    Fault Diagnosis of Variable Speed Gear based on ATF and ASAD by Xiangmin Chen, Meng Duan, Qi Li, Guoqiang Shu, Kang Zhang, Luping Li

    Published 2021-10-01
    “…By combining ASAD and ATF,the signal after noise reduction is analyzed by order spectrum,and the local fault of gear can be diagnosed by modulation side frequency band in order spectrum. The simulation data and the data analysis of the variable speed gearbox test bench show that the proposed method has a good signal analysis adaptability for the gear vibration signals under the variable speed condition,and can not only filter out noise interference well,improve the noise suppression effect in the pass band,but also effectively highlight the gear fault characteristics under the variable speed condition.…”

    Interference elimination based spectrum allocation algorithm for cognitive radio by Wen-feng DU, Ya-tao LIU, Zhong MING, Yin-xue SUI

    Published 2012-05-01
    “…With the spectrum allocation process in cognitive radio network,an interference elimination based spectrum allocation algorithm was proposed to improve the utilization of spectrum by allocating available spectrum to all cognitive users which can simultaneously access the same spectrum without interference.Meanwhile,this algorithm would allocate spectrum to cognitive user,which had not been assigned in previous allocation process,with reference to the amount of available spectrums in the initial stage to optimize t fairness of spectrum allocating process.Extensive simulation results show the proposed algorithm can achieve better throughput when the amount of available spectrum is far less that of cognitive user.…”

    Published 2021-03-01
    “…The previous assured deletion schemes ignored that the privacy is threated by the relevance between data and user identity, exposing user behavior to the cloud service provider or attackers.Aiming at the above problems, an assured deletion approach based on blockchain was proposed.The improved linkable ring signature scheme was adopted to make user achieve anonymous assured deletion by setting specific link symbol in the signature.Moreover, the blockchain technology was leveraged to guarantee the nonrepudiation of assured deletion.Theoretical analysis and experimental results show that the proposed approach can meet the assured deletion requirements of user data in cloud storage, and its anonymity can effectively prevent attackers from tracking and analyzing user behavior.…”
