Modulation in CRI Due to Solar-Interplanetary Causes during 1996–2018
Abstract: AbstractSolar outputs and their variations are responsible to produce modulation in cosmic ray intensity (CRI) both on short-term as well as on long–term basis. It is seen that sunspot number; 10.7 cm sun oriented radio transition, coronal mass launches (CMEs) and sunlight based flares are the causal connect to sun oriented movement (SA). In addition, coronal mass discharges are related with an assortment of interplanetary plasma and field aggravations. In …

Damping Techniques for Controlling Edgewise Vibration of Wind Turbine Blades
Abstract: AbstractEdgewise vibrations with low aerodynamic damping are of particular concern in modern multi-megawatt wind turbines, as large amplitude cyclic oscillations may significantly shorten the life-time of wind turbine components, and even lead to structural damages or failures. In this paper, five types of damping methods are studied. The tuned liquid dampers utilize the sloshing motion of the fluid to suppress structural vibrations and become a natural candidate for damping vibrations …
