Design and Implement of WebGIS Based on SVG

SVG based on XML is a kind of language describing 2D vector graphics.It is usability and applicability to set up WebGIS.The paper puts forward a system structure of WebGIS based on SVG,which has been applied to campus electronic map system of Chongqing University.It has been proved the method is feasibility and practicability.The paper sets forth some key techniques of implement of the system in detail: coding method of organizing SVG spatial data;generation of SVG electronic map;storage of SVG spatial data and implement of client.     

Developing Method Based on Object-oriented Modeling Techniques for Management Information System

A developing method is given which based on object-oriented modeling techniques for management information systems.The modeling techniques,especially,from CDM to PDM conversion,make it possible that the method can be used for developing such management information systems which based on relational database.The result shows that it can raise the efficency of the system developing,improve the system tability,enhance the system maintenability.     

System Design for Leather Cavity XCT

This paper introduces a method of solving the problem of leather cavity measurement in shoe CAD/CAM by industrial CT technology. Concentrating on peculiarity and requirement of leather cavity measurement, this paper presents a X-ray industrial CT system scheme, which not only satisfy the requirement of leather cavity measurement but also can achieve general industrial CT. measurement. The achievement on data collection system and motion control of stepping motor is emphasized.     

Adaptive Intrusion Detection System Based on Agent and Data Mining

Intrusion detection system is an essential component of network security protection mechanisms. Most intrusion detection system can not adapt the variation of network environment. Aiming at this problem, an adaptive strategy that composed of condition space and strategy space is proposed. The condition space describes the network environment and the strategy space describes the strategy. There is an exclusive strategy corresponds to a certain environment state in condition space. On the base of the adaptive strategy, an adaptive intrusion detection system based on agent and data mining is designed. The simulation experiments indicate that the adaptive strategy is effective.     

Research On Flying Animation System Driven by Data

Larger quantities of data about flight performance and flight condition are recorded by flight data recorder (FDR) during the aircraft's flying. It is an importance task to make 3D flying animation from the data on the process of flight data. The design ideas and realizing methods about the software of flying animation system driven by the data from relation database are presented.     

Data Loading Technology of Data Warehouse

Data warehouse is not the simply data accumulation of operational database. For exerting the function of data warehouse, the construction of data warehouse should be convenient for the data mining and business intelligent work, supply information access, analyze, and share for decision maker. The key to constructing a successful data warehouse is to fully understand the demand of end users from beginning to the end, search and storage data surround users motive closely. This paper first analyzes the data warehouse characteristic and the sort of data component, emphasizes in effective data loading methods and strategies from operational database to data warehouse, gives five sorts data loading methods.     

A Product BOM Management Method Based on Single Layer BOM

Bill of material of product is data about product structure, and plays an important role in product information management. The paper analyzed characteristics of product BOM, and put forward a product BOM management method based on single layer BOM, witch can well meet requirements of product BOM.     

Philosophy of Science and the Chinese Contemporary Architectural Forms

Philosophy of science led by Popper is one of the most important contemporary scientific and philosophic theories.In addition to the science,the philosophy of science impacted contemporary social science mostly,of which the false-feasibility,circumstantial logic,anti-historical determinism and anti-scientism influenced the orientation of contemporary architecture.Just with these factors of philosophy of science,this thesis reanalyzed and reviewed Chinese contemporary architectural forms,especially the tradition inheritance.     

基于DEA的农业机械上市公司经营绩效分析

运用数据包络分析法的C2R模型对2003～2005年农机上市公司的综合效率进行分析、对比、研究,发现我国农业机械上市公司平均效率较低,且公司间效率值差距显著;不同年份之间,部分公司效率值波动较大;效率值与各子行业经营方向有关,零部件制造企业的经营效率明显优于整装设备制造企业。
