For special conditions pumping, in order to facilitate the measurement of energy-saving and efficient pumping efficiency motor, designed and developed in the laboratory simulation of pumping dynamic load control system using DSP data acquisition system, the motor is calculated in real time by the FFT algorithm power, combined with the PC software, the use of differential forward PID algorithm to control...
In this paper, we study overload handling for frequent-pattern mining in online data streams. For a mining system with an e-deficient synopsis based algorithm, we propose a load shedding scheme to deal with the overload situation. The heavy workload of the mining algorithm lies mostly in the great deal of itemsets which need to be enumerated and counted by the mining algorithm. Therefore, our proposed...
In the storage of the ordered tree, for two weaknesses (the XML document is large and the space-efficient LOUDS bit-string can only describe static trees), the space-efficient-tree package format based on the LOUDS bit-string is proposed. This package format can not only store ordered trees space-efficiently, but also achieve the dynamic operations of ordered trees. In the end, a variety of common...
We present a new clustering algorithm (NPSK algorithm), based on the modification of the newly developed point symmetry-based K-means algorithm (PSK algorithm). Not only the proposed NPSK algorithm is suitable for almost all test data sets used by Chung and Liu for PSK algorithm , the proposed NPSK algorithm is also suitable for the case where the symmetric property of the data set is not so distinct...
