| 1 | A Survey on Deep Learning-based Fine-grained Object Classification and Semantic Segmentation显示文摘The deep learning technology has shown impressive performance in various vision tasks such as image classification, object detection and semantic segmentation. In particular, recent advances of deep learning techniques bring encouraging performance to fine-grained image classification which aims to distinguish subordinate-level categories, such as bird species or dog breeds. This task is extremely challenging due to high intra-class and low inter-class variance. In this paper, we review four types of deep learning based fine-grained image classification approaches, including the general convolutional neural networks(CNNs), part detection based,ensemble of networks based and visual attention based fine-grained image classification approaches. Besides, the deep learning based semantic segmentation approaches are also covered in this paper. The region proposal based and fully convolutional networks based approaches for semantic segmentation are introduced respectively. | Bo Zhao Jiashi Feng Xiao Wu Shuicheng Yan | 2017 | International Journal of Automation and computing2017，14，2： | 36 |

| 4 | Crimp feasibility of AZ31 magnesium alloy wide plate at warm temperatures responding to asymmetry显示文摘The crimp feasibility of AZ31 Mg alloy wide plate responding to asymmetry and anisotropy at different temperatures was conducted by bending experiments and numerical simulation.Through the microstructural characteristic,mechanical properties,EBSD and FEM analysis,the results indicated that{10-12}twins and pyramidal(a)slip were dominated at the inner surface layer of the plate,while prismatic and pyramidal(a)slips were controlled at the outer layer when bending at 100℃,and their quantity decreased as the temperature elevation and vanished at 200℃.The flexural deflection increased gradually with the augment of flexural temperature,while the fracture stress weakened.A large number of twins nucleated and grew in the coarse grain,causing major distribution proportion of high angular grain boundaries(HAGBs)at the compression part,which could improve its flexural properties and affect subsequent strain contours,twins and recrystallization distribution.The offset of the neutral layer declined from 1.4125 mm to 0.7261 mm with the temperature rising from 100℃to 250℃when bending,while it was concentrated on 0.0338-0.0481 mm when coiling,accounting for 0.26%-0.37%of the plate thickness.At last,the reel diameter descended with increasing the temperature and coiling rate. | Fangkun Ning Qichi Le Jiashi Yan Yonghui Jia | 2022 | Journal of Magnesium and Alloys2022，10，3： | 0 |
