Research ArticleOpen accessIn the abstractBayesian Exploration of Multilocus Interactions on the Genome-Wide ScaleIvan Kozyryev, Jing ZhangProblem statement: Recent technological and scientific advances propelled the field of Genome-Wide Association Study (GWAS), which promises to be instrumental in linking many common complex diseases to their genetic origin. While so far such large-scale surveys have been moderately successful in identifying disease related genetic variants, much of disease heritability is still not accounted for by the discovered loci. There … …Current Research in Bioinformatics, Vol. 1, Issue 1 · 2 Jul 2012 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractFramework for Managing the Very Large Scale Integration Design ProcessSabah Al-Fedaghi, Eman Al-DwaisanProblem statement: The VLSI design cycle was described in terms of successive states and substages; it starts with system specification and ends with packaging. At the next descriptive level, currently known methodologies (e.g., flowchart based, object-oriented based) lack a global conceptual representation suitable for managing the VLSI design process. Technical details were intermixed with tool-dependent and implementation issues such as … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 13 Dec 2011 · 7,491 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Face Recognition Technique Based on Modular LPCA ApproachMathu Soothana S. Kumar, Retna Swami, Muneeswaran KaruppiahProblem statement: A face identification algorithm based on modular localized variation by Eigen Subspace technique, also called modular localized principal component analysis, is presented in this study. Approach: The face imagery was partitioned into smaller sub-divisions from a predefined neighborhood and they were ultimately fused to acquire many sets of features. Since a few of the normal facial features of … …Journal of Computer Science, Vol. 7, Issue 12 · 22 Oct 2011 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractSegmentation of Medical Image using Clustering and Watershed AlgorithmsM.C. Jobin Christ, R.M.S. ParvathiProblem statement: Segmentation plays an important role in medical imaging. Segmentation of an image is the division or separation of the image into dissimilar regions of similar attribute. In this study we proposed a methodology that integrates clustering algorithm and marker controlled watershed segmentation algorithm for medical image segmentation. The use of the conservative watershed algorithm for medical image analysis … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 22 Oct 2011 · 8,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Hyper Clustering Algorithms in Mobile Network PlanningLamiaa Fattouh Ibrahim, Hesham A. SalmanProblem statement: As a large amount of data stored in spatial databases, people may like to find groups of data which share similar features. Thus cluster analysis becomes an important area of research in data mining. Applications of clustering analysis have been utilized in many fields, such as when we search to construct a cluster served by base station in … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 30 Aug 2011 · 7,504 accessesView PDFCite

Noraziah, Noriyani Mohd Zain et al.Problem statement: Organizations critically needed to supply recent data to users who may be geographically remote, while at the same time handle a volume request of distributed data around multiple sites. The storage, availability and consistency are important issues to be addressed in order to allow distributed users efficiently and safely access data from many different sites. Approach: Data replication … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcknowledgment based Reputation Mechanism to Mitigate the Node Misbehavior in Mobile Ad Hoc NetworksK. Gopalakrishnan, V. Rhymend UthariarajProblem statement: The cooperation between the nodes is essential to discover and maintain routes in mobile ad hoc network. Due to the presence of misbehaving nodes, the node cooperation is not always guaranteed as the nodes agreed during the route discovery phase. This phenomenon results in frequent network partitioning and it makes the routing process difficult. It also degrades the … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,567 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Markov Chains to Stock TrendsKevin J. Doubleday, Julius N. EsungeProblem statement: Modeling of the Dow Jones Industrial Average is frequently attempted in order to determine trading strategies with maximum payoff. Changes in the DJIA are important since movements may affect both individuals and corporations profoundly.
