| 1 | Survey of recent progress in semantic image segmentation with CNNs显示文摘In recent years, convolutional neural networks(CNNs) are leading the way in many computer vision tasks, such as image classification, object detection, and face recognition. In order to produce more refined semantic image segmentation, we survey the powerful CNNs and novel elaborate layers, structures and strategies, especially including those that have achieved the state-of-the-art results on the Pascal VOC 2012 semantic segmentation challenge. Moreover, we discuss their different working stages and various mechanisms to utilize the structural and contextual information in the image and feature spaces. Finally, combining some popular underlying referential methods in homologous problems, we propose several possible directions and approaches to incorporate existing effective methods as components to enhance CNNs for the segmentation of specific semantic objects. | Qichuan GENG Zhong ZHOU Xiaochun CAO | 2018 | Science China(Information Sciences)2018，61，5： | 7 |
| 2 | Preparation of High-Strength Al–Mg–Si/Al_2O_3 Composites with Lamellar Structures Using Freeze Casting and Pressureless Infiltration Techniques显示文摘Lamellar porous alumina scaffolds with the initial solid loadings of 20, 25, and 30 vol% were prepared by freeze casting using 5 lm alumina powders. With the addition of 3 wt% Mg O–Al2O3–Si O2 nanopowders in a eutectic composition as sintering aid, the maximum compressive strength of the sintered scaffolds reached(64 ± 2) MPa after sintering at 1,773 K for 2 h. The lamellar porous scaffolds were then filled with a molten Al–12Si–10 Mg alloy(in wt%)by pressureless infiltration at 1,223 K in a N2 atmosphere, yielding the shell-like structure of the composites. The compressive strength of the upper part composite with the initial 30 vol% solid loading reached(1,190 ± 50) MPa, which was about 3.5 times as large as that of the matrix alloy. | Ping Shen Juwei Xi Yujie Fu Alateng Shaga Chang Sun Qichuan Jiang | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，5： | 7 |
| 3 | Manufacture of Nano-Sized Particle-Reinforced Metal Matrix Composites:A Review显示文摘Compared to the micro-sized particle-reinforced metal matrix composites, the nano-sized particle-reinforced metal matrix composites possess superior strength, ductility, and wear resistance, and they also exhibit good elevated temperature properties. Therefore, the nano-sized particle-reinforced metal matrix composites are the new potential material which could be applied in many industry fields. At present, the nano-sized particle-reinforced metal matrix composites could be manufactured by many methods. Different kinds of metals, predominantly Al, Mg, and Cu, have been employed for the production of composites reinforced by nano-sized ceramic particles such as carbides, nitrides, and oxides. The main drawbacks of these synthesis methods are the agglomeration of the nano-sized particles and the poor interface between the particles and the metal matrix. This work is aimed at reviewing the ex situ and in situ manufacturing techniques. Moreover, the distinction between the two methods is discussed in some detail. It was agreed that the in situ manufacturing technique is a promising method to fabricate the nano-sized particle-reinforced metal matrix composites. | Dongshuai Zhou Feng Qiu Huiyuan Wang Qichuan Jiang | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，5： | 6 |
| 4 | Aging Behavior of Nano-SiC/2014Al Composite Fabricated by Powder Metallurgy and Hot Extrusion Techniques显示文摘The aging-hardening kinetics of powder metallurgy processed 2014Al alloy and its composite have been studied. The existence of n-SiC particulates leads to the increase of peak hardness. Interestingly, the aginghardening peak of the composite takes place at earlier time than that of the unreinforced alloy. Transmission electron microscopy(TEM) studies indicated that the major precipitation phases are Al_5Cu_2Mn_3 and θ′(Al_2Cu). Besides, Ω phase appeared in both specimens at peak hardening condition, which has been rarely observed previously in aluminum metal matrix composites without Ag. Accelerated aging kinetics and increased peak hardness may be attributed to the higher dislocation density resulted from the mismatch of coefficients of thermal expansion between n-SiC and 2014Al matrix. The results are beneficial to fabricating high performance composites for the application in automobile field such as pistons, driveshaft tubes, brake rotors, bicycle frames, railroad brakes. | Zhiguo Wang Chuanpeng Li Huiyuan Wang Xian Zhu Min Wu Jiehua Li Qichuan Jiang | 2016 | Journal of Materials Science & Technology2016，32，10： | 4 |
| 5 | sEMG based quantitative assessment of acupuncture on Bell's palsy:an experimental study显示文摘Acupuncture is a traditional Chinese therapeutic method, recognized by western medicine as an important complementary therapy. However, the efficacy assessment of this traditional intervention has been mainly empirical rather than scientific. In this paper, we propose a surface electromyography(s EMG) based approach for quantitative assessment of acupuncture on Bell's palsy. The assessment is made by comparing the muscle activities of healthy with diseased ones. A feature-vector of four individual s EMG features is introduced for more comprehensive representation of muscle activity. A clustering technique is then proposed to calculate quantitative differences between the muscle activities of the healthy and diseased sides. A regressive model is also proposed to predict the recovery trend of a patient based on the quantitative assessments during his/her clinical acupuncture history. As reported in the paper, a total of 20 selected Bell's palsy patients have participated in the extensive experiments that were conducted to verify the performance of the proposed method. | HAN JianDa XIONG AnBin ZHAO XinGang DING QiChuan CHEN YiGuo LIU GuangJun | 2015 | Science China(Information Sciences)2015，58，8： | 3 |
| 6 | Effect of Cr Content on the Compression Properties and Abrasive Wear Behavior of the High-Volume Fraction(TiC–TiB_2)/Cu Composites显示文摘The(TiC–TiB2)/Cu composites with 50 vol% Ti C–Ti B2 ceramic particles were successfully fabricated by the combustion synthesis and hot press consolidation in a Cu–Ti–B4C–Cr system. The effects of the Cr content on the microstructures, hardness, compression properties, and abrasive wear behaviors of the composites were investigated. The final products consist of only Cu, Ti C, and Ti B2 phases, and the ceramic particles are distributed uniformly in these composites. The size of the ceramic particles decreases with Cr addition. As the Cr content increases, the yield strength,ultimate compression strength, microhardness, and abrasive wear resistance of the composites increase, and the fracture strain decreases. | Feng Qiu Yue Han Ai Cheng Jianbang Lu Qichuan Jiang | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，5： | 2 |
