Abstract: A method for computer-implemented prediction of power production of a wind farm includes: obtaining first weather forecast data for a first time period, obtaining first power production data for the first time period, obtaining second weather forecast data for a second time period; determining second power production data for the second time period by processing the first weather forecast data, the first power production data and the second weather forecast data by a trained recurrent neural network, where the first weather forecast data, the first power production data and the second weather forecast data are fed as a digital input to the trained recurrent neural network and the recurrent neural network provides the second power production data as a digital output, the second power production data being a prediction of power production for the second time period.

Abstract: The invention relates to items which are used to protect documents, such as folders, ring binders, clip binders or similar. The inventive items are provided with flaps or pockets on one or both of the inner faces thereof. Moreover, said items comprise a securing device or element which protects the documents contained therein and holds same in place.
