| 1 | High-precision pose measurement method in wind tunnels based on laser-aided vision technology显示文摘The measurement of position and attitude parameters for the isolated target from a highspeed aircraft is a great challenge in the field of wind tunnel simulation technology.In this paper,firstly, an image acquisition method for small high-speed targets with multi-dimensional movement in wind tunnel environment is proposed based on laser-aided vision technology.Combining with the trajectory simulation of the isolated model, the reasonably distributed laser stripes and selfluminous markers are utilized to capture clear images of the object.Then, after image processing,feature extraction, stereo correspondence and reconstruction, three-dimensional information of laser stripes and self-luminous markers are calculated.Besides, a pose solution method based on projected laser stripes and self-luminous markers is proposed.Finally, simulation experiments on measuring the position and attitude of high-speed rolling targets are conducted, as well as accuracy verification experiments.Experimental results indicate that the proposed method is feasible and efficient for measuring the pose parameters of rolling targets in wind tunnels. | Liu Wei Ma Xin Li Xiao Chen Ling Zhang Yang Li Xiaodong Shang Zhiliang Jia Zhenyuan | 2015 | Chinese Journal of Aeronautics2015,28,4: | 11 |
| 2 | Lopingian mixed floras from Linxi Formation in Soron area,Inner Mongolia显示文摘A lot of well-preserved plants from the Linxi Formation are collected in the Soron area,Inner Mongolia,consisting of 34 species of 16 genera. They are Late Permian in age. The flora is characterized by a lot of Angaran plants,such as Paracalamites,Comia,Rhachiphyllum,Iniopteris,Rufloria,etc. Some Cathaysian elements,such as Lobatannularia lingulata,L. multifolia,Fascipteris Cathaysiantus,F. densata,Taeniopteris szei,Cladophlebis liulinensis and C. permica,are also mixed within the present flora. This indicates that the Soron of Inner Mongolia was located in the sector between the Angaran and Cathysian floristic provinces in Lopingian. It is beneficial for depicting the location and the evolution of the Solenker--Xar Moron suture zone in the phytogeographic view. The transmigration of tropical and subtropical Cathaysian plants to the north indicates that the Paleoasian Ocean was closed during the late Permian along the suture zone. | ZHANG Dejun SUN Yuewu DING Haisheng YANG Zhenyuan TANG Lijing | 2014 | Global Geology2014,17,2: | 10 |
| 3 | Switching variability index based multiple strategy CFAR detector显示文摘A switching variability index(SVI) constant false alarm rate(CFAR) detector is proposed for improving the detection performance of VI-CFAR detectors in multiple targets backgrounds. When the presence of non-homogeneity in CFAR reference windows is indicated by a VI-CFAR detector, a switchingCFAR detector is introduced to optimize the performance of the VI-CFAR detector in homogeneous, multiple targets and clutter edge backgrounds. The structure and parameters selection method of the SVI-CFAR detector is presented. Comparisons with classic CFAR detectors and recently proposed detectors are also given. Theoretical analysis and simulation results show that SVICFAR detector maintains the good performance of the VI-CFAR detector in homogeneous and clutter edge backgrounds, while greatly improving the capacity of anti-multi targets. | Yang Li Zhenyuan Ji Bingfei Li Gil Alterovitz | 2014 | Journal of Systems Engineering and Electronics2014,25,4: | 4 |
| 4 | Structured hierarchical Mn–Co mixed oxides supported on silicalite-1 foam catalyst for catalytic combustion显示文摘Silicalite-1(S1)foam was functionalized by supporting manganese-cobalt(Mn-Co)mixed oxides to develop the structured hierarchical catalyst(Mn-Co@SlF)for catalytic combustion for the first time.The self-supporting S1 foam with hierarchical porosity was prepared via hydrothermal synthesis with polyurethane(PU)foam as the template.Subsequently,Mn-Co oxide nano sheets were uniformly grown on the surface of S1 foams under hydrothermal conditions to prepare the structured hierarchical catalyst with specific surface area of 354 m^2·g^-1,micropore volume of 0.141 cm^3·g^-1 and total pore volume of 0.217 cm3·g^-1,as well as a good capacity to adsorb toluene(1.7 mmol·g^-1 at p/p0=0.99).Comparative catalytic combustion of toluene of over developed structured catalyst Mn-Co@SlF was performed against the control catalysts of bulk Mn-Co@S1(i.e.,the crushed Mn-Co@SlF)and unsupported Mn-Co oxides(i.e.,Mn-Co).Mn-Co@SlF exhibited comparatively the best catalytic performance,that is,complete and stable toluene conversion at 2480 C over 65 h due to the synergy between Mn-Co oxides and S1 foam,which provided a large number of oxygen vacancies,high redox capacity.In addition,the hierarchical porous structure also improved the accessibility of active sites and facilitated the global mass transfer across the catalyst bed,being beneficial to the catalysis and catalyst longevity. | Yanan Guan Hengyu Shen Xing Guo Boyang Mao Zhenyuan Yang Yangtao Zhou He Liang Xiaolei Fan Yilai Jiao jinsong Zhang | 2020 | Chinese Journal of Chemical Engineering2020,28,9: | 3 |
