Research ArticleOpen accessIn the abstractDesign Analysis of High-Speed Axial-Flux GeneratorM. Sadeghierad, A. Darabi, H. Lesani, H. MonsefProblem Statement: Axial flux permanent magnet machines are regarded as compact high efficiency generators for micro-turbines employed in the distributed power generation systems. High-speed rotor of the generator causes some designing and modeling problems. Sensitivity analysis tasks of the machine parameters are difficult and completely different in comparison with the problems associated with conventional machines. Approach: This article presents a … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,559 accessesView PDFCite
Research ArticleOpen accessIn the abstractPattern of Survival and Mortality of Mangrove Populations Grown at Al-Jubail Area (Saudi Arabia) of the Arabian GulfAkram Ali, Ahmed Alfarhan, Ernest Robinson, Ibrahim AldjainThe life table and fecundity schedule were produced for [Avicennia marina (Forsk.) Vierh] populations of four habitat types at Al-Jubail area, KSA. These types are sand mounds, salt flats, shoreline and intertidal sites. Survivorship (lx) was least in sand mounds and similar in all other sites. Age-specific-mortality rates (qx) where parallel in the flower bud, flower, fruiting and seedling stages … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 7,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Development of Broadband Inverted E-shaped Patch Microstrip Array Antenna For 3G Wireless NetworkNorbahiah Misran, Mohammad Tariqul Islam, Ng Kok JiunnMicrostrip patch antenna has been received tremendous attention since the last two decades and now it becomes a major component in the development of Smart Antenna System for Third-Generation Wireless Network proposed by the ITU-R under the banner of IMT-2000. Smart antenna consists of an array of antennas associated with it a base-band hardware and control unit (inclusive of the … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractCluster Computing: A Mobile Code ApproachR. B. Patel, Manpreet SinghCluster computing harnesses the combined computing power of multiple processors in a parallel configuration. Cluster Computing environments built from commodity hardware have provided a cost-effective solution for many scientific and high-performance applications. In this paper we have presented design and implementation of a cluster based framework using mobile code. The cluster implementation involves the designing of a server named MCLUSTER … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Cost Long Distance Detector for Explosives and Chemical Analysis by IEC ApplicationGeorge H. Miley, Heinrich Hora, Frederick Osman et al.A radiation source for detecting specific chemicals at several meter distances even behind walls, car doors or other barriers is the application of Million electron Volts (MeV) neutrons from nuclear fusion reactions at such low intensities to avoid any danger for human bodies. The chemical analysis consists in the neutron activation of nuclei emitting then gamma radiation of lines very … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,513 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImproved Model Predictive Control System Design and Implementation for Unmanned Ground VehiclesSai Charan Dekkata, Sun Yi, MA Muktadir et al.Autonomous ground robots autonomously are being used inthe places where it is very hazardous for human beings to reach and operate,such as nuclear power plants and chemical industries. The aim of the researchpresented here is to develop a control system that enables such ground robotsnavigate autonomously with various sensors as the depth camera, 2D scanninglaser, 3D Lidar, GPS, and IMU. … …Journal of Mechatronics and Robotics, Vol. 6, Issue 1 · 27 Oct 2022 · 6,000 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA New Approach for Sub-Channels Assignment in Downlink Fourth Generation Mobile SystemsFakhreddine Khelifa, Abdelaziz SametProblem statement: We proposed a new heuristic method for subchannels allocation problem in the context. Approach: In this system, OFDM transmission method has been used, in order to reduce the effect of multipath fading, OFDMA to achieve multiple access schemes and flexibility in resource allocation. Results: An adaptive method for subchannels allocation is necessary in order to exploit the multiuser … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 6,588 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Fast Series Active Filter using Sliding Mode Control to Correct and Regulate Unbalance Voltage in Three-Phase SystemTheerayuth ChatchanayuenyongProblem statement: A Sliding Mode Controller (SMC) with fast reference voltage generation to correct and regulate unbalance voltage in three-phase system was proposed. Approach: The compensation algorithm was not based on three-symmetrical component decomposition so the controller can yield a fast response that was essential in such a critical real time control work. The reference voltages were fed to the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,221 accessesView PDFCite
