Mathematical Modeling and Analysis of Drill String Longitudinal Vibration with Lateral Inertia Effect by Jialin Tian, Chunming Wu, Lin Yang, Zhi Yang, Gang Liu, Changfu Yuan

“…According to the Laplace transform method and the relationships among parameters of the model, the solutions to complex impedance at the bottom of the drill string are obtained, and then the comparison results are analyzed, which is the lateral inertia effect on longitudinal vibration characteristics. The researches show that the smaller the length of the drill string, the greater the cross-sectional area of the drill string, the greater the damping coefficient of bottom hole on the bottom of the drill string, and the more evident the effect on the dynamic stiffness of the drill string with lateral inertia effect. …”

Energy-efficient strategy for data migration and merging in Storm by Yonglin PU, Jiong YU, Liang LU, Ziyang LI, Chen BIAN, Bin LIAO

“…Storm is suffering the problems of high energy consumption but low efficiency.Aiming at this problem,the resource constraint model,the optimal principle of data reorganization in executors and node voltage reduction principle were proposed based on the analysis of the architecture and topology of Storm,and further the energy-efficient strategy for data migration and merging was put forward in Storm(DMM-Storm),which was composed of resource constraint algorithm,data migration and merging algorithm as well as node voltage reduction algorithm.The resource constraint algorithm estimates whether work nodes are appropriate for data migration according to the resource constraint model.The data migration and merging algorithm designs an optimal method to migrate data according to the the optimal principle of data reorganization in executors.The node voltage reduction algorithm reduces voltage of work nodes according to node voltage reduction principle.The experimental results show that the DMM-Storm can reduce energy consumption efficiently without affecting the performance of cluster compared with the existing researches.…”

Analysis of the Load Sharing Characteristic of Compound Planetary Gear Set Under the Common Impact of Internal and External Excitation by Chao Yang, Haibo Zhang, Huijuan Zhu, Liping Feng

“…Current researches on load sharing characteristic concentrate on fluctuation of load sharing under the condition of single factor changing， which results in a poor comprehension on the load sharing behavior under the condition of multi-factors changing together，that’s to say， it’s difficult to find the most essential excitation among multi-factors affecting load sharing behavior，to improve the load sharing characteristic efficiently. …”
