Research ArticleOpen accessEvery word in the titleDiagnosis of MV Oil Filled Cable Terminations with X-Ray Imaging and Infrared (IR) ThermographyMohd. Rafi Adzman, Ismail Daut, Muzamir Isa et al.A main purpose of doing a diagnostic in cable system including its accessories such as impregnated paper insulated oil filled cable termination is to predict failure before they occur. Those cable and accessories, which are about to fail, can be replaced, thereby reducing the incidence of electrical system failure, thus reducing the electricity outages. This paper presents the work carried … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,679 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA UDDI Search Engine for SVG Federated Medical Imaging Web ServicesSabah Mohammed, Jinan Fiaidhi, Marshal HahnWith more and more medical web services appearing on the web, web service's discovery mechanism becomes essential. UDDI is an online registry standard to facilitate the discovery of business partners and services. However, most medical imaging applications exist within their own protected domain and were never designed to participate and operate with other applications across the web. However, private UDDI … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,008 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMorphological Aspects of the Inferior Frontal Gyrus and its Relations with Brain Hemispheres and Gender: A Study with in vivo Magnetic Resonance ImagingSergio Murilo Georgeto, Munir Antônio Gariba, Luiz Roberto AguiarThis study aims to evaluate the reliability of an anatomy-topographic location method for the anatomical references that form the inferior frontal gyrus and compare the findings of both studied brain hemisphere as well as the genre. Two different pulse sequences-gradient-echo T1 (T1 GRE) and reversal recovery gradient-echo T1 (T1 IR GRE) were used for such purpose. The sample consisted of … …Neuroscience International, Vol. 7, Issue 1 · 22 Mar 2017 · 7,272 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproved 3D Imaging Performance of AFMMd Sohel RanaOver the last three decades the Atomic Force Microscopy (AFM) has played an important role in the field of nanotechnology for imaging and manipulating samples. However, the acquisition of a high-quality imaging performance by an AFM is significantly influenced by its key scanning element called its Piezoelectric Tube Actuator (PTA). In this article, to improve its performance, a multi-input multi-output … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Jan 2020 · 7,295 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSustainability Reporting as a Tool to Improve Transparency towards Stakeholders. Exploring Reporting Practices in the Imaging IndustryLuisa Pulejo, Valeria Naciti, Nicola RappazzoThe complexity that characterizes the international competitive system has enhanced the call for transparent reporting and the dissemination of information concerning social and environmental impact being implemented by firm. Recently, Life Cycle Assessment (LCA) methodology was developed in order to respond to the specific needs to measure the environmental impact of firm’s products and processes in terms of resources consumption … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 2 Jan 2018 · 8,380 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpherical and Improved Helmholtz Coil with High B1 Homogeneity for Magnetic Resonance ImagingSidi M. Ahmed Ghaly, Khalid A. Al-Snaie, Obaidullah Khan MohammadSeveral types of volume RF coils such as Helmholtz pair have been used for Magnetic Resonance Imaging. However, the field uniformity of a coil has always been suffering from a critical issue in imaging accuracy. The presented work is a study and design of spherical and improved radiofrequency Helmholtz coil which produces a high B1 magnetic field homogeneity. This coil … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 22 Dec 2016 · 8,159 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSCANNING ELECTRON MICROSCOPE IMAGING OF AMYLOID FIBRILSEisuke Takai, Gai Ohashi, Ryuichi Ueki et al.This study demonstrated the applicability of Scanning Electron Microscopy (SEM) for the observation of amyloid fibrils without staining. As model specimens, two types of amyloid fibrils with different shapes and chemical compositions were controllably synthesized from hen lysozyme. The apparent fibril widths in the SEM images were considerably larger than the original diameters analyzed by the conventional techniques of Transmission … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 1 Mar 2014 · 10,330 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImaging Spectroscopy and Light Detection and Ranging Data Fusion for Urban Features ExtractionMohammed Idrees, Helmi Zulhaidi Mohd Shafri, Vahideh SaeidiThis study presents our findings on the fusion of Imaging Spectroscopy (IS) and LiDAR data for urban feature extraction. We carried out necessary preprocessing of the hyperspectral image. Minimum Noise Fraction (MNF) transforms was used for ordering hyperspectral bands according to their noise. Thereafter, we employed Optimum Index Factor (OIF) to statistically select the three most appropriate bands combination from … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 28 Oct 2013 · 7,152 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWavelet Statistical Texture Features with Orthogonal Operators Tumour Classification in Magnetic Resonance Imaging BrainR. Meenakshi, P. AnandhakumarTumors medically also called neoplasms are an abnormal mass of tissue resulting from uncontrolled proliferation or division of cells occurring in the human body. If such growth is located in the brain then it is called as brain tumor. Identification of such tumors is a major challenge in the field of medical science. Early identification of tumors prove to be … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 6,600 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Electrode Spacing and Inversion Techniques on the Efficacy of 2D Resistivity Imaging to Delineate Subsurface FeaturesAdiat Kola Abdul-Nafiu, Mohd. Nawawi Mohd. Nordin, Khiruddin Abdullah et al.In this study, the effect of the choice of appropriate electrode spacing and inversion algorithms on the efficacy of 2D imaging to map subsurface features was investigated. The target being investigated was the drainage concrete pipe buried at approximately 0.3 m into the subsurface. A profile perpendicular to the strike of the pipe was established. 2D resistivity data was separately … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 14 Jan 2013 · 7,727 accessesView PDFCite
