The paper presents a novel effective electric energy conservation device for power quality enhancement as well as damping switching-load transients. The modulated power filter and switched capacitor compensator device (MPFC-green plug) is developed by for the 3 phase, 4 wire utilization loads. A novel tri loop dynamic error driven switching controller is(More)
This paper presents a novel tool based on Microsoft Excel for analyzing radial distribution systems. New algorithms are developed to draw the network diagrams graphically within the spreadsheet, once the input data is available. A 9-bus radial distribution system is considered for demonstrating the features of the developed tool. Computations and results(More)
Residential energy consumption patterns are different from region to region and from country to country. Several countries carry energy audit studies in various segments - industry, commercial, building and domestic with different objectives. This paper presents a case study of home energy audit exercise carried out in Phuentsholing, Bhutan to analyze the(More)
Heart and vascular endothelial cells from human pluripotent stem cells are of interest for applications in cell therapy and cardiovascular disease. Differentiation protocols are now sufficiently refined that production of cardiomyocytes, endothelial-and smooth muscle cells is fairly efficient and reproducible. Genetically marked hESCs have been produced in(More)
