Research ArticleOpen accessIn the abstractStress-Strain Analysis of Abdominal Aortic Wall: A Case of 3D Geometry SimulationP. Khamdaengyodtai, P. Sakulchangsatjatai, P. TerdtoonProblem statement: This study analyzed stress-strain of abdominal aortic wall in 3D geometry simulation. Abdominal aorta is a portion of the aorta vessel in the abdomen which many cardiovascular diseases often occur. Approach: Abdominal aortic wall was considered as 1 layers-3 dimensional cylindrical geometry and homogeneous, incompressible and anisotropic material. Deformation of aortic wall was elastic deformation. Numerical method was … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractCreep predicting model in masonry structure utilizing dynamic neural networkMustafa M. Abed, A. El-Shafie, Siti Aminah Bt. OsmanProblem statement: When the loads are applied to a brickwork structure, visco-elastic behavior upon their stress-strain relationships is exhibited, where the response can be classified into two separate parts: an instantaneous elastic strains and time-dependent creep strains. The creep strain represents the non- instantaneous strain that happens with time when the stress is sustained. Through the previous century, along with … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 7,627 accessesView PDFCite
Research ArticleOpen accessIn the abstractConfined High Strength Concrete Columns: An Experimental StudyJagannathan Saravanan, K. Suguna, P. N. RaghunathProblem statement: An experimental study on GFRP confined high strength concrete columns has been carried out with a view to evaluate its performances under uni-axial compression in terms of load and deformation capacity. Approach: High strength concrete columns strengthened with different configuration and stiffness of GFRP wraps were tested under axial compression until failure. Their response evaluated at different load … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,642 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 abstractEffect of Joint Flexibility on Overall Behavior of Jacket Type Offshore PlatformsMasoud Mirtaheri, Hossein Ali Zakeri, Pejman Alanjari, Mohammad Amin AssarehProblem Statement: Nonlinear behavior of offshore structure is attracting tremendous amount of attention in recent years. Response of these structures is strictly dependent upon behavior of their joints. Because of the lack of information about this part of a structure, most of the recent analysis and designs do not contain appropriate material in the case of joints. In most cases, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Blood Turbulent Flow in Carotid Artery Including the Effects of Mural Thrombosis Using Finite Element ModelingM. Arab-Ghanbari, M. M. Khani, A. Arefmanesh, F. Tabatabai-GhomsheArterial thrombosis is an extremely significant health problem. As a result of numerous factors involved in such problem, describing the role of hemodynamics in thrombogenesis has been asserted to be one of the most demanding and complicated challenges in biomechanics. An axisymmetric model considering fluid-structure interactions (FSI) was introduced and numerically solved for an artery with a thrombosis to perform … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,408 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality Evaluation of Reconstructed Biological SignalsMikhled Alfaouri, Khaled Daqrouq, Ibrahim N. Abu-Isbeih et al.This research presents the use of wavelet transforms for reconstructed signal evaluation for biological signals. The method adapted on this research, is a new modeling technique and based on calculating the reconstruction error of the wavelet transform sub-signals that have different frequency bands and different deformation degree. The paper processes a special set of application in biomedical field, called Electrocardiogram … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 9,107 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Behavior of A High Anchored Reinforced Earth WallFaisal Hj Ali, Bujang B.K. Huat, Lee Chee HaiSince the invention of Reinforced Earth by the French architect Hendri Vidal in 1966, numerous reinforced soil walls have been designed and constructed all over the world. In this study the focus was on a particular type of reinforced wall called Nehemiah wall which differed from the Vidal type in the sense that instead of steel strips, the reinforcing elements … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evaluation of Anti-Stripping Additives Mixing in Road Surface Pavement MaterialsTienfuan Kerh, Yu-Min Wang, Yulern LinMost road surfaces in Taiwan are paved with asphalt concrete but the phenomena of rutting, cracking and stripping of the pavement are frequently occurring due to the effects of traffic flow, thermal variation and water erosion caused by rain. In this study, a series of experiments were performed to examine the effectiveness of anti-stripping fillers, which include; rock flour, rock … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractq-Euler Lagrange EquationAmna Hasan, Hakeem A. Othman, Sami H. AltoumIn this work, for q ∈ (0, 1), the q-deformation of Euler- Lagrange equation is studied; we use q-derivative (or Jackson derivative) to deduce a new formula of Euler- Lagrange equation. Some examples are presented. …American Journal of Applied Sciences, Vol. 16, Issue 9 · 22 Nov 2019 · 7,757 accessesView PDFCite
