Research ArticleOpen accessIn the abstractA Biomechanical Composite Model to Determine Effective Elastic Moduli of the CNS Gray MatterMehdi Khoshgoftar, Siamak Najarian, Farhad Farmanzad et al.Brain tissue is a heterogeneous material with complicated microstructural features. Models based on microstructure can lead to more accurate and physically realistic predictions of mechanical characteristics of brain tissue. A two-step Mori-Tanaka/Voigt homogenization procedure is implemented into a 3D microstructurally-based multi-phase composite model, composed of randomly-oriented elastic axons, dendrites and neuronal cell bodies surrounded by an elastic matrix. The effects … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Digital Signature Scheme Based on Mandelbrot and Julia Fractal SetsMohammad Ahmad Alia, Azman Bin SamsudinThis paper describes a new cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Having fractal based digital signature scheme is possible due to the strong connection between the Mandelbrot and Julia fractal sets. The link between the two fractal sets used for the conversion of the private key to the public key. Mandelbrot fractal function takes the … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 6,964 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Error Correction Intuitive Approach in Quantum Communications ProtocolsAris Skander, Merabtine Nadjim, Malek BenslamaQuantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory of quantum error correction based on encoding states into larger Hilbert spaces subject to known interactions. We obtain necessary and sufficient conditions for the perfect recovery of an encoded state after its degradation by … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,842 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling for Shakedown Analysis of Offshore StructuresMohammad Javad Fadaee, Hamed Saffari, Ramin TabatabaeiThe shakedown analysis process of an offshore structure having elastic-plastic material presented. The finite element model of the structure has been developed first, and then a simple method has been applied for shakedown analysis using matrix tool. Simplifying the relationships together with applying the theory concepts of shakedown analysis is one of the characteristics of the presented method for practical … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Main Object-oriented Projective Invariant Image Watermarking ApproachMalik F. AlamairehDigital Watermarking is a technology that enables to protect distributed digital content from unauthorized reuse. Robust watermarks must be able to survive a range of geometrical "attacks," such as image resizing, cropping, translation, rotation, scaling, smoothing, filtering, and simplification. In the current paper we extend existing approaches that are based partially on image invariant features; by introducing new image invariant … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractTwo Main Methods for Utility Sharing in Joint Business: A DiscussionRafel Amer, Francesc Carreras, Antonio MagañaOne of the main purposes of any theory of joint business is to provide a convincing way for sharing the total utility available to the set of agents. The proportional rule is widely applied in practice but people using this method should be warned that it is not as innocent, effective, fair and consistent as it seems at first glance. … …Journal of Mathematics and Statistics, Vol. 3, Issue 1 · 31 Mar 2007 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Vibration Analysis of a Cross-Ply Laminated Composite Beam on Pasternak FoundationR. A. Jafari-Talookolaei, M. T. AhmadianIn this study, free vibration analysis of a cross-ply laminated composite beam (LCB) on Pasternak foundation was investigated. Natural frequencies of beam on Pasternak foundation are computed using finite element method (FEM) on the basis of Timoshenko beam theory. Effect of both shear deformation and rotary inertia are implemented in the modeling of stiffness and mass matrices. The model was … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Face Concern Approach to Conflict Management - A Malaysian PerspectiveRaduan c. Rose, Waitchalla R. Suppiah, Jegak Uli, Jamilah OthmanThis study presents a review of conflict management from a face concern approach. It presents the various definitions on conflict and types of conflict. It further looks at how face negotiation theory explains the use of various conflict management styles in individualist and collectivist cultures. In addition, it provides some insight into conflict management from a Malaysian perspective. …Journal of Social Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 8,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractWell-Posedness of Second Order Uniformly Elliptic Boundary Control Systems with Additive or Multiplicative UncertaintyAda ChengBoundary control systems arises naturally in many applications. Any modelling of real systems involve uncertainty. Sufficient conditions for well-posededness for additive or multiplicative uncertainty are presented through the use of matrix theory. …Journal of Mathematics and Statistics, Vol. 2, Issue 4 · 31 Dec 2006 · 6,140 accessesView PDFCite
