Research ArticleOpen accessEvery word in the titleApplying Packet Generator for Secure Network EnvironmentMohammed N. Abdul Wahid, Zuriati Ahmed ZulkarnainProblem statement: Viruses and hacker attacks typically generate a recognizable pattern or “signature” of packets. Most of Network Traffic Analyzer can identify these packets and alert the administrator to their presence on the network via email or page. Approach: Most traffics analyzers let you set alarms to be triggered when a particular pattern is seen. Results: Some network traffic analyzers … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,264 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynchronous Generator Disturbance Provoked by Induction Motor StartingS. P.Y. Santos, E. Delbone, E. F. Carvalho, L. N. MartinsProblem statement: This study presented an alternative procedure for the starting of large Inductions Motors (IM) in isolated generation systems. Approach: In isolated generation systems on stand-by or base load, the starting of the IM provoked sags frequently beyond the ability of the other consumers in the plant to stand. Manufacturers' solutions always recommend a supersized generator to decrease transient … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 6,939 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConverting of Matter to Nuclear Energy by AB-GeneratorAlexander BolonkinProblem statement: Researcher offered a new nuclear generator which allowed to convert any matter to nuclear energy in accordance with Einstein equation E = mc2. The method was based upon tapping the energy potential of a Micro Black Hole (MBH) and Hawking radiation created by this MBH. Researcher did not meet the idea and its research in literature to develop … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,626 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign 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 accessEvery word in the titleFuzzy Based Digital Automatic Voltage Regulator of a Synchronous Generator with Unbalanced LoadsA. Darabi, S.A. Soleamani, A. HassanniaVoltage stability and power quality of the electrical systems depend on proper operation of the Automatic Voltage Regulators (AVR) of generators. Nowadays, design technology of the AVRs is being broadly improved. According to wide range operating conditions of the generators and loads, the fuzzy AVRs are going to be the modern type of regulators, particularly, for the genset alternators operating … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,602 accessesView PDFCite
