Research ArticleOpen accessEvery word in the titleImpedance Method Application for Multi-Layer Structure TestingMonzer Moh’D KrishanMulti-layer materials and structures are widely used in the modern aircraft industry. The main defect of these structures is delamination. The most appropriate method for detection of such kind flaws is the impedance testing method. This research is devoted to the features of the impedance method for multi-layer panel testing. The theoretical and experimental investigations of mechanical impedance are presented … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,282 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproving Protein 3D Structure Prediction Accuracy using Dense Regions Areas of Secondary Structures in the Contact MapAmer F. Al-Badarneh, Mohammad A. Khalil, Mo'taz A. Al-HamiProblem Statement: The protein folding problem is a fundamental problem in structural molecular biology. This problem describes how a protein is transformed from its primary sequence (i.e., amino acid sequence) into the three dimensional structure (3D structure) for this sequence that determines the function of the protein. The 3D structure of a protein can be represented using a square symmetrical … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,533 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleParsing Arabic Texts Using Rhetorical Structure TheoryH. I. Mathkour, A. A. Touir, W. A. Al-SaneaProblem Statement: Processing texts based on rhetorical structure theory has shown interesting results. Rhetorical Structure Theory (RST) improves the ability of extracting the semantic behind the processed text. Different applications such as information retrieval, text summarization, and text generation have proved to give better result using RST. The applicability of RST to process and understand texts has been studied in … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,389 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSoil Structure Interaction between Two Adjacent Buildings under Earthquake LoadMahmoud Yahyai, Masoud Mirtaheri, Mehrab Mahoutian et al.In some cases, tall buildings are located in geotechnically unsuitable places, due to their high ratio of height to width; there is risk of uplift and other effects such as overturning and reduction structure serviceability during earthquake. This research is aimed to evaluate the effect of Soil-Structure Interaction (SSI) on seismic behavior of two adjacent 32 story buildings such as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 9,345 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Artificial Neural Network Based Approach for Mortality Structure AnalysisSokolova M. Kursk, Rashad J. Rasras, D. SkopinThe theoretical outcomes and experimental results of applying of Artificial Neural Networks towards mortality structure examination in Russian Federation are presented in the paper. The most influencing classes of diseases are selected by sensitivity analysis. It is proved that Neural Network Models appear to be an adequate tool for mortality structure examination. Some interesting results for males and females total … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Sep 2006 · 7,056 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhotoelectrochemical Corrosion of GaN/AlGaN-Based p-n StructuresAlexander Usikov, Heikki Helava, Alexey Nikiforov et al.Direct water photoelectrolysis using III-N materials is a promising way for hydrogen production. GaN/AlGaN based p-n structures were used as working electrodes in a photoelectrochemical process to investigate the material etching (corrosion). The structures were grown on sapphire substrates by chloride Hydride Vapor Phase Epitaxy (HVPE). First, the etching process occurs near vertically via channels associated with defects in the … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 31 Jul 2016 · 7,335 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStructure Prediction and Binding Site Analysis of Hepatotoxic Microcystin-LR Degrading MlrC-Like Protein from Burkholderia sp. using Computational ApproachesDhananjaya P. Singh, Ratna Prabha, Vivek Keshri, P.C. AbhilashMicrocystin-LR (MCYST-LR) is a well characterized hepatotoxic heptapeptide produced by various species of cyanobacteria including Microcystis aeruginosa. Burkholderia is a genus of bacteria with cyanobacterial toxins degrading property. This study predicts the structure of microcystin degrading MlrC-like protein from Burkholderia sp. strain CCGE1002 that has microcystin degradation capability. Binding interaction of MlrC-like protein with MCYST-LR was studied. Three-dimensional model of … …Current Research in Bioinformatics, Vol. 5, Issue 1 · 10 Jun 2016 · 8,069 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCommunity Structure and Abundance of Tintinnids in the Bay of Bengal During the SpringHuaxue Liu, Liangmin Huang, Zhixin Ke et al.The Bay of Bengal (BoB) locates in eastern part of the northern Indian Ocean, with a unique inter-related oceanographic system due to the monsoon and enormous runoffs’ supply. microbial food web often dominated the stratified Tropical Ocean, while few studies have been taken up to the tintinnids ciliates. Community structure and abundance of tintinnids were investigated in transact 10° N … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 20 Sep 2012 · 7,898 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Spot Diameter and Sheets Thickness on Fatigue Life of Spot Welded Structure based on FEA ApproachM. M. Rahman, A. B. Rosli, M. M. Noor et al.This study presents the effect of the spot weld and sheets thickness on the fatigue life of the of the spot-weld joints to predict the lifetime and location of the weakest spot-welds due to the variable amplitude loading conditions. A simple model was used to illustrate the technique of spot-weld fatigue analysis. Finite element model and analysis were carried out … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,864 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFlow Characteristics in Elastic Arteries Using a Fluid-Structure Interaction ModelH. Niroomand Oscuii, M. Tafazzoli Shadpour, Farzan GhalichiIn this study the interaction of blood flow with arterial wall has been investigated using FSI (Fluid-Structure Interaction) modeling. Computer simulation of pulsatile blood flow was carried out on the basis of the time dependent axisymmetric Navier-Stokes equations for an incompressible Newtonian fluid flow. An elastic incompressible material with large deformation was considered for the arterial wall and momentum and … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,429 accessesView PDFCite
