    Research on language recognition algorithm based on improved CFCC feature extraction by Hua LONG, Zhangheng HUANG, Yubin SHAO, Qingzhi DU, Shumeng SU

    Published 2022-12-01
    “…Aiming at the problem of low language recognition rate under low signal-to-noise ratio, a language recognition method based on fractional wavelet transform was proposed.Firstly, the adaptive filtering algorithm was used to filter the noise of the noisy signal, so as to reduce the influence of noise on the feature extraction and improve the processing ability of the system for non-stationary signals.Secondly, the motion of the signal on the basilar membrane of the cochlea was simulated, and then the signal was compressed by a nonlinear power function.Finally, the improved CFCC were extracted by simulating the human hearing process.Experiments show that compared with the traditional CFCC, the language recognition rate is significantly improved, and the language recognition rate is increased by 11.1% on average under the 0 dB signal-to-noise ratio, which verifies the effectiveness and robustness of the proposed algorithm.…”

    Fast algorithm to search for the minimum number of active S-boxes of block cipher by Zhengbin LIU, Yongqiang LI, Chaoxi ZHU

    Published 2023-01-01
    “…To solve the problem of fast calculation of the minimum number of active S-boxes in cryptographic design, the difference and mask propagation of the diffusion layer were investigated, and a method was proposed to compute the difference (resp.mask) pattern distribution table of MDS (maximum distance separable) matrices and binary matrices.A lower bound on the computation complexity of the proposed method was also given.Based on the difference (resp.mask) pattern distribution table of diffusion matrix, a fast algorithm to search for the minimum number of active S-boxes of block cipher was proposed.The proposed algorithm is applied to some SPN (substitution permutation network) block ciphers, and finds the minimum number of active S-boxes for the full round of LED, SKINNY, CRAFT and FIDES.…”

    Control of the Elastic Torsion System based on Dynamic Matrix Control Algorithm by Jiang Hao, Yu Songzhou

    Published 2015-01-01
    “…The multi-mass elastic torsional system has the feature of large speed fluctuation and long vibration time.The system state space model is built based on the system analysis,and the parameters of this model are estimated by using Simulink Parameter Estimation Toolbox.The system speed is controlled by using dynamic matrix control(DMC)algorithm.The DMC controller is converted into embedded C code which is executable for PLC by using Simulink Coder toolbox in Matlab.After being compiled by Automation Studio,it will be downloaded to X20 PLC to control the real system.Both the simulation and practical system test shows that the model is accurate and DMC algorithm is better than cascade PID algorithm in dynamic performance.…”

    Distributed data trading algorithm based on multi-objective utility optimization by Xiaohong HUANG, Yong ZHANG, Desheng SHAN, Yekui QIAN, Lu HAN, Dandan LI, Qun CONG

    Published 2021-02-01
    “…The traditional centralized data trading models are not well applicable to the current intelligent era where everything is interconnected and real-time data is generated, and in order to maximize the use of collected data, it is essential to design an effective data trading framework.Therefore, a distributed data trading framework based on consortium blockchain was proposed, which realized P2P data trading without relying on a third party.Aiming at the problem that existing data trading models only consider the factors of the data itself and ignore the factors related to user tasks, a bi-level multi-objective optimization model was constructed based on multi-dimensional factors, such as data quality, data attributes, attribute relevance and consumer competition, to optimize the utilities of data provider (DP) and data consumer (DC).To solve the above model, an improved multi-objective genetic algorithm-collaborative NSGAII was proposed, calculated by the cooperation of DP, DC and data aggregator (AG).The simulation results show that the collaborative NSGAII achieves better performance in terms of the utilities of DP and DC, thus realizing more effective data trading.…”
