With great pleasure, we would like to present the Special Section on Multilevel Converters as an Enabler for Grid Modernization of IEEE Transactions Power Electronics (TPEL), which focuses research and development multilevel converters in modern power grids. On one hand, investigate implementat...
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
This paper proposes a single-phase five-level inverter with a modified pulse width-modulated (PWM)control scheme. The modified pulse width-modulation technique is developed to reduce switching loss.Also, the proposed multilevel inverter can reduce the requirement of power switches compared to aconventional cascaded multilevel inverter. The modes of operation, control signals, and operatingprinc...

In this paper, we investigate the number of 1-factors of a generalized Petersen graph $P(N,k)$ and get a lower bound for the number of 1-factors of $P(N,k)$ as $k$ is odd, which shows that the number of 1-factors of $P(N,k)$ is exponential in this case and confirms a conjecture due to Lovász and Plummer (Ann. New York Acad. Sci. 576(2006), no. 1, 389-398).
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...

در این پایان نامه مرکز ساز جبرهای عملگری استاندارد وh^*- جبرهای نیم ساده را بیان می کنیم. فرض کنیم a یک *h-جبر نیم ساده و t: a -> a یک نگاشت جمعی باشد به طوری که به ازای هر x∈a و بعضی n ≥ 1 داشته باشیم. 2t(x n+1) = t(x)xn + xnt(x) در این صورت t یک مرکزساز چپ و راست است. این پایان نامه بر اساس مقاله ی زیر نوشته شده است: i. kosi-ulbl and j. vukman, on centralizers of standard operator algebras ...
in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...
in the current research, wind energy potential at yazd synoptic stations, which contain wind data with 10 years statistic period and beyond, including yazd synoptic station (1976-2006), tabass (1987-2006), robate poshte badam (1992-2006), bafgh (1993-2006) and marvast (1997-2006), has been studied. wind data were obtained from the recorded data at yazd meteorology organization. the data were re...
