Evaluation and Optimization of Multi-service Complex NetworkCoverage Based on NB-IoT

NB-IoT(Narrow Band Internet of Things)is China Mobiles main technology for future IoT development.Good network coverage quality and low power consumption design are its competitive advantages in the future.However,there are bottlenecks in NB-IoT,such as serious overlapping coverage,large local coverage,and insufficient indoor coverage.In view of the above problems,this paper proposed an evaluation and optimization method based on NB-IoT multi-service complex network coverage.According to the feat...

IP Network Congestion Link Packet Loss Rate Inference AlgorithmBased on Link Intrinsic Correlation

In order to solve the problem of complex network topology and inaccurate analysis of link loss rate in the network link loss rate inference algorithm,previous studies used a hypothesis that sub-link or a link in a path with a high pass rate is a non-loss link,or the most shared link is a packet loss link,but these assumptions lack valid reasoning and proof.In order to solve this problem,this paper proposed IP network congestion link packet loss rate inference algorithm based on link intrinsic cor...

Mechanical Response Analysis of Shear-CompressionSpecimens Under Dynamic Loading

In this paper,the 3D numerical simulation of compression process of Ti 6Al 4V titanium alloy shear-compression specimen(SCS)was carried out on ABAQUS software,and the mechanical response of compression-shear specimen under static and dynamic loading was studied.The influence of the geometric parameters(length to diameter ratio,root radius and thickness)of the SCS specimen on the analysis of the experimental results of the separated Hopkinson pressure bar(SHPB)was analyzed,and the feasibility of o...

Effect of Different Level of Strength Loss for Quadriceps and Hamstringson Tibiofemoral Contact Forc

On the basis of the subject-specific musculoskeletal multi-body dynamics model after total knee replacement established by two open-source software nmsBuilder and OpenSim,we studied the effect of different level of strength loss for quadriceps and hamstrings on tibiofemoral contact forces under normal gait pattern.This study adjusted the maximum isometric force of the target muscle to achieve the purpose of muscle strength loss,then inverse kinematics,static optimization and joint reaction force ...
