摘要：
In computational anatomy, statistical shape model is used for quantitative evaluation of the variations of an organ shape. Since liver cirrhosis will cause significant hepatic morphological changes, we applied statistical shape model of the liver to capture the morphological changes and recognize whether a liver is normal or abnormal. In this paper, we propose an effective mode selection method to improve the classification accuracy. In addition to the conventional Accumulated Variance Contribution Rate (AVCR) based mode selection, we newly propose a Pearson correlation based mode selection method and combine them to select the effective modes. The coefficients of the selected modes (components) are used as features to recognize whether liver is normal or abnormal. The effectiveness of the proposed method is evaluated by the classification accuracy of normal and abnormal. Experimental results show that our proposed method is superior than conventional methods.

摘要：
The vehicle body shaping determines car appearance and has an important impact on aerodynamic drag force and lift force, thereby it affects the performance dynamic and manipulation of the vehicle etc. This article established two kinds of vehicle design scheme, and carried out simulation CFD study on the two models using Fluent Software. The results show that the second scheme has smaller wind resistance coefficient and larger lift coefficient, which will be conducive to enhance the vehicle's power and improve fuel economy. The second scheme has lower pressure at the bottom of the engine than the first, although it has larger lift coefficient, which is beneficial to make up for the poor stability caused by the larger lift coefficient. By contrast of the two schemes, the wake vortex of first scheme is larger and close to the ground, which is easy to cause dust kicked up from road, the wake vortex of second scheme is smaller and keep a certain distance from the ground, which can avoid kicking up dust. Through comprehensive analysis, the second scheme is a better design.
摘要：
This paper focuses on the changes of mechanical properties of poplar wood after the microwave pretreatment with different microwave intensity and different irradiating time. The results show that the mechanical properties of poplar wood, such as the modulus of elasticity and the bending strength have decreased when the microwave pretreatment gets lower intensity and shorter irradiating time. But, with the higher microwave pretreatment intensity or longer irradiating time, the mechanical properties of poplar wood has been improved, which is arising from the release of growth stress of poplar wood. After the microwave pretreatment, something have been changed in microstructure of poplar wood, such as the formation of tiny cracks and the membranes rupture, those are contributed to release the growth stress of poplar wood, thereby improve the mechanical properties.

摘要：
The analysis of tourist flows behavior can help to achieve the reasonable allocation of social resources for tourist area and respond effectively to the tourist destination traffic pressure, maintain social public security, etc. The traditional manual analysis methods, such as questionnaire survey, have the characters of the high cost and low efficiency. With the development and popularity of smart phones in the daily life, on the one hand, it brings convenience for people. On the other hand, the user mobile trajectory data provides the effective analysis of tourist flows behavior. This paper presents a framework for the analysis of the distributed tourist flows, and uses the multi-node processing tasks, thus to improve the performance and scalability of the algorithm. It takes advantage of the mobile track data provided by the mobile phone operators to analyze the tourist flows, and establish several models, including the vacation destination's tourist flows behavior analysis model and habitual residence's tourists analysis model. Compared with the traditional methods, this scheme has lower cost, higher efficiency and wider coverage.

heterogeneous small cell networks;energy efficiency;coverage performance;nodes deployment optimization
摘要：
Various types of small cell base stations (SBSs) are deployed randomly in heterogeneous small cell network to meet the soaring growth in traffic, which leads to more and more complex network topological structure and resource management. In this paper, we analyze the coverage performance and energy efficiency of a two tier heterogeneous network which is composed of micro tier and pico tier. With the aid of stochastic geometry tools and PPP properties, the analytical expression of success probability for each tier is derived to evaluate the tier's coverage performance how to vary with the SBS deployment density. In addition, the energy efficiency optimization question is formulated in terms of the resource allocation fairness proposed in this paper. Base on the analytical results, numerical simulations show that the effects that the SBS deployment density has on the coverage performance and energy efficiency and confirms that there exits an optimal SBS density ratio among the two tier which can be applied to maximize the energy efficiency.

