As a result, the security defense of Enterprise Network Information System does not only include information system network security and data security, but also include the security of network business running on information system network, which is the confidentiality, integrity, continuity and real-time of network business. According to the security defense of Enterprise Network Information System, this paper proposes the \"network business security\" concept. In this paper, the object of information security is defined in three parts - - data security, network system security and network business security, and the network business security model is described. The proposal of the concept \"network business security\" provides theoretical basis for security defense of enterprise automatic production system and enterprise management information system.","PeriodicalId":269403,"journal":{"name":"2009 International Conference on Computer Technology and Development","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121036995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumer preference and perception of products strongly influence a product's acceptability. Both are expressed by words that may be studied using product semantics. As product semantics spreads rapidly in product design, it faces more interrogative challenges from the lack of empirical evidence to substantiate the claims of some product semanticists. Based on the study of product semantics design methods, this paper presents several principles which should be followed for expressing semantics in product design. Then, it explains the meanings of these principles by some examples. These principles should be helpful in product design.","PeriodicalId":269403,"journal":{"name":"2009 International Conference on Computer Technology and Development","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121067609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a spatial filter which operates in 2-stage 3x3 windows where the update value of the central pixel is a function of the median value of the pixels in the window. The proposed IDAF filter operates as follows. First, an impulse detection method classifies each pixel to be noisy pixel or image pixel. Then, if a pixel is assumed to be noisy, it is not used for deciding the new value of other pixels. A scheme is introduced to obtain a good replacement pixel value, which is then stored. The median of the stored values is a considered a good estimate of the image pixel. Finally, the adaptive fuzzy filter will then assign weights to the stored pixel values to produce the central pixel’s new value. Weights are assigned to remove impulse noise or preserve the image details, depending on the pixel’s characteristics. These characteristics are identified from the noisy image beforehand using a compatibility measure. The process detailed above enables the IDAF filter to remove impulse noise while preserving image details. Through testing, our experimental results show that the IDAF filter performs better than other standard median based methods.","PeriodicalId":269403,"journal":{"name":"2009 International Conference on Computer Technology and Development","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121113339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article a method is proposed based on the association rule mining which enables the computer to sense thoughts in a poker player's mind and guess his hand by observing his moves.

These structures are often augmented by formalisms which add a further dimension to the static description allowing for the modeling of the evolution of systems via any kind of transformation of such graphical structures. Graph transformation has been widely used for modeling. Graphs are well suited to describe the underlying structures of models. They provide a good method to carry out the analysis and verification activities and using the AGG toolset for designing them.
