This paper is proposed a novel topology of a single phase grid connected inverter in order to conquest the common mode leakage current. There are many topologies presented so far, But none of them has the efficiency more than 98 percent. In this paper, a modern configuration is presented that, not only delete the common mode leakage current, but also increase the efficiency and power density an...
a new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. we use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. then, we linearized this identified model at each sampling time to have an approximate linear time varying system. in order to stabilize...
In this paper, we discuss the calibration procedure and performance of the poly-heater measurement technique for device characterization and reliability issues. We put a particular emphasis on the accessible temperature range, the heating and cooling dynamics, as well as on the impact of temperature gradient between the heater, device, and thermo chuck. In this context, the poly-heater techniqu...
In a data center, servers communicate with each other to store and handle a large amount of data. Thus, the network within a data center affects the performance of the data center; the lack of bandwidth between servers increases the time to obtain the required data from the other servers. The energy consumption is also one of the important problems in a data center. The energy consumed by the d...
BACKGROUND Biologic drugs are expensive treatments used in rheumatoid arthritis (RA). Switching among them is common practice in patients who have had an inadequate response or intolerable adverse events. The National Institute of Health and Clinical Excellence (NICE) UK, which aims to curtail postcode prescribing, has provided guidance on the sequential prescription of these drugs. This study ...
