Ping Feng,Xiao-li Wang,Chao Zhang,Wei Sun,Dai-min Chen 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.12
According to the mechanism of EMG signal, we know that the sacrificial electrical signal is with weak signal, low frequency, alternating, nonlinear and non-stationary characteristics. Nonlinear analysis includes higher order spectral analysis and fractal and chaos analysis.Chaos theory is one of the main parts of nonlinear science, and the electrical signal of the surface has a strong randomness, so we could consider the nonlinear analysis of EMG signals from the perspective of chaos. We mainly studied on the nonlinear analysis algorithm of EMG signal detailedly in this paper. Experiments show that,according to the quantitative analysis of several important parameters of rolling massage with chaos theory, we can measure objectively the action situation of related muscle groups in the operation course, then guide the professional massage students to understand the norms of operation in training of operation and help to lead their manipulation to the best power structure.

Performance capability of emergency management refers to the actual performance of the emergency management of an organization, individual or region. The improvement of the government's emergency management capacity is of great significance to the effective response of a country or local emergency. Performance capability evaluation of emergency management for an organization, individual or region can reflect their capability of emergency management, so as to help them make a more clear and comprehensive judgment to the ability of emergency response, enhance the ability of emergency response, promote China’s emergency response capability and reduce the loss of life and property caused by emergency. The report of Evaluation of performance capability for emergency management in 31 provinces of China in 2014-2015 is jointly issued by Public Management Professional Committee in Society of Management Science of China, Ouhua’ antai Risk and Crisis Emergency Research Institute, Emergency Management Institute of Henan Polytechnic University in 21th January, 2016. In the report, firstly, the 10 worst disaster incidents of each province in 2014-2015 are selected, and then every index of the accidents is graded through being analyzed with consulting American evaluation index system for emergency management and the reaction of the different kinds of accidents. At last, the weighted averages of the indexes are worked out. Meanwhile, the performance capability for emergency management in 31 provinces of China in 2014-2015, including precautions, responses and aftermath, is evaluated qualitatively and quantitatively from aspects of natural disasters, human disasters and comprehensive performance. Based on it, the relevant performance capability is ranked and classified according to four grades: excellent, good, medium and poor. The evaluation report shows that comprehensive performance of Beijing and other 5 provinces is excellent; comprehensive performance of Jiangxi and other 13 provinces is good; comprehensive performance of Chongqing and other 10 provinces is medium; comprehensive performance of Tianjin and some other provinces is poor. To sum up, the excellent evaluation depends on whether the reasonable measures have been taken and whether the better result have been seen; the good and medium evaluation implies that there is some situation discovered in those provinces, just like the worse results in several accidents and lack of risk consciousness; the others are evaluated for the poor performance capability because of their faults full from the precautions to the aftermath. The report also attracts some friends from domestic mainstream media, such as the Paper, Sohu, China News, Science Net and China Youth Online, who consider that the performance capability for emergency management of China’s provinces is cognized deeply and the feasible blueprint is drawn on improving capability for emergency management in China through the report.

Central limit theorem for weighted local time of $L^2$ modulus of fractional Brownian motion
Chen, Chao,Yan, Litan,Ju, Cheng 한국통계학회 2012 Journal of the Korean Statistical Society Vol.41 No.4
In this paper, we mainly prove a central limit theorem for weighted local time of $L^2$-modulus of fractional Brownian motion with Hurst parameter $H{\in}(\frac{1}{2},\;1)$. Similar to Hu and Nualart (2009), based on techniques of stochastic analysis, the main ingredients of the proof are analogous to the asymptotic version of Knight's theorem and the fractional Clark-Ocone formula for the $L^2$-modulus of the weighted local time increments.

Cathode material 0.5Li2MnO3·0.5LiNi0.5Mn0.5O2 is successfully synthesized by citrate acid assisted sol -gel method and shows pretty good electro-chemical performance. To elucidate the electro-chemical reactions and charge carrier transportation kinetics in the charge-discharge process, series of electrochemical impedance spectra for the first and the second charge process are measured on multiple given state of charges. The rapid augmentation of resistance to electronic conduction and ionic conduction within the voltage range 4.45-4.6 V where the removal of Li2O from Li2MnO3 component takes place gives us more evidence about the complicated “structurally integrated” feature of this material. The relatively large span of the arc responsible for electronic conduction and the extremely large Mn3+ related charge transfer resistance at the beginning of the second charging indicate that after one complete charge-discharge cycle, Li2MnO3 and LiNi0.5Mn0.5O2 domains still reserve its original structure and will keep its structure for the followed cycles.
Double-layer Fabry-P$\acute{e}$rot filter interferometric modulator display
Chen, Chao Ping,Xiong, Yuan,Yang, Yuxing,Li, Xiao,Li, Hongjing,He, Gufeng,Lu, Jiangang,Su, Yikai 한국정보디스플레이학회 2013 Journal of information display Vol.14 No.4
Presented is an interferometric modulator display characterized by double layers of liquid crystal (LC) Fabry-P$\acute{e}$rot filters. With this design, no polarizers and color filters are needed, and both the color and amplitude can be tuned by electrically controlling the LC's birefringence. Instead of the conventional RGB trisubpixel color scheme, a bisubpixel structure is proposed to render a super-wide color gamut. Through simulations, the device performance was numerically studied. The device was proven to be quite suitable for green-display application.

Purpose: Family with sequence similarity 83 member H (FAM83H) plays key roles in tumorigenesis. However, the specific rolesof FAM83H in cervical cancer (CC) have not been well studied. Materials and Methods: The RNA-seq data of 306 CC tissues and three normal samples downloaded from The Cancer GenomeAtlas were used to analyze the expression of FAM83H. The Kaplan-Meier method was used to draw survival curves. Associationsbetween FAM83H expression and clinicopathological factors were analyzed by chi-square test. Cox proportional hazards modelwas used to analyze prognostic factors. Loss-of-function assays were conducted to discover the biological functions of FAM83Hin cell proliferation, colony formation, invasion, and migration. Real-time Quantitative Reverse Transcription PCR (qRT-PCR)and Western blotting were used to measure the expression levels of FAM83H in CC cell lines. Results: Our results demonstrated that FAM83H is overexpressed in CC tissues and that high FAM83H expression is associatedwith worse overall survival (OS). High FAM83H expression in CC was associated with clinical stage, pathologic tumor, and pathologicnode. Univariate analysis suggested that FAM83H expression was significantly related to the OS of CC patients. Althoughmultivariate analysis showed that FAM83H expression was not an independent prognostic factor for the OS of CC patients, the effectsof FAM83H on CC cell growth and motility was significant. Loss-of-function experiments demonstrated that knockdown ofFAM83H inhibited proliferation, colony formation, migration, and invasion of CC cells by inactivating PI3K/AKT pathway. Conclusion: FAM83H might play a crucial role in CC progression and could act as a novel therapeutic target in CC.
Facial Expression Recognition Model Based on Computer Vision
Chen Chao,Huang Linlin 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.10
A new facial feature position self-calibration method based on active computer vision is proposed in this paper to realize facial expression recognition. Compared with traditional method, the proposed method based on the extension focus thought only needs four linearly independent translational movements, one real rotational movement and one virtual rotational movement rather than the calibration reference object to realize the linear solutions orderly for internal reference matrix of camera, hand-eye relationship and feature point target depth. The experiment result shows that the proposed method is feasible and effective and the measurement errors of two-dimensional and three-dimensional feature points can be below 0.40mm, thus able to meet the industrial accuracy requirements.
