1Dynamic feedback robust stabilization of nonholonomic mobile robots based on visual servoing显示文摘This paper investigates the visual servoing robust stabilization of nonholonomic mobile robots. The calibration of visual parameters is not only complicated, but also needs great consumption of calculated time so that the accurate calibration is impossible in some situations for high requirement of real timing. Hence, it is interesting and important to consider the design of stabilizing controllers for nonholonomic kinematic systems with uncalibrated visual parameters. A novel uncertain model of these nonholonomic kinematic systems is proposed. Based on this model, a stabilizing controller is discussed by using dynamic feedback and two-step techniques. The proposed robust controller makes the mobile robot image pose and the orientation converge to the desired configuration despite the lack of depth information and the lack of precise visual parameters. The stability of the closed loop system is rigorously proved. The simulation is given to show the effectiveness of the presented controllers.Chaoli WANG 1 , Zhenying LIANG 2 , 3 , Qingwei JIA 4 (1.Department of Control Science and Engineering, University of Shanghai for Science and Technology, Shanghai 200093, China 2.Business School, University of Shanghai for Science and Technology, Shanghai 200093, China 3.School of Science, Shandong University of Technology, Zibo Shandong 255049, China 4.Research & Development Centre, Hitachi Asia Ltd, Hitachi Tower, Singapore 049318) 2010控制理论与应用(英文版)2010,8,2:13
2Molecular adsorbent recycling system in treat-ing patients with acute liver failure: a bridge to liver transplantation显示文摘BACKGROUND:Acute liver failure is still a life-threaten- ing disease although it can be treated by liver transplanta- tion. This study was conducted to assess the molecular ad- sorbent recycling system (MARS), which may bridge acute liver failure patients to liver transplantation. METHODS: Biochemical indexes and other clinical data were analyzed of 8 patients with acute liver failure, who had been treated by MARS for 34 times and subsequent Piggyback liver transplantation. RESULTS: After treatment with MARS, the levels of tran- saminase and total bilirubin decreased markedly, but coagu- lation function remained unimproved. All patients survived and discharged from the hospital. CONCLUSION: MARS is effective in bridging patients with acute liver failure to liver transplantation.Yi-Tao Ding, Qing-Xiang Xu, Yu-Dong Qiu and Yi-Jun Yang Nanjing, China Department of Hepatobiliary Surgery, Affiliated Drum Tower Hospital of Medical College of Nanjing University Hepatobiliary In- stitute of Nanjing University Hepatobiliary Surgery Institute of Nanjing, Nanjing 210000, China 2004Hepatobiliary & Pancreatic Diseases International2004,3,4:5

4Non-bleeding technique in resection of hepatoma: report of 49cases显示文摘Objective: To investigate the experience and some re-lated problems of non-bleeding technique in partialhepatectomy.Methods: 49 cases of hepatic tumors were reviewed,including 41cases of hepatic carcinoma, 3 cases of sec-ondary hepatic carcinoma, 4 cases of haemangioma,and 1 case of hepatic adenoma. Three kinds of bleed-ing control technique including normothermic com-plete hepatic vascular exclusion (47/49), completevascular isolation with hypothermic perfusion (1/49),and partial extracorporeal hepatectomy (1/49) wereemployed.Results: The intraoperative volume of blood loss was1560±1252ml, and operative duration was 4.7±0.8h. One case died perioperatively because of severebleeding. 31 cases of primary hepatic carcinoma werefollowed up; the 0.5-, 1-, and 5-year survival rateswere 77% (24/31), 55% (17/31), and 36% (11/31)respectively.Conclusions: In liver surgery concerning hepatoma inthe segment of Couinaud Ⅰ, Ⅳ, Ⅴ or Ⅷ, Pringle’sprocedure is still the major method for bleeding con-trol. When the vena cava or/and venae hepaticaewas/were implicated, normothermic complete hepaticvascular exclusion is helpful. The partial extracorpo-real technique can provide a good exposure to the ca-va inferior, and is an alternative to the complete ex-tracorporeal method. Intraoperative B ultrasound de-tection plays an important role in choosing bleedingcontrol technique.Yi-Tao Ding Xi-Tai Sun Qing-Xiang Xu From the Department of the Hepatobiliary Surgery, Drum Tower Hospital, Medical School, Nanjing University 210008, China 2002Hepatobiliary & Pancreatic Diseases International2002,1,1:3
5TOF-SIMS analysis: Application to ultra-thin AWA film on magnetic head显示文摘F-containing polymer was coated on the magnetic head of hard disc drive (HDD) as theultra-thin (<20(?)) film of anti-wetting agent (AWA). A static TOF-SIMS method has been applied tomeasuring the thickness and coating uniformity of the ultra-thin film. TOF- SIMS is also used tostudy the micro-tribology and transfer of lubricant between the magnetic head and media interface.JIANG Zhicheng LIU Yiwei, Wah-Fuk Chung Chi-Yue Cheung Ichiro Yagi TIAN Hong Surface Analysis Laboratory, SAE Magnetics (H.
