INTRODUCTION The aim of this study was to determine if antibiotic or anti-inflammatory medications lower serum prostate-specific antigen (PSA) in the presence or absence of inflammation in the prostatic secretions of patients with PSA levels between 2.5 and 10 ng/ml and normal digital rectal examinations (DRE). MATERIALS AND METHODS Patients with PSA(More)
This contribution investigates three-phase four-level FLC based indirect frequency converter supplied from a 6kV AC-grid. It describes proposed active voltage balancing control of both output voltage-source inverter and input active rectifier with PD-PWM. The results are verified by experiments made on down-scale prototype of converter of rated power of(More)
Rao-Blackwellied particle filter is a stochastic filter combining Kalman filters with particle filters. It is suitable for models that could be decomposed into linear and nonlinear part. Since the conditionally linear part can be solved by the Kalman filter, the sequential Monte Carlo is run only on the non-linear subspace. The resulting algorithm is a(More)
This paper presents three-phase four-level FLC based electric motor drive for mining application supplied directly from a 6 kV ac-grid. It describes complete control algorithms of the drive with active voltage balancing control. The proposed control is verified by experiments carried out on down-scale drive prototype of rated power of 35 kVA.
