Mobility aware edge service migration strategy by Dapeng WU, Ji LYU, Zhidu LI, Ruyan WANG

“…To address the problem of load imbalance among edge servers and quality of service degradation caused by dynamic changes of user locations in mobile edge computing networks,a mobility aware edge service migration algorithm was proposed.Firstly,the optimization problem was formulated as a mix integer nonlinear programming problem,with the goal of minimizing the perceived delay of user service request.Then,the delay optimization problem was decoupled into the edge service migration and edge node selection sub-problems based on the Lyapunov optimization approach.Thereafter,the fast edge decision algorithm was proposed to optimize the resource allocation and edge service migration under a given radio access strategy.Finally,the asynchronous optimal response algorithm was proposed to iterate out the optimal radio access strategy.Simulation results validate the proposed algorithm can reduce the perceived delay under the service migration cost constraint while comparing with other existing algorithms.…”

Nonthermal electron-photon steady states in open cavity quantum materials by R. Flores-Calderón, Md Mursalin Islam, Michele Pini, Francesco Piazza

“…Moreover, by defining an effective temperature from the on-shell distribution function, we find a nonmonotonic behavior as a function of cavity frequency, consistent with recent experimental findings. Finally, we show that, the nonthermal behavior leads to qualitative modifications of the materials properties, as the standard Sommerfeld expansion for observables is modified by a leading-order correction linearly proportional to the temperature difference between the two baths and to the frequency derivative of the electron damping.…”

“…In order to improve the accuracy and efficiency of the discovery of the antenna-feeder problem,an optimal direction angle solution based on Gaussian distribution was proposed to diagnose the antenna-feeder coverage problems of operators.First of all,the location direction information between each MR sampling point reported by the UE and the base station was calculated,and then the proportion of MR sampling points in each interval was calculated,Based on the Gaussian distribution feature,the angle range with the largest proportion of MR sampling points was the appropriate azimuth,which was based on the user hotspot distribution of the sector.Finally,the date of optimal azimuth was compared with the base station azimuth in the background antenna database to detect antenna feeder problems,such as cross feeder,improper antenna coverage direction and incorrect background antenna database,and so on.The field verification shows that,the cost,accuracy and efficiency of the antenna-feeder problems are obviously improved compared with the existing methods.…”

“…Aiming at the problem that the contact stiffness analysis method of curvic couplings can not consider the contact interface microscopic morphology,an analytical model of the contact interface stiffness was proposed.Through the stress analysis and stiffness transformation,the general model of curvic couplings contact interface stiffness was obtained,and the GW rough surface model was brought into it to obtain the specific curvic couplings contact interface stiffness formula based on the GW rough surface model.Finally,the analytical model results were compared with finite element results.The effect of surface topography on the contact stiffness of curvic couplings was obtained,and the relationship between the normal contact stiffness and the tangential contact stiffness with the preload and tangential force were obtained.The research shows that the analytical model matches well with the finite element results,which proves the rationality of the analytical model and provides a theoretical reference for the preload force and torque design of the rotors with curvic couplings.…”
