| 1 | Survey of UAV motion planning显示文摘Motion planning is a vital module for unmanned aerial vehicles(UAVs),especially in scenarios of autonomous navigation and operation.This survey delivers some recent state-of-the-art UAV motion planning algorithms and related applications.The logic flow of this survey is divided as the path finding,which is the front-end of most motion planning systems,and the trajectory optimisation,which usually serves as the back-end.Motivation,methodology,problem formulation and derivation are given in this survey,in detail.Finally,a section about real-world applications is given,where roles and effectiveness of most popular motion planning methods are revealed. | Lun Quan Luxin Han Boyu Zhou Shaojie Shen Fei Gao | 2020 | IET Cyber-Systems and Robotics2020，2，1： | 2 |
| 2 | Efficient degradation of organic pollutants by S-NaTaO_(3)/biochar under visible light and the photocatalytic performance of a permonosulfate-based dual-effect catalytic system显示文摘Removing large concentrations of organic pollutants from water efficiently and quickly under visible light is essential to developing photocatalytic technology and improving solar energy efficiency.This study used a simple hydrothermal method to prepare a non-metallic,S-doped NaTaO_(3)(S-NTO) photocatalyst,which was then loaded onto biochar (BC) to form a S-NTO/BC composite photocatalyst.After uniform loading onto BC,the S-NTO particles transformed from cubic to spherical.The photogenerated electron-hole pair recombination probability of the composite photocatalyst was significantly lower than those of the NTO particles.The light absorption range of the catalyst was effectively widened from 310 nm UV region to visible region.In addition,a dual-effect catalytic system was constructed by introducing peroxymonosulfate (PMS) into the environment of the pollution to be degraded.The Rhodamine B,Methyl Orange,Acid Orange 7,tetracycline,and ciprofloxacin degradation efficiency at 40 mg/L reached 99.6%,99.2%,84.5%,67.1%,and 70.7%,respectively,after irradiation by a 40 W lamps for 90 min.The high-efficiency visible-light catalytic activity of the dual-effect catalytic system was attributed to doping with non-metallic sulfur and loading of catalysts onto BC.The development of this dual-effect catalytic system provides new ideas for quickly and efficiently solving the problem of high-concentration organic pollution in aqueous environments,rationally and fully utilizing solar energy,and expanding the application of photocatalytic technology to practice. | Yuehui Tai Jinlong Sun Haoran Tian Fuyue Liu Boyu Han Wei Fu Zhangpei Liu Xiuye Yang Qifeng Liu | 2023 | Journal of Environmental Sciences2023，，3： | 1 |

| 4 | Effect of Extrusion Combination Types on Microstructure and Mechanical Properties of the AZ31/GW103K Bimetallic Composite Plates显示文摘The AZ31/GW103 K bimetallic composite plates were prepared by co-extrusion of different combination types(sandwich extrusion type and double semicircle extrusion type),and effects of different extrusion combination types on the microstructure and mechanical properties of bimetallic composite plates were systematically investigated.The results show that both the AZ31/GW103 K bimetallic composite plates prepared by different extrusion combination types have good metallurgical bonding,and changing the combination type does not affect the thickness of the interfacial transition layer of composite plates.Compared with the monolithic AZ31 and GW103 K extruded plates,co-extrusion can promote the dynamic recrystallization(DRX)of AZ31 and GW103 K components in composite plates,and double semicircular extrusion type has a better promotion effect on the DRX than sandwich extrusion type.In addition,the texture of AZ31 in both monolithic AZ31 and AZ31/GW103 K/AZ31(A/G/A)plates is a typical(0002)basal texture,while that in the AZ31/GW103 K(A/G)composite plate shifts to the tangent direction(TD)of extruded plate.Compared with the monolithic AZ31 extruded plate,both the yield strength and tensile strength of A/G and A/G/A bimetallic composite plates are significantly improved.The strength of A/G/A composite plate is higher than that of A/G composite plate,but its elongation is worse.Meanwhile,co-extrusion reduces the dislocation density of AZ31 and GW 103 K components in composite plates,and different extrusion combination types also affect the dislocation density. | Yunpeng Meng Boyu Lin Lifei Wang Jianfeng Fan Shangzhou Zhang Liwei Lu Hans Jφrgen Roven Hua Zhang | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，12： | 0 |
