Research ArticleOpen accessIn the abstractHiding a Large Amount of Data with High Security Using Steganography AlgorithmNameer N. EL-EmamThis study deals with constructing and implementing new algorithm based on hiding a large amount of data (image, audio, text) file into color BMP image. We have been used adaptive image filtering and adaptive image segmentation with bits replacement on the appropriate pixels. These pixels are selected randomly rather than sequentially by using new concept defined by main cases with … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 8,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractOne Algebra of New Generalized FunctionsSabra RamadanThe space of new Generalized functions ζ (Π(R)) has been constructed. The operation of associative multiplication Θ has been defined on ζ (Π(R)).The embedding Jπ : ζ(S(R))→ ζ( (R)) has been constructed. …Journal of Mathematics and Statistics, Vol. 3, Issue 1 · 31 Mar 2007 · 7,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeterministic Timed AFA: A New Class of Timed Alternating Finite AutomataAbdelaziz Fellah, Zachary Friggstad, Soufiane NoureddineTimed Alternating Finite Automata (TAFA), a natural generalization of Timed Finite Automata (TFA), are synchronous and powerful models for real-time computations. They become an effective and expressive model for developing embedded systems with real-time constraint computations which are required in many applications. We introduce Deterministic Timed Alternating Finite Automata (DTAFA), a new class of timed alternating finite automata, extended with … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,499 accessesView PDFCite
Research ArticleOpen accessIn the abstractWound Healing Process of Uncomplicated “Rusterholz” Ulcer, Following Treatment by Wooden Block and Hoofgel® in Bovine Hoof: Histopathological AspectsH. Azarabad, I. Nowrouzian, E. Soleymani et al.A broad and very detailed histopathological knowledge on cutaneous wound healing particularly in human skin is available, but few studies have documented this event in bovine claw sole ulcers. It seems the mechanism of wound healing might be basically the same followed by second intention healing which is finished in a period of time by formation of granulation tissue in … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 31 Dec 2006 · 7,847 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeedup of Particle Transport Problems with a Beowulf ClusterZhongxiang Zhao, G. Ivan MaldonadoThe MCNP code is a general Monte Carlo N-Particle Transport program that is widely used in health physics, medical physics and nuclear engineering for problems involving neutron, photon and electron transport[1]. However, due to the stochastic nature of the algorithms employed to solve the Boltzmann transport equation, MCNP generally exhibits a slow rate of convergence. In fact, engineers and scientists … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Dec 2006 · 6,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cooperative Intelligent Decision Support System for Contingency ManagementAbdelkader ADLATraditional Decision Support Systems (DSS) give not enough possibilities of intervention to the user. These systems are reduced to an insular and very technical state in which the objective is not support decision but to dump data on the screen in the hope that the user will know what to do with. In complex situations, decision is not structured and … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractNanocrystalline Powders of Alkaline-Earth Phosphates as Precursors for BioceramicsParhi Purnendu, A. Ramanan, Alok R. RayBone is a nanocomposite made of calcium phosphates and collagen. Collagen has a typical fibrous structure, with diameter ranging from 100 nm to 2 μm. It is suggested that calcium hydroxyapatite, Ca10(PO4)6(OH)2 in the size range 5-50 nm embedded in the collagen framework provides mechanical strength to bone. Among calcium phosphates, apatites are found to be the most suitable for … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,543 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Filtering Algorithm for Duplicate Document Based on Concept AnalysisAhmad M. HasnahData bases and web pages contain currently a huge number of duplicate document. It is then fundamental to have a filter which can be embedded, for instance, within an information retrieval system like a search engine in order to prohibit the redundant documents references to appear on the screen as a reply to the user's query. This filter can save … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Study Using FE Code (PLAXIS) on the Geotechnical Behavior of Shell FootingsBujang B.K. Huat, Thamer A. MohammedThis study describes a study on the geotechnical behavior of shell footing using a non-linear finite element analysis with a finite element code, PLAXIS. The shell footing is found to have a better load carrying capacity compared with the conventional slab/flat footing of similar cross sectional area. The FE analysis also showed a reasonably good agreement with the laboratory experimental … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,884 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Scheme for Digital Watermarking Using Functional Link Artificial Neural NetworkBanshidhar Majhi, Hasan ShalabiThe present study proposes a novel technique for copyright protection by utilizing digital watermarking of Images. The watermark is embedded and detected by using Functional Link Artificial Neural Network (FLANN) and Discrete Cosine Transform (DCT). The exhaustive simulation results of the proposed scheme show improved performance over the existing methods in all cases, i.e. when the watermarked image is subjected … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,861 accessesView PDFCite
