Abstract

Embodiments of the present foundation for wind turbine generators comprise four structural members: a relatively long central hollow pier, several arm grade beams, a continued grade beam and a continued shear key. The central hollow pier positions in the center of the foundation system, arm grade beams are arranged evenly in radial direction and extend from the pier to the continued grade beam. Continued grade beam is arranged circumferentially in outer periphery and the continued shear key is built below it. Arm grade beams have a varied section with the far end embedding into ground. The top of the continued grade beam matches the top of arm grade beams, while the continued shear key embeds deeper into ground. All structural members are constructed of cast-in-place concrete reinforced with rebars, and all connections are fixed and rigid. The present foundation uses the ground to shape and form the structural members, no formwork, backfilling and compaction is needed.

Abstract

A system and method of parallel processing includes a computer system including a first processor, the first processor being a control flow type processor, a second processor, the second processor being a data flow type processor. The second processor is coupled to a second memory system, the second memory system including instructions stored therein in an order of execution and corresponding events data stored therein in the order of execution. A first one of the instructions are stored at a predefined location in the second memory system. The system also includes a run time events insertion and control unit coupled to the first processor and the second processor. The first processor, the second processor and the run time events insertion and control unit are on a common integrated circuit.
