The proposed method is applicable for α ∈ (0, 1], where α denotes the order of the fractional derivative in the Caputo sense. Convergence analysis of the method is considered. Some illustrative examples are presented and the obtained results reveal that the proposed technique is very effective, convenient and quite accurate to such considered problems. The study is conducted through illustrative examples and error analysis. keywords: Fractional integral and derivative, Caputo Derivative, Taylor’s expansion, Error bound, Spline functions. 68 Faraidun K.

The first objective is the minimization of the end to end delay; the second objective is maximization of the energy efficiency of the network depending on packets payload size.

The statement is popularly known as Fermat’s last theorem. An acceptable mathematical proof of this theorem is being explored still today. When searched online treasures of resources, one may find various proofs of this theorem. In this paper I am not discussing any historical attempts that failed or partially succeeded. I am going to discuss the approach which I have adopted to proof this theorem. The approach is based on odd-even classification of positive integers. Assumption that the equation x n + y n = z n , where n, x, y and z are all positive integers, has a solution for n > 2 leads to some contradiction.","PeriodicalId":210748,"journal":{"name":"International Journal of Open Problems in Computer Science and Mathematics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124263983","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}
