Review of Daqing＇s Technologies in 10th Five-Year Plan Period

During the 10^th Five-Year Plan Period, Daqing Oil Field entered the late high water-cut period with the reserve production ratio in imbalance. The oil field development became more and more difficult owing to the inadequate substitute resources. Daqing Oil Field Company has made a series of important and new technological achievements to solve those bottlenecks. The oil field has cumulatively achieved a total of technological results, of which eight items are at the State level, 96 items at the provincial and ministerial level, and 1009 items granted with the patent rights. The oil field has developed a family of exploration and development technologies which are world-leading and self-developed with an independent IPR.     

POWER OPTIMIZATION OF FINITE STATE MACHINE BASED ON GENETIC ALGORITHM

Using state assignment to minimize power dissipation and area for finite state machines is computationally hard.Most of published results show that the reduction of switching activity often trades with area penalty.In this paper,a new approach is proposed.Experimental results show a significant reduction of switching activity without area penalty compared with previous publications.
