Microgrid is a collection of electric loads, distributed generation units and battery storage operating as a controllable load which is able to supply the local loads. Air pollution due to fossil fueled vehicles increase by faculties development. Besides, shortage in fossil fuels increase the trends into electric vehicles. In this paper, optimal stochastic operation problem of microgrid in pres...
The electric solar wind sail (E-sail) is a space propulsion concept that uses the natural solar wind dynamic pressure for producing spacecraft thrust. In its baseline form, the E-sail consists of a number of long, thin, conducting, and centrifugally stretched tethers, which are kept in a high positive potential by an onboard electron gun. The concept gains its efficiency from the fact that the ...
We present a model for the ion distribution near a charged surface, based on the response of the ions to the presence of a single test particle. Near an infinite planar surface this model produces the exact density profile in the limits of weak and strong coupling, which correspond to zero and infinite values of the dimensionless coupling parameter. At intermediate values of the coupling parame...
The article examines the experience of higher education institutions in transition to distance learning, widespread implementation electronic science and special e-courses context modernization modern education. Based on modified Xi square table formula, empirical value three-category questionnaire answers consisting four options was calculated. effectiveness study tested basis dynamic changes ...
In addition to the significant contribution of electric vehicles energy consumption and carbon emissions, fact that they are quiet highly sustainable in terms use causes an increase demand. Buses, which a type public transportation vehicle among vehicles, great importance for transportation, providing fuel savings society general being solution traffic problem. Gathering two separate phenomena ...
many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...
