Research ArticleOpen accessIn the abstractFuzzy Meta Node Fuzzy Metagraph and its Cluster AnalysisD. Gaur, A. Shastri, R. BiswasProblem statement: In this study researchers propose a new fuzzy graph theoretic construct called fuzzy metagraph and a new method of clustering finding the similar fuzzy nodes in a fuzzy metagraph. Approach: We adopted T-norms (Triangular Norms) functions and join two or more T-norms to cluster the fuzzy nodes. Fuzzy metagraph is the fuzzyfication of the crisp Metagraphs using fuzzy … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,955 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Embeddings of Hamiltonian Paths and Cycles in Extended Fibonacci CubesIoana Zelina, Grigor Moldovan, Ioana TascuThe interconnection network is an essential component of a distributed system or of a supercomputer based on large-sale parallel processing. Because in distributed systems the communication between processors is based on message exchange, the network topology is of a great importance. The interconnection network can be seen as a graph and the properties of a network can be studied using … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractBoundary Shear Stress around Bridge PiersMirali MohammadiThis research presents the measurement of boundary shear stress around the base of some elliptical shaped bridge piers using Preston tube technique. The uniform flow was established and a series of measurements having different discharges and channel bed slopes were undertaken. General results are established and then the effects of flow separation on the hydraulic theory are assessed. The Analysis … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,711 accessesView PDFCite
Research ArticleOpen accessIn the abstractReed-Muller Codec Simulation PerformanceO. O. Khalifa, A. H. Abdullah, N. Suriyana et al.The approach to error correction coding taken by modern digital communication systems started in the late 1940's with the ground breaking work of Shannon, Hamming and Golay. Reed-Muller (RM) codes were an important step beyond the Hamming and Golay codes because they allowed more flexibility in the size of the code word and the number of correctable errors per code … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 7,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractMining Functional Dependency from Relational Databases Using Equivalent Classes and Minimal CoverJalal Atoum, Dojanah Bader, Arafat AwajanData Mining (DM) represents the process of extracting interesting and previously unknown knowledge from data. This study proposes a new algorithm called FD_Discover for discovering Functional Dependencies (FDs) from databases. This algorithm employs some concepts from relational databases design theory specifically the concepts of equivalences and the minimal cover. It has resulted in large improvement in performance in comparison with … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Design of ADAT: A Tool for Assessing Automata-Based AssignmentsZarina Shukur, Nurul Fatihah MohamedThis study describes the design of an automatic assessment system for assessing an automata-based assignment. Automata concept is taught in several undergraduate computing courses such as Theory of Computation, Automata and Formal Languages and Compilers. We take two elements into consideration when assessing the student's answers; static element and dynamic element. The static element involves the number of states (initial … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 7,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractFractal (Mandelbrot and Julia) Zero-Knowledge Proof of IdentityMohammad Ahmad Alia, Azman Bin SamsudinWe proposed a new zero-knowledge proof of identity protocol based on Mandelbrot and Julia Fractal sets. The Fractal based zero-knowledge protocol was possible because of the intrinsic connection between the Mandelbrot and Julia Fractal sets. In the proposed protocol, the private key was used as an input parameter for Mandelbrot Fractal function to generate the corresponding public key. Julia Fractal … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,965 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Relationship Between National Culture and E-Adoption: A Case Study of IranAkram Hadizadeh Moghadam, Parisa AssarNational Culture, in the sense of the shared traditions and representations of a society, has a profound effect on the design, adoption and the use of Information Technologies in each society. E-Adoption refers to the adoption of Information Technology and internet. Using Hofstede theory as the primary theoretical framework, through a review of existing studies, the current study attempted to … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractMaximum Principles for Second Order Elliptic Equations in Nondivergence Form and ApplicationsMohammad Al-MahameedThe main objectives of this study were to introduce a maximum principle for second order elliptic equations in nondivergence form and to use a nondivergence technique called the ABP method to establish the maximum principles in small domains. The advantage of this work was that we obtain a maximum principle for equations with discontinuous coefficients of the leading terms and … …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 6,859 accessesView PDFCite
