The present disclosure relates to an approach by which low-performing turbines may be identified from among a plurality of wind turbines, such as may be present at a wind power plant. The elastic buffer, a FIFO buffer, outputs and writes data according to a reading index and a writing index, respectively. Each bucket is associated with a unique hash value and is implemented as a corresponding balanced tree containing a corresponding set of nodes, with each node storing a corresponding mapping entry. A semiconductor element is mounted as the surface mounting-type electronic component on the pedestal portion. At least one of the two electrode pads is connected to any one of the two mounting terminals on the second diagonal line through a first conductive film provided on an inner wall of the through hole. From the syndrome signal, a desired-data rate is determined for the transmitter.
