Abstract: Good cartoon producing functions of Flash plays an important role in mutli-media teaching system. FLASH can be used to show some abstract concepts and phenomena. It is not difficult for teachers to use Flash. It is discussed in this paper to how to use Flash cartoon function in teaching. It is also dicussed Flash designing roles, designing thoughts as well as designing procedures.

Abstract: It proposes an interactive logistics warehousing system solution based on virtual reality technology by the actual logistics warehousing system. The system, employing the improved MVC framework of software design patterns, builds virtual environment model and logistics warehousing 3D model by 3dmax and Pro/E, meantime, achieves Warehousing and outbound operation in inventory management by using SQL database technology. In addition，it overcomes some interactive insufficiency on the VRML through Java3D, and solve some key problems. Therefore, it has a certain practical value and broad application prospect.

Abstract: A Enterprise Application Integration system named Enterprise Information Platform is designed and implemented in a J2EE environment to ensure data share across any operating system and network. Based on message mechanism, JMS is used to transfer message and XML is chosen to organize the format of communication data which can provide services and application programming interfaces to integrate heterogeneous data. This system has been successfully used in some enterprise, and its generality, openness, multiplexing and extensiveness has also been proved in practice.

Abstract: To overcome the deficiency of descriptive ability, cross-platform ability and interaction in existing workflow system, this article proposes an interactive workflow management system based on J2EE technical. The system uses hierarchical description's method to simplify the workflow model, supports the visual modeling, and has the good interaction. The practical application shows that the system has obvious advantages on enhancing descriptive power, reducing the modeling complexity, strengthening model interactivity ability and cross-platform ability.

Abstract: This paper introduces a data transmission circuit used to transmit signals over thousands of meters in borehole; meanwhile, a control system that is equipped with the circuit is also presented here. This set of equipment has many advantages over previous systems-smaller size, less cost, longer communication distance and friendlier user interface. The design of hardware in the system consists of LVDS transceiver circuit, USB port circuit based on high speed MCU C8051F321, automatic power-on circuit based on relay TQ201 and acquisition circuit based on 24-bit analog-to-digital converter LTC2492. The software is based on both C language and VC++6.0. Finally, it accomplishes a kind of data transmission circuit and control system in borehole which delivers the data from thousands of meters away.

Abstract: Urban surface temperature distribution is closely linked to its ground vegetation cover. Determining the correlation between the urban surface temperature and its ground vegetation has an important role in the urban surface temperature improvement and the urban environment optimization. This paper selects the TM data in the summer of 2009 to obtain the normalized difference vegetation index (NDVI) and selects 129 samples in the seasons acquired by the images to do the actual measurement of the surface temperature. Then it analyzes the quantitative relationship between the surface measured temperature and normalized difference vegetation index finding out that there exists a negative correlation; Their regression fits to obtain the type of relationship: Ts = 37-14.64 * NDVI. The identification of the correlation between the urban temperature and vegetation index provides a relatively reliable theoretical basis and technical support to the urban planning, and urban ecological environment construction.

Abstract: This paper introduces the concept and function of the Scalable Vector Graphics (SVG). According to the basic principles of the drawing palisade connected graph, the method of drawing the palisade connected graph is finally achieved in consideration of such key technologies as the number and connection of the layers, as well as how to eliminate the hidden lines, and by employing the water injection wells data. Furthermore, it also shows how to realize the zooming and dragging of the palisade connected graph through the SVG technology. Ultimately, combined with the data background of Daqing No.2 Oil Plant water injection wells, this article illustrates the implemented effect of the palisade map.

Abstract: In the grid environment, there are a large number of grid resources scheduling algorithms. According to the existing Min-Min scheduling algorithm in uneven load, and low resource utilization rate, we put forward the LoBa-Min-Min algorithm, which is based on load balance. This algorithm first used Min-Min algorithm preliminary scheduling, then according to the standard of reducing Makespan, the tasks on heavy-loaded resources would be assigned to resources that need less time to load balance, raise resource utilization rate, and achieve lesser completion time. At last, we used benchmark of instance proposed by Braun et al. to prove feasibility and effectiveness of the algorithm.

Abstract: Massive data stored in a cloud database, in which lots of potential and valuable knowledge exist. In this paper, the data model of the cloud database is analyzed. Through analyzing, classifying, the common features of the data are extracted and form a feature data set, from which the new knowledge can be found. In the paper, the basic model based on the classification characteristic rules of the cloud database is defined, and the discovery algorithm of the classification characteristic rules is presented.

Abstract: Data de-duplication divides backup stream into chunks and eliminates duplicate chunks across the entire system, thus remarkably reduces the storage and bandwidth requirement for backups. However, this technique also introduced many new problems among which the performance problem has been resolved by many of the existing solutions, while the logical data deletion problem is not well studied till now. This paper studied the logical data deletion mechanism in de-duplication backup systems, analyzed the memory overhead of the Bloom filter, which supports both high performance de-duplication and logical data deletion, and proposed a lazy deletion method to minimize the influence of logical data deletion on de-duplication performance.
