    Abstract: An apparatus and system for counteracting wind gusts and other high load situations in a wind turbine includes the use of one or more gust counteracting devices configured to extend an air deflector outwardly from a surface of a turbine rotor blade. The air deflector may subsequently be retracted into the rotor blade once the wind gust has subsided or once the load falls below a certain threshold. Mechanisms for extending and retracting the air deflector may include pneumatic or hydraulic systems and/or electromechanical devices. Air deflectors are generally configured to normalize air flow around the rotor blade so that the risk of potential damage to components of the wind turbine is minimized. In one arrangement, the gust counteracting device may be located at a leading section of the turbine blade. Additionally or alternatively, the device may be modular in nature to facilitate the removal and replacement of the device.

    Abstract: A computer-implemented method for processing documents in a multi-lingual document database includes generating an initial ranking of retrieved multi-lingual documents using an information retrieval system and based upon a user search query, and processing vocabulary words based upon occurrences thereof in at least some of the retrieved multi-lingual documents. Respective relevancies of the vocabulary words based on the occurrences thereof and the user search query are generated. A re-ranking of the retrieved multi-lingual documents is generated based on the relevancies of the vocabulary words.
