The article concerns the issue of retrofitting (i.e., conversion worn-out diesel buses into electric buses). As this solution is often cheaper than purchasing new buses, it can be attractive for low-population areas with a weaker economic infrastructure. aims to present an original method rapidly selecting components traction system, such as motor, inverter, and transmission systems, combined b...

the levy-type analytical solution is employed for the problem of bending of cross-ply and antisymmetric angle-ply piezoelectric hybrid laminated plates with at least two simply supported opposite edges. the governing equations of equilibrium are derived in the framework of the first-order shear deformation plate theory. the equations are classified according to the crystallography type of piezo...

Objective: Purpose is to study the role of customer knowledge interaction and intention to buy consumers in the electrical industry with an information behavior approach. Method: Develomental qualitative method was used. Population included   experts in marketing and consumer behavior, especially in the electrical industry. Via targeted snowball method sample of 14 experts were selected for a s...

in this study we investigate the effect of atoms such as b, n, ge and sn on the optical and the electrical properties of capped (5, 0) zigzag carbon nanotube, using dft calculation method. these elements were attached to the one end of the carbon nanotube. we considered four different structure designs as possible candidates for a p-n junction device. the electrical properties of these structur...

Electric potential measurement technique (tomography) was introduced as a nondestructive method to evaluate concrete properties and durability. In this study, numerical meshless method was developed to solve a differential equation which simulates electric potential distribution for concrete with inclusion in two dimensions. Therefore, concrete samples with iron block inclusion in different loc...
