one of the most important issues about production structure and measurement of factors utilization in industry is the study of substitutability among the production factors. while, energy, for its particular features like finite and the direct relationship between energy usage and air pollution; and specifically abundance of energy resources and allocation of subsidies to different energy carri...

industrial energy consumption lies between 30% and 70% of the total energy consumed in selected countries. cement production is one of the most energy intensive industries all around the world. this paper deals with an energy audit analysis in a cement plant in iran. in all recent works, after performing an energy audit, different strategies are offered to reduce energy losses. generally, these...

in the sector of electricity production, the existence of investment resources limitation and environmental factors are the main factors that influence this process. the reduction of costs and the destructive impacts of environmental have been always mentioned by specialists. consequently, the drasticality of the environmental protection and the electric-energy production lead to focus on solar...

Because of electricity subsidies, electricity price in Iran is much lower than its real value, and the growth of electricity demand is much more than its rational rate, which in turn implies ever increasing investment in the electricity section by the Government. Therefore, the recent Government policies are based on elimination of electricity subsidies, followed by commissioning complete elect...

Unlike old-fashioned aircrafts that almost did not have avionics systems, up to date aircrafts have numerous avionics systems. Nearly all new aircrafts have devices for navigation, automatic flight control, collision avoidance systems, flight data recorder, weather radar system in addition to communication and monitoring systems. All of these devices employ embedded computer systems with growin...

Nowadays, electricity is one of the most significant infrastructures required for economic development of countries. Hence, predicting electricity demand is very important especially in industry as a major electricity-consuming sector. The majority of studies under the subject of electricity demand have been performed by econometrics and it is not possible to investigate the effect of different...
