In this paper, the author studied the construction of an e-commerce enterprise platform for college students. This paper presents the applications of e-commerce and discusses an online sales system (online shop) constructed on multi-tier technology infrastructure. The multi-tier architecture signals a powerful computing trend and has a profound effect on both enterprises and web-based applications. Online purchases are processed on computer applications that support ordering and paying. The experiment results show that the adoption of Internet standards, which is associated with the enormous popularity of the Web, has changed the architecture of distributed computing. The multi-tier architecture of the Web is an ideal environment for the development of component-based applications, specifically small online shops.

Aiming at the fact that the classification performance of support vector machine (SVM) highly depends on the parameters selection, a parameters optimize method of SVM based on improved fruit fly optimization algorithm (LFOA) was proposed. The steps of SVM parameters optimize based on LFOA was proposed, and the superiority of the algorithm in convergence speed and convergence accuracy when compared with some other methods is verified by simulation experiment of several standard datasets. Take the rolling bearing as experiment object, the common faults was diagnosed by LFOA-SVM The experiment results show that the LFOA improved the classification performance of SVM and has higher accuracy compared with FOA, GA and PSO, and can applied to fault diagnosis efficiently. © 2017, Editorial Department of JOURNAL OF MECHANICAL STRENGTH.

To study the detachment stress on the ripeness of strawberry fruit, physiological characteristics of strawberry fruit on and off plant during ripeness and senescence processes were investigated. The results indicated that the ripeness of strawberry fruit upon detachment was accelerated, in terms of firmness, soluble solid content and especially color development. The color of fruit off plant changed rapidly from white to full red in 1-2 days. The respiratory rate in fruit off plant was strengthened, higher than that on plant. Abscisic acid level and ethylene production in fruit off plant were also higher than those on plant and auxin degradation was exacerbated by detachment. Expression levels of FaMYB1, FabHLH3 and FaTTG1 were generally reduced with phenotypes of redder color and more anthocyanin accumulation in fruit off plant. Results also suggested that the detachment initially stimulated ethylene and abscisic acid production and auxin degradation, which modulated ripening-related gene expression and at last enhanced fruit pigmentation. © 2014 Franciszek Górski Institute of Plant Physiology, Polish Academy of Sciences, Kraków.

A visual saliency detection method is proposed in this paper, which is fulfilled in a fully automatic manner. We regard the likeness of a pixel to its surroundings as local feature. Self-resemblance measured between local features results in a map where each pixel indicates the statistical likelihood of saliency. Our method is compared with other saliency detection approaches using an acknowledged public image datasets. In addition, we apply our proposed method in the application of image retargeting and object segmentation. The experimental results show that our algorithm outperforms the other state-of-art methods.

This paper is concerned with the problem of delay-dependent passivity analysis and passification for a class of stochastic impulsive neutral systems with mixed delays. To reflect more realistic dynamical behaviors of the system, the stochastic disturbances are considered, which are given in the form of a Brownian motion. By constructing a proper stochastic Lyapunov-Krasovskii function as well as the linear matrix inequalities (LMIs) technique, some novel sufficient conditions are derived to ensure the delay-dependent passivity/passification performance in terms of LMIs. Finally, a numerical example is given to illustrate the theoretical results. © 2012 IEEE.

In order to fully exploit the useful information of winger Time-Frequency Spectrum, a fault diagnosis scheme based on winger distribution of vibration signal combining with singular value decomposition is proposed in this paper. Firstly, winger distribution is applied to analyze the original vibration signal, then, analysis to winger spectral matrix based on singular value decomposition is conducted, and characteristic sequences which reflect the mechanical fault state is achieved, finally, taking the singular value of winger spectral as eigenvector to do the fault diagnosis with Support Vector Machine (SVM). The experimental results show that this method can effectively extract fault features. ©, 2015, Journal of Mechanical Strength. All right reserved.

In this paper, we use the Windows as computer operating environment, VC software as development platform, USB and Access as data interface, and design the CAN bus detection platform of vehicle maintenance, and use parallel technology to improve the platform function. Improved detection platform has the capacity of parallel computing, which greatly improves the speed of vehicle maintenance. In order to verify the effectiveness and reliability of detection platform, we use the CAN bus hardware as a test environment to test the CAN bus detection platform. Through the test we found that, during the same range of detection time, method of CAN bus will detect more times than general detection method, the fault detection rate is higher, which is a very effective method for detecting and repairing automobile. It provides the technical reference for the study of automobile repair and detection. © (2014) Trans Tech Publications, Switzerland.

This paper investigates the observer-based H ∞ control problem for a class of discrete-time Takagi-Sugeno fuzzy neural networks with both random communication packet losses. The random data losses are described by a Bernoulli distributed white sequence that obeys a conditional probability distribution. In the presence of random packet losses, sufficient conditions for the existence of an observer-based feedback controller are derived, such that the closed-loop control system is asymptotically mean-square stable and preserves a guaranteed H ∞ performance. Finally, a numerical example is provided to illustrate the effectiveness of the developed theoretical results. © 2013 Springer-Verlag Berlin Heidelberg.

A new auto gearbox bearing fault diagnosis method is put forward based on Winger distribution and SVD of vibration signal. Firstly, bearing vibration signal was analyzed by Winger distribution; then, signature sequence was obtained by SVD, which can reflect the gearbox fault condition; finally, singular values of the vibration signal Winger spectrums were selected as feature vectors to diagnose fault based SVM. Experiments show that this method can extract fault feature effectively. © (2014) Trans Tech Publications, Switzerland.
