With more than 16 years usage of RTCA DO-178B, the standard has been widely accepted in the industry, and the reality shows that its effect in aviation safety is acceptable. While besides this generic means, from time to time other means have been sought to substitute DO-178B. The paper discussed several means and methods for software certification compliance with the feasibility thereof, and made comparison between them.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129355495","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}

Therefore, a kind of telescopic triangular fuzzy sets was studied, it can changes the division of fuzzy sets non-uniformly by adjusting the stretching factor, and substantially reduces the number of the rules in the same input range. Based on the fuzzy sets, a fuzzy controller was constructed to calculate the Web request load for the loadbalancing of Web server cluster.

The proposed algebraic decoding algorithm for decoding the (31, 16, 7) QR code with reducible generator polynomial is able to correct up to three errors in the finite field GF(25). The proposed algorithm is based on an application of the decoding algorithm given by Truong et al. and Chen et al. to modify the decoding algorithm proposed by Reed et al. All syndromes in the error-locator polynomial are computed in the finite field GF(25). Thus, the decoding time can be reduced. Moreover, the simulation results for comparing the proposed decoding algorithm with decoding algorithm given by Reed et al. are given.
