摘要:The development of wind turbine technology has led to higher and larger wind turbines with a higher sensitivity to dynamic effects. One of these effects is the aerodynamic damping, which introduces favorable damping forces in oscillating wind turbines. These forces play an import...

摘要:Abstract(#br)The presented investigations aim to suggest more realistic models to predict the dynamic behavior of wind turbine structures. Two key issues are addressed: the aerodynamic damping and the cross-wind vibrations.(#br)Based on experimental studies in the boundary layer ...

摘要:Abstract(#br)In order to improve the structural design of tubular and lattice towers for wind turbines, and in order to allow for detailed structural optimizations, a methodology is desirable which allows for quick and reliable considerations of the complex dynamic load situation...

摘要:Summary(#br)The author reports on a exploratory study on the ways Muslim immigrants to Netherlands use their religious background to create meaning in the practice of everyday life. Meaning is defined as the relief of a condition of anomie. Interview data from 76 Moroccan me...

摘要:A positive correlation between religious participation and subjective well-being has been demonstrated frequently in empirical research among Christian believers. In this article, we demonstrate that this relationship also exists in a Muslim religious context. Data are presented,...
