On behalf of the Organizing Committee, I would like to welcome all of you to ICCASM 2010. This is a conference Co-organized by North University of China, Institute for Electrical and Electronic Engineers in U.S.A.(IEEE), and International Association of Computer Science and Information Technology (IACSIT), co-sponsored and supported Shanxi University, Taiyuan University of Technology, Taiyuan University...
With the rapid development of internal combustion engines (ICE) industry, the cross-section contour of variation elliptical piston skirt is widely used in order to achieve better mechanical and thermodynamics performances which the cross-section elliptic degree is diverse in the highness direction and the axis section contour is convex curve. Because of its complex form its geometrical precision evaluation...
Pulse wave of human body contains large amount of physiological and pathological information. Arterial elasticity letdown and arterial stiffness increase is significant marker of cardiovascular and cerebrovascular risk, so a vascular elasticity intelligent analysis system is designed based on LabVIEW. The main function of the system, such as data sampling, waveform pretreatment, feature extraction,...

The paper discusses principles and corresponding formulas of algorithms, besides, it analyzes in detail the precision of every intersection method and deduces all formulas of precision. Finally, paper summarizes before-mentioned algorithms...
With the development of educational information, the major concerns of the university are how to manage the current dispersed information unitedly and how to realize seamless share between information systems. This paper studies using web services to implement service-oriented architecture, puts forward data share model frame based on web service and XML technology, introduces the achievements of...
To the deficiency of marine refrigeration system simulation, marine refrigeration dynamic simulation system was developed based on real-time operation and management. Dynamic mathematical sub-models of marine refrigeration equipment was established by using the MATLAB. Then each sub-model was integrated as a dynamic composite model. In addition, the fault diagnosis, real-time operation and auto-evaluation...
Current methods used in image contour enhancement have the disadvantages such as distortion, replacement, great processing capacity, which restrict realtime application. To overcome the above shortcomings, a method based on lateral inhibition models was designed. The essence of lateral inhibition models and the meanings of parameters in lateral inhibition models were studied, and then the effect with...
Presently, the electret condenser microphone (ECM) is used in almost every consumer and communication audio application. In order to improve the efficiency of the circuit design, circuit simulation is necessary. In this article, we present a method based on Neural Network for modeling ECM, by which the fundamental characteristics of an ECM, including sensitivity, directivity, output impedance and...
Security and privacy are two prime barriers to adoption of the cloud computing. To address this problem on Infrastructure-as-a-Service model, a trusted cloud computing platform model has been proposed to provide a closed box execution environment that guarantees confidential execution of guest virtual machines. However this model has significant drawbacks that it relies on the trusted third party...
Based on our deep research in the last two years, our approach to implementing a cluster based real-time video surveillance system (VSS) has two features: (1) dynamic load cluster management mechanism is applied to automatic surveillance tasks dynamic assignment; (2) active blackboard is used as a service-load monitoring in the system. In this paper, we firstly explain the above-mentioned two features...
In order to sharpen image details and reducing noise, based on the multi-analysis wavelet threshold denoising method, a Labeling-based block-matching and wavelet transform filtering method combine hard and soft threshold denoising approaches (BWHS) is proposed in this paper. First, we estimate the noise variance of image. Second compute the matching blocks, and construct the 3D data array of those...
Because the integrated error measurement was not done in current micro-gear image measurement, the paper presents the virtual single-flank-meshing measuring methods of micro spur gear, and then introduces the principle, algorithm and digital simulation process of the virtual measurement. At first we constructed the standard involute spur gear, then the meshing process of the standard involute spur...
Accurate land use/cover (LUC) classifications from satellite imagery are very important for eco-environment monitoring, land use planning and climatic change detection. Traditional statistical classifiers such as minimum distance (MD) have been used to extract LUC classifications in urban areas, but these classifiers rely on assumptions that may limit their utilities for many datasets. On the contrary,...
When economists and politicians discuss the policies that could raise growth rates, usually fiscal policy takes centre stage. Using yearly data set from 1952 to 2008, this paper has proposed to use linear Granger causality to investigate the relationship between government expenditure and economic growth in China. The study finds that there is a strictly bidirectional Granger causality between the...
In this paper, a new attitude corrected algorithm based on conjugate gradient method is proposed, which is applied to the combination of accelerometers and a three axes magnetometer, and its principle is given, and the simulation of a rapidly rotating projectile's attitude test is done by using this method. The simulation results indicate that the algorithm can suppress the growth of errors effectively...
Internet is the biggest carrier of global information resources in 21st century. Domestic enterprises want to join in with product suppliers and customers only through the internet. This is the meaning of supply chain management systems. This paper proposed the solutions based on web model, introduced the web framework model, and analyzed the functional requirements of supply chain management information...
This paper proposes an effective speech endpoint detection method on the basis of the modified Bark wavelet transform. A new detection parameter is constructed by introducing a scale parameter into the nonlinear mapping, and combining the singularity information of the Bark wavelet transform coefficients in different sub-bands. Besides, appropriate threshold selecting rules are tested through simulation...
The papers discuss the temperature field calculation for solidification process of casting which based on cut cell. It deals with latent heat of solidification process with temperature recovery method. The temperature field of the dumbbell casting was calculated based on cut cell and zigzag mesh, the results show the calculation precision with cut cell is higher than zigzag mesh at the same grid size...
