China amateur basketball open tournament have suffered the effect of globalization and developed in an all-round and rapid way in recent years, the paper studies Chinese CBO current situations to further analyze the development of Chinese sports culture. The paper makes statistics directed at the investigation result of famous experts, scholars, amateur basketball enthusiasts, finds that total number of people in visited experts is 128; professors account for around 20%, the credibility is very high. And meanwhile, make statistics of randomly released questionnaire and recovery situations; the recovery rate is 100% that proves the universality of investigation group this time. Analyze situations of amateur basketball participants, get that workers account for 30% of Chinese amateur basketball participants. Utilize adaptive filtering approach and correlation analysis method to predict the number of people in Chinese amateur basketball clubs from 2015 to 2019, carry out repeatedly analysis and calculation on historical observed data through the approach of weight number adjustment, and get optimum weight number.

Tb3+-doped LaPO4 microfibers were synthesized via electrospinning, using La2O3, Tb2O3, NH4H2PO4 and PAN as starting materials. The structure and morphology of the resulting products were characterized by XRD, SEM, TEM, FT-IR, TG-DTA and XPS, while the luminescent properties of the products were investigated by fluorescence spectrometer. The results indicated that the as-prepared products were crystallized in pure body centered tetragonal LaPO4 phase with uniform fibers morphologies and the sizes of the samples were estimated to be around 150 nm. XRD patterns of the as-fabricated Tb3+-doped LaPO4 microfibers showed that Tb3+ was doped at Tb3+ sites in LaPO4 crystal. There was no emission peak of PO4 3- from fluorescence spectrum of LaPO4: Tb microfibers, which indicates that LaPO4 is a very attractive luminescent host. The electrospinning is convenient and easy, and the as-prepared LaPO4: Tb microfibers show strong and stable fluorescent intensity.

As it is of great importance to extract useful information from heterogeneous Web data, in this paper, we propose a novel heterogeneous Web data extraction algorithm using a modified hidden conditional random fields model. Considering the traditional linear chain based conditional random fields can not effectively solve the problem of complex and heterogeneous Web data extraction, we modify the standard hidden conditional random fields in three aspects, which are 1) Using the hidden Markov model to calculate the hidden variables, 2) Modifying the standard hidden conditional random fields through two stages. In the first stage, each training data sequence is learned using hidden Markov model, and then implicit variables can be visible. In the second stage, parameters can be learned for a given sequence. (3) The objective functions of hidden conditional random fields are revised, and the heterogeneous Web data are extracted by maximizing the posterior probability of the modified hidden conditional random fields. Finally, experiments are conducted to make performance evaluation on two standard datasets-"EData dataset and Research Papers dataset". Compared with the existing Web data extraction methods, it can be seen that the proposed algorithm can extract useful information from heterogeneous Web data effectively and efficiently. © 2014 ACADEMY PUBLISHER.

For the shortcomings of traditional network security alarm correlation method, combined with the original alarm information privacy protection needs. On the basis of analyzing the characteristics of multi-step attack, proposed the use of sequential pattern mining techniques associated with rapid multi-step attack methods QSPM. And on this basis, proposed privacy protection security alarm multistep attack sequence pattern mining method PPSPM, Achieve the associated sequence of events following the invasion premise security. Experiments show that the algorithm makes quantitative analysis. And compared with typical sequential pattern mining algorithm. Results show the new methods have a positive accuracy and efficiency. © 2014 SERSC.

Aiming at the low limitation of shilling attack detection technology unsupervised degree, this paper takes the group effect attack profile as the breakthrough point to construct the attack profile groups and the corresponding genetic optimization objective function of quantitative measure of the effects, and prove that the maximum value of the objective function in the ideal state marks the optimum detection effects in ideal situation. On this basis, the combination of genetic optimization process will be adaptive parameter posterior inference and objective function, and proposes the Iterative Bayesian Inference Genetic Detection Algorithm (IBIGDA).Experimental results show that IBIGDA can effectively detect shilling attacks of typical types even in lack of the system or attack-related prior parameters. IBIGDA algorithm can detect common shilling attack, unsupervised degree is high, with the actual application requirements. © 2014 SERSC.

In many sports, tennis occupies an important position. For a tennis player, it is an important factor in a good pair of tennis to win the game. The composite materials in the production process in tennis racket are studies in this paper. Analyzed and demonstrated several ways from its function and structure, process performance, process and process analysis. Finally, the production process of the racket will be detailed study, and then a conclusion will be get that is composite material has important practical value in the production of a tennis racket. © (2014) Trans Tech Publications, Switzerland.

In this paper, we take the urban road network as the object, a further study on the method of traffic signal self organization under the condition of traffic state identification and local congestion. In the urban road traffic state identification study, according to the need of traffic signal control, respectively from qualitative and quantitative point of view, the urban road traffic state is defined. In order to be able to obtain real-time traffic data as the foundation, design urban road traffic state evaluation index system. Based on the current mainstream micro traffic simulation software VB and VISSIM as the tool to build the experimental platform, and set up the UTC-CI (Urban Traffic Control for Congested Intersections) experimental environment, the above method is verified by simulation. The results show that the traffic state identification method and the related signal control method have the expected effect in reducing congestion duration.
