Abstract: Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward (C3H4) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of methylacetylene (C3H4) the pristine nanotubes is a bout -1.78kcal/mol. But when nanotube have been doped with Si and Al atomes, the adsorption energy of me...

Abstract: Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward pyrrole (C5H6N) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of pyrrole on the pristine nanotubes is a bout -16.37kcal/mol. But when nanotube have been doped with Si and Al atom...

with regard to the importance of scientific decision-making in power plants prioritization to produce electrical energy (power) from renewable energies (purified), in this paper, research with specialists opinions with respond to questionnaires provided upon three efficient operational criterion in position of three presented power plant in country which used wind, solar water energies for prod...

In this paper an optimal controller is proposed for a self-balancing electrical vehicle called Segway PT. This vehicle has one platform and two wheels on the sides and the rider stands on the platform. A handlebar, as a navigator, is attached to the body of Segway, with which the rider controls the vehicle. Since Segway uses electrical energy produced by batteries, resource consumption manageme...

this study investigates relation between accruals quality and auditor selection in the listed firms of tehran stock exchange (tse) during a five-year period from 2007 to 2011.  using correlation method and logistic regression technique, the results of this study indicate that client size, management change and accruals quality impact on selection of the big audit firms.  the results of this res...
