It is difficult for a single classifier to resolve the problem of high dimension in the hyperspectral image classification applications. Combination of multiple classifiers can make full use of the complementary of the existing classifiers, thus owns better classification performance. A novel multiple classifiers based on C5.0 decision tree is proposed. It reduces the hyperspectral dimension through wavelet-PCA transform algorithm firstly. Then three supervised classifiers, namely Minimum Distance, Maximum Likelihood and SVM, combined by C5.0 decision tree, are used to realize hyperspectral classification. Experiments based on AVIRIS hyperspectral image data show that higher classification accuracy may be achieved via the multiple combined classifiers than a single sub-classifier. The proposed method can reduce the dimension of features and improve the classification performance efficiently.

Example-based interpolation is a powerful method to interpolate function from a set of input-output examples. In this paper, we argue that total three desirable properties should be satisfied so that the interpolated solution can cross all the given examples with minimal oscillations among the examples. We also show that, as long as the number of given examples exceeds the dimension of example and meanwhile there does not exist one hyper-plane, in real vector space of example's dimension, passing through all the given examples, one simple interpolated solution, which is expressed as a sum of two terms: an example-influence term that consists of the outputs of a number of basis functions, and a linear term, does allow all the three desirable properties to be satisfied exactly.

Web server cluster has been widely used to improve web server's performance. In order to help web providers select the appropriate pair of scheduling algorithm and cache replacement algorithm, and to help researchers evaluate new scheduling algorithm or cache replacement algorithm under different client access patterns, this paper designs and implements a trace-driven scheduling algorithm and cache replacement algorithm simulation platform based on JavaSim for web server cluster, called WSCSim. It models the serving time of static and dynamic requests respectively according to their deferent traits, supports traces of different formats, and can simulate complicated algorithms for Java's powerful function. In WSCSim, trace parser, distribution, scheduling algorithm and cache replacement algorithm are extensible; therefore user can add new components to the platform. Especially, Java interface and Java dynamic proxy technique are used to guarantee the Plug and Play (PnP) characteristic of these extensible components. Simulation tests show the feasibility and validity of WSCSim.

The paper takes Yinchuan plain as a research object, and basically investigated the quaternary geology and the spatial distribution and structure characteristics of groundwater system. The method of virtualizing boreholes is used to increase borehole data in accordance with the well-developed geological structures, the complex strata and lithology, the multiple geomorphologic units, the large area and the unevenly distributed boreholes. Based on the platform of geostatistics and Groundwater Modeling System (GMS), the three-dimensional geological structure model has been set up which reflects the hydrogeological conditions in the study area and the visualization of hydrogeological structure has been realized. All of these provide the foundation for exactly evaluating groundwater aquifer and rationally developing and utilizing groundwater.

A photo sequence captured with different focal settings is called a focal stack image. By merging the focal stack image we can obtain an all-in-focus image. A merging strategy is introduced in the image fusion process with spatial image transform. A fusion selective function is formed using Laplacian transform and image gradient based on the focal stack photography. Two other methods in spatial domain are compared as well as the proposed method.

The safety evaluation of petroleum resources based on Grey Correlation-TOPSIS is simple but practical, scientific and reasonable with certain application value. The safety evaluation of petroleum resources based on Grey Correlation-TOPSIS applies approximation coefficient of grey correlation for evaluating the safety degree of petroleum resources and effectively overcomes the shortcomings that the conventional ranking method of approximation to ideal solution cannot fully explore the similar information of data. The ranking result is as follows according to the relative approximation coefficient: America, Germany, Japan, China and India.

OpenVPN is an open source Virtual Private Networks product providing cross-platform, secure, highly configurable VPN solutions. Tablet computers seem to be directing many of the emerging trends in the marketing industry at the moment. For this case study, the performance of OpenVPN on Android is measured and analyzed using various configurations parameters including protocol, cipher and compression. The results show that the throughput is mainly impacted by the data compression used, and that the round-trip time is mostly dependent on the transport protocol selected.

Breast cancer is a very deadly disease for women. For the time being, mammographic screening remains the most effective method for early detection of breast cancer. However, reading mammography is a time-consume error-prone work. Therefore, many computer-aided detection and diagnosis systems (CAD) have been developed to assist radiologists in detecting and classifying mammographic mass. Most of those CAD system used single classifier for the classification of mass patterns into benign and malignant, or normal and mass or calcification. Increasing number of researches demonstrated that multi-classifier is an effective approach to improve the classification performance of CAD system. In this paper, we present a new hybrid classifier for mammographic CAD by hybridizing Logistic Regression (LR) and K-nearest neighbor (KNN) classifiers. To test and evaluate the proposed hybrid classifier, several experiments were carried out. The experimental results show that the proposed hybrid method achieves better performance then those two single classifiers (i.e., LR classifier and KNN classifier).
