The positioning and orientation system consists of three-axis generating coils and three-axis sensor coils in quasi-static magnetic field. The three-axis generating coils are fixed orthogonally and excited by the alternating current (AC) signals with different frequencies. They create the magnetic field that is equivalent to that generated by three orthogonal magnetic dipoles. Using the amplitude...
A continuous incremental updating technique is proposed for efficient maintenance of the mining association rules when new transaction data are added to a transaction database. FP-growth algorithm can mine the complete set of frequent patterns by pattern fragment growth. To efficient maintenance of the mining association rules, we improve the FP-growth algorithm in three aspects: 1) an optimization...
