| 1 | Characterization of fine organic particulate matter from Chinese cooking显示文摘PM 2.5 samples were collected by a three-stage cascade impactor at two kinds of Chinese restaurants to characterize fine organic particulate matter from Chinese cooking sources. Major individual organic compounds have been quantified by GC/MS, including series of alkanes, n-alkanoic acids, n-alkanals, alkan-2-ones and PAHs. Alkanes and ketones make up a significant fraction of particle-phase organic compounds, ranging from C 11 to C 26, and C 9 to C 19, respectively. In addition, other organic compound classes have been identified, such as alkanols, esters, furans, lactones, amides, and nitriles. The mass concentrations of fine particles, alkanes, n-alkanoic acids and PAHs in air emitted from the Uigur style cooking are hundreds times higher than ambient PM 2.5in Beijing. | HELing-yan HUMin WANGLi HUANGXiao-feng ZHANGYuan-hang | 2004 | Journal of Environmental Sciences2004，16，4： | 11 |
| 2 | Optimal midcourse trajectory cluster generation and trajectory modification for hypersonic interceptions显示文摘The hypersonic interception in near space is a great challenge because of the target's unpredictable trajectory, which demands the interceptors of trajectory cluster coverage of the predicted area and optimal trajectory modification capability aiming at the consistently updating predicted impact point(PIP) in the midcourse phase. A novel midcourse optimal trajectory cluster generation and trajectory modification algorithm is proposed based on the neighboring optimal control theory. Firstly, the midcourse trajectory optimization problem is introduced; the necessary conditions for the optimal control and the transversality constraints are given.Secondly, with the description of the neighboring optimal trajectory existence theory(NOTET), the neighboring optimal control(NOC)algorithm is derived by taking the second order partial derivations with the necessary conditions and transversality conditions. The revised terminal constraints are reversely integrated to the initial time and the perturbations of the co-states are further expressed with the states deviations and terminal constraints modifications.Thirdly, the simulations of two different scenarios are carried out and the results prove the effectiveness and optimality of the proposed method. | Humin Lei Jin Zhou Dailiang Zhai Lei Shao Dayuan Zhang | 2017 | Journal of Systems Engineering and Electronics2017，28，6： | 10 |
| 3 | Coverage-based cooperative target acquisition for hypersonic interceptions显示文摘This paper presents a novel coverage-based cooperative target acquisition algorithm for hypersonic interceptions. Firstly, the difficulties in the hypersonic trajectory prediction are introduced which invalidate the conventionally used predicted impact point based mid-course guidance and seeker acquisition. Secondly, in order to optimally estimate and predict the target trajectory information, the interacting multiple model(IMM) algorithm is used with the constant velocity(CV) model, the constant acceleration(CA) model and the Singer model serving as the model set. The target states are described with the probability density function(PDF) based on the IMM prediction. Thirdly, the interceptor seeker target acquisition model is established which considers the blur edge region of the field of view. The cooperative target acquisition algorithm is designed by maximizing the interceptor seekers cooperative coverage of the target high probability region(HPR). Finally, digital simulations prove the effectiveness of the proposed method and reveal that the real challenge in the hypersonic target acquisition is the poor trajectory prediction accuracy which may further result to the unsteadiness of the interceptor trajectories. | ZHOU Jin LEI HuMin | 2018 | Science China(Technological Sciences)2018，61，10： | 7 |
| 4 | Optimal midcourse trajectory planning considering the capture region显示文摘An optimal midcourse trajectory planning approach that considers the capture region(CR) of the terminal guidance is proposed in this article based on the Gauss pseudospectral method(GPM). Firstly, the planar CR of the proportional navigation in terminal guidance is analyzed and innovatively introduced in the midcourse trajectory planning problems, with the collision triangle(CT) serving as the ideal terminal states parameters of the midcourse phase, and the CR area serving as the robustness against target maneuvers. Secondly, the midcourse trajectory planning problem that considers the path, terminal and control constraints is formulated and the well-developed GPM is used to generate the nominal trajectory that meets the CR demands. The interceptor will reshape the trajectory only when the former CR fails to cover the target, which has loosened the critical demand for frequent trajectory modification. Finally, the simulations of four different scenarios are carried out and the results prove the effectiveness and optimality of the proposed method. | ZHOU Jin SHAO Lei WANG Huaji ZHANG Dayuan LEI Humin | 2018 | Journal of Systems Engineering and Electronics2018，29，3： | 6 |
