Study on Effect of Massage Technique based on Chaos Theory
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.
Evaluation of Performance Capability for Emergency Management in 31 Provinces of China in 2014-2015
An Chen,Chao Fan 위기관리 이론과 실천 2016 위기관리 이론과 실천 학술대회 Vol.2016 No.08
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.

Nighttime Fire Smoke Detection System Based on Machine Vision
Chao-Ching Ho,Ming-Chen Chen 한국정밀공학회 2012 International Journal of Precision Engineering and Vol. No.
A real-time machine vision–based nighttime fire smoke detection method that can be incorporated into a surveillance system for early fire alert is proposed in this paper. Nowadays, video surveillance–based early fire smoke detection is crucial to the prevention of large fires and the protection of life and goods. However, many of the known video smoke detection methods require that minimum illumination be provided for the cameras to recognize the existence of fire smoke in a scene. To overcome the nighttime limitations of video smoke detection methods, a laser light is projected into the monitored field of view, and the returning projected light section image is analyzed in order to fire smoke. If the fire smoke appears within the monitoring zone created from the diffusing or scattering projected light path, the camera sensor receives a corresponding signal. The successive processing steps of proposed real-time algorithm are using the spectral, diffusing, and scattering characteristics of the fire smoke regions in the image sequences to register the possible smoke position in a video. Characterization of smoke is carried out by calculating accumulative deviation from the extracted feature vectors, and a classification method using a fuzzy reasoning system is applied to assign a score to the potential fire smoke candidate. Experimental results in a variety of nighttime conditions demonstrate that the proposed fire smoke detection method can successfully and reliably detect fire smoke.

Surface Texture of Pulse-magnetron-sputtered ZnO:Al Films by Using a Diluted NH4Cl Aqueous Solution
Chao Chen,Yan Liang,Xiao-Yong Gao 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.66 No.10
This paper mainly addresses the effects of the NH4Cl concentration and etching time on the surface texture of <103>-oriented ZnO:Al films deposited by using direct-current pulse-magnetron reactive sputtering. A mechanism for the etching of the ZnO:Al films by NH4Cl is also proposed. The best surface texture was observed the same as it was etched for 15 min by using a 3.0 wt.% NH4Cl solution. The average reflectivity at wavelengths from 300 nm to 800 nm was sharply reduced to 4.607%. The etching with NH4Cl is closely related to the preferential <103> orientation rather than the usual preferential <002> orientation. The increased number of defects around the boundary is responsible for the surface texture and the blueshift of the absorption edge of the films.
User Identification Design by Fusion of Face Recognition and Speaker Recognition
Chao-Yu Lin,Kai-Tai Song,Yi-Wen Chen,Shuo-Cheng Chien,Sin-Horng Chen,Chen-Yu Chiang,Jyh-Her Yang,Yi-Chiao Wu,Tzu-Jui Liu 제어로봇시스템학회 2012 제어로봇시스템학회 국제학술대회 논문집 Vol.2012 No.10
Intelligent human-robot interface helps a mobile robot to extract external information and interact with a user. User identification information allows a robot to generate appropriate behaviors and make personalized human-robot interaction (PHRI) more natural and safe. Most of service robots move around in various application settings, and biometric features always change during relative movements. In this work, a fusion recognition system based on face and speaker classifiers is designed to achieve the user recognition in various environments. We propose a method to fuse face and speech recognition results based on the concept of confidence indices. Through the derived confidence indices, the system combines the two classifiers and gives improved recognition results. Experiments on a laboratory home service robot show that person recognition rates in 15 environmental situations all outperform those of using single modality.
Monoview/dual-view switchable liquid crystal display.
Chen, Chao Ping,Lee, Joong Ha,Yoon, Tae-Hoon,Kim, Jae Chang Optical Society of America 2009 Optics letters Vol.34 No.14
<P>We present an optical device capable of displaying in two distinct viewing modes, i.e., monoview and dual-view modes. The monoview mode has a joint viewing cone and allows only the same image or video content to be displayed. The dual-view mode splits one viewing cone into two so that two different pieces of information can be displayed simultaneously in the left and the right viewing directions from the screen. Each viewing mode can be mutually switched through the modulation of the birefringence of liquid crystals. This proposed device has technical advantages of easy operation, low cost, and versatility of applications.</P>
