Abstract: A wind turbine includes a rotor comprising multiple blades mounted on a hub, MIMUs mounted on each blade for sensing parameter signals thereof, and a control system. The control system includes a wind speed calculation unit, a wind shear calculation unit, a pitch angle compensation command calculation unit, and a pitch control unit. The wind speed calculation unit is used for calculating wind speeds at the blades based at least on the sensed parameter signals. The wind shear calculation unit is used for calculating a characteristic shear exponent based at least on the calculated wind speeds. The pitch angle compensation command calculation unit is used for calculating pitch angle compensation commands of the blades based at least on the calculated characteristic shear exponent. The pitch control unit is used for adjusting the pitch angles of the blades based on the calculated pitch angle compensation commands.

Abstract: A data structure is provided for storing network contact information based on an array of physical memory locations. Virtual vectors are constructed for each source, wherein each element in each virtual vector is assigned to a corresponding physical memory location within the array. The physical memory locations are shared between the virtual vectors uniformly at random so that the noise introduced by sharing can be predicted and removed. A method for storing network contact information is also provided in which a hash function is performed using the address of a source host to find a virtual vector for holding information about the source host. A second hash function is performed using the address of a destination host to find a virtual memory location, within the virtual vector, for holding information about the destination host. Finally, information is stored at a physical memory location assigned to the virtual memory location.
