This paper studies the mechanical configuration and the periodic gaits of multi-legged locomotion systems based on its kinematic and dynamic models. The purpose is to determine the system performance during walking and the best set of locomotion variables that minimize a set of optimization indices. In this perspective, are formulated two kinematic and four dynamic indices to quantitatively mea...

in this paper, reconfiguration problem of distribution network has been investigated toimprove reliability and reduce power loss by placement of renewable energy sources; i.e. solarcell and wind turbine. for this, four reliability indices are considered in objective function;which are as follows: system average interruption frequency index (saifi), system averageinterruption duration index (sai...

the main objective of this paper is to analysis the impact of information and communication technology (ict) on energy consumption in the mena region selected countries during the period 1995-2011. for this purpose, used the model presented by sadorsky (2012) and three indicators that measured ict: the number of internet users, the number of mobile lines and the number of telephone lines. also,...

savojbolagh is the main region of hydroponic greenhouse agriculture in iran and is of the capacity to produce the highest in greenhouse production strawberry. the aims followed in this study were to calculate the energy use pattern and determine the relationship between energy input in greenhouse strawberry production and its yield through a linear programming model as based on data envelopment...

In order to study the variation of electronic properties, a set of bithiophene derivatives has been ‎developed. Here, the effect of substitution on the aromaticity properties of some cyclic ‎bithiophene derivative compounds was investigated using theoretical calculations. Calculations ‎were performed at B3LYP/6-31+G (d,p) level; and calculated properties included energy, dipole ‎moment, total c...
