Combined Homing Guidance Law of Torpedo Based on Fuzzy Control by Baoming MU, Jianqing CHENG, Feng PAN

“…In the process of torpedo homing guidance, it is difficult for a single guidance method to adapt to different guidance phases and ensure the torpedo guidance effect effectively. For this reason, this paper designs a fuzzy combined guidance law based on the principle of fuzzy control by combining three different typical guidance methods, namely, fixed lead angle guidance method, proportional guidance method, and variable structure guidance method. …”

La politique de l’eau en Afrique du Sud : le difficile équilibre entre développement durable et valorisation optimale de la ressource by David Blanchon

“…This paper shows that the implementation of the environmental Reserve and the water demand management policy have paradoxically accelerated the competition between regions for the access to water resources, and only temporarily stopped the building of huge dams and inter-basin transfers. One major reason is the controversial status of the environment in South Africa, deeply disturbed by the apartheid regime, and still politically and socially problematic.…”

STUDY ON THE NUMERICAL SIMULATION IN THE PROCESS OF ROLLING WAVE AND ECCENTRIC CIRCULAR WITH RADIATING CORRUGATED RIBBON by ZHAO XianFeng, SHI HongYan, CHEN XiaoYu, ZHOU ShunJun

“…In order to analyze the change law of stress of aluminum chaff in the process of rolling waves,and the reasons of the eccentric circular to get the accurate wave of radiating corrugated ribbon,the model of bilinear isotropic harden was established to simulate the process of rolling wave in the Ansys Workbench.The result of rolling wave Aluminum chaff was verified on the machine of rolling wave.The results show that the curve of stress is the form of wave which correspond to the wave of aluminum chaff; The residual stress of aluminum chaff reduce along the arc of peak,while the reduce is asymmetric distribution on both sides,which is the reason of the eccentric circular; due to the meshing movement of tool,the plastic strain increased to the maximum in stages; the model of actual rolling waves match with the the theory modal,which verify the correctness of the analytical method.…”

International legal conventions as an instrument for preventing environmental risks by E. I. Mayorova

“…Nature continues to be considered as the basis of the economy, and participation in international agreements means restrictions on certain economic activities, therefore, a number of countries do not ratify international environmental conventions for economic reasons, neglecting environmental consequences. Another reason for the refusal of ratification is the desire to hide from the public information about the deterioration of the environment, which is a violation of the interests of civil society and a risk to human health.…”

Trusted auditing method of virtual machine based on improved expectation decision method by Junfeng TIAN, Yongchao ZHANG

“…Whether the cloud computing environment is credible is the key factor in the promotion and effective use of cloud computing.For this reason,the expected value decision method in risk decision-making was improved.The usage scenarios was redefined,the cost and benefit of audit scheme was digitized,and a virtual machine trusted auditing strategy based on improved expectation decision method was proposed.Several levels of security protection for the user virtual machine was provided,and the optimal audit scheme was selected autonomously according to the security protection level chosen by the user for the virtual machine.The virtual machine introspection (VMI) technology was used to obtain the virtual machine information that needs to be audited.The designed encryption mechanism was used to protect the security of users selected security protection level,so as to ensure the security of user virtual machine selection audit strategy.Finally,the simulation results show that the scheme has good performance and validity.…”

Power saving techniques for 5G RRC_Idle mode UE by Tuo YANG, Lijie HU, Fei WANG, Jianjun LIU, Nan HU, Nan LI, Zhenping HU

“…The power consumption of 5G UE is much serious than 4G UE due to larger bandwidth, massive MIMO, and higher data rate and has been one of the important reason affecting users’ experience of 5G network.3GPP has promoted the study and standardization of NR UE power saving techniques, which the R16 techniques is designed for RRC_connected mode and the started R17 techniques focus on RRC_idle mode.The power consumption of NR UE in RRC_idle was analyzed and compared with LTE UE.The power saving techniques to solve the power consumption in paging and tracking procedure were proposed and the power saving gain were also evaluated.The proposed techniques can reduce 5G UE power consumption and be applicable to future 5G commercial UE.…”
