But in recent years, over-deflection of beam in this bridge has become an serious problem. This may cause the redistribution of displacement and internal force of the whole structure, especially in dynamic load status. A twodimensional pile-soil-bridge model is built up in ANSYS based on a factual bridge. The over-deflection is considered as the decrease of beam elastic modulus. The displacement and internal force of key parts are analysed in static and dynamic vehicle load. The study shows that over-deflection will reduce the first three natural vibration frequency, weaken the sensitivity of bridge to dynamic load. In dynamic load status, the displacement and internal force will be influenced by rigidity of beam.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125272323","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 extremely challenging to locate and recognize barcodes when the background is cluttered and the illumination is uneven. In this paper, we propose a hierarchical framework for 2D Data Matrix recognition and further introduce the 2D barcode recognition system based on the proposed method. The superiority of this framework lies in three folds: 1) it is robust to unbalancing illumination, geometric deformations and affine transform; 2) barcode region localization is performed to make the system robust to clutter background and to save computation complexity; 3) the floating DSP hardware platform guarantees the decoding accuracy and speed to attain a leading level. The large-scale experiment shows that the proposed framework can achieve high accuracy and robustness for 2D Data Matrix recognition and has been transferred into real production.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122500161","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 paper used the Fuzzy Comprehensive Evaluation Model based on Analytic Hierarchy Process which integrated the advantages of both Fuzzy Comprehensive Evaluation and AHP. Based on the Fuzzy Theory, some evaluation factors that are difficult to quantify and whose boundaries are unclear have been quantified. In actual evaluations, Delphi Method is used to quantify the qualitative factors. The establishment of the criteria weight sets uses AHP. According to the principal of the forewarning system, the evaluation criteria system was established. Finally, an illustration is given to show how this method works. The result shows that Fuzzy comprehensive evaluation based on AHP is an effective method to evaluate the safety condition of a freeway system in the freeway traffic accidents forewarning system.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122568991","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}
