They hope to find a method not only fast in speed but also high in accuracy. With the rapid development of computer technology today, computer numerical calculation, an important technology in scientific research, makes the comparisons among different complicated calculations possible. According to the calculation method, principle and levels of development of ¦Ð value, seven categories can be classified. Mathematical software would be used to analyze and compare the results of calculation through numerical simulation calculation of PI. Through the comparison between speed and precision, it can be seen that carol method is unstable and short of precision; the improved Ramanujan formula is the highest in precision and the fastest in speed of calculation, while Leibnitz series is totally reverse.","PeriodicalId":393655,"journal":{"name":"International Conference on Digital Manufacturing and Automation","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132793899","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}

Since the nodes with the highest degree are very susceptible to network congestion, we present an improved algorithm based on breadth-first search algorithm and high degree seeking algorithm. The current nodes transmit the query message to the neighbor nodes with the higher degree depending on their probability P of the nodes' degree. Our strategy can redistribute traffic load in central nodes to non-central nodes. The simulations are made on classical networks models and real networks. Our results indicate that the proposed search algorithm has better search results.","PeriodicalId":393655,"journal":{"name":"International Conference on Digital Manufacturing and Automation","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133781253","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 decrease of pressure will cause three areas, miscible flooding area, immiscible flooding area and transition area in reservoir (only miscible flooding area and immiscible flooding area are considered in this paper). At the same time, diffusion will be happen between CO2 and formation fluid. Base on the mass conservation and percolation theory, multi-phase, multi-component and division mathematical model was established. In this model, diffusion is considered in the process of miscible flooding and immiscible flooding. It is different from conventional mathematical model.

In this paper, Life Cycle Assessment (LCA) was applied in evaluation of the steel production process, analyzing the energy and materials consumption of Tangshan stainless steel industry in 2009. Based on inventory analysis, environment impact, global warming potential and human health influence were evaluated with three methods of Gabi4.3 software: EDIP, CML2001and Eco-indicator 99 (EI99). The results of LCA showed us that the high energy and pollution processes were iron-making, hot rolling and sintering, and the energy consumptions were 1166.22MJ, 837.92MJ and 633.45MJrespetively. Iron-making process was most harmful to environment and human health, so technological and managerial measures should be adopted to reduce the impact.","PeriodicalId":393655,"journal":{"name":"International Conference on Digital Manufacturing and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129182791","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}
