    Optimization and Analysis of Double-circular-arc Harmonic Gear based on Genetic Algorithm by Zhonglong Luo, Xiaochuan Peng

    Published 2021-07-01
    “…Through analyze the single parameter sensitivity of the optimized parameters, it is found that the objective function has a low sensitivity to the arc radius of convex and concave tooth, and the tooth thickness ratio. Therefore, to control the manufacturing accuracy of the flexspline and increase the "dual conjugate" interval, one of the useful way is that relax the size error of low sensitivity parameters and control the size error of high sensitivity parameters appropriately.…”

    Mode selection and resource optimization for UAV-assisted cellular networks by Daquan FENG, Canjian ZHENG, Xiangqi KONG

    Published 2024-03-01
    “…The resource allocation and optimization scheme was studied in a coexistence scenario of unmanned aerial vehicle (UAV) and cellular communication network.To improve spectrum efficiency of the system, UAV users could reuse the cellular spectrum resources to access the network through full duplex or half duplex device-to-device technique.Additionally, a joint access control, mode selection, power control and resource allocation optimization problem was formulated to maximize the overall throughput of the network while ensuring quality of service requirements for both UAV users and ground cellular users.Specifically, the phase 1 method in the convex optimization was adopted for access control and feasibility check, and then the convex and concave procedure (CCCP) iterative algorithm was used to solve the power control problem for feasible UAV user pairs.By using this local optimum value, the original optimization problem can be simplified into a weighted maximization problem.Finally, the Kuhn-Munkres (KM) algorithm was used to match the optimal channel resources and obtain the global optimal throughput value of the system.Numerical results show that the proposed scheme can significantly improve the performance of system.…”
