A Statistical Model of Inner Magnetospheric Electron Density: Van Allen Probes Observations by Jing‐Tian Lv, Xiao‐Xin Zhang, Fei He, Rui‐Lin Lin

“…Abstract Based on electron density observations between September 2012 and July 2019 from the Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) on board the Van Allen Probes (VAPs) spacecraft, this paper makes a statistical investigation on the distribution of inner magnetospheric electron density in the magnetic equatorial plane (MEP) under different Kp levels, and further develops a new model of inner magnetospheric electron density in the MEP with multi‐parameters (Kp, SYM‐H, Pdyn, F10.7). The statistical results show that the plasmaspheric electron density in the inner magnetosphere in the MEP has an obvious Magnetic Local Time (MLT) distribution characteristic. …”

SIMPLIFIED CALCULATION OF MESHING STRENGTH OF FACE GEAR PAIR (MT) by HE Fei, QIAN WeiXiang, FU XueZhong, PENG XianLong

“…The tooth thickness at the dangerous section of gear teeth was determined by the 30° tangent method, and the stress calculation coefficient table was given based on the expression of basic parameters of gear pair, finally, the analytical calculation formula of tooth root bending stress was deduced. Taking face gear pair with a certain design parameter as an example, the results obtained from the analytical calculation models were compared with those from the finite element simulation to verify the accuracy of models. …”

Research on correlation noise modeling of a generalized Gamma distribution in distributed coding by Jie-ping LIU, Qin-ling WANG, Yue-sheng HE, Gang WEI

“…Due to the inaccuracy of modeling the correlated noise (CN) with Laplacian distribution,the rate-distortion performance of DVC is relatively low.CN modeling via generalized Gamma (GGA)distribution was proposed for pix-el-domain DVC.Statistical features of the CN modeling were analyzed.It was found that Laplacian distribution peak was lower than actual CN distribution.GGA distribution was exploited to fit CN and the GGA distribution parameters were estimated online.The simulation results indicate that the proposed model can more accurately reflect the statistics fea-tures of CN,improve rate distortion performance,and reduce computation complexity.…”

Research on packet convergence sublayer classification algorithm for WiMAX system by ZHANG Qing-bo1, HE Jia-ming1, ZHU Yan3

“…The mapping relation between the higher-layer protocol data and connection was analyzed in WiMAX system.And a packet convergence sublayer classification algorithm based on non-collision hashing and address-blocking XOR look-up was proposed,thus realized the quick look-up and classification of higher-layer protocol data.The complexity and the increase renewal function of algorithm was analyzed quantitatively.The simulation results show that the classifi-cation algorithm satisfies QoS（quality of service） requests with the performances of delay and memory,moreover time-liness is also enhanced greatly.…”
