Research ArticleOpen accessIn the abstractDifferential Diagnosis Knowledge Building by Using CUC-C4.5 FrameworkKusrini, Sri Hartati, Retantyo Wardoyo, Agus HarjokoProblem statement: The Case Based Reasoning (CBR) method can be implemented in differential diagnosis analysis. C4.5 algorithm has been commonly used to help the method's knowledge building process. This process is completed by constructing decision tree from previously handled cases data. The C4.5 algorithm itself can be used with an assumption that all the cases has an exact and equal … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 8,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand Cover Change Detection Using Texture AnalysisXiaofeng Wu, Fen Yang, Roly LishmanProblem statement: It is an important task to detect land cover changes from remotely sensed data for environmental monitoring. Although there are some applications of visual textures to the land use, they are limited to a few land cover categories with the application of one texture measure. Since land cover types are complex and often the integration of various objects, … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 8,198 accessesView PDFCite
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 · 7,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractIndoor Navigation and Localization for Visually impaired people Using Weighted Topological MapMd Jan Nordin, Abbas M. AliProblem Statement: Image base methods are a new approach for solving problems of navigations for visually impaired people. Approach: The study introduced a new approach of an electronic cane for blind people using the environment represented as a weighted topological graph instead, each node contains images taken at some poses in the work space, instead of building a metric (3D) … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Weighted Rank CorrelationTahani A. Maturi, Ezz H. AbdelfattahProblem Statement: There have been many cases in real life where two independent sources have ranked n objects, with the interest focused on agreement in the top rankings. Spearman's rho and Kendall's tau coefficients assigned equal weights to all rankings. As a result, the literature proposed several weighted correlation coefficients with emphasis on the top rankings, including the top-down, weighted … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 8,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust and Blind Watermarking of Relational Database SystemsA. Al-Haj, A. OdehProblem statement: Digital multimedia watermarking technology was suggested in the last decade to embed copyright information in digital objects such images, audio and video. However, the increasing use of relational database systems in many real-life applications created an ever increasing need for watermarking database systems. As a result, watermarking relational database systems is now merging as a research area that … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Persistence Framework-Based Rapid Application Development Toolkit for Web Application DevelopmentChoon H. Choo, Sai P. LeeSoftware systems must be delivered quickly in order to respond to today's rapid changing business environments. Persistence framework was introduced to overcome the problem of object-relational impedance mismatch, occurred in most enterprise applications that need access to a relational database. However, most of these persistence frameworks are difficult to configure and use, thus do not really contribute much to the … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 6,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental and Theoretical Analysis of a Novel Flexible Membrane Tactile SensorGoldis Darb Emamieh, Ahmad Ameri, Siamak Najarian, Ali Tavakoli GolpayganiIn this study, we report the development of a new multi tactile sensor, capable of detecting 2D surface texture image, measuring contact-force, and identifying the difference between stiffness of sensed objects. The designed tactile sensor consists of a chamber and a membrane with a mesa structure. The detecting principle is a combination of membrane deflection and piezoresistance effects.
