Research on low complexity decoding for SCMA based on serial strategies of variable node by Mingming JI, Jianhong ZHENG

“…Sparse code multiple access technology,as a competitive non orthogonal multiple access scheme for the fifth generation wireless communication network,has a broad application prospect.However,current SCMA uplink use the flooding scheme of message passing algorithm for decoding,both the detection complexity and convergence properties are not ideal.A serial message passing algorithm which changed the information updating strategy was proposed,which performed message processing and deliveried according to the order of the variable nodes.Each of variable node simultaneously performed the reception of the verification message and the transmission of the variable message.The theoretical and simulation results show that the proposed algorithm not only maintains good performance,but also has low decoding complexity.…”

Finite Element Analysis of Top Cover Bolts of Hydraulic Turbine Based on ANSYS Workbench by ZHAO Junjie, YU Bo, OU Qian, SU Ting, WANG Yi

“…The working conditions of the hydraulic turbine are frequently changed.If the connecting bolts between the top cover and the stay ring are subjected to a load,and they are loose or broken,the serious consequences such as the plant flooding and even the machine destruction and death may occur.This paper establishes the calculation model of the connecting bolts between the top cover and the stay ring of hydraulic turbine by the ANSYS Workbench software,and calculates and analyzes the maximum stress of connecting bolts and the position of the dangerous section under different load rejection conditions by the finite element analysis method.The calculation results show that:when the load rejection is 82.5 MW,the stress on the connecting bolts is the largest.Therefore,the ultrasonic online monitoring and early warning system shall be applied to monitor the most dangerous bolts in real time to prevent accidents.…”

Straw return combined with water-saving irrigation increases microbial necromass accumulation by accelerating microbial growth-turnover in Mollisols of paddy fields by Peng Chen, Junzeng Xu, Kechun Wang, Zhongxue Zhang, Zhaoqiang Zhou, Yawei Li, Tiecheng Li, Tangzhe Nie, Qi Wei, Linxian Liao

“…., microbial growth, respiration, carbon use efficiency (CUE) and biomass turnover] of Mollisols responds to different management protocols, and to evaluate their carbon sequestration potential, we examined microbial anabolism, catabolism and necromass accumulation in Mollisols paddy fields under four treatments: (i) controlled irrigation + rice (Oryza sativa L.) straw removal (CI), (ii) flooded irrigation + rice straw removal (FI), (iii) controlled irrigation + rice straw return (CI-SR), and (iv) flooded irrigation + rice straw return (FI-SR). …”
