| 1 | A Deep Learning Approach for Fault Diagnosis of Induction Motors in Manufacturing显示文摘Extracting features from original signals is a key procedure for traditional fault diagnosis of induction motors, as it directly influences the performance of fault recognition. However, high quality features need expert knowledge and human intervention. In this paper,a deep learning approach based on deep belief networks(DBN) is developed to learn features from frequency distribution of vibration signals with the purpose of characterizing working status of induction motors. It combines feature extraction procedure with classification task together to achieve automated and intelligent fault diagnosis. The DBN model is built by stacking multiple-units of restricted Boltzmann machine(RBM), and is trained using layer-bylayer pre-training algorithm. Compared with traditional diagnostic approaches where feature extraction is needed,the presented approach has the ability of learning hierarchical representations, which are suitable for fault classification, directly from frequency distribution of the measurement data. The structure of the DBN model is investigated as the scale and depth of the DBN architecture directly affect its classification performance. Experimental study conducted on a machine fault simulator verifies the effectiveness of the deep learning approach for fault diagnosis of induction motors. This research proposes an intelligent diagnosis method for induction motor which utilizes deep learning model to automatically learn features from sensor data and realize working status recognition. | Si-Yu Shao Wen-Jun Sun Ru-Qiang Yan Peng Wang Robert X Gao | 2017 | Chinese Journal of Mechanical Engineering2017，30，6： | 17 |
| 2 | Laparoscopic hepatectomy by curettage and aspiration:a new technique显示文摘背景 Laparoscopic 外科为最小的侵略和快速的手术后的恢复是有益的。自从在在 1990 年代的肝切除术的 laparoscopic hepatectomy 的使用,它在有效、安全的技术的一些机构 worldwide.Lack 被执行了因为肝办理是在 1998 由刮术和渴望为 laparoscopic hepatectomy 阻止一种新技术它开发的进一步的 development.We 的主要障碍。在这份报纸,我们总共在 7 年 practice.Methods 以后分析这种技术的临床的结果 59 个连续病人在我们的机构从 1998 年 8 月由刮术和渴望经历了 laparoscopic hepatectomy 到 2005 年 1 月。这些病人包括了 33 男性和 26 女性,与 47 年的吝啬的年龄。为肝 transecsion laparoscopic, Peng 的多功能的起作用的析象器(LPMOD ) 被使用。损害在 5 .Procedures 在 19 个病人,在 17 的良性的肝肿瘤,在 18 的 intrahepatic 演算,和另外的肝损害包括了恶意的肝肿瘤在 30 个病人,的包括的本地切除术离开了在 28 的侧面的 segmentectomy,和权利在 1 个 .Results Laparoscopic 手术的 hemihepatectomy 在 57 个病人被完成。二个病人(3.4%) 把操作变换成剖腹术。吝啬的操作时间是 143 分钟,吝啬的 intraoperative 血损失是 456 mi。手术后的医院停留的吝啬的长度是 7 天。复杂并发症在 2 个病人(3.4%) 发生了,并且由刮术没有 perioperative death.Conclusion Laparoscopic hepatectomy,渴望为肝切除术有效、安全。 | CAI Xiu-jun LIANG Xiao WANG Yi-fan YU Hong ZHENG Xue-yong HUANG Di-yu PENG Shu-you Department of General Surgery,Sir Run Run Shaw Hospital,College of Medicine Institute of Minimally Invasive Surgery of Zhejiang University,Hangzhou 310016,China (Cai XJ,Liang X,Wang YF,Yu H,Zheng XY,Huang DY and Peng SY) | 2007 | Chinese Medical Journal2007，，20： | 11 |

| 4 | Key-frame reference selection for non-feedback video communication显示文摘This article addresses the problem of reference picture optimization in video communication over error prone networks. A novel estimation model for transmission distortion is proposed. This model is capable of recursively estimating the overall end-to-end distortion caused by quantization, error propagation, and error concealment. Simulation results show that this model can accurately estimate channel distortion. Then, based on the distortion estimation model, a new non-feedback key-frame reference picture selection (KRPS) algorithm is developed. The optimum reference picture minimizes the transmission distortion under the rate-distortion optimization framework. Extensive experiment results demonstrate that the proposed KRPS algorithm substantially achieves more peak signal to noise ratio (PSNR) gain over traditional prediction, especially in low bit-rate transmission. | PENG Qiang ZHANG Lei YANG Tian-wu CHEN Jim X ZHU Ce | 2009 | The Journal of China Universities of Posts and Telecommunications2009，16，5： | 3 |
