Research ArticleOpen accessIn the keywordsDevelopment and Evaluation of a Low-Density Biomass Feeding System for Fluidized Bed GasifiersA. E. Ghaly, A. Ergudenler, S. Alsuhaibani, V. V. RamakrishnanFor efficient operation of a biomass gasifier, the biomass material must be fed continuously to the system. A feeding system for chopped straw and rice husk was designed, constructed and evaluated. It consisted of: a frame, a hopper, an auger, two agitators, a drive system and a power unit. Initial testing showed that wheat straw and rice husk, being highly … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 7 Nov 2013 · 8,045 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFuzzy 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 · 6,882 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynchronization of Chaos Systems Using Fuzzy LogicMohammad Ababneh, Issa Etier, Mahmoud Smadi, Jasim GhaebProblem statement: This study presented a new and systematic method to robustly synchronize uncertain chaos systems. It was derived based on the observer approach for synchronization, where error dynamics was made asymptotically stable around the zero to accomplish synchronization. Approach: This method viewed the synchronization problem as a control problem in order to make use of the literature available in … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,645 accessesView PDFCite
Research ArticleOpen accessIn the keywordsConstrained Response Surface Optimization for a Laser Beam Welding ProcessPongchanun LuangpaiboonProblem statement: On a current operating condition of a laser beam welding process in the hard disk drive industry, it has been found that shear strength of the head support and suspension assembly is slightly higher than customers' specification. This situation leads to an inspection with a large sample size and a high frequency. Shear strength is not only one … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 29 Jan 2011 · 7,372 accessesView PDFCite
Research ArticleOpen accessIn the keywordsField Programmable Gate Array -Based System-on-Chip for Real-Time Power Process ControlAhmed Karim Ben Salem, Slim Ben Othman, Slim Ben SaoudProblem Statement: Nowadays Real-Time (RT) embedded control applications require not just higher performance but more flexibility as well without increasing cost and resources. Approach: In this study we presented a promising co-design and implementation of control solution. We developed flexible solution using software control algorithms coupled with an embedded RT kernel on powerful embedded processor cores, combined with reconfigurable logic … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTransducer for Tension Force Measuring of Strip MaterialsEmad Said AddasiIn winding-up motor drive systems, such as that used in textile industry, it is very important to get a constant tension force for the winding strip material (thread) and to reduce its oscillations. This study recommends a transducer with a special design to be used in the mentioned motor drive systems. By using a piston damper, spring, levers, slider and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,968 accessesView PDFCite

The study was carried out for standstill condition, where precise position information was required for … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Sep 2011 · 9,520 accessesView PDFCite
Review ArticleOpen accessIn the keywordsCriniviruses at the Crossroads of Virology and Agroecology: Molecular Dialogues, Vector Synchrony, and Translational Control Strategies in Crop SystemsMd. Abdullah Al Sabbir, Nabela Akter, Ankita Saha, Md. Motaher HossainCriniviruses, members of the Closteroviridae, illustrate how molecular evolution, vector ecology, and climatic variability converge to determine plant virus emergence and persistence. Although individual genomic and transmission traits are well studied, their cross-scale integration has remained limited. Recent advances in comparative genomics and high-throughput sequencing have revealed that bipartite genome reassortment, recombination hotspots, and quasi-species microdiversity provide the genetic flexibility … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Sep 2026 · 476 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenMicro: A Tool for Generating Microservice Architectures with In-Depth Microservice DesignWilly Kengne Kungne, Georges-Edouard Kouamou, Paul AyangMicroService Architecture (MSA) has become an increasingly popular architectural style for distributed and service-based systems. Despite the various facilities offered by existing frameworks, setting up a microservice architecture remains challenging for developers. Also, configuring all the microservices is time-consuming. Several tools have been proposed for generating microservice architectures. For the most part, these tools focus on the basic configuration aspects, … …Journal of Computer Science, Vol. 21, Issue 3 · 25 Feb 2025 · 7,444 accessesView PDFCite
