Euler-Bernoulli beam theory was used to model the beam while Winkler foundation model was used for the foundation. The beam of length l was assumed to be simply supported at the ends x = 0, and x = l. The PDE was decoupled by the assumption of harmonic vibration. Application of the finite Fourier sine integral transformation on the decoupled equation resulted in the transformation of the problem to an algebraic eigenvalue problem. The condition for non-trivial solutions resulted to the characteristic frequency equation which was expressed in terms of a non-dimensional frequency parameter . n  The frequency equation which was observed to be the exact frequency equation obtained in the literature using the Navier series method, was solved to obtain the non-dimensional frequencies. Numerical values of the non-dimensional frequencies were computed for the case where 4 4 1,  = l = 1, and for n = 1, 2, 3, 4, 5. It was found that exact values of the non-dimensional frequencies were obtained using the present method.","PeriodicalId":306244,"journal":{"name":"International Journal of Darshan Institute on Engineering Research & Emerging Technology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132431447","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}

Currently, a majority of web portals offer their searching utilities, be it better or worse. These can search for the content within the sites, mainly text the textual content of documents. In this paper a novel similarity measure called SMDR (Similarity Measure for Documents Retrieval) is proposed to help retrieve more similar documents from the repository thus contributing considerably to the effectiveness of Web Information Retrieval (WIR) process. Bio-inspired PSO methodology is used with the intent to reduce the response time of the system and optimizes WIR process, hence contributes to the efficiency of the system. This paper also demonstrates a comparative study of the proposed system with the existing method in terms of accuracy, sensitivity, F-measure and specificity. Finally, extensive experiments are conducted on CACM collections. Better precision-recall rates are achieved than the existing system. Experimental results demonstrate the effectiveness and efficiency of the proposed system.","PeriodicalId":306244,"journal":{"name":"International Journal of Darshan Institute on Engineering Research & Emerging Technology","volume":"6 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":"123091114","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}
