Intelligent management to the large scale Ad Hoc network has already become a kind of trend, and the clustering algorithm is the key. This article examines formula factors and their mutual relations of EWCA algorithm weights. After considering complex external environment of nodes, digging factors of network, it proposes an algorithm that calculates, sets(More)
According to the large overshoot and high static error of traditional DC bus voltage control, Active Power Filter (APF) DC bus system model is built on the basis of analyzing of APF DC bus voltage control theory, and a new DC bus voltage control method based on combination of PI control and fuzzy control is proposed, then an experimental prototype is built.(More)
Unique and stable reference point is essential for registration and identification in automated fingerprint identification systems. Most existing methods for detecting reference points need to scan the fingerprint image or orientation field pixel by pixel or block by block to confirm a candidate reference point. The inherent complexity of this process makes(More)
