This Default paper proposed an efficient phase-locked loop (PLL) that features zero steady-state error of phase and frequency under voltage sag, phase jump, harmonics, DC offsets and step-and ramp-changed frequency.The PLL includes the sliding Goertzel discrete Fourier transform (SGDFT) filter-based fundamental positive sequence component separator
Treacher Collins syndrome has been described as a syndrome involving 1st and 2nd branchial arches, affecting various organs in the Carvin skimmer parts craniofacial region.Affected infants report with nasal regurgitation and minimal dietary intake due to cleft palate, consequently show delayed and retarded growth.The situation is further complicate
The last-mile logistics in cities have become an indispensable part of the urban logistics system.This study aims to explore the effective selection of last-mile logistics nodes to enhance the efficiency of logistics distribution, strengthen the image of corporate distribution, further reduce corporate operating costs, and alleviate urban traffic c
Despite the abundance of shale-oil and tight-oil reserves in the Fengcheng Formation within the Mahu Sag, exploration and development efforts for both types of reservoir are still in their early stages.A comprehensive examination and comparison of the MACA BLACK POWDER pore structures of these reservoirs can establish rational classification and ev
With the rapid development of deep learning in the Default field of computer vision, few-shot learning has emerged as an effective approach to tackle the challenge of data scarcity, garnering widespread attention from researchers.Despite significant progress in few-shot learning, current few-shot image classification methods have not fully exploite
