    Time and Space View of Human-Water Relationship Discipline and Its Research Methods by ZUO Qiting

    Published 2022-01-01
    “…The research object of the human-water relationship discipline is the human-water system composed of nature and human society.It has distinct time and space properties and will inevitably encounter problems of temporal and spatial scales.Therefore,it is of great significance to study and clarify the time and space view of the human-water relationship discipline.On the basis of the previous research and common examples,this paper expounds the temporal and spatial scales of research on the human-water relationship.Then,we put forward the time and space view of the human-water relationship discipline and discuss its main arguments and application approaches.After that,we introduce the research methods of the spatiotemporal analysis of the human-water relationship, which mainly include three categories,i.e.…”

    Research on Dynamic Virtualization Distributed Mobility Management Method for LEO Satellite Network by Hongtao ZHU, Qing GUO

    Published 2020-09-01
    “…With the commercialization of 5G,the integration of satellite communication and ground 5G has become a key research direction in the industry.Low earth orbit satellite network can cover the whole world and communicate with anyone at any time and anywhere.It is an eff ective supplement and expansion of terrestrial cellular network.Especially,the deployment of low earth orbit (LEO) internet constellation such as OneWeb and Starlink accelerates the development of LEO satellite network.However,due to the high dynamic of LEO satellite and the fast change of its network topology,the network management problem caused by it has become the diff culty of LEO satellite application,and mobility management is one of the key technologies.How to build a mobility management mechanism suitable for high dynamic LEO satellite network is an urgent problem to be solved.Based on the idea of ground distributed gateway and satellite agent cluster,the dynamic virtualization distributed mobility management (DV-DMM) model was proposed,which was mainly used to solve the problems of poor scalability and single point failure of traditional mobility management.At the same time,it used satellite to build virtual gateway to solve the problem of building satellite ground station on the ground.…”

    Research of duality and multi-level security model based on intransitive noninterference theory by LIU Wei-peng1, ZHANG Xing2

    Published 2009-01-01
    “…A novel duality and multi-level security model(DMLSM) based on intransitive noninterference theory was proposed,which protects confidentiality of information based on BLP model and integrity based on Biba model.To en-hance the usability of model,it introduces confidentiality trusted domain and integrality trusted domain which check the operations that violate the security policy in confidentiality check-room or integrity check-room respectively,then allow or refuse the access.The strict formal description of the model based on intransitive noninterference theory of informa-tion flow is given;furthermore,it proves the security of the model.The implementation of the model in Linux operating system is discussed and the application of model in practice is also demonstrated.The research gives Some contributes on the protection for sensitive important information and national information content security infrastructure.…”
