Abstract: For the teachers of teaching basic computer programming language, a very large number of student programs should be graded and human graders have great difficulty in judging the correctness and efficiency of programs. A programming assessment method is proposed based on program slicing technique and the method has reduced the complexity in the assessment of large-scale program by decomposing program. The method divides the program into several slices by generating program dependence graph and on those slices we can get the score of the student program by comparing the student program with the template program. The method has successfully improved the grading process and it is also employed for the undergraduate courses.

Abstract: This paper describes the theory and method of programming under the environment of UEFI Shell and also introduces the UDK2010.UP4 install and configuration. The program run in UEFI Shell can get EFI Boot Services through the EFI_SYSTEM_TABLE parameter, after this it can operate disk files through Simple File System Protocol and EFI File Protocol. The work in this paper mainly introduces some file operations in UEFI Shell, such as file creating, data access on a FAT file system disk through a UEFI Application (UEFI App hereafter).

Abstract: Multi-QoS and Trusted resource management and Task Scheduling are key problem in cloud computing. This paper presented an effective Multi-QoS and Trusted resource management model and Task Scheduling algorithm in Cloud Computing Environment. By using the idea of fuzzy clustering for reference, the proposed approach can subtly schedule the Cloud tasks to appropriate resources that exactly meets its’ multi-QoS needs of resources. Considering the credibility of cloud resources, the credibility and trusty of task scheduling has been dramatically improved.

Abstract: In planning approval field, AutoCAD data format is used widely, for it is convenient to map.However, for massive planning approval data, it is difficult to query the corresponding spatial and attribute characteristics by AutoCAD files. While ArcSDE can unifiedly manange spatial and attribute data, whose strong database management is inherited from relational database. To address planning approval field interoperation problem between AutoCAD and ArcSDE in planning approval data management system, we took redevelopment from AutoCAD to ArcSDE database based on C#.Net and Object SDK. The data could be operated by Down-Load and Up-Load module in the system. Down-Load module was developed to load planning data from ArcSDE to AutoCAD, Up-Load module was to store AutoCAD format data into ArcSDE.As a case study,the modules were integrated into the Planning Approval Data Management System for Yueyang city and the data interoperation was very fast and easy between AutoCAD and ArcSDE+SQL Server 2008. The results show that the implemented interoperation function is convenient for planning approval data management.

Abstract: The explosion of information in the World Wide Web is overwhelming for readers with limitless information. Large internet articles or journals are often cumbersome to read as well as comprehend. More often than not, readers are immersed in a pool of information with limited time to assimilate all of the articles. As technology advances, it becomes more convenient to access information on-the-go, i.e., portability of information by utilizing mobile devices. In this research, a semantic and syntatic based summarization is implemented in a text summarizer to solve the information overload problem whilst providing a more coherent summary. The objective is to integrate WordNet into the proposed system aka TextSumIt which condenses lengthy documents into summarized text. The empirical experiments show that it produces satisfactory preliminary results on Android mobile phones.

Abstract: A kind of modeling method of regular ground object in virtual city was proposed through splicing certain spatial simple geometries based on VC++ and OpenGL, which combining the ground objects’ characteristics with modeling realistic demand. This method firstly generated some basic shapes (cylinder, cone or sphere) which were the constituent parts of regular ground object, by using simplified 3D basic geometry modeling method of OpenGL. Then joined these basic shapes together by doing coordinate transformation to construct the regular ground object. The case of modeling street lamp was taken as an example to introduce the ground object’s modeling methods and visualization technology. The modeling process just need calculating a small number of coordinates, and the amount of data is also very low. Experimental results show that generated models looks very real.

Abstract: AutoCAD is a wildly used software in kinds of industries, while the depth of its’ applications is limited by its weakness on attribute data management. This paper commences with the introduction of AutoCAD xdata, discusses the way to input, output and modify the xdata, and represents the key code in C#. Finally, this paper probes into both the application process and application characteristics of xdata by demonstrating the example of planning approval.

Abstract: The Software Engineering can be considered a new area. During its recent history, many techniques applied for managing and producing software have been taken from Industrial Engineering. It is known that issues related to achieve the deadline, cost and functionalities are being discussed and are still a challenge for software development. This paper aims to propose a software development process model based on concepts of Industrial Engineering. Besides, the paper discusses some standards and models from Software Engineering that helped in the development of the model proposed. The result of this work is the model itself, together with some future works proposed to continue the research.

Abstract: Grid based data warehouse (GDW) distinguishes itself from other data warehouses based on single computer, parallel computer, cluster, or distributed network due to the characteristics of the grid environment. This article proposes an approach for GDW. GDW approach is good at adapting different hardware platforms and bottom databases by making full exploitation of the heterogeneity and transparency of the grid .

Abstract: Based on the introduction of smart substation function architecture, the analysis method of use case was firstly recommended to study the main business information system of smart substation, involving protective relaying and automatic control. During analysis, demand of information interaction in lengthwise and crosswise direction and limits of the existing system was pointed out. Then in guide of system theory, control theory and information theory, integrated-control idea was proposed to improve the existing control system framework, the integration-control model and system architecture were analyzed. Finally, the project application of yan’an was given.
