Research ArticleOpen accessAll words, across the recordGraph Representation for Secondary System of Pressurized Water Reactor with Autocatalytic Set ApproachAzmirul Ashaari, Tahir Ahmad, Mustaffa Shamsuddin et al.The pace of nuclear reactor development in increasing and this is caused by the high authoritative ordinance of electricity from the end users. Furthermore, maintaining and controlling nuclear reactor operation are high priorities due to safety reasons. The aim of this paper is to describe the secondary system of Pressurized Water Reactor (PWR) system by using graph. Furthermore, fuzzy graph … …Journal of Mathematics and Statistics, Vol. 11, Issue 4 · 30 Dec 2015 · 7,062 accessesView PDFCite
EditorialOpen accessAll words, across the recordAre we Able to Harness the Immunomodulatory Power of Cytokines for Novel Autoimmune Disease Treatments?Giuseppe Nocentini, Graziella Migliorati, Carlo RiccardiSince the end of the 1970s, interleukin 2 (IL-2) has been known as a key player in T cell expansion/activation (Watson et al., 1980). In the late 1980s, some groups used IL-2 to stimulate the immune systems of tumour patients (Jacobs et al., 1986). The idea seemed brilliant and several attempts were made, but the results were disappointing (Lim et … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 2 · 22 Oct 2015 · 7,625 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFuzzy Inference System Based Power Factor Correction of Three Phase Diode Rectifier Using Field Programable Gate ArraySundar Rajan Giri Thulasiraman, Christober Asir RajanThis study describes a novel method in improving the input current total harmonic distortion as well as power factor of a three-phase diode rectifier circuit. In this method, three bidirectional switches comprising MOSFET and four diodes are used across the three-phase supply and load. In a three-phase rectifier only two diodes conduct at any given time. As a result, the … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 6,877 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordParticle Swarm and Neural Network Approach for Fault Clearing of Multilevel InvertersR. M.S. Parvathi, M. SivakumarThis study presents a machine learning technique for fault diagnostics in induction motor drives. A normal model and an extensive range of faulted models for the inverter-motor combination were developed and implemented using a generic commercial simulation tool to generate voltages and current signals at a broad range of operating points selected by a Particle Swarm Optimization (PSO) based machine … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,486 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Fuzzy Logic Based Power Control for Wideband Code Division Multiple Access Wireless NetworksN. Mohan, T. RavichandranProblem statement: Resource management is one of the most important engineering issues in 3G systems where multiple traffic classes are supported each being characterized by its required Quality of Service (QoS) parameters. Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning. Efficient CAC is necessary for the QoS provisioning in … …Journal of Computer Science, Vol. 8, Issue 8 · 4 Aug 2012 · 6,755 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Wireless Sensor Node Supporting Various Powers Supply and Communication MethodsStefan Gruber, Hannes Reinisch, Hartwig Unterassinger et al.Problem statement: This study presents a wireless sensor node dedicated for in-tire pressure and temperature monitoring. Additional features set it apart from the many different systems available on the highly competitive market. State-of-the-art implementations are mounted on the rim of a tire. Here the sensor node will be mounted on the inner liner of the tire. By moving the sensor … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 8,032 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPower Quality Analysis in 6 MW Wind Turbine Using Static Synchronous CompensatorR. Valarmathi, A. ChilambuchelvanProblem statement: An inherent problem with wind turbine power generation systems is the low power quality due to intermittent power generation in these systems. This not only affects the power generation but also the grid it is connected to. Approach: In this study a configuration consisting of a 6MW Wind Farm based on conventional Fixed Speed Induction Generator is analyzed. … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 23 Nov 2011 · 7,232 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
Research ArticleOpen accessAll words, across the recordHarmonics Phase Shifter for a Three-Phase System with Voltage Control by Integral-Cycle Triggering Mode of ThyristorsI. Badran, A.L. Mahmood, M.T. LazimIn integral-cycle triggering mode of voltage control, subharmonic as well as higher order harmonic components are generated in the load voltage waveforms of a three-phase system. These harmonic components are found to be unbalanced in phase displacement. The correction of the unbalanced phase displacement angles of a particular subharmonic or higher order harmonic for this type of triggering is investigated … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,110 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordReed Solomon Coding for Frequency Hopping Spread Spectrum in Jamming EnvironmentOthman Sidek, Abid YahyaFrequency hopping spread spectrum with noncoherent M-ary frequency shift keying system is considered. In this study Reed Solomon codes RS (255, 223) are employed in a standard error correction role to provide some Anti-Jamming (AJ) capability with 8-bit symbols.
