Method for determining number of coherent signals in the presence of colored noise

引用

Journal of Systems Engineering and Electronics 2010年第1期21卷 27-30页

作者： jiaqi Zhen, Xicai si, and Lutao Liu College of Information & Communication Engineering, Harbin Engineering University, Harbin 150001, P. R. China College of Information & Communication Engineering Harbin Engineering University Harbin 150001 P. R. China

The approach of estimating the number of signals based on information theoretic criteria has good performance in the assumption of white noise, but it always leads to false estimation of the coherent sources in colored noise. An approach combining the combined information theoretic criteria and eigen- value correction, is presented to determine number of signals. The method uses maximum likelihood （ML） and information theoretic criteria to estimate coherent signals alternately, then eliminate the inequality of the eigenvalues caused by colored noise by correcting the noise eigenvalues. The computer simulation results prove the effective performance of the method.

Preparation of Novel Complex Nano-Structured Gold Catalyst Au@T<sub>i</sub>O<sub>2</sub>/MCM-22, Characterization and Remarkably Catalytic Performance for Cyclohexane Oxidation

引用

Modern Research in Catalysis 2017年第1期6卷 15-29页

作者： jiaqi si Lin Li Yanji Zhang Ji-Cheng Zhou Wenbing Ouyang Key Laboratory of Green Catalysis and Reaction Engineering Department of Education College of Chemical Engineering Xiangtan University Xiangtan China

A novel complex nano-structured Au@TiO2 gold catalyst has been prepared. Au precursor could be transformed into Au@TiO2/MCM-22 with the complex nano-structured using two different methods. Samples were characterized by XRD, FT-IR, UV-vis, TEM, ICP-AES and N2 adsorption-desorption. It is found that gold was anchored on the TiO2/MCM-22 as small size and uniform particles with the average diameters in the range of 5 - 9 nm. Catalytic results show that such nano-gold catalysts display excellent catalytic performance for cyclohexane oxidation. Au@TiO2/MCM-22 catalyst with the gold content of 0.5 wt% exhibits extremely exceptionally catalytic activity (12.81%) and high turnover frequency (52,121 h-1), which may be ascribed to the synergistic effects of Au and TiO2 in the complex nano-structured catalyst Au@TiO2/ MCM-22. Because of the strong metal support interaction, aggregation of active sites (Au nanoparticles) during the oxidation reaction is effectively prohibited and the catalytic activity is essentially retained.

Properties of collective flow and pion production in intermediate-energy heavy-ion collisions with a relativistic quantum molecular dynamics model

引用

Nuclear Science and Techniques 2024年第1期35卷 155-169页

作者： si-Na Wei Zhao-Qing Feng School of Physics and Optoelectronics South China University of TechnologyGuangzhou 510640China

The relativistic mean-field approach was implemented in the Lanzhou quantum molecular dynamics transport model(***). Using the ***, the properties of collective flow and pion production were investigated systematically for nuclear reactions with various isospin asymmetries. The directed and elliptic flows of the *** are able to describe the experimental data of STAR Collaboration. The directed flow difference between free neutrons and protons was associated with the stiffness of the symmetry energy, that is, a softer symmetry energy led to a larger flow difference. For various collision energies, the ratio between the π^(-) and π^(+) yields increased with a decrease in the slope parameter of the symmetry energy. When the collision energy was 270 MeV/nucleon, the single ratio of the pion transverse momentum spectra also increased with decreasing slope parameter of the symmetry energy in both nearly symmetric and neutron-rich ***, it is difficult to constrain the stiffness of the symmetry energy with the double ratio because of the lack of threshold energy correction on the pion production.
