The dual PWM variable frequency speed regulation system applied to scraper conveyors, coal shearers and other mechanical equipments needs to be installed a filter on the rectifier grid-side to suppress harmonic currents.The existing LCL filter design method relies on experience and has low efficiency, and the damping loss problem is not considered
The organosilicon derivatives of 2 -[ 1 -( 2 -furayl)ethyledene]sulphathiazole with organosilicon chlorides have been synthesised and characterized on the basis of analytical, conductance, and spectroscopic techniques.Probable trigonal bipyramidal and octahedral structures for the resulting derivatives have been proposed on the basis of electronic,
A novel method is proposed for estimation of the mutual coupling matrix of an antenna array.The method extends previous work by incorporating an unknown phase center and the acupatch element factor (antenna radiation pattern) in the model, and treating them as nuisance parameters during the estimation of coupling.To facilitate this, a parametrizati
Introduction: After solid organ transplantation, patients require lifelong immunosuppressive medication, increasing crystal beaded candle holder susceptibility to COVID-19.We evaluated the clinical outcomes of heart transplant recipients in patients with COVID-19.Methods: We enrolled twenty-two COVID-19 cases of adult heart transplantation from Feb
