Research ArticleOpen accessIn the abstractIntegrity Classification Algorithm of Images obtained from Impact Damaged Composite StructuresMahmoud Z. IskandaraniProblem statement: Many NDT systems used for damage detection in composites are difficult to apply to complex geometric structures, also, they are time-consuming. As a solution to the problems associated with NDT applications, an intelligent analysis system that supports a portable testing environment, which allowed various types of inputs and provided sufficient data regarding level of damage in a tested … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,972 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputational Complexity between K-Means and K-Medoids Clustering Algorithms for Normal and Uniform Distributions of Data PointsT. Velmurugan, T. SanthanamProblem statement: Clustering is one of the most important research areas in the field of data mining. Clustering means creating groups of objects based on their features in such a way that the objects belonging to the same groups are similar and those belonging to different groups are dissimilar. Clustering is an unsupervised learning technique. The main advantage of clustering … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 19,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractModified Center Interpolation Net for Classification of Composite Structures Tested Using Low Frequency Electronic TappingMahmoud Z. IskandaraniProblem statement: Most exhaustive NDT techniques require large capital equipment, are difficult to apply to complex geometric structures and, above all, are time-consuming to use and some take a considerable time to complete. As a solution to the problems associated with NDT applications, there is a need to establish an intelligent analysis system that supports a portable testing environment, which … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,110 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Flow Structures of Circular Pulsating Air JetRozli Zulkifli, Kamaruzzaman Sopian, Shahrir Abdullah, Mohd Sobri TakriffProblem Statement: Applications of impingement jets in industry for heating and cooling purposes requires a high convective heat transfer coefficient. Numerous studies have been conducted to improve the convective heat transfer coefficient for a steady impinging jet. A pulsating jet has a very high potential in replacing steady jet after it been found able to increase the heat transfer coefficients … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Processing for Binary Submatrix MatchingAzzam Sleit, Wesam AlMobaideen, Mohammad Qatawneh, Heba SaadehThe heavy demand for large volumes of digital data has increased the interest in matrix-like representation. Matrices are well organized data structures which are suitable to store uniform data in order to simplify data access and manipulation. For several applications, the need is critical to efficiently search for a specific pattern in matrix structures. A pattern can be represented as … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,622 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving 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 · 7,537 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of HCV Components and Pathological Reactions in Apoptotic Hepatocytes from Chronically HCV-infected PatientsViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Analysis of Hepatitis C Virus (HCV)-infected hepatocytes at the cellular level may contribute to elucidate the mechanisms of HCV pathogenesis. In this work, the presence of HCV components and pathological reactions in apoptotic hepatocytes from chronic HCV-infected patients were studied by electron microscopy and confocal microscopy. Eight samples of liver biopsies from patients with chronic hepatitis C were studied by … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractMinimum Free Energy Based Evaluation of mRNAs Secondary Structures Constructed by 18 Clinically Significant Exonic Single Nucleotide Polymorphisms (SNPs) and Haplotypes of 5 Missense SNPs of RB1 GeneSarder Nasir Uddin, Apurba Majumder, Khandker Khaldun Islam et al.Clinically significant 18 Single Nucleotide Polymorphisms (SNPs) from exon regions of Retinoblastoma gene (RB1) were analyzed to find out the structural variations in mRNAs. Online bioinformatic tools i.e., Vienna RNA, RNAfold were used for secondary structure analysis of mRNAs. Predicted minimum Free Energy Change (MFE) was calculated for mRNAs structures. It has been observed that the average of predicted MFE … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 21 Oct 2015 · 8,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractModified ACS Centroid Memory for Data ClusteringAyad Mohammed Jabbar, Ku Ruhana Ku-Mahamud, Rafid SagbanAnt Colony Optimization (ACO) is a generic algorithm, which has been widely used in different application domains due to its simplicity and adaptiveness to different optimization problems. The key component that governs the search process in this algorithm is the management of its memory model. In contrast to other algorithms, ACO explicitly utilizes an adaptive memory, which is important to … …Journal of Computer Science, Vol. 15, Issue 10 · 11 Oct 2019 · 7,647 accessesView PDFCite
