Abstract: Office Automation (OA) means office and management automated. OA is a comprehensive technique. It contains the computer technology, communication technique, the system science, behavior science, and so on. It can deal with massive, indefinite tasks which traditional data processing technology may do difficultly. By each enterprises and institutions, all branches of government have different business and functions, so the market demands of OAS are also differences. The general structure of the OA and the system has been designed by analyzing the workflow model in COAS. It enables dynamic tracking business process.

Abstract: The common data acquisition system which is proposed in this paper has achieved features of monitoring layer and data collection layer (Complete the construction of ARM9 system board hardware and software environment; implement the design of STM8L acquisition board; design such application modules as host MODBUS, slave MODBUS, parameter setting, real-time data communications, real-time graphical display, local data storage, ADC, digital filtering and so on). Judging from the system test, it can achieve the desired effect, and especially, STM8L ADC data acquisition board has highly precise and consumes low power.

Abstract: Let G(V,E) be a simple graph, k be a positive integer, f be a mapping from V(G)E(G) to 1,2,...k. If uvE(G), we have f(u)≠f(v),f(u)≠f(uv) ,f(v)≠f(uv) ,C(u)≠C(v) , where C(u). Then f is called the adjacent vertex-distinguishing E-total coloring of G. The number is called the adjacent vertex –distinguishing E-total chromatic number of G. In this paper, the adjacent vertex –distinguishing E-total chromatic number of the multiple join graph of several kinds of particular graphs is discussed by using construct coloring function.

Abstract: From information technology point of view, analyzed the theoretical and practical background of data mining processing massive amounts of data. Based on the definition and basic concepts of data mining, discussed and analyzed 5 aspects of its main task. Described the data mining process comprehensively. Integrating with the problems within the Apriori Algorithm, described the improvements to the Apriori algorithm. And, in the end, summarized the role of data mining technology in promoting the development of computer technology.

Abstract: Situation assessment (SA) is essentially a reasoning process based on knowledge, thus knowledge base is one of the most important components of SA system. According to the analysis of situation shaping process, this paper defines the needs of battlefield decision-making on SA system, designs a primary structure of SA system based on knowledge base and expatiates its operation.

Abstract: The characteristics of hyperspectral data with large number of bands, each bands have correlation, which has required a very high demand of solving the problem. In this paper, we take the features of hyperspectral remote sensing data and classification algorithms as the background, applying the ensemble learning to image classification.The experiment based on Weka. I compared the classification accuracy of Bagging, Boosting and Stacking on the base classifiers J48 and BP. The results show that ensemble learning on hyperspectral data can achieve higher classification accuracy. So that it provide a new method for the classification of hyperspectral remote sensing image.

Abstract: The article narrates the construction of scientific research project management system based on workflow. The business logic is independent from the specific functions. Scientific research projects are unified and orderly managed, and automation and Overall coordination of the management system is improved. The organization of the system can be made more smoothly. The work processes are more flexible and adaptable.

Abstract: During processing database query or dealing with huge amounts of data, the conventional query method is not only a waste of resources but also may perform repeated or useless operations which may cause the database overburdened even. For solving the problem of time-consuming in conventional database query, this paper presented a more convenient solution to the problem in conventional database queries. This paper constructed an XML document to simulate the database and transformed the database query into the XML queries. Experiments showed that speed can be significantly improved for database query and better results can be obtained.

Abstract: In this paper, through introducing the Williams public-key cryptosystem in detail, the analysis of the characteristics of the system, and the combination with zero knowledge proof, we set up a zero-knowledge proof scheme based on Williams public-key cryptosystem. The scheme will enrich the theory of cryptography, and particularly zero-knowledge proof theory.

Abstract: A new, common-path, in-axis concentric beam-splitting Michelson interferometer is demonstrated for optical coherence tomography (OCT), which can be used to perform high-resolution cross-sectional in vivo and in situ imaging of biological tissues. A piece of glass tube with its inner diameter smaller than the beam-width of the collimated light is used to split the light into a reference and sample beam. In order to obtain the optimal spectral interferogram of this OCT system, an infrared optical path adjustment method was introduced in this paper.
