| 1 | Segmentation algorithm for Hangzhou white chrysanthemums based on least squares support vector machine显示文摘In order to realize the visual positioning for Hangzhou white chrysanthemums harvesting robot in natural environment,a color image segmentation method for Hangzhou white chrysanthemum based on least squares support vector machine(LS-SVM)was proposed.Firstly,bilateral filter was used to filter the RGB channels image respectively to eliminate noise.Then the pixel-level color feature and texture feature of the image,which was used as input of LS-SVM model(classifier)and SVM model(classifier),were extracted via RGB value of image and gray level co-occurrence matrix.Finally,the color image was segmented with the trained LS-SVM model(classifier)and SVM model(classifier)separately.The experimental results showed that the trained LS-SVM model and SVM model could effectively segment the images of the Hangzhou white chrysanthemums from complicated background taken under three illumination conditions such as front-lighting,back-lighting and overshadow,with the accuracy of above 90%.When segmenting an image,the SVM algorithm required 1.3 s,while the LS-SVM algorithm proposed in this paper just needed 0.7 s,which was better than the SVM algorithm obviously.The picking experiment was carried out and the results showed that the implementation of the proposed segmentation algorithm on the picking robot could achieve 81%picking success rate. | Qinghua Yang Shaoliang Luo Chun Chang Yi Xun Guanjun Bao | 2019 | International Journal of Agricultural and Biological Engineering2019，12，4： | 3 |
| 2 | Synthesis and properties of novel soluble poly(aryl amine ketone)s as high-performance polymers显示文摘A series of poly(aryl amine ketone)s have been obtained by the condensation polymerization of different aromatic dibromides with different primary aromatic diamines via palladium-catalyzed aryl amination reaction. The structures of polymers are characterized by means of FT-IR, 1H NMR spectroscopy, and elemental analysis. The results show an agreement with the proposed structures. DSC and TG measurements show that polymers possess high glass transition temperature (Tg>170℃) and good thermal stability with high decomposition temperatures (TD>450℃). These novel polymers also exhibit good mechanical behaviors and good solubility. | CHANG GuanJun TANG ShiZhen LUO Xuan WANG Qiang XU Zhe ZHANG Lin LIN RunXiong | 2008 | Science China Chemistry2008，51，3： | 2 |

| 7 | Basic Characteristics of a New Flexible Pneumatic Bending Joint显示文摘Several typical flexible pneumatic actuators(FPA) and different mechanical models describing their behaviors have been proposed, however, it is difficult to balance compliance and load capacity in conventional designs, and these models still have limitations in predicting behavior of FPAs. A new flexible pneumatic bending joint(FPBJ) with special anisotropic rigidity structure is proposed. The FPBJ is developed as an improvement with regard to existing types of FPA, and its principal characteristic is derived from the special anisotropic rigidity structure. With this structure, the load capacity in the direction perpendicular to bending plane is strengthened. The structure of the new FPBJ is explained and a mathematical model is derived based on Euler-Bernoulli beam model and Hook's law. To obtain optimum design and usage, some key structure parameters and input-output characteristics are simulated. The simulation results reveal that the relationship between the structure parameters and FPBJ's bending angle is nonlinear. At last, according to the simulation results, the FPBJ is manufactured with optional parameters and tested. The experimental results show that the joint's statics characteristics are reflected by the mathematical model accurately when the FPBJ is deflated. The maximum relative error between simulation and experimental results is less than 6%. However, the model still has limitations. When the joint is inflated, the maximum relative error reaches 20%. This paper proposes a new flexible pneumatic bending joint which has sufficient load capacity and compliance, and the mathematical model provides theoretical guidance for the FPBJ's structure design. | SHAO Tiefeng ZHANG Libin BAO Guanjun LUO Xinyuan YANG Qinghua | 2014 | Chinese Journal of Mechanical Engineering2014，27，6： | 1 |

| 10 | Microstructure and properties of Si_3N_4 ceramics obtained from addition of β-phase seeds and celsian显示文摘The silicon nitride based ceramics obtained by the addition of β-Si3N4 seeds was fabricated using celsian as the additive and by pressureless sintering. The microstructure of the material was observed and analyzed using XRD,SEM,and TEM and the mechanical response of this array microstructure was characterized for flexural strength and fracture behavior. The result shows that the growth of the larger aspect ratio grains initiate mainly from the seeds through the heterogeneous nucleation mechanism during the process of phase transformation,and the intergranular phase BaAl2Si2O8 services as good refractory materials. In contrast to conven-tional processing,a stable bimodal microstructure and complicated component with a lower cost can be achieved using the above-mentioned process theoretically and practically. | Jun Yang Jiqiang Gao Jianfeng Yang Guanjun Qiao Yonghong Luo | 2006 | Journal of University of Science and Technology Beijing2006，13，5： | 0 |
