This paper presented a dynamic implementation plan for operating database and its tables aimed at the problem of lacking of flexibility when using database in a system based on B/S structure. After abstracting user's requirement model, then through using metadata indirectly implemented user's operatings, which makes the business logic and data processing abstracted in a relatively independent way...
Most of the incremental association rule mining methods must rerun through processed data and have not made the best of the given rules. In this paper we propose an incremental association rules algorithm, this algorithm applies artificial immune theory and takes advantage of the given rules produced by original data set. Based on the quickly response during the memory cell recognizing the antigen,...
The original measurement system of wave-plates phase retardation is non-automated, low efficiency and not suitable for a large scale wave-plate measurement. In order to solving these problems, this paper designed an auto measurement system of phase retardation of wave plates based on LabVIEW, computer, PCI-1753 digital I/O card, and some photoelectric conversion instrument. The hardware part of it...
In order to satisfy the needs of comprehensive and accurate performance test for CPS (Control and Protective Switching), an automatic performance test system was studied in this paper. The hardware structure and software was introduced in detail; the hardware system was made up of the industrial control computer, the three-phase current generator, adjustable single-phase power, pneumatic fixture,...
Data processing in the complex system generally the data is complicated and the data processing outcome is strictly. In order to deal with these problems researched the algorithm of variable precision rough set integrating neural network. It has powerful functions in data mining, data reducing and data classifying aspects. It is proofed by an example that this algorithm can process large and imprecise...
In the digital processing of mould, this paper presents a new method to improve the accuracy of the edge of mould with optical scanners and three coordinate measuring machine. According to researching lots of IGES files of CAD/CAM systems, this paper presents a method for transforming reference point datum to IGES file. The processing system can transform the data measured in different coordinate...
In this paper, it proposes a design idea of automatic weather station based on GSM module TC35i according to the characteristics of automatic weather station. The system implements data collection and processing through the AVR SCM and realizes remote data transmission in GSM public Internet through GSM module TC35i by Siemens.
In order to predict the related attribute values of the typhoon data affecting factors from the aspect of the intrinsic relationship of the center wind force, maximum velocity of wind and center air-pressure, which is based on structural risk minimization criteria of the support vector regression (SVR) method to establish the “wind force and speed - center air” SVR prediction model, selecting the...