| 5 | Global Synchronization of Stochastically Disturbed Memristive Neurodynamics via Discontinuous Control Laws显示文摘This paper presents the theoretical results on the master-slave(or driving-response) synchronization of two memristive neural networks in the presence of additive noise. First,a control law with a linear time-delay feedback term and a discontinuous feedback term is introduced. By utilizing the stability theory of stochastic differential equations, sufficient conditions are derived for ascertaining global synchronization in mean square using this control law. Second, an adaptive control law consisting of a linear feedback term and a discontinuous feedback term is designed to achieve global synchronization in mean square, and it does not need prior information of network parameters or random disturbances. Finally, simulation results are presented to substantiate the theoretical results. | Zhenyuan Guo Shaofu Yang Jun Wang | 2016 | IEEE/CAA Journal of Automatica Sinica2016,3,2: | 2 |
| 6 | A Portable Noncontact Profile Scanning System for Aircraft Assembly显示文摘Three-dimensional(3D)profile scanning plays a crucial role in the inspection of assembled large aircraft.In this paper,to achieve noncontact automatic measurements of the high-reflective profiles of large-scale curved parts and components,an automated noncontact system and method with high accuracy and high efficiency are presented.First,a hybrid 3D coordinate measurement system based on proximity sensors and cameras is proposed to obtain noncontact measurements while avoiding the influence of high reflection on the measurement accuracy.A hybrid measurement model that combines the one-dimensional distances measured by the proximity sensors and the 3D information obtained by cameras is proposed to determine high-accuracy 3D coordinates of the measured points.Then,a profile-driven 3D automated scanning method and strategy are designed to rapidly scan and reconstruct the profile within the effective range without scratching the profile or exceeding the measurement range of the proposed system.Finally,experiments and accuracy analyses are performed in situ on an assembled tailplane panel(approximately 1760 mm×460 mm).The automated scanning process is completed in a timeframe of 208s with an average error of less than 0.121 mm for profile reconstruction.Therefore,the proposed method is promising considering both the high accuracy and high efficiency requirements of profile inspections for large aircraft. | Bing Liang Wei Liu Kun Liu Mengde Zhou Yang Zhang Zhenyuan Jia | 2022 | Engineering2022,8,8: | 2 |

| 14 | Carrier Dynamics and Surface Reaction Boosted by Polymer-based Single-atom Photocatalysts显示文摘Carrier dynamics and surface reaction are two critical processes for determining the performance of photocatalytic reaction.Highly designable polymer-based photocatalysts have shown promising protectives in energetic and environmental applications.In this prospective,we first distinguished the differences of physiochemical properties between polymer-based semiconductors and traditional inorganic semiconductors.Then,the effects of single-atom sites on the charge dynamics and reaction kinetics of polymer-based photocatalysts are further elaborated.Time(excitation)-space(wavefunction)population analysis,which can provide relevant information to clarify the structure-excitation relationships after introducing the single atom sites was also reviewed.In the future,with the further development of artificial intelligence,the establishment of an energy function with a regression accuracy close to or reaching the level of density functional theory is highly desired to infer the energetic diagram of the photocatalytic systems at the excited states.Furthermore,coordination structures,interaction with inorganic semiconductors,photocatalytic stability and solvent effects should also be carefully considered in the future studies of polymer-based photocatalyst. | TENG Zhenyuan YANG Hongbin ZHANG Qitao OHNO Teruhisa | 2022 | Chemical Research in Chinese Universities2022,38,5: | 1 |
