Abstract: the processing capacity of a server is unable to satisfy the parallel processing of mass data and also improves data transmission in storage system. This paper has adopted active storage system to transfer calculation task and management ability to data end, improving the parallel processing capability of application program and reducing the data transmission rate in the system. During processing arriving process, this research has complied with Poisson flow, and the service time for each processor is negative exponential distribution and task service rule is the mixing model of “first come, first served”. Through experiment, it is proved that the data transmission rate within MMC system is reduced by 15% than random allocation of task on average and the system speed-up ratio is improved by 2.1 than average.

Abstract: This paper focus on two level hierarchical scheduling where several real-time applications are scheduled by the fixed priority algorithms. The application with its real-time tasks is bound to a server which can be modeled as a sporadic task with special care for the schedulability analysis. Different scheduling policies and servers can be applied for hierarchical fixed priority systems, this paper gives a closer review of schedulability analysis for applications and tasks when the global and local schedulers of a system are fixed priority.

Abstract: Ontology mapping is the technological foundation of semantic integration, ontology merging and ontology alignment. In this paper, we propose approaches of ontological property mapping based on multi-strategy. First we use different strategies to deal with data type property and object type property. Then the optimal property mapping results of multi strategies are chosen. Finally, we present experimental results with high accuracy and point out future possible research directions.

Abstract: In the standard target system of specialty accreditation, assessed results of teaching process are required to reflect students level of mastering related knowledge. Examination score is the most direct and important reflection. In this paper, VBA programming was applied to generate score sheet of main curriculums in recent years which is required in self-assessment report for specialty accreditation. Firstly, original data were obtained from information management system of teaching affairs. They are teaching task files and class score sheet, which are all Excel files. Secondly, original data were handled by VBA according to requirement. Compulsory courses for civil engineering class and scores for first exams were selected. Thirdly, average scores and first passing rates were calculated. At last, a summary score sheet was produced which is helpful to analyze students learning effect and to find out reasons. Therefore, the efficiency of analyzing teaching results for specialty accreditation is greatly improved.

Abstract: E-mail has become one of the most important applications on the Internet. At the same time, computer crimes involving e-mail increases rapidly. To prevent these phenomena from happening, the authorship identification methods for Chinese e-mail documents were described in this paper, which could provide evidence for the purpose of computer forensic. E-mail form features to classify authorship were extracted. To classify the author of Chinese e-mail, the SVM(support vector machine) algorithm was adopted to learn the authors features. Experiments gained satisfactory results on limited dataset. The accuracy of dataset for four authors was 92.56%. The satisfactory results showed that it was feasible to apply to computer forensic.

Abstract: Food safety has been in the spotlight of the global attention. In 2013, Chinas food safety supervision policy was undertaken a major reform. China Food and Drug Administration (CFDA) takes over the responsibility of food safety management, which in the past was conducted by different government sectors. Under this new management system, how to carry out the practical work has become a new issue. This paper introduces an innovative food safety management mode adopted by Guizhou province. On the basis of latest information technology, food production enterprises, government, testing organizations and consumers are integrated into a unified food safety information service cloud platform. The core technology of cloud platform is composed of food safety knowledge system, testing management system, food safety information publicity system as well as mobile application. The food factory inspection data, government inspection data, testing organizations testing data and consumers purchasing information are integrated into food safety and nutrient test big data. Utilizing the data to explore the information that is needed by all the parties, this paper tries to provide a solution to the risk exchange problem faced by Chinas food safety issue. At the same time, food safety problem can be solved through the contribution of different stakeholders.

Abstract: The network size of China Mobile Multimedia Broadcasting (CMMB) has expanded rapidly, and population coverage ratio has significantly increased. Meanwhile requirements of users to CMMB network coverage have risen higher and higher. How to know the situation of CMMB network coverage accurately and resolve the problems of it timely and effectively has become the primary task for CMMB network coverage workers. In this paper, based on the design requirements of CMMB coverage analysis system and data system, the E-R diagram was adopted to realize the database design of three physical objects: coverage information, map information and user information. Furthermore, a logical structure model of database was created and the design process of database in CMMB coverage analysis system was analyzed in this paper, which can provide a reference for further development and optimization of CMMB coverage analysis system.

Abstract: This study proposed that the origami curriculum can be one of the important educational activities for Grade 1-9 because origami is not only a form of arts, but also possesses the learning functions that involve hand-brain-eye co-ordination and can upgrade learners non-classical logic deduction skills. This study uses Huzitas Axioms and Huzita-Hatori Axioms (HHA) to implement the Web of Origami Simulator (WOOS). WOOS is produced by a computer algebra system (CAS) and it allows users to arbitrarily rotate or zoom origami forms, calculate the length of line segments, calculate area, and measure angles. Moreover, the steps taken can be recorded so that learners can observe the entire process after the activity. WOOSs ultimate objective is to be implemented in the origami or algebra teaching activities of junior and elementary schools.

Abstract: This paper attends to study Windows Server and SQL Server to form a combination of the two operating systems to establish an online learning platform. The platform basically completed the user needs to achieve functional, but also focuses on the application of Ajax technology, the use of this technology at the user level can be completed without page refresh can be achieved through video effects, the data layer, it reduces the data access to the database pressure, improve the overall performance of the overall learning platform, the results show that the techniques of this paper can be used in a very good application and online learning platform.

Abstract: According to the characteristics and needs of virtual scenic roaming system, select the appropriate modeling techniques. By using the modeling platform scenic entity object model structure, and then build virtual tourist attractions, we propose hierarchical collision detection methods. This method actually meets the accuracy requirements under the premise, greatly reducing the number and complexity of collision detection; effectively improve the system in real time.
