a r t i c l e i n f o We examine the role of substitution from traditional to modern energy carriers and of differential rates of innovation in the use of each of these in economic growth in Sweden from 1850 to 1950. We use a simple growth model with a nested CES production function and exogenous factor-augmenting technological change and carry out a counterfactual simulation based on the econo...

Zero-energy city, sustainable City and zero-carbon city are new terms in cities’ energy management. In this study, a framework of designing a Low-Carbon Eco-City (LCEC) in urban sector of Mashhad with focus on sustainable supply of electrical energy has been simulated. For this purpose, the maximum potential of biomass renewable electricity and expansion of photovoltaic capacity- required to co...

The main share of energy consumption in the country and more than a third of its loss is in residential use. Per capita, household electricity consumption is far from the world standard, and the existence of subsidies for energy carriers in Iran, and consequently their low prices, causes occupants to pay less attention to energy consumption. Due to the policy of eliminating subsidies, the effec...

Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...

The aim of this article is to analyze SEC critically in relation to refinery industrial energy efficiency. In this study, the effect of various parameters such as input energy carriers, output energy, API value, and input refining oil was investigated. Specific energy consumption of unit and standard criterion was obtained 2.30 and 3.06 Gj/ton, respectively, that the total specific energy consu...
