Research ArticleOpen accessIn the abstractA Novel Method to Improve Weld Uniformity by Automatic Control of Current IntensityAbdul Aziz A. Morgan, Fahad A. Al-MufadiThis study aims to develop an automatic arc welding system capable of welding irregular and moving joints which are difficult to weld manually. The motivation of this research comes from the need to produce uniforms weldings on regular and irregular surfaces by automatic means. The system consists of a personal computer equipped with A/D interface card connected to an electric … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 26 Jan 2015 · 7,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractSPLINE ACTIVATED NEURAL NETWORK FOR CLASSIFYING CARDIAC ARRHYTHMIAY. S. Kumaraswamy, R. Ganesh KumarElectro Cardiogram’s (ECG) biomedical signals characterizing cardiac anomalies are used for identifying cardiac arrhythmia. Irregular heartbeat-Arrhythmia-affects heart rate causing problems. Many methods, trying to simplify arrhythmia monitoring through automated detection, were developed over the years. ECG classification for arrhythmia is investigated in this paper based on soft computing techniques. RR interval are extracted from time series of the ECG and … …Journal of Computer Science, Vol. 10, Issue 8 · 9 Apr 2014 · 6,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractEye Detection Using Composite Cross-CorrelationKutiba Nanaa, Mohamed Rizon, Mohd Nordin Abd Rahman et al.This study presents a new eye detection method depending on composite template matching for facial images. The objective of this study is to utilize template match method to detect the eyes from given images and to improve this method to obtain higher rate of detection. The idea of our method is to integrate cross correlations of various eye templates. Thus, … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 3 Oct 2013 · 6,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Mode of Action of Antibacterial Components from Melastoma malabathricum Linn LeavesMourouge Saadi Alwash, Nazlina Ibrahim, Wan Yaacob AhmadThe present study aimed to assess the antibacterial activity of the methanol extract of Melastoma Malabathricum Leaves (MMML), active fraction of M. Malabathricum Leaves (ML5) and isolated kaempferol-3-O-(2",6"-di-O-p-trans-coumaroyl)-β-glucopyranoside (Kf) and to describe the preliminary mode of action against Gram-positive and Gram-negative bacteria. The MMML extract was fractionated by Vacuum Liquid Chromatography (VLC) to afford M. malabathricum Leaves fractions (ML1-ML6) of … …American Journal of Infectious Diseases, Vol. 9, Issue 2 · 18 Jun 2013 · 12,621 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Wall Roughness and Concentration of Clay on Erosion in the Hole Erosion TestKissi Benaissa, Parron Vera Miguel Angel, Rubio Cintas Maria Dolores et al.Problem statement: Internal soil erosion is a real threat for hydraulic infrastructures. In its final stage it develops in piping involving the formation and progression of a continuous void inside the soil between the upstream and downstream sides. The hole erosion test was introduced to characterize kinematics of piping in terms of the time left to rupture. Actual modeling approaches … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 22 Nov 2010 · 8,506 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnchor Plates in Two-Layered Cohesion Less SoilsHamed Niroumand, Khairul Anuar Kassim, Ramli NazirProblem statement: During the past few years a great number of experimental model and numerical analysis results on the uplift resistance of anchor plate embedded in homogeneous cohesion less soil has been reported by many researchers. A review of related literature shows that not much research has been done to analyze the performance of anchor plates in layered soils a … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation and Evaluation of Evolutionary Connectionist Approaches to Automated Text SummarizationUday Kulkarni, Rajesh Shardanand PrasadProblem statement: Text summarization takes care of choosing the most significant portions of text and generates coherent summaries that express the main intent of the given document. This study aims to compare the performances of the three text summarization systems developed by the authors with some of the existing Summarization systems available. These three approaches to text summarization are based … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 8,489 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection and Localization of Anti and Pro-apoptotic mRNA Genes in Human Colorectal Cancer Using in situ RT-PCRMohd. Nazil Salleh, Boo Siaw Shi, Wan Khairuzzaman Wan Ramli et al.Problem statement: Recent studies using conventional Polymerase Chain Reaction have shown that anti-apoptotic (Cyclooxygenase-2, COX-2 and Nuclear Factor-κB, NF-κB) and proapoptotic mRNA (Bax and Bad) are involved in the tumorigenesis of colorectal cancer. The aim of this study was to localize the expression of anti and pro-apoptotic mRNA genes using Reverse Transcription in situ Polymerase Chain Reaction (RT in situ … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,441 accessesView PDFCite
