With the rapid development of computer technology, various distributed-component technologies are emerging. CCM specification, which has the features of independent of platforms and development languages, complete model, standard protocol and interface, has been widely recognized in computer industry. In this specification, the reuse of software is achieved through assembling. Its openness and extensibility makes it especially suitable for the integration of large-scale information system. Based on the introduction of CCM specification and information system integration, proposes the application of CCM specification to information system integration, and describes the integrating method from four aspects of integration framework, hierarchy structure, development process, and operation characteristic.

In accordance with the Coupling vibration absorber system, introduced to reduce the vibration of the wheel loader at driving, designed are two dynamic models for the loaders either with the application of vibration absorber system or without that of it. The simulation analysis of the vibration reduction, with the help of the simulation software Matlab/ Simulink, shows that the vibration absorber system may reduce not only the vehicle vibration effectively but also that of the work device, thus providing the basis for the further research and development of the riding control system.
applications are generally designed and developed with little regards to security consideration. Fortunately, there is abundant of processes and technologies today that is available that can be used to easily secure a...

3D geological modeling is an inter-discipline subject applying computer technology to the geological research. With the development of Internet, 3D geological modeling based on Web has become a hot spot. In this article, we applied the Flash3D technology to the 3D geological modeling based on Web. We designed a process which use borehole data as original data source, automatic interpolation and identify strata from it, then calculate modeling data. We developed a 3D geological and geographical system based on Flex and Java platform using Flash3D engine technology. The system is a true 3D geological modeling software in B/S mode.

An audio signal acquisition and analysis system with low-cost and high performance was developed, taking LabVIEW as the software development platform and the computer sound card as hardware platform. This system is capable of audio signal acquisition, real time dynamic display, analysis processing, storage and display of audio signal. Practical application shows that this system not only has those advantages such as high-precision, stability, reliable performance and being easy-operated, but also can achieve common data-acquisition within the designed frequency range of the sound card. The signal acquisition technology based on the sound card, especially the technology combining with virtual instruments has broad prospects in the field of engineering test measurement and teaching practice.

Extension is a new subject which solves contradictory problems. It studies the extensive possibility of things and the rules and methods of exploitation and innovation with formalized model. The extension control theory and method has provided the basis theory and method for people to solve the existent contradictory questions in the automatic control system such as stability, accuracy and speed. This paper briefly introduces the related basic concepts of extension control, such as the structure of canonical extension control, extension set of character status of basic extension controller, and general extension control algorithm, and so on. Also presents the extension application in power systems. The future work and prospect of development are described.
