    Airport delay prediction model based on regional residual and LSTM network by Jingyi QU, Meng YE, Xing QU

    Published 2019-04-01
    “…Nowadays,the civil aviation industry has a high precision requirement of airport delay prediction,so an airport delay prediction model based on the RR-LSTM network was proposed.Firstly,the airport information,meteorological information and related flight information were integrated.Then,the RR-LSTM network was used to extract the features of the fused airport data set.Finally,the Softmax classifier was adopted to classify and predict the airport delay.The proposed RR-LSTM network model can not only extract the time correlation of airport delay data effectively,but also avoid the gradient disappearance problem of deep LSTM network.The experimental results indicate that the RR-LSTM network model has a prediction accuracy of 95.52%,which achieves better prediction results than the traditional network model.The prediction accuracy can be improved about 11% by fusing the weather information and the flight information of the airport.…”

    Communication and Security Integrated Space-Earth Heterogeneous Network Architecture by Xiaoning ZHANG, Lidong ZHU

    Published 2020-12-01
    “…To achieve the integration of space information networks and high-speed rail, ship and civil aviation private communication networks, this article proposes to leverage the mechanism of identifi er and locator separation to construct the communication and security integrated space-earth heterogeneous network architecture.The proposed network architecture included four network layers (i.e., space-earth heterogeneous network service layer, space-earth heterogeneous network traffi c layer, space-earth heterogeneous network routing layer and space-earth heterogeneous network access layer) and fi ve network identifi ers (i.e., service identifi er, traffi c identifi er, routing identifi er, access identifi er and host identifi er).With the method of effi cient network identifi er mapping, the communication and security integrated requirement for space information networks and ground private communication networks could be guaranteed.…”
