| 1 | Gearbox Deterioration Detection under Steady State,Variable Load, and Variable Speed Conditions显示文摘Multiple dominant gear meshing frequencies are present in the vibration signals collected from gearboxes and the conventional spiky features that represent initial gear fault conditions are usually difficult to detect. In order to solve this problem, we propose a new gearbox deterioration detection technique based on autoregressive modeling and hypothesis testing in this paper. A stationary autoregressive model was built by using a normal vibration signal from each shaft. The established autoregressive model was then applied to process fault signals from each shaft of a two-stage gearbox. What this paper investigated is a combined technique which unites a time-varying autoregressive model and a two sample Kolmogorov-Smirnov goodness-of-fit test, to detect the deterioration of gearing system with simultaneously variable shaft speed and variable load. The time-varying autoregressive model residuals representing both healthy and faulty gear conditions were compared with the original healthy time-synchronous average signals. Compared with the traditional kurtosis statistic, this technique for gearbox deterioration detection has shown significant advantages in highlighting the presence of incipient gear fault in all different speed shafts involved in the meshing motion under variable conditions. | SHAO Yimin CHRIS K Mechefske OU Jiafu HU Yumei | 2009 | Chinese Journal of Mechanical Engineering2009，22，2： | 6 |
| 2 | 机器人辅助腹腔镜根治前列腺切除术的外科学习曲线:一名外科医生500病例的经验显示文摘本文分析了机器人辅助腹腔镜根治前列腺切除术(RALP)初期250例和后期250例患者。500位连续接受RALP的临床局部前列腺癌患者分为第Ⅰ组:第1-250案(2006年12月-2010年12月)和第Ⅱ组:第251-500案(2011年1月-2012年12月)。记录两组的临床特点,比较两组的操作参数和手术期并发症。评估病理结果、肿瘤细胞残留手术组织边缘和生化复发率(BCR)。我们从每50个RALP案例中分析肿瘤细胞残留手术组织边缘fPSM)和神经血管束(NVB)保留,局部肿瘤的复发风险和病理分期的关系。第Ⅱ组比第1组有更多的晚期前列腺癌(切片检查格里森分数8—10,P=0.033:临床分期T3,P=0.叭7),并呈现显著性差异。控制台时间和失血从第Ⅰ组到第Ⅱ组大幅下降(控制台时间为165.16±53.51min vs 103.37±22.04min;失血为174.56±201.32ml vs 99.80±104.77m1)。输血在第1组减少3.2%(8/250)vs第Ⅱ组减少1.2%(3/250)以及手术期并发症比率在第1组减少9.6%(24/250)VS第Ⅱ组减少5.6%(14/250)。pT3的肿瘤细胞残留手术组织边缘N49%(第1组)降到32.6%(第Ⅱ组)。每50个案例减少肿瘤细胞残留手术组织边缘(PSM)的重要趋势,包括pT3和高度危险。神经血管束(NVB)保留会严重影响高度危险患者的肿瘤细胞残留手术组织边缘(PSM)(84.1%NVB保留群vs 43.9%NVB保留群)。3年、5年和7年无BCR的幸存者分别为79.2%、75.3%和70.2%。T3的肿瘤细胞残留手术组织边缘自初期250个案例的49%大幅下降到随后250个的32.9%。每50个案例减少PSM的重要趋势,包括pT3和高度危险。因为PSM的增加,在RALP期间不建议对高度危险的前列腺癌进行神经血管束保留。 | Yen-Chuan OU Chun-Kuang Yang Kuangh-Si Chang John Wang Siu-Wan Hung Min-Che Tung Ashutosh K Tewari Vipul R Patel | 2014 | Asian Journal of Andrology2014，16，5： | 3 |
| 3 | Optimization of Mo/Cu(In,Ga)Se2/CdS/ZnO Hetero-Junction Solar Cell Performance by Numerical Simulation with SCAPS-1D显示文摘The paper presents a one-dimensional simulation study of chalcopyrite Cu(In,Ga)Se2(CIGS)solar cells,where the effects of the variation of CIGS,CdS,and ZnO layers are presented.Additionlly the influence of the variation of doping and the defects density of shallow uniform donors and acceptors types are also presented.The analyse of the simulation results shows that recombination inside the space charge region(SCR)decrease more our CIGS solar cell model performance.We also found that the electrical parameters increase with increasing CIGS absorber doping density exception of JSC values that reach their maximum at 1016cm-3 and decrease due to recombination of charge carriers in the p-n junction particularly the recombination inside the SCR.We also stressed the fact that the effects of shallow uniforme donor density is very low on the performance of our CIGS solar cell model is important because it will allow to control the width of space charge region from shallow uniform acceptors defect density that has a strong influence on the different electrical parameters.Yet,good optimization of performance of the CIGS-based solar cell necessarily passes though a good control of the space charge region width and will constitute a boosting perspective for the preparation of our next paper.We contact that the results obtained of the numerical simulation with SCAPS-1D show a good agreement comparatively of the literature results.The simulation of our CIGS solar cell presents best performances if the values of the absorber layer thickness is in the range of 0.02 to 0.03μm,the buffer layer thickness is in the range of 0.02 to 0.06μm and the defects density of shallow uniform acceptors types is in the range of 1015 to 1017cm-3. | Adama Zongo Daouda Oubda Soumaïla Ouédraogo Marcel Bawindsom Kébré Alain Diasso Issiaka Sankara Boureima Traore François Zougmoré Zacharie Koalga Frédéric Ouattara | 2021 | 材料科学与工程(中英文B版)2021，11，4： | 2 |
