    Study on separated double pulse position modulation and its performance by XU Zhi-yong1, SHEN Lian-feng1, WANG Jing-yuan2, LIU Ye2

    Published 2009-01-01
    “…Separated double pulse position modulation(SDPPM) in wireless ultraviolet communication was presented.The structure of the SDPPM was described in detail.Requirements of the power and the bandwidth for SDPPM were analyzed and the BER was derived.Then these performances were compared with modulation of equal slots,such as OOK,PPM and MPPM.The results show that the SDPPM achieves better compromise between power requirement and bandwidth requirement,and the SDPPM has better performance in anti-multipath dispersion in ultraviolet communication because of its symbol structure.…”

    Electrochemical Performance Measurements of PBI-Based High-Temperature PEMFCs by Javier Parrondo, Chitturi Venkateswara Rao, Sundara L. Ghatty, B. Rambabu

    Published 2011-01-01
    “…Similarly, the mass transfer resistance or Warburg impedance increased 2.5 times, reaching values of 6 Ohm-cm2. 5 wt.% PBI-based MEA showed the best performance. The electrochemical impedance measurements were in good agreement with the fuel cell polarization curves obtained, and the optimum performance was obtained when overall resistance was minimal.…”

    Wear Performance of Bionic Dimpled-Shape Pistons of Mud Pump by Xuejing Cheng, Tianyu Gao, Shaofeng Ru, Qian Cong

    Published 2017-01-01
    “…By imitating the body surface morphology of the dung beetle, this paper proposed a new type (BW-160) of mud pump piston that had a dimpled shape in the regular layout on the piston leather cup surface and carried out a performance test on the self-built test rig. Firstly, the influence of different dimple diameters on the service life of the piston was analyzed. …”
