Fusion spectrum sensing algorithm based on eigenvalues
Published 2019-11-01“…Aiming at the problem of inefficient use of spectrum resources,a fusion spectrum sensing algorithm based on eigenvalues was proposed to effectively achieve dynamic spectrum sharing.The test statistics were constructed by employing the maximum eigenvalue,the trace and the geometric mean of all eigenvalues of the sample covariance matrix.The detection probability and false alarm probability of the proposed method were analyzed using the random matrix theory,and the analytical representation of the theoretical threshold was obtained.In addition,the parameter selection of the proposed algorithm was analyzed theoretically.Simulation results show that the proposed algorithm has better detection ability than the existing eigenvalue detection algorithm.…”

Research on cryptographic properties of a new S-box based on cellular automaton
Published 2019-05-01“…A new S-box based on cellular automata was found by experiments.The permutation properties of the S-box were analyzed,which proved that the S-box was a permutation only when the size of lattice was 5.Then the relation between the nontrivial difference transition probability of the S-box and the rank of the difference matrix was proved by constructing the difference matrix.And it was proved that the cyclic shift of input differential would not change the corresponding nontrivial differential transition probability,and obtained the sufficient and necessary conditions about the maximum and minimum nontrivial differential transition probabilities when the size of lattice was 5.Then the problem of the difference distribution of the S-box in this situation is completely solved.…”

Risk Analysis of Sequential Dam Break of Cascade Reservoirs and Simulation of Flood Routing
Published 2021-01-01“…To study the risk of sequential dam break of cascade reservoirs,and to simulate and analyze the flood routing process,by constructing a Bayesian network model for the sequential dam break of double reservoirs under the action of extra standard floods and piping,and combining the dam break and flood routing simulation of Breach dam-break numerical model and two-dimensional HEC-RAS hydrodynamic model,this paper calculates the probability of dam break,evaluates the risk of sequential dam break,and simulates the flood routing process,taking Hanconggou Reservoir and Dingguoshan Reservoir as examples.The calculation results show that:Through Bayesian-based backward inference of the known dam break of Dingguoshan Reservoir,the probability of “Hancongou Reservoir dam break” increased from 3% to 87%;while through Bayesian-based backward inference of the known dam break of Hancongou Reservoir,the probability of “Hancongou Reservoir piping” increased from 16% to 87%.Under extra standard flood and piping conditions,due to the sequential dam break of the two reservoirs,the time for the flood to reach the section CS1—CS6 is 0.8~3.0 h;under the flood conditions that occurred once in 1 000 years,the Hancongou Reservoir was opened for flood discharge but the dam was not broken.Only the Dingguoshan Reservoir was over-topped with dam break,and the flood reached the section CS1—CS6 in 21.5~26.5 h.This study can provide scientific reference for reducing dam break risk,and making emergency plan and disaster prevention & mitigation plan.…”
