Research ArticleOpen accessIn the author namesFuzzy 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 PDF Cite

Research ArticleOpen accessIn the author namesSM-SCAM YOLO: Enhancing Object Detection with Multi-Scale Module and Spatial Channel Attention MechanismShanmuga Sundari Mariyappan, Kayalvizhi Mohan, K. B. K. S. DurgaDetecting tiny objects remains a significant hurdle in computer vision, primarily due to scale variation, occlusion, and the loss of detail in low-resolution features. Although YOLO-based detectors are popular for their speed and efficiency in real-time tasks, they often struggle with accurately identifying small objects because of information loss during downsampling. This study introduces an improved YOLO-based model that integrates … …Journal of Computer Science, Vol. 21, Issue 6 · 12 Jun 2025 · 3,930 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDesign and Analysis of Bipolar Plate for 500w Pem Fuel Cell StackA. Kalaiyarasan, C. Srinivasan, S. SundaramThe PEM Fuel Cell (PEMFC) performance depends on the operating parameters like temperature, pressure, stoichiometric ratio of reactants, relative humidity, back pressure on anode and cathode flow channels, and the design parameters like rib width to channel width (L:C), channel depth, shape of the flow channel and number of pass on the flow channel. The voltage and power produced by … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 13 Jan 2018 · 7,899 accessesView PDF Cite
