This work proposes a novel combined approach for reducing the storage capacitances in off-line high power factor LED drivers.The proposal is to combine converter integration (power factor correction plus power control stages sharing a common switch) with photometrical constraints on the maximum allowable LED current ripple.An experimental setup was
Hemorrhagic fever with renal syndrome (HFRS) has been a major concern for public health in different countries of the Euroasian continent for decades.In 1970s the disease was associated with newly discovered viruses that were to become new members (under the genus Hantavirus) of the family Bunyaviridae.During a deadly outbreak of pulmonary syndrome

As part of the Ultra High Aspect Ratio Wing Advanced Research and Designs (U-HARWARD) project, funded by CS2JU, various gust load alleviation (GLA) technologies have been developed and studied.GLA plays a crucial role in the development of new generation ultra-high aspect ratio wings (UHARWs), as it reduces gust loads, thereby decreasing the struct
