Abstract: With the development of the Internet, the online shopping was increasingly into people's life. In order to provide convenient search and price comparison service for shopping online, this article designs and implements automatic search and comparison system based on Deep web. To overcome the difficulties of data capture from the current dynamic webpage, the background’s data capture of this system implements by watir. The search module for end-users implements by JavaEE. The practical application shows that this system can fully satisfy people’s needs in search and comparison.

Abstract: The paper proposed a novel methods of Software Architecture Based on the UML and B methods in order to solve the aspects of the architecture of the Statute strengths and weaknesses of existing language software architecture. By the defined rules will be relatively independent of each other sub-components or connections to the executable code refinement. Finally, a concrete example to verify the feasibility of the method. The method is entirely possible refinement in the software architecture, the process of implementation, both retained the use of a systematic analysis of UML design system modeling capabilities and powerful object-oriented model of clear and concise notation, but also against the software model can be formalized The refinement process of validation, the combination of these two methods found a good balance point, making software architecture allows us to design the same time, the architecture design can ensure the consistency and reliability.

Abstract: A novel edge-based active contour model (ACM) is proposed in this paper. Our edge-based active contour model has many advantages over the conventional active contour models. Firstly, the proposed model can get much smoother contour and needs much less iterations to evolution by being implemented with a special processing named Selectively Binary and Gaussian Filtering Regularized Level Set (SBGFRLS) method. Secondly, we introduce Bilateral Gaussian Filter which can preserve edges to smooth images. So we make weak edges more clear than traditional Gaussian Filter. Thirdly, the level set function can be easily initialized with binary function, which is more efficient to construct than the widely used signed distance function (SDF) because of the special processing. Experiments on synthetic image and segmenting liver from abdominal CT images demonstrate the advantages of the proposed method over geodesic active contours (GAC) in term of both efficiency and accuracy.

Abstract: Profibus and CAN bus are two kinds of widely used field bus in the industrial control field. However, this two bus protocol conversion devices are not introduced on the market, it can not meet the needs of users. Therefore, the design of a Profibus and CAN protocol translation ngateway is very important. By comparing the OSI reference model, the same points of Profibus and CAN bus can be found, their communication model structure is streamlined by the OSI model, they are only three layers, which makes it possible to interconnect them. This paper designs an embedded protocol conversion gateway, S3C2410 processor is used as main controller, SPC3 and SJA1000 are selected as Profibus and CAN protocol chips. The design has realized Profibus and CAN bus protocol conversion, using this gateway in industrial field can bring certain economic benefits for the enterprise.

Abstract: Component-Based Software Development is widely used in the software development, which focus on component composition and reutilization, but some problems such as compatibility and consistency always impact on component composition. Thus, we proposed a pipeline approach for component composition, which establish pipeline management mechanisms included different workshop section, workshop , monitoring and coordination, then ontology is interposed different workshop to implement component composition. Finally, it is analyzed by application example to show that the approach is feasible.

Abstract: Intellectual capital is the capital form of the modern corporation core competence. The authors analyzed and discussed the formation of core competence of corporation by using balanced score card. Besides that, this issue evaluated the core competence of corporation based on the combination of analytic hierarchy process and fuzzy comprehensive evaluation.

Abstract: In the progress of fault diagnosis, the most difficult problem is how to build up the fault swatchs for diagnosis for the fault of reciprocating compressor. As for the working progress mathematic model of reciprocating compressor, some familiar faults are simulated in this paper. The method of building fault swatches of the Z-0.03/7 compressor is studied and tested. Using the fault swatches, the fault diagnosis of compressor has been carried on.

Abstract: Sustainable development and nano-materials is the focus of widespread concern in today's world. Nano-material not only is the main way of material development, but also is closely related to requirement of sustainable development. This paper states the influences of disseminating nano-materials to sustainable development and the traditional system of accounting scientifically, these influences include form of conception of sustainable development, establishment of value system of natural resource and introducing the evaluation system based on data of accounting for enterprises. The aim of these researchs will be references for evaluating the economic effectiveness of resources invested in disseminating nano-materials.

Abstract: Most watermarking schemes in literatures are usually implemented by embedding a mark in a host media itself for intended purposes. The existing techniques for watermarking are confronted with the problems of perceptible quality degradation and the inherent conflict between imperceptibility and robustness, which introduced by the watermark embedding. In this paper, we propose a novel audio zero-watermarking scheme for content authentication. First the audio is divided to frame by fixed length and then low-frequent and high-frequent components are obtained by three-level lifting-based wavelet transformation in every frame. Secondly the audio frame is approximately represented as a product of a base matrix and a coefficient matrix using non-negative matrix factorization (NMF). Finally the sum of each column in the coefficient matrix is calculated which is quantized to produce a feature vector, and then the copyright information is obtained by calculating the watermark and feature vector. Experiment results show that the proposed scheme is robust against Mp3 compression and secure.

Abstract: Ontology mapping is a crucial task to enable interoperation and interoperability between related ontologies. Combining multiple mapping strategies can improve the mapping accuracy in ontology mapping. However, how to give weight values in multiple strategy ontology mapping is very difficult. Aiming at the problem, characteristics based adaptive weighting method is proposed in the paper. Six similarities is selected to reflect different kinds of ontological information. Ontologies characteristics related to the six similarities, which include self-characteristics and mutual-characteristics of both ontologies, are used to describe both ontologies to be mapped. Weight of each similarity is specified according to the characteristics of both ontologies. Experiment results showed that the method in the paper can get a better effect than traditional weights combining methods.
