The effects of the oxygen vacancies on the microscopic potential distribution and macroscopic potential averaged over one period around the defect for silicon dioxide have been investigated via first-principles calculations. ...

One of the key challenges in next generation access networks based on Ethernet Passive Optical Network (EPON) technology is Dynamic Bandwidth Allocation (DBA) process. In this paper we have proposed ‘Parnian', a two-stage ...

This paper presents a new technique based on model reference adaptive system (MRAS) observer for sensorless speed control of Two-Phase Induction Motor (TPIM). The MRAS identification is performed by means of comparison of ...

In this paper a new structure for the MLF (Multi Loop Feedback) Gm-C group of filters is presented, granting the advantages of both current-mode and fully balanced topologies to the conventional structure of the group. The ...
