摘要：
In recent years, online learning model has become the mainstream in higher education. The cooperation between universities and Internet education platforms provides a good learning environment and abundant online elective courses for college students, but the practical teaching effect is not ideal. Therefore, based on the Universal Theory of Acceptance and Use of Technology (UTAUT), this study introduced the perceived cost and content quality to build a model of college students’ continuous intention to use online course platforms, and used structural equation model to study the relationship among the variables. The results showed that effort expectancy and social influence affected continuous intention indirectly via performance expectancy; content quality indirectly affected continuous intention through effort expectancy, performance expectancy and effort expectancy–performance expectancy; perceived cost had a significant negative effect on continuous intention. These research results provide new ideas for the design and development of online course platform.

摘要：
With the development of modern science and technology and the wide application of new technologies in the field of education, the reading environment and reading style of primary and secondary school students have changed. "Internet +" reading has aroused people's extensive attention, and the reading effect and its influencing factors in the new environment are worth exploring. This study aims to explore the influencing factors of the "Internet +" reading effect of primary and secondary school students. This study used a linear regression method to answer four hypotheses. The results show that reading interest is significantly positively correlated with the reading performance of primary and secondary school students. In addition, reading habits, reading motivation, reading self-efficacy and reading effects were significantly positively correlated Through the discussion of the influencing factors of the "Internet +" reading effect of primary and middle school students, it provides a useful reference for the reading education in primary and secondary schools under the new situation in the future.

摘要：
Blended learning in the world has been drawing more attention. And lots of teaching methods in the blended learning environment have also emerged. This study attempts to examine the learners' continuous intention of the teaching method supported by Enterprise WeChat among college students who have taken "The Introduction to Educational Technology" class. In this study, five hypotheses were answered by using the linear regression. Results shows that perceived usefulness and learner satisfaction are shown to be good predators to behavior intention. Also, perceived usefulness and confirmation are significantly associated with learner satisfaction Confirmation is significantly positive with perceived usefulness. Main findings of this study were discussed, which could provide new ideas for future education.
摘要：
Obtaining the correct occlusion relationship between real objects and virtual objects is vital for improving augmented reality technology. In this paper, we propose a novel occlusion handling method using moving volume and ray casting techniques. Our method is divided into two steps. In the first step, we obtain the volume of the corresponding physical space and arbitrarily move the volume to extend the reconstruction area. In the second step, we calculate the 3D coordinates of each pixel in the scene and re-project the rendered objects to the same 3D coordinates system. Correct occlusion relationships are obtained by comparing the z coordinates of real and virtual objects. Several experiments are performed to validate the performance of the proposed method. The experimental results indicate that our method can correctly and rapidly handle occlusion.

摘要：
This paper introduces a new evolutionary algorithm based on the local search strategy and uses it to solve the Traveling Salesman Problem. The algorithm incorporates speediness of local search methods in neighborhood search with robustness of evolutionary methods in global search in order to obtain global optimum. The experimental results show that the algorithm is of potential to obtain global optimum or more accurate solutions than other evolutionary methods for the TSP.

摘要：
As a key technique of computational intelligence, evolutionary computation has attracted increasing interest because of its advantages of self-adaptation, parallelism, and robustness in solving complex and nonlinear problems. Based on the review of recent development of evolutionary computation and the principle of free energy minimization of thermodynamics, a new dynamical evolutionary algorithm (DEA) for solving single-objective optimization problems is proposed. The algorithm is used to solve some global optimal problems and satisfactory numerical results are achieved. The results show that DEA is of potential to obtain global optimum or more accurate solutions than other evolutionary methods.
