Opportunistic spectrum access method for cognitive radio sensor network of typical deployment strategies by Wen-xiang LI, Ya-jie MA, Peng KE

“…Explored the opportunistic spectrum access method for cognitive radio sensor networks with regular topology patterns and coverage patterns.The method includes an economic spectrum-and-timeslot-allocation scheme,a sensing-results-reporting scheme and a cooperative spectrum-sensing scheme.A model was proposed for analyzing the blocking and dropping probability for secondary users,the effective reception bandwidth and transmission delay.Numerical analysis shows that Triangle yields the optimal cooperative sensing performance,and square yields the optimal reception bandwidth.In case of complete coverage,Square and triangle lead to less transmission delay,and in case of multiple coverage,square leads to the least transmission delay.The false alarm probability of single node has little impact on transmission delay,and Primary User’s activity may affect delay noticeably.On the other hand,larger ratio of transmission timeslot to sensing timeslot helps to decrease delay.…”

Study on Stability Control Measures for Large Deformation of Carbonaceous Slate at Diversion Tunnel of Guzeng Hydropower Station by GUO Yi, CHEN Yang, JIANG Yufei, YIN Ziwen, HU Tianming, ZHANG Jixun

“…Carbonaceous slate has the characteristics of weak rock mass and softening by water.When hydraulic tunnel construction is carried out in this type of rock mass with high crustal stress,large deformation of surrounding rock will occur in most cases.The control of large deformation is the key and difficult point to ensure no delay on construction period and long-term stable operation of the project.Combined with the condition of large deformation of carbonaceous slate at diversion tunnel of the Guzeng Hydropower Station,based on the analysis of large deformation mechanism of carbonaceous slate,and according to the geological phenomena and possible hydrogeological problems revealed by the site construction,this paper analyzes the support system of the tunnel section by combining numerical analysis and on-site monitoring,and puts forward reasonable support suggestions for reference by similar projects.…”

TRANSMISSION ACCURACY OF SYNCHRONOUS BELT BASED ON RECURDYN by GUO JianHua, MENG QingXin, YU Xin, HU QingMing

“…Using the mechanism of the tooth climbing of the belt,the mathematical model of the transmission error is established,reveals the transmission error of the synchronous belt is a function of the pulley pitch angle.Establish the virtual prototype dynamic transmission simulation model of synchronous belt based on Recur Dyn,through collect data and numerical analysis that mesh point with climbing tooth trace-Archimedes spiral,simulation results are consistent with the experimental results,to verify the accuracy of the simulation analysis.And compare the transmission accuracy of the new profile and L type trapezoidal tooth synchronous belt.The results showed that the transmission error of the new profile synchronous belt（Δθ =0.932mrad） less than L type trapezoidal toothed（Δθ = 1.615mrad）,shows that the capacity anti climbing tooth of the new profile synchronous belt is stronger than L type trapezoidal tooth,the tooth design of new profile synchronous belt is more reasonable.…”
