Research ArticleOpen accessIn the abstractIdentification of Flutter Derivatives of Bridge Decks in Wind Tunnel Test by Stochastic Subspace IdentificationT. Janesupasaeree, V. BoonyapinyoProblem statement: Flutter derivatives are the essential parameters in the estimations of the flutter critical wind velocity and the responses of long-span cable supported bridges. These derivatives can be experimentally estimated from wind tunnel test results. Generally, wind tunnel test methods can be divided into free decay test and buffeting test. Compared with the free decay method, the buffeting test … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Lateral Reaction of a Deformable Inclined Surface on a Wheel with an Elastic TrunkSayel M. Fayyad, Suleiman Abu-Ein, Waleed MomaniProblem statement: This study is concerned with a very important problem belonging in the effects of deformable inclined surfaces on a wheel with an elastic trunk. These effects can be represented by two effects: A lateral withdrawal of the trunk and lateral shift of the ground. Also this study aims to study these effects and analyze them mathematically to find … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractDisposition of Human Resource Development Structure in Manufacturing Firms in MalaysiaAbdullah HaslindaProblem statement: Human Resource Development (HRD) is rapidly gaining importance in manufacturing firms in Malaysia, as there are strong driving forces such as legal, financial and infrastructural support from the Government. This is because the Government believes that investment in human capital is key to the success of the country’s economy. However, this strategy may not be effective without the … …Journal of Social Sciences, Vol. 5, Issue 1 · 31 Mar 2009 · 7,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Hyperplanes of the Geometry D4,2 and their Related CodesAbdelsalam Abou ZaydaProblem statement: The point-line geometry of type D4,2 was introduced and characterized by many authors such as Shult and Buekenhout and in several researches many of geometries were considered to construct good families of codes and this forced us to present very important substructures in such geometry that are hyperplanes. Approach: We used the isomorphic classical polar space Ω+(8, F) … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,103 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing a Truss-Inspired Model with the Uniform Strength Optimization Theory to Predict Spongy Bone Geometry in Proximal FemurHamed Pishdast, Farzam Farahmand, Gholamreza RouhiThis paper presents a new naïve approach for simulating bone remodeling process. It is based on the uniform strength theory of optimization and employs a truss-like model for bone. The truss was subjected to external loads including 5 point loads simulating the hip joint contact forces and 3 muscular forces at the attachment sites of the muscles to the bone … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,174 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Presence of Growth and Remodeling in the Bone Adaptation TheorySeyyed Amir Hooshiar Ahmedi, Gholamreza Rouhi, Hamidreza Katouzian, Seyyed Ali Hooshiar AhmediMechanical forces acting on bone during growth affect their final shape and strength. Mechanoregulation of bone growth is maybe recognized in embryogenesis, and also in the adaptation of the adult skeleton to changes in mechanical loading. By combining equations describing bone remodeling and growth with an iterative finite element analysis, a computational model to simulate the simultaneous effects of bone … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,166 accessesView PDFCite

Research ArticleOpen accessIn the abstractAlmost Graded Prime IdealsAmeer Jaber, Malik Bataineh, Hani KhashanProblem Statement: Graded commutative ring with unity over an abelian group were introduced by many authors such as T. Y. Lam and C. T. C. Wall, and almost prime ideals over commutative rings with unity were introduced by S.M. Batwadeker and P.K. Sharma, and this forced us to try to extend the theory of almost and n-almost prime ideals to … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerobic Biostabilization of Old MSW LandfillsM.C. ZanettiMany years after the end of the cultivation phase, landfills may generate intense odours, toxic and explosive gases and heavily-polluted leachate. A wide-spreading trend in the management of MSW landfills is represented by the forced aeration of wastes in order to achieve the stabilization, reducing the negative environmental impact of uncontrolled sites (old landfills which can be definitely considered as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,233 accessesView PDFCite
