| 1 | Game-theoretical Model for Dynamic Defense Resource Allocation in Cyber-physical Power Systems Under Distributed Denial of Service Attacks显示文摘Electric power grids are evolving into complex cyber-physical power systems(CPPSs)that integrate advanced information and communication technologies(ICTs)but face increasing cyberspace threats and attacks.This study considers CPPS cyberspace security under distributed denial of service(DDoS)attacks and proposes a nonzero-sum game-theoretical model with incomplete information for appropriate allocation of defense resources based on the availability of limited resources.Task time delay is applied to quantify the expected utility as CPPSs have high time requirements and incur massive damage DDoS attacks.Different resource allocation strategies are adopted by attackers and defenders under the three cases of attack-free,failed attack,and successful attack,which lead to a corresponding consumption of resources.A multidimensional node value analysis is designed to introduce physical and cybersecurity indices.Simulation experiments and numerical results demonstrate the effectiveness of the proposed model for the appropriate allocation of defense resources in CPPSs under limited resource availability. | Bingjing Yan Pengchao Yao Tao Yang Boyang Zhou Qiang Yang | 2024 | Journal of Modern Power Systems and Clean Energy2024，12，1： | 0 |
| 2 | VLSI Design for High-Precision Three-Dimensional Depth Perception Chip显示文摘This paper presents a Very large scale integration(VLSI)design method for Three-dimensional(3D)depth perception chip based on infrared coding structure light.The primary sub-modules on the chip contain the speckle pattern preprocessing module,blockmatching disparity estimation,depth mapping and postprocessing.The chip employs pipelining technology,and after Application specific integrated circuit(ASIC)verification,it proves that our chip has more advantages in performance of depth precision(12bits,1mm@1m),image resolution(1280×960),time delay(less than 17ms),range limit(0.4∼6m).It also can generate more stable and smooth depth map in real-time,which can be used in 3D recognition,motion capture or scene perception. | GE Chenyang YAO Huimin ZHOU Yanhui DENG Pengchao | 2021 | Chinese Journal of Electronics2021，30，3： | 0 |
| 3 | 锂氧电池中基于自支撑Ag/δ-MnO_(2)纳米花正极的可逆LiOH化学显示文摘因放电产物对有机电解液具有高攻击性,使得锂-氧电池能量效率低和循环稳定性差的问题一直限制着其实际应用.与典型放电产物过氧化锂相比,氢氧化锂(LiOH)具有更好的化学和电化学稳定性.本文通过在碳纸上原位生长嵌有纳米银的花状二氧化锰作为锂-氧电池的正极(Ag/δ-MnO_(2)@CP),并证明了它能催化LiOH的可逆生成和分解.原位拉曼测试和理论计算表明Ag/δ-MnO_(2)催化放电中间体LiO2*与水分子解离的H+反应最终生成LiOH.以Ag/δ-MnO_(2)@CP为正极的锂-氧电池在潮湿氧气环境下表现出更高的比容量和放电平台.在电流密度为200 mA g^(−1)时,锂-氧电池的过电位仅为0.5 V,在500 mA h g^(−1)的限制比容量下可循环867圈.该工作为研究固相催化剂在锂-氧电池中的作用提供了新的思路,并将促进基于LiOH放电产物的锂-氧电池的实际应用. | Linna Dai Qing Sun Yuqing Yao Huanhuan Guo Xiangkun Nie Jianwei Li Pengchao Si Jingyu Lu Deping Li Lijie Ci | 2022 | Science China Materials2022，65，6： | 0 |
