In this paper, Web content transcoding mechanism \"on-the-flight\" is presented. This mechanism works by means of a simple inclusion of a HTTP header named X-Transform, which describes a transcoding format command. This header is generated by a client-side proxy named GAP, which runs on mobile devices with Windows CE operating system (Pocket PC, Smartphone, among others). The transcoding header is interpreted by a server-side proxy named GAT MT, that converts Web documents to WML, XHTML-MP, PDF, plain text, PostScript, XML and HTML adapted for mobile devices, making use of XSL technologies (XSLT and XSL-FO)","PeriodicalId":432491,"journal":{"name":"2006 Seventh Mexican International Conference on Computer Science","volume":"97 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116801138","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}

One important aspect of the security scheme is about using encryption to protect sensitive information while it remains stored in the database. We first review in this paper the general aspects of data security and analyze how the leading commercial databases address these issues. Then we discuss about applying encryption as a justified measure of increasing the data privacy and we identify a weak support from commercial database systems when a group of users owns encrypted data. Finally, we propose an enhanced mechanism, called secure groups, that intends to improve the management of encryption at a database level","PeriodicalId":432491,"journal":{"name":"2006 Seventh Mexican International Conference on Computer Science","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133874389","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}

The phase field equation is used to model a two-phase fluid inside a tube, where the boundary conditions at the walls define the static contact angle. The numerical solution is found by the finite element method with triangular elements, using a structured mesh generated with Delaunay triangulation. First, the adaptive grid algorithm is carefully tested in an analytic function where numerical results demonstrate the accuracy and effectiveness in the adaptive grid generation. Finally, we present numerical results for the phase field model","PeriodicalId":432491,"journal":{"name":"2006 Seventh Mexican International Conference on Computer Science","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124340761","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}

This mechanism is based on local-perception and low-level communication. It is oriented to coordinate situated modular robots. The swing propagation mechanism is divided into two movements: simple following and collective obstacle-avoidance. The first movement is executed when the leader of a robot formation is able to move and proposes a movement that is copied by its followers in the formation. The second movement is executed when the leader of a robot formation is unable to move and asks its followers to undo an action. In the first movement, motion is propagated backwards in a robot formation, whereas in the second movement, a request is propagated backwards and motion is propagated forward in a robot formation. Experimental results of multi-robot motion coordination using Mini-trans, a physical homemade modular system, are presented","PeriodicalId":432491,"journal":{"name":"2006 Seventh Mexican International Conference on Computer Science","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115924898","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}
