• Information and Communications Technology and Policy. 2021, 47(4): 38-42. DOI:10.12267/j.issn.2096-5931.2021.04.007
• Abstract ( 358 ) 　　
• Based on the basic theory, a phase change refrigeration cycle system from cabinet to outdoor environment is constructed, which uses gas pump, liquid pump, evaporation condensation, gravity heat pipe technology and so on. This system can transport the heat from the server to the outdoor environment efficiently and there is no intermediate heat exchange in the whole process. Therefore, this system can minimize the difference between evaporation temperature and condensation temperature. The test results show that the cooling system annual average energy efficiency ratio can be above 20 when it is used in the national core city data center. At the same time, the system also has the advantages of high peak energy efficiency, applicability and compatibility, which further reduces the construction and operation costs of the data center.

• Abstract ( 320 ) 　　
• The amount of users who pay close attention to some project on a certain scale is one of the important evaluation parameters to analyze the development of the industries in which these projects are located. It is the basic data to research the trend of industry development. But it is difficult to obtain the information of the projects in most cases and it has motivated a research to relax this requirement with a data acquisition and analysis system which has been designed and implemented. The system performs multi-dimensional analysis on changes of the objects including the quantity and the attention based on the number of stars, forks and issues related to the key projects obtained from GitHub. To be more intuitive, data visualization realized by Baidu Echarts provides a reference for studying the overall trend of industry development.

• Abstract ( 484 ) 　　
• Aiming to mitigate the training difficulty of deep neural models at the edge of network, this paper introduces a deep learning model training framework based on 5G edge computing. The presented training framework connects smart devices and performs data communication via the 5G edge computing access network. The model training is firstly implemented in edge computing nodes using local data, and then the model parameters are collected and globally updated in the central server. This scenario ensures the diversity of data sets for training, reduces network􀆳s pressure and protects privacy of local data. Thus, it is a promising edge computing architecture for deep learning.
