2012 November 11th, on the background of bleak retail industry and harsh electrical environment, Taobao and Tmall achieved 19.1 billion's turnover within 1 day, and most of the share were contributed by those small and medium-size brands as well as Tao-brands.Why those undistinguished ordinary small brands and Tao-brand could obtain such an impressive achievement? In this paper, the author reflects on this phenomenon and finds that the reasons are mixed, including: (a) the risks of shopping online; (b) the innovation sales mode employed by Taobao and Tmall; (c) low cost interactive between businesses and customer; (d) the amplification effect of network; (e) Alibaba platform is mature and stable; (f) the platform is a combination of diversification and specialization. Furthermore, the author also points out four main problems emerge in this phenomenon. © Springer-Verlag Berlin Heidelberg 2013.

The teaching design of resource-based collaborative learning, as a teaching strategy, is on the basis of relevant theories of educational technology, and confirms reasonable teaching resources and knowledge by analyzing learning contents and teaching objectives so that collaborative learning can be put into effect depended on all kinds of collaborative means and interactive mode and learning effect is also improved. On the basis of relevant theories of resource-based collaborative learning, this paper takes the example of "Purchasing Management" course in vocational high school, and elaborates the teaching design process of resource-based collaborative learning in detail from four steps, that is frontend analysis, detailed design, learning process, and effectiveness evaluation and so on. The teaching practice has acquired well effect and it will offer important references for transformation and practice of education of vocational high school in China. © 2013 Springer-Verlag Berlin Heidelberg.

Ontology is a philosophical concept originally,which describes the natures of objects. Because there is not a common criterion for building ontology, a lot of heterogeneous ontologies are constructed in the same domain.Ontology mapping is an effective method to realize the interoperation of heterogeneous ontology. The key of ontology mapping is to calculate similarities between concepts. In this paper, we propose a multi-strategy ontology mapping method. The concept similarity is computed from the aspects of concept name, concept attribute and concept relationship. What's more, the candidate set and information gain are brought to improve the accuracy of similarity and to simplify the calculation process. Extensive simulations show that the approach is an effective algorithm and better than others. © 2011 IEEE.

In the scenario of database outsourcing, database management is outsourced to the professional third-party, and one of the critical problems is integrity authentication of the query results. As far as we are concerned, we are the first to propose the problem of outsourced append-only database. According to the features of outsourced append-only database, a new authentication data structure, Min-Max Hash tree is proposed based on the current authentication data structure. It can be utilized by the clients to solve the problem of authenticating the query results. For the data owner side, a basic data forwarding algorithm is proposed; and for the service provider side, the algorithm of querying rise, fall or oscillation amplitude in price and the algorithm of query results authentication are proposed respectively for one-shot query and continuous query. Finally, optimization measures are proposed for data forwarding, storage of authenticated data structure in the data owner side and continuous query in the service provider side, by which the space of storage is diminished greatly and the whole efficiency of data processing is improved further. Extensive experiments have demonstrated the effectiveness and efficiency of the proposed Min-Max Hash tree. It can be utilized to authenticate the query results and to process the massive data.

Empirical Mode Decomposition (EMD), the core of Hilbert-Huang transformation, is reckoned on the algorithm of the extrama extending and generation of envelope curves. A novel EMD algorithm was proposed based on reproducing kernels with good local property such as odd order vanishing moments, rapid attenuation of scaling, symmetry and regularity. At last, simulations on two non-stationary signals show the novel EMD algorithm is suitable to analyze the nonlinear and non-stationary signal.
