In the developed two-photon fabrication system, a single line with the width of 25μm and a 4mm×0.4mm plate were fabricated. The X-ray photoelectron spectrum reveals that the main element in the product is silver, and the range of resistivity from 10-3 to 10-5Ωm is calculated by measuring the resistance. The result shows that using two-photon induced reduction of metal ions, the reaction region can be controlled well, and it is helpful for the conductive metallic microstructure fabrication.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"1 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":"129262139","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 wide flammability limits allow hydrogen engine to be operated at extremely lean air–fuel ratios compared to conventional fuels. Concepts for part-load operation of hydrogen engines have been proposed using quantitative control and qualitative control. This paper summarizes the steady-state test results by quantitative and qualitative air-fuel ratio control modes in a hydrogen internal combustion four-cylinder engine operated on an engine dynamometer. Based on the test results of engine efficiency and NOx emissions, a combinated air-fuel ratio control strategy for hydrogen engine is proposed.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"106 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":"121527967","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 these systems, taxis are often used as probe cars. Because of the randomicity of taxis when travelling in cities, it is necessary to analyze taxis’ distribution characteristics in road networks. In this paper, two indexes named Detecting Intensity and Detecting Rate are designed to analyze the Space-Time Distribution Characteristics. 5,000 taxis in Hangzhou of China are selected as probe cars, and Floating Car Data are continuously collected from these taxis during a week. The conclusions show that Detecting Intensity and Detecting Rate can clearly demonstrate the Space-Time Distribution Characteristics in different time and road types. Urban express ways, arterial roads can usually be detected by probe cars with more dependability. Traffic conditions evaluated through FCD in peak hours on a day is probably more dependable than in off-peak hours. At the same time, the relationship between distribution characteristics and sample size are also analyzed, in order to help find a more reasonable probe car sample size for Real-time Transportation Information Systems.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"18 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":"122294250","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}

ECU calibration is done empirically through tests on the dynamometer (dyno) because no exact mathematical engine model is yet available. With an emerging nonlinear function estimation technique of Least squares support vector machines (LS-SVM), the approximate power performance model of a petrol engine can be determined by training the sample data acquired from the dyno. A novel incremental algorithm based on typical LS-SVM is proposed in this paper, so the power performance models built from the incremental LS-SVM can be updated whenever new training data arrives. With updating the models, the model accuracies can be continuously increased. The predicted results using the estimated models from the incremental LS-SVM are good agreement with the actual test results and with the almost same average accuracy of retraining the models from scratch, but the incremental algorithm can significantly shorten the model construction time when newtraining data arrives.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"49 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":"121718914","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}
