In this paper, we proposed a new two-dimensional (2-D) wavelet-based electrocardiogram (ECG) data compression algorithm. A 1-D ECG data is first segmented and aligned to a 2-D data array, thus the two kinds of correlation of heartbeat signals can be fully utilized. And then 2-D wavelet transform is applied to the constructed 2-D ECG data array. A modified(More)
[1] Inversion techniques applied to GPS‐LEO radio occultation data allow the retrieval of accurate and worldwide‐distributed refractivity profiles, which, in the case of the ionosphere, can be converted into electron densities providing information regarding the electron content distribution in this atmospheric region. In order to guarantee the accuracy of(More)
Considering the optimal operational characteristics of a grid connected wind turbine, controllers are designed based on the dynamical model of the wind turbine system. In the higher wind speed region, the neural network controller of the turbine blades pitch angle is presented to confine the excess wind energy entering the generation system in order to(More)
