| 1 | Orientation of cylindrical particles in gas-solid circulating fluidized bed显示文摘The orientation of cylindrical particles in a gas-solid circulating fluidized bed was investigated by establishing a three-dimensional Euler-Lagrange model on the basis of rigid kinetics, impact kinetics and gas-solid two-phase flow theory. The resulting simulation indicated that the model could well illustrate the orientation of cylindrical particles in a riser during fluidization. The influences of bed structure and operation parameters on orientation of cylindrical particles were then studied and compared with related experimental results. The simulation results showed that the majority of cylindrical particles move with small nutation angles in the riser, the orientation of cylindrical particles is affected more obviously by their positions than by their slenderness and local gas velocities. The simulation results well agree with experiments, thus validating the proposed model and computation. | Jie cai Qihe Li Zhulin Yuan | 2012 | Particuology2012，10，1： | 5 |
| 2 | Containment control of multi-agent systems with nonvanishing disturbance via topology reconfiguration显示文摘Dear editor,Multi-agent systems(MASs)are ubiquitous in natural as well as artificial systems.Over the past several decades,an increasing number of researchers have devoted attention to distributed cooperative control problems of MASs such as mobile robots[1]and unmanned aircraft[2].Recently,different containment control problems with multiple leaders have arisen,including finite-time coordination[3,4],formation producing[5],and heterogeneous MASs[6].In previous studies,the objective of containment control has been to make the followers converge to the convex hull formed by the leaders[7,8].However,in real-world applications for containment control of MASs,disturbances from the environment make it more reasonable to change the aforementioned convex hull into its interior points because the followers sometimes are not allowed to converge to the boundaries. | Qihe SHAN Fei TENG Tieshan LI C.L.Philip CHEN | 2021 | Science China(Information Sciences)2021，64，7： | 2 |

| 19 | Partition sampling strategy for robot motion planning under uncertainty显示文摘In order to solve the sensing and motion uncertainty problem of motion planning in narrow passage environment,a partition sampling strategy based on partially observable Markov decision process(POMDP)was proposed.The method combines partition sampling strategy and can improve the success rate of the robot motion planning in the narrow passage.Firstly,the environment is divided into open area and narrow area by using a partition sampling strategy,and generates the initial trajectory of the robot with fewer sampling points.Secondly,the method can calculate a local optimal solution of the initial nominal trajectory by solving POMDP problem,and iterates an overall optimal trajectory of robot motion.The proposed method follows the general POMDP solution framework,in which the belief dynamics is approximated by an extended Kalman filter(EKF),and the value function is represented by an effective quadratic function in the belief space near the nominal trajectory.Using a belief space variant of iterative linear quadratic Gaussian(iLQG)to perform the value iteration,which results in a linear control policy over the belief space that is locally optimal around the nominal trajectory.A new nominal trajectory is generated by executing the control strategy iteration,and the process is repeated until it converges to a locally optimal solution.Finally,the robot gets the optimal trajectory to safely pass through a narrow passage.The experimental results show that the proposed method can efficiently improves the performance of motion planning under uncertainty. | Cao Qihe Li Qinghua Qiu Shubo Han Fengjian Feng Chao | 2021 | The Journal of China Universities of Posts and Telecommunications2021，28，3： | 0 |
| 20 | Plant Community Diversity in Dongtian Forest Park,Meizhou City,South China显示文摘Dongtian Park is a forest park in Dongtian Lake Ecological Tourism Resort in Meizhou City,South China.Through investigation and analysis of sample methods of the forest community structure and plant diversity in this park,the results showed that there were 181 plant species,belonging to 138 genera in 76 families,including 48 trees,60 shrubs,36 herbs and 37 lianas.The flora is a subtropical evergreen broad-leaved forest with some distinct tropical properties,and evergreen trees accounted for 48.62%of total plant species.The dominant species in the tree layer were Schima superba,Pinus massoniana,Cinnamomum parthenoxylon,etc.,and those in the shrub layer were Bambusa textilis,Aidia cochinchinensis,Rhaphiolepis indica,etc.,and in herb layer were Carex baccans,Adiantum flabellulatum,Cibotium barometz,etc.,and the lianas mainly included Smilax hypoglauca,Callerya dielsiana,Trachelospermum jasminoides,etc.There were few adults of dominant species in the tree layer,S.superba and P.massoniana also lacked seedlings,they would still maintain their dominant position for a quite long period,but Cyclobalanopsis neglecta had sufficient seedling reserves and would be most likely to become a dominant species in future.The community had relatively rich species,many ferns and lianas and complex hierarchy.The evenness,Shannon-Wiener diversity,Pielou uniformity and Simpson index were higher in the shrub layer than in the tree and herb layer,and the Simpson index was the lowest(0.9280)in the herb layer and Shannon-Wiener diversity index was the highest(7.5853)in the liana layer. | Qihe YANG Zhiqi LI Hesheng YANG Lihui MO | 2023 | Agricultural Biotechnology2023，12，2： | 0 |
