped structure with scale-shaped modules and basalt reinforced fiber composite materials, providing thermal insulation, ventilation and continuous power supply. It can provide support and guarantee for the real-time monitoring, recovery and information transmission of test data, and meet the basic work and life needs of test personnel.展开更多

Therefore, it is necessary for research staff to collect information, explore the actual situation of local people, understand the suitable environment for tea cultivation, correctly select the appropriate tea varieties, enhance the income of local residents from tea cultivation, promote local economic development, and contribute to the improvement of regional and individual economic level. This paper mainly discusses the cultivation management measures and key cultivation techniques of southern tea, understands the specific situation of management measures and analyzes the key cultivation techniques, in order to provide a certain reference value.展开更多

Through virtualization, multiple customized virtual networks(VNs), requested by users, are allowed to coexist on the underlying substrate networks(SNs). In addition, the virtualization scheme contributes to sharing underlying physical resources simultaneously and seamlessly. However, multiple technical issues still stand in the way of NV successful implementation. One key technical issue is virtual network embedding(VNE), known as the resource allocation problem for NV. This paper conducts a survey of embedding algorithms for VNE problem. At first, the NV business model for VNE problem is presented. Then, the latest VNE problem description is presented. Main performance metrics for evaluating embedding algorithms are also involved. Afterwards, existing VNE algorithms are detailed, according to the novel proposed category approach. Next, key future research aspects of embedding algorithms are listed out. Finally, the paper is briefly concluded.展开更多
