Research ArticleOpen accessIn the author namesFace Recognition using Eigenfaces and Neural NetworksMohamed Rizon, Muhammad Firdaus Hashim, Puteh Saad et al.In this study, we develop a computational model to identify the face of an unknown person’s by applying eigenfaces. The eigenfaces has been applied to extract the basic face of the human face images. The eigenfaces is then projecting onto human faces to identify unique features vectors. This significant features vector can be used to identify an unknown face by … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,940 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDevelopment of Pulsed Laser Deposition System for the Formation of Web-liked Carbon NanotubesNoorhana Yahya, Beh Hoe Guan, Mansor HashimThis work reports on our earnest effort to develop a pulsed laser ablation deposition system for the production of carbon nanotubes (CNTs). The correct condition such as the pressure, ablation time, power of laser will result in different structures and morphology of the tubes. A T-shaped stainless steel chamber was designed. Nd:YAG laser with 532 nm wavelength, 10.54W output power … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,036 accessesView PDF Cite

Research ArticleOpen accessIn the author namesModified Shear Box Test Apparatus for Measuring Shear Strength of Unsaturated Residual SoilBujang B.K. Huat, Faisal Hj Ali, S. HashimResidual soils occur in most countries of the world but the greater areas and depths are normally found in tropical humid areas. Most of these soils exhibit high suctions for most of the year. The shear strength parameters, c’ and Φ’, of soil can be obtained using conventional shear strength tests. However the conventional shear strength test equipments would not … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 7,046 accessesView PDF Cite

Research ArticleOpen accessIn the author namesTaxifolin Potently Diminishes Levels of Reactive Oxygen Species in Living Cells Possibly by Scavenging Peroxyl RadicalsSatoru Sakuma, Yui Kishiwaki, Mayu Matsumura et al.Taxifolin, a naturally occurring dihydroflavonol, has been reported to possess antioxidant activity, whereas there is little information regarding its antioxidant potency as a flavonoid. In the present study, the antioxidant efficacy of taxifolin in living cells was compared to that of catechin, a potent radical scavenger, by using flow cytometry with the redox-sensitive fluorescent dye, 2′,7′-dichlorodihydrofluorescein diacetate. Further, diminishing efficacy … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 18 Oct 2018 · 8,056 accessesView PDF Cite

Research ArticleOpen accessIn the author namesClassification of Breast Tumor in Mammogram Images Using Unsupervised Feature LearningAidarus M. Ibrahim, Baharum Baharudin, Abas Md Said, P. N. HashimahIn this study, we propose a learning-based approach using feature learning to minimize the manual effort required to extract features. Firstly, we extracted features from equally spaced sub-patches covering the input Region of Interest (ROI). The dimensionality of the extracted features is reduced using max-pooling. Furthermore, spherical k-means clustering coupled with max pooling (k-means-max pooling) is compared with well-known feature … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 13 May 2016 · 7,497 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMathematical Analysis of How the Electrical Training Center Site is Affected by Air PollutionBassam A. Al-HelouThe study has come to the result that the monitoring site at the Electrical Training Centre (ETC) at Al-Hashimyeh town is exposed to grave pollution that goes beyond Jordanian standards of the ambient air. It has, indeed, shown that Sulfur dioxide (SO2) exceeds the limits and its seasonal concentration matches forward with the average wind speed. SO2 concentration reaches its … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 3 Sep 2012 · 7,111 accessesView PDF Cite