Small cells;hierarchical clustering;non-cooperative game;correlated equilibrium
摘要：
In this paper, we investigate the hierarchical clustering for dense small cells and devise non-cooperative game-theoretic scheme, with aim at increasing the network throughput and minimizing both cross- and co-tier interference. By studying the distances between the small cells and the requirements of cluster formation, we propose a novel hierarchical clustering scheme for the densely deployed small cells, which consists of two phases, i) an absorption mechanism is designed to form the small cells into clusters; ii) to balance cluster populations, a segmentation algorithm is proposed for the clusters that contains excessive small cells. Within each small cell cluster, the spectrum is split into central frequency and marginal frequency which can be reused in a FFR manner. Then, we formulate the spectrum allocation and interference mitigation issues as a non-cooperative game, in which a game theoretical strategy optimization algorithm based on regret-matching is proposed to reach the correlated equilibrium. Numerical results reveal that our approach can achieve the correlated equilibrium with fast convergence and it is effective in offloading traffic and increasing the system throughput in dense small cell networks.
摘要：
With the worldwide research on natural product activity, new technologies and methods have been added to the screening of natural products. This effectively improves the efficiency and precision of the screening of the active ingredients of natural products. Artificial intelligence is a new technology which is currently in the field of computer, the basic principle of artificial intelligence technology was applied to the screening of active components of natural products in the paper, which has laid a solid theoretical foundation and support for strong screening active components in natural products. Different from the previous research methods, the method based on artificial intelligence not only promotes the role of biological activity, but also effectively shortens the time of discovery of active compounds[1]. The modern intelligent algorithm used in this article, and the full algorithm of support vector machine (SVM) classification performance and excellent precision of the genetic algorithm (GA) with high robustness of the comprehensive, premise analysis of the active components of natural products in quantity, build the basic framework of intelligent quantitative evaluation. We combined with the actual situation to verify the practicality of the mode in the subsequent learning process, which confirmed the feasibility of the model, to provide a basis and reference for the subsequent chemical treatment of natural products.

摘要：
There are lots of uncertainties in variable-stiffness composite materials such as material properties, fibre volume fraction, geometries at various scale and matrix porosity. Commonly, these uncertainties are not always mutually independent and there exist correlations among these random input variables. These correlations may affect the output of composite significantly. To address these correlations, a novel approach for uncertainty analysis based on copula function assisted by reanalysis method is suggested. The Copula function is utilized to address the correlations of random input variables. Monte Carlo simulation (MCS) is employed to obtain the uncertainty analysis. Therefore, a large number of samples should be generated and the expensive computational cost is not feasible when the popular finite element (FE) model is utilized. To save the computational cost and make the uncertainty analysis feasible in practice, an efficient fast computation method, reanalysis method is integrated in the frame. The numerical test demonstrates that the proposed approach is an efficient uncertainty analysis tool for the practical engineering problems.

Ancient books;Folding case;Preservation;Acid-Free Paper
摘要：
In order to deal with the acidification problem which mainly influences the life of ancient Chinese books preserved in many libraries and museums, to employ folding cases can directly protect them apart from the other conservation measures such as the environment control technology and restoration technology of the ancient books. Most traditional folding cases are made of the straw cardboard which is short-life, easy-moth, easy-mildew and acidified gradually. Compared with the traditional material, the new type acid-free paper bears an outstanding advantage in terms of durability and protecting environment. Analyzing the forms of the folding cases and their cultural connections with the ancient books, this paper made a conclusion that using acid-free paper folding cases by machine with the traditional Four Sets form is an effective and efficient way to conserve ancient books due to the perfect combination of the acid-free material and the classical folding case form.

In this way, it can realize the effective detection for management procedure, which sets a foundation for the future intelligent forest management schemes in forest farm level.
摘要：
Although anti-phishing solutions were highly publicized, phishing attack has been still an important serious problem. In this paper, a novel phishing webpage detecting algorithm using the webpage noise and n-gram was proposed. Firstly, the phishing webpage detecting algorithm extracts the webpage noise from suspicious websites, and then expresses it as a feature vector by using n-gram. Lastly, the similarity of feature vector between the protected website and suspicious is calculated. Experimental results on detecting phishing sites samples data show that: this algorithm is more effective, accurate and quick than existing algorithms to detect whether a site is a phishing website.
