| 1 | Tiny YOLO Optimization Oriented Bus Passenger Object Detection显示文摘The real-time collection of bus passenger object detection is an essential part of developing a smart bus system.The difficulty of object detection mainly lies in the objective factors,such as:clothing,hair style and accessories,light,etc.Traditional object detection met hods with the arti ficial feature ext rac tion suffers from insufficien t st reng th in expression,generalization,and recogni tion rate.The objec t detection met hod based on deep learning mainly uses the convol utio nal neural net work in deep learning to learn features from a large set of data.The learned features can describe the rich infbrmation inherent in the data,and improve the expression ability of the features as well as the recognition accuracy.Due to too many parameters of the Convolutional neural network(CNN)model,the amount of calculation is too large to be opera ted on the vehicle terminal.To reduce calculation burden and improve the operation speed,we employs the depthwise separable convolution method to optimize the convolutional layer of tiny YOLO net work model.It decomposes a complete convolution operation into depthwise convolution and pointwise convolution,thus reducing the parameter amount of the CNN and improving the operation speed.The experiment results reveal that the speed of bus passenger object detection detected by our improved model is 4 times faster than the previous one but with the nearly same detection accuracy. | ZHANG Shuo WU Yanxia MEN Chaoguang LI Xiaosong | 2020 | Chinese Journal of Electronics2020,29,1: | 15 |

| 4 | A Review of Technical Advances,Barriers,and Solutions in the Power to Hydrogen(P2H)Roadmap显示文摘Power to hydrogen(P2H)provides a promising solution to the geographic mismatch between sources of renewable energy and the market,due to its technological maturity,flexibility,and the availability of technical and economic data from a range of active demonstration projects.In this review,we aim to provide an overview of the status of P2H,analyze its technical barriers and solutions,and propose potential opportunities for future research and industrial demonstrations.We specifically focus on the transport of hydrogen via natural gas pipeline networks and end-user purification.Strong evidence shows that an addition of about 10%hydrogen into natural gas pipelines has negligible effects on the pipelines and utilization appliances,and may therefore extend the asset value of the pipelines after natural gas is depleted.To obtain pure hydrogen from hydrogen-enriched natural gas(HENG)mixtures,end-user separation is inevitable,and can be achieved through membranes,adsorption,and other promising separation technologies.However,novel materials with high selectivity and capacity will be the key to the development of industrial processes,and an integrated membrane-adsorption process may be considered in order to produce high-purity hydrogen from HENG.It is also worth investigating the feasibility of electrochemical separation(hydrogen pumping)at a large scale and its energy analysis.Cryogenics may only be feasible when liquefied natural gas(LNG)is one of the major products.A range of other technological and operational barriers and opportunities,such as water availability,byproduct(oxygen)utilization,and environmental impacts,are also discussed.This review will advance readers’understanding of P2H and foster the development of the hydrogen economy. | Guoping Hu Chao Chen Hiep Thuan Lu Yue Wu Congmin Liu Lefu Tao Yuhan Men Guangli He Kevin Gang Li | 2020 | Engineering2020,6,12: | 7 |
| 5 | Combination of laparoscopic and open procedure in dismembered pyeloplasty: report of 51 cases显示文摘Background Laparoscopic dismembered pyeloplasty with less trauma than open surgery is commonly performed for ureteropelvic junction obstruction despite a longer operating time and a long learning curve. We describe in this paper a new technique, which combines laparoscopic and open procedure in dismembered pyeloplasty, that we have developed in 51 patients and achieved excellent results. Methods The surgical procedure can be divided into two steps: laparoscopic dissection of the renal pelvis and proximal ureter transperitoneally; then accomplishing the pyeloplasty through the extended port incision above the ureteropelvic junction as in open surgery. Results All 51 operations were successful without conversion to open surgery. No intraoperative complications were observed. The operating time was 40 minutes to 90 minutes with an average of 57.5 minutes. The estimated blood loss was 15 ml to 30 ml with an average of 21.2 ml. Aberrant artery vessel and primary stricture as the cause of ureteropelvic junction obstruction was noted in 2 and 49 patients, respectively. Thirty-nine patients had fever to differing extents in the 4 days postoperation and no severe infection was observed. Four patients had urinary leakage with their drains being retained for 6 days, 6 days, 5 days or 8 days after the operation. The mean followup was 10.8 months (range 3 months to 36 months). The followup showed good results with symptom resolution in all the patients. Renal ultrasonography demonstrated that the average separation of the collecting systems decreased from preoperative 2.7 cm (range 2.0 cm to 4.7 cm) to postoperative 1.5 cm (range 1.0 cm to 2.3 cm). Excretory urography at 3 months postoperatively showed improved drainage. Of the 51 patients, 35 underwent two or more excretory urograms, demonstrating stable renal function, improved drainage and no evidence of recurrent obstruction. At the last followup visit, each patient was doing well. Conclusions Combination of laparoscopic and open procedure in dismembered pyeloplasty offers a simpler, timesaving method in a minimally invasive fashion with low morbidity for patients with ureteropelvic junction obstruction. Ensuring quality of repair, the method provides a minimally invasive alternative with good results. It is worth future clinical application. | GAO Zhen-li SHI Lei YANG Ming-shan WANG Lin YANG Dian-dong SUN De-kang LIU Qing-zuo MEN Chang-ping WU Ji-tao ZHANG Peng | 2006 | Chinese Medical Journal2006,,10: | 6 |

