In recent years, power electronic components introduce harmonic pollution on electric power systems. It makes the traditional electromechanical power meter can not act accurately when it feeds unbalanced and harmonic loads. Power quality analysis now tends to use digital signal technology. But it is hard to avoid measurement errors in estimating power quality by digital signal technology. In th...

patients and methods the study was conducted among 40 young rural pregnant women, 12 to 20 years old by implementing a questionnaire during 2012 to 2013 in four villages in southeast of iran. the women were exposed to high-risk factors such as shortage or lack of drinking water, high pressure electric power sources and chemicals released from burning gas both from cooking and cars as a fuel. th...

This paper is concerned with the estimation of total factor productivity (TFP) growth for the Iranian electric utilities during the period 1980-1993 on the basis of panel data. A translog cost function is used which accommodates firm - specific variability through a one - way error component model. The results show that the Iranian electricity supply industry experienced increasing returns to s...

This talk will discuss the emerging concept of a Cyber-Physical system, and how electric power systems of the future will have a significant cyber (computer) component. Correctness and security issues are discussed under the umbrella of non-interfering components for power systems applications. Biography Bruce McMillin received the B.S. in EE and M.S. in CS from Michigan Technological Universit...

This thesis examines two problems concerning the secure and reliable operation of the electric power grid. The first part studies the distributed operation of the electric power grid using the power flow problem, which is vital to the operation of the grid. The power flow problem is a feasibility problem for finding an assignment of complex bus voltages that satisfies the power flow equations a...

Axial Flux Permanent Magnet (AFPM) machines are attractive candidates for Electric Vehicles (EVs) applications due to their axial compact structure, high efficiency, high power and torque density. This paper presents general design characteristics of AFPM machines. Moreover, torque density of the machine which is selected as main objective function, is enhanced by using Genetic Algorithm (GA) a...
