Published: June 2013

With the increasing for crane in the industrial production, its structural reliability has now been an important concept to guarantee stable performances. The structural safety for the traditional stochastic and probabilistic reliability method is both measured with the viewpoint of probability.

Aiming to these problems, the reliability analysis based on possibility theory is supplied. The method abandons two value state hypotheses, and can avoid a large number of sample collection and the impact of human factors. Compared with the probability methods applied to the crane structure, the possibility reliability method is not only feasible, but also reduces the computational error.

Authors: Wei Li Wei , Xiao Qiang , Zhang Ying , Ji Xiong Fei
Published: June 2013

Least squares support vector machine (LS-SVM) has an outstanding advantage of lower computational complexity than that of standard support vector machines. Its shortcomings are the loss of sparseness and robustness. Thus it usually results in slow testing speed and poor generalization performance. In this paper, a least squares support vector machine with L1 penalty (L1-LS-SVM) is proposed to deal with above shortcomings. A minimum of 1-norm based object function is chosen to get the sparse and robust solution based on the idea of basis pursuit (BP) in the whole feasibility region. Some UCI datasets are used to demonstrate the effectiveness of this model. The experimental results show that L1-LS-SVM can obtain a small number of support vectors and improve the generalization ability of LS-SVM.

Authors: Gu Lei
Published: June 2013

The locality sensitive k-means clustering method has been presented recently. Although this approach can improve the clustering accuracies, it often gains the unstable clustering results because some random samples are employed for the initial centers. In this paper, an initialization method based on the core clusters is used for the locality sensitive k-means clustering. The core clusters can be formed by constructing the σ-neighborhood graph and their centers are regarded as the initial centers of the locality sensitive k-means clustering. To investigate the effectiveness of our approach, several experiments are done on three datasets. Experimental results show that our proposed method can improve the clustering performance compared to the previous locality sensitive k-means clustering.

The Description of the Semi-Local Hardy Space by Gabor Frames
Authors: Feng Jin Shun
Published: June 2013

Materials science is an interdisciplinary field applying the properties of matter to various areas of science and engineering. In this work, the notion of the binary generalized multiresolution structure (BGMS) of subspace is proposed. The characteristics of binary multiscale pseudo- -frames for subspaces is investigated. The construction of a GMS of Paley-Wiener subspace of L^2(R^2) is studied. The pyramid decomposition scheme is obtained based on such a GMS and a sufficient condition for its existence is provided. A constructive method for affine frames of L^2(R^2) based on a BGMS is established.

Published: June 2013

According to the current situation that banana pesudostem resources are rich in china while the utilization of stems and leaves is insufficient. the development situation of the banana pesudostem mechanization treatment are summarized. And this paper points out that the low level of banana pseudostem mechanization has become an important factor restricting the development of the banana industry in China after analysis. Combining the research status of pseudostem mechanization treatment, this paper discusses its development tendency and proposes several potential ways of mechanized treatment, providing a reference for improving the level of mechanization of the banana industry.
Overseas Offshore Reservoir Quick Forecast by Sedimentary Facies

Published: June 2013

There are more and more overseas offshore oil project in china, along of external interdependent level in petroleum becomes upgrading year by year. Therefore, developing quick forecast method on overseas offshore reservoirs becomes very necessary. The method is divided into three steps: i the core data analysis results are used to calibrate the interpretation about logs of well, ii the well log interpreted results are used to mark seismic data, iii the abundant seismic data is used to forecast overseas offshore reservoir quickly. And rear end in this article, an overseas offshore reservoir is used to as an example to verify the applicability and reliability of the method.
Research on Automotive Panel Stampings Production Process Financial Control Process
Authors: Zhang Zhijuan
Published: June 2013

The right panel stamping forming is an important prerequisite for generating qualified parts, an important step before the panel forming simulation is to determine the reasonable forming of the stamping. Manually adjust parts in order to overcome rely on experience, the drawbacks to the stamping forming, the forming of the stamping punch and forming the contact area of the sheet as the goal of automatic determination control process. Objective function of the forming of the stamping for the variable contact area in the stamping forming of the feasible region, the use of heritage control processs to optimize the objective function of the contact area and, ultimately feasible within the contact area corresponding to the stamping forming, that is the best stamping forming. The measured results show that the forming of the stamping based on genetic control process, the automatic control process can fast and accurate to obtain the optimal forming of stamping.
Chaos Synchronization Between Unified Chaotic System And Rossler System
Authors: Wu Hao , Xu Bo Lun , Fan Chang , Wu Xian Yong
Published: June 2013

In this paper, two synchronization schemes between two different chaotic systems are proposed. Chaos synchronization between unified chaotic system and Rossler system via active control and adaptive control are investigated. Different controllers are designed to synchronize the drive and response systems. Active control synchronization is used when system parameters are known; adaptive synchronization is employed when system parameters are unknown or uncertain. Simulation results show the effectiveness of the proposed schemes.
