Computer graphics has been applied for generating digital contents in many fields such as virtual/augmented reality, as well as traditional applications such as visual effects. However, serious mathematical background obstructs people from learning computer graphics. The proposed paper focuses on computer graphics for generating an effective e-learning platform. We utilized a block-based system, which is implemented by WebGL and delivers educational interests and enhanced accessibility. Also, users could practice the theory of graphics using processing language and check their programming result directly.

With computer-assisted instruction is widely used in university education, Multi-media teaching has produced a new form of education. Multimedia teaching has the effect of interactive and dynamic multi-dimensional, which enhances the students' learning interest and the understanding. In this paper, we make an empirical analysis about the impact of Wushu education on college students .The result shows that after using multimedia teaching, Wushu teaching can improve the physical function of college students, it will significantly improve the college students' sports view, sports value and sports motivation. At the same time, multimedia teaching can effectively improve the teaching quality. On this basis, we put forward relevant suggestions.

This paper presents the structure of an electronic attendance system composed of OAA (One-stop Attendance and Absence)-server and client. We compare simultaneous check, fraudulent attendance, prevention of leaving the classroom, and extra equipment according to check methods, and also present a method of app and web-based attendance management. NFC and BLE-based app and location-based web for attendance management were applied to classrooms. Issues with electronic attendance management and resolution methods were also presented. RESTful web service was defined for attendance management and performance analysis was conducted according to thread numbers of OAA-server and parser types of XML and JSON.

After 1990s, the rapid development of information technology bring multimedia computer into the classroom, multimedia technology has gradually become a teaching method of physical education. In this paper, we study the harmonious teaching method in women's aerobics education by using contrast experiment. Through the testing and evaluation of 57 female college students, the result shows that harmonious teaching method can greatly improve the technical movements of the body, improve the quality of sports and psychological quality. After the experiment, students have a significant improve in technical action aerobics exercise, motion effects, action convergence, combinations action, action novelty, accuracy and movement dynamics action have significant increase. On this basis, we put forward relevant suggestions.

This study aims to investigate the effect of promotion benefit level on consumers’ patronage intention in limited-quantity promotion (LQP) by considering the mediating influence of perceived availability. A mathematical model is built and an experiment is conducted to demonstrate that the effect of promotion benefit level on patronage intention is reversed U-shaped in LQP. When promotion benefit level is low, patronage intention increases as promotion benefit level increases, whereas when promotion benefit level is high, patronage intention would decrease as promotion benefit level increases. The mediating influence of perceived availability between promotion benefit level and patronage intention explains this phenomenon. Empirical results show that perceived availability is negatively related with promotion benefit level and patronage intention is positively related with perceived availability. Those results can be used by retailers to determine the most appropriate benefit level in LQP.

Recent years, as China is experiencing a rapid development, the educational investments are undergoing a sharp increase compared to past decades. Educational investment has become a crucial aspect that deeply influencing the future development of a country. What's more importantly, knowing the future investments of education is a crucial affair that decides the future tendency of related projects such as government management, cooperation investment and personnel training. Decision makers cannot make any effective decisions without knowing the future investments of education under all these circumstances. However, it is fairly difficult for people to obtain the predicted data of educational investments without the aid of mathematical and computational modeling. Therefore, in this article, we aim at presenting a series of solutions for the prediction of educational investment for China based on multiple linear regression (MLR), artificial neural networks (ANNs) and grey model GM (1,1). Multiple comparisons are made for deciding whether model should be used under different external conditions. Our research successfully shows that all these models are available for practical applications and scientists and other related people can choose their suitable models alternatively for the sake of making a better prediction under different circumstances.

The purpose of this research is to verify the effectiveness of the influence of an afterschool reading program on changing multicultural perception. The afterschool reading program at the elementary school is composed of 12sessions. The main content was reading a foreign fairy tale and then having a discussion on about it. The total number of subjects was 44 people, 21 in the experiment group and 23 people in the control group. Each group did a preliminary inspection before participating in the program, a post inspection after participating, and a later inspection 5 weeks after finishing the program. Research results showed that the reading-studying program improves the cognitive level of elementary school students’ multicultural perception. Moreover, the analysis results of multicultural awareness levels concerning the cognitive factors and defined factors seemed to be more effective than behavioral factors.

This paper builds the concept model of knowledge transfer based on analysis of characteristics and influencing factors in supply chain, and the system dynamics model of knowledge transfer based on system dynamics, testing the effectiveness of the supply chain knowledge transfer model on the Vensim software platform. Besides, further empirically analyzing the influencing factors of the supply chain by the evolution of the simulation and presenting the corresponding management.

Shredding auto-reconstruction is a hot research topic in pattern recognition. The research progress can produce certain effect to various fields. The purpose of this paper is to study shredding auto-reconstruction based on regular shredded document from shredders, to obtain a practical and efficient splicing algorithm to auto- reconstruction of strip shaped shredded text documents and block shapedshredded text documents. For strips, this paper uses the pretreatment, the similarity matching model, combined with the optimalHamilton path algorithm, for which we get a good result with 100% correct rate and no human intervention. For blocks, first, this paper pretreats the fragments. And then uses the row cluster model to divide all debris to some rows, and then uses the similarity model with direct reverse matching model to achieve the shredding auto-restore in different rows. At last, we use line spacing matching model to get the result that has a high correct rate reaching to 90% with little human intervention. In this paper, the design of some algorithms is original. Combined with the present feasible algorithm, we get an ideal result.
