Self-organized CAC mechanism adopting for self-similarity service in wireless network by Lei FENG, Wen-jing LI, Xue-song QIU

“…To improve the access capacity in wireless network with the QoS ensuring,the service similarity in the wireless network was researched,and the service bandwidth was calal with similarity and QoS parameters.Then an SS-CAC (self-organized based on network similarity call admission control) mechanism based on the service bandwidth optimization was introduced to lower the system bandwidth utilization and service rejection probability.And the novel mechanism was achieved and simulated.Compared with traditional CAC,the results of simulation show the performance of SS-CAC mechanism can not only ensure the quality of the voice service but also reduce the bandwidth utilization of the data service by 2.69%.In addition,it can also reduce the call rejection ratio and call drop ratio by 0.95% and 2.81% respectively in the case of high cell load.…”

Design of the Gear Reducer Mechanism with Double Motor Redundancy Drive of the Refueling Switch by Maolin Tan, Lingling Zhao, Jing Wei

“…The design and analysis of the refueling switch gear reducer mechanism are carried out. Within the design conditions and design requirements comprehensively considered, the modeling,statics analysis and acceleration impact dynamic load simulation analysis are carried out.The results show that the designed gear reducer meets the design requirements and design conditions,and the maximum strain,maximum deformation and maximum instantaneous impact stress are less than the allowable value.Besides, the accuracy of the finite element model is verified by the real object, and all functions could be realized through the test without interference,which fully meet the design requirements.…”
