Research ArticleOpen accessIn the keywordsVHDL Modeling, Simulation and Prototyping of a Novel Arbitrary Signal Generation SystemS. A. Abbasi, A. R.M. Alamoud, J.M. Al ShahraniProblem statement: Arbitrary signal generators play an important role in many applications. Several different techniques utilizing both analog and digital approaches are being used for the generation of periodic signals. However, all of them suffer from many drawbacks. In this study, we present modeling, simulation and prototyping of a novel periodic arbitrary signal generation system using FPGAs. The proposed system … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 7,755 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFuzzy 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 PDF Cite

Research ArticleOpen accessAll words, across the recordA Novel Odor Key Technique for Security Applications Using Electronic Nose SystemMahmoud Z. IskandaraniProblem statement: A novel approach to security applications that makes use of odors as password generators is developed and tested. The developed system detects and converts odor signals that are randomly selected to binary signals and then intelligently compares them with previously stored values. Approach: The interface device in question then either opens its interface if comparison is successful or … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,186 accessesView PDF Cite
