Abstract—Drainpipe ultrasonic non-destructive testing is liable to be interfered with the external environment. So it is important to remove the noise signal effectively in drainpipe ultrasonic non-destructive testing. The testing system is constructed by self-adaptive wavelet neural networks which is using the wavelet and neural network algorithm. Better fitting signal is achieved by choosing Orthogonal Daubechies wavelet neuron and optimizing the scale parameter. The simulation results showed less distortion and better noise cancellation.

Abstract
Keystroke rhythm is an identity authentication technique which takes persons behaviour characteristics as basis. In this paper, the PR-RP model were analysed, in which four critical dataset were choosed. P-P and R-R relay dataset were rebuilt, and were processed only through using characteristics of some user entering password. And then, so as to improve the recongnition rate of authentication, a new characteristics template was built and real-time updated, which make the data in template always to be the latest charateristics. In consideration of the above matters, this paper presents an Improved PR-RP Model. The experimental results show that this model can get satisfactory effect.

ABSTRACT: Traditional Fuzzy c-means (FCM) algorithm is commonly used in unsupervised learning. However, there are some limitations. Cluster number should be determined and the cluster center should be initialized before classification. A new algorithm is proposed in the paper. The best cluster number is obtained by analyzing cluster validity function and the cluster center is initialized by HCM. The data set is classified with Fuzzy c-means algorithm based on Genetic algorithm. The experimental results indicate the effectiveness and adaptability of the new algorithm.

Abstract—Clients can exchange data with embedded device where Web server is transplanted. In order to observe the state of the device and display it in the form of dynamic history curve, this paper has adopted two methods to get the real-time data of the embedded device and display the curve. One uses JavaScript cooperating with VML (Vector Markup Language), the other uses Applet. The two methods both have good displaying effect. The first method is complicated. It demands that clients install IE browser. The code of the second method is simple but needs the installation of JRE on the client side. These two methods have a quite bright prospect and can be applied in various fields.

Abstract—Based on the input-output data , a multiple-model modeling method is suggested for the complex nonlinear system. Firstly, fuzzy partition is employed to on-line clustering for the input-output data; and then, the least-squares (LS) algorithm is employed to construct the local model for each clustering, and the parameter of each local model is updated by the new data. The proposed algorithm takes advantage of the TSK model, combines the fuzzy partition and multiple-model modeling, and updates on-line the number of the local model and the parameter of each by the input-output data, so as to realize the on-line modeling for the complex nonlinear system. Simulation result shows the effectiveness of the proposed method.

Abstract—Singular Value Decomposition(SVD)Filtering is one seismic data processing technique which uses the lateral coherence difference of the seismic wave to achieve wavefield separation and denoising. As the differences of propagation characteristics, apparent velocity and coherence in seismic signals, transformation of the valid signals may be transformed into those with better coherence by some mathematic transformations. In this paper, based on apparent velocities, throughing the processing method of two times Normal Moveout(NMO), we make the P-P wave and the P-S wave moveout respectively that enable them to achieve the best coherence on the deflection. The goal is that transforms the desired signal to one kind better processing territory in the horizontal upward coherence, then distinguishes two times SVD respectively and reconstruct signal with extracting the singular value of target signals. we might accomplish P-P wave and P-S wave separation as well as noise attenuation afterwards.

Abstract: The H-infinity mixed sensitivity tracking control method is applied to the vibration control of high-order flexible structures and a method for the choice of the mixed sensitivity weighting matrix is put forward. A MIMO (multi-input multi-output) control model of a vibration system is established which induced model uncertainties via the H-infinity control theory and the mixed sensitivity design method is used to design the robust H-infinity controller. An augment plant for the vibration system is presented by introducing the weighting function matrices. A MIMO control model with two inputs and two outputs is set up by a cantilever beam for simulation. The results show that the H-infinity controller designed for the high-order flexible structure can satisfy the requirements of the internal stability of the control system and the tracking specifications.

Abstract— The problem of semi-supervised dimensionality reduction with kernels called KS2DR is considered for semi- supervised learning. In this setting, domain knowledge in the form of pair constraints is adopted to specify whether pairs of instances belong to the same class or not. KS2DR can project the samples data onto a set of ‘useful’ features and preserve the structure of unlabeled samples data as well as both similar and dissimilar constraints defined in the feature space, under which the samples with different class labels are easier to be effectively partitioned from each other. We demonstrate the practical usefulness and high scalability of KS2DR algorithms in data visualization and classification tasks through extensive simulation studies. Experimental results show the proposed methods can almost always achieve the highest accuracy when the dimension is reduced. And KS2DR methods outperform some established dimensionality reduction methods no matter how many numbers of constraints, dimensions are used.

Abstract—An algorithm of target tracking based on adaptive waveform design was proposed with the help of Doppler estimation theory. According to the analysis of the ambiguity function for liner frequency modulation signal, a model between ambiguity function of the signal and Cramer-Rao bound of time and frequency delay was built. This paper realized the target tracking by adjusting the frequency width and pulse width using Kalman filtering method. With the same signal energy and noise environment, the simulation results show that the proposed adaptive tracking algorithm has a better tracking precision than the method which makes use of the constant parameter.

Abstract—Most parts of rotating machine rotate cyclically when the machine fails for some reason, and the vibration signal of rotating machine often has the cyclostation character. Aiming at this feature, Degree of Cyclostation(DCS) was presented to analyze the fault trend of rotating machine in this paper. DCS was constructed by the comparison between third-order non-stationary cyclic moments and stationary cyclic moments. It evaluated the cyclic frequency with the binary decision method and it could reflect the non-stationary character of vibration signal and suppress the noise and interference of the signal. In the experiments of analyzing the fault trend of rotating machine, DCS could get better trend result than the traditional vibration amplitude and vibration intensity.

Abstract—For multilayer sandstone reservoir , high permeability water passage would be formed between oil well and water well at the later stage of water drive. This caused the injected water circulation with no or low efficiency and thus decreased the production of oil wells. In order to improve the effect of water drive, measures of profile control and/or water shutoff must be taken. The key problem is to recognize the wells and layers having ineffective or low-efficiency water passage. In this paper, the identifying indexes have been determined and corresponding mathematical model has been constructed with fuzzy theory.

Abstract—An optimal planned route is a foundation of safe and economical navigation. This paper proposes a method for the shortest distance routing in a chart based on testing a spatial relation of a linear route segment and an obstacle area. Firstly, safety contour traces are traced and obstacle areas are acquired automatically. Then possible optimum paths circumambulating an obstacle are searched automatically by comparing the spatial relation of the linear route segment and the nearest obstacle area. Finally a route binary tree is constructed and the shortest route is obtained. Experimental results demonstrate that the proposed method has more advantageous over traditional methods in efficiency, accuracy and reliability.
