Portuguese_languageSichuan International Studies University is a public university located in Chongqing, China. It is colloquially known in Chinese as Chuan Wai . Originally founded as Russian Training School of Southwest Military University of PLA in May 1950, it is the only university specialized in foreign language studies in the Southwest region of China. Due to its close relationship with Ministry of Foreign Affairs, it is one of the few direct recruitment spots of Ministry of Foreign Affairs of People's Republic of China. The total student body amounts to 11,000, including foreign students and short-term students. According to the latest Wu Shulian Chinese Universities Rankings, Sichuan International Studies University is ranked No. 4 among all Chinese international studies universities. Sichuan International Studies University is an important base for foreign language education and scientific research and information consultancy center in the southwest as well. Over the past six decades, plenty of foreign language teaching and research talents have gathered here in the university, we have accumulated rich experience in foreign language teaching, made remarkable achievements in foreign language research, built advanced philosophy for foreign language teaching, created good environment for foreign language learning, and deposited profound cultural heritage on the campus.Foreign languages offered in the college include Portuguese language / Portuguese, Russian, English, Spanish, French, Italian, German, Korean, Japanese and Arabic . A number of non-language specialties have been added to its curriculum, such as law, journalism, Chinese as a foreign language, advertising, and tourism management. Six master degree programs have been offered, namely, Portuguese, Russian Language and Literature, English Language and Literature, French Language and Literature, German Language and Literature, Japanese Language and Literature, Comparative Literature and World Literature.

For the fusion problem of the multifocus images of the same scene, a novel scheme is proposed based on lifting stationary wavelet transform (LSWT) and a new m-channel pulse coupled neural network (PCNN). By using LSWT, we can calculate a flexible multiscale and shift-invariant representation of registered images. In order to overcome the shortcoming of PCNN which is not convenient and economical for a real system, a new m-channel PCNN is proposed and used to fuse the subband coefficients of LSWT. For choosing the low frequency subband coefficients, we take energy of Laplacian of image, which can effectively represent the salient features and sharp boundaries of image in LSWT domain, as input to motivate the m-channel PCNN. When choosing the bandpass subband coefficients, the local neighborhood sum of Laplacian (LNSL) measurement is introduced and taken as external stimulus to motivate the m-channel PCNN. The algorithm has been used to merge several sets of multi-focus images; both visual and quantitative analysis show that, comparing with conventional image fusion algorithms, the proposed approach can provide a more satisfactory fusion outcome. © 2011 by Binary Information Press.

In research of TESOL, the most important issue is how to determine the course content scientifically and how to solve students' problems accurately, and the existing researches have not provided effective solutions yet, therefore the Ontology Technology-supported English Teaching Scheme has been proposed, in which ontology-based problem detection and resource recommendation method has been used to fulfill this goal. Finally, the results of the application experiment have verified the feasibility and superiority of the proposed scheme. © 2013 Springer-Verlag Berlin Heidelberg.

Due to the short duration of impulsive impact of an aircraft during touchdown, a traditional landing gear can only achieve limited performance. In this study, a magnetorheological (MR) absorber is incorporated into a landing gear system; an intelligent control algorithm, a human simulated intelligent control (HSIC), is proposed to adaptively tune the MR absorber. First, a two degree-of-freedom (DOF) dynamic model of a landing gear system featuring an MR absorber is constructed. The control model of an MR damper is also developed. After analyzing the impact characteristic during touchdown, an HSIC is then formulated. A genetic algorithm is adopted to optimize the control parameters of HSIC. Finally, a numerical simulation is performed to validate the proposed damper and the controller considering the varieties of sink velocities and sprung masses. The simulations under different scenarios show that the landing gear system based on the MR absorber can greatly reduce the peak impact load of sprung mass within the stroke. The biggest improvement of the proposed controller is over 40% compared to that of skyhook controller. Furthermore, HSIC exhibits better adaptive ability and strong robustness than skyhook controller under various payloads and sink velocities. © 2013 X. M. Dong and G. W. Xiong.

This paper employs the evolutionary game theory to analyze the cooperation between microgrid and conventional grid, with the discussion focusing on the factors that influence the game players' selection of strategies, and additionally makes a numerical simulation analysis. The results of analysis based on the evolutionary game model suggest that the two parties' undertaking of cooperative strategies and uncooperative strategies during the game is the stable point of their evolution and that the probability of their unanimous choice of cooperative strategies positively correlates with the direct benefits and indirect benefits of their cooperation as well as the government subsidies but negatively correlates with the cooperation costs and spending on cooperation risks. Based on the findings, the paper puts forward a series of policy suggestions aiming to deepen the cooperation between microgrid and conventional grid. Copyright © 2015 C. Pan and Y. Long.

Analyzing carbon emissions is critical for successfully managing sustainable production and consumption. In a dual channel supply chain that includes traditional retailers and online e-tailers, consumer free riding often occurs when consumers enjoy the services provided by a traditional retailer but make purchases at a lower price from an e-tailer. The specific aim of this paper, therefore, is to evaluate the impact of consumer free riding on carbon emissions in a product's life cycle across a dual channel closed loop supply chain and to assess the effect of governmental e-commerce tax on carbon emissions. The study comprises a systematic comparison and numerical analysis of cases in which consumers do or do not free ride. Our results show that although manufacturers may gain economic benefits from consumer free riding behavior, total carbon emissions across the supply chain increase too, and a governmental tax on e-commerce can help reduce consumer free riding and total carbon emissions. Our research also suggests that, a government may have to subsidize the e-tailer in the consideration of maximizing the social welfare. © 2016 Elsevier Ltd.
