Guowei Xu,Ruxia Zhou,Wei Liu,Fangrui Hao 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.7

In order to enhance the tension control performance of the carbon fiber multilayer diagonal loom, twocontrol methods based on the yarn warping and the curling control are proposed. The tension control mathematicalmodels of carbon fiber multilayer diagonal loom, the yarn warping control model and the curling control model, arereestablished by the force analysis of the warping and the curling systems. Some technological process movements,such as the opening and the beating-up, are regarded as the disturbances. Based on the equivalent sliding modecontrol theory, the tension control strategies of the warping and the curling are constructed. Lyapunov method isused to prove the stability of the systems. Simulation results show that both the two methods could control thetension of the yarn, and the control results have good robustness to the disturbances.

Guowei Zhao,Guangming Zhuang,Jianwei Xia,Wei Sun,Junsheng Zhao,Minsong Zhang 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.6

This paper is concerned with the problem of mode dependent H∞ filter for uncertainty Markovian jump system with neutral delay and retarded time-varying delay. By using free weight matrix (FWM) technique, the stability conditions of delay dependent are obtained under the framework of Lyapunov stability theory. Based on those result, the delay dependent conditions for full order and mode dependent Markovian jump linear filters are gained, which are expressed by Linear matrix inequalities (LMIs). Finally, a numerical example and a PEEC practical example are employed to prove the validity of the results.

Wei Liu,Shuo Wang,Fengdong Shi,Guowei Xu,Yi Cheng 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.3

In order to improve the control effect of the tension fluctuation, a single neuron adaptive control strategy based on quadratic performance index is proposed in this paper. The structure and the working principle of carbon fiber diagonal loom are studied which can be used for dynamic analysis and controller design. With the idea of optimal control, the parameters of the controller are adjusted by minimizing the sum of the square of the output error and the control increment. The simulation results based on TrueTime show that the strategy adopted in this paper compared with the traditional control strategy have the advantages of faster response time and smaller overshoot in networked control system.

Anak Agung Gede Dharma,Hiroyuki Kumamoto,Shogo Kochi,Natsuki Kudo,Guowei Wei,Shu Chuan Chiu,Kiyoshi Tomimatsu 한국멀티미디어학회 2011 한국멀티미디어학회 국제학술대회 Vol.2011 No.-

In this research, we propose an online service which utilizes Social Networking Service (SNS) as the medium and Japanese cartoon (manga) as the communication method. The growth of SNS has created a new potential in marketing. While users communicate and interact via SNS, the list of their conversation which is called casual data can be used to determine their needs or aspirations. SNS can be very useful for product/service developers, especially when developing new ideas or simply evaluating the feasibility of their existing products/services. Furthermore, SNS provides a unique system that enables expressive and two-way communication between its users. Although several online services that utilize SNS and casual data have been provided, the purpose of those services is still unclear and ineffective. To solve those problems we propose an innovative way of utilizing SNS and casual data in designing consumer generated design. In our proposed system, users can directly contribute to the product/service development process in an interesting way. We designed an online service which allows users to posts manga that describes their original idea. While contributing to the product/service development, they can also benefit from expressing their hobbies and receiving feedbacks from other users.

Femtosecond Photoelectron Imaging of N₂ at 410 nm

Guo, Wei,Wei, Shanshan,Lu, Xingqiang,Wang, Li Korean Chemical Society 2010 Bulletin of the Korean Chemical Society Vol.31 No.12

We experimentally measure the kinetic energy and angular distributions of photoelectrons of $N_2$ as a function of 410 nm femtosecond laser intensity by using velocity map imaging technique. The strong-field multiphoton ionization of molecules shares many of the characteristics with those of atoms. Electron kinetic energies are nearly independent of laser intensities. The independence suggests that the electron peaks in the photoelectron spectrum actually result from a two-step process, indicative of the occurrence of real population in the intermediate states. The relative amplitudes of electron peaks indicate that in the two-step process, nonresonant population transfer dominates for low intensities, while resonant population transfer dominates for higher intensities.

Guo, Wei,Jin, Xiao-Ju,Yu, Jun,Liu, Yang,Zhang, Jian-Ping,Yang, Da-Wei,Zhang, Lei,Guo, Jiang-Rong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21

Objective: To investigate the effects of stellate ganglion block (SGB) on the peri-operative vasomotor cytokine content and intrapulmonary shunt in patients with esophagus cancer who underwent thoracotomy. Materials and Methods: Forty patients undergoing elective resection of esophageal cancer patients who had I~II American Society of Anesthesiologist (ASA) were randomly divided into total intravenous anesthesia group (group N, n=20) and total intravenous anesthesia combined with SGB group (group S, n=20, 0.12 mL/kg 1% lidocaine was used for SGB 10 min before induction). Heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), mean pulmonary arterial pressure (MPAP) and continuous cardiac output (CCO) were continuously monitored. The blood from internal jugular vein was drawn respectively before induction ($T_0$), and 30 min ($T_1$), 60 min ($T_2$) and 120 min ($T_3$) after one-lung ventilation (OLV), and 30 min (T4) after two-lung ventilation. The contents of plasma endothelin (ET), nitric oxide (NO) and calcitonin gene-related peptide (CGRP) were detected with enzyme linked immunosorbent assay (ELISA). Meanwhile, arterial and mixed venous blood samples were collected for determination of blood gas and calculation of intrapulmonary shunt fraction (Qs/Qt). Results: During OLV, ET contents were increased significantly in two groups (P<0.05), and no significant difference was presented (P>0.05). NO content in group S was obviously higher than in group N at T3 (P<0.05), whereas CGRP content in group N was markedly lower than in group S at each time point (P<0.05). Qs/Qt was significantly increased in both groups after OLV, but there was no statistical significant regarding the Qs/Qt at each time point between two groups. Conclusions: Total intravenous anesthesia combined with SGB is conducive to regulation of perioperative vasomotor cytokines in thoracotomy, and has little effect on intrapulmonary shunt at the time of OLV.

Guo, Wei,Li, Guo-Jun,Xu, Hong-Bo,Xie, Jie-Shi,Shi, Tai-Ping,Zhang, Sheng-Zhong,Chen, Xiao-Hong,Huang, Zhi-Gang Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.8

Background: Novel prognostic biomarkers or therapeutic molecular targets for laryngeal squamous cell carcinoma (LSCC) are an urgent priority. We here sought to identify multiple novel LSCC-associated genes. Methods: Using high-density microarray expression profiling, we identified multiple genes that were significantly altered between human LSCCs and paired normal tissues. Potential oncogenic functions of one such gene, DCUN1D5, were further characterized in vitro. Results: Our results demonstrated that DCUN1D5 was highly expressed in LSCCs. Overexpression of DCUN1D5 in vitro resulted in 2.7-fold increased cellular migration, 67.5% increased invasive capacity, and 2.6-fold increased proliferation. Endogenous DCUN1D5 expression was decreased in a time-dependent manner after genotoxic stress, and silencing of DCUN1D5 by siRNA decreased the number of cells in the S phase by 10.2% and increased apoptosis by 11.7%. Conclusion: Our data suggest that DCUN1D5 in vitro might have vital roles in DNA damage response, but further studies are warranted to assess its significance in vivo.
