| 1 | An interpolating boundary element-free method (IBEFM) for elasticity problems显示文摘The paper begins by discussing the interpolating moving least-squares (IMLS) method. Then the formulae of the IMLS method obtained by Lancaster are revised. On the basis of the boundary element-free method (BEFM), combining the boundary integral equation method with the IMLS method improved in this paper, the interpolating boundary element-free method (IBEFM) for two-dimensional elasticity problems is presented, and the corresponding formulae of the IBEFM for two-dimensional elasticity problems are obtained. In the IMLS method in this paper, the shape function satisfies the property of Kronecker δ function, and then in the IBEFM the boundary conditions can be applied directly and easily. The IBEFM is a direct meshless boundary integral equation method in which the basic unknown quantity is the real solution to the nodal variables. Thus it gives a greater computational precision. Numerical examples are presented to demonstrate the method. | REN HongPing 1 , CHENG YuMin 2 & ZHANG Wu 1 1 School of Computer Engineering and Science, Shanghai University, Shanghai 200072, China 2 Shanghai Institute of Applied Mathematics and Mechanics, Shanghai University, Shanghai 200072, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，4： | 5 |

| 6 | Perceptual Image Outpainting Assisted by Low-Level Feature Fusion and Multi-Patch Discriminator显示文摘Recently,deep learning-based image outpainting has made greatly notable improvements in computer vision field.However,due to the lack of fully extracting image information,the existing methods often generate unnatural and blurry outpainting results in most cases.To solve this issue,we propose a perceptual image outpainting method,which effectively takes the advantage of low-level feature fusion and multi-patch discriminator.Specifically,we first fuse the texture information in the low-level feature map of encoder,and simultaneously incorporate these aggregated features reusability with semantic(or structural)information of deep feature map such that we could utilizemore sophisticated texture information to generate more authentic outpainting images.Then we also introduce a multi-patch discriminator to enhance the generated texture,which effectively judges the generated image from the different level features and concurrently impels our network to produce more natural and clearer outpainting results.Moreover,we further introduce perceptual loss and style loss to effectively improve the texture and style of outpainting images.Compared with the existing methods,our method could produce finer outpainting results.Experimental results on Places2 and Paris StreetView datasets illustrated the effectiveness of our method for image outpainting. | Xiaojie Li Yongpeng Ren Hongping Ren Canghong Shi Xian Zhang Lutao Wang Imran Mumtaz Xi Wu | 2022 | Computers, Materials & Continua2022，，6： | 0 |
| 7 | Woody Plants as Resources in China, Their Conservation and Use显示文摘This paper deals with species of the woody plants in China and their conservation problems. The floristic elements of woody plants was computed and the results indicate that the elements of Tropical Asia accounts for the largest number of genus while the proportion of the elements of Temperate Asia is relatively small. For each of eight vegetation region, the number of woody plants was established and a list of the endangered and rare species was compiled. In regard to the problems of protecting the endangered precious and rare species at present we propose some workable solutions. | Ren Xianwei Liang Hongping Zhang YujunForest Resources College.
