A tubular interface crack in a hollow composite cylinder is analyzed under static torsion. For four frequently encountered constraintedges--free-free, clamped-clamped, free-clamped, or clamped-free edges--theoretical derivation is performed by the Fourier integraltransform method. The mixed boundary value problem associated with a mode-III interface crack for each case is reduced to a singularintegral equation, from which the numerical results of Stress intensity factors (SIFs) are obtained by the Lobatto-Chebyshev quadraturetechnique. Numerical results of SIFs show that a coupled effect exists of geometrical and physical parameters on the interfacial fracturebehavior, which clearly relates to the selecting of constraint edges.
A Survey on Markovian Jump Systems: Modeling and Design
Peng Shi,Fanbiao Li 제어·로봇·시스템학회 2015 International Journal of Control, Automation, and Vol.13 No.1
Markovian jump systems are a special class of hybrid and stochastic systems which can be used to describe many real world applications, such as manufacturing systems, power systems, chemical systems, economic systems, communication and control, etc. In this paper, a survey on recent developments of modeling, analysis and design of Markovian jump systems is presented. First, stability issues on Markovian jump systems are addressed. Then a variety of control and filter design methods are systematically recalled. Furthermore, the new trends of Markovian jump systems with uncertain transition rates as well as semi-Markovian jump systems are also discussed.
Observation of multi-channel non-local transport in J-TEXT plasmas
Shi, Yuejiang,Chen, Zhongyong,Yang, Zhoujun,Shi, Peng,Zhao, Kaijun,Diamond, Patrick H.,Kwon, JaeMin,Yan, Wei,Zhou, Hao,Pan, Xiaoming,Cheng, Zhifeng,Chen, Zhiping,Yang, SeongMoo,Zhang, Chi,Li, Da,Dong, IOP 2018 Nuclear fusion. Fusion nucléaire. &n.Illiga Vol.58 No.4
<P>In cold pulse experiments in J-TEXT, not only are rapid electron temperature increases in the core observed, but also steep rises in the inner density are found. Moreover, some evidence of acceleration of the core toroidal rotation is also observed during the non-local transport process of electron temperature. These new findings of cold pulse experiments in J-TEXT suggest that turbulence spreading is a possible mechanism for the non-local transport dynamics.</P>

The elastic stress field around a circular elastic inclusion in an infinite functionally graded material (FGM) panel that is subjected to auniform static anti-plane shear loading at infinity is considered. Assuming the rigidity modulus of the FGM panel to be exponential, theanalytical solutions of stress and strain distribution around the circular elastic inclusion are obtained by using the variable separationmethod. Due the generality of the elastic inclusion, other geometrical discontinuities, such as hole and rigid inclusion, can be seen asspecial cases of circular elastic inclusion when the inclusion rigidity modulus takes a suitable value. Therefore, the present solutions analyticallyreduce to some classical solution in some special cases. The present analytical solutions are compared with the existing exactsolutions to verify them. Finally, the effects of the relative inclusion rigidity modulus ratio and the inhomogeneous rigidity modulus ratioon the stress distribution and the concentration factor are systematically investigated.
Impact of stereotypes on intercultural communication: a Chinese perspective
Shi-Yong Peng 서울대학교 교육연구소 2010 Asia Pacific Education Review Vol.11 No.2
Using Kuhn and McPartland's approach, 116 Chinese college students were recruited and asked to write as many sentences as possible beginning with "Chinese...,'' "Americans...,'' and "Japanese....'' The population of sentences consisted of 258 adjectives, of which 96 described Chinese, 53 described Americans, and 109 described Japanese. Next, the first ten adjectives with the highest frequencies describing Chinese, Americans, and Japanese, respectively were selected for the second step of data collection in that students were asked if they would accept these adjectives describing Chinese, Americans, and Japanese. If they did, they were further asked to provide examples or illustrations to support their agreement. Based on the top 30 adjectives and the qualitative data collected at the second step, students' perceptions of Chinese, American, and Japanese were analyzed. The results of the data analysis discovered that Chinese students are, to some extent, stereotyped toward American and Japanese, and their understanding of Chinese people is not accurate, either. The results confirm that media to certain extent are responsible for the shaping of some of the students' stereotypes. Evidently, the results of this study suggest that the Chinese students' stereotypes will affect their intercultural communication with Americans and Japanese. Although this study does not provide tactics on the reduction or elimination of stereotypes in the process of intercultural communication, it provides meaningful clues for future research in how stereotypes may be reduced by way of intercultural contact or training. This research has two major limitations. First, all the subjects are Chinese. Had American and Japanese samples been selected for a comparative investigation, more meaningful and insightful results could have been obtained. Second, because of the space constraints, verbs and nouns were not analyzed.

This study examined the relations between body composition and phys-ical fitness, targeting 17 middle school girls with dance major. In the body composition, the group of skilled showed significantly high fat free mass. In the physical fitness, the group of skilled significantly high muscular strength and flexibility. In the correlations, the weight, BMI, and fat free mass of body composition showed the significantly pos-itive correlations with muscular strength and their influence were 52.9%, 36.7%, 64.5% respectively. The body fat percentage showed the negative correlations with quickness and cardiorespiratory endurance and their in-fluences were 31.4% and 29.2% respectively.
Coordination between REDD + mechanism and legal system of China's forests
Yan Shi peng 원광대학교 법학연구소 2015 圓光法學 Vol.31 No.2
According to the Fourth Assessment Report of IPCC, deforestation accounts for 17.4 percent of global carbon emissions. The international community has become increasingly concerned about carbon emissions caused by forest degradation and deforestation, and REDD mechanism was also born in this context .On the basis of REDD mechanism, REDD + mechanism increased forest conservation, sustainable forest management and the content of forest carbon stocks, to make the mechanism apply in a more suitable space. As the most important measures to reduce emissions in post-Kyoto era forestry, REDD + mechanism has no more been questioned. China, as a developing country, is very fruitful in terms of forest protection. In order to ensure the implementation of REDD + mechanism in our country, we must integrate, improve and coordinate on the domestic legal system of forest to secure more funding of REDD + mechanism and ensure our initiative in the international climate negotiations.
