    Realization of 10bit, 200MHz sampling frequency CMOS video D/A converter with gradient error compensation by HUANG Jiao-ying1, HE Yi-gang1 YANG Hui1, TANG Sheng-xue1, SHEN Fang1

    Published 2007-01-01
    “…A circuit of 10bit,200MHz sampling frequency current steering DAC with hierarchical symmetrical switching sequences was presented,which compensate the gradient error.The DAC employs segmented architecture.An integral linearity error caused by error distributes of current sources was reduced by a new switching sequence called "hierarchi-cal symmetrical switching".The DAC was built in a video-rate adaptive equalizer IC,which was fabricated in a 0.35μm,3.3V CMOS process.The area of DAC is 1.26mm×0.78mm.When operating at 14.318 MHz(4Fsc) sampling freguency,the effective numbers of bits is 9.3.Both the integral and the differential linearity errors are less than ± 0.5LSB.…”

    Neural Pathways Conveying Novisual Information to the Visual Cortex by Wen Qin, Chunshui Yu

    Published 2013-01-01
    “…The visual cortex has been traditionally considered as a stimulus-driven, unimodal system with a hierarchical organization. However, recent animal and human studies have shown that the visual cortex responds to non-visual stimuli, especially in individuals with visual deprivation congenitally, indicating the supramodal nature of the functional representation in the visual cortex. …”

    Maritime mobile edge computing offloading method based on deep reinforcement learning by Xin SU, Leilei MENG, Yiqing ZHOU, Wu CELIMUGE

    Published 2022-10-01
    “…The strong heterogeneity among the network nodes of the maritime information system brings complex and high-dimensional constraints for optimizing task offloading of the maritime mobile edge computing.The complex and diverse maritime applications also lead to the overload processing of computing tasks in local areas of the maritime network.In order to optimize the task offloading and resource management of maritime network, as well as meet the maritime application service requirements of low-latency and high-reliability, a hierarchical classification method of maritime nodes based on multi-layers attributes and a novel offloading method for maritime mobile edge computing based on deep reinforcement learning were proposed.Compared with conventional methods, simulation results show that the proposed method can effectively reduce the computing task offloading delay of the marine information system, and maintain the robustness of the maritime network with large-scale task flows.…”

    High resistance botnet based on smart contract by Hao ZHAO, Hui SHU, Fei KANG, Ying XING

    Published 2021-08-01
    “…The development and application of blockchain technology makes it possible to build a more robust and flexible botnet command and control channel.In order to better study this type of potential new botnet threats, a highly confrontational botnet model based on blockchain smart contracts-SCBot was proposed.The SCBot model adopts a hierarchical hybrid topology structure, builds a command transmission channel based on smart contracts at the zombie subnet layer, and establishes a credibility evaluation mechanism to determine the authenticity of nodes, and enhances the confrontation of the network from the two major levels of traffic and terminals.The construction of small botnet clusters were simulated, comparative experiments on SCBot's command transmission efficiency and robustness were conducted, and its feasibility in the real environment from the perspective of economic costs was analyzed.Finally, a brief analysis and discussion of the defense strategy of this type of botnet were given.…”
