New Vacuum Solar Telescope (NVST) possesses a world-class solar telescope which observes the sun by high resolution image instruments and multi-wave spectrometer in visible and near infrared bands. NVST has gathered millions of Flexible Image Transport System (FITS) files since it has been for the routine observation and thousands of files are generated in a day. To search efficiently for a subset...
This paper presents a study of regional effect on incubator function of innovation cluster from the perspective of knowledge management. First, the concept of Regional Incubator Function is defined. The reasons of both the birth and the development of the Regional Incubator and the effect of promotion of knowledge spillover are analyzed. Second, factors of the influence of the knowledge spillover...
Stock market is an important and active part of nowadays financial markets. Stock time series volatility analysis is regarded as one of the most challenging time series forecasting due to the hard-to-predict volatility observed in worldwide stock markets. In this paper we argue that the stock market state is dynamic and invisible but it will be influenced by some visible stock market information....
The paper researches the land use investigation by using aerial photography which obtained by the high resolution CCD. It discusses the method to interpret land use in Liugou of Penglai and use the parallel relation between digital orthophoto(DOM) and features to analyze the condition of land use with with 3S technology to expression in detail. It will provide scientific and necessary references to...
Intrusion Detection System (IDS) is the key technology to ensure the security of dynamic systems. We employ a sequential pattern mining approach to discover significant system call sequences to prevent malicious attacks. To reduce the computing time of generating meaningful rules, we design a weighted suffix tree structure to detect intrusive events on the fly. The experimental results show our method...
With the increasing popularity of Internet and the diversity of information obtaining technologies, the amount of quickly growing information has gone beyond our imaginations. Many techniques were presented to help users to find the desired information from large data set quickly and accurately, automatic summarization is an effective approach. In this paper, after careful investigation, existing...
According to mapping relationship of the relative internal efficiency of low pressure cylinder of condensing steam turbine and its affection, a mathematical model based on the Immune system's wavelet network was established. It can be used for calculating the relative internal efficiency of low pressure cylinder of 300 MW steam turbine. The application of the model shows that the proposed method is...
In this paper, we consider the application of near-MDS codes in cryptography. Near-MDS codes have some important properties that can be used to construct secret sharing schemes. The proposed secret sharing schemes in this paper have good security properties such as cheating detection and cheaters identification when recovering the secret. In addition, the number of participants in our proposed scheme...
Fingerprint classification is crucial to reduce the processing time in a large-scale database. In this paper a fingerprint classification based on continuous orientation field and singular points is proposed. The continuous orientation field can not only filter the noises in point directional image, but also represent the basic structural feature of fingerprint more precisely. Singularities are the...
Ultra wide-band (UWB) communication has to face two problems of multi-access interference (MAI) under multiple access scenario and intersymbol interference (ISI) in multipath environment. In this paper, we proposed a blind adaptive multiuser detection algorithm for direct-sequence code division multiple access (DS-CDMA) UWB systems in ISI channel, called two-stage algorithm, which consists of two...
The data structure diagram is abstracted from the diagram of railway yard signal arrangement. HBACA (hybrid behavior based ant colony algorithm) is presented to search the shortest route of railway yard. The route searching program based on HBACA is developed. The graphical representation of railway yard is given on the console. According to the designated beginning node and the designated ending...
Enterprises must realize the change from seller market to buyer market which forces enterprises to produce consumer-oriented products under environment of the needs of customers individuality and the ever-changing market, thus adopt the customer-centered supply chain managing thought. Competition among enterprises is the competition among the supply chains, and the competition advantage of supply...
In view of complexity of the construction engineering quality and fuzziness of quality evaluation, AHP-based multi-level fuzzy comprehensive evaluation become the advantage model for construction engineering quality assessment. The core computing of Fuzzy Evaluation is the membership conversion; however, membership conversion way at present has a problem of redundancy. Because of this, we use entropy-based...
Three parallelization approaches used in the program of discharge simulation along resin insulator surfaces in SF6/N2 gas mixture which initially consumes a great deal of computational time and suitable for implementation on computer systems with symmetric multiprocessor (SMP) architecture are developed and validated in this paper. The approaches include: (i) static domain decomposition using a distributed...
Due to the growing use of mobile video services, monitoring of perceived video quality in live systems becomes of high interest. For this purpose, it is required to capture video quality consistent with the principles behind the operation of the human visual system and to accommodate some suitable quality reference to the transmission of the mobile video service. This can be achieved by extracting...
Because of the impact of financial crisis, it is difficulty for Chinese small and medium-sized real estate enterprises to finance. By the real estate syndicate financing from abroad combined with the reality of our country, this article puts forward Chinese real estate syndicate financing methods, and uses game theory to analyze and study it. Study shows that the mode of financing of real estate syndicate...
This paper explains some of the ideals and characters about PLE (personal learning environment). And introduce web2.0 social software and technology to construct PLE, where there is the difficulty for learners to integrate these dispersive tools and technologies. So it proposes a framework for an open source Personal Learning Environment which is called PLEF. The emphasis is on the process to build...
To solve the problem which is hard to avoid the local optimal solution or slower population diversity when using genetic algorithm to generate the fuzzy rules in a fuzzy system, this paper proposes an automatic rule generation using fuzzy genetic algorithm. This algorithm utilizes the rules population diversity and evolutionary speed to automatically adjust the crossover rate and mutation rate based...
In this paper, we proposed a new approach which employed the selfish gene theory to construct virtual population for optimizations. And an incremental learning scheme which based on mutual information entropy was also used to speed up the convergence velocity. Experimental results on several benchmark problems show that, this new approach often performs better than BMDA, COMIT and MIMIC.
Computer games are today an important part of most children's leisure lives and a growing part of our culture and learning. Educational games can make a good combination of games and education, and try to support children's learning through playing games to realize happy study. RPG educational game is an important type of games in today's school teaching, because of its virtual experience environment...