| 11 | Leaching Effect of Organic Acids on Heavy Metal Contaminated Soil显示文摘With the contamination of soil heavy metals becoming more and more serious,remediation has become a hot issue,and it is of great significance to study the remediation effects of heavy metal contaminated soil. The heavy metal contaminated soil was leached with water,acetic acid and citric acid,and the pH value of the soil after leaching was adjusted with 2% lime water. Finally,the pH value and conductivity of the soil leacheate were determined. The results showed that the best leacheate was citric acid for the remediation of soil contaminated with heavy metals Cu,Cd and Pb,and the optimum leaching concentration was 1. 0,0. 4,0. 7 mol/L,respectively. For the remediation of soil contaminated with Zn,the best leacheate was acetic acid,and the optimal leaching concentration was 1 mol/L. The leaching effect of lime water on heavy metal contaminated soil was positively correlated with the concentration of organic acid,that is,the leaching effect on heavy metals was better at stronger acidic condition. The conductivity of the soil sample treated with lime water increased with the increase of the concentration of organic acid,and at the same concentration,the conductivity was in the order of citric acid > acetic acid. | Bing YU Mingxin MEN Peijia LIU Kening WU | 2019 | Agricultural Biotechnology2019,8,1: | 3 |
| 12 | Combined effects of interface modification and micro-filler reinforcements on the thermal and tribological performances of fabric composites显示文摘The high specific‐strength of glass fibers and exceptional self‐lubrication of polytetrafluoroethylene(PTFE)fibers promote the potential application of hybrid PTFE/glass fabric composites in the tribological field,but their weak interfacial adhesion and inferior thermal properties significantly inhibit their tribological performance and reliability.Herein,a hybrid of polydopamine/silicon carbide/polyethyleneimine(PDA/SiC/PEI)functional coating was co‐deposited onto the hybrid PTFE/glass fabric surface through a one‐step impregnation method,leading to increased surface roughness and abundant amine groups.Tensile and peeling tests showed that this functional coating offered 47.8%enhancement in the fabric/matrix interfacial adhesion without compromising the strength of the pristine fabric.Moreover,the additional incorporation of WS_(2),and aluminum nitride(AlN)micro‐fillers contributed to the development of a high‐quality tribofilm and improved the thermal properties of fabric composites.The results of wear tests proved that the hybrid‐fabric composites,after the introduction of functional coating and micro‐fillers,exhibited outstanding tribological performance,which was attributed to the superior interfacial adhesion as well as the synergistic enhancement effects between WS2 and AlN micro‐fillers. | Junya YUAN Zhaozhu ZHANG Mingming YANG Xin ZHAO Liangfei WU Peilong LI Wei JIANG Xuehu MEN Weimin LIU | 2021 | Friction2021,9,5: | 3 |
| 13 | Fabrication of PTFE/Nomex fabric/phenolic composites using a layer-by-layer self-assembly method for tribology field application显示文摘Fabric composites are widely applied as self-lubricating liner for radial spherical plain bearings owing to their excellent mechanical and tribological properties.Nevertheless,the poor interfacial strength between fibers and the resin matrix limits the performance of composites utilized as tribomaterials.To overcome this drawback,a mild layer-by-layer(LbL)self-assembly method was successfully used to construct hybrid fabric composites in the present work.In addition,this investigation addressed the effect of self-assembly cycles on the friction and wear behaviors of hybrid fabric composites under dry sliding condition.The results demonstrate that fabric composites with three or more self-assembly cycles have significantly enhanced surface activities and anti-wear performances.The results obtained in this work can provide guidance in the preparation of self-lubricating liner composites and highlight how the LbL self-assembly techniques could influence the properties of hybrid fabric composites. | Mingming YANG Zhaozhu ZHANG Junya YUAN Liangfei WU Xin ZHAO Fang GUO Xuehu MEN Weimin LIU | 2020 | Friction2020,8,2: | 3 |
| 14 | Revisiting the effects of Co_(2)O_(3)on multiscale defect structures and relevant electrical properties in ZnO varistors显示文摘Element doping is an effective method to improve the performance of ZnO varistors.Previous studies mainly focused on the variation of microstructures and Schottky barriers.In this study,the effects of Co dopant on electrical properties are investigated from the aspect of multiscale defect structures,including intrinsic point defects,the heterogeneous interface of depletion/intergranular layers,and interface states at grain boundaries.Combining with analysis of phase composition and energy dispersive spectroscopy,it is found that Co tends to dissolve into ZnO grains when slightly doped.It substitutes Zn2+with the same valence and affects little on densities of donors.Segregation of Co at grain boundaries would result in the formation of spinel phase Co(Co4/3Sb2/3)O4 and transformation of the intergranular phase fromα-Bi2O3 toδ-Bi2O3.Meanwhile,densities of point defects are indirectly affected by oxygen ambient during sintering,resulting in abnormal variation of grain resistivity.And interface states are enhanced,leading to improved barriers at grain boundaries.Therefore,reduced leakage current,enhanced grain resistivity,and improved non-linear coefficient in Co-doped ZnO varistor blocks are understood from the underlying multiple defect structures.This presents a potential approach to explore short-term performance and long-term stability of ZnO varistors from the aspect of defect responses. | Men Guo Yao Wang Kangning Wu Lei Zhang Xia Zhao Ying Lin Jianying Li | 2020 | High Voltage2020,5,3: | 2 |
