AN EFFICIENT PHASE-LOCKED LOOP FOR DISTORTED THREE-PHASE SYSTEMS

An Efficient Phase-Locked Loop for Distorted Three-Phase Systems

helen dale samson This 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

Identification of Personalized Chemoresistance Genes in Subtypes of Basal-Like Breast Cancer Based on Functional Differences Using Pathway Analysis.

Breast cancer is a highly heterogeneous disease that is clinically classified into several subtypes.Among these subtypes, basal-like breast cancer largely overlaps with triple-negative breast cancer (TNBC), and these two groups are generally studied together as intra-trac3 a single entity.Differences in the molecular makeup of breast cancers can re
