Influence of structural nonlinearities in stall-induced aeroelastic response of pitching airfoils
(European Assoc Structural Dynamics, 2014-01-01)
Stall-induced vibrations are a relevant aeroelastic problem for very flexible aero-structures. Helicopter blades, wind turbines, or other rotating components are severely inflicted to vibrate in stall condition during each ...

Nonlinear analysis of heart rate variability within independent frequency components during the sleep–wake cycle
(Elsevier Science, 2010-04)
Heart rate variability (HRV) is a complex signal that results from the contribution of different sources of oscillation related to the autonomic nervous system activity. Although linear analysis of HRV has been applied to ...
Black carbon affects the cycling of non-black carbon in soil
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Black carbon (BC) is an important fraction of many soils worldwide and plays an important role in global C biogeochemistry. However, few studies have examined how it influences the mineralization of added organic matter ...
