Abstract: The biggest challenge for heterogeneous network is co-channel interference problem, and due to the presence of interference, the system energy efficiency reduced greatly. In previous studies that use of space resources to eliminate interference between heterogeneous networks , most are based on the receiving end with a single antenna case to use zero forcing (ZF) beam-forming algorithm , however in practice the receiving end often configure multiple antennas, so this article use Block Diagonalization (BD) beam-forming algorithm to eliminate inter-cell interference after considering the coordinated multi-point transmission processing technology. This paper defines a energy efficiency metrics and convert it into a convex optimization problem by mathematical methods, and the improved energy efficiency programs is obtained ultimately.

Abstract: The system uses the MVC framework model for system integration, processing data through the view, the controller reads the data from the view, and send the model to control user input data, the model object is responsible for accessing data in the database. Using the controller decoupling performance logic and business logic, in order to improve system maintainability, scalability and reusability, effective separation of business logic, data, and interface display implementations.

Abstract: Teaching ability is the essential factor of the teacher’s professional quality and it is also the strong support of the quality of elementary education. Especially along with continuous advancing the reform of the new curriculum, the degree of the teacher’s teaching ability is already a key of the effect of reforming curriculum smoothly. Practice shows that the effective developing the research of teaching is an important way of enhancing the teacher’s teaching ability. But with the help of the advanced network technology, especially the network research of teaching by implementing the mobile platform technology, it can effectively improve the limitations of the relative single and closed traditional research of teaching, it is also the inevitable trend of developing the teacher’s teaching research. With the in-depth development of economic globalization and the progress of science and technology change rapidly, the talent competition is becoming increasingly fierce, as the countries all over the world to training to a new strategic height. Is a project of vital and lasting importance, education for the. And educational plans, the teacher as the. In the educational activities, teachers are to promote the development of education is the soul of teachers, schools at all levels and in the classroom and the key activities of the educational reform through all the channels of education of the people.

Abstract: This paper analyzes the present situation of higher vocational college student management work, designs and realizes students' information management system based on Java technology. This paper realizes to insert, query, modify, and delete the students' information. The system improve the efficiency of student information management and promote the informatization construction in higher vocational college.

Abstract: College English writing, as one of the most important skills of college English teaching and learning, can reveal the English comprehensive level of learners. The development of computer and Internet creates conditions for college English teaching reform. This paper explores what influence will be caused when students write autonomously under the network environment and probes into a new method of college English writing teaching through studying autonomous learning mode of college English writing based on constructivism.

Abstract: With the development of information technology, the Internet has become an important tool for ideological and political work. Internet will use preference characteristics to promote the network ideological and political work in a more effective development. This paper used literature review, questionnaire survey, site investigation, comparative analysis, comprehensive analysis, the above two aspects will carry on the quantitative analysis and in-depth discussion, in order to provide new methods and ideas for other research in related fields, but also to provide quantitative basis and theoretical basis for the follow-up study. This study is the inevitable result to promote the higher education, science development requirements, which are network measurement and trend.

Abstract: After 9/11, container transport security and efficiency gain more and more concern, the secure and smart container concept is put forth by the USA for national security firstly. Based on the questionnaire survey analysis, this paper puts forth the exact concept and function of the secure and smart container , analyzes related key technology and elaborates detail technical solution based on The Internet of things how to make the common container become the secure and smart container.

Abstract: With the development and popularization of technology of computer application, network and database, the network based training exam mode has been widely used in place of the traditional exam based on paper-pencil and book ways for it is efficient, fair, safe and reliable. To against the current lack of network test system design, this paper proposes design ideas to dynamically generated answer options of standardized test. Through improving the database design and optimizing test generation algorithm, a network test system with dynamically generated answer options is designed to effectively promote the effect of learning and training of the candidates.

Abstract: with the development of computer technology, network communication technology and multimedia technology, multimedia teaching has being widely used, especially in colleges and universities.This paper emphatically presented the application situation of radio frequency identification technology (RFID) and wireless sensor network technology (WSN) in internet of things technology in the existing problems of multimedia teaching equipment management, and explored its application effect.

Abstract: The creative city takes the lead either in economy or culture. In recent years, China continuously proposes the test point for creative city and expends the exchange between economic development and culture. However, the environmental pollution has always been the major problem with economic development. There are numerous researches and explorations on the environmental pollution, left behind by creative city. The paper uses analytic network process (ANP) makes a comprehensive assessment on the environmental pollution of the creative cities of Shenzhen, Guangzhou and Nanjing. Firstly, summarize the factors that affect environmental pollution, using analytic network process; secondly, start evaluation from atmosphere pollution, water contamination, soil heavy metal pollution, which make up the environmental pollution system; establish digital format for environment indicator system, create hypermatrix model and work out the corresponded conclusion.
