Abstract: SQL Server skill assessment is deficient. This article describes the SQL Server object model SQL-DMO. Propose the process of SQL Server skill assessment: test paper generation, Skill assessment and Automatic marking. Analysis two key techniques of skill assessment based on SQL-DMO. One is getting operating information based on SQL-DMO. The other is automatic marking for Skill and Operation. Besides, automatic marking rules for database object creating, modifying and deleting are focused on. The author uses SQL-DMO method to realize database object information acquisition, and implement automatic marking for SQL Server database skill assessment.

Abstract: This paper analysises the feature and necessity of resource migration. And the main task of resource migration is to transfer the data and files among heterogeneous systems without data loss and error. So the logical structure model and relative components are defined in the paper and the function of the components and handling process of the middleware are described in detail. After these, The middleware program sample is developed and applicated between archives system and business system . In the end, the results and inadequacies of the middleware are analysised. It is seen that the middleware can solve the problems of data loss and confirm the stable operation of resource migration.

Abstract: In the view of current application software appeared complex, huge demand and update frequently, the frame technology is introduced to the software development process in order to improve the software development speed and quality. OSGi (Open Service Gateway Initiative) as a field development framework provides a good environment, system development based on OSGi has many advantages, including the dynamic change system behavior, it has hot swap plug in system structure, and with high reusability and efficiency. The paper constructs a Web application integration framework based on OSGi, which can effectively solve those problems of the framework development in the territory is complex, the integration framework’s reusability is better , and with easy extension characteristics.

Abstract: Display device is an important aircraft instrument to give airman swift and precise information. Attitude indicator is a typical picture which consumes more time on generating graphics than other pictures in aircraft cockpit. This paper presents a display device based on ARM. ARM generated and anti-aliased graphics using double frame buffers and overlapped them to input video. A filling algorithm was proposed to decide the color of a pixel in filling area, according to the connection between the pixel and horizon or outline. The display device decided the pixel color without writing the data into buffer. The algorithm reduces memory access and calculation, so the display device could generate an attitude indicator picture in 16.6ms which resolution is 1600×1200.

Abstract: Mobile GIS combines geographic information systems, mobile positioning technology, embedded systems, wireless communication technology and other technologies. It is the new direction of development of GIS technology. This paper first introduces the composition and features. Then development types, platform and languages are given detailed introduction. Finally the paper analyzes the problems of the development of mobile GIS and the prospect of Mobile GIS is presented.

Abstract: Embedded systems are used in many fields, but they are different from each other due to the varied practical conditions. Even for embedded devices installed under the similar situations, different control logic programs still exist. Covering the difference coursed by specific applications would highly improve the adaptability of the embedded devices. This paperwork presents a proposal that using Sedona Frame to improve the flexibility of embedded devices. In this paperwork, coupling plan and procedure are focused on greatly between Sedona Frame and device drivers and the feasibility of the coupling plan is proved using an instance of digital input devices. The advantage of graphic programming of Sedona Frame is discussed as well.

Abstract: Touch screen input system about hardware connection and driver design in uCLinux were presented in this work. With the respect of hardware, it introduced working mechanism of four-wire resistive touch screen and method of calculating coordinate. Then it presented the hardware connection of touch screen input system including touch screen, touch screen control chip and Microcontroller Unit. With respect of software, it analyzed the characteristic of driver design in uCLinux. Then it divided touch screen working process into six states which were ‘start’, ‘idle’, ‘wait’, ‘read’, ‘error’, ‘end’ and defined the state transition. On this basis, Touch screen driver design was introduced, which mainly included initialization function, clean function, device-opening function, device-releasing function, coordinates-reading function and parameters-setting function. It also gave the arithmetic converting touch screen coordinate to application coordinate.

Abstract: These years, rapid developments of Internet of Things provide powerful motivation to container freight. As the current situation, Framework of Container system and its basic infrastructure are all in starting stage, unanimous standard and hardware support are two obstructions for it. Considering that Container system will provide profound influences to Chinese market, the authors mainly design a CPS architecture of Container Management system and transplant software parts to Cloud computing platform. After that, the new container system will fully take advantage of Internet and reduce reliance toward computer’s hardware. After utilizing distributed software of Cloud servers, the management system will become much more efficient, providing a better service platform for consumers.

Abstract: Power information is a typical distributed interconnect system, faced with a complex network security problems. It still lacks a systematic method for the design and evaluation of system security. The authors comprehensively survey the layout of the power network and also ISO27001 international standards, and proposed a new security baseline reinforcement method for the power information system. By using the multi-class fuzzy comprehensive judgment model and the SSE-CMM method, the authors proved the reinforcement method is reliable in theory. This method combines ISO27001 PDCA model with the security baseline testing process, and applies ITU-T X.805 security architecture to the testing indicators extraction process, which makes the security evaluation process for the power information system quick and practical.

Abstract: The aim of dimensionality reduction is to construct a low-dimensional representation of high dimensional input data in such a way, that important parts of the structure of the input data are preserved. This paper proposes to apply the dimensionality reduction to intrusion detection data based on the parallel Lanczos-SVD (PLSVD) with the cloud technologies. The massive input data is stored on distribution files system, like HDFS. And the Map/Reduce method is used for the parallel analysis on many cluster nodes. Our experiment results show that, compared with the PCA algorithm, PLSVD algorithm has better scalability and flexibility.
