    Determination of an Optimal Oil Jet Nozzle Layout for Helical Gear Lubrication: Mathematical Modeling, Numerical Simulation, and Experimental Validation by Yu Dai, Jifu Jia, Bin Ouyang, Jianeng Bian

    Published 2020-01-01
    “…Finally, experiments on the temperature characteristics measured by an infrared thermal imager of helical gears with different nozzle parameters were carried out in a gear test rig. The simulation results of transient temperature field are in good agreement with those obtained by experiments, and it indicates that the thermal-fluid coupling analysis method is correct and feasible to predict the temperature field of the helical gear pair under oil injection jet lubrication.…”

    Encrypted traffic classification based on packet length distribution of sampling sequence by Chang-xi GAO, Ya-biao WU, Cong WANG

    Published 2015-09-01
    “…A hypothesis testing-based statistical decision model (HTSDM) for application identification of encrypted traf-fic was presented.HTSDM was based on packet length distribution of deterministic sampling sequence at flow level,which was characterized by packet positions,packet directions,packet sizes,packet arrival continuity and packet arrival order.HTSDM boosted deep packet inspection (DPI) by introducing constraints of packet position and direction as well as inter-flow correlation action.A hybrid method of encrypted traffic classification combining DPI and dynamic flow in-spection (DFI) was proposed based on HTSDM.Experiment results show that this method can effectively identify the unique statistical traffic behavior of encrypted application in flow coordinate space,and achieve high precision,recall and overall accuracy while keeping low false positive rate (FPR) and overall FPR.…”
