Two Modified QUICK Schemes for Advection-Diffusion Equation of Pollutants on Unstructured Grids  [PDF]
Linghang XING
Journal of Water Resource and Protection (JWARP) , 2009, DOI: 10.4236/jwarp.2009.15043
Abstract: In this paper, two modified QUICK schemes, namely Q-QUICK and UQ-QUICK, for improving the preci-sion of convective flux approximation are verified in advection-diffusion equation of pollutants on unstruc-tured grids. The constructed auxiliary nodes for Q-QUICK/UQ-QUICK are composed of two neighboring nodes plus the next upwind node, the later node is generated from intersection of the line of current neighboring nodes and their corresponding interfaces. 2D unsteady advection-diffusion equation of pollut-ants is conducted for their verifications on unstructured grids. The numerical results show that Q-QUICK and UQ-QUICK have similar computational accuracy to the central difference scheme and similar numerical stability to upwind difference scheme after applying the deferred correction method. In addition, their corre-sponding CPU times are approximately equivalent to those of traditional difference schemes and their abili-ties for adapting high grid deformation are robust.
Practical Teaching Platform Construction Based on Moodle—Taking “Education Technology Project Practice” as an Example  [PDF]
Ruonan Xing
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.53B2113
Abstract:

Moodle platform is the international popular course management system. Based on the project practice of education technology course as an example, this article has set up a platform of experimental teaching based on Moodle platform. It mainly illustrates from the course management, self-regulated learning test,toprocedural evaluation and so on. This platform gives full express to the advantages of double main teaching model in which the teacher is dominant while students are the main body, and it has significance on reference to the practical and experimental curriculum.

Development and Design of Investigation Platform Based on the Mobile Media  [PDF]
Ruonan Xing
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.51B003
Abstract: Enterprise market research is mainly tend to the traditional paper investigation and telephone interview, The traditional survey method has wasted a lot of human material and financial resources, it also isn’t beneficial to statistical analysis and survey efficiency is low, so it brings a lot of inconvenience to the enterprise. This paper designs survey platform for the industry based on the analysis of the present Internet survey situation and with the help of the existing network platform characteristic. This platform uses the Ajaxand ASP. NET3.5 technology, it is suitable for online survey, voting, electing and testing. It reduces the burden of management and statistics work and improve the quality of the industry survey.
Application Research of DiGG in Teaching Platform  [PDF]
Ruonan Xing
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.49B003
Abstract:

As one member of web, Digg relies on its unique evaluation mechanism and provides a newly perspective to promote the development in network teaching. This article designs a teaching platform system based on the advantage of Digg and discusses the mechanism of Digg teaching.We need to arouse the subjective initiative of students and help them to utilize various resources for learning services effectively and improve the students’quality comprehensively.

Optimal Fiscal Policy Instrument under Different Shocks  [PDF]
Shuguang Xing
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.76115
Abstract: This paper constructs a New Keynesian model to study optimal tax and government spending rules and compares their welfare. The output gap, inflation and the difference between the output gap and the government spending gap all affect welfare. This paper finds that the optimal fiscal policy instruments under technical shock and cost-push shock are government spending and tax, respectively. If the policymaker is only concerned with the output gap and inflation, the optimal fiscal policy rule and actual social welfare loss will change. However, the optimal fiscal policy instruments under technical shock and cost-push shock are still government spending and tax. This paper also finds that an imperfect financial market affects social welfare but does not change the optimal fiscal policy instrument under different shocks.
The Literature Review of Raised Funds to Buy Financial Products  [PDF]
Xing Jiang
Journal of Financial Risk Management (JFRM) , 2018, DOI: 10.4236/jfrm.2018.71004
Abstract: Since 2015, the speed of A-share IPO review has been accelerating. The raised funds by listed companies hit record highs in many different ways. After the stock investment, investors have also begun to pay more attention to the whereabouts of the raised funds. Because of the phenomenon of frequent purchases of financial products by raised funds in the past three years, the academic community set off a wave of scholarship fund-raising academic research after 2000. This article discussed the existing literature theory on listed companies using raised funds to purchase trust financing. And this article not only gave a summary to the research methods and conclusions of the raised funds buying trust financing or financing products, but also reviewed the research about investment efficiency after the raised funds target project changed. At last, this paper gave several directions for the future study about raised funds.
Semantic Grammaticalization in the Construction “N1 you V guo N2” from Neo-Cognitive Pragmatic Perspective  [PDF]
Qiuhong Xing
Open Journal of Modern Linguistics (OJML) , 2018, DOI: 10.4236/ojml.2018.86019
Abstract: The construction “N1 you V guo N2” pervasively visible in China has demonstrated its typical cog-pragmatic features. It is pointed out that “you” and “guo” in this construction are the results of notional verbs’ grammaticalization. Grammatical features and cognitive motivation of it have been discussed based on the project theory and de-categorization theory. In its grammaticalization and pragmaticalization process the pragmatic markers contribute the most. Considering the integrated meaning from social, pragmatic and cognitive perspectives, it is found that the construction is out of the speaker’s particular intention, also the results of pragmaticalization.
Language Teaching Research Based on Applied Linguistics Theory  [PDF]
Huihui Xing
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.612029
Abstract: In order to study language teaching under applied linguistic theory, two definitions of applied linguistics, the breakthrough in the definition of applied linguistics, and the return of the core content to education and teaching, are introduced. The research results of language teaching under the theory of applied linguistics in recent years are listed. Taking English language teaching as an example and combining with applied language teaching theory, relevant teaching experiments are designed. According to the experimental results, it is concluded that applied linguistic teaching theory can effectively improve students’ interest in learning and enhance the effectiveness of language learning. Finally, it is concluded that applied linguistics theory should be based on language teaching, change the way of language teaching, and better transfer knowledge to students.
Characterization of Blood Flow in Capillaries by Numerical Simulation  [PDF]
Tong Wang, Zhongwen Xing
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.16049
Abstract: This paper presents a numerical investigation of the axisymmetric, pressure driven motion of single file erythrocyte (i.e., red blood cell) suspensions flowing in capillaries of diameter 8-11 µm. Our study success-fully recreates several important in vivo hemodynamic and hemorheological properties of microscopic blood flow, such as parachute shape of the cells, blunt velocity profile, and the Fahraeus effect, and they have been shown to have strong dependence on cell deformability, hematocrit and vessel size.
How Fast a Hydrogen Atom can Move Before Its Proton and Electron Fly Apart?  [PDF]
Wei-Xing Xu
Optics and Photonics Journal (OPJ) , 2011, DOI: 10.4236/opj.2011.12006
Abstract: In this paper we discussed the behavior of a hydrogen atom in moving and found there is a speed threshold for hydrogen atom. As long as the speed of hydrogen reaches or beyond its speed threshold, the proton and electron in hydrogen atom will fly apart. We also discussed the effect of the movement of hydrogen atom on its absorption spectrum which is important in spectrum analysis.