| 5 | Respective Roles of Short-and Long-Range Interactions in Protein Folding显示文摘A new method was presented to discuss the respective roles of short- and long-range interactions in protein folding. It’s based on an off-lattice model, which is also being called as toy model. Simulated annealing algorithm was used to search its native conformation. When it is applied to analysis proteins 1agt and 1aho, we find that helical segment cannot fold into native conformation without the influence of long-range interactions. That’s to say that long-range interactions are the main determinants in protein folding. | WANGLong-hui HUMin ZHOUHuai-bei LIUJuan | 2004 | Wuhan University Journal of Natural Sciences2004，9，6： | 3 |
| 6 | Nonlinear differential geometric guidance for maneuvering target显示文摘Based on the idea of zeroing the line of sight rate(LOSR),a novel nonlinear differential geometric(DG) law for intercepting the agile target is proposed.In the first part,the DG formulations are utilized to describe the relatively kinematics model of missile and target,and the nonlinear DG guidance(DGG) law is proposed based on the nonlinear control theory to eliminate the influence brought by target.Further,the missile guidance commands are derived to overcome the information loss caused by decoupling condition,the new necessary initial condition is developed to guarantee capture the agile target.Then,the designed nonlinear DGG commands are transformed from an arc-length system to the time domain.A desirable aspect of the designed guidance law is that it does not require rigorous information about target acceleration.Representative numerical results show that the designed guidance law obtain a better performance than the traditional DGG law for agile target. | Jikun Ye Humin Lei Dongfeng Xue Jiong Li Lei Shao | 2012 | Journal of Systems Engineering and Electronics2012，23，5： | 3 |
| 7 | Single and Binary Dye Adsorption of Methylene Blue and Methyl Orange in Alcohol Aqueous Solution via Rice Husk Based Activated Carbon:Kinetics and Equilibrium Studies显示文摘The present work was mainly focused on the single and binary adsorption of methylene blue(MB)and methyl orange(MO)from alcohol aqueous solution over rice husk based activated carbon(RHAC).The study of single dye adsorption equilibrium experiments found that the Langmuir adsorption model was consistent with the adsorption behavior of RHAC on MB and MO,indicating that it was a single layer adsorption.The adsorption behavior con-formed to the pscudo-second-order kinetic model.The binary dye adsorption experiments showed that the Lang-muir-Freundlich model could be applied to describe the adsorption behavior of RHAC on MB and MO.Comparation with the single dye system,the adsorption capacity on the binary dye system was larger,and there was'competitive adsorption'and'synergistic adsorption'effects existed.Meanwhile,the pseudo-second-order kinetic model also fit for the binary dye adsorption behavior. | LI Ying PAN Bo MIAO Hongyan XU Humin LIU Xuefeng SHI Gang | 2020 | Chemical Research in Chinese Universities2020，36，6： | 2 |
| 8 | Prescribed performance neural control to guarantee tracking quality for near space kinetic kill vehicle显示文摘A prescribed performance neural controller to guarantee tracking quality is addressed for the near space kinetic kill vehicle (NSKKV) to meet the state constraints caused by side window detection. Different from the traditional prescribed performance control in which the shape of the performance function is constant, this paper exploits new performance functions which can change the shape of their function according to different symbols of initial errors and can ensure the error convergence with a small overshoot. The neural backstepping control and the minimal learning parameters (MLP) technology are employed for exploring a prescribed performance controller (PPC) that provides robust tracking attitude reference trajectories. The highlight is that the transient performance of tracking errors is satisfactory and the computational load of neural approximation is low. The pseudo rate (PSR) modulator is used to shape the continuous control command to pulse or on-off signals to meet the requirements of the thruster. Numerical simulations show that the proposed method can achieve state constraints, pseudo-linear operation and high accuracy. | ZHANG Tao LI Jiong LI Weimin WANG Huaji LEI Humin | 2019 | Journal of Systems Engineering and Electronics2019，30，3： | 2 |
