| 1 | FREQUENCY OVERLAPPED SIGNAL IDENTIFICATION USING BLIND SOURCE SEPARATION显示文摘主要部件分析(PCA ) 和独立部件分析(集成通信适配器) 的概念,原则和用法被解释。然后算法和方法论基于 ofICA 的瞎的来源分离(BSS ) ,在哪个基于 PCA 预先增白因为观察信号被使用,被研究。瞄准混合发信号,部件其频率被对方重叠, BSS 的模拟由使用 BSS 的理论和途径发信号分开这类混合被做了。结果证明 BSS 有频率分析的传统的方法论没有的一些优点。 | WANG Junfeng SHI Tielin HE Lingsong YANG Shuzi | 2006 | Chinese Journal of Mechanical Engineering2006，19，2： | 6 |
| 2 | Study on the migration of nerve stem cell in vitro Induced by glioma cells显示文摘Objective: Previous studies have shown that glioma cells induced the migration of nerve stem cells (NSCs) in vivo. This study was exploring whether this situation could happen in vitro. Methods: Supernatant from C6 glioma cell lines or astrocytes cultured in serum-free medium growing in logarithmic phase were separately placed in lower chambers and NSCs were placed in the upper chambers of Trans-well culture system. After 36 h co-incubation, these NSCs spheres occurred on the middle membrane were counted. Results: Results demonstrated that the supernatant from C6 glioma cell culture, not from the astrocytes, enhanced the migration of NSCs (P<0.01). Conclusion: Some components in C6 glioma cell culture can attract the migration of NSCs. | Yilu Gao Shuzi Gao Yi Fen Sheyu Lin Mei Liu | 2005 | Journal of Nanjing Medical University2005，19，6： | 2 |
| 3 | Surface-Modified Graphene Oxide/Lead Sulfide Hybrid Film-Forming Ink for High-Efficiency Bulk Nano-Heterojunction Colloidal Quantum Dot Solar Cells显示文摘Solution-processed colloidal quantum dot solar cells(CQDSCs) is a promising candidate for new generation solar cells.To obtain stable and high performance lead sulfide(PbS)-based CQDSCs,high carrier mobility and low non-radiative recombination center density in the PbS CQDs active layer are required.In order to effectively improve the carrier mobility in PbS CQDs layer of CQDSCs,butylamine(BTA)-modified graphene oxide(BTA@GO) is first utilized in PbS-PbX2(X=I-,Br-) CQDs ink to deposit the active layer of CQDSCs through one-step spin-coating method.Such surface treatment of GO dramatically upholds the intrinsic superior hole transfer peculiarity of GO and attenuates the hydrophilicity of GO in order to allow for its good dispersibility in ink solvent.The introduction of B TA@GO in CQDs layer can build up a bulk nano-heterojunction architecture,which provides a smooth charge carrier transport channel in turn improves the carrier mobility and conductivity,extends the carriers lifetime and reduces the trap density of PbS-PbX2 CQDs film.Finally,the BTA@GO/PbS-PbX2 hybrid CQDs film-based relatively large-area(0.35 cm2) CQDSCs shows a champion power conversion efficiency of 11.7% which is increased by 23.1% compared with the control device. | Yaohong Zhang Guohua Wu Chao Ding Feng Liu Dong Liu Taizo Masuda Kenji Yoshino Shuzi Hayase Ruixiang Wang Qing Shen | 2020 | Nano-Micro Letters2020，12，9： | 2 |
| 4 | DISTRIBUTED MONITORING SYSTEM RELIABILITY ESTIMATION WITH CONSIDERATION OF STATISTICAL UNCERTAINTY显示文摘Taking into account the whole system structure and the component reliability estimation uncertainty, a system reliability estimation method based on probability and statistical theory for distributed monitoring systems is presented. The variance and confidence intervals of the system reliability estimation are obtained by expressing system reliability as a linear sum of products of higher order moments of component reliability estimates when the number of component or system survivals obeys binomial distribution. The eigenfunction of binomial distribution is used to determine the moments of component reliability estimates, and a symbolic matrix which can facilitate the search of explicit system reliability estimates is proposed. Furthermore, a case of application is used to illustrate the procedure, and with the help of this example, various issues such as the applicability of this estimation model, and measures to improve system reliability of monitoring systems are discussed. | Yi Pengxing Yang Shuzi Du Runsheng Wu Bo Liu Shiyuan | 2005 | Chinese Journal of Mechanical Engineering2005，18，4： | 2 |

| 8 | Dynamic Stiffness Deterioration of a Machining Center Based on Relative Excitation Method显示文摘The tool point frequency response function(FRF) is commonly obtained by impacting test or semi-analytical techniques.Regardless of the approach,it is assumed that the workpiece system is rigid.The assumption is valid in common machining,but it doesn't work well in the cutting processes of thin-wall products.In order to solve the problem,a multi-degree-of-freedom dynamic model is employed to obtain the relative dynamic stiffness between the cutting tool and the workpiece system.The relative direct and cross FRFs between the cutting tool and workpiece system are achieved by relative excitation experiment,and compared with the tool point FRFs at x and y axial direction.The comparison results indicate that the relative excitation method could be used to obtain the relative dynamic compliance of machine-tool-workpiece system more actually and precisely.Based on the more precise relative FRFs,four evaluation criterions of dynamic stiffness are proposed,and the variation trend curves of these criterions during the last six months are achieved and analyzed.The analysis results show that the lowest natural frequency,the maximum and the average dynamic compliances at x axial direction deteriorate more quickly than that at y axial direction.Therefore,the main cutting direction and the large-size direction of workpieces should be arranged at y axial direction to slow down the deterioration of the dynamic stiffness of machining centers.The compliance of workpiece system is considered,which can help master the deterioration rules of the dynamic stiffness of machining centers,and enhance the reliability of machine centers and the consistency of machining processes. | WANG Erhua WU Bo HU Youmin YANG Shuzi CHENG Yao | 2013 | Chinese Journal of Mechanical Engineering2013，26，5： | 1 |
