Research ArticleOpen accessIn the abstractSingle Pass Seed Selection Algorithm for k-MeansK. Karteeka Pavan, Allam Appa Rao, A.V. Dattatreya Rao, G. R. SridharProblem statement: The k-means method is one of the most widely used clustering techniques for various applications. However, the k-means often converges to local optimum and the result depends on the initial seeds. Inappropriate choice of initial seeds may yield poor results. k-means++ is a way of initializing k-means by choosing initial seeds with specific probabilities. Due to the random … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractRanking of Simultaneous Equation Techniques to Small Sample Properties and Correlated Random DeviatesA. A. Adepoju, J. O. OlaomiProblem statement: All simultaneous equation estimation methods have some desirable asymptotic properties and these properties become effective in large samples. This study is relevant since samples available to researchers are mostly small in practice and are often plagued with the problem of mutual correlation between pairs of random deviates which is a violation of the assumption of mutual independence between … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 6,598 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Platform to Develop a Secure Instant Messaging Using Jabber ProtocolGhossoon M.W. Al-SaadoonProblem statement: Open Source technologies are interesting in that they allow free experimentation and integration by anyone and anywhere. A Jabber user can control presence with very little effort. Another user, regardless of external platform, must subscribe to your presence. You have the choice of rejecting or accepting the subscription at the time it is submitted. Approach: Other applications of … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrey-Catching Behaviour in Mudskippers and Toads: A Comparative AnalysisU. Kutschera, H. Burghagen, J. P. EwertThe invasion of land by a diverse group of fishlike amphibians during the Middle-Late Devonian was a key event in the history of life. It is obvious that the evolutionary transition from an aquatic to a terrestrial habitat was associated with physiological adaptations such as novel feeding strategies that can not be elucidated with fossils alone. Here we show that … …OnLine Journal of Biological Sciences, Vol. 8, Issue 2 · 30 Jun 2008 · 7,648 accessesView PDFCite
