Recently, novel microbolometers composing of two planes located at different levels were proposed to improve the performance of the detectors. In this paper, such two-layer microbolometers were simulated by finite element analysis. Results reveal that when SiO2 film is utilized as the isolating and supporting material located at the lower bridge plane, the temperature rise of the pixel reaches 3∼5 times higher than those in the conventional one-layer microbolometers, and the maximum IR absorptance increases for about 40%. Therefore, these two-layer microbolometers are helpful for significantly improving the thermal and optical properties. However, their structural stability turns poor. Consequently, the mechanical properties for such two-layer microbolometers should be enhanced in practical applications.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"80 1","pages":"745-747"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86237588","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}

Both optimum subset regression (OSR) and analogue method are used to advance the model prediction on ‘bad modes’. Results suggest that the prediction ability of the mode accounting for less variance may be higher than the mode with more variance. The OSR failed, while the analogue method based on OSR shows a possibility of improving the prediction techniques by correcting the bad modes of model. However, since the model has a poor capability in representing the second and third EOF modes of the observation which account for a large percentage of the total variance, the forecast ability can not be improved effectively where the model prediction information is not enough or incorrect. So it is necessary to make a further analysis on the samples of the ‘bad modes’ and the corresponding external forcing which might better realize the correction for such ‘bad modes’.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"66 1","pages":"1367-1370"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90729798","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 paper proposes the space intersection formula for the new method that is used for stereo positioning. The vertical parallax is cleaned between the stereo images by using the new method and the horizontal parallax is preserved or increased.

A fast placement and global routing integrated algorithm for hierarchical FPGAs 分层fpga的快速布局和全局路由集成算法

While it simplifies design modelling and algorithm implementation, some problems such as mismatches between the two will also occur when a valid placed circuit can't be globally routed. The mismatches can significant increase the overall runtime of the physical design. A new placement and global routing integrated algorithm is proposed in order to reduce these mismatches. By immediately applying a global routing feedback to each placement step, the invalid placement step can be found and re-placed. Finally, a valid placed, globally routed circuit is obtained ready for the following detailed routing. This algorithm also takes advantages of the architectural features of the new hierarchical FPGAs and employs clustering at each placement step. As the clustering algorithm is hierarchical in its essence, it is very similar with the FPGA in structure. As a result, the proposed algorithm is very fast in runtime due to all these facts. The experimental results show that a very large circuit can be placed and globally routed very quickly in just a few seconds.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"1 1","pages":"52-57"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88465239","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}
