Abstract: The main technological equipment of subsea construction vessel is diving complexes and hardware, in various combinations thereof. It is proposed to link the task of classifying vessels of this class with the classification of the subsea equipment they serve, in order to form the basic data of a perspective vessel. For this purpose, an analysis of function of subsea construction vessel was carried out and their design features were determined. Using the analysis performed, a first approximation evaluation of study effectiveness was carried out. The analysis of the results and the search for the optimal solution makes it possible at subsequent stages of research to develop a methodology for finding the optimal solution when choosing equipment.

Abstract: The enterprises when the designer worked with CATIA. In order to improve the efficiency, the research took the shaft parts as the research object to realize the secondary development of CATIA V5R18. The development platform of Shafting parts was set up through the embedded component development environment of CATIA CAA RADE and CAA API and was based on the development platform of VC++. At the end, this paper took the typical parts as examples to introduce the method of system operation. The test results show that this system could realize the rapid design and enhance the design efficiency, and it could provide the experience for the deeper development of CATIA.

Abstract: With the aim of planning preventive measures of seismic protection, estimation of possible damages on building constructions plays an important role. In order to predict the category of damage , a data base was formed out of the data from reports submitted by the commission of the Faculty of Technical Sciences in Novi Sad. The paper presents the research on the influence of the number and structure of input data and the comparative results of prediction of damage category on building constructions for two models of ANN (ANN-1 and ANN-2)

Abstract: According to the communication mode between different series of inverter and different series of PLC, the database model of communication protocols and parameters is built; then query application software is developed for the establishment, modification and searching the inverter communication network configuration. It is built with VC++ as the foreground, SQL Server as the background database support. The main function modules include communication parameter management module, communication program information management module and information query module. Results show that it can quickly provide communication scheme between the commonly used inverter and PLC for the industrial site and technical personnel.

Abstract: The tools developed in the design of retaining structures focus mainly on aspects of design and stability analysis of the structural components. We propose in this paper the construction of an information base that serves not only to calculate conventional retaining structures, but can also help in the selection of the optimal type of structure, best suited to the economic and environmental situation of a project. For this purpose, we begin firstly by a general patterning of retaining structures, and then, we conduct a systematic analysis of the retaining structures built in its environment, to detect any kind of existing interaction and interrelation. Structuring and formalizing the derived information is the last step of this work. We present in this paper only an information base that eliminates the bad retaining structures related to the project context.

Abstract: Printing system of college educational administration has been managed by artificial, which result in low efficiency and high human cost. So we build a system by docking the software and hardware system of background database based on IC card to realize self-service printing for teachers and students of college, which provide a high-efficiency, convenient and humanized service mode, and enhane the economical sense of teachers and students for creating a green campus.

Abstract: Base64 is one of the most common encoding styles to transfer 8 byte code in the internet. Base64 is used widely, through which the data is usually put in URL. However, the mark % as a wildcard will be generated after encoding by standard Base64. Therefore, Base64 after URL encoded could not be directly stored in the database. To solve the problem, this essay presents a improved Base64, which can be directly stored in the database. The reconfigurable and flexibility of FPGA, the design by Verilog HDL and the comprehensive line used by Quartus II 13.0 can be achieved. Eventually, adaptation to the DE2 development board is tested. Practice has proved that there are many merits of the system, such as: simple structure, fast operation speed and good flexibility and so on.

Abstract: Taking the design of automotive product as an example , the designing thought of PDE technology was made full use of This article . On the basis of establishing components figure library and data base of the chassis parameter, by the secondary development of VB and AutoCAD 2000 software, and blending the drawing design of automobile product and data management, this is automobile product data management（the abbreviated is APDM）. To some extent，the system has performed the virtual design of automotive chassis. It can design automotive and inquire data fast and efficiently. Thus it reduces the designer’s labor intensity and raise designing efficiency.

Abstract: Because rural distribution network has complex structure and various operation management things, geographic information system is the effective means to display the operation conditions and to improve the management efficiency of rural distribution network. In this paper, we studied and developed the PowerWEBGIS system based on WEB and specially used the technology of combining with the real-time monitoring system, which is more suitable for the rural distribution network management. The effectiveness of this system has been confirmed through its application in the several power supply companies.

Abstract: According to the characteristics of electrical discharge machining in gas, a reference voltage adjustment module was joined into the traditional reference voltage comparison gap state control system, to constitute a closed-loop gap state control system. The proposed gap state control method is expected to improve machining efficiency and machining accuracy of electrical discharge machining (EDM) in gas and improve the automaticity of electric discharge machine tool in gas. Meanwhile, it also has certain reference value for the traditional electrical discharge machining gap state control.
