Many time series database applications require processing and analyzing database sequences where the focus is on finding the patterns and trends in sequence data. In this paper, we propose a new approach based on the observation that finding sequential patterns in databases is somehow similar to searching for a phrase in the text. However instead of searching for sequence of letters usually from finite...
A new image fusion algorithm based on lifting wavelet transform is presented in this paper. The source images are decomposed using lifting wavelet transform respectively. Aiming at the coefficients of low frequency and high frequency, this algorithm choose a different rule to fuse the image. To the low frequency, the spatial frequency based on the neighborhood add consistency check is elected as the...
With the development of network technology, the future network is an open and reconfigurable network architecture whose functions are reorganizational, capabilities are programmable and managements are reconfigurable. According to the feature of the future network that is application-oriented reconfigurable, this paper proposed a design of integrated network management system. The system is based...
A novel low-voltage low-power PMOS cascade current mirror employing the bulk-driven technique is described in this paper. Based on SMIC 0.18μm CMOS process, the characteristics of the low-voltage bulk-driven cascade current mirror are analyzed and validated, including the input/output resistance, the system dc transmission error, the frequency characteristics and noise performance, etc. The simulation...
Through the systematic research on image segmentation and genetic algorithm applications in image segmentation, this paper proposes some improvements for the traditional genetic algorithm and applies the improved genetic algorithm in image segmentation. The experimental results show that the improved genetic algorithm this paper proposed can quicken the convergence, while maintaining the population...
The paper described the cutting process analysis with CAD systems by drilling. The start of process is defined from cutting process (with one the cutting edge). Simulation of machining (cutting and drilling). Finite Element Method (FEM) based techniques are used to simulate high speed machining processes and offer several advantages including prediction of tool forces, distribution of stresses, and...
In this paper, a novel image zooming method based on the boundary effect is proposed, which combines the advantage of the nearest neighbor interpolator and the bilinear interpolator in edge zooming area. Comparing the proposed method with the above two traditional interpolation algorithms, the result of computer simulation reveals that the former has higher performance, especially for the image containing...
In the perspective of host country, the impact of location factors for Chinese OFDI choice is examined in this paper. Based on theories of FDI location choice, combining with the features of OFDI of emerging economies represented by China, 9 variables are chose, 6 models are built, and 4 hypotheses are proposed, then the factors that affect Chinese OFDI location choice is verified through the regression...
A prediction model of agricultural mechanization is studied by means of applying Grey System theory and BP Neural Network (GMBPNN). The method is illustrated by example, and the results obtained by using the GMBPNN method are compared with that from GM (1, 1) and BP neural network prediction methods. The simulation results demonstrate the efficiency of our proposed algorithms, which offers a new way...
The color forest dynamic inspection images corrupted by some noise are a large amount of original information obtained in the processing of defending the forest diseases and insect pests. Based on analyzing three color image attributes such as resolution, pixel depth and true color or pseudocolor, it is separately presented what are the external evaluation rules about the means and effect of the forest...
This paper is concerned with the problem of robust stability and stabilization of large-scale singular systems with norm-bounded uncertainties in both the derivative and state matrices. By using a parameter dependent Lyapunov function, a proportional plus derivative (PD) state feedback decentralized controller is designed for the closed-loop systems to be quadratically normal and quadratically stable...
Crop germplasm resources investigation is the basis of the crop germplasm resources work and has significant meanings for the protection and utilization of crop germplasm resources. With the development of computer science and technology, resources investigation means and devices are improved, such as notebook computer, PDA, mobile phone etc. Because of the features of small switch delay and security,...
