Although significant private investment is absorbed in different sectors of power systems, transmission sector is still suffering from appropriate private investment. This is because of the pricing policies of transmission services, tariffs, and especially for investment risks. Investment risks are due to the uncertain behaviour of power systems that discourage investors to invest in the transm...

the ever increasing rate of power consumption has led to an increase in public exposure to extremely low frequency magnetic fields (elf-mfs) and brought severe concerns about their health effects. considering previous studies and the facts about potential health effects of these fields, the present study aimed to evaluate the elf-mf flux densities from power distribution lines near hospitals in...

a filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. this design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. the high isolation between output ports is obtained by combining the half mode substrate integrated wa...

Power management strategies play a key role in the design process of hybrid electric vehicles. Electric Assist Control Strategy (EACS) is one of the popular power management strategies for hybrid electric vehicles (HEVs). The present investigation proposes a new framework to advance the EACS. Dynamic Programming method is applied to an HEV model in several drive cycles, and as a result, some op...

Political scientists bring important tools to the analysis of the coronavirus disease 2019 (COVID-19) pandemic, particularly a focus on the crucial role of power in global health politics. We delineate different kinds of power at play during the COVID-19 crisis, showing how a dearth of compulsory, institutional, and epistemic power undermined global cooperation and fuel...
