A team of astronomers has identified the engine behind one of the most puzzling classes of repeating cosmic radio signals, ...
Fine-scale exogenous attention within the foveola selectively enhances contrast gain at low-to-mid spatial frequencies while increasing response gain across a broad spatial frequency range.
Researchers developed a daylight electroluminescence imaging method that enables detection of low-energy glass cracks in PV ...
Abstract: Modulation fluctuations will decrease the linear operation range and cause the reduction of dc-link utilization for reduced dc-link capacitance motor drives. In this article, a novel ...
Abstract: This article presents a free-harmonic ac/dc/ac converter structure using a novel modulation approach for asymmetrical cascade H-bridge multilevel inverter and, conventional rectifiers ...
