| 1 | Polynomial-rooting based fourth-order MUSIC for direction-of-arrival estimation of noncircular signals显示文摘A polynomial-rooting based fourth-order cumulant algorithm is presented for direction-of-arrival(DOA) estimation of second-order fully noncircular source signals, using a uniform linear array(ULA). This algorithm inherits all merits of its spectralsearching counterpart except for the applicability to arbitrary array geometry, while reducing considerably the computation cost.Simulation results show that the proposed algorithm outperforms the previously developed closed-form second-order noncircular ESPRIT method, in terms of processing capacity and DOA estimation accuracy, especially in the presence of spatially colored noise. | Lei Shen Zhiwen Liu Xiaoming Gou Yougen Xu | 2014 | Journal of Systems Engineering and Electronics2014，25，6： | 5 |

| 10 | Quantum Field Theory of the Universe in the Induced Gravity显示文摘The quantum field theory on the universe in the induced theory of gravity is discussed in detail.After the wave function of the universes was regarded as a universe field operator in the minisuperspace,not only the difficulty in a probabilistic interpretation in the quantum cosmology can be circumvented,but also the conclusion of the multiple production of universes is obtained.We find the distribution of these universes created from‘nothing’is the planck distribution. | SHEN Yougen | 1995 | Chinese Physics Letters1995，12，8： | 0 |
| 11 | Effects of chemical coating with Ni on electrochemical properties of Mg_2Ni hydrogen storage alloys显示文摘The effects of nickel coating on the electrochemical properties of Mg2Ni hydrogen storage alloys are presented in this paper. X-ray diffraction (XRD) and scanning electron microscope (SEM) techniques were employed to examine the crystal structure and surface morphologies of the bare and Ni-coated Mg2Ni alloys. The electrochemical properties of alloys were characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results showed that Ni coating not only decreased the charge transfer resistance, but also decreased the H atom diffusion resistance for Mg2Ni alloys. It was also found that Ni coating effectively improved the discharge capacity, but decreased the cycling performance of the as-synthesized Ni-coated Mg2Ni alloys. The discharge current has a great impact on the cycling performance of the as-synthesized Ni-coated Mg2Ni alloys. | TANG Yougen SHEN Jianbin XU Yijun JIANG Jinzhi | 2007 | Rare Metals2007，26，6： | 0 |
