this paper presents a comparative analysis between two current control strategies, constant source power and generalized fryze current, used in active power filter (apf) applications having three different modulation methods. the hysteresis band (hb) and first-order delta-sigma modulation (dsm) as well as the second-order dsm is applied. the power section of the active power filter is viewed as...

optimal reactive power dispatch (orpd) is a multi-variable problem with nonlinear constraints and continuous/discrete decision variables. due to the stochastic behavior of loads, the orpd requires a probabilistic mathematical model. in this paper, monte carlo simulation (mcs) is used for modeling of load uncertainties in the orpd problem. the problem is formulated as a nonlinear constrained mul...

employees’ attitude towards his/her job differs across organization’s sector. the present study aimed to find out the differences in employee’s attitude in public and private sector. for this purpose, managers’ reward power and coercive power were taken as independent variables and their impact on employees’ job satisfaction (dependent variable) was examined in both sectors. sample of 130 respo...

a power divider (pd)/ power combiner (pc) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (siw) technology is proposed. an siw cavity is designed to provide a high quality factor filtering response and an smd resistor is attached between two output ports to realize the high isolation. the value of the applied resistor is calculated by using the ...

extended abstract 1- introduction power is regarded as an important social variable when studying any social structure and institution. accordingly, distribution of power in family structure has a great importance and could affect many familial experiences such as development of personality, socialization, self-esteem, solidarity, satisfaction, happiness, etc. (mahdavi & saboori khosroshahi, 20...
