According to the present invention, discrete measurements of fluid pressure development are used in optimizing hemodynamics for cardiac resynchronization therapy delivery and multiple chamber cardiac pacing, and in enhancing hemodynamics in the event of a sub-optimal left-side lead placement. In one embodiment, non-J2EE containers are created and deployed on the J2EE server in communication with J2EE containers already deployed on the J2EE server. Furthermore, a wind turbine with such an electrical yaw drive and a method for operating such a wind turbine are described. The automated fault manager can be a rule-based faultperformance management system. The musical key-bed is detachably coupled with a protective cover for providing ergonomic support when, said musical key-bed is not being used. The seal holding part is constituted by a member made of a material having a high degree of shape stability, such as a polyamide, into which glass fibers are added.
