In the actual power system three-phase voltages are distorted and asymmetric and contain a large number of negative sequence components. Traditional ip-iq method which detect harmonic currents based on instantaneous reactive power theory will be inaccurate, so the positive sequence voltage component of A-phase need be extracted. Improved instantaneous symmetrical components structured a rotary phases...
Sixteen pairs of two-component regulatory systems are identified in the genome of Staphylococcus epidermidis ATCC12228 strain, which is newly sequenced by our laboratory for Medical Molecular Virology and Chinese National Human Genome Center at Shanghai, by using bioinformatics analysis. Comparative analysis of the twocomponent regulatory systems in S. epidermidis and that of S. aureus and Bacillus subtilis...
