Abstract: Online homework correcting system based on ASP.NET is an online homework correcting system based on B/S mode, which can provide online work service for teachers and students to improve school teaching level. The characteristics of the system are making the traditional pattern of homework assignments and correcting networked, strengthening the connection between teacher and student, and also improving the teaching efficiency. How to use ASP.NET technology to build an online job submission and the process of correcting system, this article discusses the concept and characteristics of B/S mode, the superiority of ASP.NET and the analysis of general homework system. The system mainly completes the homework uploading and the teacher corrects for homework, it has high stability and simple operation.

Abstract: In wireless sensor networks, traditional link selection algorithm needs lots of data packages as testing samples, but the nodes of WSN are battery-powered, so the energy is extremely limited. To overcome this shortcoming, the aim of this paper is to propose three new link selection algorithms based the concept of Bayesian approach. Simulation results demonstrate that the three algorithms based on Bayesian approach have a higher success rate than empirical-algorithm by about 10 percent in selecting the highest quality link with the case of small samples. Among them, BSLA-EB has a good adaptability and it can get better experimental results.

Abstract: For some key fields like energy, traffic, etc., the system software has high reliability demands, so that monitors not only need to pay attention on the current action of the system, but also the prediction of future software behavior to avoid disaster. However once been deployed, the only determinate characteristic can be used to predict is just the static software information. In this paper, we construct the method for getting the monitor which can predict the future event at runtime, and experiment to study the effect on the origin program. The results demonstrate that the predictive monitor is generally helpful.

Abstract: With the rapid development of society, universities also develop its digital, intelligent business, which gradually increases the network data transmission needs. Wireless networks are an important part of the campus network, it is very important to build the campus wireless network as a supplement to a campus network. This design introduces a wireless network technology, and uses He Zhou College West Campus as a platform to design the campus wireless LAN-building program. The wired network and wireless network combine to provide better conditions for the campus information technology.

Abstract: Based on the technology of OpenGL and DirectX Wrapper, this paper designs and implements a new general method of data collection and display for the existing three-dimensional models using in multi-view 3D display system. Firstly, by using the technology of OpenGL/DirectX Wrapper, it obtains the application information such as the models, calls and associated data. Secondly, it sends the information to all rendering nodes. Then, according to the multi-view system projection array number and expected angle threshold parameter, each rendering node does the final adjustment and calibration on the obtained information sequentially for multi-view image rendering. Finally, each node transmits corresponding viewpoint image rendered by themselves to the projection equipment, and displays stereo images through 3D device synchronously. This method can be applied to all application programs based on OpenGL or DirectX Library. It is a general method for collecting and displaying multi-view 3D data sources. Experimental results show that this method is of high acquisition and rendering process, the image quality is the same as the source and stereoscopic displays strong. It has a wide range of applications and research value in the field of Engineering.

Abstract: Based on the university basketball teaching theory and practice,combined with module design theory.Using literature studies,surveys,interviews,computer network design and software development,testing feedback methods designed modern colleges.basketball network teaching courses.The system includes basketball theoretical teaching resource library,basketball skills teaching resource library, basketball learning online forums, basketball sports injuries advisory system and system maintenance updates five modules. Expounded the issue of the system design, key technologies, modules and functional design,running instances and so on. Research and development of the system provided a good network platform for the college basketball training,so make the existing basketball teaching and training network, made the quality of teaching to improve and enhance.

Abstract: The aim of this paper is to propose a new information fusion method for the problem of multi-sensor target recognition. Multi-sensor information fusion problem contains many characteristic indexes, and thus it can be regarded as a multi-attribute decision making problem. The new fusion method is put forward based on preference selection index method. The new information fusion method is not necessary to assign relative importance between attributes, but overall preference value of attributes are calculated using concept of statistics. Thus the new method can overcome the subjective randomness of subjectively weighting method. An applied example proves that the method is both effective and exercisable.

Abstract: Based on the analysis of several methods of storing OWL object in relational database, this paper presents a new method, namely storing the instances of each kind of object and attribute in a database table, and using views in the database to express relationships among the objects. Experiments prove that this method is applicable for moderate amount of storage of OWL objects.

Abstract: To improve the teaching efficiency, there is a need to deeply understand the operation mode of human body engineering. Through teaching practice to analyze the teaching process, with the method of analogy, found it is similar with the process of information transmission. In this paper, the transmission of information theory is applied to the teaching practice, teaching and learning model is established based on the information transmission theory.

Abstract: Big data has affected all walks of life including colleges and universities. The field of Secondary Vocational School has collected and stored vast amounts of educational data. In this paper, Learning Analytics is applied to information teaching platform of Secondary Vocational School based on Hadoop cloud platform. It can mine and use educational big data quickly and effectively, to improve teaching quality and meet the demand of individual learning for secondary vocational school students.
