ECG signals often are mixed with the myo-electrical interference, the power frequency interference and the baseline drift, and traditional filtering methods have certain shortcomings, which badly impact on the detection and the analysis of ECG(Electrocardiogram) signals, so we use Wavelet Transform to filter out noise interferences of ECG signals for the above mentioned problem. Firstly, coif4 wavelet is adopted to scale decompose ECG signals containing noises, secondly, the soft and hard threshold value quantify high-frequency coefficients of every scale, finally, the wavelet reconstructs high-frequency coefficients of every scale which are quantified by the threshold value to get ECG signals being filtering. Experiments show that Wavelet Transform has well real-time and good filtering effect, and it has more obvious advantages more than traditional methods.

Grid technology and applications become mainstream distributed computing research in recent years. The Grid Harvest Service, GHS, is one of non-dedicated computing grid scheduling systems; it has been widely used in Grid research field. The contribution of GHS is providing appropriate prediction for long-term applications different from AppLes which is designed for short-term predictions. GHS maps metatasks using the Min-Min algorithm in a uniform log-term application. Min-Min is a highly efficient algorithm in an uniform workload environment that leads to load unbalance and low performance when the workload is not uniform. In order to solve the problem, a novel task scheduling algorithm is proposed in this work, which is an adaptive task scheduling algorithm based on Min-Min and Max-Min (A-MM). A-MM merges the high efficiency of traditional Min-Min scheduling with load balance of traditional Max-Min scheduling. The simulation and experimental result show that A-MM has better performance and scalability than the Min-Min of GHS.
网格技术及其应用成为近年来分布式计算研究的主流。网格收获服务(GHS)是一种非专用计算网格调度系统;在网格研究领域得到了广泛的应用。GHS的贡献是为长期应用程序提供适当的预测，而苹果是为短期预测而设计的。GHS使用Min-Min算法在统一的长期应用程序中映射元任务。Min-Min算法是一种在均匀负载环境下的高效算法，但在负载不均匀的情况下，会导致负载不均衡和性能下降。为了解决这一问题，本文提出了一种新的任务调度算法，即基于Min-Min和Max-Min (a - mm)的自适应任务调度算法。A-MM融合了传统Min-Min调度的高效率和传统Max-Min调度的负载均衡性。仿真和实验结果表明，A-MM比GHS的Min-Min具有更好的性能和可扩展性。

Web services are emerged as a popular application for implementing large-scale distributed, reactive systems. Web service composition is the hotspot research in the field of Web services. Because the validity is a key requirement in the description of Web service composition, a formal language XYZ/ADL is introduced which describe the composition from the view of architecture. In this paper, we define a mapping from XYZ/ADL to a more practical approach of Web service composition BPEL4WS which is difficult to verify the validity of the composition. First, define the conversion of XYZ/E to BPEL4WS, analyze the similarity between the design elements in XYZ/ADL and activities in BPEL4WS, and then do the conversion of XYZ/ADL to BPEL4WS.

Based on the technique of code obfuscation in software protection, a new obfuscation scheme in constructing opaque predicates was proposed, which increased the complexity by employing the pseudo-random sequence and a group of Diophantine equations’ solutions to construct a family of parameterized opaque predicates. To protect the output of the opaque predicates, the data chain list was dynamically generated. Pseudo-random sequence was also used to disturb the attackers’ tracking debug. The complication of decompile was increased through block cryptosystems that convert the output of the opaque predicates into the corresponding judge conditions.

Image denoisng algorithm based on independent component analysis is proposed. The standard independent component analysis algorithm require that the number of sensors is more than or equal to that of sources, so it is impossible to apply independent component analysis to single channel image denoising directly. In this paper, a single channel image denoising algorithm is proposed by constructing a noise image to as another observation signal for single channel noise reduction based on independent component analysis, thereby noise and original image can be separated through independent component analysis. Simulation result shows that much better denoising effect and signal-noise ration can be obtained by using this algorithm.

In order to solve the problem about the recognition accuracy, Tchebichef moment invariants and support vector machine (SVM) are adopted to recognize the vehicle-logo. It extracts six invariant moments of the object as feature vectors, and then uses the support vector machines (SVM) to recognize vehicle-logo. Tchebichef moment invariants perform significantly better than Hu moment invariants and Zernike moment invariants. The result of these experiments suggests that this system has a high recognition rate in both noise-free and noisy environment which has high practical value.
