    Multi-component Runoff Simulation in Arid Area Based on BP Neural Network by HAN Zichen, WANG Yi, HE Bin

    Published 2021-01-01
    “…The surface runoff of inland rivers in arid area of Northwest China is a valuable available water resource.However,due to the complexity of runoff composition,runoff simulation is complex,and it is difficult to actually utilize the water resources.This paper applies the back-propagation (BP) neural network combined with the degree-day factor of snowmelt runoff model (SRM) to analyze and simulate the runoff process of Kaidu River Basin in Xinjiang.The results show that:①The simulation accuracy is high.The daily average temperature is the main factor affecting the runoff and process in the target river basin.②Using autocorrelation coefficient method to process daily average flow series can significantly improve the simulation accuracy of annual average daily runoff,especially for daily runoff in the snow melting period (March to May) of target river basin that cannot be effectively simulated by ordinary input.This study provides a new way for the rapid simulation of runoff supplied by glacier,snow melting and precipitation in arid area of Northwest China,and an effective reference for rational utilization of water resources.…”

    Research on new frameworks and key technologies for intelligent emergency command communication networks by Li WANG, Aiguo FEI, Ping ZHANG, Lianming XU

    Published 2023-06-01
    “…The new generation of emergency command communication network is the basic means and important support for enhancing China’s emergency response capabilities such as national natural disasters and accidents, and is a key component of establishing a scientific emergency management technology system.Focusing on the requirements of communication, navigating, and sensing capabilities in “intelligent emergency”, a theoretical method and framework for intelligent emergency command and communication networks was proposed, which was introduced from three aspects in terms of network deployment, resource allocation, and assisted decision-making.The difficulties and technical ideas of multi-objective dynamic network deployment for communication, navigating, and sensing, multi-dimension efficient resource allocation for communication, computation, and caching, and multi-level decision-making and intelligent enhancement with cloud-edge-terminal collaboration were analyzed and discussed.It provides theoretical methods and key technical supports for building a new generation of emergency command and communication network in China.…”
