    Survey on video image reconstruction method based on generative model by Yanwen WANG, Weimin LEI, Wei ZHANG, Huan MENG, Xinyi CHEN, Wenhui YE, Qingyang JING

    Published 2022-09-01
    “…Traditional video compression technology based on pixel correlation has limited performance improvement space, semantic compression has become the new direction of video compression coding, and video image reconstruction is the key link of semantic compression coding.First, the video image reconstruction methods for traditional coding optimization were introduced, including how to use deep learning to improve prediction accuracy and enhance reconstruction quality with super-resolution techniques.Second, the video image reconstruction methods based on variational auto-encoders, generative adversarial networks, autoregressive models and transformer models were discussed emphatically.Then, the models were classified according to different semantic representations of images.The advantages, disadvantages, and applicable scenarios of various methods were compared.Finally, the existing problems of video image reconstruction were summarized, and the further research directions were prospected.…”

    Meta model construction mechanism in SDN architecture by Bin ZHUGE, Hua ZHU, Baoxia WANG, Weiming WANG, Julong LAN

    Published 2016-11-01
    “…Micro service is a new method of modern application architecture,its characteristic is that decomposing the complex applications into discrete,independent service,so that decoupling of applications scheme can be achieved,and the individual service could be developed,deployed and extensioned independently.The change of the application must drive on the change of the underlying network,the architecture of reconfigurable fundamental information communication network aimd to compensate for the network business requirements and network transmission capacity through the network reconfiguration mechanism.A meta model construction mechanism with the SDN architecture for fusion the reconfiguration and software defined network technology was proposed,it aimed to present the services of each layer in the SDN architecture by the form of meta model.And after referencing the AKF scale cube,a kind of meta model building method based on orthogonal decomposition was proposed.Finally,the feasibility of meta model building method based on orthogonal decomposition from the theoretical analysis and development of example was verified.…”

    Performance evaluation on key techniques for 5G enhanced mobile broadband by Longchang ZHU, Xiaodong JI, Xinran ZHANG, Quxin LI

    Published 2020-01-01
    “…The 5G eMBB scenario puts high requirements on performance such as spectrum efficiency and system capacity.It was proposed to introduce technologies such as massive MIMO and millimeter-wave communication,and combine heterogeneous networks to improve system performance,because traditional technologies cannot bring about corresponding performance improvement.At the same time,there are few simulation evaluation results for the key technologies of the eMBB scenario,and the performance advantages of each technology cannot be explained from the perspective of simulation.The performance of massive MIMO with different antenna numbers by building a system-level simulation platform were evaluated,and the impact of the density and bias of micro BS in the mmWave frequency to the performance based on the results in the heterogeneous networks was summarized.It has great refer-ence value for parameter configuration and network construction of 5G network.…”

    Off-line emergency communication method of power internet of things based on edge computing by Donghong FU, Dan LIU, Guijun SHI, Anxin WANG, Chunxue FAN, Haijun WANG, Yiying ZHANG

    Published 2018-03-01
    “…A new multi-mode node was designed for the emergency communication with the demand of electricity.The node had the multi-mode communication capability of the private network and the public network technology,which could switch smoothly in three modes:the power private network,the wireless Ad Hoc network and the wireless public network.Data were automatically uploaded to the multi-mode terminal,multi-mode terminal through the mode of rapid switching,with the public network resources to achieve rapid network recovery and continuous transmission of data to achieve off-line emergency communications.Meanwhile,an intelligent routing algorithm based on smoothness was proposed,and the three principles of edge network communication were defined.Through the edge calculation method,the calculation and updating of the smoothness were realized to ensure the intelligent,efficient and reliable operation of the edge network in the offline state.…”

    Privacy protection mechanism of on-demand disclosure on blockchain by Shaozhuo LI, Na WANG, Xuehui DU

    Published 2020-06-01
    “…Privacy protection has become the key problem that blockchain technology must solve from theory to practice.There is a privacy protection requirement of on-demand disclosure in practical applications.Inspired by multicast secure communication mechanism,a privacy protection mechanism of on-demand disclosure on blockchain was proposed.This mechanism improves the RSA based anonymous multi receiver encryption scheme to realize the disclosure of the private data on the blockchain only to the permitted informed,the anonymity protection of the informed and the traceability of the privacy disclosure.The Quorum blockchain privacy protection mechanism is adopted to realize the safe and efficient distribution of the key between the owner of the private information and the informed.Finally,it is proved that PPM-ODB mechanism can guarantee the privacy of privacy data and its superiority in time and storage cost,and it is suggested that the number of informed people should be less than 100 to obtain a good user experience.…”

    Open-Source Urbanism: Creating, Multiplying and Managing Urban Commons by Karin Bradley

    Published 2015-06-01
    “…Although this tradition of ‘commoning’ is not new, it is currently being reinvented with the use of digital technologies. Combining Elinor Ostrom’s analysis of self-managed natural resource commons with Yochai Benkler’s assertion that commons-based peer production constitutes a ‘third mode of production’ that lies beyond capitalism, socialism and their blends, I argue that open-source urbanism critiques both government and privately-led urban development by advancing a form of postcapitalist urbanism.…”
