| 1 | Transformers in computational visual media:A survey显示文摘Transformers,the dominant architecture for natural language processing,have also recently attracted much attention from computational visual media researchers due to their capacity for long-range representation and high performance.Transformers are sequence-to-sequence models,which use a selfattention mechanism rather than the RNN sequential structure.Thus,such models can be trained in parallel and can represent global information.This study comprehensively surveys recent visual transformer works.We categorize them according to task scenario:backbone design,high-level vision,low-level vision and generation,and multimodal learning.Their key ideas are also analyzed.Differing from previous surveys,we mainly focus on visual transformer methods in low-level vision and generation.The latest works on backbone design are also reviewed in detail.For ease of understanding,we precisely describe the main contributions of the latest works in the form of tables.As well as giving quantitative comparisons,we also present image results for low-level vision and generation tasks.Computational costs and source code links for various important works are also given in this survey to assist further development. | Yifan Xu Huapeng Wei Minxuan Lin Yingying Deng Kekai Sheng Mengdan Zhang Fan Tang Weiming Dong Feiyue Huang Changsheng Xu | 2022 | Computational Visual Media2022，8，1： | 6 |
| 2 | Effect of Brazing Conditions on Microstructure and Mechanical Properties of Al_2O_3/Ti—6Al—4V Alloy Joints Reinforced by TiB Whiskers显示文摘Al2O3and Tie6Ale4V alloy were brazed with AgeCueTi+B fillers in different brazing conditions.Effects of brazing temperature,holding time and additive Ti content on joints microstructure and shear strength were investigated by scanning electron microscopy,energy dispersive spectrometry,X-ray diffraction,transmission electron microscopy and shear testing.Results indicate that TiCu and Ti(Cu,Al) decrease,but Ti2Cu and Ti2(Cu,Al) increase in brazing seam with increasing brazing temperature,holding time and additive Ti content.Area consisting of Ti3(Cu,Al)3O and TiO near Al2O3becomes gradually discontinuous from continuity when brazing temperature rises or holding time extends.As Ti additive content increases,TiO is absent near Al2O3;area consisting of only Ti3(Cu,Al)3O thickens.TiB whiskers are in situ synthesized by Ti and B atoms during brazing process.The brazing temperature,holding time and additive Ti content on joints microstructure influence the joints shear strength directly.The shear strength of joints,obtained at 850℃ holding for10 min,reaches the maximum of 78 MPa.According to the experimental results,phase diagram and thermodynamics calculation,the interface evolution mechanism of the Al2O3/Tie6Ale4V alloy joint was analyzed. | Minxuan Yang Peng He Tiesong Lin | 2013 | Journal of Materials Science & Technology2013，29，10： | 5 |
