The symmetrical matrices in geomatics have been generated every day, and their scale have been increasingly and rapidly expanded. The existed data management of symmetrical matrices has been increasingly faced with some great difficulties and challenges. This paper introduces briefly our works on a new expanded relationship database management system, the symmetry-relationship database management...
This paper present the calibration method of color CCD temperature measurement system based on image processing according to bicolorimetric method. According to the experimental results, the relation between red, green and blue brightness is established. This method is employed to calculate temperature. The calculated result shows that the relative errors are small by this method. It is a fundamental...
In this paper, we design a improved FTP search engine model which is introduced on the basis of customer feedback information and made server reliability, practical resources, customer neighboring degrees weighted standard in order to ensure that when the search results are too large, in front of the display is always excellent resources.
This paper researches the approaches of data repairing for expendable current profiler. The self-learning algorithm of the network architecture based on generalization ability has been developed. Proving experiment using the algorithm has been done, which confirms the algorithm can increase the precise of data gained from the expendable current profiler.
In order to realize office automation, management standardization and modernization of the ammeter management in locomotive depot, we have designed the ammeter administration subsystem in the office automation system of locomotive depot. The system point out a new way for solving the energy statistic problem of locomotive depot and railway electricity department by adopting many methods, such as wireless...
The goal of OpenGIS specification is to solve the geodata sharing and interoperable geoprocessing. This paper first made a study of OpenGIS specification, emphasized on SFO (the simple feature specification for OLE/COM), then proposed an embedded GIS component based on the simple object model and on the characteristics of embedded devices. The component was designed by using of object-oriented technology...
In view of the special characteristics of cam grinding, some key technologies of grinding force adaptive control system are researched in this paper, including a selection of inspection parameters, a model of grinding feed system, and the design of controller. Results of simulation indicate that this system can ensure a steady circular grinding force and enhance the machining quality of cams when...
Social network encourages users to show interest based Web collections of resources on the Web in a collaborative fashion. Social network systems aim at the automatic recommendation of interesting content to users about their interests and the context of interaction based on a model of folksonomy. The paper presents an interest based recommending framework for social network, and also gives a formalized...
The algorithms and the applications of the wavelet transformation and wavelet analysis theory in filtering and denoising of MEMS gyro are presented in this paper. Gyro signals were decomposed into different scales by some basic wavelets to discard wavelet coefficients by soft threshold methods. Then the signal is filtered after wavelet reconstructed. Examples with actual experiment demonstrate that...
This with the development of sports and modern computer technologies, a great deal of data were recorded, including training data of athletes, test data of students in sports course, and test data of physical health standard (PHS). However, usage of these records is limited. Patterns and relationships among data may still retain hidden. Data mining, usually applied in business fields, is a helpful...
In order to search for the gap between Chinese oil enterprise and international oil companies in the marketing force, use the close value method to evaluate the marketing force of nine major oil companies in the environment of Excel. Find out that there are differences in the close value of the nine major oil companies and the level of every company's marketing force orders one by one by analyzing...
The paper gives the object-oriented multi-scale retrieval theory for educational image resources. (1) from the actual needs of education and teaching, analyzing the object-oriented features of image for educational resources; (2) descriptors for image of educational resources are systematically presented according to the object-oriented features of image for educational resources, which have nothing...
Based on the fuzzy classifying approach, the paper puts forwards a diagnosis algorithm of Back-propagation Neural Network. For some complexity environments, the traditional Back- propagation Neural Network has some limitations on classification. The paper applies fuzzy model on Neural Network structure, by using classifying variance and energy function to adjust the convergence of the Neural Network...
Soil contamination with heavy metals will lead to losses in agricultural yield and hazardous health effects as they enter into the food chain. The lead contamination exerts a wide range of adverse effects on growth and metabolism of plants. In present studies, we investigated the effect of lead on chlorophyll fluorescence of wheat leaves with confocal microscope. The digital images of chlorophyll...
In this paper, firstly we introduces the subsystems of the tax management information system. Then we establish the layer framework of tax management information system, including page framework, application framework and data framework. The tax management information system can improve the taxation service, reduce the taxation cost, and provide reliable reference for macro-economic decisions.
This paper introduces a kind of novel Fuzzy Phase Locked Loop(PLL) controller for induction heating power supply control.A novel PLL is designed with fuzzy control technology, which using fuzzy controller replace the traditional low-pass filter (LPF) to improves the control accuracy and response time. For more, the fuzzy-controlled PLL controller for induction heating supply system have been analyzed...
A novel hyperchaotic system with one nonlinear term and its fractional order system are proposed. Furthermore, synchronization between two fractional-order systems is achieved by utilizing a single-variable feedback method. Simulation results show that our scheme can make the two systems synchronized.
Most of signals are non-stationary signal in reality, and the analysis methods are based on time-frequency domain or time-scale domain. An invertible transform method based on time series is proposed in this paper from another point of view. Using this method to analyze the broadband noise signal, experiments show that this method can turn disorder to order in time domain. And after transform, their...
As a comprehensive communication, information and command system, the coalition emergency response system (CERS) is integrated with communication, computer, network, GIS, GPS, graph, image, video monitoring, database and information processing, etc. This system is a new hot research at present. However, the CERS can only be found in a few big cities such as Beijing, Shanghai and Nanning. Thus, it...
