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 · 6,877 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimized High Frequency Signal Injection Based Permanent Magnet Synchronous Motor Rotor Position Estimation Applied to Washing MachinesOlfa Bel Hadj Brahim Kechiche, Houda Ben Attia Sethom, Hafedh Sammoud, Ilhem Slama BelkhodjaProblem statement: This study investigates a novel optimized scheme of a High Frequency Signal Injection (HFSI) based sensor less technique in order to carry out a precise and robust rotor position error estimation of a Permanent Magnet Synchronous Motor (PMSM) drive designed for washing machines. 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 · 9,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of E-Service Quality Dimensions on Repurchase Intention for Digital Products: The Role of Satisfaction and Trust Among Young Consumers in Chattogram City, BangladeshMohammad Toufiqur Rahman, Ashfia Khan Ema, Muhammad Abdul AhadThis study aims to analyze the digital product marketplace in Chattogram, Bangladesh by investigating the influence of e-service quality dimensions, namely reliability, responsiveness, security, and convenience, on mobile-first young consumers' satisfaction, trust, and repurchase intention. Using repurchase intention as a primary indicator of digital loyalty, the study contributes to existing literature by considering theories such as the Expectancy-Confirmation Theory, Relationship … …Journal of Computer Science, Vol. 22, Issue 8 · 18 Aug 2026 · 1,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractChanges in the Composition and Diversity of Pasture Grass Due to the Influence of Grazing in the Steppe Zone of Northern KazakhstanAliya Baitelenova, Balzhan Akhylbekova, Meisam Zargar et al.Overgrazing poses a serious threat to the sustainability of steppe pasturelands in Northern Kazakhstan, where intensifying livestock pressure drives significant changes in vegetation composition, species diversity, and soil fertility. This study investigated the effects of grazing intensity on pasture vegetation and chestnut soil properties in the Zhaksyn district of the Akmola region. Field surveys were conducted in July-August 2024 using … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 31 Mar 2026 · 1,338 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Synchronous Reference Frame Controlled Fuzzy Logic Based Distribution Static Compensator to Enhance Distribution System Power QualityRekha Sampath, Lokesh Mallaiah, Ashwini A V et al.The demand for enhanced power quality in distribution systems has increased due to the widespread utilization of various AC loads, including rectifiers, inductive loads, and variable speed drives. When these nonlinear loads are combined with renewable energy sources, harmonics are introduced in the system. These can affect the way other equipment in the network works and leave the system vulnerable … …Journal of Computer Science, Vol. 22, Issue 2 · 27 Feb 2026 · 1,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractConvergence of GenAI and RPA: A Digital Heaven in Supply Chain Optimization ProcessSaurabh A. Pahune, Zahid Akhtar, Manoj Chandrasekharan et al.One of the most groundbreaking advances in the field of intelligent automation is the merging of Generative Artificial Intelligence (GenAI) and Robotic Process Automation (RPA). This combination unlocks previously unachievable capabilities in automation. RPA (software bots) improves speed and operational efficiency by automating rule-based tasks, Standard Operating Procedures (SOPs), and repetitive workflows. At the same time, it minimizes manual labor … …Journal of Computer Science, Vol. 21, Issue 12 · 8 Feb 2026 · 2,040 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Construction of a Smart Meter with Embedded Web PortalDavid Mike-Ewewie, Ayodele Ifijeh, Victoria Oguntosin et al.The absence of the necessary infrastructure to make an accurate and precise collection of data when compared to the first-world countries in the power industry is great. Due to that, the need for the deployment of smart meters has increased in order to offer consumers and customers awareness of their electricity usage, helping them lower their total energy footprint. In … …Journal of Computer Science, Vol. 20, Issue 8 · 14 Jun 2024 · 5,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractConceptual Archaeology of a Temporal Place: Albert and Kessler (1976) Applied to Chacma Baboons (Papio ursinus)Lucy Baehren, Susana CarvalhoAlthough leave-taking in non-human species has been preliminarily investigated in a few species, the mechanisms driving encounter ends remain unstudied. In 1976 Albert and Kessler published a landmark paper, outlining theories about what drives social encounter ends and providing a framework of internal and external motivations leading to separation. This framework has been underused in aiding our understanding of how … …Journal of Social Sciences, Vol. 20, Issue 1 · 21 Mar 2024 · 6,227 accessesView PDFCite
Research ArticleOpen accessIn the abstractGreen Leadership as an Emerging Style for Addressing Climate Change Issues in SchoolsWahab AliThis paper attempts to investigate the concept of green leadership towards creating a greener environment through addressing issues of climate change and global warming. This initiative has been undertaken because principals take on a leading role in climate change education. As such an exploratory study was undertaken aimed at eliciting the views of principals about climate concepts and their opinions … …Journal of Social Sciences, Vol. 15, Issue 1 · 22 Jun 2019 · 8,307 accessesView PDFCite
