Research ArticleOpen accessEvery word in the titleMeasurements of Mitral Annular Displacement in 2D Echocardiography ImagesFaten A. Dawood, Rahmita W. Rahmat, Suhaini B. Kadiman et al.Mitral Annular Displacement (MAD) in echocardiography has been described as a variation in mitral annulus position between the end-diastolic and the end-systolic in a complete cardiac cycle. It could be used as a rapid and reproducible method of determining the LV global systolic function and could be an easily detectable index for wall motion abnormalities. In this study, a computational … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 4 Jul 2015 · 6,850 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsTunnel Static Behavior Assessed by a Probabilistic Approach to the Back-AnalysisClaudio Oggeri, Pierpaolo OresteProblem statement: The steps of the validation procedure of the project of a tunnel are briefly illustrated in this study, starting from the geological and structural surveys on the excavation walls and the measurement of the physical and mechanical parameters during the excavation works. Unfortunately, however, the knowledge of the rock mass, which is fundamental to the project, is usually … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 7,030 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Construction of a Smart Meter with Embedded Web PortalDavid Mike-Ewewie, Ayodele Ifijeh, Victoria Oguntosin et al.The absence of the necessary infrastructure to make an accurate and precise collection of data when compared to the first-world countries in the power industry is great. Due to that, the need for the deployment of smart meters has increased in order to offer consumers and customers awareness of their electricity usage, helping them lower their total energy footprint. In … …Journal of Computer Science, Vol. 20, Issue 8 · 14 Jun 2024 · 5,275 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDownstream Ecocide from Upstream Water PiracyMiah Muhammad AdelUpstream India and downstream Bangladesh share more than 50 international rivers. India has set up water diversion constructions in more than 50% of these rivers, the largest one being on the Bangladesh’s northwest upon the Ganges River, puts Bangladesh’s Gangetic ecosystem at stake. In some border rivers, India has set up groins on her side of river banks. Also, Indian … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 4 Sep 2012 · 9,067 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInclusion Identification by Inverse Application of Boundary Element Method, Genetic Algorithm and Conjugate Gradient MethodMahmud Khodadad, Mohsen Dashti ArdakaniCharacterization of the interior of an inhomogeneous body using displacement measurements obtained by conducting a simple tension test was investigated. A homogeneous elastic solid body is assumed to have another solid body with arbitrary shape hidden inside it. The shape and physical properties of this inclusion were unknown. The Boundary Element Method (BEM) coupled with a mete heuristic Genetic Algorithm … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,758 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Convergence-Confinement Method: Roles and Limits in Modern Geomechanical Tunnel DesignPierpaolo OresteThe convergence-confinement method, based on the analysis of the stress and strain state that develops in the rock around a circular tunnel, has been presented in this study with the two analytical solutions that have been most frequently used in recent years. Problem statement: Thanks to the increased power of electronic processors and the spread of numerical methods, the role … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 10,151 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPressure-sensitivity Effects on Toughness Measurements of Compact Tension Specimens for Strain-hardening SolidsAbdulhamid A. Al-AbduljabbarThe path-independent J-integral is used as a fracture prediction criterion for loading beyond the elastic limit as Linear Elastic Fracture Mechanics (LEFM) cannot be applied. While J was originally defined from an energy perspective, it was demonstrated that it could be inferred from load-displacement diagrams. Therefore, the Compact Tension (CT) specimen testing is used to compute J for materials. In … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,657 accessesView PDF Cite
