Cross-network access control mechanism for complex network environment by Fenghua LI, Tianzhu CHEN, Zhen WANG, Linjie ZHANG, Guozhen SHI, Yunchuan GUO

“…,integration of multi-network and information flow in cross-network.These characteristics bring access control for complex network environment the new requirement of coarse-grained control,sticky policies and inconsistent operation semantics.To satisfy these requirements,cross-network access control mechanism in complex network environments (CACCN) was designed by mapping the cyberspace-oriented access control.First of all,the process of mapping was illustrated using the example of space-ground integrated networks.Next,a management model was proposed to manage the control elements in CACCN and a series of management functions were designed by using Z-notation.The analysis on practical example demonstrates that the mechanism can satisfy a series of access control requirements.…”

Zeroing neural network for time-varying convex quadratic programming with linear noise by Jianfeng LI, Zheyu LIU, Yang RONG, Zhan LI, Bolin LIAO, Linxi QU, Zhijie LIU, Kunhuang LIN

“…Aiming at the problem that linear time-varying noise may have a negative impact on the existing zeroing neural network model to solve TVQP problem, resulting in slow convergence and low accuracy of the model, a double integral enhancement zeroing neural network was proposed.To solve the problem of linear time-varying interference of the noise, the double integral was introduced based on the original ZNN design formula, and a activation function was designed to eliminate the effects of linear time-varying noise.Theoretical analysis proved that the DIEZNN model had convergence and good noise suppression ability.The experimental results show that compared with the traditional gradient neural network and other variable ZNN models, the proposed DIEZNN model has faster convergence and higher accuracy, and can effectively solve the linear time-varying noise.…”

Speech enhancement method based on multi-domain fusion and neural architecture search by Rui ZHANG, Pengyun ZHANG, Chaoli SUN

“…In order to further improve the self-learning and noise reduction ability of speech enhancement model, a speech enhancement method based on multi-domain fusion and neural architecture search was proposed.The multi-spatial domain mapping and fusion mechanism of speech signals were designed to realize the mining of real complex number correlation.Based on the characteristics of convolution pooling of the model, a complex neural architecture search mechanism was proposed, and the speech enhancement model was constructed efficiently and automatically through the designed search space, search strategy and evaluation strategy.In the comparison and generalization experiment between the optimal speech enhancement model and the baseline model, the two indexes of PESQ and STOI increase by 5.6% compared with the optimal baseline model, and the number of model parameters is the lowest.…”

Research and Motion Analysis of Cutting Blade Mechanism of Copper Foil Shearing Machine by Ying Yueming

“…It is always a problem to improve the quality of copper foil shearing in PCB production.In order to research and develop copper foil shearing machine which has international competitiveness,taking the shearing mechanism of copper foil shearing machine designed by Rosenthal company in US as study object,the mechanism principle of shearing mechanism is descriped and the degree of freedom of mechanism is calculated.The motion analysis of shearing mechanism is carried out based on the methods of spatial mechanism kinematics and numerical calculation.Then,the analytic parameter formula of shearing mechanism cut point is deduced.The motion feature of shearing mechanism based on high speed and high cutting quality is proposed through the numerical experimentation and simulation experiment of shearing machine with 1500 copper foil breadth.The movement curve and controllable parameter which affects the performance of mechanism are obtained.The research contents can be taken as reference for the optimization of cutting blade mechanism design parameters.…”

Blockchain and credibility function based chain storage method of electronic encrypted information by Ting ZHOU

“…To optimize the proportion of encrypted information storage space in the blockchain and improve the speed of online storage, a design method for electronic encrypted information online storage based on blockchain and credibility function was proposed.An information encryption classification model based on blockchain and credibility function was established, and a traceability voucher judgment function was obtained.Proxy re-encryption was performed on electronic information.The storage capacity of the cluster was calculated, and encrypted ciphertext was used to directly match the access structure tree.Subject credibility and object credibility were distinguished, electronic encrypted information was classified based on the credibility function, and an electronic encrypted information uplink storage method was designed.The experimental results show that after applying the proposed method, when the number of files is between 1 000 and 10 000, the data storage speed is the fastest, and the storage space proportion and storage speed are greatly optimized.…”
