In big data era, the changes of data form, data acquisition and data exchange have increased the difficulty in processing data credibility and isomerism, as a result, it ' s difficult to solve the critical knowledge bottleneck of service combination scheduling model. Service scheduling process, analysis of credibility and functional data acquisition is very important, further more, most of the current...
This paper aims to analyze the applied hybrid controlled three-phase grid-connected inverter for marine current power generation system used in distributed generation. As inverter is a key part of the grid-based system, grid-connected technology plays an important role in the distributed generation to meet the stricter grid interconnection standards. In order to improve the power quality and strengthen...
Ultrasound tissue harmonic signal generally provides superior image quality as compared to the linear signal but with limited penetration and the sensitivity due to low signal-to-noise ratio (SNR). The method of third harmonic (3f0) transmit phasing can improve the tissue harmonic SNR by transmitting at both the fundamental and the 3f0 frequencies to provide mutual enhancement between the second harmonic...
Golay-encoded excitation in combination with the third harmonic (3f0) transmit phasing is examined for both signal-to-noise ratio (SNR) and contrast-to-tissue ratio (CTR) improvements in harmonic imaging of contrast microbubbles. To produce the cancellation pair of tissue harmonic signal in 3f0 transmit phasing, the phase of the bit waveform is properly designed for both the fundamental and the 3f...
