Symmetrical and Asymmetrical Multilevel Inverter Structures with Reduced Number of Switching Devices
Background and Aim: Changes in the position of the scapula due to its multiple roles, including acting as a muscle binding site and stabilization in this area can reduce the physiological and biomechanical efficiency of the shoulder, which ultimately increases shoulder injury. Therefore, the purpose of this study was to compare the functional stability of shoulder girdle between asymmetric and ...
Background The latest data show that psoriatic arthritis (PsA) patients (pts) with asymmetrical sacroiliitis (SI) have clinical and genetic features which are considered typical for PsA (1). Objectives To analyze comparative characteristics of pts symmetrical SI. Methods 287 (M/F–147/140) according to CASPAR criteria were examined. Data was collected from 6 rheumatology clinics the Russian Fede...
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
Scientists have been attracted by polymersomes as versatile drug delivery systems since the last two decades. Polymersomes have the potential to be versatile drug delivery systems because of their tunable membrane formulations, stabilities in vivo, various physicochemical properties, controlled release mechanisms, targeting abilities, and capacities to encapsulate a wide range of drugs and othe...
This paper presents asymmetrical cascaded multilevel inverter (ACMLI) approach for high voltage and high power output applications. It is based on the cascade connection of the H-bridge inverter cells. Now ever by the supplies which are in GP with different ratios like 2,3,etc. The proposed configuration is shown for 27 level inverters with symmetrical step control, optimization angle control a...
With the rapid growth in penetration rate of mobile devices and surge demand for data services, small cells backhaul networks have become critical focus next-generation network development. Backhaul requirements within current wireless are almost asymmetrical, with most traffic flowing from core to handset, but 5G will require more symmetrical capability. The deployment placement transceivers c...
lamine (PE) and red cell 14C, reflecting cytoplasmic hemoglobin, were measured sequentially in rats given transfusions of doubly-labeled reticulocytes. With reticulocytes from normal rats there was a small decline in the levels of both the membrane and the cytoplasmic labels; the changes were almost arellel, although loss of membrane PE2P exceeded that of ‘4C to a small extent. By contrast, wit...
