Web20 mei 2016 · Evaluation and non-destructive identification of stress-induced cracks or failures in metals is a vital problem in many sensitive environments, including transportation (steel railway tracks, bridges, car wheels, etc.), power plants (steam generator tubing, etc.) and aerospace transportation (landing gear, aircraft fuselages, etc.). There are many … WebMagnetic storms are caused by changes in the currents flowing near the Earth, particularly by the enhanced ring current. The ring current dynamics is described through the energy balance equation, where a key role is played by the decay time parameter τ . Two kind of models depending on diverse geophysical parameters have been introduced for this …
