This paper describes methods for explanatory and illustrative visualizations used to communicate aspects of Einstein's theories of special and general relativity, their geometric structure, and of the related fields of cosmology and astrophysics. Our illustrations target a general audience of laypersons interested in relativity. We discuss visualization(More)
Active power filters have been used to eliminate current harmonics generated by nonlinear loads, because such loads decrease the power quality, but with the growing use of renewable energy sources interconnected to the grid is possible integrate the function of the active power Alter to the grid-connected photovoltaic-system, the functions in a single(More)
Transformerless inverters are widely used in grid-tied photovoltaic (PV) generation systems, due to the benefits of achieving high efficiency and low cost. The transformerless photovoltaic inverter may generate a leakage current between the inverter and the grid, through a parasitic capacitance. This leakage current will cause a low efficiency a distortion(More)
In this application paper, we report on over fifteen years of experience with relativistic and astrophysical visualization, which has been culminating in a substantial engagement for visualization in the Einstein Year 2005 - the 100/sup th/ anniversary of Einstein's publications on special relativity, the photoelectric effect, and Brownian motion.
