Service migration optimization method for resource competition in mobile edge computing scenarios by WANG Haiyan, ZHANG Lin, LUO Jian

“…To tackle the problem of resource competition among service migrations caused by limited edge server resources in mobile edge computing (MEC) scenarios, a service migration optimization method for resource competition based on Lyapunov and game theory (OMRC-LG) was proposed. Considering the system's limited migration costs and the difficulty of predicting trajectories when the number of users was large, the service migration was modeled as an optimization problem with migration cost constraints and used the Lyapunov technique to transform it into an online problem without user trajectory prediction. …”

State-of-the-art and trend of emergency rescue communication technologies for coal mine by Qingsong HU, Wei YANG, Enjie DING, Shiyin LI, Binghao LI

“…For the disaster area probing and emergency rescue in a mine,it is of great importance to employ the emergency communication system to communicate with each other,determine the places of trapped miners,and sense current status of disaster area.The hybrid emergency communication architecture model for coal mines was extracted,which was composed of one backbone,multiple branches,several special lines,and some wireless networks as assistance.Four types of emergency communication systems of coal mine were reviewed,namely through-the-air,through-the-wire,through-the-earth and mixed medium type.The key technologies and challenges of these four emergency communication types were analyzed.The research trend was discussed and a new emergency communication mode based on the reconstruction of mine Internet of things was proposed.The main enabling technologies of this new emergency communication mode were analyzed,namely post-disaster reconstruction of mine Internet of things,shifting nodes re-localization after mine disaster,status sensing method of mine disaster area,and data transmission method for post-disaster reconstruction network.…”

Structure Design of the Force Testing Central Support of a Transonic and Supersonic Wind Tunnel by Dong Bin, Zhou Xiaogang, Wang Tao, Fan Changhai

“…The force testing central support is an important part of the model supporting system in a transonic & supersonic wind tunnel,the performance of which is qualified or not would directly affect the control of model attitude angel during wind tunnel tests.First,aiming at the problem that the roll angle backlash is oversized during force tests,the self-locking dual lead cylindrical worm transmission is applied to the force testing central support to solve this problem.Meanwhile,considering that the aerodynamic load is heavy,the slider and the bulging joining sleeve are both used to share the load.Then,the static structural strength of the worm transmission are checked,and at the same time,the finite element analysis is carried out to study the stress and deformation both in the sustaining body and the chief axis.Finally,the calibration model tests for the new force testing central support in comparison with the former one are conducted.Results indicate that the structural design is reasonable,the data presented a good correlation,and the design of the new force testing support is successful for wind tunnel tests.…”

Performance analysis of orthogonal signals with TASP/MRC diversity by Guangqiu LI, Siting WANG

“…In order to solve the design problem of predictive transmit antenna selection (TASP) / receive antenna maximum ratio combining (MRC) wireless communication system with the minimum mean square error (MMSE) channel prediction,exact and approximate closed-forms for the average symbol error rate (ASER) of M-ary ortho-gonal and biorthogonal signals with coherent detection and TASP/MRC over Rayleigh block fading channel were de-rived by using parabolic cylinder function,the approximate expression of Gaussian Q-function and moment generat-ing function (MGF) based analysis approach respectively.Numerical and simulation results show that the theoretical analysis of the ASERs of orthogonal and biorthogonal signals is exact and the approximate closed-form for the ASER of orthogonal signals is accurate.The above exact or/and approximate closed-forms of ASER of orthogonal and biortho-gonal signals with coherent detection and TASP/MRC can be used to determine the number of antennas of transmitter and receiver and the parameters of predictor quickly,instead of the time-consuming and inefficient computer simulation.…”
