gorik ooms recently made a strong case for considering the centrality of normative premises to analyzing and understanding the underappreciated importance of the nexus of politics, power and process in global health. this critical commentary raises serious questions for the practice and study of global health and global health governance. first and foremost, this commentary underlines the impor...
برای هماهنگی آسان تر رله های جریان زیاد در شبکه های بزرگ و بهم پیوسته لازم است تا رله هایی به عنوان نقاط شروع هماهنگی یا همان نقاط شکست تعیین شود، نقاطی که در آن حلقه های شبکه در دو جهت ساعتگرد و پادساعتگرد باز می شوند. در گذشته روشی مبتنی بر سیستم خبره، عواملی همچون محل منابع و یا سطوح اتصال را درقالب قوانین خبره درنظرگرفته و باتوجه به آن ها به تعیین نقاط شکست پرداخته است. اما تعیین کوچکترین م...

this paper presents a probabilistic optimal power flow (popf) algorithm considering different uncertainties in a smart grid. different uncertainties such as variation of nodal load, change in system configuration, measuring errors, forecasting errors, and etc. can be considered in the proposed algorithm. by increasing the penetration of the renewable energies in power systems, it is more essent...
the present research was conducted with the aim of investigating the effect of high intensity interval and medium continuous training on anaerobic and aerobic power female basketball players. the research method was quasi-experimental with pretest and posttest, and included all female basketball players in firoozkooh city, tehran province, iran in 2015. twenty female basketball players were enr...
this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...
this paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. the power filter integrates a passive power filter which is a rl low-pass filter placed in series with the load, and an active power filter which comprises an rl in series with an igbt based voltage source converter. the filter is assumed...
